市政排水与城市排涝标准衔接理念及其应用案例分析
|
摘要
极端天气带来的暴雨频发导致许多城市发生洪涝灾害,为系统整治城市排水排涝工程,彻底解决城市内涝问题,提出市政排水管网与城市排涝系统相衔接的理念。基于该理念,介绍了市政排水与城市排涝两套排水系统集水区域衔接、暴雨标准衔接、排水管道出口水位衔接的具体办法,并将其应用于广州市南沙新区起步区排涝规划设计中,其结论可为滨海城市的排水治涝作参考。
Frequent rainstorm due to extreme weather could lead to many cities' waterlogging disaster. In order to regulate urban drainage construction and to solve the waterlogging problem,the concept of connection between the two drainage systems of municipal drainage pipe network and urban waterlogging drainage system was put forward. Based on this concept,the measurements for matching catchment area,rainstorm standard and water level of outfall were introduced. These methods are applied to the waterlogging control planning of Nansha Start-area in Guangzhou. These methods could be used as reference in coastal cities for waterlogging control.
