Urban track traffic brings people great convenience, and its noise pollution also seriously affects people's normal life. Setting track traffic concrete noise barrier is a very useful way to deal with noise pollution.

The sound barrier is mainly composed of steel structure column and sound absorption and isolation panel, and the column is the primary stress component of the sound barrier.

It is fixed on the road anti-collision wall or the embedded steel plate beside the track by bolts or welding; The sound absorption and insulation board is the primary sound insulation and absorption component, which is fixed in the H-shaped column slot through the high-strength tension spring clip to form a sound barrier. The planning of Cangzhou Jiuhe sound barrier has fully considered the problems of elevated high-speed road, urban light rail, subway wind load, traffic vehicle collision safety and all-weather open air anti-corrosion.

It has beautiful appearance, exquisite manufacture, convenient transportation and installation, low cost and long service life. It is especially suitable for the anti noise application of elevated high-speed roads, urban light rail and subway. It is a very ideal sound insulation and noise reduction equipment in modern cities. Urban track traffic noise and general railway noise have both similarities and unique characteristics in acoustic characteristics.

For example, the urban track traffic is generally 2-8-car EMU, the choice of all or part of the EMU, generally running in the tunnel and viaduct. It is not as long as the railway noise experience time (a pass), but the driving frequency is higher than that of the railway, generally every 2min ~ 5min. It is different from the road traffic noise, road traffic is often composed of many connected point sound source line sound source.
