<p>The invention relates to a method for forming a foundation pile in the ground utilizing a prefabricated pile shaft (15), placed with clearance into a tube (1) screwed into the bearing ground layer, which tube is provided with a screw blade (14). Between the wall of the tube (1) and the pile shaft (15), a self-hardening mass is provided. The tube (1) can be removed from the ground (11) in the unscrewing direction while operating as a screw conveyor. The tube (1) may also be retracted from the ground, initially without rotation, with a thick skin (19) of self-hardening mass being formed around the pile shaft (15), which mass is subsequently pressurized by causing the tube (1) to function as a screw conveyor.</p> |
