The invention provides a cofferdam type underwater plugging and salvaging process, and relates to the field of ship salvaging and floating, and the cofferdam type underwater plugging and salvaging process specifically comprises the following steps: S1, a diver enters water to detect a damaged ship, determines a damaged part, and then measures the size and shape of the damaged part; according to the method, cofferdam blocking and drainage floating of the large damaged ship are achieved, underwater cofferdam sealing is conducted on the outer portion of a cabin of the damaged ship body, after sealing is achieved through attachment of cofferdam steel plates and the ship body, seawater leaking into the damaged cabin is discharged through a water pump, and the buoyancy of the accident ship is recovered. The damaged ship is blocked and floated on the premise that the support of a large salvage engineering ship is not needed, the efficiency is high, and the cost is low.
本发明提供一种围堰式水下封堵打捞工艺,涉及船舶打捞起浮领域,所述围堰式水下封堵打捞工艺具体步骤如下:S1:潜水员下水探摸受损船舶,确定受损部位,然后测量受损位置的尺寸、形状;本发明中,通过设置本发明实现大型受损船舶的围堰封堵和排水起浮,通过对受损船体舱室外部进行水下围堰封赌,并且利用围堰钢板与船体贴合达到密封后,利用水泵排出受损舱室内漏进的海水,使事故船舶恢复浮力的方法,在不需要大型救捞工程船支持的前提下完成受损船舶封堵起浮,效率高,成本低。
