摘要
以打捞工程为例,介绍了使用非开挖水平定向钻机在沉船打捞中穿引打捞钢丝的关键技术。沉船打捞过程中将打捞钢丝穿引过沉船底部是一个非常重要的环节,从打捞工程的应用情况来看,非开挖定向钻机穿引打捞钢丝技术作业精度高、速度快,符合工程要求。该技术的引进缩短了打捞工程中穿引打捞钢丝的时间,穿引打捞钢丝定位精确,减少潜水员水下高强度作业,对打捞工程的快速作业、打捞技术的提升意义十分重大。
Taking salvage project as an example, this paper introduces the technology of using trenchless horizontal directional drilling by which passing lifting wires through the wreck. In the process of wreck salvage, it is a very important link that lifting wires pass the bottom of wreck. In the application, the technology of using directional drilling by which lifting wires passing the wreck is highly accurate and effective, and meets the requirements of salvage project. The introduction of this technology shortens the time of pulling lifting wire around the bottom of wreck and locates accurately, resulting in reducing the work of divers. The technology is of great significance for increasing efficiency of salvage project and impro- ving salvage technology.
