GROUND IMPROVEMENT APPARATUS
To provide a ground improvement apparatus that can reduce the possibility of a corotation phenomenon occurring in a mixing and agitating area when soil to be improved is mixed and agitated by a pair of agitating members.SOLUTION: A ground improvement apparatus is configured to rotate a pair of rotating shaft members 111, 112 in mutually opposite directions around an axis so as to mix and agitate soil to be improved and a solidifying material by a pair of agitating members 121, 122 fixed to the pair of rotating shaft members 111, 112, respectively, to protrude in the radial direction thereof. The ground improvement apparatus comprises a shearing assisting member 220 protruding in the radial direction of the pair of rotating shaft members 111, 112 so as to be interposed between the pair of agitating members 121, 122, and being rotatable about the axis relatively to each of the paired rotating shaft members 111, 112.SELECTED DRAWING: Figure 1
【課題】一対の撹拌部材により改良対象土が混合・撹拌される際に、混合撹拌領域における共回り現象発生可能性の低減を図りうる地盤改良装置を提供する。【解決手段】地盤改良装置は、一対の回転軸部材１１１、１１２のそれぞれを軸線まわりに相互に反対方向に回転させることにより、一対の回転軸部材１１１、１１２のそれぞれに対してその径方向に張り出すように固定された一対の撹拌部材１２１、１２２によって改良対象土および固化材を混合かつ撹拌するように構成されている。地盤改良装置は、一対の撹拌部材１２１、１２２の間に介在するように一対の回転軸部材１１１、１１２の径方向に張り出し、かつ、当該一対の回転軸部材１１１、１１２のそれぞれに対して軸線まわりに回転自在に設けられた剪断補助部材２２０を備えている。【選択図】図１
