ATTACHMENT AND CRUSHED STONE PILE FORMING DEVICE INCLUDING THE SAME
To provide an attachment and a crushed stone pile forming device including the same, capable of reducing maintenance cost caused by wear on a cylindrical part.SOLUTION: An attachment 10 for forming crushed stone pile comprises: a cylindrical part 12 in which a crushed stone charging hole 15 is formed; and a door 20 attached on the cylindrical part 12 to open/close the crushed stone charging hole 15. The cylindrical part 12 is connected to a driving device 11 generating rotational driving force to form a space by excavating the ground through the rotational driving force. The cylindrical part 12 comprises: a plurality of cylindrical parts 12A, 12B; and one or a plurality of connection mechanisms 61 separably connecting the cylindrical parts 12A, 12B adjacent to each other in an axial direction. The plurality of cylindrical parts 12A, 12B comprise crushed stone charging hole parts. The crushed stone charging hole 15 is configured with the crushed stone charging hole parts formed in the plurality of cylindrical parts 12A, 12B. At least one of one or the plurality of connection mechanisms 61 are provided on inner peripheral surfaces of the two cylindrical parts 12A, 12B connected by the connection mechanisms 61.SELECTED DRAWING: Figure 1
【課題】円筒部の摩耗により発生するメンテナンスコストを低減する。【解決手段】砕石杭形成用のアタッチメント１０は、砕石投入孔１５が形成される円筒部１２と、円筒部１２に取付けられ砕石投入孔１５を開閉する扉２０とを備える。円筒部１２は、回転駆動力を発生させる駆動装置１１に接続され、回転駆動力により地中を掘削して空間を形成する。円筒部１２は、複数の円筒部分１２Ａ、１２Ｂと、軸方向に隣接する円筒部分１２Ａ、１２Ｂを分離可能に連結する１又は複数の連結機構６１とを備える。複数の円筒部分１２Ａ，１２Ｂは、砕石投入孔部分を備える。砕石投入孔１５は、複数の円筒部分１２Ａ，１２Ｂに形成された砕石投入孔部分により構成される。１又は複数の連結機構６１の少なくとも一つが、当該連結機構６１が連結する２つの円筒部分１２Ａ、１２Ｂの内周面に設けられている。【選択図】図１
