GROUND AGITATION MIXING APPARATUS AND SOIL IMPROVEMENT METHOD
PROBLEM TO BE SOLVED: To provide a structurally-simple ground agitation mixing apparatus that dispenses with the whole or a part of a corotation prevention plate, and a ground agitation mixing method that makes resistance during ground penetration low.SOLUTION: An agitation mixing apparatus 1A includes: an agitation shaft 2; a drilling blade 3 that is formed on a lower part of the agitation shaft 2; and single blades 4a-4d that are extended in one direction from the four-level agitation shaft that is formed above the drilling blade 3. The drilling blade 3 is a single blade or two blades having a bit (excavation blade) for excavating ground. The one or more agitation shafts are provided.SELECTED DRAWING: Figure 1
【課題】共回り防止板の全部又は一部を不要とする構造が簡単な地盤攪拌混合装置及び地盤貫入時の抵抗が少ない地盤攪拌混合方法を提供する。【解決手段】攪拌混合装置１Ａは、攪拌軸２と、攪拌軸２の下部に形成される掘削翼３と、掘削翼３の上方に形成される４段の攪拌軸から一方向に延びる片翼４ａ〜４ｄを有する。掘削翼３は、地盤を掘削するビッド（掘削刃）を有する片翼又は２枚翼であり、攪拌軸は１軸又は２軸以上である地盤攪拌混合装置。【選択図】図１
