Abstract

Stormwater management systems, methods, and apparatuses for containing and filtering runoff may be provided. In one implementation, a flared end ramp for managing flow of material into a stormwater chamber may be provided. The flared end ramp may include an inlet end configured for connection with a pipe, a side wall of the flared end ramp having a rounded profile at the inlet end; an outlet end configured for placement within the stormwater chamber; and an inclined surface extending between the inlet end and the outlet end of the flared end ramp and configured to deliver material from the pipe into the stormwater chamber. The outlet end of the flared end ramp may have a larger width than the inlet end of the flared end ramp such that the inclined surface is angled laterally outward from the inlet end toward the outlet end.

First claim

What is claimed is:

1. A flared end ramp for managing flow of material into a stormwater chamber, the flared end ramp comprising:
an inlet end configured for connection with a pipe, a side wall of the flared end ramp having a rounded profile at the inlet end;
an outlet end configured for placement within the stormwater chamber; and
an inclined surface extending between the inlet end and the outlet end of the flared end ramp and configured to deliver material from the pipe into the stormwater chamber,
wherein the outlet end of the flared end ramp has a larger width than the inlet end of the flared end ramp such that the inclined surface is angled laterally outward from the inlet end toward the outlet end, and
wherein the inclined surface includes at least one drainage groove extending between the inlet end of the flared end ramp and the outlet end of the flared end ramp.

2. The flared end ramp of claim 1 , further comprising:
at least one support foot configured to support the flared end ramp, the at least one support foot being located at the outlet end of the flared end ramp and extending laterally from the flared end ramp.

3. The flared end ramp of claim 2 , wherein the flared end ramp includes a single support foot extending laterally between a first side of the outlet end and a second side of the outlet end, the single support foot forming the widest portion of the flared end ramp.

4. The flared end ramp of claim 2 , wherein the at least one support foot is configured to secure the flared end ramp relative to the stormwater chamber.

5. The flared end ramp of claim 1 , wherein the stormwater chamber is an open-bottom chamber or a cylindrical pipe.

6. The flared end ramp of claim 1 , wherein the side wall of the flared end ramp has a semi-circular profile or an annular profile at the inlet end.

7. The flared end ramp of claim 1 , wherein at the outlet end of the flared end ramp, the inclined surface includes a flattened bottom portion and first and second upstanding side portions.

8. The flared end ramp of claim 1 , wherein the at least one drainage groove includes:
a first drainage groove extending along a midline of the inclined surface; and
a second drainage groove angled laterally outward from the inlet end toward the outlet end.

9. The flared end ramp of claim 1 , wherein the inlet end of the flared end ramp is configured to receive an end of the pipe within the rounded profile of the inlet end.

10. The flared end ramp of claim 1 , wherein the inlet end of the flared end ramp is configured to conform to an outer surface of the pipe.

11. The flared end ramp of claim 1 , wherein the inlet end of the flared end ramp is configured for placement within the stormwater chamber.

12. The flared end ramp of claim 1 , wherein the flared end ramp is configured to convey material away from an end cap of the stormwater chamber.

13. A flared end ramp and end cap apparatus for a stormwater chamber, the apparatus comprising:
a flared end ramp comprising an inlet end configured for connection with a pipe, an outlet end configured for placement within the stormwater chamber, and an inclined surface extending between the inlet end of the flared end ramp and the outlet end of the flared end ramp, the inclined surface configured to deliver material from the pipe into the stormwater chamber; and
a stormwater chamber end cap having an interior surface configured to delimit a chamber enclosure formed by the stormwater chamber and the end cap.

14. The apparatus of claim 13 , wherein the stormwater chamber is an open-bottom chamber or a cylindrical pipe.

15. The apparatus of claim 13 , wherein the outlet end of the flared end ramp has a larger width than the inlet end of the flared end ramp such that the inclined surface is angled laterally outward from the inlet end toward the outlet end.

16. The apparatus of claim 13 , wherein the flared end ramp further comprises:
at least one support foot located at the outlet end of the flared end ramp and extending laterally from the flared end ramp, wherein the at least one support foot is configured to secure the flared end ramp relative to the stormwater chamber.

17. The apparatus of claim 13 , wherein at the outlet end of the flared end ramp, the inclined surface includes a flattened bottom portion and first and second upstanding side portions.

18. The apparatus of claim 13 , wherein the flared end ramp and the end cap are configured to be secured together by the pipe.

19. The apparatus of claim 13 , wherein
the end cap includes at least one opening configured to receive the pipe, and
the flared end ramp is configured for placement within the stormwater chamber.
