同步提升技术是将古船体及其内部文物无损打捞出水,并平稳转移至预定船坞的关键技术.从计算机控制液压同步提升的技术原理入手,以韩国“世越号”的水下同步提升项目为例,论证该技术迁移到水下文物打捞工程的可行性;开展本次古船体整体打捞迁移工程的提升器布置、控制动作和系统规划;介绍同步提升装备的施工实施细节,液压提升器服从竖向布置,硬件装配涉及钢绞线、底锚及支架、液压油缸、控制系统和水下销轴的安装.“长江口二号”古船体整体打捞项目的成功证明了大型油缸计算机控制系统在提升海洋沉船中的高效性,能保障打捞对象的安全性和完整性,为日后相关古船整体打捞迁移开辟了新的实施途径.

The synchronous lifting process is a key technology for non-destructive salvage and smooth transfer of ancient ships and their internal cultural relics to the predetermined dock. This paper, starting with the principle of computer controlled hydraulic synchronous lifting technology, and taking the actual underwater synchronous lifting project of Sewol in South Korea as an example, demonstrates the feasibility of the technology transfer to the underwater cultural relic salvage project. In addition, it elaborates on the planning of the elevator arrangement, control actions, and system requirements for the integral salvage and relocation project of the ancient ship. Moreover, it introduces the construction implementation details of synchronous lifting equipment. The hydraulic lift follows vertical layout, and the hardware assembly involves the installation of steel strands, bottom anchors and brackets, hydraulic cylinders, control systems, and underwater pins. The success of the integral salvage of “Yangtze River Estuary II” ancient ship has demonstrated the efficiency of the large-scale oil cylinder computer control system in improving the safety and integrity of the salvaged object in marine sunken ships, opening up a new implementation path for the integral salvage and relocation of related ancient ships in the future.
