英文摘要：Long-term used water supply pipelines are subject to multiple risks，and the traditional excavationbased method for repairing water supply pipelines has a significant impact on urban traffic and the environment. Therefore，it is imperative to explore the application potential of trenchless rehabilitation technology for water supply pipelines in high-density urban underground pipe networks. This paper reviews the research progress of trenchless rehabilitation technology for water supply pipelines，and combined with the actual working conditions of the Donghuan 2nd road DN500 inverted siphon water supply pipeline in Shenzhen，the ambient temperature cured in place pipe method is selected after comparing multiple schemes. The critical control points with lining pipe properties，pre-construction preparation，pipe pretreatment and lining installation are also detailed to ensure the scientific and practical feasibility of the repair process. Engineering practice shows that the ambient temperature cured in place pipe method has significant advantages of low cost，short construction period，and minimal impact. It successfully repaired the inverted siphon water supply pipeline with multiple bends. After the repair， the surface of lining pipe is smooth without defects，and the mechanical properties and water quality indexes meet the relevant regulations，which verifies the feasibility and high efficiency of the technology under complex working conditions. Trenchless rehabilitation technology can effectively solve the problems of excavation repair，but it still faces multiple challenges in practical application. In the future，it is necessary to further establish a complete technical system，increase the research and development of domestic materials and equipment，improve the posteffect evaluation standard，and clarify the engineering quota to promote the market application and sustainable development of this technology.
