<P>PROBLEM TO BE SOLVED: To provide a method for creating a solidified pile by using jets with a plurality of flow lines, which enables a homogeneously solidified pile to be constructed by shortening a construction time. Ž<P>SOLUTION: In this creation method, a penetration process of rotating shaft is that a solidification material is stopped ejecting from an ejection nozzle, and is penetrated in while ejecting water from the tip of rotating shaft, when the rotation shaft is pulled up while being rotated, the solidification material is ejected from two or more solidification material ejecting nozzles which are annexed at the tip of horizontal wing extended from the rotation shaft, while forming the plurality of jet flows, and agitated and mixed with in-situ soil, so that the solidified pile can be created. The number of the rotations of the rotating shaft and a pull-up speed thereof are determined so that a pitch of loci formed by the solidification material ejecting nozzles can be set to be a predetermined value P which is selected from the range of 2.0-5.0 cm.
