Ground improvement apparatus
A ground improvement apparatus includes: an inner shaft arranged inside an outer pipe and including a mechanism for rotating a crank at a rotation speed four times as fast as that of the outer pipe; agitation blades supported by the outer pipe so as to reciprocate in a radial direction of the outer pipe and including discharge outlets; and a slider crank mechanism for converting a rotation movement of the crank to a reciprocating movement of the agitation blades. A ground at a location where the outer pipe is penetrated and a solidifying material discharged from the discharge outlets are agitated and mixed with each other to form an improved body having a substantially rectangular cross section by rotating the agitation blades while advancing and retreating the agitation blades relative to each other via the slider crank mechanism by rotation of the crank.
