Acoustic Barrier mainly used for noise isolation and reduction of highways, expressways, elevated composite roads and other noise sources. It can divided into the reflection type sound barrier of pure sound insulation, and the compound sound barrier of sound absorption and sound insulation. The latter is a more effective sound insulation method.
It refers to the wall structures installed on the side of railways and highways to reduce the impact of traffic noise on nearby residents. Acoustic walls also called sound barriers.
An acoustic barrier is a device inserted between the source and the receiver so that the sound wave propagation has a significant additional attenuation,
thus reducing the impact of noise in a certain area where the receiver is located.
It is divided into traffic noise barrier, equipment noise attenuation noise barrier, industrial plant boundary noise barrier, highway and highway are used in many places of various types of sounds barriers.
The highway sound barriers mainly composed of steel structure column and sound absorption screen plate.
Above all,The column is the main stress component of the sound barriers,
which fixed on the embedded steel plate of the road anti-collision wall or track side by bolt or welding.
The sound insulation board is the main sounds insulation and absorption component,
Above all,which fixed in the H-shaped column slot through the high strength spring clip to form a sound barriers.
The design of sound barriers has taken into full consideration the problems of elevated expressway,
urban light rail, wind load of subway,
collision of traffic vehicles and all-weather open-air anti-corrosion.
It is beautiful appearance, exquisite production, convenient transportation, installation, low cost, long service life,
especially suitable for elevated highway and urban light rail, subway anti-noise use,is the most modern city sounds insulation and noise reduction facilities.
Road sound barriers generally made of aluminum, galvanized sheet and light cement. The hole type is generally louver hole type and micro – perforated long hole.
Plate thickness is generally between 0.8- 1.5mm.
The thickness of the finished product is generally 4-15cm.
Most widths are 50cm (can produced according to demand).
Length can processed according to the need for production.
The general bridge installed in the height of 2.5 meters, 3 meters of roadbed
