- Abstract:
- The causes of waterlogging in urban waterlogging points located in Jiujiang were analyzed to solve the problem of rainwater accumulation in small and medium areas of urban roads and improve the urban drainage and flood control system. On this basis, the triad urban waterlogging prevention and control concept of “planning-construction-management” was summarized. A rainwater pipe drainage model was established by using InfoWorks ICM software for analysis of the current flow capacity of rainwater pipe in Yangtze River Avenue. The results showed that the current rainwater system did not satisfy the rainstorm return period and drainage standards. The project adopted the systematic technology of “source reduction, pipe network discharge, simultaneous storage and drainage and terminal control” and measures for reconstructing waterlogging points of the Yangtze River Avenue to raise the rainwater pipeline to the 2-year return period discharge standard and the 30-year return period drainage standard.
