Discontinuous vibration damping and isolating device and formation method
The invention discloses a discontinuous vibration damping and isolating device and a formation method. The discontinuous vibration damping and isolating device comprises two rows of vibration isolating holes, bellows are arranged in the vibration isolating holes, and filler is packed between the bellows and the vibration isolating holes. The formation method includes that the vibration isolating holes are arranged between a protected building and a vibration source and distributed in a staggered manner. The diameter and the depth of the vibration isolating holes are adjusted according to the strength of the vibration source. EPS (expandable polystyrene) fiber mixed light soil is filled between the inner walls of the vibration isolating holes and the bellows can protect stability of the vibration isolating holes. Meanwhile, wave impedance ratio among different medium contact surfaces is increased, and energy of transmitted waves is reduced. In addition, a reinforced concrete sheet can be erected at the tops of the vibration isolating holes and covered with backfill for planting flowers and plants, so that the discontinuous vibration damping and isolating device is economic, environment friendly and efficient. The discontinuous vibration damping and isolating structure can effectively reduce adverse effects on the important protected buildings and precise instruments from traffic load vibration.
