ABSTRACT:
A vault for dual containment of the fluids by an inner tank and an outer tank is produced by the apparatus described. The tendency of the inner tank to bob up in response to buoyancy from fluid concrete is countered by a hold-down assembly. The hold-down assembly produces downward pressure on the tank which is distributed over a region of the upper surface of the tank by a pressure distribution device which is left embedded in the concrete. An adjustment device is coupled to the form to permit pushing or pulling on the tank manway to move the manway down or up to provide the proper location.
