This invention relates to temporary structures for filling with water for damming water courses, controlling and directing water flow, for damming between walls and support structures, and providing for end to end connection of structures to extend across an area to be dammed, and the like, and includes sleeves for containing water containing bladders, where the damming structure is inexpensive to construct, erect, and dismantle.
A need for easily installable and versatile water containment structure, and the like, particularly structures that are easily installed by filling them with water, that are relatively inexpensive, non-permanent, reusable and are durable, have been recognized by the inventor who has been awarded a number of U.S. patents for forming and joining water structures together, forming hydraulic water containment structures. Such water containment structures have been found to be very useful for safely and reliably containing water, for directing and controlling water, are also useful for controlling hazardous waste, oil or chemical spills, and the like. Further, such water containment structures are also useful, for example, for temporary damming operations, such as may be involved in agricultural water storage, construction, for de-watering work sites and fields, to protect buildings against flooding, and the like, and are even appropriate for use as permanent or long term water containment structures.
Heretofore it has been recognized that fluid filled flexible water containment structures and barriers can, if formed to resist movement, be used for retention and storage of water, control of water flow and as barriers against wave action, and a number of configurations of dams and barriers have been arranged as both semi-permanent and temporary structures. Such earlier patents, however, do not show a combination of a flexible sleeve that is configured with like finger ends, where the sleeves can be fitted and maintained together to form a continuous water containment structure, or where the finger ends can be fitted across a door way, or against a wall end, to span that door way or wall. In practice, with the filling of a bladder or bladders within the sleeve or sleeves, a secure water containment structure is formed.
Where earlier water containment sleeve and bladder structures have been arranged across an area to be dammed or de-watered, such have generally included pairs of sleeves with bladders that are braced against a pier structure, or have employed an outer sleeve to discourage the individual interior sleeves and filled bladders from rolling apart responsive to the weight of water or wave action that have been directed against the water containment structure, or have utilized other arrangements for keeping the sleeves with water filled bladders from moving. Unique to the invention, the sleeve fingers can be joined together, as by lacing them together along common edges, to discourage sleeve movement, can be joined around a fixed pole, or the like.
Summarizing, before the invention, no prior art water containment structure has provided a barrier arrangement or arrangements of barriers with the like sleeve ends have fingers to function, as set out above, to provide a versatile water containment structure that will meet a variety of needs as the invention can be used for.
It is a principal object of the present invention to provide a water containment structure that includes at least one flexible sleeve for containing a bladder or bladders for filling with water, where each bladder includes a filling arrangement and an air drain, and where the sleeve or sleeves have like finger ends separated by a center U shaped notch that the bladder or bladder ends fit into, and each said sleeve end includes an air vent for venting air during filling of the bladder or bladders with water, and the sleeve ends notches are arranged to be fitted together, alongside one another on opposite sides of the edge of a doorway or wall, to provide, when the bladder or bladders are filled with water, a barrier to contain, or block, a volume of water, and which sleeve notched ends, when fitted together where the opposing sides of each notch are in contact and can be maintained together to form a continuous barrier across an area to be de-watered, or protected from flood waters.
Another object of the present invention is to provide sleeve ends, from adjacent to the sleeve notches to finger ends, with flat parallel top and bottom surfaces, or can form each sleeve finger to have a taper in the top from adjacent to, or forward from, the notch, to the finger end to facilitate positioning of the sleeve finger ends, containing the bladder ends, across a door way or wall, and for, with blunt sleeve finger ends fitted together, provide approximately a uniform height of the water containment structure. across the notches.
Another object of the present invention is to provide sleeves having ends formed as fingers with a notch therebetween, where the finger ends can be fitted around or across a fixed structure such as a door way, wall, post, or the like, and provides for joining the sleeve fingers around such post, as by lacing the fingers ends through spaced holes formed along the notch and fingers edges, to fix the sleeve ends in place, whereafter, the bladder or bladders in the sleeve are filled with water to provide a barrier to water.
Still another object of the present invention is to provide for; conveniently filling each bladder with water to erect the structure as a water barrier; and provides for venting air from the bladder or bladders during filling; and for conveniently draining which bladder or bladders to deflate the barrier when it is no longer needed.
Still another object of the present invention is to provide a portable water containment structure that is easily transported and erected at a site to protect a building against flooding, prohibit flooding of an area, or for de-watering a flooded area, that is easily deflated and removed after the water danger has subsided.
