摘要
本文通过结合某特大桥施工实例,针对该工程桥梁基础施工需采用水下基坑开挖,系统对基坑开挖时所进行的围堰施工以及开挖工艺展开探讨,分析了承台基坑开挖围堰方案的选择要求,总结了钢板围堰施工及承台基坑施工技术要点,以期为同类工程提供参考借鉴。
This article,based on the construction example of a certain super large bridge,focuses on the underwater foundation pit excavation required for the bridge foundation construction of the project.The system explores the cofferdam construction and excavation technology during the excavation of the foundation pit,analyzes the selection requirements for the cofferdam scheme of the pier foundation pit excavation,and summarizes the technical points of steel plate cofferdam construction and pier foundation pit construction,in order to provide reference and guidance for similar projects.
