The selection principles of sound insulation walls for highways:
The general principles for selecting materials for highway soundproofing walls are good noise reduction performance, safe and reliable structure, economical material price, low installation cost, durability, long service life, coordinated landscape, and elegant appearance. The specific instructions are as follows:
(1) High sound insulation: The average sound insulation should not be less than 35dB;
(2) High sound absorption coefficient: The average sound absorption coefficient should not be less than 0.84;
(3) Weather resistance and durability: The product should have water resistance, heat resistance, UV resistance, and will not be degraded or have abnormal quality due to changes in rainwater temperature. The products are made of aluminum alloy coiled plate, galvanized coiled plate, Glass wool, and the galvanized outer surface of H steel column has a anti-corrosion life of more than 15 years.
(4) Aesthetics: Multiple colors and shapes can be selected for combination, coordinating with the surrounding environment to form a beautiful scenery.
(5) Economy: prefabricated construction can improve work efficiency, shorten construction time, and save construction costs and labor costs.
(6) Convenient: Parallel installation with other products, easy to maintain, and easy to update.
Sound barriers are mainly used for sound insulation and noise reduction of highways, highways, elevated composite roads, and other noise sources. Divided into pure sound insulation reflective sound barriers,
A composite sound barrier that combines sound absorption and insulation, the latter being a more effective sound insulation method. Refers to reducing the impact of driving noise on nearby residents
A wall like structure set on the side of railways and highways. Acoustic walls are also known as sound barriers. Insert a facility between the sound source and receiver to make the sound

Precautions for construction of sound insulation walls on highways:
1) The position of the highway soundproof wall in the project is inevitably changed during the construction process. Therefore, before construction, the construction and installation units must verify and measure the position and elevation of the foundation of the highway soundproof wall column, and make necessary corrections.
2) When setting out during construction, the designated elevation of the civil engineering project must be used as the control point.
3) The construction unit of H-shaped steel column embedded parts shall cooperate with the construction at a spacing of 2500 mm.
4) The columns and installation parts of the highway soundproof wall should undergo anti-corrosion treatment.
5) After the H-shaped steel column is accurately positioned, the vertical error shall not be greater than 2mm/m after adjusting its horizontal and vertical straightness.
6) EVA sponge rubber strips are used to seal the two ends of the highway soundproof wall screen and the steel columns, and EVA sponge rubber pads are used to seal the gap between the highway soundproof wall and the foundation.
7) The use of snap springs must ensure that the soundproof wall materials on highways are installed firmly and must not cause secondary noise due to looseness.
Loading of noise barrier
Features:
High sound insulation: The average sound insulation is 37dB.
Number of sound absorption systems: high sound absorption coefficient 0.95
Weathering durability: The product has water resistance, heat resistance, UV resistance, and will not decrease performance or quality abnormalities due to changes in rainwater temperature.
Aesthetics: Multiple colors and shapes can be selected for combination, coordinating with the surrounding environment to form a beautiful scenery.
Economy: prefabricated construction can improve work efficiency, shorten construction time, and save construction costs.
Convenient: Parallel installation with other products, easy to maintain, and easy to update.
Safety: Both ends of the sound-absorbing board can be connected and fixed with steel wire ropes to prevent secondary damage and damage to personnel and property.
Lightweight: The large arc sound barrier product has the characteristic of light weight, with a mass of less than 25 kilograms per square meter, which can reduce the load-bearing capacity of elevated light rail and elevated roads, and can reduce structural costs.
Fire prevention: ultra-fine Glass wool is used. Because of its high melting point and non combustible, it fully meets the requirements of environmental protection and fire prevention specifications, and its fire protection rating reaches Grade A.
