- Abstract:
- Taking the restoration of d1 800 mm main sewage pipe in Yunhe East Road (Jinkui Bridge to Tower Factory section) in Wuxi as an example, four kinds of trenchless pipe repair technologies are compared and the centrifugal-cast fiberglass reinforced plastic (FRP) pipe is selected. The pipe manufacturing process, characteristics and optimization measures, the liner pipe water flow calculation method, repair technical principle, construction procedure, applicable conditions, construction operation requirements, project implementation difficulties and solutions, as well as the engineering implementation effect are elaborated. Finally, the application prospect of the centrifugal-cast FRP liner pipe trenchless repair is prospected.
