Abstract
The invention relates to a pile-driving device and a method for driving driving material into a ground, wherein, for the purpose of driving-in, the driving material is clamped and held by means of a clamping means on a pile-driving power unit and prior to clamping the driving material is connected by means of a flexible securing element, in particular a securing chain, to the pile-driving power unit. In accordance with the invention a pressing element is provided which is displaced relative to the pile-driving power unit towards the driving material and, in doing so, a pressing force is applied onto an upward-directed front face of the driving material.
Claims16
Pile-driving device for driving a driving material into a ground, having
- a pile-driving power unit which is arranged in a vertically movable manner and has means for clamping and holding the driving material,
- a flexible securing element with which the driving material can be connected to the pile-driving power unit prior to clamping, and
- a pressing element supported in a displaceable manner relative to the pile-driving power unit for applying a pressing force vertically downward onto an upwardly-facing surface of a top edge of the driving material prior to clamping.
Method for driving or extracting driving material into or from a ground, the method comprising:
- providing a pile-driving device wherein the driving material is clamped and held on a pile-driving power unit and the driving material is connected by a flexible securing element to the pile-driving power unit, and
- displacing a pressing element relative to the pile-driving power unit towards the driving material such that a vertically downward pressing force is applied onto an upwardly-facing surface of a top edge of the driving material.
