多軸混合処理機に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-axial mixing processor used for improving ground by injecting a ground stabilizer (ground hardening material) into in-situ soil excavated from soft ground and stirring and mixing the soil. The present invention relates to a multi-axis mixing processor used for a separation type (non-lap type) construction in which a plurality of ground improvement columns are formed separately with a certain distance.

る。2. Description of the Related Art Conventionally, the distance between a plurality of stirring and excavating shafts is larger than the diameter of each stirring blade attached to each stirring and excavating shaft.
When a so-called separated type ground improvement is to be carried out with a multi-axis mixing processor, the ordinary excavation method makes it impossible for the connecting metal fittings that hold each stirring excavation shaft to be held due to the resistance of the non-excavation soil between the stirring excavation shafts. Is. Therefore, generally, there was no choice but to construct the ground improvement columns one by one with the stirring excavation axis as a single axis. However, uniaxial construction requires a great deal of time and labor costs.

In the publication, a separate type multi-axis (2
A shaft) mixing processor is disclosed. The processor is equipped with a stirring blade 2 and a drilling cutter 3 as shown in FIG.
The main feature of the present invention is to provide a horizontal synchronizing shaft 5 which also serves as a connecting fitting for restraining and holding the vertical stirring and excavating shafts 1 and 1 of the book. The horizontal synchronizing shaft 5 is horizontally attached to a lower portion between the two stirring and excavating shafts 1 and 1 via bevel gears 4a and 4b. This multi-spindle mixing processor rotates each stirring and excavating shaft 1 so that the bevel gear 4a,
The rotation is transmitted to the horizontal synchronous shaft 5 via 4b, and the excavating blades 6 provided on the horizontal synchronous shaft 5 are rotated to excavate the non-excavated soil portion between the two stirring excavating shafts 1 and 1. Therefore,
The problem of the so-called connecting metal fittings being subject to resistance due to non-excavated soil is solved, and efficient multi-axis separation type improved construction becomes possible.

処して掘削することができない。As described above, in the conventional separation type soil improvement mixing processor shown in FIG. 2, the separation type soil improvement in which the stirring blades are not lapped is carried out by using a multi-axis construction. It is possible to shorten the construction time, which is inversely proportional to the number of axes, and save labor and manpower. However, the multi-axis mixing processor described above has a configuration in which the stirring excavation shaft 1 and the horizontal synchronous shaft 5 are rotated by common power for excavation, and therefore both shafts cannot be individually drive-controlled. Therefore, the excavation cutter 3 and the excavation blade 6 cannot be excavated by optimally coping with the conditions such as the hardness of the in-situ soil.
