INSTALLATION FOR STORING OF NATURAL GAS

摘要

An installation for storing of natural gas or some other fluid comprises a lined underground storage space (10). Inside the rock wall (11) of the storage space there is a concrete layer (27) for supporting an inner impermeable lining layer (14). According to the invention, the concrete layer has a crack distribution control reinforcement layer (28) closer to the impermeable lining layer (14) than to the rock wall (11) in order to divide large cracks into smaller cracks and distribute the cracks over a larger area of the impermeable lining layer. Further, also according to the invention, there is between the impermeable lining layer (14) and the concrete layer (27) a non-binding sliding layer (29) to facilitate relative movements between the impermeable lining layer and the concrete layer.
