地道桥雨水泵站原位升级改建设计

In-situ Upgrading and Reconstruction Design of Rainwater Pumping Station for Tunnel Bridge

以保定市建国路地道桥雨水泵站为例,通过分析地道桥暴雨积水主要成因,合理确定排水系统升级改造方案,在原用地不变基础上,将泵站规模由0.83 m^(3)/s提升至3.0 m^(3)/s,同时新增一座1200 m^(3)初雨调蓄池,共同实现缓解桥区内涝、改善水环境的目的,并为远期周边区域排水系统的彻底改造创造有利条件。

Taking the Jianguo Road Tunnel Bridge Rainwater Pumping Station in Baoding City as an example,by analyzing the main cause of waterlogging in the tunnel bridge area,the upgrading and reconstruction schemes of the drainage system are reasonably determined.On the basis of the original land unchanged,the scale of the pumping station is increased from 0.83 m^(3)/s to 3.0 m 3/s,and an initial rainwater storage tank with a volume of 1200 m^(3) is added in order to realize the purpose of alleviate the waterlogging in the bridge area and improving the water environment together,at the same time to create the favorable conditions for the thorough reconstruction of the drainage system in the surrounding area for the future.
