Description

A new lightweight fully enclosed sound barrier for urban viaducts

technical field

The invention relates to the technical field of sound barriers, more specifically, the invention relates to a new type of lightweight fully enclosed sound barrier for urban viaducts.

Background technique

According to the structural form, the sound barrier can be divided into vertical type and fully enclosed type. The vertical type of sound barrier can also be derived into L-type, Y-type, T-type, semi-circular and so on according to the different top forms. The sound wave from the noise source will change its path when encountering the sound barrier. Part of it will pass through the sound barrier to reach the sound receiving point, part of it will be reflected by the screen body, and the other part will bypass the top of the sound barrier to reach the sound receiving point. That is, there are three paths of transmission, reflection and diffraction. The vertical sound barrier will form a sound shadow area behind its screen body. For the sound recipients in the sound shadow area, the vertical sound barrier can achieve the purpose of effective protection. The sound barrier of different top forms is equivalent to increasing the height of the screen body, which will increase the sound insertion loss of the sound barrier to the sound shadow area to a certain extent, increasing by about 1-2.5dB(A).

Among them, the fully enclosed sound barrier seals all the roads and vehicles in the screen body, and completely seals the noise source, so that the sound waves are reflected in the screen body multiple times to better energy consumption and attenuation. At the same time, it also prevents diffracted sound waves. The existing sound barriers have the following disadvantages. One is that when the sound barrier is impacted, the vibration generated by the impact cannot be eliminated. The other is that there is no special base, or the base is not stable enough and is easily damaged. The third is that the sound barrier is often set up relatively large and covers a large area, but it has no additional functions other than sound insulation and noise reduction.
