Abstract

A flared end ramp for managing and distributing fluid runoff. The flared end ramp may have an inlet end configured to connect to a pipe, a plurality of protrusions on the upper side of the inlet end, and an outlet end. An inclined surface may extend between the inlet end and the outlet end of the flared end ramp, 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. The flared end ramp may include a tab positioned on an edge of the outlet end, the tab extending vertically relative to the outlet end. The flared end ramp may be placed inside a stormwater chamber, and the tab may be positioned outside of the stormwater chamber.

Claims (29)

1 . A flared end ramp comprising:

an inlet end configured to connect to a pipe;

a plurality of protrusions extending upwardly from an upper side of the inlet end, wherein the plurality of protrusions are configured to be connected directly to each other to secure the pipe to the inlet end;

an outlet end;

an inclined surface extending between the inlet end and the outlet end of the flared end ramp, wherein the inclined surface is inclined relative to a ground on which the outlet end of the end ramp is positioned and 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;

at least one support foot extending laterally from the outlet end;

a first tab positioned on an edge of the at least one support foot, the first tab extending vertically upward relative to the at least one support foot, wherein the first tab is configured to prevent the flared end ramp from shifting in a lateral direction when the flared end ramp is placed partially within a stormwater management chamber with the inclined surface fully inside the stormwater management chamber and the first tab fully outside the stormwater management chamber.

2 . The flared end ramp of claim 1 , further comprising a fastener configured to connect the protrusions on the upper side of the inlet end to each other, thereby securing the flared end ramp to the pipe.

3 . The flared end ramp of claim 2 , wherein the fastener is a threaded rod or one or more zip ties.

4 . The flared end ramp of claim 1 , further comprising a second tab positioned on the at least one support foot, the second tab extending vertically relative to the at least one support foot, wherein the first tab and the second tab are positioned on opposite ends of the at least one support foot.

5 . The flared end ramp of claim 1 , further comprising an indent on the inlet end configured to prevent the pipe from sliding towards the outlet end.

6 . The flared end ramp of claim 5 , wherein the indent is rounded with a curvature corresponding to a radius of the pipe and wherein the indent protrudes upward from the upper side of the inlet end to a distance that is level with an inside diameter of the pipe.

7 . The flared end ramp of claim 1 , wherein the inclined surface includes at least one drainage channel extending between the inlet end of the flared end ramp and the outlet end of the flared end ramp, the drainage channel angled laterally outward from the inlet end toward the outlet end.

8 . The flared end ramp of claim 1 , wherein the flared end ramp is configured to be placed partially inside the stormwater chamber such that the at least one support foot is positioned partially outside of the stormwater chamber.

9 . A flared end ramp comprising:

an inlet end configured to connect to a pipe;

a plurality of protrusions extending upwardly from an upper side of the inlet end, wherein the plurality of protrusions are configured to be connected directly to each other to secure the pipe to the inlet end;

an outlet end;

an inclined surface extending between the inlet end and the outlet end of the flared end ramp, 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;

at least one support foot extending laterally from the outlet end; and

a first tab positioned on an outer end of the at least one support foot and extending vertically upward relative to the support foot, wherein the first tab is configured to prevent the flared end ramp from shifting in a lateral direction when the flared end ramp is placed partially within a stormwater management chamber with the inclined surface fully inside the stormwater management chamber and the first tab fully outside the stormwater management chamber.

10 . The flared end ramp of claim 9 , further comprising a fastener configured to connect the protrusions on the upper side of the inlet end to each other, thereby securing the flared end ramp to the pipe.

11 . The flared end ramp of claim 10 , wherein the fastener is a threaded rod or one or more zip ties.

12 . The flared end ramp of claim 9 , further comprising a second tab positioned on the at least one support foot, the second tab extending vertically relative to the at least one support foot, wherein the first tab and the second tab are positioned on opposite ends of the at least one support foot.

13 . The flared end ramp of claim 9 , further comprising an indent on the inlet end configured to prevent the pipe from sliding towards the outlet end.

14 . The flared end ramp of claim 13 , wherein the indent is rounded with a curvature corresponding to a radius of the pipe and wherein the indent protrudes upward from the upper side of the inlet end to a distance that is level with an inside diameter of the pipe.

15 . The flared end ramp of claim 9 , wherein the inclined surface includes at least one drainage channel extending between the inlet end of the flared end ramp and the outlet end of the flared end ramp, the drainage channel angled laterally outward from the inlet end toward the outlet end.

16 . The flared end ramp of claim 9 , wherein the flared end ramp is configured to be placed partially inside the stormwater management chamber such that the at least one support foot is positioned partially outside of the stormwater management chamber.

17 . The flared end ramp of claim 9 , wherein the support foot extends laterally relative to a longitudinal direction between the inlet end and the outlet end and extends beyond the width of the outlet end.
