To provide an excavation/agitation tool with a simple structure and low price capable of uniformly dispersing/scattering an improvement material in the whole area of an improvement diameter without affected by a size of an improvement diameter or ground quality and constructing an improvement body with good quality that is produced by uniformly agitating/kneading an improvement material and excavated/agitated soil.SOLUTION: An excavation/agitation tool comprises: an excavation/agitation shaft extending in a vertical direction; an excavation blade excavating a ground; a rectification body provided at a circumference end of the excavation blade; and a discharge port discharging an improvement material toward a rear space at a rear side of an excavation/rotation direction of the excavation blade that is partitioned by a plurality of faces including at least a rear face of the excavation blade and an inner face of the rectification body. The improvement material discharged from the discharge port can be guided to the whole area in a radial direction of the excavation blade by utilizing a rear flow of excavated soil flowing into a rear part beyond the rotating excavation blade.SELECTED DRAWING: Figure 1
【課題】簡素な構造且つ安価であるにも関わらず、改良径の大きさや地盤性質に左右されることなく改良径全域に改良材を均一に散布・拡散することができ、改良材と掘削・撹拌土を均一に撹拌混錬してなる良質な改良体を造成できる掘削・撹拌具を提供する。【解決手段】上下方向に伸延する掘削・撹拌軸と、地盤を掘削する掘削翼と、掘削翼の外周端に設けた整流体と、掘削翼の掘削回転方向後方側の、少なくとも、掘削翼の背面及び整流体の内面を含む複数の面によって区画される後方空間に向けて改良材を吐出する吐出口とを備え、吐出口から吐出された改良材を、回転する掘削翼を越えて後方へ流れ込む掘削土の後流を利用し、掘削翼の径方向全域へ誘導可能にした。【選択図】図１
