- Abstract:
- As a new type of trenchless repair technology for pipeline, the trenchless rehabilitation technology for formed-in-place pipe(FIPP) using thermoplastic polymer liner can be used in the repair of pipelines with different cross sections and different purposes, as well as with large curvature radius, serious dislocation, diameter change and other complex situations, since it has the advantages of high strength, good toughness, strong corrosion resistance, convenient construction, close fit between liner and pipeline, and good repair quality. Taking 13 roads of Banqiao street in Nanjing as an example, the basic principle, characteristics, application scope and detailed performance parameters of the new in-situ thermoplastic pipe repair technology are systematically introduced, while the construction process, construction operation points and main quality inspection and acceptance standards are summarized, which can provide reference for similar projects.
