[0002] Noise barriers, also known as acoustic barriers, are specially designed acoustic barriers that stand between the noise source and the sound receiving point. They are mainly used for sound insulation and noise reduction on roads, expressways, elevated composite roads and other noise sources. They are divided into pure sound insulation reflective sound barriers and composite sound barriers that combine sound absorption and sound insulation. The latter is a more effective sound insulation method. It refers to a wall structure set up on the side of railways and highways to reduce the impact of traffic noise on nearby residents. It is divided into traffic sound insulation barriers, equipment noise attenuation sound insulation barriers, and industrial plant boundary sound insulation barriers. Roads and expressways are the places where various types of sound barriers are used most.

There are some safety hazards and the installation process is more cumbersome. For this reason, it is necessary to design a sound barrier wall structure that can install the sound barrier panels from bottom to top, which is easy to operate and reduces high-altitude operations.
