- a drilling blade 6 is provided at the lower end of the kneading shaft 5, and a screw-shaped moving wing 7 and a rod-shaped kneading wing 8 having the same diameter as the digging blade 6 are provided above the digging blade 6.
- the tips of the adjacent kneading blades 8 cooperate with each other to mix the in-situ soil and the mixed liquid to form a unit of continuous wall. If necessary, H-section steel sheet piles are installed on the continuous wall to improve soil retention and waterproofness.
- the inter-axis distance of the kneading shaft 5 is required to overlap the rotation range of the excavating blade 6 to continuously drill holes, which is limited.
- the vertical section of the H-section steel must be made along the axis of the kneading shaft, which is subject to restrictions.
- the outer diameter of the rotation locus of the excavating blade is on the both sides of the continuous wall obtained by the kneading shaft in the longitudinal direction of the unit.
- Triangle-shaped irregularities that are wrapped are formed, which is not desirable in terms of strength. The title exists.
- This multi-shaft kneading auger machine is a multi-shaft kneading auger machine having a plurality of kneading shafts used for forming a continuous wall in the ground. Since the excavation blade is provided, even if triangular irregularities in which the outer diameter of the rotation locus of the excavation blade overlaps are formed, the irregularities are excavated by the chain driven excavation blade.

- a guide shaft is provided on one side of the excavating machine having a plurality of excavating shafts whose axes are arranged on the same line.
- a jet nozzle is provided on the guide shaft.
- the multi-axis excavator of the present invention is a multi-axis excavator provided with three kneading axes used for forming a continuous wall in the ground, wherein a housing for maintaining a distance between the kneading axes is provided with a central kneading axis.
- the guide hole is pre-drilled, and the guide hole is guided by the Guy Byeon axis, and the hole is drilled by the excavation axis. Therefore, a plurality of continuous holes can be drilled with good linearity because the guide shaft receives the reaction force. Also, The guide hole uses the drill hole at the end of the primary hole where drilling has been completed, and can maintain continuity with the secondary hole.

- Fig. 17 is a cross-sectional view taken along line A-B-C-E of Fig. 16, and
- Fig. FIG. 19 is a side view showing the auger machine of FIG. It is a diagram.
- FIGS. 1 to 3 a plurality (three in the illustrated example) of rotatable excavating shafts 10 A, 10 B, and 10 C (hereinafter collectively referred to as 10) and one Non-time Inverted guide shafts 11 are arranged at equal pitches so that their axes are located on the straight line L.
- the excavating shafts 10 A to 10 C are connected to each other by interference prevention brackets 12 which also serve as a plurality of bearings, and of these brackets 12, several brackets 12 A Is connected to a clamp bracket 13A for selectively locking the guide shaft 11.
- a guide bit 14 is provided at the lower end of the guide shaft 11.
- the main body 15 overlaps with the outer diameter D of the rotation locus of the excavating blade 6 and the moving wing 7 adjacent to the excavating shaft 10 A in a cylindrical shape (both and the outer diameter R of the kneading wing 8 are formed equally).
- the portion is formed in the arc-shaped concave portion 16.
- the outer periphery of the main body 15 is provided with a pair of jet nozzles 17 for jetting the jet stream J in a direction parallel to the straight line L, that is, in a tangential direction.
- the guide bit 14 is excavated in a state where the guide bit 14 is lowered from the excavation blade 6 of the excavation axis 10 by a length L (for example, 500 to 70 O mm).
- This mode has good guideability by the guide bit 14, but the guide shaft 11 is unclamped by the clamp block 13 B before the length of the planned excavation depth L and the guide bit 1 is released. Work to make 4 free is required.
- the guide bit 14 and the excavation blade 6 are cut at the same level, or as shown in FIG. 10, the guide bit 14 is longer than the excavation blade 6.
