Abstract
PURPOSE: To improve the ground without leaving unimproved part thereof by using an auger screw part wherein the diameter of the screw increases sequentially and a hardener-injecting device equipped with stirring blades in the upper part thereof in the soft silt ground and the like.
CONSTITUTION: A stirring blade 7 is constituted by fitting auger screws 5 and 6 having somewhat smaller diameters than a stirring blade 3 sequentially to the part under the existing stirring blade 3. By using such a blade 7, auger screws 5 and 6 are made to enter in a support layer 2 when the ground is stirred. Thus, no unimproved part is left even when the support layer 2 is inclined.
