The salvage method comprises the steps that a diver finds and measures the damaged position of an accident ship, the size of a cabin sealing steel plate is prefabricated according to the finds and measured data, the cabin sealing steel plate outside the cabin is installed and fixed, the edge of the cabin sealing steel plate is sealed, the damaged cabin is inflated to lower the water level, and the buoyancy posture of the ship body is restored to be stable. The inflation hole and the drainage port are formed in the bottom of the damaged cabin, the inflation pipe inflates compressed air into the bottom of the repaired cabin, seawater leaking into the cabin is squeezed out till the ship body recovers buoyancy, and the ship body floats stably. According to the invention, plugging and inflatable floating of the large damaged ship are realized, floating salvage of the damaged ship is completed without support of a large floating crane engineering ship, the efficiency is high, and the cost is low.

    本发明公开了一种水下封舱充气起浮的打捞方法,潜水员探摸并测量事故船舶受损位置、根据探摸和测量数据预制封舱钢板尺寸、舱外封舱钢板安装固定、封舱钢板边缘密封措施、对受损舱进行充气降水位、船体恢复浮力姿态平稳。所述充气孔口及排水口设置在受损舱室底部,充气管向修复后的舱室底部充入压缩空气,挤压出舱内漏进的海水,直至船体恢复浮力,平稳起浮。本发明实现大型受损船舶的封堵和充气起浮,在不需要大型浮吊工程船支持的前提下完成受损船舶起浮打捞,效率高,成本低。
