EXPLORATION DEVICE AND EXPLORATION METHOD FOR GROUND SAMPLE

To provide an exploration device and an exploration method for ground samples that can suppress the disturbance of a core.SOLUTION: A ground sample exploration device 1A comprises a penetration device 20 for penetrating a core tube 200 into the ground G, an excavator 30 that excavates an annular hole H for exploration of the ground by digging in a ring shape around the intrusive core tube of the ground in the intrusive direction of the core tube, and an exploration unit 40 that is placed inside the excavated annular hole for exploration and is capable of exploring the ground sample inside the core tube.SELECTED DRAWING: Figure 1 【課題】コアの乱れを抑えることができる地盤試料の探査装置及び探査方法を提供する。【解決手段】地盤試料の探査装置１Ａは、コアチューブ２００を地盤Ｇに貫入させるための貫入装置２０と、地盤の、貫入されたコアチューブの周囲を環状に、コアチューブの貫入方向に掘進して地盤の探査用環状孔Ｈを掘削する掘削装置３０と、掘削された探査用環状孔の内部に配置されて、コアチューブの内部の地盤試料を探査可能な探査ユニット４０と、を備える。【選択図】図１
