    • A method and a device for driving by means of simultaneously striking and vibration of an element that is in contact with or surrounded by a material mass, particularly a stratum of earth, the element either comprising a stamping plate that is in surface contact with the material mass in order to compact said material, or comprising an elongate object such as a pile or a tongue or a packing implement, which shall be driven into or taken out of the material mass. An energy source, e.g. a striking hammer or a vibrator, is caused to directly or indirectly apply impulses to the stamping plate in order to drive this towards or away from the material mass. The vibrating device is adjustable to the desired oscillation frequency which may be in the vicinity of the natural frequency for a system, defined by the element, the area of the material mass engaged by the element, and the vibrating device. In the case of driving an elongate element into the material mass the resonance frequency may be lowered in relation to the natural frequency for compacting the material mass around the elongate element in the final stage of driving in the elongate element, or an overtone thereof.
