1 工程概述崇西水闸位于崇明县绿华镇新建河口以西约2.5km,为崇明县南横引河西部引排水出口。该闸为满足崇明经济大开发的需要,集引水、排涝、挡潮等多种功能而修建。工程由上海水利工程设计院设计,为3孔12m节制闸,其闸首基础底板宽度为42.4m,轴线长度29.0m,混凝土厚度为2.0m,一次浇筑的混凝土方量为2485.3m~3,不设分缝,需连续浇筑而成。大体积钢筋混凝土具有结构厚、体积大、钢筋密、混凝土量较多、工程条件复杂和施工技术高等 1 Project Overview Chongxi Sluice is located 2.5 kilometers west of the new estuary of Luhua Town, Chongming County, which is the outlet of diversion water to the west of Chonghe County. The gate to meet the needs of Chongming economic development, set diversion, drainage, tidal and other functions and built. The project, designed by Shanghai Water Conservancy Engineering Design Institute, is a 3-hole 12m control gate with a width of 42.4m, an axial length of 29.0m, a concrete thickness of 2.0m and a concrete pouring volume of 2485.3m ~ 3 Set points, need continuous pouring made. Large volume of reinforced concrete with structural thick, bulky, dense steel, more concrete, complex engineering conditions and construction technology
