打機を使用することになる。By the way, in a pile driver, it is necessary to lower the auger drive unit near the ground surface in order to increase the excavation length with a short leader. Since it can move only to the lower end of the pipe and cannot approach the ground surface closest, there is a limit to the descent of the auger drive device. Therefore, if a long leader and a long auger screw or casing are used, a large pile driver will be used to ensure stability.

ができる。With this configuration, from the state in which the lower guide 14 during normal excavation work shown in FIG. 4 is slightly lifted from the ground surface, the rod 11a of the hydraulic cylinder 11 is extended as shown in FIG. The auxiliary reader 12 with the attached 14 is lowered and grounded, the auxiliary reader 12 is used as a front jack, the lower guide 14 can be brought closest to the ground surface, and the auger driving device 5 can be moved to the lowermost end of the guide pipe 7. The excavation work can be performed by lowering it. Therefore, the lifting stroke of the auger driving device 5 is increased, the excavation length can be increased with a short leader, and the length of the auger screw and the casing can be short. The performance is improved.
Therefore, a small pile driver 1 can be used. Further, since the lower guide 14 is detachable from the auxiliary reader 12, the lower guide 14 can be removed at the time of transportation or the like.
