Abstract

The utility model discloses a sound absorbing wall, which has the advantage of being capable of effectively eliminating noise pollution. The sound absorbing wall comprises a sound-absorbing cotton layer, a front compression plate and a rear compression plate, wherein the front compression plate is arranged on the front face of the sound-absorbing cotton layer and the rear compression plate is arranged on the back face of the sound-absorbing cotton layer; and channels communicated with the sound-absorbing cotton layer are formed in the front compression plate. Through arranging the sound absorbing wall disclosed by the utility model at both sides of highways/railways, when automobiles/trains pass through the highways/railways, produced noises can enter the sound-absorbing cotton layer through the channels and be effectively absorbed, so that noises around the highways/railways can be greatly reduced, the normal rest of residents nearby the highways/railways is favored, and then, the sound absorbing wall is applicable to the popularization and application in various occasions where noise pollution is produced.

Description

Sound-absorbing wall

Technical field

The utility model relates to a kind of body of wall, is specifically related to a kind of sound-absorbing wall that is used to abate the noise and pollutes.

Background technology

At present, often having on the next door of highway, railway line lives has the resident, but automobile, train etc. from highway, railway through out-of-date, often follow sizable noise, have a strong impact on resident's normal rest.But still there is not relative measures to solve this difficult problem now.

The utility model content

The utility model technical problem to be solved provides a kind of sound-absorbing wall that abates the noise and pollute.

The utility model solves the technical scheme that its technical problem adopted: sound-absorbing wall, comprise the acoustical cotton layer, and be arranged on positive front pressuring plate of acoustical cotton layer and the rear fender that is arranged on the acoustical cotton layer back side, front pressuring plate is provided with the passage that communicates with the acoustical cotton layer.

Further be, said front pressuring plate comprises many spaced apart Cross slats, and the interval between adjacent two Cross slats forms said passage.

Further be that said Cross slat is in tilted layout from the top down.

The beneficial effect of the utility model is: the sound-absorbing wall of the utility model is arranged on highway, railway both sides; When automobile, train from highway, railway through out-of-date; The noise that produces can get into the acoustical cotton layer through passage and effectively absorbed; Can reduce highway, railway noise on every side greatly, be beneficial near its resident's normal rest, the occasion that is adapted at various generation noise pollution is promoted the use of.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the lateral view of Fig. 1.

Be labeled as among the figure: acoustical cotton layer 1, Cross slat 2, rear fender 3, passage 4.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Like Fig. 1 and shown in Figure 2, the sound-absorbing wall of the utility model comprises acoustical cotton layer 1, is arranged on the front pressuring plate in acoustical cotton layer 1 front and the rear fender 3 that is arranged on acoustical cotton layer 1 back side, and front pressuring plate is provided with the passage 4 that communicates with acoustical cotton layer 1.During use, this sound-absorbing wall is arranged on the both sides of highway, railway etc., and makes acoustical cotton layer 1 positive front pressuring plate face highway, railway.Then through out-of-date, the noise of generation can pass through passage 4 entering acoustical cotton layers 1 and effectively absorbed, and can reduce highway, railway noise on every side greatly, is beneficial near its resident's normal rest from highway, railway for automobile, train.

In the above-described embodiment; The passage that is provided with on the front pressuring plate can be on integrally-built front pressuring plate, to offer through-hole form to realize; As preferred mode, said front pressuring plate comprises many spaced apart Cross slats 2, and the interval between adjacent two Cross slats 2 forms said passage 4.This form of structure is simple, is beneficial to and manufactures.

In order to reach best sound-absorbing effect, said Cross slat 2 is in tilted layout from the top down.Because automobile, the noise that train produces generally all are from the direction transmission of down past oblique upper, through Cross slat 2 is in tilted layout from the top down, can farthest noise absorption be fallen.
