Abstract
The utility model discloses a railway roadbed abatvoix, including locate two between the track the intermediate mass and be located the limit piece of track both sides, the intermediate mass is that the surface is provided with banding recess, the intermediate mass bottom is equipped with two cavitys, intermediate mass and limit block list face have been covered with rule or anomalous arch, limit piece bottom is equipped with a cavity, and the both sides of limit piece are provided with the concave structure and the umbo structure of riveting mutually respectively. The utility model discloses a railway roadbed abatvoix's top layer designs into the strip recess, has utilized to inhale sound wedge principle on the acoustics, has guaranteed its absorbing effect, protruding structure has been add on the surface for the abatvoix surface has formed unevenness's structure, has further increased absorbing effect. The both ends of limit piece board are equipped with the unsmooth scarf joint structure that is used for the connection, the salient and the concave portion interlock each other of the adjacent board of being convenient for. There is the cavity below the abatvoix, constituted abatvoix resonance sound absorbing structure promptly, strengthen its absorbing effect, also provide the passageway to rainwater drainage in addition, be favorable to the drainage.
Description
Technical field
This utility model relates to damping and will make an uproar correlative technology field, is specifically related to a kind of railway roadbed abatvoix.
Background technology
Along with growth in the living standard and the development of science and technology, urban track traffic have also been obtained the biggest expansion,
Urban track traffic is often shuttled back and forth in dense population areas, and the vibration and the noise that produce during train driving have a strong impact on
The live and work of people.Being found through experiments, wheel-rail noise is the main source of track traffic noise,
Rail vibration is again the main aspect causing wheel-rail noise.Present track soundproof measures is the most in-orbit
Sound barrier is built on both sides, road, but this screen effect is limited.
Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, it is provided that a kind of railway roadbed abatvoix,
The noise that when can more effectively reduce train driving, track produces.
In order to reach the purpose of this utility model, technical scheme is as follows:
A kind of railway roadbed abatvoix, including the intermediate mass being located between two tracks and be positioned at track both sides
Limit block, it is characterised in that described intermediate mass is the groove that surface configuration has strip, described texturearunaperpendicular in or
Person is parallel to track length direction；Be provided with two cavitys bottom described intermediate mass, described cavity be perpendicular to or
It is parallel to track length direction；Described intermediate mass surface has been covered with regularly or irregularly protruding, described in
Between block rat equivalently-sized or different；A cavity, the both sides of limit block it are provided with bottom the block of described limit
Being respectively arranged with can the recessed structure of riveted and male structure mutually；Described limit block upper surface is also equipped with the recessed of strip
Groove；The surface of described limit block has also been covered with the projection of triangle, described limit block rat equivalently-sized or
Person is different.
Preferably, described groove is linear or waveform.
Preferably, the size between described intermediate mass rat is different；Between the block rat of described limit
Size is the most different.
This utility model has the advantages that
The Top-layer Design Method of railway roadbed abatvoix becomes equally spaced strip groove, make use of sound absorption wedge acoustically former
Reason, it is ensured that its sound-absorbing effect；And surface is additionally arranged bulge-structure so that abatvoix surface defines recessed
The structure of convex injustice, further increases sound-absorbing effect.
The two ends of limit block plate are provided with the concavo-convex joint construction for connecting, it is simple to the prominent and recess of adjacent panels
Divide and can be mutually twisted.There is cavity below abatvoix, i.e. constitute abatvoix resonance sound-absorbing structure, strengthen it
Sound-absorbing effect, the most also provides passage, beneficially draining to rainwater discharge.

Detailed description of the invention
Below in conjunction with embodiment, this utility model is further described, but protection domain of the present utility model is not
It is limited only to embodiment.
In conjunction with shown in Fig. 1 to Fig. 6, a kind of railway roadbed abatvoix, including intermediate mass 1 and limit block 2, intermediate mass
1, it to be located between two tracks, limit block 2 is arranged on track both sides, is respectively arranged with block 2 outside the track on both sides.
Intermediate mass 1 upper surface is provided with the groove 3 of strip, and described groove 3 is perpendicular to or is parallel to track
Length direction, in the present embodiment, the groove 3 of intermediate mass upper surface is parallel to the length direction of track.In
Between be provided with two cavitys 5 bottom block 1, cavity 5 is perpendicular to or is parallel to track length direction, in this reality
Executing in example, the groove 3 of intermediate mass upper surface is parallel to the length direction of track.Intermediate mass surface has been covered with rule
Then or irregular protruding 4, intermediate mass rat 4 is equivalently-sized or different, at the present embodiment
In, protruding 4 is the projection of triangle, and the size between the projection on intermediate mass 1 surface is different.
Also being provided with a cavity 5 bottom limit block 2, the both sides of limit block 2 are respectively arranged with can riveted mutually recessed
Structure 6 and male structure 7, laying when, be connected in series limit block 2 by recessed structure and male structure.
Described limit block 2 upper surface is also equipped with the groove 3 of strip.The surface of limit block 2 has also been covered with the convex of triangle
Play 4, limit block 2 rat equivalently-sized or different, in the present embodiment, limit block 2 surface convex
Size between Qiing is different.
The groove on intermediate mass 1 and limit block 2 surface is linear or waveform, in the present embodiment, is
Linear.
Size between the projection on intermediate mass surface from the projection on block surface, limit can also be identical or different.
Last it is noted that above example only in order to this utility model is described and and unrestricted practicality new
Technical scheme described by type, therefore, although this specification is new to this practicality with reference to each above-mentioned embodiment
Type has been carried out detailed description, but, it will be understood by those within the art that, still can be right
This utility model is modified or equivalent, and all are without departing from the skill of spirit and scope of the present utility model
Art scheme and improvement thereof, it all should be contained in right of the present utility model.
