<p>PROBLEM TO BE SOLVED: To provide a vibro-hammer unit suitable for installing a medium-scale or small-scale pile and a wall body, by mutually connecting the shafts of vibro-hammers by a simple linkage member.SOLUTION: The vibro-hammer unit 10 is constituted of a base member 3, three or more of vibro-hammers 1A, 1B, 1C and 1D mounted on the base member 3 and one linkage member 2A, 2B and 2C (two or more of the linkage members as a whole) for connecting the shafts of two vibro-hammers among the three or more of vibro-hammers. In the two vibro-hammers mutually connected by the one linkage member, the shafts possessed by the two vibro-hammers are opposed, and the mutually opposed shafts are connected by the linear linkage members 2A, 2B and 2C, and all the two or more of linkage members 2A, 2B and 2C for mutually connecting the three or more of vibro-hammers 1A, 1B, 1C and 1D are arranged in the same direction.</p> |
