PURPOSE:To reduce the vibration propagation rate of machinery by making up the foundation of machinery from fixed piles, friction piles, a concrete superstructure, a flexible tube, side rubber plates, vibration-proof sand, a concrete substructure, and upper rubber plates. CONSTITUTION:The foundation of a machinery consists of plural fixed piles 11, plural friction piles 12, a concrete substructure 13, a flexible tube 14, side rubber plates 15, vibration-proof sand 16, a concrete superstructure 17, and upper rubber plates 18. Vibration caused by machinery is orderly damped by the upper rubber plates 18, the concrete superstructure 17, vibration-proof sand 16, and the friction piles 12 and transmitted to the ground. The vibration from the concrete superstructure 17 and the vibration-proof sand 16 is absorbed by the side rubber plates 15 and the concrete substructure 13. Only the damped vibration is transmitted to the ground. |
