ROTARY PRESS-IN DEVICE OF STEEL PIPE PILE WITH BLADE AND INSTALLING METHOD FOR STEEL PIPE PILE WITH BLADE IN ROTARY PRESS-IN DEVICE

PROBLEM TO BE SOLVED: To provide a rotary press-in device capable of safely installing a steel pipe pile with blades, by avoiding expanding an inner diameter of a chuck. SOLUTION: This rotary press-in device has a driving device for rotating a chuck device, by rotatably supporting the chuck device having an inner diameter a little larger in a diameter than a body part of the steel pipe pile with the blades by a lifting frame, by liftably drivably supporting the lifting frame having a wide opening capable of inserting-extracting the blades in a substantially central part by press-in cylinders, by erecting a plurality of press-in cylinders on a base frame having a wide opening capable of inserting-extracting the blades of the steel pipe pile with the blades in a substantially central part. In the rotary press-in device of the steel pipe pile with the blades, the chuck device is freely attached to and detached from the lifting frame, and after removing the chuck device from the lifting frame, the respective wide openings of the lifting frame and the base frame are faced.
