改良材は、攪拌翼の回転に伴って回転軌跡に散布され、
原位置土と強制的に攪拌混合される。In this type of construction method, a stirring / mixing apparatus including a stirring shaft rotated by a drive device, a supply pipe arranged along the stirring shaft, a stirring blade provided on the lower end side of the stirring shaft, and the like. Is used. The improving material is conveyed at a low pressure through a supply pipe and is discharged from a root portion of the stirring blade or the like into a void portion formed by rotation of the stirring blade. The improved material discharged is scattered on the rotation trajectory as the stirring blade rotates,
It is forcibly mixed with in-situ soil.

共廻りを防ぐようにしている。In such a stirring and mixing treatment apparatus, the degree of mixing of the improvement material and the in-situ soil greatly affects the quality of ground improvement in addition to the selection of the improvement material. For this reason, especially in soft ground such as cohesive soil or beet layer, the soil tends to adhere to the stirring blades or between the stirring blades, and therefore corotation preventing means is provided in the vicinity of the stirring blades to prevent corotation. .

いからである。<Problems to be solved by the invention> However, in these conventional co-rotation preventing means, the clogging of the adhering soil adhering to the stirring blades or the stirring blades is forcibly rotated by the horizontal bar c or the co-rotation preventing blades h. Although it was stopped, it could not be expected to actively promote stirring and mixing. This means that even if the co-rotation preventing blades h are composed of a plurality of sheets, the prevention blades h have the same shape surface and maintain the same interval as the stirring blade, so that the rotation is stopped. This is because it is difficult to give a dynamic change to the movement direction of the soil.

拌軸４を引き抜く過程で行ってもよいものである。First, as shown in FIG. 9A, the stirring and mixing apparatus 1 is moved and positioned by a crane or the like, and then a stirring operation is performed while rotating the stirring shaft 2. The stirring shaft 2 is rotated by the driving device 10 connected to the upper end portion as in the conventional case, and is penetrated to a predetermined depth by the excavation means 3 provided at the lower end portion. Then, generally, the process of stirring and mixing is carried out in the process of penetration, but in this case, a supply pipe (not shown) arranged along the inside of the stirring shaft 2 is a discharge port (provided at the base of the stirring blade 4). (Not shown), and the improving material is discharged at a predetermined flow rate from the discharge port into the soil in situ stirred by the stirring blade 4. The discharged improving material is scattered on the rotation locus as the stirring blade 4 rotates, and is forcibly mixed with the in-situ soil by stirring. The stirring and mixing operation may be performed in a process of pulling out the stirring shaft 4 after the stirring shaft 2 is penetrated to a predetermined depth.

軸２の回転によって回転しない。FIG. 2B schematically shows the action when the large and small clods attached to the blades 4a, 4b, 4c of the stirring blades 4 or the stirring blades 4 are stopped by the co-rotation preventing means 5 in such a stirring and mixing process. It is shown in the figure. Note that the co-rotation preventing means 5 does not rotate due to the rotation of the stirring shaft 2 as a result of being subjected to the resistance of excavated soil or the like after being penetrated into the soil.
攪拌翼４の付着土は、１回転する間に防止板7a,7b,7c,7
dに当たって共廻りによる移動を４箇所で制止される。The adhering soil on the stirring blade 4 is prevented by the prevention plates 7a, 7b, 7c, 7 during one rotation.
The movement due to co-rotation is stopped at 4 places when hitting d.
