Product Details
Construction site of Zhengzhou Metro South Fourth Ring Project undertaken by Jiangsu Guoqiang Galvanising Industry Co.
High-speed rail sound barrier application environment, sound barriers are divided into traffic noise barriers, equipment noise attenuation noise barriers, industrial plant noise barriers. Outdoor sound barriers are usually constructed of bricks or concrete, while indoor sound barriers are constructed of steel plates, wooden boards PMMA/POLYCARBONATE SHEET plastic wrenches, gypsum boards and foam aluminium. Generally speaking, the higher the sound barrier, or the farther away from the sound barrier, the better the noise reduction effect.
At the beginning of the planning of sound barrier, it has been more fully considered the city light rail, elevated high-speed road, traffic vehicle collision safety, the wind load of the underground and all-weather open-air anticorrosion questions. High-speed rail sound barrier is mainly composed of steel structure column and sound-absorbing and sound-insulating screen plate, the column is fixed on the roadway collision wall or track side of the pre-embedded steel plate through bolts or welding, which is the primary force components of the sound barrier; sound-absorbing and sound-insulating plate is fixed in the groove of the H-type column through the high-strength taut spring card, which constitutes the sound barrier, and it is the primary acoustic sound insulation and acoustic components. The height of high-speed railway sound barrier is between 1m and 5m, covering the useful area with uniform noise reduction of 10-15dB(A) (125Hz～40000Hz, 1/3 octave), up to 20dB(A).
High-speed rail sound barrier has beautiful appearance, exquisite manufacture, convenient delivery and installation, low cost, long service life, especially suitable for noise prevention of elevated high-speed road and urban light rail, underground, and it is the most ideal sound insulation and noise reduction equipment in modern cities.
Metro sound barrier is mainly composed of steel structure column and sound-absorbing screen plate two parts, column is the primary force components of the metro sound barrier, it is fixed by bolts or welding in the roadway anti-collision wall or track side of the embedded steel plate; sound-absorbing plate is the primary acoustic sound-absorbing components, it is through the high-strength taut spring card will be fixed in the H-type column groove, constituting the metro sound barrier.
The planning of the underground sound barrier has fully considered the wind load of the elevated high-speed road, urban light rail, underground, the safety of the traffic vehicle collision and the all-weather open-air anti-corrosion problems. It has beautiful appearance, exquisite manufacture, convenient delivery and installation, low cost, long service life, and is especially suitable for the noise prevention of elevated high-speed road and urban light rail, underground, and is the most ideal sound insulation and noise reduction equipment for modern cities. Underground sound barrier, height in 1m a 5m, cover the useful area of uniform noise reduction of 10 ~ 15dB (A) (125Hz ~ 40000Hz, 1/3 octave), up to 20dB (A). Generally speaking, the higher the underground sound barrier, or the farther away from the sound barrier, the better the noise reduction effect.
Metro sound barriers have exquisite manufacturing technology, beautiful appearance, convenient delivery and installation, low project cost, and long service life, making them the most ideal sound insulation equipment for urbanisation in modern society. The uniform sound insulation amount of underground sound barrier can reach 37db, and the uniform sound absorption coefficient is more than 0.9. According to the calculation of relevant materials, the higher the underground sound barrier is, or the farther away from the underground sound barrier is, the better the sound insulation effect is.
