Dome stormwater chamber
This disclosure relates generally to stormwater management and, more particularly, to a stormwater chamber with a continuous curvature. The stormwater chamber may comprise a chamber body with a chamber wall, an apex, a base, and a first and second opening. The chamber wall may include a continuous curvature from the apex of the chamber body to the first and second openings and a continuous curvature from the apex of the chamber body to the base.
1. A chamber, comprising:
a chamber body including a chamber wall, an apex, a base, a first opening, and a second opening, a first coupling structure integral to the chamber body and positioned around the first opening and a second coupling structure integral to the chamber body and positioned around the second opening;
wherein the chamber wall includes a continuous curvature from the apex of the chamber body to the first and second openings and a continuous curvature from the apex of the chamber body to the base, the height of each of the first and second openings is less than half of a height of the chamber body;
wherein the chamber body includes more than one crest corrugation and more than one valley corrugation extending from the base toward the apex of the chamber body; and
wherein each of the first coupling structure and the second coupling structure includes an end corrugation and a body corrugation.
2. The chamber of claim 1 , wherein the base curves outward in a horizontal direction from the first and second coupling structures.
3. The chamber of claim 1 , wherein a cross-sectional shape of the chamber body along a horizontal plane above the first and second coupling structures is substantially circular.
4. The chamber of claim 1 , wherein a cross-sectional shape of the chamber body along a horizontal plane above the first and second coupling structures is substantially elliptical.
5. The chamber of claim 1 , wherein the crest corrugations and valley corrugations are evenly spaced around the base.
6. The chamber of claim 1 , wherein the width of the crest corrugations remains constant with increasing elevation from the base.
7. The chamber of claim 1 , wherein the width of the valley corrugations decreases with increasing elevation from the base.
8. The chamber of claim 1 , wherein the depth of the crest corrugations and valley corrugations decreases with increasing elevation from the base.
9. The chamber of claim 1 , wherein the valley corrugations terminate at an elevation below the apex of the chamber body.
10. The chamber of claim 1 , wherein the crest corrugations include crest sub-corrugations.
11. The chamber of claim 10 , wherein the width and depth of the crest sub-corrugations decrease with increasing elevation from the base.
12. The chamber of claim 1 , wherein the valley corrugations include valley sub-corrugations.
13. A stormwater management system, comprising:
at least two chambers coupled together, each chamber including:
a chamber body having a chamber wall, an apex, a base, a first opening, and a second opening, a first coupling structure integral to the chamber body and positioned around the first opening and a second coupling structure integral to the chamber body and positioned around the second opening, wherein one of the first and second coupling structures of a first chamber is directly coupled to one of the first and second coupling structures of a second chamber;
wherein the chamber wall includes a continuous curvature from the apex of the chamber body to the first and second openings and a continuous curvature from the apex of the chamber body to the base, and the chamber body includes more than one crest corrugation and more than one valley corrugation extending from the base toward the apex of the chamber body; and
wherein the first coupling structure and the second coupling structure each includes an end corrugation and a body corrugation.
14. The stormwater management system of claim 13 , further comprising at least two rows of chambers arranged adjacent to each other.
15. The stormwater management system of claim 13 , wherein the end corrugation and the body corrugation of the second coupling structure of the first chamber overlaps the end corrugation and the body corrugation of the first coupling structure of the second chamber.
16. The stormwater management system of claim 13 , wherein the end corrugation of the second coupling structure of the first chamber overlaps the end corrugation of the first coupling structure of the second chamber.
17. The stormwater management system of claim 13 , further comprising an endcap coupled to the first coupling structure of the first chamber.
18. A chamber comprising:
a chamber body including a chamber wall, an apex, a base, a first opening, and a second opening;
a first coupling structure positioned around the first opening, a second coupling structure positioned around the second opening, the first coupling structure integral to the chamber body and positioned around the first opening and the second coupling structure integral to the chamber body and positioned around the second opening, a height of each of the first and second openings is less than half of a height of the chamber body;
wherein the chamber wall includes a continuous curvature from the apex of the chamber body to the base; the chamber body includes more than one crest corrugation and more than one valley corrugation extending from the base toward the apex of the chamber body; each of the first coupling structure and second coupling structure includes an end corrugation and a body corrugation; and the base curves outward in a horizontal direction from the first and second coupling structures.
