摘要
惠州市惠新大道跨东江大桥以19号引桥墩双壁钢围堰拆除为例,详细阐明了双壁钢围堰自浮上升原理、分节分块拆除周转使用技术。实践证明采用的自浮式原理拆除围堰施工技术,操作简单、无需潜入深水作业,大幅提高拆除工效、周转使用率,解决了双壁钢围堰水下拆除不安全因素多的难题,对今后深水双壁钢围堰拆除工程施工具有一定的借鉴价值。
The cross-dong steel bridge of Huixin Avenue in Huizhou City takes the demolition of double-wall steel cofferdam of No.19 approach pier as an example,and elaborates the principle of self-floating rise of double-wall steel cofferdam and the use of segmental block demolition and tumover.The self-floating principle adopted by the practice proves that the cofferdam construction technology is removed,the operation is simple>there is no need to sneak into the deep water operation,the demolition work efficiency and the turnover rate are greatly improved,and the problem of unsafe factors in the underwater demolition of the double-wall steel cofferdam is solved.The construction of deep-water double-wall steel cofferdam demolition project has certain reference value.
