下穿式铁路立交引道排水设计

Drainage Design of Approach for Grade Separation Underpassing Railway

针对城市中的下穿式立交引道,采用渗水管、雨水沟和排水管相结合的排水方式,对地下水和路面雨水进行收集后,通过雨水泵站提升后排入河道。该文结合工程,介绍了设计方法,可供类似工程参考。

In the light of the approaches for the underpass grade separations in the city,the drainage method combining with the seepage pipe,rainwater channel and drainage pipe is used. The underwater and the ground rainwater are discharged into the rivers after collected and lifted by the rainwater water pump stations. Combined with the projects,the article introduces the design methods able to be referred for the similar projects.
