Description
Technical field
It the utility model is related to railway construction technical field, and in particular to a kind of combined type sound barrier.
Background technology
With the fast development of the high-speed railway in China, bullet train is by noise pollution caused by residential block, sternly
Along Railway resident normally work and rest are have impact on again, and it is an effective noise control measures to build sound barrier.
The widely used board plug type of high speed railway sound barrier built at present, i.e., line of high-speed railway installation uniformly away from
From H profile steel column, then place between column the polylith cell board of vertical combination.Structure per module unit plate is aluminium alloy face
Fiber cement board, sound-absorbing material and sound-absorbing material between plate, aluminum alloy back plate, aluminium alloy panel and aluminum alloy back plate fix dress
Put.The problem of prior art is present be：First, because aluminium alloy panel is straight, cell board lumen thickness is limited and fixed, centering
The acoustically effective of low frequency is poor；And the only sound insulation effect of the sound absorption of sound-absorbing material and fiber cement board, no scattering noise reduction shape
Formula, this causes its noise reduction to be unsatisfied with.2nd, the sound-absorbing hole in straight aluminium alloy panel is also easily floatd into rainwater, is easily caused
Sound-absorbing material shifts to an earlier date damp failure, both reduces noise reduction, increases later maintenance cost again.3rd, in straight aluminium alloy panel
The easy adhesive dust of sound-absorbing hole, the accumulation of dust can cause noise reduction to be deteriorated.
The content of the invention
The purpose of this utility model is according in place of above-mentioned the deficiencies in the prior art, there is provided a kind of combined type sound barrier, should
The features such as combined type sound barrier utilizes reflection, scatter attenuation and gel rubber material acoustic impedance are larger reduces the transmission of noise, has good
Good noise reduction.
The utility model purpose is realized and completed by following technical scheme：
A kind of combined type sound barrier, it includes frame plate and some sound insulation capsules, if offering dry hole on the frame plate
Hole, the sound insulation capsule are embedded inside described hole；It is described sound insulation capsule enclosure interior through two longitudinal baffles be divided into inner chamber,
Sap cavity and exocoel；Wherein, it is filled with sound-absorbing material in the inner chamber and the exocoel.
The both sides of the housing of the sound insulation capsule are fitted with sound absorption cloth.
Gel liquid is filled with the sap cavity, suspended particulate is mixed with the liquid.
The surface of two longitudinal baffles is irregular water wave curved surface.
Described hole is rectangle hole.
The utility model has the advantages that the sound insulation capsule in combined type sound barrier is declined according to Principles of Acoustics using reflection, scattering
Subtracting reduces the transmission of noise with gel rubber material acoustic impedance the features such as larger；Than traditional sound barrier, this sound barrier is not only in light weight,
It is firm in structure, also there is higher noise reduction efficacy.

Embodiment
Feature of the present utility model and other correlated characteristics are made further specifically by embodiment below in conjunction with accompanying drawing
It is bright, in order to the understanding of technical staff of the same trade：
Such as Fig. 1-5, mark 1-15 is respectively in figure：Frame plate 1, sound insulation capsule 2, hole 3, side plate 4, sound barrier 5, housing 6,
Absorb sound cloth 7, longitudinal baffle 8, inner chamber 9, sap cavity 10, exocoel 11, concrete bed 12, containing groove 13, elevating mechanism 14, vertical
Guide rail 15.
Embodiment：As shown in Fig. 1,3,4, the present embodiment is specifically related to a kind of combined type sound barrier, it include frame plate 1 with
And the capsule 2 that insulates against sound, some holes 3 are offered on frame plate 1, sound insulation capsule 2 is embedded inside hole 3；In the present embodiment, frame plate
1 is welded by two blocks of side plates 4, and two pieces of spacing of side plate 4 are separated by d；The rectangle hole of 3 rows 3 row is uniform-distribution with frame plate 1
3, each length of rectangle hole 3 is a, and width b, adjacent two rectangles hole 3 is at intervals of d；The edge of frame plate 1 reserves length
Spend the position for c；The inside of frame plate 1 and the edge for the capsule 2 that insulates against sound are closely chimeric, collectively form sound barrier 5.
As shown in Figure 1,5, the capsule 2 that insulates against sound includes housing 6 and is fitted in the sound absorption cloth 7 of the both sides of housing 6, and sound absorption cloth 7 is used for
Reduce the reflection of noise；Housing 6 is the rectangular body component made of magnesite material；Housing 6 be internally provided with two longitudinal directions every
Plate 8, two longitudinal baffles 8 will be separated into inner chamber 9, sap cavity 10 and exocoel 11 inside housing 6；In inner chamber 9 and exocoel 11
Filled with sound-absorbing material；Gel liquid is filled with sap cavity 10, the suspended particulate that size differs is mixed with liquid；When making an uproar
When sound passes through gel liquid, suspended particulate can cause noise that scatter attenuation occurs, so as to reach noise reduction；In the present embodiment
The surface of two longitudinal baffles 8 is irregular water wave curved surface, so that noise passes through and diffusing reflection can occur during longitudinal baffle 8 shows
As so that the absorption of noise that the sound-absorbing material in inner chamber can be evenly.
As shown in Figure 1, 2, the sound barrier 5 of the present embodiment is installed on concrete bed 12 along the railway, concrete bottom
Seat 12 offers the containing groove 13 of opening upwards；The liter for driving sound barrier 5 to lift is internally provided with containing groove 13
Descending mechanism 14；It is each provided with a vertical guide 15 in the open-topped both sides of containing groove 13, vertical guide 15 is along vertical
Direction offers the vertical groove being adapted with the edge of sound barrier 5；When the region where train drives into sound barrier 5, lift
Structure 14 jacks sound barrier 5 upwards from containing groove 13 so that sound barrier 5 enters working condition；After train sails out of, lifting
Mechanism 14 is shunk, and sound barrier 5 is dropped to inside containing groove 13, into off working state；Sound barrier 5 is using lift installation knot
Structure can avoid bearing nature wind load in off working state, reduce the fatigue damage of sound barrier 5, effectively extend sound
The maintenance cycle of barrier 5 and service life.
The advantageous effects of the present embodiment are：The sound insulation capsule of the present embodiment is declined according to Principles of Acoustics using reflection, scattering
Subtracting reduces the transmission of noise with gel rubber material acoustic impedance the features such as larger；Than traditional sound barrier, the sound barrier of the present embodiment is not
It is only in light weight, firm in structure, also there is higher noise reduction efficacy.
