Practice and Discussion on the Reconstruction of Drainage Pipe Network in Urban Renewal
Drainage pipe networks in residential buildings,urban villages,and municipal roads have phenomena such as misconnection,confluence of rain and sewage,and pipeline diseases,which will cause problems such as natural water pollution,heavy sewage treatment bur-den,and urban waterlogging.Taking a rain and sewage diversion reconstruction project in Fujian province as an example,this paper deeply an-alyzes the current situation and existing problems of urban drainage,clarifies the transformation solution,puts forward typical node transforma-tion measures,and analyzes the transformation effect of the project through the monthly water intake index of sewage treatment plant and pum-ping station.Finally,the project implementation experience is summarized and the future development trend of similar projects is discussed,in order to provide theoretical guidance and technical support for the practice of rain and sewage diversion engineering.
