Abstract
Disclosed is a method for driving a screwable foundation, which comprises a thread-type external helix that has a pitch on the outer contour thereof, into the ground. In said method, a striking force is applied to the screwable foundation in the driving direction in alternation with or at least temporarily simultaneously with a torque when the screwable foundation is driven into the ground.
