PURPOSE:To simplify the structure of a high-speed impact hammer as well as enhance the efficiency of striking by connecting a tamper to an impaction generator through a guider with a spring and an anvil to buffer the impaction of an impact hammer to be used in consolidation work. CONSTITUTION:A high-speed impact hammer to be used in a consolidation work for improving the ground consists of an impaction generator 1 worked by a drive source 2, e.g., an oil-pressure motor, etc., a striking head 4 provided projectionally through the supporting plate 3 at the lower end of the generator 1, a tamper 5 of a truncated form supported through a supporting plate 3, a guide rod 7, and compressive spring 9, and an anvil 6 to buffer the impact head 4 provided between the lower part of the impactor 1 and the tamper 5 by means of a buffer material 11. A high-speed impact hammer having a simplified constitution and a high striking efficiency, which can be used even in leveling rubbles, can be obtained. |
