ABSTRACT:
An underground double containment system consists of a concrete outer containment receptacle housing a primary fluid flow pipe which extends therethrough and is slidably supported on double I-beam structures within the concrete receptacle. The concrete receptacle can be provided with a removable cover providing access to the primary piping in modular sections defined by the boundary of the receptacle. The primary piping can expand or move along the longitudinal axis of the concrete receptacle relative to the concrete receptacle enabling thermal of the primary and containment piping outside of the receptacle, which can be formed from different materials, as the outer containment pipe can be connected to the interior of the receptacle at the juncture of the receptacle and the primary piping. A plurality of concrete receptacles can be joined at an angle of between 0.degree. and 180.degree. to provide a double containment system for nonlinear primary pipes.
