Claims
- 1. Liquid containment apparatus comprising:
- (a) a cast enclosure having a plurality of sidewalls which project to define an open cavity;
- (b) tank means for containing a liquid within a storage compartment and including attachment means for coupling to said tank;
- (c) a cast cover which mounts to said sidewalls to cover the open cavity, wherein said cover includes reinforcement means for maintaining the rigidity of said cover, and wherein said reinforcement means is retained to said attachment means and integrally cast into the cover such that the cover and tank means are aligned and bound to one another and removeable as a unit from said enclosure.
- 2. Liquid containment apparatus comprising:
- (a) a concrete base having a bottom wall and a plurality of sidewalls which project from the bottom wall to define an open cavity;
- (b) tank means for containing a liquid within a storage compartment and including attachment means for coupling to said tank means; and
- (c) a removeable concrete cover supported to said sidewalls to cover said cavity, wherein said attachment means is cast into said cover such that said cover and tank means are integrally aligned and bound to one another and removable as a unit from said base.
- 3. Liquid containment apparatus comprising:
- (a) a concrete base having a bottom wall and a plurality of sidewalls which project from the bottom wall to define an open cavity;
- (b) tank means for containing a liquid within a storage compartment and including a plurality of standpipes communicating with said storage compartment and further including attachment means for coupling to said tank means; and
- (c) a concrete cover supported to said sidewalls to cover said cavity, wherein said standpipes project through said cover, and wherein said attachment means is cast into said cover such that said cover and tank means are integrally aligned and bound to one another and removable as a unit from said base.
- 4. Apparatus as set forth in claim 3 wherein interior surfaces of said base and cover are lined with a thermal insulation.
- 5. Apparatus as set forth in claim 3 wherein said base includes a liquid impermeable membrane, which membrane terminates at a peripheral edge of said sidewalls to contain liquid above said membrane in the event of tank leakage or spillage.
- 6. Apparatus as set forth in claim 5 including sump means for removing liquids collecting in said base.
- 7. Apparatus as set forth in claim 5 wherein said tank means comprises an enclosed metal container and wherein said cover includes seal means for sealing the juncture between each standpipe with the cover.
- 8. Apparatus as set forth in claim 5 wherein interior surfaces of said sidewalls of the base vertically taper to define an open cavity of greater circumference at said peripheral edge than at the bottom wall, and wherein the interior surface of the bottom wall is sloped to one end of the base.
- 9. Apparatus as set forth in claim 5 including means for lifting said cover, which lifting means is secured to said tank means and extends through said cover.
- 10. Apparatus as set forth in claim 5 wherein said base includes a plurality of external support feet which support said base above a support surface and further including means for supporting said tank above the bottom wall.
- 11. Apparatus as set forth in claim 5 wherein said cover includes means for communicating with a space between said base and said tank means.
- 12. Apparatus as set forth in claim 5 wherein said cover includes means for aligning said cover to said peripheral edge.
- 13. Apparatus as set forth in claim 5 wherein said tank comprises a double jacketed container, and wherein a first jacket defines said storage compartment.
- 14. Apparatus as set forth in claim 2 wherein said base includes a liquid impermeable membrane, which membrane terminates at a peripheral edge of said sidewalls to contain liquid above said membrane in the event of tank leakage or spillage.
- 15. Apparatus as set forth in claim 2 including sump means for removing liquids collecting in said base.
- 16. Apparatus as set forth in claim 2 wherein interior surfaces of said sidewalls of the base vertically taper to define an open cavity of greater circumference at said peripheral edge than at the bottom wall, and wherein the interior surface of the bottom wall is sloped to one end of the base.
- 17. Apparatus as set forth in claim 2 including means for lifting said cover, which lifting means is secured to said tank means and extends through said cover.
- 18. Apparatus as set forth in claim 2 wherein said cover includes means for communicating with a space between said base and said tank means.
- 19. Apparatus as set forth in claim 2 wherein said cover includes reinforcement means for maintaining the rigidity of said cover, and wherein said reinforcement means is retained to said attachment means and integrally cast into said cover.
- 20. Apparatus as set forth in claim 1 wherein said base includes a liquid impermeable membrane, which membrane terminates at a peripheral edge of said sidewalls to contain liquid above said membrane in the event of tank leakage or spillage.
- 21. Apparatus as set forth in claim 1 including sump means for removing liquids collecting in said base.
