Abstract:
The formed-in-place pipe (FIPP) rehabilitation technology utilizes thermoplastic polymer as liner. It can be softened repeatedly with hot vapor, and has good toughness, strong corrosion resistance, tight fitting, low cost and construction risk, thus it is a competitive trenchless repair technology nowadays. FIPP technology was implemented in a stormwater and sewer pipeline dredging, inspection and rehabilitation project in Yongchuan District of Chongqing. The technical principles, construction process, applicable scope, technical characteristics, liner thickness design, pipeline defect pretreatment, quality control and cost analysis were systematically introduced, so as to provide reference for application and cost analysis of similar trenchless rehabilitation work.
