摘　　要：以江顺大桥主桥Z4号主墩承台施工为背景,通过对该主墩施工环境和结构特点的研究,得到了大型双壁钢吊箱围堰设计和施工的要点,如封底方案比选、计算机控制液压同步升降技术等,最终确保了洪水期间围堰结构的施工安全和质量,延续了前一阶段钻孔施工赢得的时间优势。With the No. 4 main pier pile caps construction of Jiang Shun bridge for background, through the study of the construction environment and the structure features of the main pier, the design and construction key points of large double-wall steel boxed cofferdam are summarized, such as the back cover plan seleetion, computer-controlled hydraulic synchronous lifting technology and so on, which can ensure the construction safety and quality of the cofferdam structure during the flood and can win the construction time like the previous stage of drilling.
