临港新片区雨水泵站及初雨调蓄池合建设计

Co-construction Design of Rainwater Pumping Station and Initial Rainwater Storage Tank in Lingang New Area

摘要:

为响应上海市初期雨水治理及水环境改善要求，以临港新片区某雨水泵站及初雨调蓄池合建设计方案为例，探索在海绵城市建设标准较完善的新建区域，如何合理设置设施规模和优化设计方案。通过方案比选确定区域强排系统方案，并结合临港海绵指标体系，采用地块径流污染控制率加权计算与调蓄设施容积核算两种方法优化调蓄池容积。初雨调蓄池采用于雨水泵房侧面合建形式及重力-压力进水结合方案，配套水质在线监测，可为海绵城市完善区域市政末端调蓄设施设计提供工程实践参考，支撑区域初期雨水污染治理能力提升。

Abstract:

In response to the requirements of Shanghai for the treatment of initial rainwater and the improvement of water environment, taking the co-construction design scheme of a rainwater pumping station and initial rainwater storage tank as an example, it is explored how to rationally set the scale of facilities and optimize the design scheme in the newly built areas where the standards for sponge city construction are relatively perfected. The regional forced drainage system scheme is determined through the comparison of the schemes. Combined with the sponge index system of Lingang, the volume of the storage tank is optimized by using two methods of weighted calculation of the runoff pollution control rate of the plot and volume calculation of the storage facilities. The co-construction form on the side of the rainwater pump house and the combined scheme of gravity-pressure inflow are used for the initial rainwater storage tank equipped with online water quality monitoring, which can provide the engineering practice references for improving the design of regional municipal terminal storage facilities in sponge cities, and support the enhancement of the regional initial rainwater pollution control capacity.
