To acquire soil information of the ground while performing excavation operation at a work site.SOLUTION: A hydraulic shove comprises a work attachment, a driving part 71, a load cell 61, a mechanical load calculation section 503, a soil pressure load calculation section 504, and a soil property estimation section 505. A mechanical load calculation section 503 calculates a mechanical load as a load from sediment received by a bucket based on posture information of the work attachment 20 and information relating to a load received by the driving part 71. The soil pressure load calculation section 504 calculates a soil pressure load as a load applied by clod on the bucket through a shape of the clod formed by the soil retained with the bucket, the posture information, a shape of the bucket, soil density, and a wall surface friction angle between the soil and the bucket. The soil property estimation section 505 estimates soil property at the work site based on the machine load and the soil pressure load.SELECTED DRAWING: Figure 2
【課題】作業現場において掘削作業を行いながら地盤の土質情報を取得する。【解決手段】油圧ショベルは、作業アタッチメントと、駆動部７１と、ロードセル６１と、機械負荷演算部５０３と、土圧負荷演算部５０４と、土質推定部５０５とを備える。機械負荷演算部５０３は、作業アタッチメント２０の姿勢情報および駆動部７１が受ける負荷に関する情報から、バケットが土砂から受ける負荷である機械負荷を演算する。土圧負荷演算部５０４は、バケットによって堰き止められた土によって構成される土塊の形状、前記姿勢情報、バケットの形状、土の密度、土とバケットとの壁面摩擦角から、前記土塊がバケットに付与する負荷である土圧負荷を土圧論に基づいて演算する。土質推定部５０５は前記機械負荷と前記土圧負荷とに基づいて作業現場における土の土質を推定する。【選択図】図２
