PROBLEM TO BE SOLVED: To provide an excavation-agitation device having a constitution capable of improving fragmentation performance for fragmenting a clod and agitation performance for agitating excavation earth and a ground solidification material.SOLUTION: An excavation-agitation device comprises a cylindrical shaft part, an excavation blade provided in a tip part of the shaft part, an agitation blade provided on the base end side of the shaft part more than the excavation blade and a corotation prevention part relatively rotatably installed to the shaft part in a position of separating a predetermined clearance to the agitation blade in the axial direction of the shaft part and extending up to the outside more than the excavation blade in the radial direction of the shaft part, and the corotation part comprises a plurality of through-holes of penetrating in the axial direction.SELECTED DRAWING: Figure 1
【課題】土塊を細分化する細分化性能、並びに掘削土及び地盤固化材を攪拌する攪拌性能を向上可能な構成を有する掘削攪拌装置を提供すること。【解決手段】筒状の軸部と、前記軸部の先端部に設けられた掘削翼と、前記掘削翼よりも前記軸部の基端側に設けられた攪拌翼と、前記軸部の軸方向において前記攪拌翼と所定の間隙を隔てた位置に、前記軸部に対して相対的に回動可能に取り付けられると共に、前記軸部の径方向において前記掘削翼よりも外側まで延在する共回り防止部と、を備え、前記共回り防止部は、前記軸方向に貫通する複数の貫通孔を有している。【選択図】図１
