谈圆形双壁钢围堰环封施工技术的应用

摘要

结合长株潭城际铁路湘潭湘江特大桥深水基础施工应用实例,对圆形双壁钢围堰的应用背景和加工制作、浮运、下沉、定位及混凝土环封的施工方法进行了研究,并对其受力进行了分析,解决了圆形双壁钢围堰的技术性问题。%Combining the application example of the deep water foundation construction at Xiangjiang super-large Bridge along Changsha-Zhuzhou-Xiangtan intercity railway,the paper researches the application background of the circular double-wall steel cofferdam and the construction methods for the process and manufacturing,the floating,the sinking,the location and the concrete ring seal,and analyzes its stress,so it solves the technical problems of the circular double-wall steel cofferdam.
