Example embodiments in general relate to an integrated access box for providing access to both line tracer wires and curb boxes used to access curb stop valves.
Any discussion of the related art throughout the specification should in no way be considered as an admission that such related art is widely known or forms part of common general knowledge in the field.
Curb stop valves, accessible through curb boxes with grade-level lids, have been in use for many years for allowing people to shut off individual water supplies (between a city water main and a house, for example) using a curb stop valve, also known as simply a curb stop. In addition, usually near but separate from the curb box access location, some cities employ trace wires in order to locate the underground water service lines and water mains by injecting an electrical signal to the wires that are buried near the lines and mains for that purpose. However, tracer wire access requires a separate access box (e.g. see
An example embodiment is directed to an integrated access box. The integrated access box includes a body having a first end and a second end, a first chamber (e.g., a curb box chamber) extending into the first end toward the second end of the body. The body of the integrated access box may be substantially cylindrical in shape, or comprise a substantially cylindrical portion, and may specifically be elongated, having a length greater than its diameter, although other shapes are possible. If it is in the shape of an elongated cylinder, the body of the integrated access box may comprise a body in the shape of a cylinder extending from the first end to the second end, wherein each end is a cylinder end.
The curb box chamber may further comprise a first opening proximate the first end of the body. The integrated access box may also include a curb stop access opening in the curb box chamber proximate the second end of the body, and a tracer wire chamber extending into the first end toward the second end of the body, the tracer wire chamber further comprising a second opening proximate the first end of the body, wherein the tracer wire chamber may be isolated from the curb box chamber by the body. The example embodiment may further include a tracer wire access opening in the tracer wire chamber proximate the second end of the body.
In the example integrated access box, the curb stop access opening may comprise a threaded opening to accept a threaded lid. Further, in some example embodiments, the curb box chamber may be substantially in the shape of an elongated cylinder extending from the first end toward the second end, and the curb box chamber may be sized to slidably or frictionally engage a curb box. The body may also comprise a top proximate the second end, and the curb stop access opening in the curb box chamber may comprise an opening in the top which may be, for example, a threaded opening adapted to accept a threaded lid. In addition, the tracer wire access opening can comprise an opening in the top, and the opening may include a terminal box sized and shaped to be removably positioned in the tracer wire access opening, the terminal box comprising a plurality of tracer wire terminals.
In still further example embodiments, the body may comprise a flange that extends beyond the cylindrical portion of the body. The flange may be in the form of a ring-shaped extension at or near the bottom of the body, but may also be formed at other locations, and still serve the purpose of anchoring the integrated access box in the ground.
In another example embodiment, the integrated access box may comprise a body having a first end and a second end, and also a means for mounting the integrated access box on a curb box. The means for mounting may include, but is not limited to, a curb box chamber, such as a substantially cylindrical chamber within the body, extending into the first end toward the second end of the body. The integrated access box in this embodiment may also comprise means proximate the second end of the body for accessing a curb box to adjust a curb stop valve.
This example embodiment may further comprise means proximate the second end of the body for accessing tracer wires. The means may include, but is not limited to, a tracer wire chamber extending into the first end toward the second end of the body, the tracer wire chamber further comprising a second opening proximate the first end of the body, wherein the tracer wire chamber may be isolated from the curb box chamber by the body. The example embodiment may further include a tracer wire access opening in the tracer wire chamber proximate the second end of the body.
In another example embodiment, the integrated access box may be used in conjunction with a sewer cleanout pipe, rather than a curb box. The structure of the embodiment can be similar to the curb box embodiment, although the size and material may be different. For example, the first chamber (similar to the curb box chamber) may be referred to as a cleanout chamber, which may be sized and shaped to fit closely on a riser, rather than a curb box.
The first chamber may further comprise a first opening proximate the first end of the body. The integrated access box may also include a first chamber access opening in the first chamber proximate the second end of the body, and a tracer wire chamber extending into the first end toward the second end of the body, the tracer wire chamber further comprising a second opening proximate the first end of the body, wherein the tracer wire chamber may be isolated from the first chamber (e.g., the cleanout chamber) by the body. The example embodiment may further include a tracer wire access opening in the tracer wire chamber proximate the second end of the body.
