Abstract:To improve theeficiencyand environmental protection level of the drainage system,the keypoints and construction techniques ofrainwater and sewage diversion design forurban new district pipelines are analyzed.Through onsiteinvestigation,the mainreasonsforthe mixingofrainwaterandsewagehaveeenidentified,andasystematicraiwater and sewage diversion design scheme has been proposed,including the design pointsof drainage pipe network,municipal road underground pipe network,useraccess points,sewage outletsalong theriver,and branch pipe network.In termsof constructiontechnology,thekeytechnologiesoftrench excavation,pipelinelaying,pipelineclosedwatertesting,and trench backfiling are discussed indetail.Throughthedesignofrainwaterandsewage diversion,the effciencyof urban drainage systems can be effectivelyimproved,the impactof sewage ontheenvironmentcan bereduced,andthequalityof urban water environment can be enhanced.
