Abstract

Изобретение относитс к гидротехническому строительству. Цель изобретени - снижение трудозатрат за счет сокращени предпускового периода при строительстве гидростанции. На первом этапе производ т предварительное стеснение русла частью земл ной плотины 1, начина от первоначального берега 5. Затем производ т отсыпку низового банкета 3 из горной массы и с отставанием от него на 30-50 м верхового банкета 2. Одновременно провод т отсыпку тела земл ной плотины 1 между банкетами 2 и 3. Конечный этап перекрыти - замыкание - провод т низовым банкетом 3. 1 з.п. ф-лы, 2 ил.FIELD OF THE INVENTION The invention relates to hydraulic engineering. The purpose of the invention is to reduce labor costs by reducing the pre-launch period during the construction of a hydropower station. At the first stage, the channel is preliminarily constrained by a part of the earth dam 1, starting from the original shore 5. Then the bottom banquet 3 is dumped from the rock mass and 30-50 m of the top banquet 2 are behind it. At the same time, the ground body is dumped Noah dam 1 between the feasts 2 and 3. The final stage of the overlap - closure - is carried out by the downstairs banquet 3. 1 Cp f-ly, 2 ill.

Claims

Claim

1. The method of blocking the river bed mainly during the construction of the hydroelectric station, including the restriction of the channel from one of the banks by putting forward two banquets - the top and bottom, characterized

30 in that, in order to reduce labor costs by reducing the pre-launch period during the construction of the hydroelectric station, in the process of overlapping before extending the upper and lower banquets, the basement part of the earthen channel dam 35, placed between the banquets, is first constructed, with the help of which the channel is first constrained, then put forward two banquets, and the horse banquet is sprinkled with leaving, and in the 4Q space between the banquets they continue to erect a channel dam, the filling of which is stopped together with tsypkoy rideable banquet overlap at the final stage, and the closure of the closure channel is performed grassroots banquet, the total bulk comb structures 45 are placed at the level required to start the first hydraulic unit.

2. The method according to π. 1, characterized in that, in order to increase efficiency, the horse banquet is sprinkled from the material of the bulk channel dam.