In the example integrated access box, the first chamber access opening may comprise a threaded opening to accept a threaded lid. Further, in some example embodiments, the first chamber or cleanout chamber may be substantially in the shape of an elongated cylinder extending from the first end toward the second end, and the first chamber may be sized to closely engage a curb box. Further, the integrated access box may be made of PVC so that the inner walls of the first chamber can be glued to a PVC riser pipe, with the first chamber being sized to exactly or very closely match the outside diameter of the riser pipe. The body may also comprise a top proximate the second end, and the first chamber access opening in the first chamber may comprise an opening in the top which may be, for example, a threaded opening adapted to accept a threaded lid. In addition, the tracer wire access opening can comprise an opening in the top, and the opening may include a terminal box sized and shaped to be removably positioned in the tracer wire access opening, the terminal box comprising a plurality of tracer wire terminals.
There has thus been outlined, rather broadly, some of the embodiments of the integrated access box in order that the detailed description thereof may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional embodiments of the integrated access box that will be described hereinafter and that will form the subject matter of the claims appended hereto. In this respect, before explaining at least one embodiment of the integrated access box in detail, it is to be understood that the integrated access box is not limited in its application to the details of construction or to the arrangements of the components set forth in the following description or illustrated in the drawings. The integrated access box is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of the description and should not be regarded as limiting.
Example embodiments will become more fully understood from the detailed description given herein below and the accompanying drawings, wherein like elements are represented by like reference characters, which are given by way of illustration only and thus are not limitative of the example embodiments herein.
An example integrated access box 10 generally comprises a body 12 having a first end 14 and a second end 16, and a curb box chamber 20 extending into the first end 14 toward the second end 16 of the body. The body 12 of the integrated access box 10 may be substantially cylindrical in shape, or comprise a substantially cylindrical portion, and may specifically be elongated, having a length greater than its diameter, although other shapes are possible. If it is in the shape of an elongated cylinder, the body 12 of the integrated access box 10 may comprise a body in the shape of a cylinder extending from the first end 14 to the second end 16, wherein each end of the body is a cylinder end.
The curb box chamber 20 may further comprise a first opening 22 proximate the first end 14 of the body 12. The integrated access box 10 may also include a curb stop access opening 24 in the curb box chamber 20 proximate the second end 16 of the body 12, and may also include a tracer wire chamber 30 extending into the first end 14 toward the second end 16 of the body 12, the tracer wire chamber 30 further comprising a second opening 32 proximate the first end 14 of the body, wherein the tracer wire chamber 30 may be, but is not necessarily, isolated from the curb box chamber 20 by the body 12. The example embodiment may further include a tracer wire access opening 34 in the tracer wire chamber 30 proximate the second end 16 of the body 12, and the opening 34 may further be an opening in top 17.
The curb stop access opening 24 may accept a threaded curb stop lid 60. Further, in some example embodiments, the curb box chamber 20 may be substantially in the shape of an elongated cylinder extending from the first end of the body, 14, toward the second end 16, and the curb box chamber 20 may be sized to frictionally engage a curb box 70, which is a common term for the access pipe to a curb stop that is used to turn water off between a water main 42 and a house or building. In addition, the body 12 may further comprise a stop flange 18 that extends beyond the cylindrical portion of the body 12.
The body 12 may also comprise a top 17 proximate the second end 16, and the curb stop access opening 24 in the curb box chamber 20 may comprise an opening in the top 17 which may be, for example, a threaded opening adapted to accept a threaded lid 60. In addition, the tracer wire access opening 34 can comprise an opening in the top 17, and the opening may include a terminal box 50 sized and shaped to be removably positioned in the tracer wire access opening 34, the terminal box 50 comprising a plurality of tracer wire terminals 52 and screws 53.
