What are the advantages of high-speed sound barriers, and what is their environmental impact?

High-speed sound barrier combination design is flexible and free, can effectively control sound diffraction, and has a long service life. Its environmental impact includes humidity, wind volume, and temperature. The advantages and environmental impact of high-speed sound barriers are detailed below.

Advantages of high-speed sound barriers: They adopt a combination design, flexible and convenient for installation and disassembly. The overall shape of the high-speed sound barrier is straight, with an arc-shaped top plate, which can effectively control sound diffraction. It not only has good sound insulation and sound absorption effects but is also very durable and has a long service life. It should also be combined according to the principles of color and shape to create a harmonious effect with the surrounding environment. Energy-saving and environmentally friendly, because the raw materials used in production are green and pollution-free, and the production process generates high-temperature heat, which can effectively kill toxic gases. Short installation cycle, effectively saving labor costs. The underground part and the ground beam of the foundation are constructed using the method of digging holes and trenches. To minimize the disturbance to the roadbed soil, it is recommended to use manual excavation for pile foundations. In the construction of the foundation and floor beams, the advanced part should be poured with concrete of the same grade. When pouring the pile foundation concrete, an iron sleeve can be used to protect the soil wall to prevent soil particles from mixing into the concrete. For this high-speed highway sound barrier project, the location and elevation of the sound barrier are selected according to the intersection diagram of the relevant pile numbers. Therefore, before construction, the construction and installation unit should check and measure the location and elevation of the sound insulation foundation. The roadbed slope has an arched frame section, with a foundation spacing of 2m. Foundations are set in the middle of each arch, and ground beams are set in the reserved grooves of the frame protection. The pre-embedded parts of the high-speed highway sound barrier ground beam are handled and pre-embedded by the highway sound insulation barrier installation unit, and the concrete is poured through the installation unit to ensure installation quality. The anti-corrosion process of the highway sound barrier columns and fittings is hot-dip galvanizing.

Environmental impact of using sound barriers: 1. Sound barrier humidity: The water content of porous materials changes with changes in air humidity. Increased humidity of the roadbed sound barrier leads to increased pore water absorption, pore blockage, and reduced sound absorption coefficient, starting from high frequencies; it has the advantages of flame retardancy, corrosion resistance, low specific gravity, low thermal conductivity, strong chemical stability, low moisture absorption rate, and good hydrophobicity. It is considered to be a superior insulation, heat insulation, and sound absorption material with wide Applications. 2. Sound insulation air volume: The airflow in ventilation ducts and silencers simply blows away the porous sound-absorbing material, reducing the sound absorption effect, and stray substances can block the pipes and damage the fan blades.

3. Sound barrier temperature: Temperature causes changes in sound speed, wavelength, and air viscosity, affecting sound absorption. As the temperature rises, the sound absorption function shifts to the high-frequency direction, and the sound absorption function of the material weakens. As the temperature decreases, it shifts to the low-frequency direction. The above is an introduction to the advantages and environmental impact of high-speed sound barriers.
