Background
With the rapid development of economic construction in China, urban rail transit and urban railways are rising with a rapid trend. Urban rail transit and urban railways often pass through sensitive areas such as residential areas, hospitals and schools, and cause noise pollution to the surrounding environment, so that the lives of people along the line are influenced. The proportion of the overhead lines of urban railways and urban rail transit is large, so that how to reduce the noise pollution of the overhead bridge section is always a general concern.
At present, noise pollution along a railway mainly comprises noise generated by wheel-rail friction and motor driving noise, and a traditional sound barrier is additionally arranged in a sensitive area to reduce the influence on the surrounding environment. And the large application of the traditional sound barrier inevitably consumes a large amount of manpower, material resources and financial resources.
Therefore, in view of the above-mentioned drawbacks, the designer of the present invention develops a vertical type short sound barrier for overhead lines by combining the experience and achievement of the related industry for many years through careful research and design to overcome the above-mentioned drawbacks.

In order to achieve the above object, the utility model discloses a short sound barrier of vertical type nearly rail for overhead line, include steel stand, sound barrier backplate, inhale sound cotton and rubber strip, its characterized in that:
the steel stand sets up on a base and supports the sound barrier backplate, the sound barrier backplate contains roof, intermediate lamella, bottom plate and connecting plate and a plurality of cavitys that form, inhale in the cotton cavity of fixing to the sound barrier backplate of sound, the rubber strip is fixed to the both ends of roof, intermediate lamella and the bottom plate of sound barrier backplate.
Wherein: the steel upright is H-shaped to provide effective support.
Wherein: the sound barrier back plate is made of glass fiber reinforced plastic composite materials.
Wherein: inhale the sound cotton and be a plurality of and correspond the sticky cavity of fixing to the sound barrier backplate.
Wherein: the rubber strips are multiple and are glued and fixed to the two ends of the top plate, the middle plate and the bottom plate of the sound barrier back plate.
Wherein: the vertical type near-rail low sound barrier for the overhead line is arranged on bridge faces or retaining walls on two sides of the rail.
Wherein: the horizontal direction of the vertical type near-rail low-height sound barrier for the overhead line is far away from the equipment safety limit within 620cm, and the vertical direction is far away from the steel rail surface 7 by less than 1.2 m.
As can be seen from the above, the vertical type short sound barrier for overhead lines of the present invention has the following effects:
1. the steel rail safety limiting device can be conveniently and quickly arranged on bridge surfaces or retaining walls on two sides of a rail, the horizontal direction of the steel rail safety limiting device is far away from the device safety limiting limit within 20cm, and the vertical direction of the steel rail safety limiting device is far away from the height of a steel rail surface by less than 1.2 m.
2. The height is low, the distance is closer, and on the premise of ensuring the sound absorption and insulation effect, the height of the sound barrier is reduced, so that steel and a sound barrier back plate are saved, the construction condition is improved, and the bridge stress load and the landscape effect are facilitated.
The details of the present invention can be obtained from the following description and the attached drawings.
