The present invention relates to a vibration compaction type deep mixing treating device for reinforcing the ground and constructing a barrier wall and a deep mixing treating method for the same. The vibration compaction type deep mixing treating device comprises: a boring grouting device; and a vibration compaction unit installed in the lower part of one or more rods selected among the rods and compacting the soil and grout with vibration when mixing the soil and the grout. The boring grouting device includes: the multiple rods connected to rotate in a normal direction and a reverse direction by receiving a driving force from an auger motor; multiple mixing wings fixed at vertically fixed intervals on the outer surface of the each rod; a mixing bit fixed to the lower end to mix the grout discharged through the mixing bit and mixing with the soil while excavating the grout according to the rotation of the rod. Multiple cutting units are formed in the vibration compaction unit in a radial direction on the outer surface of the lower part of the selected rod. Upper and lower finishing packings for preventing the grout and the soil from flowing into the upper part and the lower part in the rod through the cutting unit are individually fixed to the inner circumference of the upper and lower rods in a part where the cutting unit is formed. A bar-shaped vibrator is vertically installed to penetrate between the center part of the upper and lower finishing packings, so the vibration compaction type deep mixing treating device compacts the soil and the grout by vibrating the rod while vibrating in an air pressure method by the air supplied through a first airline or vibrating in an ultrasonic vibration type or an electric type through the connection of power. |
