PURPOSE:To build a firm wall body, by a method wherein, by the use of a device which is constituted such that a screw part is located in juxtaposition with a rotary vertical shaft having an excavating head, and a chain, from which agitating blades are emerged, is stretched around two outer vertical shafts, a ground is excavated as a hardener is injected. CONSTITUTION:Plural vertical shafts 1 are rotated through rotation of an auger driving device 4. When a ground is excavated by a head 6, a mixture solution of water, cement, bentonite, etc., simultaneously, is injected through the outer vertical shafts 1 on both sides. Excavated earth is conveyed upward as the earth is mixed and agitated with the mixture solution with the aid of a screw part 2. Additionally, uniform mixture and agitation is effected through the working of a horizontal agitator 10 being constituted such that a chain 12, from which agitating blades 13 are emerged, is stretched around the two outer vertical shafts 1. |
