Abstract
PURPOSE: To form a pillar-shaped body with uniform strength, which is hardened, by equally mixing pulverulent bodies in earth and sand by injecting the pulverulent bodies by pressing compressed gas into a pulverulent body injection pipe while upward pulling up the pipe.
CONSTITUTION: Agitating shafts 1 and a pulverulent body injection pipe 2 are mounted to a multiple spindle device 7 of an earth auger 3, the soft ground 4 is agitated by means of the agitating shafts 1 with agitating mixing blades 9 up to a fixed location of the soft ground 4 and the ground is vertically excavated by means of the pits 8 of the noses. Fixed pulverulent bodies 5 are charged to the pulverulent body injection pipe 2, a compressed gas sending-in pipe 12 is installed to the injection pipe 2, and compressed gas is injected while upward pulling up the multiple spindle device 7, thus injecting pulverulent bodies in the ground from a pulverulent body discharge port 14. The pulverulent bodies 5 injected are mixed with soil in the ground by means of the agitating mixing blades 9 to form pillar-shaped bodies 13 with biaxes. The pulverulent bodies 5 manifest strength required when they are hardened in pillar-shaped bodies because they have properties that are hardening expanded by a hydration reaction.
