- Abstract:
- The rehabilitation of important municipal water supply pipes is often subject to traffic, environment and other factors, thus trenchless rehabilitation construction method is required. The DN1 000 steel pipe slip lining scheme was adopted in the reverse water supply rehabilitation project of the original DN1 200 prestressed concrete from Donghu water treatment plant (WTP) to Bijiashan WTP in Shenzhen. The technical and economic comparison, the core technological process, the working pit setup, the determination of key construction parameters such as traction force as well as the measures to deal with some technical problems in trenchless construction process were introduced, which could provide enlightenment and guidance for application of slip lining in trenchless rehabilitation between large diameter steel pipe and rigid pipe and for over 3 km distance.
