Description

Technical Field

[0001] The utility model relates to the technical field of sound barriers, in particular to a waterproof sound barrier. Background Art

[0002] The sound barrier for overpasses is a facility used to reduce the impact of road traffic noise on the surrounding environment. With the acceleration of urbanization, the noise pollution problem caused by road traffic is becoming increasingly serious, especially on overpasses or highways near residential areas. In order to improve the quality of life of residents and reduce the negative impact of noise, installing sound barriers has become a common solution.

[0003] In the prior art, multiple sound-absorbing panels are fixed in parallel and spanned between two mounting frames. Since there is a gap between the opposite ends of the sound-absorbing panels and the mounting frames, rainwater will drip onto the ground from the gap after falling on the sound-absorbing panels, forming multiple water curtains in the sound barrier for the viaduct. In addition, in the cold winter, rainwater can easily form icicles in the gap at the connection between the sound-absorbing panels and the mounting frames, posing a safety risk.
