Problems solved by technology

Bridges are built to connect roads on both sides of mountains, lakes, and seas. The top and bottom of bridges are very open, but bridges are often located above rivers, and it is precisely in these places that strong winds are prone to occur, and the air movement on bridges is relatively large. The flat area is more active and the airflow speed is faster, so it is easy for the sound insulation screen to be blown down by the side wind on the bridge deck during use, causing traffic accidents

Abstract

The invention discloses a bridge sound insulation barrier, which belongs to the technical field of sound insulation devices, and comprises a wall and several wind-resistant and sound-insulating units arrayed on the middle and upper part of the wall. jack, the jack runs through the inside and outside sides of the wall; the wind-resistant and sound-insulating unit includes a rectangular shell, and the shell is sequentially connected with an air inlet cavity and a swirl cavity along the inside to the outside of the wall and the air outlet chamber, the natural wind enters the swirl chamber from the air inlet chamber and is guided and rotated by the inner wall of the swirl chamber before being discharged from the air outlet chamber. Wind effect, sound insulation and wind resistance are better.

Description

Technical field [0001] The present invention belongs to the technical field of the sound insulation device, and specifically, a bridge sound-insulating barrier. Background technique [0002] Sound Insulation Screen is an emoticon facility. It in order to block the sound source and the recipient, insert a facility between the sound source and the recipient, there is a significant additional attenuation between the acoustic wave propagation, thereby attenuating the noise effect in a certain area where the recipient is located. Sound sound barriers are mainly used for traffic noise governance such as roads, railways, high-speed rails to sound insulation. Of course, there are no soundproof screens on both sides of the existing bridges. The construction bridge is to connect the roads on both sides of the mountain, lake, and sea. Above the bridge is very empty, but the bridge is often above the river, and it is easy to have a wind, the air movement on the bridge is better. The flat are...
