Claims (1)

【実用新案登録請求の範囲】 拡孔装置本体の内部に、 −先行ポーリング用ビットを兼ねた板状の拡孔ウィング
の中心を旋転自在にピン軸正し、この板体をピン軸を中
心に回転させることにより、 板体の約半分が本体の先端から露出した状態で板体を本
体軸線方向に収納することと、板体を本体軸線とほぼ直
角方向に旋転することを可能にしたことを特徴とした、 地盤改良等に使用する拡孔装置。[Claim for Utility Model Registration] Inside the hole punching device main body: - The center of a plate-shaped hole punching wing that also serves as a bit for advance polling is rotatably aligned with the pin axis, and the plate body is rotated around the pin axis. By rotating it, it is possible to store the plate in the direction of the axis of the main body with about half of it exposed from the tip of the main body, and to rotate the plate in a direction almost perpendicular to the axis of the main body. Features: A hole-expanding device used for ground improvement, etc.
