BACKGROUND OF THE INVENTION
Field
The apparatus, methods, and kits disclosed herein relate to apparatus for the capture of garbage within a sump.
Background
Water such as, for example, storm water, sanitary wastewater may contain pollutants in the form of garbage that may be sufficiently buoyant to float about the water surface. In various aspects, the water may be channeled through various existing pipes or other drainage channels that pass through one or more sumps. In order to control pollution, it may be desirable to utilize these sumps to capture garbage entrained in the water. In addition, it may be desirable to capture particulates entrained in the water within the sumps.
While devices are available that capture garbage within the sump by preventing the garbage from exiting the sump through outflow pipe(s), these devices may inhibit the flow of water from the sump into the outflow pipe(s). In addition, various existing devices are bulky, difficult to install, and may not be inserted through a manhole entrance into the sump, as the manhole entrance may be limited in size. In addition, the sump may be a confined space that is difficult to work in. The confined space of the sump with limited access into the sump may cause difficulty with retrofitting an existing sump with devices that capture garbage within the sump.
Accordingly, there is a need for improved apparatus that captures floatable garbage within the sump as well as related methods of assembly and kits that, for example, facilitate the retrofit of existing sumps with such apparatus.
BRIEF SUMMARY OF THE INVENTION
These and other needs and disadvantages may be overcome by the apparatus disclosed herein. Additional improvements and advantages may be recognized by those of ordinary skill in the art upon study of the present disclosure.
A garbage guard apparatus is disclosed herein. In various aspects, the garbage guard apparatus may be mounted in a sump comprising an outflow pipe with an outflow pipe entrance that conveys water from the sump, and the sump may be accessed through a manhole entrance of diameter d. The garbage guard apparatus includes multiple panels, with each panel of the multiple panels having panel width W that is less than diameter d of the manhole entrance to allow for passage of each panel through the manhole entrance into the sump, in various aspects. A flange is formed on each longitudinal side of each panel with all flanges being symmetric to allow a flange of one panel to mate with any flange of any other panel, in various aspects. The panels when flangeably secured to one another within the sump form a panel assembly, in various aspects. The panel assembly so formed is then attached to the sidewall of the sump about the outflow pipe entrance of the outflow pipe with a lower end below an invert of the pipe entrance and an upper end above a crown of the pipe entrance, in various aspects. When so attached to the sidewall of the sump, the panel assembly defines a passage and the water passes from the sump around the lower end of the panel assembly into the passage and thence into the pipe entrance of the outflow pipe with buoyant garbage being retained within the sump by the panel assembly, in various aspects. Related kits, methods of assembly, and methods of use are also presented in this disclosure.
This summary is presented to provide a basic understanding of some aspects of the apparatus and methods disclosed herein as a prelude to the detailed description that follows below. Accordingly, this summary is not intended to identify key elements of the apparatus and methods disclosed herein or to delineate the scope thereof.

DETAILED DESCRIPTION OF THE INVENTION
In various aspects, the garbage guard apparatus disclosed herein includes multiple panels, each panel of the multiple panels having panel width W that is less than a diameter d of a manhole entrance into a sump in order to allow the passage of each panel through the manhole entrance into the sump for assembly within the sump. A flange is formed on each longitudinal side of each panel, and all flanges are symmetric with one another to allow a flange of one panel to mate with any flange of any other panel, in various aspects. The panels may be lowered through the manhole entrance into a sump where the panels may then be assembled into a panel assembly by flanged securement of the panels to one another, in various aspects. In other aspects, the flanges are omitted from the panels and the panels are secured to one another using angle brackets secured along edges of adjacent panels. In some aspects, the panels are planar, while, in other aspects, the panels assume various curved shapes. In various aspects, various features of the garbage guard apparatus may facilitate retrofitting of existing sumps with the garbage guard apparatus as well as installation of the garbage guard apparatus during construction of new sumps. Related kits, methods of assembly, and methods of use are also disclosed herein.
Water is conveyed from the sump through a pipe entrance into the outflow pipe, in various aspects. The panel assembly is attached to a sidewall of the sump about the pipe entrance of the outflow pipe with a lower end of the panel assembly lying below an invert of the pipe entrance and an upper end of the panel assembly lying above a crown of the pipe entrance, in various aspects. The panel assembly defines a passage and the water passes from the sump around the lower end into the passage and thence into the pipe entrance of the outflow pipe with buoyant garbage being retained within the sump by the panel assembly, in various aspects. The passage may be sized to lessen hydraulic losses as the water passes through the passage into the pipe entrance.
