ABSTRACT:
A storage vault (2, 182) includes an inner tank (4,4',152,180) entombed within a concrete outer tank (8) by first erecting a pair of sidewall forms (51) on a base plate (44) to create an open-top enclosure (54). The inner tank (180) can include a plastic tank (152) enclosed within an external framework (154), the combination (150) housed within a steel tank (174). A layer of concrete (56) is poured onto the base plate, the inner tank is lowered onto the layer of concrete, and concrete is poured into the enclosure to entomb the inner tank while the bottom layer of concrete is still wet. Reinforced hold-down bars (86) extend over the top of the enclosure and have downwardly extending hold-down tubes (92) which engage the top of the inner tank and keep the inner tank positioned horizontally and vertically. The hold-down bars are fastened to the base plate to keep the inner tank properly positioned. After the concrete has set sufficiently, the hold-down bars and tubes are removed and the holes created by the hold-down tubes are filled with concrete. After curing, the wall forms and base plate are removed from the vault created within the form assembly.
