ATTACHMENT FOR FORMING CRUSHED STONE PILE, AND FORMING DEVICE OF CRUSHED STONE PILE INCLUDING THE SAME
To make it possible to easily throw-in crushed stone into an inside of a cylindrical portion, by restraining a cylindrical portion from rotating in a normal rotation direction when throwing-in crushed stone.SOLUTION: An attachment for forming a crushed stone pile comprises: a cylindrical portion whose side face has holes for throwing-in crushed stone formed along an axial direction; a spiral portion rotatably disposed in the cylindrical portion, connected to a driving device generating a rotational driving force in a normal rotation direction and in a reverse rotation direction, excavating underground by rotating in the normal rotation direction, and applying pressure to the crushed stone by rotating in the reverse rotation direction; a rotational driving force transmitting portion transmitting the rotational driving force in the normal rotation direction to the spiral portion and the cylindrical portion when the driving device generates the rotational driving force in the normal rotation direction and transmitting the rotational driving force in the reverse rotation direction to the spiral portion when the driving device generates the rotational driving force in the reverse rotation direction; and a reverse rotation preventing portion restraining rotation of the cylindrical portion in the reverse rotation direction and restraining rotation of the cylindrical portion in the normal rotation direction when the driving device generates the rotational driving force in the reverse rotation direction.SELECTED DRAWING: Figure 9
【課題】砕石投入時に円筒部が正転方向に回転することを規制することで、円筒部内への砕石投入を容易に行うことを可能とする。【解決手段】砕石杭形成用のアタッチメントは、その側面に軸方向に沿って砕石投入孔が形成される円筒部と、円筒部内に回転可能に配置されており、正転方向と反転方向の回転駆動力を発生させる駆動装置に接続されており、正転方向に回転することで地中を掘削し、反転方向に回転することで砕石に圧力を印加する螺旋部と、駆動装置が正転方向の回転駆動力を発生させると螺旋部及び円筒部に正転方向の回転駆動力を伝達し、駆動装置が反転方向の回転駆動力を発生させると螺旋部に反転方向の回転駆動力を伝達する回転駆動力伝達部と、駆動装置が反転方向の回転駆動力を発生させるときに、円筒部の反転方向の回転を規制すると共に、円筒部の正転方向の回転を規制する反転防止部と、を備える。【選択図】図９