A top cap made either of screen or of solid material may be placed on the upper end of the panel assembly to capture garbage when water in the sump overtops the panel assembly. The top cap formed of screen captures garbage entrained in the water while allowing water to pass through the top cap. The top cap formed of solid material blocks flow into the passage around the upper end of the panel assembly, and captures garbage including floating liquid(s) such as oil or grease. Garbage may be removed from the sump through the manhole as necessary.
FIGS. 1A, 1B, 1C illustrate exemplary garbage guard apparatus 10 including panels 22a, 22b, 22c of panel assembly 20 secured within sump 18 of manhole 12. Panels 22a, 22b, 22c are generally planar and rectangular with panel width W and panel height Y, as illustrated, and may be either square or oblong. In other implementations, the panels may be curved (see FIG. 8). Water 95, as indicated by the arrows in FIGS. 1A, 1B, passes through pipe exit 14 of inflow pipe 13 into sump 18, through sump 18, and from sump 18 through pipe entrance 16 into outflow pipe 15. Panel assembly 20 is secured to side wall 17 of manhole 12 proximate pipe entrance 16 of outflow pipe 15 to capture garbage 99 entrained in the water 95 in order to prevent the garbage 99 from being conveyed from sump 18 into outflow pipe 15 with water 95. Panel assembly 20 retains garbage 99 in sump 18 as garbage 99, which is floating about water surface 97 cannot pass through panel assembly 20. Garbage 99 is thus captured in sump by panel assembly 20 including top cap 40, and garbage 99 may be removed from sump 18 as necessary by user, for example, by vacuum truck or other cleaning devices. Note that, while FIG. 1B includes garbage 99, garbage 99 is omitted from FIG. 1A for clarity of explanation. Garbage 99 may generally have a specific gravity less than that of water, and garbage 99 may include, for example, various floatables, such as, for example, plastic bottles, empty cans or containers, floatable trash, plastics such as Styrofoam, wood based material such as branches, leaves, foliage, and lumber, grease and oils, petrochemicals, fats, and other generally buoyant materials that may be in the form of discrete materials, particles, floatable liquids, or various combinations thereof.
Panel assembly 20 is formed of panels 22a, 22b, 22c flangeably secured to one another, as illustrated, for example, in FIG. 2A. Side 23a of panel 22a is attached to side 21b of panel 22b, and side 23b of panel 22b is attached to side 21c of panel 22c, and sides 21a, 23c of panels 22a, 22c, respectively, are attached to sidewall 17 to secure panel assembly 20, in this implementation. Sides 25a, 25b, 25c of panels 22a, 22b, 22c, respectively, form lower end 24 of panel assembly 20, and sides 27a, 27b, 27c of panels 22a, 22b, 22c, respectively, form upper end 26 of panel assembly 20, as illustrated in FIGS. 1A, 1B (also see FIG. 2A). Panels 22a, 22b, 22c may be formed of plastic, such as polyvinyl chloride (PVC) in certain implementations. In various implementations, panels 22a, 22b, 22c may be formed, for example, of galvanized sheet steel, stainless steel, high density polyethylene (HDPE), fiberglass, aluminum, or conbinations thereof, and the material(s) that forms panels 22a, 22b, 22c in a specific implementation may be selected to resist corrosion by the particular aqueous environment within which the panels 22a, 22b, 22c will be used in that specific implementation.
As illustrated in FIG. 2B, when secured to sidewall 17, inner side 39 of panel assembly 20 defines passage 35 between lower end 24 and upper end 26, and water 95 flows from sump 18 into passage 35 through lower end 24 and from passage 35 into outflow pipe 15 through pipe entrance 16. The buoyancy of garbage 99 holds garbage 99 proximate water surface 97 as water 95 flows into passage 35 through lower end 24 and, thence, into outflow pipe 15 through pipe entrance 16. Panel assembly 20 blocks garbage 99 from entering outflow pipe 15 thereby retaining garbage 99 in sump 18. Garbage 99 may collect about outer side 37 of panel assembly 20 that faces outward into sump 18.
