して、形成範囲を任意に決めることができる。FIG. 3 shows the movement locus of the lower end of the stirring shaft 1 when the method of the present invention is applied by using the above-mentioned apparatus in comparison with the conventional method, and FIG. 4 schematically shows the stirring blade in the process of the operation. The present invention will be further described below with reference to these drawings. While being rotated by the drive motor, the stirring shaft 1 is penetrated to a predetermined depth in the ground as shown in FIG. The movement locus of the lower end of the stirring shaft 1 in the process of penetration and withdrawal is represented by the current depth with respect to time. In the conventional method involving the rotational movement or the rotational movement and the slight vibration, the stirring shaft 1 moves linearly as shown by the solid line a in FIG. 3, whereas the stirring shaft 1 performs the rotational movement and the regular vertical movement. In the accompanying method of the present invention, a wave having a predetermined amplitude is generated as shown by a broken line b in FIG. By operating the hydraulic cylinder 19 of the wave generator 8 described above, this wave motion causes the piston motion of the piston rod 23 to be applied to the wire 7, and the stirring shaft 1 in the middle of penetration or withdrawal rotates and the amplitude of the piston motion increases. It is formed by moving up and down. Stirring blade 6
When viewed as the movement locus of the above, it has a spiral shape with the thickness of the stirring blade 6 as the pitch. Further, the wave in FIG. 3 indicates that the hydraulic cylinder 19 was operating during the entire process of withdrawal from the penetration, but this wave moves the hydraulic cylinder 19 at an arbitrary depth, for example, when shifting to the withdrawal process. In operation, the forming range can be arbitrarily determined.

に行うことができる。As described above, as the stirring shaft 1 is rotated and moved up and down, the stirring blade 6 operates so as to form a spiral with the thickness thereof as a pitch, and a gap is formed around the stirring blade 6. It is formed efficiently. This is large in the case of the method of the present invention in which the amount of the improved material that can be discharged is vertically moved together with the rotational movement when the amount of the improved material that can be discharged is changed to the conventional rotational movement when shifting to the stirring and mixing in the penetration or drawing process. It was also confirmed by the stable injection. Further, the amplitude of the vertical movement was changed by replacing the hydraulic cylinder 19, and the discharge amount of the improving material in the stirring and mixing was examined. This effect, although it fluctuates to some extent depending on vertical movement and penetration, pulling speed, soil characteristics of the ground, etc., when the amplitude is 5 cm or more, more preferably 10 to 20 cm, the discharge amount of the improvement material is the largest and stable. I was able to inject. Here, the stirring and mixing means that a supply pipe arranged along the inside of the stirring shaft 1 is connected to a discharge port provided at the base of the stirring blade 6, and the improving material is discharged from the discharge port by the stirring blade 6. It is discharged into the gap of the formed in-situ soil, scattered along the rotation locus with the rotation of the stirring blade 6, and forcibly mixed with the in-situ soil. In this operation, it becomes difficult to discharge the improving material, and if the discharging is not performed smoothly, the quality of the formed pile or the like is immediately affected. However, since the method of the present invention enables the improved material to be stably discharged in a quantitative amount, the degree of mixing is naturally improved, and the quality of the forming pile can be improved. Moreover, when it is desired to use the improved material in a large amount, it can be performed as designed.

As an example, in the case of the conventional device which does not use the wave generator 8 of FIG. 1, the operator operates the winch drum 4
A predetermined amplitude can be formed by repeatedly performing the winding operation and the rewinding operation.
