摘要： A method for use when installing piles, in which a pipe (2) or the like is inserted into the ground (1) and a flowing and solidifiable substance (3) is introduced into the ground through the pipe, in order, when solidified, to support a pile, and in which method the solidified substance is subjected to pressure in order to cause the substance to penetrate into the surrounding earth and/or to displace the earth, so as to provide an anchorage for the pile.The method is mainly characterized in that there is created in the proximity of and at least partially beneath the lower orifice (7) of the pipe (2), this pipe (2) constituting an outer pipe (2), a cavity (6) in which the aforementioned solidifiable substance, preferably concrete, is subjected to pressure with the aid of a raisable and lowerable body (5) which can be caused to protrude into the cavity (6) and which extends beneath the bottom orifice (7) of the outer pipe (2) at least during a given part of the period over which the solidifiable substance is placed under pressure, and is moved forcibly downwards during the pressure period with the aid of a downwardly directed force, in order to displace the solidifiable substance present in the cavity (6).The invention also relates to an arrangement for carrying out the method.
