A plurality of such eccentric rotating bodies are provided on the circumference of the hiring pile. And, when the foundation pile is penetrated into the ground, if the earth pressure that resists the progress of the pile is configured to act in a direction that causes the eccentric rotating body to bite into the outer diameter surface, when the pile penetrates into the ground, hiring is performed. The pile holds the foundation pile firmly. When the pile entry process is completed, operating the operating rod from the ground to apply a force in the direction away from the outer diameter surface of the pile, the engagement between the hired pile and the foundation pile can be made with one touch. Can be canceled. It is preferable that a ring-shaped groove into which the eccentric rotating body fits is provided on the outer diameter surface of the foundation pile because the engagement is further ensured.

である。On the other hand, the reinforcing metal 2 is provided on the outer periphery of the foundation pile 20.
1 is provided. The eccentric rotating body 6 is provided with a pin 10 for rotating the eccentric rotating body 6 around the pin 5, and the pin 10 is connected to the operating rod 9 via a connecting bracket 8. In the embodiment of FIG. 1, when the operating rod 9 is pulled up, the eccentric rotating body 6 rotates about the pin 5 and bites into the outer diameter surface of the foundation pile 20. When the eccentric rotary body 6 engages with this outer diameter surface, the hiring pile 1
And the foundation pile 20 are firmly connected. Conversely, when the operating rod 9 is pushed down in the direction of the arrow 11, the connection between the hire stake 1 and the foundation stake 20 is easily released. When the pile enters the ground, the earth pressure acts in the direction in which the operating rod is pulled up, so that the hiring pile securely holds the foundation pile, which is convenient. In addition,
It is more effective if the ring groove 22 is provided on the outer diameter surface of the foundation pile as shown in FIG. 2 so that the profile 7 of the eccentric rotating body 6 abuts.
