Abstract

Precast utility enclosure aprons for buried utility enclosures that have an angled top surface to direct water, ice and debris away from the center of the apron and to limit damage to the apron and utility enclosure caused by impacts to the apron.

First claim

What is claimed is:

1. A utility enclosure apron comprising a looped member configured to be mounted around a perimeter of a utility enclosure and having a lightweight material encased within a concrete material such that the lightweight material is surrounded on all sides by the concrete material, the looped member having a top surface, a bottom surface, an outer edge between the top surface and the bottom surface, a center opening and an inner edge between the top surface and the bottom surface around the center opening.

2. The utility enclosure apron according to claim 1 , wherein the lightweight material comprises a lightweight foam.

3. The utility enclosure apron according to claim 2 , wherein the lightweight foam comprises a foam pad or a foam block.

4. The utility enclosure apron according to claim 1 , wherein the lightweight material is encased within the looped member adjacent the bottom surface.

5. The utility enclosure apron according to claim 1 , wherein the lightweight material is encased within the looped member along the entire looped member or partially along the looped member.

6. The utility enclosure apron according to claim 1 , wherein the top surface is tapered from the inner edge to the outer edge.

7. The utility enclosure apron according to claim 6 , wherein an angle of the taper is between about 3 degrees and about 15 degrees.

8. The utility enclosure apron according to claim 1 , wherein the concrete material comprises one of solid concrete, polymer concrete, or polymer concrete reinforced with fiberglass.

9. A utility enclosure kit comprising:
a utility enclosure configured for underground installation; and
a utility enclosure apron configured to be positioned to surround a top surface of the utility enclosure, the apron including:
a looped member having a lightweight material encased within a concrete material such that the lightweight material is surrounded on all sides by the concrete material, the looped member having a top surface, a bottom surface, an outer edge between the top surface and the bottom surface, a center opening and an inner edge between the top surface and the bottom surface around the center opening.

10. The utility enclosure kit according to claim 9 , wherein the lightweight material comprises a lightweight foam.

11. The utility enclosure kit according to claim 10 , wherein the lightweight foam comprises a foam pad or a foam block.

12. The utility enclosure kit according to claim 9 , wherein the lightweight material is encased within the looped member adjacent the bottom surface.

13. The utility enclosure kit according to claim 9 , wherein the lightweight material is encased within the looped member along the entire looped member or partially along the looped member.

14. The utility enclosure kit according to claim 9 , wherein the top surface is tapered from the inner edge to the outer edge.

15. The utility enclosure kit according to claim 14 , wherein an angle of the taper is between about 3 degrees and about 15 degrees.

16. The utility enclosure kit according to claim 9 , wherein the concrete material comprises one of, solid concrete, polymer concrete or a polymer concrete reinforced with fiberglass.

17. A utility enclosure apron comprising a looped member having a lightweight filler material encased within polymer concrete reinforced with fiberglass so that the lightweight filler material is surrounded on all sides by the polymer concrete reinforced with fiberglass, the looped member having a top surface, a bottom surface, an outer edge between the top surface and the bottom surface, a center opening and an inner edge between the top surface and the bottom surface around the center opening, the top surface being tapered from the inner edge to the outer edge.

18. The utility enclosure apron according to claim 17 , wherein the lightweight filler material comprises a lightweight foam.

19. The utility enclosure apron according to claim 18 , wherein the lightweight foam comprises a foam pad or a foam block.

20. The utility enclosure apron according to claim 17 , wherein an angle of the taper is between about 3 degrees and about 15 degrees.
