PROBLEM TO BE SOLVED: To provide an installation device and an installation method of a cylindrical pile with a moderate diameter.SOLUTION: Multiple vibration hammers comprise: a first and a second end vibration hammers 1, 2, which are individually installed near both ends of one diameter of a pile; and a first and a second intermediate vibration hammers 3A, 3B, the same amount of which are disposed in line along the one diameter of the pile on one semicircle SA and the other semicircle SB of the pile, respectively. Axes 1a, 2a, 1b, 2b at both terminals, which are most distant from the one diameter of the pile on the end vibration hammer, and axes at terminals, which are nearest to the one diameter of the pile on the intermediate vibration hammer, are disposed on a straight lines LA, LB, respectively. All sections between the end vibration hammers and two adjacent intermediate vibration hammers and between the intermediate vibration hammers are connected by linkages 5 each using a terminal axis disposed on the straight line as a link axis except for one section to be unconnected.SELECTED DRAWING: Figure 1 |
