- Abstract:
- The traditional rational method fails to systematically consider the impacts of spatiotemporal heterogeneity of watershed rainfall and ground infiltration capacity, as well as the pipe network conveyance process, resulting in an unscientific and unreasonable determination of the pump station construction scale. Taking the reconstruction and expansion project of Tiechuangling pump station in Nanjing as an example, this paper introduces the design methods for determining the design scale, pump configuration optimization and flow pattern analysis of the rainwater pump station. Based on the calculation results of the traditional rational method, the PC-SWMM software was adopted to construct a watershed hydraulic model, which was used to validate the rational method results and to reasonably determine the design scale of the pump station. For pump configuration optimization, a combination of large and small pumps was adopted, with two small pumps arranged on the north and south sides, and four large pumps in the middle. In addition, numerical simulation was conducted on the actual flow conditions during pump operation. The simulation results under different design scale conditions indicate that the pump station design scale (27.0 m3/s) calculated by the rational method is both reasonable and economical. Furthermore, with the optimized pump configuration and flow rectification measures, the drainage safety of the watershed can be ensured, the water environment quality can be improved, and the efficient and stable operation of the pump station can be guaranteed.
