The invention provides a method for threading a steel cable at the bottom of an underwater sunken ship by using crescent tunneling equipment, and relates to the technical field of sunken ship salvage, and the method comprises the following steps: step 1, after investigating and exploring the sunken ship, determining the threading number and position of the steel cable; 2, crescent tunneling equipment is arranged on one side of a preset sunken ship bottom steel cable threading point; thirdly, the angle of the crescent tunneling equipment is adjusted, the crescent tunneling equipment is operated to tunneling the shield type tool bit mechanism towards the other side of the sunken ship, and the crescent supporting structure is connected according to needs; 4, driving the bottom steel cable to pass through the bottom of the sunken ship while driving equipment drives forward driving; the crescent tunneling equipment and the shield type tool bit are adopted, the aperture with the diameter of 1 m is directly threaded, the bottom steel cable can be directly driven to pass through the bottom of the sunken ship, the method can be applied to almost all seabed sediments, and threading operation of the sunken ship bottom steel cable can be safely and efficiently completed.
本发明提供了一种水下沉船利用月牙掘进装备穿引沉船底部钢缆的方法,涉及沉船打捞技术领域,包括以下步骤:步骤一:对沉船进行调研探查后,确定好钢缆穿引的数量和位置;步骤二:将月牙掘进设备布置在预设的沉船底部钢缆穿引点一侧;步骤三:调整月牙掘进设备的角度,操作月牙掘进设备将盾构式刀头机构向沉船另一侧掘进,根据需要接续月牙形支持结构;步骤四:掘进设备向前掘进的同时,将底部钢缆一并带过沉船船底;本发明采用月牙掘进设备以及盾构式刀头,直接穿引直径1米的孔径,可以直接将底部钢缆带过沉船船底,对于几乎全部的海底底质都能适用,有利于安全、高效地完成沉船底部钢缆的穿引作业。
