- Abstract:
- As an important trenchless pipeline repair technology, CIPP (Cured-In-Place Pipe) is widely used in the repair and renewal of sewage pipeline, and water supply pipeline and other water supply and drainage pipeline due to its advantages of fast construction speed, short construction period, tight fitting between the lining pipe and the original pipe, continuous lining pipe and smooth surface, etc. Based on a sufficient investigation of domestic and foreign research on CIPP repair technology, this paper reviewed the parameters of CIPP repair technology, including the elastic stability, structural stiffness, strength (bearing capacity) and peripheral earth pressure. This work points out the current defects in CIPP design and future research directions. In conclusion, we briefly introduce the engineering practice of CIPP repair technology in China, as well as the problems and challenges it faces, which could provide reference for further research on the mechanical characteristics of lining pipe.
