Method for raising any object lying on the bottom of the sea, a river or basin, and apparatus used thereby

Method for raising a sunken ship, and generally any object lying on the bottom of the sea, a river or a basin, comprising arranging a lifting platform adjacent the object to be raised, from said lifting platform supporting tubes are arranged in relation to the sea bottom at an angle from 10.degree. to 90.degree. to lay a connection between the lifting platform and the bottom, and inserting boring rods through said supporting tubes, whereby use is made of a means for boring connected to said boring rods which does not require rotating the boring rods proper and said boring means is bent at such an angle that said boring rods connected thereto are moved along a curve underneath the object to be raised, continuing boring until said boring means, with the boring rods connected thereto projects far enough out of the bottom, and finally use is made of the obtained bore to lead a cable from one side to another side of said object, wherein said boring means comprises a boring motor having a boring crown which revolves inside said boring rods due to a boring liquid being pumped through said boring rods, and wherein said boring crown is uncoupled and replaced by a sleeve and hook for a hoisting cable, said boring rods and boring motor with said hoisting cable are pulled back so that said cable remains inside said bore.
