摘要:
A lifting platform or pontoon (1) is arranged adjacent the object (4) to be raised, from said lifting platform or pontoon (1) supporting tubes (5) are arranged at an angle from 90° to 10° to lay the connection between the lifting platform or pontoon (1) and the bottom (3) and boring rods are inserted through said supporting tubes (5), whereby use is made for boring of a means which does not require rotating the boring rods proper and said means is bent at such an angle that said boring rods connected thereto are moved along a curve underneath the object (4) to be raised, the boring is then pursued until said means with the connecting boring rods projects far enough out of the bottom (3), and finally use is made of the obtained bore to lead a cable from the one to the other side of said object (4).
