PURPOSE:To improve the effect of kneading excavated soil and a solidifying agent by forming the shape of the cross section of a rotary excavating mixer provided with a bit and a discharge port for the solidifying agent into a shape other than real circle. CONSTITUTION:When turning the rotator 7 of a multispindle device 2 to drive plural excavating kneading shafts 3 by turning a rotary driver 4, the rotation of the rotator 7 is transmitted to the excavating mixer shafts 3 because the hole of the rotator 7 is of a non-real circular form 6 similar to the cross sections of the excavating mixer shafts 3. As the multispindle device 2 is brought down along a leader 1, the ground A is excavated by a bit 11 while discharging a solidifying agent and the solidifying agent is completely kneaded with soil by a stirrer 10 and the non-circular excavating kneading shafts which is turning. |
