Leaching chamber having a diagonally ribbed top
View Patent ↗A leaching chamber having opposing inwardly and upwardly running sidewalls extending toward a top portion is provided, wherein the leaching chamber includes a plurality of peak and valley corrugations formed by the sidewalls and extending over the top portion and a plurality of diagonally opposed ribs, the plurality of ribs extending diagonally across at least a portion of the top portion to form at least one X shaped pattern.
1. A leaching chamber having opposing inwardly and upwardly running sidewalls extending toward a top portion to form a plurality of peak and valley corrugations extending over the top portion, the leaching chamber comprising:
a plurality of diagonally opposed ribs, wherein the plurality of diagonally opposed ribs are located in the valleys of the top portion and include a first rib extending in one direction diagonally across a part of the top portion between the peak corrugations on each side of the valley and a second rib extending diagonally across a part of the top portion in a direction that is a mirror of the direction of the first rib between the peak corrugations on each side of the valley to form an X shaped pattern across said part of the top portion in the valley, wherein said part of the top portion in the valley is free of any ribs extending along a lengthwise direction of the leaching chamber.
2. The leaching chamber of claim 1 , wherein the first rib and second rib intersect in a center area of the top portion.
3. The leaching chamber of claim 1 , wherein the inwardly and upwardly curving sidewalls connect at the top of the chamber to form the top portion and wherein the top portion is curved.
4. The leaching chamber of claim 1 , wherein the inwardly and upwardly running sidewalls are planar and connect to a top portion at the top of the chamber.
5. The leaching chamber of claim 1 , wherein the plurality of ribs have a height of about 0.2 inches and a width of about 0.7 inches.
6. The chamber of claim 1 , wherein the ribs extend at least one of upwardly and downwardly from the surface of the top portion.
7. An arch shaped cross section chamber, for use in receiving and dispersing wastewater or storm-water within soil, having corrugations comprised of a multiplicity of alternating peaks and valleys which run transversely to the length of the chamber, comprising:
opposing sidewalls running inwardly and upwardly towards a top of the chamber from opposing side base flanges, wherein the top of the chamber connects the upper portions of the opposing sidewalls; and
a plurality of ribs running across a portion of the tops of the valleys, each rib lying in a vertical plane which runs diagonally relative to the vertical lengthwise center plane of the chamber to form an X shaped pattern of ribs across said portion of the tops of the valleys such that
a first X shaped pattern of ribs is located on one side of the valley relative to a longitudinal center plane extending along a lengthwise direction of the leaching chamber, and
a second X shaped pattern of ribs is located on the opposing side of the valley relative to the longitudinal center plane extending along a lengthwise direction of the leaching chamber,
wherein the surface of the valley located between the first X shaped pattern of ribs and the second X shaped pattern of ribs is free of an upwardly projecting structure running between the peak on one side of the valley to the peak on the opposing side of the valley.
8. The chamber of claim 7 , wherein the plurality of ribs include a first rib extending in one direction diagonally across the top of the valley and a second rib extending diagonally across the top of the valley in a direction that is a mirror of the direction of the first rib to form at least one X shaped pattern.
9. The chamber of claim 8 , wherein the first and second ribs intersect in a center area of said portion of the tops of the valleys.
10. The chamber of claim 7 , wherein the plurality of ribs extend across at least a portion of the top of the valley between the peak corrugations to form a plurality of X shaped patterns.
11. The chamber of claim 7 , wherein the inwardly and upwardly running sidewalls connect at the top of the chamber to form the top portion and wherein the sidewalls and top portion is curved.
12. The chamber of claim 7 , wherein the inwardly and upwardly running sidewalls are planar.
13. The chamber of claim 7 , wherein the plurality of ribs have a height of about 0.2 inches and a width of about 0.7 inches.
14. The chamber of claim 7 , wherein the ribs extend at least one of upwardly and downwardly from the surface of the top of the valleys.
15. A chamber comprised of peak and valley corrugations and having a base, a top portion, and opposing sidewalls running inwardly and upwardly from the base to the top portion, comprising:
a plurality of diagonally opposed ribs located in at least one of the peak and valley corrugations at the top portion of the chamber, the plurality of ribs extending diagonally across at least a portion of the top portion to form an X shaped pattern across said portion of the top portion, wherein said portion of the top portion is free of any ribs extending along a lengthwise direction of the chamber.
16. The chamber of claim 15 , wherein the plurality of ribs are located in the valley of the top portion and include a first rib extending in one direction diagonally across the top portion between the peak corrugations on each side of the valley and a second rib extending diagonally across the top portion in a direction that is a mirror of the direction of the first rib between the peak corrugations on each side of the valley to form at least one X shaped pattern.
17. An arch shaped cross section chamber, for use in receiving and dispersing wastewater or storm-water within soil, having corrugations comprised of a multiplicity of alternating peaks and valleys which run transversly to the length of the chamber, comprising:
opposing sidewalls running inwardly and upwardly towards a top of the chamber from opposing side base flanges, wherein the top of the chamber connects the upper portions of the opposing sidewalls; and
a plurality of ribs running across a portion of the tops of the valleys, each rib lying in a vertical plane which runs diagonally relative to the vertical lengthwise center plane of the chamber to form an X shaped pattern of ribs across said portion of the tops of the valleys such that
a first X shaped pattern of ribs is located on one side of the valley relative to a longitudinal center plane extending along a lengthwise direction of the leaching chamber, and
a second X shaped pattern of ribs is located on the opposing side of the valley relative to a longitudinal center plane extending along a lengthwise direction of the leaching chamber,
wherein the surface of the valley located between the first X shaped pattern of ribs and the second X shaped pattern of ribs is free of an X shaped pattern of ribs or a circular spot.
