Elevated bridge sound barriers are a current method for controlling bridge noise

　　Sound barriers are mainly used for noise reduction of noise sources such as expressways, highways, and elevated composite roads. They can be divided into purely sound-insulating reflective sound barriers and sound-absorbing and sound-insulating composite sound barriers. The latter has a better sound insulation effect and can be divided into elevated bridge sound barriers, equipment sound barriers, industrial plant boundary sound barriers, and highway sound barriers, etc.

　　Elevated bridge sound barriers are a current measure for controlling bridge noise. The planning of elevated bridge sound barriers needs to consider the surrounding environment and the noise level of the existing bridge. For bridges that have not yet been completed or registered, the noise of the scene can be directly measured, and then the height and required structure of the retaining wall can be calculated according to the theoretical formula. Before constructing the sound barrier, Confirm the background noise level of the existing bridge and calculate the height and required structure of the sound barrier according to the theoretical formula.

　　All components of the elevated bridge sound barrier are manufactured according to the architectural planning drawings during production and installed on site. They are beautiful in appearance, cleverly planned, low in cost, and have a long service life. They are especially suitable for noise reduction of bridges, elevated roads, expressways, urban light rail, and subways, and are an important measure for modern urban sound insulation and noise reduction.

　　What material are bridge sound barriers made of? Bridge sound barriers, also known as high-speed rail sound barriers, are noise-blocking facilities designed to reduce noise damage to people around bridges.

　　Bridge sound barriers, also known as high-speed rail sound barriers, are noise-blocking facilities designed to reduce noise damage to people around bridges. According to the application environment of the sound barrier, sound barriers can be divided into traffic sound barriers, equipment silencing sound barriers, and industrial plant boundary sound barriers.

　　We know that common sound barrier materials on the market mainly include metal sound barriers, concrete sound barriers, fiberglass reinforced plastic sound barriers, and PC sound barriers. Generally, metal sound barriers are relatively expensive and prone to rust; ordinary concrete is heavy and has low strength; fiberglass reinforced plastic sound barriers are expensive and not fireproof; PC sound barriers have high strength, light weight, strong weather resistance, and good toughness, and are the main material for bridge sound barriers. PC sound barriers are made of high-performance engineering plastics polycarbonate or polycarbonate ester. Their characteristics are: impact resistance and not easily broken; their strength is hundreds of times higher than that of tempered glass and acrylic plates. They are sturdy, safe, theft-proof, bulletproof, can be bent into arches, can be bent, have good machinability, strong plasticity, and can be bent into arches, semi-circles, and other styles according to the actual needs of the construction site. The material is light and easy to transport: the weight is only half that of glass, saving time and effort in transportation and installation, and making construction management convenient and easy. Excellent weather resistance and light transmission, long-term resistance to ultraviolet radiation, good light transmission effect, saving a lot of resources and costs.

　　Modified PC can be acid and alkali resistant, and UV is needed as a special anti-aging agent. In short, bridge sound barrier products have beautiful appearance, exquisite workmanship, convenient transportation and installation, low cost, and long service life. They are especially suitable for noise prevention of elevated roads, urban light rail, and subways, and are ideal sound insulation and noise reduction facilities for modern cities.

　　The above is a brief explanation of "Elevated bridge sound barriers are a current method for controlling bridge noise." I hope it can help everyone. Thank you for watching, and see you next time.
