Abstract

A waste water tank having an inner tank with an inner tank wall; a concentric outer tank with an outer tank wall; a plurality of inner walls extending from the outer tank wall to the inner tank wall, such that the plurality of inner walls divides the outer tank into a plurality of chambers; and a plurality of cables attached to and extending between adjacent pairs of the inner walls, such that the cables provide support to the inner walls when the chamber defined by the inner walls, the inner tank wall, and the outer tank wall is full of fluid and adjacent chambers are empty.

Claims

A cylindrical inner tank with an inner tank wall;

a concentric cylindrical outer tank with an outer tank wall;

a plurality of radially arranged inner walls extending from said outer tank wall to said inner tank wall, such that said plurality of inner walls divides said outer tank into a plurality of chambers; and

a plurality of cables attached to and extending between adjacent pairs of said inner walls, such that said cables provide support to said inner walls when the chamber defined by said inner walls, said inner tank wall, and said outer tank wall is full of fluid and adjacent chambers are empty.

2. The waste water tank of claim 1 further comprising a plurality of cables attached to and extending between said inner tank wall and said outer tank wall.

3. The waste water tank of claim 1 further comprising a plurality of turnbuckles connecting said plurality of cables to said inner walls.

4. The waste water tank of claim 2 further comprising a plurality of turnbuckles connecting said plurality of cables to said inner walls and to said inner tank wall and said outer tank wall.

5. The waste water tank of claim 3 further comprising a plurality of support angles, each with a plurality of holes, attached to said inner walls, such that said plurality of turnbuckles may be attached to said inner walls via said plurality of holes.

6. The waste water tank of claim 5 where each of said inner walls has a first side and a second side, and where a plurality of said support angles is attached to each said first side of each said inner wall and a plurality of said support angles is attached to each said second side of each said inner wall, where the plurality of support angles attached to said first sides are oriented vertically and the plurality of support angles attached to said second sides are oriented horizontally.

7. The waste water tank of claim 6 where the vertically-oriented support angles and the horizontally-oriented support angles each comprise:

a first leg, where said first leg is parallel to and attached to said inner wall; and

a second leg oriented perpendicular to said first leg, where said plurality of holes to which said plurality of turnbuckles may attach are located on said second leg.

8. The waste water tank of claim 7 where the first legs of the vertically-oriented support angles and the horizontally-oriented support angles have a plurality of holes spaced such that each hole in each first leg of each vertically-oriented support angle located on each first side of each inner wall aligns with one of the holes in one of the first legs of one of the horizontally-oriented support angles located on the second side of the same inner wall, and each hole in each first leg of each horizontally-oriented support angle located on each second side of each inner wall aligns with one of the holes in one of the first legs of one of the vertically-oriented support angles located on the first side of the same inner wall.

9. The waste water tank of claim 8 further comprising a plurality of bolts attaching said vertically-oriented support angles and said horizontally-oriented support angles to said inner walls, where each of said bolts extends through one of said holes in one of said first legs of one of said vertically-oriented support angles located on the first side of one of said inner walls, through said inner wall, and through the corresponding hole in one of said first legs of one of said horizontally-oriented support angles located on the second side of said inner wall.

10. The waste water tank of claim 9 further comprising a plurality of plates connected to said horizontally-oriented support angles and containing a plurality of holes, to which said plurality of turnbuckles may attach.

11. The waste water tank of claim 10 further comprising a plurality of bolts connecting said plurality of plates to said horizontally-oriented support angles.

12. The waste water tank of claim 4 further comprising a plurality of vertically-oriented support angles, each with a plurality of holes, attached to said inner tank wall and to said outer tank wall, such that said plurality of turnbuckles may be attached to said inner tank wall and said outer tank wall via said plurality of holes.

13. A waste water tank comprising:

a cylindrical inner tank with an inner tank wall;

a concentric cylindrical outer tank with an outer tank wall and a tank floor;

a plurality of radially arranged inner walls extending from said outer tank wall to said inner tank wall, such that said plurality of inner walls divides said outer tank into a plurality of chambers;

a plurality of cable dead man anchors attached to said tank floor; and

a plurality of cables attached to said inner walls and each extending from one of said inner walls to either one of said cable dead man anchors located adjacent said inner wall or another of said inner walls located adjacent said inner wall, such that said cables provide support to said inner wall when a chamber defined by said inner wall, another of said inner wall located adjacent said inner wall, said inner tank wall, and said outer tank wall is full of fluid and adjacent chambers are empty.

14. The waste water tank of claim 13 further comprising a plurality of cables attached to and extending between said inner tank wall and said outer tank wall.

15. The waste water tank of claim 13 further comprising a plurality of turnbuckles connecting said plurality of cables to said inner walls and to said dead man anchors.

16. The waste water tank of claim 14 further comprising a plurality of turnbuckles connecting said plurality of cables to said inner walls, to said dead man anchors, to said inner tank wall, and to said outer tank wall.

17. The waste water tank of claim 15 further comprising a plurality of support angles, each with a plurality of holes, attached to said inner walls, such that said plurality of turnbuckles may be attached to said inner walls via said plurality of holes.

18. The waste water tank of claim 17 where each of said inner walls has a first side and a second side, and where a plurality of said support angles is attached to each said first side of each said inner wall and a plurality of said support angles is attached to each said second side of each said inner wall, where the plurality of support angles attached to said first sides are oriented vertically and the plurality of support angles attached to said second sides are oriented horizontally.

19. The waste water tank of claim 18 where the vertically-oriented support angles and the horizontally-oriented support angles each comprise:

a first leg, where said first leg is parallel to and attached to said inner wall; and

a second leg oriented perpendicular to said first leg, where said plurality of holes to which said plurality of turnbuckles may attach are located on said second leg.
