亭子口水利枢纽大坝底孔钢衬安装技术简述

Steel Lining Installation Techniques of Bottom Outlet in the Dam of Tingzikou Water Control Project

亭子口水利枢纽大坝底孔钢衬安装存在工期紧、出口段由原设计的侧衬和底衬优化为仅侧衬、斜面定位和吊装设备特殊、进出口段10个工作面需同时安装等特点和难点,通过合理施工规划、精心部署,采用先组装后安装的方式满足了施工进度,保证了工程质量,同时为大坝主体混凝土浇筑赢得了时间。

The installation of steel lining for the bottom outlets of dam in Tingzikou Water Control Project has some characteristics and difficulties, such as a tighter duration, only side lining in the outlet sections optimized from original design of side and bottom lining, position at inclined planes and special lifting equipments, total 10 inlet and outlet sections being constructed at the same time. Through reasonable and meticulous construction planning, the construction schedule and project quality are guaranteed by the means of assembling first and then installing. The installation of steel lining for bottom outlets also ensures the pouring schedule of dam concrete.
