PROBLEM TO BE SOLVED: To provide a strong and inexpensive pile and a manufacturing method therefor.SOLUTION: A pile 1 is made by connecting a stiletto-shaped implanted member 20 to a tip of a squeezed part 12 at which an outer shape tapers toward a tip at one end of a single pipe 10. The pile 1 is manufactured by the following processes: a squeezed part forming process to form the squeezed part 12 at which the outer shape tapers toward the tip by forming multiple push-in parts 11 at which one end of the single pipe 10 is pushed inward at the end of the single pipe; and a tip forming process to connect the stiletto-shaped implanted member 20 is connected to the tip of the squeezed part 12.SELECTED DRAWING: Figure 1 |
