PURPOSE:To raise the effect of consolidation by putting a large amount of a solidifying agent expansible by the absorption of moisture into a casing incorporated with a screw having partly provided blades. CONSTITUTION:By providing blades 8 partly to a screw 5, the occupying rate of the screw 5 in the casing is lessened and the amount of an expansible solidifying agent A in the casing 1 is increased. When the casing 1 is turned while closing a cover 3 at its tip and reaches a given depth, the expansible solidifying agent A is charged into the casing 1, the screw 5 is turned toward the charging direction of the agent A, the casing 1 is turned toward its drawing direction, and air is blown into the casing 1 from the nozzle 10. When the agent A is injected into the ground, the ground is consolidated in the diametral direction because the agent A absorbs moisture from the ground, expands, and solidifies. |