Top cap 40 is secured over passage 35 at upper end 26 to enclose passage 35 at upper end 26 in order to prevent garbage 99, which generally floats about water surface 97, from entering passage 35 at upper end 26 in the event that water surface 97 in sump 18 approaches or overtops the upper end 26 of panel assembly 20, in this implementation. Top cap 40 may be formed of galvanized steel, stainless steel, copper, brass, plastic, aluminum, or other corrosion resistant material or combination of materials, in various implementations. Top cap 40 of exemplary garbage guard apparatus 10 is formed as a screen 46 having apertures, such as aperture 41, sized to allow passage of water through top cap 40 from sump 18 into passage 35 and thence into pipe entrance 16 of outflow pipe 15 while retaining garbage 99 in sump 18. Garbage 99 of sizes larger than aperture 41 is captured by screen 46, and, thus, retained in sump 18. Screen 46 includes screens as well as sheets of perforated material, in various implementations. In other implementations, such as garbage guard apparatus 400 illustrated in FIG. 7, for example, wherein garbage includes floating liquids such as greases, oils, fats, petrochemicals, top cap 440 is formed of solid material 446 (no apertures), to trap floating liquids for later removal should the water surface in the sump, such as water surface 97 in sump 18, approach or overtop the upper end 426 of panel assembly 420.
As illustrated in FIG. 1A, inflow pipe 13 and outflow pipe 15 are set at angle α with respect to one another, and angle—a may vary between 0° and 360°, in various implementations. Multiple inflow pipes, such as inflow pipe 13, or multiple outflow pipes, such as outflow pipe 15, may flow into or out from sump 18, respectively, and the pipe exits, such as pipe exit 14, and the pipe entrances, such as pipe entrance 16, may have various elevations with respect to sump floor 11, in various implementations. Note that in some implementations, inflow pipe 13 is omitted so that sump 18 has only outflow pipe 15. Inflow pipe 13 and outflow pipe 15 may have various cross-sectional shapes such as round, ovoid, rectangular, square, arched, horseshoe, or elliptical, and may differ from one another in cross-sectional shape, as would be readily recognized by those of ordinary skill in the art upon study of this disclosure. Inflow pipe 13 and outflow pipe 15 may be made of steel, concrete, clay, cast iron, brick, or other material or combinations of materials, as would be readily recognized by those of ordinary skill in the art upon study of this disclosure. Manhole 12 including sump floor 11 and sidewall 17 may be formed of various materials or combinations of materials such as pre-cast concrete, cast-in-place concrete, brick, masonry, and so forth, as would be readily recognized by those of ordinary skill in the art upon study of this disclosure.
As illustrated in FIG. 1B, manhole 12 has manhole entrance 19 of diameter d that is enclosed by manhole cover 47 (illustrated set apart from manhole entrance 19). Manhole cover 47 is removable to allow access to sump 18 through manhole entrance 19. Manhole cover 47 may be a generally solid cover that encloses sump 18 or manhole cover 47 may be formed as a grating, grill, or so forth, in various implementations. Manhole entrance 19 may be circular, as illustrated, or may assume other shapes such as rectangular or square in other implementations, and manhole cover 47 may be correspondingly shaped to conform to the shape of manhole entrance 19. Diameter d includes equivalent dimension(s) for a non-circular manhole entrance.
FIG. 1C illustrates placement of panel assembly 20 with respect to pipe entrance 16 of outflow pipe 15. Note that panels 22a, 22b, 22c of panel assembly 20, which are planar in this implementation, are generally vertically aligned in a vertical plane, in this implementation. Diameter D is the diameter of the outflow pipe 15 at pipe entrance 16, which has invert 86 and crown 88, as illustrated.
Table 1 includes exemplary dimensions of exemplary garbage guard apparatus 10 as illustrated in FIG. 1C. Because the dimensions given in Table 1 are exemplary, it should be recognized that the dimensions of various implementations may differ from the exemplary values given in Table 1, for example, in order to conform to a specific application. Diameter D may be, for example, a standard pipe diameter. S may be selected so as to allow water flow under panel assembly 20 without inhibiting flow while trapping garbage 99. Panel width W and panel height Y may be selected according to D, for example, with panel width W and panel height Y being larger in installations with a larger diameter D of the outflow pipe 15 at pipe entrance 16. Top cap height Z may be altered from the exemplary value given in Table 1 to any height that suits a specific application. Because diameter d of manhole entrance 19 may restrict placement within sump 18, panel width W is selected to be less than diameter d of manhole entrance 19 in order that panels, such as panels 22a, 22b, 22c, may be passed through manhole entrance 19 into sump 18 for fabrication into panel assembly 20 within sump 18. While panels 22a, 22b, 22c are illustrated as having similar panel width W, the panel width W of each of panels 22a, 22b, 22c may differ, in other implementations.

