拉森钢板桩围堰在涉水深基坑中的应用

Application of Larsen Steel Sheet Pile Cofferdam in Deep Foundation Pit for Wading

本文主要介绍了在清远至云浮高速公路绥江大桥承台施工中,针对绥江江底的地质及地形条件,通过采用拉森钢板桩围堰,很好的完成了绥江水中承台及后续墩身的施工。不但保证了涉水承台深基坑的安全性和稳定性,而且大大降低了施工措施费用。减少了对绥江的地形影响,最大限度的保护了绥江周边的生态环境。该施工方法也为类似施工提供了一种解决思路。

This paper mainly introduces that in the construction of the Suijiang Bridge of Qingyuan-Yunfu Expressway,according to the geological and topographic conditions at the bottom of the Suijiang River,through the use of Larsen steel sheet pile cofferdam,the Suijiang water cap is well completed.and subsequent construction of the pier body.It not only ensures the safety and stability of the deep foundation pit of the wading platform,but also greatly reduces the cost of construction measures.It reduces the topographical impact on the Suijiang River and maximizes the protection of the ecological environment around the Suijiang River.This construction method also provides a solution for similar construction.
