<p>PROBLEM TO BE SOLVED: To provide an anchor pile capable of restraining reduction in bearing force by a shear load.SOLUTION: An anchor pile 1 comprises an anchor member 3 buried in the ground from the tip side and an extension rod 5 connecting one end part to a rear end part of the anchor member 3, in which the anchor member 3 is buried in the ground by rotating the other end part of the extension rod 5 connected to the anchor member 3 around the axis of the extension rod 5 by an auger 9. The anchor member 3 comprises a first excavation blade 32 formed in a spiral shape toward the axial direction and a head part 34 for installing the extension rod 5. The extension rod 5 comprises a second excavation blade 53 formed in a spiral shape toward the axial direction and a connection part 51 connected to the head part 3. The head part 34 and the connection part 51 are connected in a state of loosely fitting one to the other, and engage with each other by rotation of the auger 9, thereby transmitting driving force of the auger 9 to the first excavation blade 32.</p> |