FIGS. 2A, 2B further illustrates assembly of panels 22a, 22b, 22c and top cap 40 into at least portions of panel assembly 20. As illustrated in FIG. 2A, sides 21a, 21b, 21c of panels 22a, 22b, 22c include flanges 31a, 31b, 31c, respectively, and sides 23a, 23b, 23c of panels 22a, 22b, 22c include flanges 33a, 33b, 33c, respectively. Flange 33a of panel 22a is attached to flange 31b of panel 22b in order to attach side 23a of panel 22a to side 21b of panel 22b, as illustrated. Flange 33b of panel 22b is attached to flange 31c of panel 22c in order to attach side 23b of panel 22b to side 21c of panel 22c, as illustrated. Fasteners, such as fasteners 42a, 42b, 42c, 42d, are insertably engaged through holes, such as holes 43a, 43b, 43c, 43d, provided matingly in flanges 31b, 31c, 33a, 33b to attach side 23a of panel 22a to side 21b of panel 22b and to attach side 23b of panel 22b to side 21c of panel 22c, as illustrated. Fasteners, such as fastener 42a, 42b, 42c, 42d, include, for example, bolts, screws, rivets, clips, and combinations thereof, and various numbers of holes in the flanges and corresponding fasteners may be provided to join the flanges to one another, in various implementations. In this implementation, flanges 31a, 33a, flanges 31b, 33b, and flanges 31c, 33c are unitary with panels 22a, 22b, 22c, respectively, and may be formed during manufacture of the panels. In other implementations, panels may not have flanges formed during manufacture, but instead use angle brackets (see FIGS. 9A, 9B) that are manufactured separately and affixed to each panel at time of installation to secure the panels to one another. Angle brackets, such as angle brackets 663a, 663b of FIGS. 9A, 9B, may be used in addition to flanges 31a, 33a, flanges 31b, 33b, and flanges 31c, 33c, to join the panels 22a, 22b, 22c to one another with the angle brackets reinforcing the flanges.
Top cap 40 is then overlaid upon the assembly of panels 22a, 22b, 22c at upper end 26 to enclose passage 35 at upper end 26 of panel assembly 20. When top cap 40 is secured to upper end 26 of panel assembly 20, aprons 49a, 49b, 49c extend over portions of outer side 37 of panel assembly 20 to enclose ports 29a, 29b, 29c, respectively, to prevent garbage, such as garbage 99 from passing through ports 29a, 29b, 29c into passage 35 and thence into outflow pipe 15. Various fasteners may be used to secure top cap 40 to panel assembly 20. Aprons 49e, 49f may be secured to sidewall 17 of sump 18 to further secure top cap 40 in place at upper end 26 of panel assembly 20.
As illustrated in FIG. 2A, spacers 51a, 51b are optionally interposed between flanges 33a, 31b and between flanges 33b, 31c, respectively. Spacers, such as spacers 51a, 51b, are optional, and accordingly spacers may be omitted in certain implementations. Spacers 51a, 51b may be made of rubber, neoprene, or other such flexible conformable, sealing material. When included, spacers 51a, 51b may, for example, seal any gap(s) between flanges 33a, 31b and between flanges 33b, 31c to inhibit the flow of water 95 between flanges 33a, 31b and between flanges 33b, 31c, or spacers 51a, 51b may aid in the mating of flanges 33a, 31b and the mating of flanges 33b, 31c. Holes, such as holes 53a, 53b, may be provided in spacers 51a, 51b, and fasteners, such as fasteners 42a, 42b, 42c, 42d, may be received within the holes in spacers 51a, 51b. In order to prevent leakage between the panels, flanges, such as flanges 31a, 31b, 31c, 33a, 33b, 33c may be, for example, at least 1″ in width (inside measurement). In implementations that include spacers, such as spacers 51a, 51b, the spacers may be sized in conformity to the flanges.
As illustrated in FIG. 2A, flanges 31a, 33c may be attached to sidewall 17 using fasteners, such as fasteners 44a, 44b, insertably received in holes, such as hole 45a, 45b, to engage flanges 31a, 33c with sidewall 17, and, thus, attach panel assembly 20 to sidewall 17. Fasteners, such as fastener 44a, 44b, include, for example, bolts, concrete anchors, masonry screws, and combinations thereof, in various implementations, as may depend upon the material of sidewall 17, and various types of fasteners may be used throughout garbage guard apparatus 10 as may be appropriate. Various numbers of holes, such as holes 45a, 45b, and corresponding fasteners, such as fasteners 44a, 44b, may be provided for attachment of the flanges, such as flanges 31a, 33c, to sidewall 17 of manhole 12, in various implementations. Fasteners, such as fasteners 42a, 42b, 42c, 42d, 44a, 44b, may be, for example, 7/16″ in diameter and made of stainless steel, galvanized steel, or other corrosion resistive material(s). In various implementations, shims, furring strips, spacers, gaskets, and so forth (not shown) may be interposed between the flanges 31a, 33c and sidewall 17, and flanges 31a, 33c may be anchored thereto and not directly to sidewall 17, as would be readily recognized by those of ordinary skill in the art upon study of this disclosure.
