The problems of pipeline aging and damage, blockage, poor hydraulic condition and leakageduring the operation of urban drainage network are analyzed. The commonly used trenchless repairtechnologies are summarized, including local resin curing repair technology, stainless steel doubleexpansion ring repair technology and ultraviolet curing repair technology. The working principle,advantages and disadvantages and process flow of different repair technologies are expounded. Thepractical application of UV curing repair technology is introduced. The flow capacity of the pipeline isimproved and the hydraulic conditions are improved.
