Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

[ EN ]

What is claimed is:

1. A water detention and release system comprising:

a first concrete galley having:

a first top deck having a first side edge and a second side edge opposite the first side edge;

a first side wall extending from the first side edge substantially perpendicular to the first top deck; and

a second side wall extending from the second side edge substantially perpendicular to the first top deck;

a second concrete galley having:

a second top deck having a third side edge and a fourth side edge opposite the third side edge;

a third side wall extending from the third side edge substantially perpendicular to the second top deck; and

a fourth side wall extending from the fourth side edge substantially perpendicular to the second top deck;

the second galley being positioned substantially parallel to and a distance apart from the first galley such that the second and third side walls define a longitudinal channel between the first and second galleys; and

a cap spanning the longitudinal channel to form a chamber, the cap having an arch-shaped top portion and two side base portions for positioning the cap on the first and second galleys, each side base portion comprising a horizontal strut extending laterally away from the top portion and a vertical strut extending downwardly away from the top portion.

2. The water detention and release system of claim 1 , wherein the cap is a plastic material and a first side base portion conforms to the second side edge of the first galley and a second side base portion conforms to the third side edge of the second galley to position the cap on the first and second galleys.

3. The water detention and release system of claim 1 , wherein the cap further comprises a plurality of perforations distributed across the top portion.

4. The water detention and release system of claim 1 , wherein the cap further comprises a plurality of reinforcing members extending transverse to a longitudinal axis of the cap.

5. The water detention and release system of claim 1 , wherein the cap further comprises a slot on an upper surface of a first end of the cap, and a corresponding lip on a lower surface of a second end of the cap such that the slot of a first cap can interlock with the lip of a second matching cap to retain the first end of the first cap to the second end of the second matching cap.

6. The water detention and release system of claim 1 , wherein each of the side walls of the first and second galleys has at least one opening defining at least one lateral channel in the module.

7. The water detention and release system of claim 1 , further comprising: a third concrete galley having a third top deck having a fifth side edge and a sixth side edge; a fifth side wall extending from the fifth side edge substantially perpendicular to the third top deck; a sixth side wall extending from the sixth side edge substantially perpendicular to the third top deck; the third galley being positioned substantially parallel to and a distance apart from the second galley such that the fourth and fifth side walls define a second longitudinal channel between the second and third galleys; and

a second plastic cap spanning the second longitudinal channel to form a second chamber, the second cap having an arch-shaped top portion and two side base portions for positioning the cap on the second and third galleys.

8. The water detention and release system of claim 7, wherein each side base portion of the second cap comprises a horizontal strut and a vertical strut extending away from the top portion such that a third side base portion conforms to the fourth side edge of the second galley and a fourth side base portion conforms to the fifth side edge of the third galley to position the cap on the second and third galleys.

9. The water detention and release system of claim 8, wherein the second cap further comprises a plurality of perforations distributed across the top portion.

10. The water detention and release system of claim 8, wherein the second cap further comprises a plurality of reinforcing members extending transverse to a longitudinal axis of the cap.

1 1. The water detention and release system of claim 8, wherein the second cap further comprises a slot on an upper surface of a first end of the second cap, and a corresponding lip on a lower surface of a second end of the second cap.

12. A plastic cap for a water detention and release system comprising: a top portion having two sides and an upwardly extending arch shape between the two sides;

a base portion located at each of the two sides of the top portion, each base portion having a horizontal strut extending laterally away from the top portion and a vertical strut extending downwardly from the top portion;

a plurality of reinforcing members extending downwardly from the arch shaped top portion and transversely to a longitudinal axis of the cap.

13. The plastic cap of claim 12, wherein the cap further comprises a slot on one surface of the top portion at a first end of the cap, and a lip on an

opposite surface of the top portion of a second end of the cap, said lip being adapted to fit into the slot.

14. The plastic cap of claim 13, wherein the slot is open to and provided on an upper surface of the top portion at the first end of the cap, and the lip is provided on and extends downwardly from a lower surface of the top portion at the second end of the cap, said lip being adapted to fit into the slot.

15. The plastic cap of claim 12, further comprising a plurality of

perforations distributed across the arch-shaped top portion.

16. A method of providing a water detention and release system

comprising:

placing a first concrete galley having a first top deck and first and second downwardly-extending side walls in a excavated worksite;

placing a second concrete galley having a second top deck and third and fourth downwardly-extending side walls in the excavated worksite

substantially parallel to and a distance apart from the first galley to provide a longitudinal channel between the first and second galleys; and

placing a cap having an arch-shaped top portion and two side base portions, each side base portion having a horizontal strut extending laterally away from the top portion and a vertical strut extending downwardly from the top portion, over the longitudinal channel by positioning the horizontal struts of the side base portions on the first and second galleys, thereby forming a chamber.

17. The method of claim 16, further comprising placing a second cap having an arch-shaped top portion and two side base portions, each side base portion having a horizontal strut extending laterally away from the top portion and a vertical strut extending downwardly from the top portion, over the longitudinal channel by positioning the horizontal struts of the side base portions on the first and second galleys, and wherein the cap and second cap have a slot on one surface of a first end of the cap, and a corresponding lip on a lower surface of a second end of the cap such that the slot of a first cap can interlock with the lip of a second matching cap to retain the first end of the first cap to the second end of the second matching cap.

18. The method of claim 17, wherein the slot is open to and provided on an upper surface of the top portion at the first end of the cap, and the lip is provided on and extends downwardly from a lower surface of the top portion at the second end of the cap, said lip being adapted to fit into the slot.

19. The method of claim 16, further comprising placing an end plate at one end or at two ends of the chamber.

20. The method of claim 16, further comprising:

placing a third concrete galley having a third top deck and fifth and sixth downwardly-extending side walls in the excavated worksite substantially parallel to and a distance apart from the second galley to provide a

longitudinal channel between the second and third galleys; and

placing another cap having an arch-shaped top portion and two side base portions, each side base portion having a horizontal strut extending laterally away from the top portion and a vertical strut extending downwardly from the top portion, over the longitudinal channel by positioning the horizontal struts of the side base portions on the second and third galleys, thereby forming a second chamber.
