打捞沉船时高效、安全地工作是非常重要的.将打捞用的钢绳(也称千斤)穿过沉船是打捞作业中重要的一步.目前,这项工作主要由潜水员在水下通过人工方式完成.由于水下环境复杂,工作较为困难.本文在仔细研究了非开挖技术及分析了人工穿千斤的特点基础上,提出了一种打捞沉船穿千斤的新方法.它是将陆地定向钻技术与水下人工攻泥器技术相结合,构成一种新的可控穿千斤攻泥器.它包括攻泥头、驱动机构、检测部分以及控制电缆.陆地试验验证了其有效性.

Passing lifting wire through the sunken ship is key working procedure for sunken ship salvage.At present,it was finished by salvor through manual method.By means of carefully studying trenchless technology and analyzing the feature of manual passing rigging,a new method of passing rigging was presented for sunken ship salvage in this paper.It is a combine of directional drilling technique on land and manual mud-penetrator technique undersea.The innovated steerable mud-penetrator including the drilling head,drive mechanism,detection method and control cables are discussed in detail.The land experiment has test its validity.
