泵站地下池体结构形式及施工方案对比分析

Comparison and Analysis on Structural Forms and Construction Schemes of Underground Tank in Pumping Station

借助某下穿铁路项目中雨水泵站的设计,比较了明挖式地下池体和沉井式地下池体的差异。首先从结构受力上入手,分析池体在不同形式下的受力情况。然后从明挖和沉井两种形式的工程造价、施工工期、施工技术要求和施工质量等方面进行对比。对比结果可为今后雨水泵站地下池体的结构形式和施工方案选择提供参考。

In virtue of the design of rainwater pumping station in an railway underpass project,the differences between the open-excavated underground tank and open-caisson underground tank are compared.Firstly,starting from the structural stress,the stress conditions of the tank body in different forms are analyzed.Then,the engineering costs,construction periods,construction technical requirements and construction qualities of two forms of open excavation and open caisson are compared.The comparison results can provide the reference for the comparison of the structural forms and construction schemes of underground tanks in pumping station in the future.
