市域铁路隧道道床内置式区间废水泵房排水设计

Drainage Design of Built-In Section Wastewater Pump House in Track Bed of Municipal Railway Tunnel

以上海市域线机场联络线为例,探讨解决道床内置式区间废水泵房排水设计的关键技术。市域铁路具有区间长、埋深大的特点,通过分析道床内置式区间废水泵房的设计思路、总结既有案例,结合项目具体情况,针对设计重难点提出解决方案,可供类似工程借鉴。

Taking the Airport Connecting Line of Shanghai Regional Line as an example,it discusses the key technology to solve the drainage design of the ballast bed built-in interval wastewater pump house.The Municipal Railway has the characteristics of long section and large buried depth.By analyzing the design idea of the built-in ballast bed section wastewater pump house,summarizing the existing cases,and combining with the specific situation of the project,it puts forward solutions for the key and difficult points of the design,which can be used for reference for similar projects.
