Is a bridge sound barrier useful for high-rise residential buildings?

　　Many residential users are concerned about this issue. After the installation of the bridge sound barrier, it is also helpful for high-rise residential buildings. After the sound is blocked by the sound barrier, it will drift from the top, which will greatly reduce the noise. However, the specific noise reduction level depends on the height of the sound barrier and the distance between the residents and the sound barrier! It is recommended to use sound hole or louver type sound barriers.

　　Measurements of the noise reduction effect of bridge sound barriers on high-rise residential buildings were carried out over a wide range in the vertical direction. By monitoring the sound pressure level of different floors of high-rise buildings before and after the construction of sound barriers, it was found that the sound barriers had a significant noise reduction effect on low-rise buildings. The floor with the best noise reduction effect is the 6th floor. Outside the sound shadow area, the sound barrier still has a noise reduction effect on noise-sensitive buildings, and the noise reduction effect decreases with the increase of building height. The vehicle distribution density of different lanes has different effects on the noise reduction effect of the sound barrier.

　　Bridge sound barriers have a significant noise reduction effect. Now, the method used in traffic is to install sound barriers to reduce noise. The decibel reduction is large, and it can meet the noise reduction standards, providing a quiet environment for people's life, work and study. Moreover, sound barriers not only consider noise reduction, but also consider the landscape effect. In order not to damage the surrounding environment, there are many types of sound barriers to choose from. In addition, the current transparent sound barriers have a wide range of applications and can blend with the surrounding environment, with wide Applications.

　　What issues should be paid attention to during the operation period of bridge sound barriers?

　　After the installation of the bridge sound barrier, it does not mean that it is over. The sound barrier needs regular inspection and maintenance to check whether the sound insulation performance meets the standards and whether the integrity is good.

　　During the operation period, the maintenance of the sound barrier should be included in the daily maintenance scope, and the connection rate of the sound barrier unit panels and bolts should be checked regularly.

　　Are there any gaps on the surface of the sound barrier; Is there any looseness between the sound barrier unit panels and between the sound barrier unit panels and the H-shaped steel columns; If the above problems are found, they should be dealt with promptly.

　　The following components should be regularly repaired and replaced every six months to one year: The bolts connecting the H-shaped steel columns should be tightened regularly to ensure that the H-shaped steel columns are reliably connected to the foundation;

　　H-shaped steel columns, bolts and triangle brackets should be regularly derusted and anti-corrosion treated to meet the strength requirements of each component; If the sound barrier unit panel is damaged, and the rubber parts are nearing the end of their service life, they should be replaced in time;

　　When the main structure exceeds its design service life, the operating unit should promptly report to the superior department and, together with a unit with certain design qualifications, conduct on-site inspection and design review to ensure structural safety. If necessary, the design can be replaced again according to the actual on-site conditions.

　　These are the issues that should be paid attention to during the operation of bridge sound barriers. Because sound barriers have high requirements for firmness and sound insulation performance, various maintenance departments need to conduct inspections.