The integrated access box 10 may also be used in conjunction with a sewer cleanout riser 82. This embodiment is shown in
In addition, while either application may comprise a body 12 made of various materials, such as composite, PVC, or even ductile iron, it may be advantageous to make the body of PVC, such as Schedule 40 IPS PVC pipe, that can be glued to a PVC riser 82, as shown for example in
Since sewer connections must be sealed, the cleanout embodiment will typically not have a stop flange 18, because the integrated access box 10 will not be allowed to “float” on riser pipe 82, but will instead be secured to it. The cleanout chamber 92 may have a cleanout first opening 96 at the first end 14 of body 12, and can also include a cleanout access opening (or first chamber access opening) 94 near the second end 16 of body 12.
The body 12 may also comprise a top 17 proximate the second end 16, and the cleanout access opening 94 in the cleanout chamber 92 may comprise an opening in the top 17 which may be, for example, a threaded opening adapted to accept a threaded lid 90. In addition, the tracer wire access opening 34 can comprise an opening in the top 17, and the opening 34 may include a terminal box 50 sized and shaped to be removably positioned in the tracer wire access opening 34, the terminal box 50 comprising a plurality of tracer wire terminals 52 and screws 53.
As discussed above, an example integrated access box 10 generally comprises a body 12 having a first end 14 and a second end 16. As shown in
The body 12 may be made of composite material, and may also have UV resistance added for long life even in direct sunlight. Other materials, such as PVC or ductile iron, may also be used. As best shown in
The integrated access box 10 is designed so that it can be installed on new or existing curb boxes 70 or riser pipes 82, which provide support for the integrated access box 10. However, the integrated access box 10 is not necessarily firmly mounted on the curb box 70. For example, the access box 10, and specifically, the curb box chamber 20, may be designed so that it will slide over and engage with a 1½″, 1¼″, or 2″ curb box 70. In the cleanout embodiment, the cleanout chamber 92 will be sized and shaped so that it will slide onto, and may be glued onto, a riser pipe 82. Other sizes and shapes for the integrated access box 10 or its chambers are also possible in order to accommodate curb boxes or pipes of various sizes, shapes, and materials used in different areas for curb stop valve access, cleanout access, etc. The curb box chamber 20 may be sized so that it frictionally engages the curb box 70, or it may be sized to more freely slide over the curb box 70.
As best shown in
The body 12 may also include a curb stop access opening 24 in the top 17 of the curb box chamber 20 near the second end 16 of the body 12. The opening 24 may be a circular, threaded opening which can accept a threaded curb stop lid 60, which allows secure access to the curb box 70 and the curb stop valve 72 that allows for water supply shutoff between the water main 42 and a house or building, as shown in
As shown in
If the body 12 is cylindrical, as shown, the tracer wire chamber 30 may be in the shape shown in
At the upper end or second end 16 of the integrated access box 10, the body 12 may include a top 17. The top 17 serves to keep dirt, objects, etc. out of the interior portion of the integrated access box 10. The top 17 also has openings for access to the curb box 70 and the tracer wires 54 from the surface. As shown in
To further facilitate this connection, and as required by some authorities, extra tracer wire may be coiled within the tracer wire chamber 30, as shown in
When the terminal box 50 is secured in the top of integrated access box 10, a lid 58 may be inserted or snapped in place to cover and protect the terminals 52, as shown in
Certain municipalities specify that there must be a tracer wire access box near each water service shutoff valve (i.e., curb stop valve), which is typically at ground level, between a house or building and the water main 42. The same requirement may exist for sewer service pipes. Access boxes (including access caps) are typically buried in the boulevard, or in each homeowner's yard. The integrated access box 10 will eliminate the need for two separate access boxes, and will slide over any existing or new curb box 70 or fit onto a riser pipe 82, and will typically include two tracer wire terminals 52, and a separate chamber 30 within the integrated access box 10 for tracer wire 54. The terminals 52 are used for connecting a line tracer to the tracer wires 54, with one wire being grounded by a grounding anode rod 74, and the other wire for carrying a tracer signal. The plan view of
The integrated access box 10 may be used to replace individual access boxes. With reference to
A similar configuration is shown in
As mentioned above, the integrated access box 10 can be used to replace and improve such conventional systems, or it can be used for new installations.
The integrated access box 10 eliminates the need for separate access boxes. As shown in
