Abstract

PURPOSE:To sense oil leakage from the welded part of a lining steel plate in the early stage, by providing a gas circulating path which covers all the welded part at the outside of a side plate and a flow path network in the crushed stone layer under a bottom plate, sending inactive gas, and analyzing the output gas. CONSTITUTION:The inside of a reinforced concrete body 1 of the underground tank is lined by the steel plate 2. The gas circulating path 11, which covers all the welded part of the side plate so as to accommodate the leaked oil from the welded part 2c, is provided on the outside of the side plate 2a of the tank. The inactive gas is flowed in said circulating path, and the output gas is analyzed. Thus the oil leakage from the side plate 2a of the tank is sensed. The flow path network 16 comprising a perforated pipe 17, wherein small holes 17a are provided on the circumference, is provided in the crushed stone layer 4 under the bottom plate 2b of the tank. The leaked oil flows into said small holes 17a. The inactive gas is flowed into said flow path network 16, and the output gas is analyzed, or the leaked oil which has flowed into the perforated pipe 17 is drawn up together with underground water and analyzed. Thus the oil leakage from the bottom plate 2b of the tank is sensed.
