雨水泵站与初期雨水调蓄池集约化设计

Intensive Design of Rainwater Pump Station and Initial Rainwater Storage Tank

雨水泵站与初期雨水调蓄池是区域防洪及削减初期雨水面源污染的重要工程性措施之一,在城市建设用地日益紧张的情况下,雨水泵站与初期雨水调蓄池采用合建式建设日渐普遍。以上海市松江区某雨水泵站设计为例,对雨水泵站与初期雨水调蓄池分别采用合建和分建两种形式进行经济技术对比,并讨论建设用地紧张条件下雨水泵站与初期雨水调蓄池合建的集约化设计方案。利用各设施结构特点、设备选型等方面对泵站内富余空间进一步有效利用。通过CFD流态分析软件对该泵站的整体流动状态及漩涡形成风险进行模拟分析,进一步优化设计方案,为类似项目的工程设计提供参考。

Rainwater pump house rainwater pump station and initial rainwater storage tank are important engineering measures for regional flood control and reducing initial rainwater non-point source pollution.With the increasing shortage of urban construction land,the joint construction of rainwater pump station and initial rainwater storage tank is becoming more and more common.Taking the design of a rainwater pump station in Songjiang District of Shanghai City as an example,this paper makes an economic and technical comparison between rainwater pump station and initial rainwater storage tank,and discusses the intensive design scheme of rainwater pump station and initial rainwater storage tank under the condition of tight construction land.Make further effective use of the surplus space in the pump station by using the structural characteristics of various facilities and equipment selection.CFD flow pattern analysis software is used to simulate and analyze the overall flow state and vortex formation risk of the pump station,so as to further optimize the design scheme and provide reference for the engineering design of similar projects.
