Abstract (en)
A method for driving a pile (1) into the ground to a position below the ground level by means of a lengthening piece (2) which is pulled out of the ground after the pile has been driven to the desired depth. The pile is provided with at least one pipe which is open at its ends, said pipe extending at least substantially along the length of the pile and being fixed to said pile. A lower end of a flexible pipe (11) accommodated within the extension piece is connected to the upper end of the pipe that is fixed to the pile, and an upper end of the flexible pipe that freely extends within the lengthening piece is connected to a grout pump via a lead-through extending through the wall of the lengthening piece. Grout is forced into the ground through the open lower end of the pipe (4), via the flexible pipe (11) and the pipe (14) fixed to the pile, by means of the grout pump during the pile-driving operation. Once the pile has been inserted, the lengthening piece is pulled out of the ground. <IMAGE>