FIG. 2B illustrates the assembled panel assembly 20 secured to sidewall 17 of sump 18 with panels 22a, 22b, 22c secured to one another. Top cap 40, as illustrated in FIG. 2B, is secured to panels 22a, 22b, 22c to enclose passage 35 at upper end 26 of panel assembly 20 in order to prevent the inflow of garbage 99 into passage 35, and, thence, into outflow pipe 15. Aprons 49e, 49f and portions of top cap 40 proximate top cap edge 48 are secured to sidewall 17, and aprons 49a, 49b, 49c are secured to panels 22a, 22b, 22c to secure top cap 40 in place. Note that top cap edge 48 of top cap 40, in this implementation, is elevated above upper end 26 of panel assembly 20 by amount Z to slant top cap 40 to prevent garbage 99 from accumulating on top cap 40. Garbage 99 would roll off of top cap 40, which is slanted, in this implementation. In other implementations, top cap 40 may be generally horizontal (Z 0).
FIGS. 3A, 3B illustrated panel 22b of panel assembly 20, and panels 22a, 22b may be essentially the same as panel 22b, in this configuration. As illustrated, panels 22a, 22b, 22c are rectangular in shape with panel width W and panel height Y. Panel width W, which is less than panel height Y, may be less than diameter d of manhole entrance 19 to allow insertion of panels 22a, 22b, 22c into sump 18 through manhole entrance 19. Ports 29a, 29b, 29c are disposed in panels 22a, 22b, 22c proximate top sides 27a, 27b, 27c, respectively, to allow the user to manipulate panels 22a, 22b, 22c. For example, either port 29a, 29d, port 29b, 29d, and port 29c, 29f of panel 22a, 22b, 22c, respectively, may be engaged with cable 63 by hook 61 including other attachment mechanisms. Then cable 63, which may be under control of a hoist (not shown), may be used to lower panels 22a, 22b, 22c lengthwise into sump 18 through manhole entrance 19 for assembly into panel assembly 20 within sump 18 and attachment to sidewall 17. Cable 63 may be, for example, a cable or a rope, and cable 63 may be manipulated by hand or by a hoist including, for example, a come-along, crane, or winch.
As illustrated, panel 22b is symmetric about lateral axis 101 that passes through panel 22b midway of length Y, and panel 22b is symmetric about longitudinal axis 103 that passes through panel midway of width W. Holes, such as holes 43a, 43b, 43c, 43d, are disposed symmetrically along flanges 31b, 33b with respect to one another and with respect to lateral axis 101. For example, holes 43a, 43b are placed at the same distance from lateral axis 101 as holes 43d, 43c, respectively. Panels 22a, 22b, 22c are symmetric with respect to one another so that the holes in the flanges align with one another when the flanges are adjoined, with holes in the same position with respect to the lateral axis in the flanges. For example, flange 31b of panel 22b will mate with any of flanges 31a, 33a of panel 22a or flanges 31c, 33c of panel 22c and the holes will align. Thus, panels 22a, 22b, 22c may be lowered into sump 18 by either of ports 29a, 29d, ports 29b, 29e, and ports 29c, 29f, respectively, and will be properly oriented for assembly including mating engagement of the flanges within sump 18 (may require rotation about longitudinal axis, such as longitudinal axis 103 to achieve proper orientation). Note that, as illustrated, flanges 31a, 33a, 31b, 33b, 31c, 33c are faced outward as part of outer side 37 of panel assembly 20 to allow the user to place fasteners through the flanges in order to join the flanges together or to engage flanges with the sidewall 17. Orientation of flanges 31a, 33a, 31b, 33b, 31c, 33c outward opposite of passage 35, as illustrated, may facilitate assembly of panel assembly 20 within sump 18 as the user may access the flanges from sump 18 not from within passage 35. As illustrated in FIG. 3B, flanges 31b, 33b, are set at angle β with respect to the remainder of panel 32b. Angle β may be for example, about 120°, and angle β may range from about 90°, to about 180°, in various implementations.
