- Abstract:
- In order to address urban waterlogging caused by heavy rain and control the impact of runoff pollution on river ecology, the design of the project of Kangqiao Road stormwater pumping station and pollution control and storage tank in Pudong New Area, Shanghai was optimized in the face of adverse factors such as limited land area for the pumping station, lateral water intake, and crossing the land of No.18 Rail Transit Line. By optimizing the overall layout of the pumping station, the storage tank, stormwater pumping station, and equipment room were positioned vertically. Various lifting port, ventilation well, and personnel entrances and exits were thoughtfully arranged within the confined spatial constraints to ensure efficient functionality. The underground diaphragm wall, with a depth of 73.70 m, was implemented to intercept the confined aquifer. This solution effectively addressed the challenge of maintaining a minimum clearance distance of 8 meters between the shield and No.18 Rail Transit Line, thereby ensuring the safe operation of rail transit. In response to the issue of significant variations in static head during the emptying process, caused by an effective water depth of 7.5 m in the storage tank, energy? saving optimization measures for variable frequency operation of the emptying pump were proposed. Through the utilization of CFD numerical simulation to analyze the inlet flow state and implementation of rectification measures such as setting a cross beam, the issue of lateral inflow mainstream deviation was mitigated, achieving stable inflow flow state and uniform flow distribution.
