PROBLEM TO BE SOLVED: To provide a device for forming a solidified pile capable of uniformly delivering in large quantities and providing an excellent working efficiency even when a large diameter solidified pile is formed. SOLUTION: In this device 10 for forming a solidified pile, solidifying material is delivered from either of uppermost and lowermost solidifying material delivery pipe ports among the solidifying material delivery pipe ports 31a and 31b and 41a and 41b located at two positions on the uppermost stage and at two positions on the lowermost stage totaling four places installed in the ground of a rotating area for the upper and lower two stage agitating blades 2a and 2b radially installed on the lower part of a rotating shaft 1 along agitating blades 2a and 2b, and mixedly agitated with soil at an original position. Two units of solidifying material feed pumps 5a and 5b are installed for each axis, selector valves 6a and 6b are installed on the sides of the solidifying material feed pumps, four routes 11a, 11b, 12a, and 12b connecting the selector valves to four solidifying material delivery pipe ports to feed the solidifying material are disposed in one axis, and the solidifying material is delivered from two solidifying material delivery pipe ports of the uppermost stage agitating blade or the lowermost stage agitating blade by the operation of the selector valves.
