摘要
An object of the present invention is to provide a method for constructing a rotary pile that can prevent damage to the rotary pile. In the method for constructing a rotary pile of the present invention, when the rotary pile provided with blades is penetrated into the ground, the fluctuation amount of the rotary pile and the rotational torque of the rotary pile are included during the rotary press-fitting of the rotary pile into the ground. A measurement process that measures pile information, a comparison process that determines whether the pile is normal or abnormal based on the relationship between rotational torque and eccentricity based on a preset threshold, and conditions for rotational press-fitting of the rotating pile based on the pile information. In the control step, the rotation torque of the rotary pile is reduced, or the rotation is stopped or reversed based on the result of the comparison step.
