Some solutions have been proposed in the prior art, the technical way of wherein road sqouynd absorption lowering noise is in road
Absorbent lined barrier is installed on both sides of the road, the material that absorbent lined barrier is used mainly includes glass, plastic cement, metal, rock cotton board, pearlite slab
Etc., but larger deficiency is all there is in actual use：For example, for glass, metal, plastic material, due to their materials
Matter is fine and close, and surface is smooth, thus seldom to the absorption of sound, and simply playing one to noise blocks, and substantial amounts of noise is still
To aerial diffusion, the effect of sqouynd absorption lowering noise is unsatisfactory, and metal and plastic cement it is outdoor it is lower exist be corroded and aging is asked
Topic, service life is shorter；And for rock cotton board, pearlite slab, although their porosity is higher, and acoustically effective is than fine and close material
The problems such as expecting to get well, but equally exist not high intensity, cracky and difficulty of construction, and can be flown away after rock cotton board weathering poisonous
Fibre dust, destroys surrounding environment.
Utility model content
For the disadvantages described above or Improvement requirement of prior art, the utility model provides a kind of platform sound-absorbing wall, wherein
By the targeted design in terms of the composition and its shape of key component and structure to its unitary construction, with prior art phase
Than that with compact conformation, construction, cleanliness without any pollution and intensity can be easy to high, resistance to while good sound absorption effect is provided
With property it is good the advantages of, be therefore particularly suitable for the application scenario of middle low speed magnetic suspension engineering etc.
To achieve the above object, according to the utility model, there is provided a kind of platform sound-absorbing wall, it is characterised in that the platform
Sound-absorbing wall is integrally provided in side of the platform wall towards the vehicles, and including outer panels, entodorsum, and it is arranged on the outside
Middle absorbent treatment between plate and the entodorsum, wherein：
Short transverse is provided with multiple projective structures on the outer surface of the outer panels, and these projective structures that
Transition is performed using planar structure between this；In addition, on the projective structure surface of itself and the planar structure table
Multiple sound-absorbing hole are offered on face；
The middle absorbent treatment is in cavity structure, and its inner containment has sound-absorbing material and keeps phase with the sound-absorbing hole
Connection.
As improvement project of the present utility model, above-mentioned platform sound-absorbing wall also includes air resonance layer, air resonance layer
It is arranged between the middle absorbent treatment and the entodorsum.
As improvement project of the present utility model, the projective structure is preferably triangular pyramids.
As improvement project of the present utility model, distribution of the projective structure in the outer panels is along short transverse
The mode submitted in density is arranged.
As improvement project of the present utility model, it is connected between the outer panels and the entodorsum using keel.
As improvement project of the present utility model, the highly preferred of the projective structure is set to 30mm~50mm；Institute
The thickness for stating middle absorbent treatment is set to 200mm~400mm.
In general, according to above technical scheme of the present utility model compared with prior art, can be tight with overall structure
Gather, be easy to the mode of construction to provide good sqouynd absorption lowering noise effect；Especially, in being entered by sound wave via a large amount of sound-absorbing hole
Between absorbent treatment and air resonance layer processing, test shows to may also provide high intensity, not cracky, clear while noise reduction is ensured
Clean pollution-free the advantages of, thus suitable for for example low speed magnetic suspension track, inter-city passenger rail, highway, city underground and
The application scenario of other civil buildings sound absorption formula partition wall etc.
Brief description of the drawings
Fig. 1 is the basic structure schematic diagram according to the platform sound-absorbing wall constructed by the utility model；
In all of the figs, identical reference is used for representing identical element or structure, wherein：
Absorbent treatment 3- entodorsum 11- projective structure 12- planar structure 5- platform walls in the middle of 1- outer panels 2-
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain
The utility model, is not used to limit the utility model.In addition, institute in each embodiment of the utility model disclosed below
As long as the technical characteristic being related to does not constitute conflict and can be just mutually combined each other.
Fig. 1 is the basic structure schematic diagram according to the platform sound-absorbing wall constructed by the utility model.As shown in figure 1, the station
Platform sound-absorbing wall is integrally provided in the side in the outside (for example towards all kinds of vehicles) of platform wall 5, and including outer panels 1, interior
