To provide a construction method for a rotary press-in pile with tip chips, and the rotary press-in pile with the tip chips suitably used therefor requiring no much time and labor for preparing a test, reducing a construction cost, generating little noises and vibration, and allowing sure construction in response to a construction site undulating in the support ground and an unexpected difference in an earth layer.

This construction method rotatably presses a rotary press-in pile having inclined chips in prescribed ground of the underground in conformity with a press-in speed in a tip part of a rotary press-in pile body. A rotational torque value, press-in pressure and a rotating speed with every depth are detected when rotatably pressing in the rotary press-in pile up to the prescribed depth, and construction time frictional force of the rotary press-in pile and an earth layer with respective depths is calculated from detected these data, and is displayed. Construction is performed while confirming and controlling so that this calculated construction time frictional force exceeds design frictional force.
