Description
Technical field
The present invention relates to building structure field, be specifically related to a kind of vibration isolation barrier based on foam core wave resistance plate.
Background technology
Along with developing rapidly of Urbanization Construction and modern industry, various problem of environmental pollutions are day by day frequent, the most manually
The problem of environmental pollution that vibration causes causes the extensive concern of various circles of society.The environmental pollution that artificial vibration causes includes ground
Surrounding enviroment vibration, ground long-term settlement and the sound pollution etc. of vibration induction.Ground be by vibration from artificial vibration source to week
The main intermediate medium that surrounding environment is propagated, the surrounding enviroment vibration caused by ground is the main path that artificial vibration is polluted.
The living and working environment of foundation vibration building, underground utilities, precision instrument and equipment and people to closing on has can not neglect
Depending on impact.
The Main Means solving ambient vibration the most both at home and abroad is barrier vibration isolation.The principle of barrier vibration isolation is built upon ripple
On the basis of reflection, scattering and diffraction, its essence is elastic wave about multiple heteroplasmonic multiple scattering problems, i.e. at vibration source and
Between protection target, one vibration isolation barrier is set, to block the propagation of wave energy (especially face ripple).Barrier is divided into continuous barrier
With discontinuous barrier two kinds.Continuous barrier is the forms such as free ditch, bentonite slurry, concrete core wall, flyash；Noncontinuity screen
Hinder the forms such as porose row, concrete single-row stake, multiline pile.From the point of view of vibration isolation mechanism, effect most preferably uses empty ditch vibration isolation, and it is several
Do not allow wave energy transmission.But owing to empty ditch easily caves in, poor durability, and also it is dumb to cause place to use, so in reality
Border engineering is applied less, instead of be the filling ditch got up with various material fillings.The most conventional filler has fine coal
Ash, concrete, gravel etc..It was verified that the vibration isolating effect of flyash is undesirable, level proportioning is difficult to grasp, long-term vibration isolating effect
Worse；Concrete filling ditch cost is the highest, the most uneconomical.Sum it up, large area excavation vibration isolation ditch earth volume is big, time-consuming take
Power；And due to needs filler, vibration isolating effect is the most not fully up to expectations.
Summary of the invention
In order to reduce traffic loading, as train, automobilism vibration etc. on roadside works and the impact of resident, carry
Gone out a kind of vibration isolation barrier based on foam core wave resistance plate, i.e. road or track and by protection works between place in
The sandwich wave resistance plate of embedding certain thickness, width and the degree of depth, carrys out, with this, the harm that slowing down vibration is brought.
For achieving the above object, the technical scheme that the present invention takes is:
A kind of vibration isolation barrier based on foam core wave resistance plate, including the first plain concrete plate, the second plain concrete plate and
Cystosepiment, cystosepiment is clamped between the first plain concrete plate and the second plain concrete plate.
Wherein, described first plain concrete plate, the second plain concrete plate select strength grade to be the concrete of C15-C30.
Wherein, described cystosepiment is polystyrene foam plate, has another name called cystosepiment, EPS sheet, is to be sent out by containing volatile liquid
The expandable polystyrene bead of infusion, the white object of hot briquetting in a mold after heated pre-, it has fine closed pore
Construction features.
Wherein, should be according to condition design wave resistance plates such as the speed of dynamic load, amplitude and frequency of vibration in concrete application
And the thickness of laminboard layer, the buried depth of wave resistance plate and width；When carrying out the design of sandwich wave resistance plate, for ensureing different soil
Vibration isolating effect under matter, vibration condition all can reach more than 50%, according to taking of conservative situation, sandwich wave resistance board size and buried depth
Value scope is: away from the bottom of foundation degree of depth (0.01～0.06) λR, sandwich wave resistance plate length or width (0.5～1) λR, λRFor Rayleigh wavelength.
The method have the advantages that
Can the impact of effective slowing down vibration harm, be effectively reduced vibration output, reduce shaking of being brought of traffic loading
Dynamic harm, reaches preferable vibration isolating effect.Compare more other kinds of vibration isolation barrier and have that cost is low, be hardly damaged, construct simple
Etc. advantage, design relatively flexible simultaneously, can be according to the ripple of the flexible design difference laminboard layer thickness such as the extraneous frequency of load, amplitude
Baffle-wall.Meanwhile, the present invention also has that material source is sufficient, vibration isolating effect is good, protects after and construction little to the restriction of the barrier degree of depth
Hold Land leveling, do not affect the advantages such as environmental beauty.
