Abstract:

Aiming at the problems that the drainage area of Weihe River 1# rainwater outlet in Qinhan New Town in Xixian New Disctrict of Xian is too large and there are the system waterlogging safety risks, the optimization scheme of 1# rainwater outlet system is studied. Based on the provincial urban waterlogging control implementation scheme in Shaanxi Province, a series of problems in the 1# rainwater outlet system are analyzed, and the optimization principles and goals are proposed. The focus is on analyzing the safety of the rainwater system in the large catchment area and the ideas for the reconstruction of rainwater and sewage separation, which proposes the corresponding measures and suggestions for solving the urban water safety, water environment and water resource utilization.
