Research on the Application of UV-curable Repair Technology in the Repair of Drainage Pipe Network
There are about 150 drainage pipe defects in an old drainage pipe network renovation project in Longyan,Fujian Province,which need to be repaired.The traditional repair of drainage pipes is mainly through excavation and replacement or maintenance of damaged pipes,which has a long construction period and will cause interference to the surrounding environment due to the excavation of the current pipeline.In order to solve the problem,the project department adopted the UV-curable repair technology to repair the drainage pipe defects,and tested af-ter the completion of the construction.All the indicators met the requirements,and the construction period was saved about 23.7%,and the cost was saved about 19.3%.
