METHOD OF CONSTRUCTING WATER OUTLET TUNNEL FROM NATURAL WATER RESERVOIR

摘要

The invention relates to the field of hydraulic structures, in particular, to methods for constructing a drainage tunnel used in lowering the level of natural water bodies. The purpose of the invention is to reduce the time and cost of construction, as well as increase the safety of work. The method includes penetration and concreting of the tunnel, starting from the exit portal, construction of the shaft and chamber of the gates and the deep intake cap from the finished tunnel by means of an explosion of rocky rock separating the reservoir from the tunnel. Before the explosion, the bridges made an advanced fortifying cementation of the site intake (About the tip. 2 Il.
