Abstract

Rock chamber or tunnel, where the construction lying opposite the rock surface 10 is formed by a sealed inner coating 40 and at least one sprayed concrete layer 30. In order to eliminate the hydrostatic pressure caused by water leakage in the rock chamber, there is between the sprayed concrete layer 30 and the rock wall 10 a network construction 20 made of porous material with open cells, the hydraulic conductivity of which exceeds the hydraulic conductivity of the rock wall 10. <IMAGE>
