Abstract
The utility model provides a protective screen structure gives sound insulation, ARC support frame unit including the lateral part support frame of a plurality of bilateral symmetries is different with a plurality of tops radian height is formed, its characterized in that, and the left side portion support frame of every unit comprises A subtotal B part two parts, and right side portion support frame comprises C subtotal D part, and the main part support frame is formed to left side portion support frame and right side portion support frame. The top supporting frame puts up G by top supporting frame F and top supporting to be constituteed, and top supporting puts up and the lateral part support frame links to each other, and top supporting frame G is higher than the tie point that top supporting put up F and lateral part support frame with lateral part support frame tie point. The utility model discloses noise transmission can be effectively blocked, because lateral part and top form a plurality of inclined planes, can the noise be offset by multiple refraction simultaneously to keep apart closed transmission and multiple refraction and offset the noise, reach the purpose of good improvement road noise.
Description
Technical field
The invention belongs to field of Environment Protection, be mainly used in traffic noise treatment, be specifically related to a kind of totally-enclosed noise barrier.
Background technology
Roadside has many environment sensitive spots such as residential quarter, school, office building, causes very large noise pollution because vehicle travels the noise produced to environment sensitive spot along the line.
Summary of the invention
In order to solve above-mentioned problem of noise pollution, the present invention proposes the effective totally-enclosed noise barrier of a kind of sound insulation and noise reducing.
A kind of noise barrier structure, include the curved support frame unit composition that multiple monosymmetric side supports frame is different with multiple tops radian height, it is characterized in that, the left side bracing frame of each unit is made up of part A and part B two parts, right side bracing frame is made up of C part and D part, left side bracing frame and right side bracing frame composition main bracing frame.Top supporting frame is made up of top supporting frame F and top supporting frame G, top supporting frame is connected with side supports frame, top supporting frame G and side supports frame tie point are higher than the tie point of top supporting frame F and side supports frame, top sound insulating panel is arranged between top supporting frame F and top supporting frame G, between top supporting frame, form inclined-plane, form the noise barrier ceiling face closed.Sidepiece sound insulating panel is arranged between part A and part B, and part A and part B form two inclined-planes, and side supports frame lower end is connected by column bolt with described ground base;
Described totally-enclosed noise barrier, when vehicle travels the noise transmission produced, form noise in described totally-enclosed sound barrier inside and close isolated area, effective block noise route of transmission, simultaneously because multiple inclined-plane is formed on sidepiece and top, can repeatedly reflect counteracting noise, thus isolation is closed route of transmission and is repeatedly reflected counteracting noise, reaches the object of good improvement road noise.

Detailed description of the invention
Certain railway, width 11 meters, length 300 meters, road both sides are all school and living area.Due to school and living area distance railway very near, noise pollution is serious.Polluting for thoroughly administering road noise, just totally-enclosed noise barrier will be installed on road.
Totally-enclosed noise barrier overall height 7.5 meters.With reference to Fig. 1, this project is made up of the bracing frame of 75 left sides, right side symmetry and top supporting frame, top supporting frame is connected with side supports frame, top supporting frame G and side supports frame tie point are higher than the tie point of top supporting frame F and side supports frame, top sound insulating panel is arranged between top supporting frame F and top supporting frame G, between top supporting frame, form inclined-plane, form the noise barrier ceiling face closed.Sidepiece sound insulating panel is arranged between Left-side support frame part A and part B, between C part and D part, part A and part B form two inclined-planes, and C part and D part form two inclined-planes.Left-side support frame, Right side support frame are connected with ground base by column bolt.
In totally-enclosed noise barrier, height 5 meters of in both sides are at interval of 50 meters, and the contact net that both sides devise needed for 120 electric trains altogether connects shelf, convenient-laying contact net circuit.
When the noise transmission that train driving produces, form noise in described totally-enclosed sound barrier inside and close isolated area, effective block noise route of transmission, simultaneously because sidepiece and top are made up of multiple inclined-plane, repeatedly can offset noise reflection, thus isolation is closed route of transmission and is repeatedly offset noise, reaches the object of good improvement road noise.Totally-enclosed noise barrier excellent noise reduction effect, cost is low, attractive appearance, efficiently solves the pollution problem of railroad noise.
