上海市某初雨水调蓄池工程设计要点

Design Essentials of an Initial Rainwater Storage Tank Project in Shanghai

摘要:

初雨调蓄池位于现状A塘南岸，东至B路，西至C港，初雨调蓄池主体设置于雨水泵站北侧停车场下，占地下空间面积690.8 m2，体积3 400 m3，排空泵160 m3/h。雨水泵房、初期雨水调蓄池为分建式泵房，故雨水泵站在具备区域排涝功能的同时，还具有截流初期雨水、旱流污水的功能。提供了有关工程设计的相关经验，可供其他初雨调蓄池项目作为参考案例。

Abstract:

The initial rainwater storage tank is located on the south bank of the A pond, east of B Road and west of C Port. The main body of initial rainwater storage tank is located under the car parking area on the north side of rainwater pumping station, covering an underground space area of 690.8 m2. Its volume is 3 400 m3, and the drainage pump can discharge 160 m3/h. The rainwater pump house and the initial rainwater storage tank are separated buildings. So the rainwater pumping station not only has the regional drainage function, but also has a function of intercepting the initial rainwater and dry flow sewage. The relevant design experience can provide the reference for the other initial rainwater storage tank projects.
