ANCHOR PILE AND CONSTRUCTION METHOD THEREOF
To provide an anchor pile that can exhibit a desired pull-out resistance regardless of the state of the soil.SOLUTION: An anchor pile 10 comprises a pile body 11 whose lower side is buried in the ground, a movable protrusion 12 that can protrude outward of the pile body 11 through a protrusion opening 11c provided on a lower outer surface of the pile body 11, and an operation shaft body 13 inserted into an inside of the pile body 11 from the operation shaft body insertion port 11b provided in an upper portion of the pile body 11. By forming a plurality of tooth portions α on a proximal end side of a movable protrusion 12 and forming a plurality of tooth portions β on an outer peripheral surface of the operation shaft body 13, when the operation shaft body 13 is inserted and lowered into the pile body 11 from the operation shaft body insertion port 11b, the tooth portion α and the tooth portion β mesh with each other, and the downward movement of the operation shaft body 13 is converted into the rotational movement of the movable protrusion 12, and the movable protrusion 12 rotates in an upright manner and protrudes outward from the protrusion opening 11c.SELECTED DRAWING: Figure 6
【課題】土の状態等にかかわらず、所望の引き抜き抵抗を発揮することができるアンカー杭を提供する。【解決手段】アンカー杭１０を、その下側が地中に埋設される杭本体１１と、杭本体１１の下側外面に設けられた突出体用開口部１１ｃを通じて杭本体１１の外方に突出可能な可動突出体１２と、杭本体１１の上部に設けられた操作軸体用挿入口１１ｂから杭本体１１の内部に挿入される操作軸体１３とで構成し、可動突出体１２の基端側に複数の歯部αを形成するとともに、操作軸体１３の外周面に複数の歯部βを形成することにより、操作軸体１３を操作軸体用挿入口１１ｂから杭本体１１の内部に挿入して下降させると、歯部αと歯部βとが噛み合って操作軸体１３の下降移動が可動突出体１２の回転移動に変換され、可動突出体１２が起立回転して突出体用開口部１１ｃから外方に突出するようにした。【選択図】図６