FIG. 4 illustrates exemplary garbage guard apparatus 100 including panel assembly 120 secured within sump 118 of manhole 112. Panel assembly 120 is formed of two panels, panels 122a, 122b, in this implementation. Water 195, as indicated by the arrows passes through pipe exit 114 of inflow pipe 113 into sump 118, through sump 118, and from sump 118 through pipe entrance 116 into outflow pipe 115. Panel assembly 120 is secured to sidewall 117 of sump 118 proximate pipe entrance 116 of outflow pipe 115 to capture garbage, such as garbage 99, entrained in the water 195 as water 195 passes from sump 118 into outflow pipe 115.
As illustrated in FIG. 4, panels 122a, 122b are joined together to form panel assembly 120 having a V-shaped structure. Flange 133a of panel 122a is joined to flange 131b of panel 122b by fasteners (not shown) received in holes (not shown) disposed about flanges 133a, 131b for that purpose thereby forming panel assembly 120. Panel assembly 120 is attached to sidewall 117 of sump 118 by fasteners engaged with flanges 131a, 133b.
FIG. 5 illustrates exemplary garbage guard apparatus 200 including panel assembly 220 secured within sump 218 of manhole 212. Panel assembly 220 is formed of four panels, panels 222a, 222b, 222c, 222d, in this implementation. The panel assembly, such as panel assembly 220, may be formed of any number of panels as may be required to accommodate the size of the outflow pipe 215, in various implementations. Water 295, as indicated, passes through first pipe exit 214 of first inflow pipe 213 into sump 218 and from second pipe exit 274 of second inflow pipe 273 into sump 218. Water 295 flow through sump 218 and thence into outflow pipe 215 through pipe entrance 216. Panel assembly 220 is secured to sidewall 217 of sump 218 proximate pipe entrance 216 of outflow pipe 215 to capture garbage, such as garbage 99, entrained in the water 295 in order to prevent the garbage from passing into outflow pipe 215.
As illustrated in FIG. 5, panels 222a, 222b, 222c, 222d are joined together to panel assembly 220. Flange 233a of panel 222a is joined to flange 231b of panel 222b, flange 233b of panel 222b is joined to flange 231c of panel 222c, flange 233c of panel 222c is joined to flange 231d of panel 222d to form panel assembly 220. Flanges 231a, 233d are attached to sidewall 217 of sump 218 to secure panel assembly 220 to sidewall 217. Various fasteners (not shown) are received in holes (not shown) disposed about flanges 231a, 233a, 231b, 233b, 231c, 233c, 231d, 233d to join the flanges 233a, 231b, 233b, 231c, 233c, 231d together or to secure flanges 231a, 233d to sidewall 217, as illustrated in FIG. 5.
FIGS. 6A, 6B, 6C illustrate exemplary garbage guard apparatus 300 including panel assembly 320 and flow baffle 350 secured within sump 318 of manhole 312. In this implementation, panel assembly 320 is formed of panels 322a, 322b, 322c that are attached to one another and to sidewall 317 of manhole 312. Water 395, as indicated, passes through pipe exit 314 of inflow pipe 313 into sump 318 and through sump 318 into outflow pipe 315 through pipe entrance 316. Panel assembly 320 is secured to sidewall 317 of sump 318 proximate pipe entrance 316 of outflow pipe 315 to capture garbage, such as garbage 99, entrained in the water 395 in order to prevent the garbage from passing into outflow pipe 315.
Flow baffle 350 is disposed within sump 318, as illustrated in FIGS. 6A, 6B, to dissipate the energy of flow entering sump 318 from inflow pipe 313. Flow baffle 350 is generally planar and is disposed vertically within sump 318. Flow along centerline 301 of inflow pipe 313 strikes the plane of the flow baffle 350. Sediment may be carried into sump 318 by inflow of water 395 from inflow pipe 313, and flow baffle 350 may enhance the capture of sediment within sump 318. The position, size, and shape of flow baffle 350, and the size and shape of the openings 394 within flow baffle 350, are selected to reduce or eliminate scour and washout of sediment from sump 318 into outflow pipe 315, in various implementations. Thus, the combination of flow baffle 350 with panel assembly 320 may enhance the removal of both sediment and garbage from water 395 as water 395 passes through sump 318.
