Enclosure type noise barrier
Enclosure noise barrier can achieve better sound insulation effect, and the noise reduction effect is obviously improved than unilateral or bilateral sound barrier. It can basically solve the noise impact of residential areas from urban expressway and viaduct road.
Enclosure noise barrier effectively blocked the re-propagation of noise, but also because of its height and special materials to effectively ensure the safety of our driving environment. This design and installation not only meets the needs of noise insulation and noise reduction, but also adds a double guarantee to traffic safety.
Enclosure noise barrier
1. Large amount of sound insulation: the average sound insulation should be no less than 35dB;
2. High sound absorption coefficient: the average sound absorption coefficient should be not less than 0.84;
3. The sound barrier durability of the community sound barrier: the product should have water resistance, heat resistance and resistance. Ultraviolet rays do not cause deterioration in performance or quality due to changes in rain temperature. The product adopts aluminum alloy coil plate, galvanized coil plate, glass wool, and H steel column surface for galvanizing. The corrosion protection period is more than 15 years.
4. Aesthetic: You can choose a variety of colors and shapes to combine and coordinate with the surrounding environment to form a beautiful landscape.
5. Economy: Assembly-type construction, improve work efficiency, shorten construction time, and save construction and labor costs.
6. Convenient: It is installed in parallel with other products, easy to maintain and easy to update.
7. overall curved sound barrier. Lightweight: The sound barrier series products have the characteristics of self-weight and light weight, which can reduce the load-bearing load of overhead light rail and elevated road, and reduce the structural cost.
