Abstract
The utility model relates to the technical field of highway construction equipment, especially a kind of speedway double-face sound-absorbing barrier, comprise the middle sound insulating panel perpendicular with express highway pavement, in the front and rear surfaces of described middle sound insulating panel, be symmetrically arranged with respectively barricade, the cross sectional shape of every described barricade is all " 7 " font, every barricade comprises panel decoration layer and is attached at the noise puigging on panel decoration layer medial surface, and middle sound insulating panel is provided with hyaline layer above the middle part of the part of barricade.This speedway double-face sound-absorbing barrier, reasonable in design, noise shielding is effective.
Description
Technical field
The utility model relates to the technical field of highway construction equipment, especially a kind of speedway double-face sound-absorbing barrier.
Background technology
Speedway can adapt to annual mean round the clock the minibus traffic volume be 25000 above, specialize in automobile shunting and run at high speed, and all control the highways of coming in and going out, the construction situation of speedway can reflect the traffic development degree of countries and regions and even the integral level of economic development.In order to improve expressway construction, relevant construction department has also carried out innovating significantly and studying to it, a lot of for the index of expressway construction, and noise shielding is exactly one of very important index wherein.
Yet, a little less than the shield effectiveness of existing highway noise shielding equipment, the resident living of speedway periphery has been produced to very large impact, a lot of people are seriously polluted because know speedway ambient noise, so most people is unwilling in the house-purchase of speedway periphery, the economic development of this speedway periphery that also just lagged behind.
Summary of the invention
The technical problems to be solved in the utility model is: the problem for the prior art solving in above-mentioned background technology exists, a kind of speedway double-face sound-absorbing barrier is provided, and reasonable in design, noise shielding is effective.
The utility model solves the technical scheme that its technical problem adopts: a kind of speedway double-face sound-absorbing barrier, comprise the middle sound insulating panel perpendicular with express highway pavement, in the front and rear surfaces of described middle sound insulating panel, be symmetrically arranged with respectively barricade, the cross sectional shape of every described barricade is all " 7 " font, every barricade comprises panel decoration layer and is attached at the noise puigging on panel decoration layer medial surface, and middle sound insulating panel is provided with hyaline layer above the middle part of the part of barricade.
Further limit, two barricades are fixedly connected with middle sound insulating panel by the mode of welding.
Further limit, two barricades are fixedly connected with middle sound insulating panel by trip bolt.
In order to guarantee the bulk strength of speedway double-face sound-absorbing barrier, therefore the thickness of middle sound insulating panel is more than or equal to the thickness of barricade.
The beneficial effects of the utility model are: speedway double-face sound-absorbing barrier of the present utility model, and reasonable in design, noise shielding is effective, and cost is low, can be widely used in expressway construction, has improved speedway periphery resident's quality of life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the elevation of Fig. 1.
In figure: 1, middle sound insulating panel, 2, barricade, 3, panel decoration layer, 4, noise puigging, 5, hyaline layer.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
A kind of speedway double-face sound-absorbing barrier as depicted in figs. 1 and 2, comprise the middle sound insulating panel 1 perpendicular with express highway pavement, in the front and rear surfaces of middle sound insulating panel 1, be symmetrically arranged with respectively barricade 2, the cross sectional shape of every barricade 2 is all " 7 " font, the corner of barricade 2 is connected by arc transition, and structural strength is higher.Every barricade 2 comprises panel decoration layer 3 and is attached at the noise puigging 4 on panel decoration layer 3 medial surface, middle sound insulating panel 1 is provided with hyaline layer 5 above the middle part of the part of barricade 2, hyaline layer 5 can be made by tempered glass, also can be made by transparent plastic.
Wherein, two barricades 2 can be fixedly connected with middle sound insulating panel 1 by the mode of welding.
Or two barricades 2 also can be fixedly connected with middle sound insulating panel 1 by trip bolt.
The thickness of middle sound insulating panel 1 is more than or equal to the thickness of barricade 2, guarantees the bulk strength of speedway double-face sound-absorbing barrier.
This speedway double-face sound-absorbing barrier, reasonable in design, noise shielding is effective, noise isolation effect is 2～4 times of common highway noises shielding device shield effectiveness, cost is low simultaneously, can be widely used in expressway construction, has improved speedway periphery resident's quality of life, promote more people to be willing to be intended to the house-purchase of speedway periphery, and then accelerated the economic development of speedway periphery.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on manual, must determine its technical scope according to claim scope.
