PURPOSE:To perform a work to driven an oblique pile, by a method wherein the upper and the lower end of a guide beam are engagedly attached to each other through auxiliary ropes, and the inclining angle of a hammer is regulated through proper selection of the length of the auxiliary ropes. CONSTITUTION:A pile cap 20 and a hammer 4 are slidably mounted to a guide beam 19, and a pile guide 21 is mounted to the lower end of the guide beam 19. Auxiliary ropes 15 and 16 are engagedly attached to the upper and the lower end of the guide beam 19, the ropes 15 and 16 are engagedly attached to a hoist rope 14, and the inclining angle of a hammer 4 is decided through proper selection of the lengths of the ropes 15 and 16. A pile is engaged with the pile guide 21, a pile cap 20 is mated with the upper end of the pile, and the pile is driven by striking a hammer 4 with the aid of a starting device 23. Decision of an inclining angle through proper selection of the length of the auxiliary ropes causes facilitation of a work to driven an oblique pile through a simple device. |
