To provide a ground improving stirring device with novel structure capable of confirming rotation of a corotation preventing blade.SOLUTION: A ground improving stirring device 20 comprises: a rotation shaft 13; an excavation member 21 provided at a tip of the rotation shaft 13; a stirring blade 24 protruding on an outer periphery of the rotation shaft 13; a corotation preventing blade 26 pivotally provided on the outer periphery of the rotation shaft 13 so that rotation of the rotation shaft 13 is not propagated; and accelerometers 40 each installed in the stirring blade 24 and the corotation preventing blade 26. The excavation member 21 rotates to excavate the ground. The stirring blade 24 rotates to mix and stir excavated soil and a ground solidification material and form a columnar body in the ground.SELECTED DRAWING: Figure 2
【課題】供回り防止翼の回転を確認できる新規な構造の地盤改良攪拌装置を提供する。【解決手段】地盤改良攪拌装置２０は、回転軸１３と、回転軸１３の先端に設けられる掘削部材２１と、回転軸１３の外周に突設される攪拌翼２４と、回転軸１３の外周に、回転軸１３の回転が伝播しないように枢設される供回り防止翼２６と、撹拌翼２４および供回り防止翼２６にそれぞれ設置される加速度計４０とを備え、掘削部材２１が回転して地盤を掘削し、攪拌翼２４が回転して掘削土と地盤固化材とを混合攪拌して地盤中に柱状体を形成する。【選択図】図２
