[0002] Sound barriers are mainly used for sound insulation and noise reduction on highways, expressways, elevated composite roads and other noise sources, so as to reduce the impact of driving noise on nearby residents;

[0003] The existing sound barriers are generally directly fixed on the roadbed on both sides of the railway for use. During use, when the sound barrier needs to be dismantled for maintenance, all the fixings that fix the sound barrier need to be removed before the sound barrier can be removed, which makes the dismantling and maintenance of the sound barrier more cumbersome. Therefore, we have introduced a new non-metallic sound barrier for high-speed railways. Utility Model Content
