The inner surface (11) of the wall structure of the rock cistern is a tightly sealing lining. The supporting layer (12) consists of a steel-reinforced water-tight sprayed concrete layer. Between the blasted rock surface (14) and steel-reinforced water-tight sprayed concrete layer (12) there is a sprayed concrete layer (13) well permeable to water, serving as a groundwater-conducting layer. In the sprayed concrete layer (13) well permeable to water, subdrain pipes (15) have been placed. The tightly sealing lining (11) consists of plastic, steel, fibre concrete or equivalent. |
