Analysis on the Design and Research of Restoration Schemes for Drainage Pipe Network in Old Urban Areas
In response to the problem of ubiquitous defects of municipal drainage pipe network in old urban areas,this article first analyzes the design requirements of restoration schemes for drainage pipe network,and then discusses the types and evaluation methods of pipeline defects.On this basis,the restoration methods for pipeline are determined.Finally,taking the renovation project of drainage pipe network in the old ur-ban area of Zherong County as an example,we propose specific restoration schemes for different types and levels of pipeline defects based on the situation of pipeline diseases,which may improve the collection rate of sewage effectively.This paper will provide a reference for similar restoration projects of drainage pipe network.
