深水流急区双壁钢围堰施工测量技术

Construction measurement technology of double-wall steel cofferdams in deep water and rapid flow area

基于对在建工程武隆乌江大桥主墩双壁钢围堰方案的分析,就深水流急区域桥梁深水基础双壁钢围堰施工测量技术进行了探讨,阐述了首节钢围堰拼装定位测量、初步定位及接高测量等技术,以供参考。

Based on the analysis of the main pier double-wall steel cofferdam scheme at Wujiang Bridge in Wulong in the constructing project, the paper explores the measurement technology of the double-wall steel cofferdams in deep water and rapid flow area, and illustrates the assembly location measurement, the initial location and ascending measurement of the first segment of steel cofferdam, so as to provide some reference.
