description	PROBLEM TO BE SOLVED: To provide a method capable of collecting a cover in a distal end of a stirring rod.SOLUTION: According to the method, a stirring rod in which a stirring blade is mounted around a hollow tube is used. While discharging a solidification material, the stirring rod is rotated and intruded into the ground, and a solid cement column stirring sediment and the solidification material is formed around the hollow tube. A steel pipe of which the end portion is opened is then inserted into the hollow tube as a support and guide pipe, and the stirring rod is pulled up while being rotated in the state where the support and guide pipe filled with the solidification material is left under the ground. In a distal end of the hollow tube, a cover and tip blade 7 which is axially stopped by a pin 21d is mounted to be freely rotatable around the pin 21d.
