摘要

The structure has a tank bounded by a wall and a double-walled base (3) including upper and lower bases that are arranged at a distance to each other. A catchment area is provided outside of the tank and the base (3) is connected to the area, such that the liquid acquired between the upper and lower bases is directed into the catchment area. A leakage monitoring device (10) monitors the liquid directed to the area.
