Abstract

An underground service protection system made from two main sections, a first frame having a bottom panel with hinged side and end panels and a second frame having side and end panels. The end panels retain inserted slides having half apertures. The half apertures surround a pipe or other structure being protected while the first frame and second frame form a protective cage. A standpipe and a back-fill gauge extend upward from the protection system. The hinged ends and sides enable the first frame to be installed with reduced material removable. The first frame and the second frame are aligned and held together using stakes on the first frame and pockets on the second frame. Tie wraps are used to hold the sides and the stakes and pockets together.

Claims

1. An underground service protection system, comprising:

a first frame having a bottom panel, a first side panel attached to said bottom panel by a first hinge, a second side panel attached to said bottom panel by a second hinge, a first end panel attached to said bottom panel by a third hinge, and a second end panel attached to said bottom panel by a fourth hinge, wherein said first end panel includes a first set of insert slides and said second end panel includes a second set of insert slides;

a second frame having a top panel, a third side panel, a fourth side panel, a third end panel, and a fourth end panel wherein said third end panel includes a third set of insert slides and said fourth end panel includes a fourth set of insert slides;

a first insert having a first half aperture inserted into said first set of insert slides;

a second insert having a second half aperture inserted into said second set of insert slides;

a third insert having a third half aperture inserted into said third set of insert slides; and

,

a fourth insert having a fourth half aperture inserted into said fourth set of insert slides;

wherein said first frame and said second frame are aligned such that said first half aperture and said third half aperture form a first aperture and said second half aperture and said fourth half aperture form a second aperture.

2. The underground service protection system of claim 1, further including a first collar attached to said top panel and a standpipe extending upward from said first collar.

3. The underground service protection system of claim 2, further including a pipe cover over said standpipe and a lock system for locking said pipe cover to said standpipe.

4. The underground service protection system of claim 2, wherein said standpipe extends above ground and includes indicia with information regarding the underground service protection system.

5. The underground service protection system of claim 2, wherein said standpipe extends above ground and is color coded to provide information regarding the underground service protection system.

6. The underground service protection system of claim 2, further including a second collar attached to said top panel and a backfill gauge extending upward from said second collar.

7. The underground service protection system of claim 6, wherein said backfill gauge indicates how much backfill material is needed to cover the underground service protection system.

8. The underground service protection system of claim 1, wherein said first aperture and said second aperture fit over a pipe.

9. The underground service protection system of claim 1, wherein said first hinge includes a hinge pin passing through said bottom panel.

10. The underground service protection system of claim 1, wherein said first frame includes stakes, wherein said second frame includes pockets, and wherein said stakes fit into said pockets when said first frame and said second frame are aligned.

11. The underground service protection system of claim 10, wherein said stakes and pockets are secured together by tie wraps.

12. The underground service protection system of claim 1, wherein said first side panel and said second side panel are secured together by tie wraps.

13. The underground service protection system of claim 1, wherein said first frame and said second frame form a protective cage around a pipe.

14. The underground service protection system of claim 1, wherein said first panel is comprised of a structural framework of square cross-sectional elements interconnected by a series of open lattice panels.

15. The underground service protection system of claim 1, wherein said second frame is a rigid structure.

16. The underground service protection system of claim 15, wherein said second frame is made using an injection molding process.

17. A protection system, comprising:

a first frame having a bottom panel, a first side panel attached to said bottom panel by a first hinge, a second side panel attached to said bottom panel by a second hinge, a first end panel attached to said bottom panel by a third hinge, and a second end panel attached to said bottom panel by a fourth hinge, wherein said first end panel includes a first set of insert slides and said second end panel includes a second set of insert slides;

a second frame having a top panel, a third side panel, a fourth side panel, a third end panel, and a fourth end panel wherein said third end panel includes a third set of insert slides and said fourth end panel includes a fourth set of insert slides;

a first insert having a first half aperture inserted into said first set of insert slides;

a second insert having a second half aperture inserted into said second set of insert slides;

a third insert having a third half aperture inserted into said third set of insert slides; and

,

a fourth insert having a fourth half aperture inserted into said fourth set of insert slides;

wherein said first frame and said second frame are aligned such that said first half aperture and said third half aperture form a first aperture and said second half aperture and said fourth half aperture form a second aperture;

a first collar attached to said top panel;

a second collar attached to said top panel;

a third collar attached to said bottom panel; and

,

a fourth collar attached to said bottom panel.

18. The protection system of claim 17, further including a standpipe extending upward from said first collar and a pipe cover over said standpipe.

19. The protection system of claim 17, further including a backfill gauge extending from said second collar.

20. The protection system of claim 17, wherein said first frame includes stakes, wherein said second frame includes pockets, and wherein said stakes fit into said pockets when said first frame and said second frame are aligned.
