Road composite aluminum plate sound insulation barrier, used to reduce vehicle noise on both sides of the road, more and more vehicles on the road, resulting in a lot of noise, so in order not to affect the lives of people nearby A road composite aluminum panel sound barrier was installed.
Basic design principles for sound insulation barriers for highway composite aluminum panels:
(1) The horizontal position of the sound insulation barrier of the highway composite aluminum plate should be as close as possible to the sound source, which is beneficial to increase the shadow area of the sound insulation barrier, thereby improving the sound attenuation effect.
(2) The higher the sound barrier of the composite aluminum plate of the highway, the larger the shaded area and the greater the attenuation of the sound, which is obvious. However, the sound insulation barrier of the composite aluminum plate is too high, which may bring many problems such as structure, environment and cost, so the sound insulation barrier itself cannot be built too high.
When designing the composite aluminum plate sound insulation barrier, it should be adapted to the local conditions, using the topography and landform to improve the effective height of the composite aluminum plate sound insulation barrier, and obtain good results at a small cost.
(3) The form of the sound insulation barrier of the highway composite aluminum plate also has a great influence on the sound attenuation effect. If a provocation is protruded toward the sound source at the top of the composite aluminum plate sound barrier, it is equivalent to moving the entire composite aluminum plate sound barrier toward the sound source, which can effectively increase the depth and area of the shadow region. ,
However, when the sound insulation barrier of the highway composite aluminum plate is subjected to corrosive substances such as acid rain, it is necessary to take timely measures such as flushing with water. Reduce the impact of large impact objects, so as not to affect the appearance and service life of deformation!
