LINING OF PRESSURE HYDRO-ENGINEERING TUNNEL

摘要

The invention relates to hydraulic structures, specifically to pressure tunnels passing through the section of an active tectonic fault. The purpose of the invention is to improve the operational reliability of the tunnel lining and reduce the cost of its construction and operation. Sealing elements are made in the form of adjacent two rings embedded in concrete 2 two semi-tubes. The diaphragm 6 is tightly attached to the inner walls of the semi-tube, it is curved in the form of a sinusoid. The inner cavity of the semi-tubes 4 is filled with plastic material 7. 4 Il.
