ABSTRACT:
A storage vault includes an inner tank entombed within a concrete outer tank by first erecting a pair of sidewall forms on a base plate to create an open-top enclosure. The wall forms are securely clamped together. A layer of concrete is then poured onto the base plate and the inner tank is lowered onto the layer of concrete. Concrete is poured into the enclosure to entomb the inner tank while the bottom layer of concrete is still wet. The inner tank is restrained by a pair of reinforced hold-down bars extending over the top of the enclosure and having a pair of downwardly extending hold-down tubes which contact the top of the inner tank. A back hold-down bar is forced downwardly by a chain which passes over the hold-down bar and is fastened to the base plate. 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.
