<p>PROBLEM TO BE SOLVED: To provide a pile capable of expecting an increase in pull-out resistance force from just after it, by applying required rotary operation to the pile pushed in the ground.SOLUTION: A lower end part 16 of a tilting anchor piece 15 is connected to an upper part of an overhang part 25 overhanging in a side surface part 13 of a pile body 6 pushed in the ground. The tilting anchor piece 15 can tilt in the downward direction from a standing state. When rotating the pile body 6 around its axis in a state of pushing the pile body 6 in the ground, the tilting anchor piece 15 tilts in the inverse direction of the rotational direction of the pile body 6 by resistance of soil. The tilting anchor piece 15 cuts in the soil in response to its tilting.</p> |