Principal features of the invention include at least one sleeve that is formed from a strong, woven polypropylene material, such as GeoTex®, or like material, to provide a sleeve that is puncture resistant and has a tear strength that is sufficient to maintaining the forces exerted thereon when functioning as a water containment structure, and the sleeve is to receive at least one bladder that is preferably formed from a lightweight polyethylene material to have a capability to be filled with water to its capacity without rupturing. Which sleeve includes a filing tube of a length to rest on the bladder or bladders bottom, allowing the filling bladder or bladders contained within the sleeve with water, and which sleeve includes like notched sections in each end, and which end fingers are parallel and extend rearwardly from each notch such that the notch and finger form a U shape. The parallel fingers each receive a bladder end fitted therein to receive water, forming a water containment structure, and each sleeve finger end includes a vent port for venting air from the finger ends during bladder filling. In practice, the sleeve notched ends can each be fitted across opposite sides of a pair of wall ends or sides of a door opening, straddling that wall end or door way. Or which finger ends can be connected around a post. So arranged, the sleeve bladder or bladders, when filled with water, provide a water containing structure between the wall ends or across the doorway, or around a post, to prohibit waters from passing there across, and which sleeve sends of two sleeve can be connected end to end, as by laces, or the like, fitted through grommets formed at spaced intervals around the sleeve fingers edges and across the sleeve end notches, for joining end to end, forming a wall of connected sleeves forming a water containment structure.
The sleeve fingers top surface may be sloped relative to the finger bottom surface, from its junction with the end of the notch to the finger ends, to facilitate its fitting of the fingers along opposite sides of a doorway or wall sides, or the fingers may not be sloped within the scope of this disclosure. Each sleeve finger end configuration is blunt and includes an air vent formed therein, and the finger ends are essentially at right angles to the finger bottom surfaces, allowing the sleeve to be positioned together, end to end, at their notches for forming the continuous water containment structure, where the height of the joined sleeves, at their junction, will be essentially the same height as that of the filled sleeves. Additionally, the fingers ends can be joined around a pier or post and secured together, as by lacing, with the pier or post therebetween, providing an anchor for holding the sleeves in place.
In practice a strong flexible sleeve formed from GeoTex®, a material manufactured by Propex Operating Company, LLC, and bladder or bladders are formed from a lightweight polyethylene plastic, or the like, has been selected to provide a bladder that, when filled with water, is strong enough to resist punctures and the bladder ends, that fit into the sleeve finger ends, with each bladder or bladders preferably having a wall thickness of from (5) to (12) millimeters and is arranged for installation in the fabric sleeve of the invention prior to the bladder or bladders being filled with water. Though, it should be understood, the invention is not limited to any particular sleeve or bladder manufacture or thickness; can utilize sleeves and/or bladders of greater or lesser wall thickness; and the sleeve notch ends can be connected by lacing a lace cable through grommets formed in holes formed at spaced intervals along the junction of the sleeve top and bottom sections at the sleeve ends, or by other connection arrangement, for maintaining the sleeves fingers together, within the scope of this disclosure.
In the drawings which illustrate that which is presently regarded as the best mode for carrying out the invention:
Temporary water structures that are erected at a location to be de-watered, to protect an area or structure from anticipated flooding, and are in common use. Such temporary water structures have included flexible sleeves containing a bladder or a pair of bladders, shown as tubes, for positioning at a site to be dammed, with the bladder tubes then filled with water to erect the water containment structure. Heretofore, however, such water containment structures have lacked versatility in that none have provided convenient arrangements for joining sleeves together in an end to end relationship. Further, earlier temporary water structures have needed to included at least an arrangement of two bladders in a single sleeve, and, have often required end anchors, for anchoring the water structure ends, to anchor the water structure to provide a dam that would resist side ways movement, or rolling, from water forces exerted onto one side of the sleeve, or have required that a pair of sleeves with tubes or bladders in each that have then been contained in an outer sleeve to resist rolling movement where lateral forces were exerted against the structure. Whereas, the invention provides a sleeve 11 with finger ends 12 extending from ends of a U shaped center notch 13, forming parallel fingers 12, and, as appropriate for its use the sleeve 11 fingers 12 can be sloped to fit and be conveniently maintained across a door way or wall end, and provides for joining the sleeve fingers 13 ends together around a post, or the like, for anchoring the sleeve 11 ends 13 thereto. Also, a plurality of sleeves 11 each having blunt ends, that are approximately the height of the sleeve body, and can be joined end to end by fitting sleeve fingers 12 together at the sleeve notch 13 to form a water containment structure 10 that will resist movement.
Where the pair of bladder tubes 14a and 14b is shown herein as preferred, it should be understood that a single bladder, formed to fit within the sleeve 11 with ends therein fitted into the sleeve fingers 12, that includes a single fill tube 15a and 15b with nozzle end 16a and 16b and includes air drains 17a and 17b, could be used in the invention, within the scope of this disclosure. Additionally, air vents 18 are provided in the end of each sleeve finger 12 to facilitate venting air from the sleeve ahead of the bladder tubes 14a and 14b when the bladder tubes 14a and 14b are being filled with water through the fill tubes 15a and 15b. In practice, air vents 18 allow the bladder tubes 14a and 14b ends to fully fill the sleeve 11 and sleeve fingers 12 as the bladder tubes 14a and 14b are being filled with water.
