摘要：

弧形梁管节顶穿施工作为“长江口二号”古沉船整体打捞施工中的重要环节,多根弧形梁管节需顶推穿越古沉船周边土体并形成底托包裹古沉船.弧形梁管节在结构形式、施工方式以及导向方式不同于传统整体打捞中的直线型底托梁,须研制并使用专用施工装备进行施工.曲线顶管发射架作为弧形梁管节顶穿专用施工装置,经过前期缩比模型论证、设计制造、等比试验及再优化设计制造后,顺利完成“长江口二号”古沉船海上打捞施工,在实际施工中客观地体现了其功能性、可靠性以及稳定性,将曲线顶管这类隧道领域中的施工方法运用到海上施工乃至古文物原址地基基础保护的设想成为现实.

Abstract:

As an important part of the integral salvage “Yangtze River Estuary II”, several curved beam sections had to be jacked through the soil around the wreck to form a bottom bracket to wrap the wreck. The curved beam sections are different in structure, construction method, and guidance from the traditional linear bottom brackets in integral salvage. Therefore, special construction equipment had to be developed and used. The curved pipe jacking launcher, as a special device for jacking through curved beam pipe joints, has successfully completed the salvage of “Yangtze River Estuary II” after preliminary scaled-down model demonstration, design and manufacture, isometric test and re-optimisation design and manufacture. The design and the application of the method can be applied to offshore salvage and in-situ protection of the foundation of the ancient relics.

Key words: salvage, pipe curtain method, pipe jacking, curved pipe jacking
