<p>PROBLEM TO BE SOLVED: To provide a direction changing method of a pile rotary press-in machine and a pile rotary press-in machine reinstallation method of using its method, capable of easily changing the direction of the pile rotary press-in machine in the desired direction on the present ground together with a ruler member, without requiring a large type carrier such as a crane.SOLUTION: A direction changing method of a pile rotary press-in machine 10 includes: an underframe 1; a lifting driving device 2; a lifting frame 3 liftable to the underframe 1 by the device 2; a rotational driving device 4 mounted on the lifting frame 3 and; a pile gripping mechanism 5 rotatingly drivable to the lifting frame 3 by the device 4, and a support column 8 is erected, and the lifting frame 3 is pulled up from the underframe 1, and the underframe 1 is pulled up together with a ruler member 6 with the support column 8 as a support, and the pile rotary press-in machine 10 is changed in the direction by relatively rotating the lifting frame 3 by the rotational driving device 4. The direction-changed pile rotary press-in machine 10 is moved and reinstalled by using the ruler member 6.</p> |
