城市老城区防洪设施的建设与维护

Construction and Maintenance of Floor Control Facilities in Old City Areas

城市防洪设施主要有河堤、泄洪闸、防洪渠、雨水泵站、雨水管道、雨水检查井等。主要任务是:一.防止江、河水流在汛期受上游来水影响,下泄缓慢,发生漫过或冲破河堤进入城市,对城市人民生活和财产造成损失。二.防止城市暴雨过后由于强降水或连续性降水超过城市排水能力,致使城市内产生积水灾害的现象,同样会对城市人民生活和财产造成损失。该文分析了老城区防洪设施建设与维护中存在的问题,并提出解决问题的若干方法。

The floor control facilities of a city are mainly the riverbank,flood discharge gate,flood control channel,rainwater pumping station,rainwater pipeline and rainwater manhole,which main tasks are that the river water flow is prevented from influence of the water at the upper reaches during flood season when the water is discharged too slowly to overflow or break the riverbank into the city area,and the urban rainstorm is prevented to cause the waterlogging phenomena within the city area because of severe rainfall or continuous rainfall exceeding the urban drainage capacity,which will cause the loss of the people’s life and property of the city.The article analyzes the problems existing on the construction and maintenance of the flood control facilities,and puts forward some methods to solve the problems.
