The invention discloses an underwater salvage method for a floating dock. The method comprises the following salvage steps that S1, the floating dock is driven to a salvage site; s2, the salvage device is started, a winch of the salvage device pulls and releases a steel wire rope, a salvage assembly on the steel wire rope is connected with the to-be-salvaged object, and the to-be-salvaged object is lifted under the action of the winch; s3, during fishing operation, the tail of the floating dock is stressed, water adding operation needs to be carried out on a water ballast space on the bow of the floating dock, and part of ballast water is preset in the water ballast space before operation is started; and S4, the to-be-fished object is directly pulled out of the water surface. And the salvaged object is subjected to self-floating repair or disassembly by utilizing the strong repair capability of the dock, and is dragged away along with the ship. Therefore, the fishing work is completed. The salvage method is suitable for various floating docks and is still used for floating dock functions at ordinary times. Only when the fishing boat is used for fishing, the fishing boat can be used for fishing objects of various tonnages within the range of the maximum lifting force borne by the floating dock, can be directly pulled out of the water surface, and is not limited by water depth and not influenced by water flow.
本发明公开了一种浮船坞用于水下打捞方法,包括以下打捞步骤:S1:将浮船坞开至打捞地点;S2:启动打捞装置,打捞装置的绞车拉放钢丝绳,通过钢丝绳上的打捞组件与待打捞物连接,在绞车的作用下进行对待打捞物进行升降;S3:打捞作业时,浮船坞尾部受力,浮船坞艏部压载水舱要进行加水作业,压载水舱在作业开始前,预置部分压载水;S4:直到将待打捞物直接拉出水面。再利用船坞的强大修能力,对打捞物进行自浮性修复或拆解,随船拖走。从而完成打捞工作。本打捞方法适用于各种浮船坞,平时仍为浮船坞功能使用。只有在作打捞工作时,作打捞船使用,可在浮船坞承受的最大举力范围内打捞各种吨位的物品,直接拉出水面,并且不受水深的限制和水流的影响。
