Abstract:This paper introduces the methods of repairing trenchless pipelines， including the solidification of linings， short pipes， piece linings， spiral linings， traction lining， coating lining and so on. The principles and processes of various methods are described. Through the analysis of the pipe network in the project of the comprehensive treatment of water environment along the Shili River in Jiujiang City， the applicability of the technologies to different trenchless pipelines are compared. Eventually， hot water curing and UV curing are chosen as the methods for repairing trenchless pipes. These two methods do not affect traffic. There are quick speeds of laying pipes， high efficiency， nothing damaged in the environment， no impact on people's normal work and life. The methods have great economic and social benefits.
