ABSTRACT:
A ground- or soil anchor is prepared and placed in the ground by drilling a bore hole at the chosen site by means of a drilling assembly which comprises an elongated tubular member which serves as drive shaft for the drill, which latter has tapering rear end and is designed to be pulled into the said tubular member, the leading end of which is split so that the parts thereof-on the drill being pulled into it-are spread apart and are eventually embedded in grout inserted into the bore hole.
