ABSTRACT:
An underground tank having a leak detection mechanism, wherein a conduit is opened into a gap formed between an inner tank in which a fluid is to be contained and an outer tank covering the inner tank, a prescribed pressure of gas is applied to the gap through the conduit and the change in the pressure of gas in the conduit is detected by a detecting device, so that a leak of tank can be investigated. A thin sheet is wound on the outside surface of the inner tank so that the narrow gap is formed between the inner tank and the outer tank.
