Multi-wall storage tank which can be made up of a plurality of structure elements, and structure wall element for constructing such storage tanks

摘要

A storage tank (19) for receiving fluids which are harmful to groundwater is made up of a plurality of wall parts (21, 22, 22a) which form a continuous leakage-monitoring space in the tank wall (20). In order to be able to erect such a storage tank in situ as a large tank using individually transportable structure elements, the tank wall (20) is arranged axis-parallel to the main axis (12) of the storage tank, and the wall parts each extend over the entire height, are covered by a top (26) and stand on a base (24) which likewise ensures leakage monitoring, said wall parts being provided, at axis-parallel borders and the base border in each case, with leakage-monitoring-space connection zones. In order to achieve a high stability, the wall parts may be in a sine-wave-like shell form. <IMAGE>
