What are the main features and hidden functions of highway noise barriers?
2022-04-11
Highways are the most common places to use noise barriers, and their main features are as follows:
1. Flexible and convenient installation and use. Noise barriers are mostly designed in a modular way, making them very easy to disassemble and install.
2. Powerful function: The noise barriers on both sides of the highway have good sound absorption and sound insulation effects, and also have good durability, which can last for many years.
3. Good sound insulation effect. The average sound insulation of noise barriers is about 36dB, and the average sound absorption coefficient is high, maintaining around 0.83.
4. Strong durability. Noise barriers generally have water resistance, heat resistance, and UV resistance, and their performance will not be abnormal due to changes in rainwater temperature. Moreover, noise barriers mostly use aluminum alloy coils, galvanized coils, glass wool, and H-steel columns with galvanized surface treatment, and the anti-corrosion service life can be more than 15 years.
5. High strength. When designing the structure of noise barriers, 1.2mm galvanized steel plates are used, and grooves are pressed through an automatic production line to increase the strength, so that the noise barrier can withstand typhoons of level 10-12.
6. Waterproof, dustproof and durable. The louver design takes into account waterproofing and dust prevention, ensuring that the sound insulation screen is not affected by rain, and drainage measures are set up in the structure to prevent water accumulation inside the components.
These are the characteristics of sound insulation screens. In addition, highway sound insulation screens also have some hidden characteristics. Do you know what they are? Click to open the link
The Unknown Functions of Highway Noise Barriers
1. Preventing the spread of exhaust gas. There are often chemical plants on both sides of highways. After building noise barriers, the spread of exhaust gas can be effectively blocked.
2. Wind protection. Highway noise barriers come in many shapes: upright, top arc, top folding, etc., and generally have no problem resisting winds of level 5 to 6.
3. Beautiful appearance. Highway noise barriers are generally made of a combination of various materials, and the surface can be sprayed with various colors, making it easy to blend with the scenery on both sides of the highway.
