针对大吨位水下沉船打捞过程中对沉船及货物微损伤的作业要求,全新设计并研制了一套无接触式大吨位整体打捞技术与装备——弧形梁系统.该系统使用液压驱动技术实现机械化自动安装沉船兜底钢梁,并且穿梁过程中与沉船及货物无任何接触,大大提高了施工效率、作业安全以及对沉船本身的保护.该技术适用于无接触式整体打捞水下不同规模和任意形状大吨位物体,包括打捞船舶、飞行器、货物等,对沉船及货物损伤几乎无损伤,并成功应用于我国水下考古重大项目——“长江口二号”古船整体打捞项目.该研究成果为国内外水下打捞提供了创新技术与设备,同时大大提升我国在打捞、水下考古等领域的国际影响力.

In response to the operational requirement of salvage of wreck and cargo without damage during the salvage process, a new non-contact large tonnage integral salvage technology and equipment, i.e., the curved beam system, has been designed and developed, which uses the hydraulic drive technology to achieve automatic installation of beam under the wreck without contact with the wreck during the installation procession, greatly improves the wreck removal efficiency, the operational safety, and the protection of the wreck itself. This technology is suitable for non-contact integral salvage of large tonnage objects of different scales and shapes underwater, including wrecks, aircraft, cargo, etc. It has been successfully applied to the integral salvage of “Yangtze River Estuary II” ancient ship, a major underwater archaeological project in China, providing a technical support for breakthroughs in the underwater salvage technology at home and abroad.
