地道雨水泵站改造工程设计综述

On Design of Tunnel Rainwater Pumping Station Alteration Project

为了保证上海市外环线及沪嘉高速公路的贯通性,与之交汇的道路均采用了下穿式,配套的排水工程必须采用强排模式。通过对沪嘉立交雨水泵站改造工程实际设计经验以及结合施工配合过程中遇到的问题进行了总结及探讨,对原有地道雨水泵站流量设计及集水池大小的复核、设备选型及结构荷载等作了一些论述。

In order to ensure the smooth of the Outer Ring and the Hujia Expressway in Shanghai,all roads linked with the two are adopting the underpass type and the drainage work associated with these roads must adopt strong emission mode.Based on the Hujia Interchange Rainwater Pumping Station Improvement Project with its practical design experience and construction problems during the construction coordination process,several key points are discussed including the original flow design,the review set of pool,equipment selection and structure load,etc.
