ても、先端では上記数値の２倍、即ち、1.05mの範囲が
改良未処理部として残ることとなるという問題点があ
る。Generally, the processing depth for stabilization processing is
Since it will be about 10 m, if the processing machine is not controlled in the left-right direction and the processing machine is tilted 3 degrees, the tip 10 m ahead will be displaced from the vertical position of 10 × sin 3 ° = 0.523 m. Moreover, when the turret 1 moves from the position of the turret 1 to the right end in FIG. 4, it is obvious that the inclination direction is opposite. When moving to the treated ground and performing stabilization treatment,
Since the tilt direction of the turret 1 is opposite, even if the turret 1 is continuously treated on the surface of the earth, there is a problem that at the tip, twice the above numerical value, that is, a range of 1.05 m remains as an untreated portion.
ところが、現在軟弱地盤処理機として使用されている機
