AGITATION BLADE AND MECHANICAL AGITATION METHOD USING THE SAME
To provide an agitation blade which materializes improvement of ground agitation efficiency, and a mechanical agitation method using the same.SOLUTION: An agitation blade 14 includes a rotation member 76 having a substantially cylindrical shape, and a plurality of agitation impeller vanes 15 fixed to an outer peripheral portion of the rotation member 76, at least a part of the agitation impeller vane 15 among the plurality of agitation impeller vanes 15 has a platy slanted portion 100 slanted relative to a rotation direction of the rotation member 76. Therefore, when the agitation impeller vanes 15 having the slanted portion 100 are rotationally moved by rotation of the rotation member 76, ground formation soil can be forcibly moved by two surfaces of the slanted portion 100 slanted relative to the rotation direction of the rotation member 76. Thereby, the ground formation soil in contact with the agitation impeller vanes 15 is moved in a rotation direction and an axial direction of the rotation member 76, and accordingly ground agitation efficiency can be improved.SELECTED DRAWING: Figure 3
【課題】地盤の攪拌効率を向上させた攪拌翼及びこれを利用した機械攪拌工法を提供する。【解決手段】攪拌翼１４は、大略円筒状を成す回転部材７６と、回転部材７６の外周部に固定された複数の攪拌羽根１５とを含み、複数の攪拌羽根１５のうち少なくとも一部の攪拌羽根１５は、回転部材７６の回転方向に対して傾いた板状の傾斜部１００を有する。このため、回転部材７６の回転によって傾斜部１００を有する攪拌羽根１５が回転移動すると、回転部材７６の回転方向に対して傾いた傾斜部１００の２つの面によって、地盤形成土を強制的に移動させることができる。これにより、攪拌羽根１５と接触する地盤形成土が、回転部材７６の回転方向や軸方向に移動するため、地盤の攪拌効率を向上させることができる。【選択図】図３
