Abstract
Description
technical field
[0001] The invention belongs to the technical field of non-metallic sound barriers, and in particular relates to a combined non-metallic sound barrier unit plate. Background technique
[0002] The sound barrier is set on the wall structure next to the railway and road to reduce the impact of driving noise on nearby residents. By inserting a barrier facility between the noise source and the receiver, the sound wave propagation has a significant additional attenuation, thereby reducing the impact of noise in a certain area where the receiver is located.
[0003] In recent years, with the in-depth advancement of my country's transportation industry, especially the rapid development of high-speed railway construction, the noise problem along the line has become one of the serious pollution affecting people's quality of life. Therefore, the construction of sound barriers is the most effective way to solve the noise nuisance of high-speed rail.

Embodiment Construction
[0022] The structure and working principle of a combined non-metallic sound barrier unit panel provided by the present invention will be further described in detail below with reference to the accompanying drawings.
[0023] see figure 1 , is a schematic cross-sectional view of a combined non-metallic sound barrier unit panel provided by the present invention. The structure constituting the combined non-metallic sound barrier unit panel includes a panel 1, a back panel 2 and a sound-absorbing material 3 placed between them; wherein, the panel 1 is recessed to form a shell with a cavity 4, and the sound-absorbing material 3 Placed in the box cavity 4, the panel 1 and the back panel 2 are connected 5 by bolts, the panel 1 is poured from air-filled concrete, and the panel 1 is provided with evenly distributed sound-absorbing holes 11 .
[0024] Its working principle is: the panel 1 of the combined non-metallic sound barrier unit panel is formed by pouring air bubble concrete, sp...
