Description

Technical Field

[0001] The present invention relates to the technical field of sound barriers, and in particular to a sound insulation barrier for an assembled bridge. Background Art

[0002] A sound barrier is a sound insulation facility. In order to block the direct sound between the sound source and the receiver, a facility is inserted between the sound source and the receiver, so that the sound wave propagation has a significant additional attenuation, thereby reducing the noise impact in a certain area where the receiver is located. The sound barrier is mainly used for traffic noise control such as roads, railways, and high-speed railways to play a role in sound insulation and noise reduction. Of course, some existing bridges are also equipped with sound barriers on both sides.

[0003] A Chinese patent (CN219195623U) discloses an elevated bridge with a sound insulation barrier, comprising sound insulation panels and fixing piles fixedly connected to the tops of guardrails on both sides of the elevated bridge, the fixing piles being fixedly connected between two adjacent sound insulation panels, sound absorbing windows being evenly distributed on the front side of the sound insulation panels, a latch assembly being provided on the rear side of the sound insulation panels, a latch seat being correspondingly provided on the rear side of the fixing piles, and an end of the latch assembly being inserted into the latch seat.

[0004] However, there are some disadvantages in the above-mentioned related technologies.
