摘要 |
The invention relates to a method for the construction of a system for storing liquid or gas in a storage space (1) in rock (2) or earth, lined with thin sheet (11), comprising a layer of a particle shaped drainage material (18), e.g. sand, gravel, or the like, in a space (16) between rock or earth and the thin sheet lining. An intermediate wall of corrugated sheet (15) is disposed at a distance from the rock or earth wall (17) and is anchored in the rock or earth wall. The space between the intermediate wall of corrugated sheet and the rock or earth wall is at least partly filled with said particle shaped drainage material, so that said material forms at least a layer between the intermediate wall of corrugated sheet and the rock or earth wall, the thin sheet (11), which shall form the lining, being fastened to the side of the corrugated thin sheet facing the interior of the storage space. The invention also relates to a storage system constructed according to the method. |
