PROBLEM TO BE SOLVED: To provide a steel pipe pile capable of improving a ground supporting force at a low cost by simple means without impairing workability.SOLUTION: A steel pipe pile 1 has a shaft part 2 made of a steel pipe. A circular end face plate 3 with a diameter D larger enough than a diameter d of the shaft part 2 is welded on an apical surface of the shaft part 2. The steel pipe pile has a flange part 4 protruding outward beyond the shaft part diameter of the end face plate. The flange part has a cutout part 5 in a direction from a circumference of the end face plate to a center. Inclined face parts 6 and 7, which are inclined in vertically opposite directions to each other, are formed at both sides in a circumferential direction of the end face plate of the cutout part 5. A concavity 8, which is dented toward the pile head side, is formed on a central part of the end face plate 3.SELECTED DRAWING: Figure 2 |