When flow baffle 350 is emplaced in sump 318, water 395 may flow over side 355 of flow baffle 350 as a weir, and water may flow between side 353 of flow baffle 350 and sump floor 311. Openings 394 pass through flow baffle 350 between surface 356 and surface 358 are disposed about flow baffle 350, and water 395 may flow through openings 394 of flow baffle 350. The openings 394 may be generally similar in size and shape, as illustrated in FIG. 6C, or the openings, such as openings 394, may vary in size, shape, or combinations of size and shape, in other implementations. Openings, such as openings 394, may be disposed about the flow baffle 350 such that the flow baffle 350 may have a percent of open area ranging from about 40% to about 50%, and the diameter including other equivalent dimension of openings 394 may range from about 2 inches to about 6 inches, in various implementations. Table 2 includes exemplary dimensions of an exemplary flow baffle 350 of exemplary garbage guard apparatus 300. Note that the dimensions given in Table 2 are exemplary only may be altered in various implementations, for example, in order to conform to a specific application.

FIG. 7 illustrates exemplary garbage guard apparatus 400 including panels 422a, 422b, 422c secured to one another and secured to sidewall 417 as panel assembly 420. Top cap 440, as illustrated in FIG. 7, is secured to panels 422a, 422b, 422c to enclose passage 435 at upper end 426 of panel assembly 420 in order to prevent the inflow of garbage, such as garbage 99, into passage 435, through upper end 426. Top cap 440, in this implementation, is generally horizontal (Z≈0), and top cap 440 is formed of solid material 446 through which water and other liquids will not pass in order to capture, for example, garbage in the form of grease and oils, petrochemicals, fats, and other generally buoyant liquids. In exemplary garbage guard apparatus 10, in which top cap 40 is formed of screen 46, the top cap height Z may be essentially zero, as in exemplary garbage guard apparatus 400 illustrated in FIG. 7. Similarly, in exemplary garbage guard apparatus 400, in which the top cap 440 is formed of solid material 446, the top cap height Z may have some finite value to slant top cap 440, as in garbage guard apparatus 10 illustrated in FIG. 2B. In certain implementations, at least portions of top cap edge 448 may be non-sealingly disposed with respect to sidewall 417 to allow air to pass between top cap edge 448 and sidewall 417 in order to relieve vacuum pressures within passage 435 that may cause siphoning or cavitation.
FIG. 8 illustrates portions of exemplary garbage guard apparatus 400 including panel 522 that is curved in the horizontal (W) dimension, in this implementation. Panel 522 includes flanges 521, 523 that are faced toward outer side 537 of panel 522. Several panels such as panel 522 may be flangably secured to one another to form a panel assembly 520 with inner side 539 defining at least in part a passage, such as such as passage 35, 135, 235, 335, 435. In other implementations, the panel(s) may, for example, be curved in the vertical dimension or in both the horizontal and vertical dimensions.
FIGS. 9A, 9B illustrate portions of exemplary garbage guard apparatus 500 including panels 622a, 622b secured to one another by angle brackets 663a, 663b to form at least a portion of panel assembly 620. In this implementation, panels 622a, 622b are flat sheets of material such as sheet steel or sheet aluminum, stainless steel, HPDE or combinations thereof devoid of flanges, and angle brackets 663a, 663b, nay be formed, for example, of steel, aluminum, stainless, steel, fiberglass, various plastics such as HPDE, and combinations thereof. Angle bracket 663a is secured to panels 622a, 622b about outer side 637 of panel assembly 620, and angle bracket 663b is secured to panels 622a, 622b about inner side 639 of panel assembly 620, in this implementation. Various fasteners may be used to secure angle brackets 663a, 663b to panels 622a, 622b, and various pre-drilled holes that accommodate the fasteners may be provided matchingly in angle brackets 663a, 663b and in panels 622a, 622b. Various combinations of angle brackets, such as angle brackets 663a, 663b may be used to secure panels 622a, 622b to one another about outer side 637, inner side 639, or both outer side 637 and inner side 639. For example, both angle brackets 663a, 663b may be utilized as illustrated, while, in other implementations, only angle bracket 663a is utilized. As illustrated in FIG. 9B, angle bracket 663a has height Y that matches the height of panels 622a, 622b. In other implementations, angle bracket 663a may have a height less than panel height Y with several angle brackets being disposed lengthwise to secure panels 622a, 622b to one another. Angle brackets 622a, 622b define angle γ at which panels 622a, 622b are positioned with one another, and angle γ may range from about 90° to about 180°, in various implementations.
