Zusammenfassung:Provided are a rotary pile construction method which can prevent sediment from clogging a rotary pile, when the rotary pile is rotatingly pressed into the ground, and a rotary pile.　A construction method in which a rotary pile 17 provided with a blade 16 is penetrated into the ground 91 is characterized by including: a measurement step for measuring an vertical load in the rotary pile 17, while the rotary pile 17 is rotatingly pressed into the ground 91; and a determination step for determining whether to clear the clogging of sediment accumulated in the rotary pile 17 on the basis of the measurement result obtained from the measurement step. In addition, the measurement step is characterized by including measuring at least any one among the rotational torque and a penetration amount of the rotary pile 17.
