Description

Soundproof Walls {NOISE BARRIER}

The present invention relates to a soundproof wall, and in particular, it is installed on a roadside to block vehicle noise to solve noise pollution in residential areas around the road. It relates to a soundproof wall that can be easily performed.

On the roadside, noise barriers are installed to block the noise generated by the vehicle from passing around the road.

In general, the soundproof wall is composed of a plurality of struts installed on the ground or concrete structure, and a soundproof panel installed between the struts. A plurality of sound insulation panels are laminated and manufactured at the height.

Soundproof panels are often provided with transparent soundproof panels for the purpose of securing sunshine and securing scenery and scenery for the driver.

Such a transparent soundproof panel has sound insulation characteristics that reflect the generated noise, but since only a simple reflection of the noise has no noise attenuation effect, the noise is transmitted to the surrounding area, resulting in complaints about noise pollution. Frequent

In addition, transparent soundproof panels are susceptible to contamination by dust or impurities, corrosion by calcium chloride or water, deformation and damage caused by vehicle collisions, and the like.

In particular, in the case of the sound insulation panel disposed at the bottom adjacent to the road, deformation or damage of the vehicle, such as corrosion due to a vehicle collision or pollutants, occurs relatively.

At this time, in order to replace or maintain the damaged sound insulation panel, maintenance work on the damaged sound insulation panel must be performed after removing all panels stacked on the upper side of the damaged sound insulation panel by a crane or the like. It is cumbersome, takes a long time, and causes a big economic loss.
