归泾桥泵闸改建工程施工控制

Construction Control of Guijing Bridge Pump and Gate Reconstruction Project

归泾桥泵闸站是苏州城区防汛设施中重要的组成部分。因城市防洪标准提高及热导效应导致短期强降雨量增大,同时河道淤积及违章搭建使得河道过水断面逐年减小,泵闸运行调节水量的能力已无法完成它所担负的防汛任务,急需采取工程措施对该泵闸站进行更新改造并提升等级。该文详细分析了工程要点和施工特点,对基坑施工工艺、混凝土控制和闸门安装及泵型的选择进行了全面的阐述。

Guijing Bridge Pump and Gate Station is an important composed part in the flood control facilities of Suzhou City.The capacity of regulating the water flow by operating the pump and gate has been hard to fulfill its flood control task because of enhancing the urban flood control standard and increasing the short-term strong rainfall led by the heat island effect,and at the same time,the river filling up and illegal building to make the river discharge cross section reduced year by year. It is urgently to take the engineering measures for renewing,reconstructing and upgrading this pump and gate station.The article analyzes in detail the engineering gist and construction characteristics, and fully sets forth the pit construction technology,concrete control,gate installation and pump selection.
