<P>PROBLEM TO BE SOLVED: To provide a soil improvement construction machine capable of performing soil improvement to a depth greater than ever. <P>SOLUTION: A ground agitation device 23 is connected to an arm 7 via an extension support 24. Thus, the extension support 24 is expanded/contracted to make the overall length of a soil improvement device variable. In addition, the ground agitation device is rotated by a cylinder via an intermediate member so that a connected location of a rod associated with rotation can be selected from among a plurality of through-holes corresponding to the overall length of the ground agitation device. <P>COPYRIGHT: (C)2013,JPO&INPIT |
