状杭。 At the center of the head of the pile body, which has spiral blades on the outer periphery,
In a threaded pile provided with an engagement hole that engages with a power shaft for applying rotational torque to the pile body, the engagement hole extends along the body of the pile body to near the tip of the pile body. What is claimed is: 1. A screw-shaped pile, characterized in that it is formed of a tubular body with a threaded structure and a reinforcing member is provided at the distal end of the tubular body, the reinforcing member extending close to the most distal end of the pile body.
