- Abstract:
- Nine types of technologies commonly used in the repair of drainage pipeline, such as integral repair and localized repair, are summarized. The applicable conditions of various technologies are analyzed, and the auxiliary measures such as temporary drainage and grouting in the process of trenchless repair are introduced. The special cases of pipe bending, diameter changing and underground well encountered in the process of trenchless repair are summarized, also solutions and suggestion are given. Finally, based on a practical case of trenchless repair of a drainage pipeline in South China, the application of trenchless repair technology in urban drainage pipeline is introduced.
