Description

Technical Field

[0001] The utility model relates to the technical field of sound barriers, in particular to an anti-falling sound barrier. Background Art

[0002] Sound barriers are wall-like structures installed on the sides of railways and highways to reduce the impact of traffic noise on nearby residents. They are currently widely used in various regions across the country and can be divided into ground sections and bridge sections according to their installation location.

[0003] Sound barriers are divided into vertical sound barriers, semi-enclosed sound barriers and fully enclosed sound barriers. Whether it is a semi-enclosed sound barrier, a fully enclosed sound barrier or a vertical sound barrier, it includes a vertical part, which is fixed on both sides of the road. The sound barrier wall is formed by inserting the sound-absorbing panels into the adjacent steel sections. When this part of the sound barrier is hit by a vehicle, the sound-absorbing panels are easy to fall out of the steel sections, or more seriously, the sound-absorbing panels will scatter. If it is on an elevated road, these detached or scattered sound-absorbing panels are likely to cause secondary damage to pedestrians under the road.

[0004] Therefore, the applicant proposes an anti-falling sound barrier to solve the above problems. Utility Model Content