FIG. 10 illustrates exemplary process of assembly 700 of a panel assembly of a garbage guard apparatus, such as panel assembly 20, 120, 220, 320, 420, 520, 620 of garbage guard apparatus 10, 100, 200, 300, 400, 500, 600 respectively. Process of assembly 700 starts at step 701. At step 705, panels, such as panels 22a, 22b, 22c, 122a, 122b, 222a, 222b, 222c, 222d, 322a, 322b, 322c, 422a, 422b, 422c, 522, 622a, 622b, are inserted into the sump, such as sump 18, 118, 218, 218, 318 of a manhole, such as manhole 12, 112, 212, 312, through a manhole entrance, such as manhole entrance 19. The panels are sized to pass through the manhole entrance and to be received within and manipulated for assembly within the sump (i.e., width W is less than diameter d of the manhole entrance), in various implementations. The panels may be lengthwise self-symmetric and symmetric with respect to one another so that the panels mate with one another irrespective of orientation.
With the panels received within the sump, the flanges, such as flanges 33a, 31b, 33b, 31c, flanges 133a, 131b, and flanges 233a, 231b, 233b, 231c, 233c, 231d, are joined together to form the panel assembly, at step 610. Flanges, such as flanges 31a, 33c, flanges 131a, 133b, and flanges 231a, 233d, are attached to the sidewall, such as sidewall 17, 177, 217, 317, 417 of the sump, at step 615. Fasteners, such as fasteners 42a, 42b, 42c, 42d, may be used to join the flanges together, and fasteners, such as fasteners 44a, 44b, may be used to attached the panel assembly to the sidewall. Holes, such as holes 43a, 43b, 43c, 43d and holes 44a, 44b, may be disposed about the flanges to receive fasteners that join the flanges together or secure the flanges to the sidewall. Spacers, such as spacers 51a, 51b, may be interposed between the flanges during the joining of the flanges together, in certain implementations. Alternatively, angle brackets, such as angle brackets 663a, 663b, may be utilized to join together panels, such as panels 622a, 622b, that are devoid of flanges. Angle brackets may be used to reinforce flanges, in certain implementations.
The panels may be manipulated using ports, such as ports 29a, 29b, 29c, 29d, 29e, 29f, 429a, 429b, 429c, 429d, as the panels are inserted through the manhole entrance into the sump, as the panels are manipulated within the sump during assembly of the panel assembly, or as the panel assembly is attached to the sidewall. A cable, such as cable 63, may be removably engaged the panels using the ports, and the cable or cable and panel in combination may be manipulated either by hand or mechanically. When the cable is attached to the port, the height H of the panel is oriented vertically by gravity so that width W passes through the manhole entrance and the panel is oriented for attachment to other panels in order to form the panel assembly.
A top cap, such as top cap 40, 440, may be placed over a passage, such as passage 35, 135, 235, 335, 435, defined by the panel assembly at upper end, such as upper end 26, 426, of the panel assembly. Steps 710, 715 may be performed consecutively in either order or steps 710, 715 may be performed concurrently at the choice of the user. Exemplary process of assembly 700 ends at step 729.
In operation of the garbage guard apparatus, water, such as water 95, 195, 295, 395, flows from an inflow pipe (or pipes), such as inflow pipe 13, 113, 213, 273, 313, into the sump. Water may flow into the sump through the manhole entrance. The water then passes from the sump through the passage defined by the panel assembly into a pipe entrance, such as pipe entrance 16, 116, 216, 316 of an outflow pipe such as outflow pipe 15, 115, 215, 315. Garbage, such as garbage 99, is held by buoyant forces proximate a water surface, such as water surface 97 of the water in the sump as the water is drawn into the passage so that the panel assembly prevents the garbage from being drawn into the outflow pipe. The panel assembly skims garbage from the water surface as the water flows through the passage into the outflow pipe. A top cap, such as top cap 40, 440, may enclose the passage at the upper end, such as upper end 26, 426, of the panel assembly to prevent garbage from being carried into the passage in the event the panels of the panel assembly are overtopped. The top cap may be slanted to prevent garbage from accumulating on the top cap. The top cap may be formed of a screen, such as screen 46, or of solid material, such as solid material 446, in various implementations. The top cap formed of solid material may skim garbage that includes floating liquids from the water when the water overtops the panel assembly. A flow baffle, such as flow baffle 360, may be interposed in the sump between the pipe exit, such as pipe exit 14, 114, 214, 274, 314, of the inflow pipe and the panel assembly to enhance capture of sediment in the sump. The user may then remove garbage or sediment accumulated in the sump as needed.
The foregoing discussion along with the Figures discloses and describes various exemplary implementations. These implementations are not meant to limit the scope of coverage, but, instead, to assist in understanding the context of the language used in this specification and in the claims. Upon study of this disclosure and the exemplary implementations herein, one of ordinary skill in the art may readily recognize that various changes, modifications and variations can be made thereto without departing from the spirit and scope of the inventions as defined in the following claims.
