GROUND AGITATION DEVICE
PROBLEM TO BE SOLVED: To provide a ground agitation device that enables hard ground to be inexpensively constructed in a short period of time only by changing a shape of an agitation blade.SOLUTION: In a ground agitation device 10 in which a plurality of steps of agitation blades 14, 15 and 16 are provided in such a manner as to each protrude radially outward on an outer peripheral surface 11a of a rotatably-suspended rotating shaft 11, the lowermost-step agitation blade 16 provided on the outer peripheral surface 11a of the rotating shaft 11 is formed by being twisted so that an angle of inclination can become smaller toward a tip 16b from a base end 16a.SELECTED DRAWING: Figure 1
【課題】攪拌翼の形状変更のみで硬質地盤を短時間かつ低コストで施工可能にする地盤攪拌装置を提供する。【解決手段】回転自在に垂下される回転軸１１の外周面１１ａに複数段の攪拌翼１４，１５，１６を径方向の外方にそれぞれ突出するように設けた地盤攪拌装置１０において、回転軸１１の外周面１１ａに設けた最下段の攪拌翼１６を基端部１６ａから先端部１６ｂに向かうに連れて傾斜角度が小さくなるように捻り形成した。【選択図】図１
