摘要
青草沙凌桥支线C3标工程第一次成功地完成了长距离大口径空间三维曲线钢顶管施工,该文以此工程为背景,对钢顶管曲线铰接结构形式进行了探讨,改进了原有的铰接结构形式,总结了铰接接缝处理技术和施工要点,为今后曲线钢顶管施工提供有益的借鉴。
Based on the long-distance curve pressure tunnel of Qingcaosha Lingqiao extension line which used steel pipe for the first time, the joint structure of pipes was analyzed and improved. The hinged-joint technology and construct points would be a useful reference for similar projects.
