Abstract

PURPOSE:To make it possible to accurately judge the air-tightness inspection of a tank chamber by excluding an error due to temp. change, by comparering two tank chambers buried underground under the mutually same condition while reading the pressure difference between both tank chambers. CONSTITUTION:At first, on the confirmation of the shut-off with the atmosphere of the opening parts of tanks T1, T2, valves V1, V2 are closed and, subsequently, valves V3, V4 are opened. By this operation, the gas in a bomb B is injected into tank chambers R1, R2 through hoses H1, H2. After the completion of gas injection is confirmed by the flow of a galvanoscope F, the valve V4 is closed while the valves V1, V2 are opened and, subsequently, the valve V3 is closed. In this state, the liquid level of the colored liquid in a U-shaped tube is monitored for a difinite time. If tank chamber R2 is pierced with a hole, pressure is fallen by gas leakage and, therefore, the height of the liquid level in the U- shaped tube changes from a, b, to a', b' and it can be accurately judged that the air-tightness of the tank chamber R2 is not maintained.
