Description
Technical field
The utility model relates to a kind of vibration isolation panel assembly that is suitable for earthen foundation that can be widely used in neighboring buildings vibration isolation in a series of civil engineerings such as dynamic consolidation construction, explosion, track traffic.
Background technology
In industrial production, often there are the three class vibration sources that vibration effect worsens environment.
The first kind is transient state vibration source, and as the explosive dropping hammer in hammering ground, blasting works in strong rammer operation discharges chemical energy etc., these vibration sources belong to the formula of rushing and clash into, and vibration source vibrational energy is very large, and spectral band is wider, and influence basin is very wide.
Equations of The Second Kind is stable state vibration source, as air compressor machine, vibrosieve, and refrigeration compressor, blower fan, water pump etc., these vibration sources belong to regular cycle repeated action.
The 3rd class is randomness vibration source.Mainly contain train, automobile, crane and lathe class, these vibration sources are because being subject to probabilistic dominance, and its vibration processes is assumed to be ergodic random process stably.Wherein train vibration energy is larger, and scope impact is wider.
There is corresponding vibration effect and harm in above-mentioned three class vibration sources, needs to treat in earnest in engineering design, and appropriate taking appropriate measures solved.How wave energy is effectively intercepted, reduce it is that engineering circles and academia endeavour the problem solving near impact of constructing and infringement always.
At present, in the middle of Practical Project, the general barrier vibration isolation technology that adopts arranges one vibration isolation barrier, to block the propagation of wave energy (especially ground roll) between vibration source and protected target.The mode of barrier vibration isolation is a lot, but from vibration isolation mechanism, what effect was best is to use open drain vibration isolation, and it allows wave energy transmission hardly.But because open drain easily caves in, poor durability, and it is dumb to cause place to use, so in Practical Project, apply less, generation be the filling ditch getting up with various material fillings.Conventional filler has flyash, concrete, gravel etc. at present.Facts have proved, the vibration isolating effect of flyash is undesirable, and utmost point proportioning is difficult to grasp, and long-term vibration isolating effect is poorer; Concrete filling ditch cost is too high, very uneconomical.Generally speaking, dig on a wide area vibration isolate ditch earth volume is large, wastes time and energy; And due to needs filler, vibration isolating effect is also not fully up to expectations.
