湘江特大桥水中基础双壁钢围堰施工技术

Construction Technology for Double-well Steel-cofferdam of Submerged Foundation

以湘江特大桥水中基础施工为例,对深水低桩承台双壁钢围堰施工技术进行研究,通过采用水下爆破、浮龙门拼装平台等有效方法,成功完成双壁钢围堰的施工。

Taking the construction of Xiangjiang Bridge＇s submerged foundation as an example,this paper studies the construction technology for deep-water low pile cap＇s double-wall steel-cofferdam,and through adopting some effective ways such as the underwater explosion,and floating platforms,etc.,completes the construction of double-wall steel cofferdam.
