Analysis on Key Design Points for Quality and Efficiency Improvement of Drainage Pipe Network
By the end of 2021,the sewage treatment rate of urban sewage treatment plants in China is 97.89%,and the sewage centralized collection rate is 68.6%.The situation of rain and sewage confluence,mixed connection,direct discharge and leakage is common.The problems of sewage being discharged into rivers and external water entering the sewage pipe network can be solved by taking measures such as diversion transformation of confluence pipeline,transformation of sewage direct discharge outlet,mixed connection transformation,so as to improve the quality and efficiency of drainage pipe network.In order to ensure the construction quality,this paper summarizes the engineering practice,and introduces key design points such as pipe materials,interfaces,inspection wells,construction methods,pipeline soil covering,road repair,aiming to provide reference for the quality and efficiency improvement construction of drainage pipe network.
