浅谈老城区排水管道的改造

Discussion on the transformation of drainage pipes in old town

排水设施作为城市配套建设的重要组成部分,在城市建设中占重要地位。老城区雨污合流,导致环境污染;同时雨污水管道年久失修,常发生管道渗水、路面塌陷、路侧积水等现象;暴雨强度公式的更新也导致老城区雨水管道的管径不能满足现有规范要求。因此,亟须对老城区排水管道进行维护和改造,以满足城市发展的需求。

Drainage facility,an important part of urban supporting construction,have a pivotal position in urban construction.Rain and sewage converge in old town leads to environmental pollution.During the past years,due to lack of maintenance on rain and sewage pipes,water leak,road collapse and water accumulation on the side of the road occur from time to time.Furthermore,the delayed update of the storm intensity formula in old town also fails in meeting existing regulatory requirement of diameter of the rain water pipe.Therefore,to satisfy the needs for urban development,it is significantly necessary to maintain and transform the drainage pipes in the old town.
