The foundation pile involves a compact machine with an open drill motor (5). Hollow cylindrical steel pipes or pipe segments (1) to which an end part (2) is welded are used, with or without a weighted foot with a point and screwlines (3). A pipe segment (4) with the aid of the hydraulic rotary motor (5) and the pull-down (6) is inserted into the ground. During the rotation of the pipe or pipe segments (1,4), a hydraulic clamp (10) is set in action and the machine via plunger arms (7,8) is anchored to the concrete floor in order to guarantee the rotating torque. During the rotation, concrete/grout is applied (9), ensuring that the shaft formed in the ground accommodates the diameter of the pipe or of the weighted foot with point and screw lines. |
