- Abstract:
- The application of DN3 000 large diameter steel pipe jacking wholly located in deep silt layer in Shamen Emergency Access of Zhaoshandu Water Diversion Project is the largest steel pipe jacking water conveyance project in Wenzhou at present. The problems of surrounding environment impact of pipe jacking, durability of the pipeline and the soil instability caused low thickness are successfully solved by application of caisson structure, high-pressure jet grouting pile curtain, external corrosion prevention of epoxy glass flake and ballast on low thickness soil of river crossing pipeline. The project was successfully completed and began supplying water in October 2021.
