PROBLEM TO BE SOLVED: To provide a ground agitation device capable of accurately and easily improving the soil at a desired depth.SOLUTION: A ground agitation device 1 includes: a straight support member 2 which is disposed extending vertically; and stirring bodies 4, 4 which are rotatably provided to a lower part of the support member 2. The ground agitation device further includes a pair of injection nozzles 14, 14 which are attached to a lower part of the support member 2 at both sides thereof for injecting a solidification material downward of the support member 2. The pair of injection nozzles 14, 14 is configured so that an injection direction thereof is inclined with respect to a horizontal plane and to cross each other in a side view.SELECTED DRAWING: Figure 1
【課題】 所望深さの地盤改良を容易に精度良く行うことができる地盤撹拌装置を提供する。【解決手段】 上下に延びるように配置される直線状の支持部材２と、支持部材２の下部に回転自在に設けられた撹拌体４，４とを備える地盤撹拌装置１であって、支持部材２の下部両側にそれぞれ設けられて、支持部材２の下方に固化材を噴射する一対の噴射ノズル１４，１４を更に備え、一対の噴射ノズル１４，１４の噴射方向が、水平面に対して傾斜し、且つ、側面視において互いに交差するように設定されている。【選択図】 図１
