Method for placing a concrete-structure load-bearing pile or anchoring pile into the ground, in which method by means of hits generating device (3) a pile hole forming equipment, like with an end piece (5) equipped tube (1, 17) is forced into the ground to an intended depth (S) to a place meant for the intended pile, after forcing concrete mass is lead into said tube (1, 17) and simultaneously the tube (1, 17) is drawn out of the hole by means of the hammering device (3) wherein concrete mass fill the space meant for the final pile and the end piece (5) remaining as a pile top. It is generated to the pile load bearing ability or anchoring pulling strength increasing shapes (8) in the pile front end or after desired distances by means of stopping or making slower the drawing up of the tube (1, 17) immediately in the beginning of the draw-up portion and allowing the concrete mass to form a widening portion (8) in the pile front portion either for increasing the pressure of the concrete mass or for producing vibration by means of hammering device (3) to the tube 1, 17) and concrete mass or by using both above mentioned together. |
