地铁车站过河段围堰的设计与施工

Design and Construction of Cofferdam for Metro Station River-crossing Section

通过对界鸿河内围堰的设计优化,既满足了施工的需要,确保了基坑开挖的安全,同时满足了水务部门提出的该河道不能断流的要求,顺利完成了整个车站中施工难度最大的施工段,取得了良好的效果,可供其它类似工程参考。

The design optimization of the cofferdam within Jiehong River not only satisfies the construction demand, ensures the safety of foundation pit excavation, but also satisfies the requirement of no stopping the running water of this river put forward by the water departments, which smoothly completes the most difficult construction section in the whole station with the excellent effect,and can be referred for the similar projects.
