某建成产业园区雨水泵站与初雨调蓄池叠建设计

Superimposed Design of Rainwater Pumping Station and Initial Rainwater Storage Tank in a Built Industrial Area

摘要:

以天津市滨海新区某已建成产业园区雨水泵站与初期雨水调蓄池叠建设计为例，从系统的布局、进水方式以及控制方案等方面进行探索，旨在实现节约土地、减少设备、降低投资以及确保排水系统安全运行的目标。采用上下叠建模式，初期雨水调蓄池和雨水泵房共用一套进水闸井和进水格栅井，在格栅井后、集水池前设置初期雨水截流沟以便有效收集初期雨水，初期雨水被导入下层初雨调蓄池；通过浮筒阀对调蓄池的水位进行自动控制，确保调蓄池的水量管理合理；中后期雨水由泵站提升外排。即便突发暴雨，超标雨水可瞬间超越初雨截流沟进入集水池，通过水泵外排，确保区域排水顺畅。

Abstract:

Taking the superimposed co-construction design of rainwater pumping station and initial rainwater storage tank in a built industrial area of Tianjin Binhai New Area as an example, the layout, influent pattern and control scheme of the system are explored in order to achieve the purpose of saving land, decreasing equipment, reducing investment and ensuring safe operation of drainage system. In this project, the up-and-down superimposed method is adopted. The initial rainwater storage tank and the rainwater pump house share a set of intake sluice well and intake grid well. An initial rainwater intercepting ditch is set in front of the rainwater collection tank behind the grid well to effectively collect the initial rainwater. The initial rainwater is introduced into the lower initial rainwater storage tank. The rainwater level of the storage tank is automatically controlled through the float valve to ensure the reasonable flow management of the storage tank. In the middle and late stages, the rainwater is lifted by the pumping station and discharged out. Even if there is a sudden rainstorm, the rainwater exceeding the standard can instantly exceed the initial rainwater interception ditch, enter the rainwater collection tank, and be discharged out by the rainwater pump to ensure the smooth drainage in the area.
