兴联路大通道项目跨湘江主桥哑铃型双壁钢围堰加工制作技术研究

Research on the Processing and Manufacturing Technology of Dumbbell-shaped Double-wall Steel Cofferdam for the Main Bridge Crossing Xiangjiang River in the Xinglian Road Grand Passage Project

双壁钢围堰在深水基础施工中是较为常用的施工方法,其中钢围堰的加工制作质量是重点。文章以兴联路大通道项目跨湘江主桥深水基础哑铃型双壁钢围堰施工工程为例展开分析,首先介绍了哑铃型双壁钢围堰的结构形式,然后对其加工制作技术要点进行研究,以供相关人员参考。

Double-wall steel cofferdam is a commonly used construction method in deep water foundation construction,whose processing and manufacturing quality is the key point.Taking the construction engineering of deep water foundation dumbbell-shaped double-wall steel cofferdam for the main bridge crossing Xiangjiang River in Xinglian Road grand passage project as an example,this paper first introduces the structural form of dumbbell-shaped doublewall steel cofferdam,and then studies the key points of its processing and manufacturing technology for reference by relevant personnel.
