BOTTOM WATER SPILLWAY GALLERY OF COMBINED HYDRAULIC POWER STATION

摘要

The invention relates to hydraulic engineering. The purpose of the invention is to simplify manufacture. The donna spillway of the combined hydroelectric power station includes a water line, enveloping the plan of the aggregate unit of the hydroelectric power station, which has an input section, a secondary section of the hydroelectric station and an output section. The inlet and subaggregate sections are made with a rectangular cross section. The wall 7 is made of flat elements 11, having the shape of a trapezoid, and flat elements 12,13, having a triangular shape. Elements 12 are arranged vertically. This allows the sloping wall 7 to fit well into the path enveloping the suction pipe of the aggregate unit, and to make it from simple flat elements. 8 sludge. (L AG, with SD O5 co wore
