Method of salvaging applying ship loading and unloading and its device

Abstract

A method for raising a sunken object by loading and unloading the water in or from the ships alternatively features that a central big ship and two small ships at both sides of big one are parallelly arranged above the sunken object, the water is pumped from small ships into big one for floating the small ships up and in turn raising the sunken object, the water is then pumped from big ship into small ships for floating the big ship up and in turn further raising the sunken object, and said steps are alternatively repeated until the sunken object is raised on water surface. Its apparatus is also disclosed.

Description

technical field [0001] The invention relates to a salvage method and device, in particular to a salvage method and device using ship loading and unloading. Background technique [0002] Chinese patent application CN1274664A discloses a method of salvaging a sunken ship by using the steel wire cable buckle method. It first digs out a gap in the silt at the bow of the sunken ship by a dredger, and then two tugboats use a thin steel wire cable to cover people Pull back and forth at the gap at the bow of the sunken ship, pull the thin steel wire cable into the bottom of the sunken ship, then use a thick chain to widen the gap, and then tie a thick steel wire cable to the thin steel wire cable to pass through the bottom of the sunken ship, and then the thick steel wire cable will hang horizontally At the bottom of the sunken ship, after passing through several wires in sequence, a number of iron air drums are tied to the thick steel wire cables to float the sunken ship to the sur...
