摘要
汕头第二过海水管工程中钢管顶管一次顶进长度2080 m,是目前世界上一次顶进长度最长的钢顶管工程。该顶管成功地穿越不稳定的块石结构海堤和海底中风化花岗岩层两大障碍物,标志着顶管设计、施工技术的重大突破,拓展了顶管施工方式的应用范围。
The distance of pipe Jacking is 2080m in the second water-pipeline engineering across Shantou gulf. The pipe successfully got across the sea wall and weathering granite in sea. The length is the longest in the world. The completion means the progress of the technology of design and construction in pipe jacking engineering.
