长江葛洲坝水利枢纽大江截流工程,已于1981年1月4日19时12分胜利合龙。截流合龙是按立堵方式在上游戗堤进行的。在历时约36个小时的龙口合龙施工中,抛填各种块石料和15～25吨混凝土四面体共约10.6万立米。合龙时的流量为4400～4800秒立米;龙口最大水深约10.7米,实测最大流速7米/秒,最终落差为3.23米。施工中创造了24小时抛投7.0万立米以上的高强度记录。本文概述大江截流工程实施简况。
The closure of the main dam of the Gezhouba Dam on the Yangtze River has been successfully concluded at 1912 on January 4, 1981. Closure closure is based on the clogging up the embankment in the upstream. About 36 hours long Longkou closure construction, throwing a variety of blocks of stone and 15 to 25 tons of concrete tetrahedron, a total of about 106,000 cubic meters. Closure when the flow rate of 4400 ~ 4800 seconds; Longkou maximum depth of about 10.7 meters, the maximum measured flow rate of 7 m / s, the final drop of 3.23 meters. Construction has created a 24-hour throwing more than 7.0 million cubic meters of high-intensity records. This article outlines the implementation of the interception project.
