下穿既有铁路线立交桥雨水泵站设计

城市道路拓展过程中常遇有下穿既有铁路线立交桥工程,雨水泵站的合理设计是下穿工程安全运行的关键要素之一。结合河北省磁县磁州路下穿既有铁路线立交桥雨水泵站的设计,在探讨泵站选址、规模确定、工艺设计等问题过程中,概述泵站自动控制、分区排水等技术应用的重要性,阐述排水接纳水体水环境、河势稳定、通航条件等对排水设计的约束。

Vdesign of Overpass Rainwater Pump Station in Crossing Existing Railway

In case of urban road development process often beneath existing railway overpass project,the rational design of rainwater pump station is the key element of safe operation in crossing engineering.With the design of overpass rainwater pump station in crossing existing railway in the Cizhou Road of Cixian,Hebei,investigated the location,size identification and other issues,discussed the import of pump station automatic control and drainage district,explained to accepted water drainage water environment,the stability of river,navigation conditions on the drainage design constraints.
