Abstract:
PROBLEM TO BE SOLVED: To provide an excavation-agitation device particularly suitable when the bearing ground is comparatively shallow.SOLUTION: In an excavation-agitation device, an arrangement interval in the length direction of the axis of a rotary shaft 2 of an excavation-agitation blade 4 and an agitation blade 3 just above the same, or an arrangement interval in the length direction of the axis of the rotary shaft 2 of a blade of one agitation blade 3 and the other agitation blade 3 just above or just under the same, is set within the unit improvement depth which is: an interval substantially equal to the improvement depth down to a bottom surface of improvement soil from the ground surface of the ground being an excavation object; or an interval substantially equal to the depth of dividing the improvement depth into 1/n (n is an integer of 2 or more). Further, a corotation preventive blades 5 are provided between the excavation-agitation blade 4 and the agitation blade 3 just above the same and between the one agitation blade 3 and the other agitation blade 3 just above or just under the same, so that the excavation-agitation blade 4 or the agitation blades 3 and the corotation preventive blades 5 are successively alternately arranged along the length direction of the axis of the rotary shaft 2, and are also arranged at a substantially equal interval.
