Description

Technical Field

[0001] The utility model relates to the technical field of sound barriers, in particular to a sound barrier for bypassing obstacles in front of a bridge section. Background Art

[0002] Sound barriers are primarily used for sound insulation and noise reduction on roads, expressways, elevated composite roads, and other noise sources. They are categorized as purely reflective sound barriers and composite sound barriers that combine sound absorption and insulation, the latter being a more effective method of sound insulation. They refer to wall-like structures installed alongside railways and highways to mitigate the impact of traffic noise on nearby residents. Soundproof walls are also known as sound barriers. A facility inserted between the sound source and the receiver creates significant additional attenuation in sound wave propagation, thereby reducing the impact of noise within a certain area surrounding the receiver. These facilities are categorized as traffic sound barriers, equipment noise attenuation sound barriers, and industrial plant boundary sound barriers. Highways and expressways are the most common locations for various types of sound barriers.

[0003] Currently, when sound barriers are installed on the roadside, they sometimes encounter obstacles such as lamp poles or trees. At this time, it is necessary to move forward to bypass the obstacles. However, since different obstacles are of different sizes, the sound barriers need to be cut and assembled, which can easily cause huge waste. Utility Model Content
