となる。However, in the above-mentioned method of rotating a steel pipe pile having a penetrating wing attached to the tip by an auger machine, rotational driving energy is largely consumed on the way due to friction between the steel pipe pile and the ground. It is necessary to rotate the steel pipe pile with a large torque, and there is a problem that the auger machine becomes large. When the diameter of the foundation pile is large, when the length of the foundation pile is long, or when the foundation pile is cast on hard ground, a large amount of torque is required, and construction is difficult.

However, according to the present invention, since only a rotary penetrating body rotatably mounted at the tip of a hollow pile such as a steel pipe pile is rotationally penetrated, the pile can be penetrated and driven with a relatively small torque. Becomes Also, since the hollow pile does not receive a large torque for rotary excavation,
There is no risk of damage to the hollow pile due to torsional moment,
It is also possible to use a concrete pile for the hollow pile.
