Research on design of municipal water supply and drainage based on the concept of sponge city construction
As a key component of urban green ecological construction,the school's waterlogging problem has become a research hotspot in municipal water supply and drainage engineering.Taking a school in Xi'an as the research object,the optimal design of water supply and drainage scheme was carried out on the basis of the concept of sponge city construction.Seven optimization schemes of low-impact development facilities were proposed through the regional flooding cause model,and the optimal scheme was solved.The results show that according to the optimal scheme,the underlay asphalt pavement in the region is changed to permeable pavement,the green space is changed to rain garden,and the roof is changed to green roof,and the peak regional runoff under the 20-year return period is as high as 9.14 m3/s,and the time of waterlogging is cut by 92.45%,with the maximal overloading of 191.44 min.
