Abstract:
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.
