摘要:
赵山渡引水工程沙门段检修应急通道采用了DN3 000大直径钢管顶管技术，顶管全程位于深厚淤泥层，是温州市目前正在运行的最大钢管顶管输水工程。通过沉井结构应用、沉井外围高压旋喷桩帷幕、管道环氧玻璃鳞片外防腐、穿河低厚度覆土段压载等措施，成功解决了顶管施工对周边环境的不利影响、管道耐久性和低厚度覆土顶管穿越可能产生的土体失稳等突出问题。2021年10月，该工程顺利完工并通水。
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.
