To provide a ground improvement machine equipped with a device for preventing co-rotation of a swivel joint which is excellent in assemblability and can be used safely.SOLUTION: A rod 32 constituting an anti-rotation device 31 comprises a short large diameter pipe 34 fixed to one side of an auger 17, a long small diameter pipe 35 slidably provided coaxially therewith, a temporary holding portion 36 that creates a temporary holding state in which a center of gravity of the small diameter pipe is positioned below the large diameter pipe, and a fixed portion that creates a fixed state where the center of gravity of the small diameter pipe is located above the large diameter pipe. The temporary holding portion has a link rod 41 inserted into the large diameter pipe, and an abutment member 42 fixed to an upper end of the link rod and abutting an upper opening end 34b of the large diameter pipe to retain the link rod. The link rod has a protruding portion 43 that protrudes downward from a lower opening end 34a of the large diameter pipe in the abutting state of the abutting member. A locking pin 40 can be inserted into and removed from a pin hole provided in an overlapping portion of the protruding portion and a tip portion 39 of the small diameter pipe.SELECTED DRAWING: Figure 3
【課題】組立性に優れ、安全に使用することが可能なスイベルジョイントの連れ回り防止装置を備えた地盤改良機を提供する。【解決手段】回り止め装置３１を構成するロッド３２は、オーガ１７の一側部に固着された短尺の大径パイプ３４と、これと同軸に摺動可能に設けられた長尺の小径パイプ３５と、大径パイプの下方に小径パイプの重心が位置した仮保持状態を作る仮保持部３６と、大径パイプの上方に小径パイプの重心が位置した固定状態を作る固定部とを備え、仮保持部は、大径パイプに挿入されるリンク棒４１と、該リンク棒の上端に固着され、大径パイプの上部開口端３４ｂに当接してリンク棒の抜け止めをする当接部材４２とを有し、リンク棒は、当接部材の当接状態で、大径パイプの下部開口端３４ａよりも下方に突出する突出部４３を有し、該突出部と小径パイプの先端部３９との重合部に設けられたピン孔に係止ピン４０を挿脱可能にしている。【選択図】図３
