平原河网地区城市排涝泵站设计流量分析方法研究

Research on the Design Flow Analysis Method of Urban Drainage Pumping Station in Plain River Network Areas

  • 摘要: 平原河网地区汛期受外江水位顶托,区域涝水常难以自排,需新建排涝泵站解决内涝问题。以盐卡泵站为例,根据排区的降水、下垫面条件,分别采用平均排除法、水文水动力模型法确定平原河网地区外排泵站规模,以满足区域的排涝要求。经分析,传统的平均排除法和新型的水文水动力模型法各有优势,结合运用可以科学合理的确定排涝泵站设计流量,为区域经济社会发展提供水安全保障。研究成果可为平原湖区排涝泵站规模的确定提供参考。

     

    Abstract: The plain river network area is supported by the water level of the outer river during the flood season,and it is often difficult for the regional waterlogged water to drain by itself. It is necessary to build a new drainage pumping station to solve the waterlogging problem.Taking Yanka Pumping Station as an example,according to the precipitation and underlying surface conditions in the drainage area,the average elimination method and the hydrological and hydrodynamic model method are used to determine the scale of the drainage pumping station in the plain river network area to meet the regional drainage requirements. According to this analysis,the traditional average elimination method and the new hydrological and hydrodynamic model method have their own advantages,and the combined use can scientifically and reasonably determine the design flow of the drainage pumping station,and provide water safety guarantee for the regional economic and social development. The research results can provide a reference for determining the scale of drainage pumping station in plain lake area.
