摘要
钢板桩围堰由于施工周期短、综合成本低等特点,越来越多的深水基础开始采用。徐明高速淮河特大桥20号承台为直径26.0m的圆形承台,采用圆形钢板桩围堰。结合该工程实例介绍了钢板桩的打拔、腰梁安装、钢板桩锁口漏水处理、硬黏土层湿挖、封底混凝土浇筑等大直径圆形钢板桩围堰施工成套技术。
Because of short construction period and low cost,steel sheet pile cofferdam are more and more applied in deep-water foundations.The round pile cap of Xuzhou—Mingguang Highway Huaihe River Bridge No.20 pile cap has diameter of 26.0m,using a circular steel sheet pile cofferdam.Combined with the engineering practice,this paper introduces the construction of the steel sheet pile,installation of cofferdam,leakage treatment of locking steel sheet pile,pouring of the back cover of concrete and other complete sets of technology for large-diameter circular steel sheet pile cofferdam.
