Factors causing potential safety hazards in sound barrier
Published:

The sound barrier is located in the outdoor environment along the railway. It is long-term affected by the temperature difference between day and night, ultraviolet rays and rainwater. The steel members of the sound barrier are easy to rust and corrode. The rubber strips may age and fail. Under the long-term action of fluctuating wind pressure, which is a frequent alternating load and vibration, the bolts may loosen and fail. The sound barrier unit plate is damaged and so on
The definition of sound barrier: it is to insert a facility between the sound source and the receiver, so that the sound wave propagation has a significant additional attenuation, and the sound barrier reduces the noise influence in a certain area where the receiver is located. Such a facility is called a sound barrier. barrier.
The sound barrier can be divided into the following categories according to the material classification: metal sound barrier (metal louvers, metal mesh holes), concrete sound barrier (lightweight concrete, high-strength concrete), PC sound barrier, glass fiber reinforced plastic sound barrier, etc., 2.7 meters wide The wide pc toughened plexiglass board has been officially produced, and the sound barrier has been successfully installed, greatly improving the visual and noise reduction effects.
So, what are the factors that cause safety hazards in the sound barrier?
1. The sound barrier is located in the outdoor environment along the railway line. It is affected by the temperature difference between day and night, ultraviolet rays, rain, etc. for a long time. The steel components of the sound barrier are easy to rust and corrode, and the rubber strips may age and fail. Under the long-term action of variable load and vibration, it may cause loosening and failure of bolts and connecting parts, and damage to the sound barrier unit plate.
2. Construction quality problems. The construction quality problems found so far include the clear distance of the sound barrier column and the length of the unit plate, the depth of the insertion of the two ends of the unit plate into the H-shaped steel column, the relevant elevation deviation does not meet the design requirements, and the sound barrier column is skewed.
