ABSTRACT:
The invention relates to a method for arranging a foundation pile in the ground using a ground displacement drill, wherein a hollow drill pipe with a ground displacement drill attached thereto are jointly introduced as a foundation pile, with the aid of a pile cap coupled to the hollow drill pipe, into the ground under axial pressure, whilst rotating, and wherein during the introduction into the ground, via a liquid supply extending through the pile cap and the foundation pile, a liquid medium is supplied through the ground displacement drill to the ground, and wherein, after the foundation pile has been arranged sufficiently deep in the ground, the pile cap is thereupon uncoupled from the foundation pile and retracted from the ground, leaving the foundation pile behind, wherein during retraction of the pile cap, liquid is supplied via the pile cap to the space formed between the pile cap and the foundation pile. Further, the invention relates to a pile cap and a foundation pile which are used in the method according to the invention.
