LINING OF PRESSURE-FREE HYDRAULIC ENGINEERING TUNNEL

摘要

The purpose of the invention is to reduce the material intensity and increase operational reliability. The lining includes closed bearing rings 1, separated from each other by flat movement joints, which are made as follows. Within the seam of the 2 faults, the seams of the 3 lining are located in planes parallel to the fault. Within zones 4 of the influence of the fault on either side of the seam 2, the seams 5 of the lining are made in planes with a successively decreasing inclination. At the boundaries of zones 4 of the influence of a fault with unchanged blocks 6 of the rock mass, the seams 7 in the lining are made vertical. Soft seals are placed in the seams 3, 5 and 7. Bearing rings 1 are interconnected by rods 8 of high strength material. On the rods x 8 there are clutches of elastic material. During tectonic movements of blocks 6 of the rock mass, along the seam 2 faults of the lining ring 1, separated from each other by inclined 3 and 5 and vertical 7 lines, filled with soft gaskets, follow the deformation of the massif, along the seam, 2 faults. 1 il.
