PURPOSE:To perform easy inclining and holding of a pile holder, by a method wherein a forward and backward movable support beam, a lateral runnable traversing truck, and an inclibale pile holder are supported to the forward end of a platform. CONSTITUTION:A pile 3 on a platform 9 is supported to a pile holder 15 with the aid of a crane 11, and the driving position and attitude of the pile 3 are determined through forward and backward movement of a support beam 12, traversing of a lateral running truck, and inclination of a pile holder 15. A hammer 4 is moved from a containing stand 17 to the upper part of the pile 3. The lengths of auxiliary ropes 18 and 19 are regulated, the attitude of the hammer 4 is caused to coincide with the inclining angle of the pile 3, and the pile 3 is driven through driving of the pile 4. After driving of the pile 3 is completed, a running device 8 is driven, and the platform 9 is moved forward to a position above the pile 3. This enables the pile to be easily inclined and held in any direction with the aid of the support beam 12, the traversing truck, and the pile holder 15. |
