Study on In-situ Curing and Repair Technology of Defective Pipe Network in Municipal Water Supply and Drainage Construction f σf εf
The conventional trenchless in-situ curing and repair technology of defective pipe network mainly uses the point ultraviolet light repair method to close the drainage pipe hole,which is easily affected by the changes of the head diameter of the pipe section,leading to some abnormal repair defects.This paper studies a new in-situ curing and repair technology of defective pipe network in municipal water supply and drainage construction.The example analysis results show that the in-situ curing and repair technology of defective pipe network in municipal water supply and drainage construction has good repair effect,reliability and certain application value,which can make some contribution to reducing the operation risk of municipal water supply and drainage network.
