PROBLEM TO BE SOLVED: To provide a method for creating a solidified pile, which can uniform ground strength in both horizontal and vertical directions, and which enables a treatment pile to be created by increasing its vertical rigidity. SOLUTION: In this method, the leading end of a solidified pipe creating apparatus with three agitating shafts the centers of which are arranged in an approximately triangular shape in plan view is aligned with the original position of the ground of construction, and a solidification material is ejected or jetted from the vicinity of the leading end of the apparatus with rotating the three agitating shafts to cause them to penetrate and to be lifted to construct the solidified pile with an approximately cross section in natural ground soil.
