PROBLEM TO BE SOLVED: To provide a rotary press-in device easy in carrying-in and assembling a device constituting member even in a narrow place and also extremely simple in a device configuration, and to provide a rotary press-in method capable of quickly rotation-pressing a reinforcement pile in a foundation even in the narrow place by using this rotary press-in device.SOLUTION: A rotary press-in device is constituted of: a steel pipe SP; motors 1 and 3 arranged so as to relatively freely advance/retreat in its inside and rotating a core rod K having an auger A on the tip; two leaders 4A and 4B extending in an extension direction of extending the steel pipe SP and the core rod K; and support legs 5A and 5B for supporting the two leaders 4A and 4B to the foundation G. The motors 1 and 3 freely move along the two leaders 4A and 4B, and the steel pipe SP and the core rod K advance while rotating by rotation by the motors 1 and 3 and the movement along the leaders 4A and 4B, and the foundation G is disturbed by boring the foundation G by the auger A, and the steel pipe SP is propelled into the foundation G, and the steel pipe SP is installed in the foundation. |
