Fremgangsmåde til forankring af et objekt til jorden

A method for removing an anchor or foundation pile out of the ground comprises the steps of positioning a drill apparatus at a position where the anchor or foundation pile is to be removed from out of the ground and where it is coupled to an object for anchoring and/or founding the object to the ground, which anchor or foundation pile comprises an assembly of a head section and one or more rod sections connected to each other, decoupling a proximal end of the connected sections from the object, and removing the connected sections out of the ground by means of an upwards pulling force, while repeatedly disconnecting one of the rod sections therefrom. According to the invention the drill apparatus is a sonic drill apparatus, wherein during at least part of the removing of the connected sections of the anchor or foundation pile out of the ground, a sonic vibration is introduced into the connected sections.
