[0002] Local repair of drainage pipes is a series of repair measures for local damage or defects in the pipes, aiming to restore the normal operation of the pipes, prevent leakage, blockage and other problems, and maintain the integrity of the pipe system.

[0003] Among them, the UV curing repair technology is to insert a glass fiber hose impregnated with photosensitive resin into the pipe to be repaired, inflate it, and then use ultraviolet light to cure the CIPP hose to form an inner liner with a certain strength. It is like coating the inside of the pipe with a hard protective layer. The pipe repair can be completed without excavation. Therefore, the UV curing method can be used for all pipes that need to be repaired and maintained, especially for pipeline trenchless repair projects in downtown areas, residential areas and places with heavy traffic.
