Wing-run sound barrier - sound barrier tender engineering manufacturer

Anping Yong Yun Hardware Co., Ltd. mainly for road and rail tender works of professional metal sound barrier manufacturer, has a professional R & D team and installation team! The company has the ability of independent research and development, can be produced according to customers' actual needs! Mainly used for road traffic noise source and sides of the road by an acoustic barrier between the protected area. Since the noise generated by road traffic to people's lives, work and study caused inconvenience and damage, so the highway noise barrier by setting down the noise reduction is an important road noise reduction measures. Highway Sound Barrier (road noise walls) consists of two parts of steel columns and suction insulation panel composed of columns is the main force member road noise walls, which is fixed by bolts or welding anti-wall road or rail side of the pre- buried steel; suction insulation board is the primary acoustic absorption member, it is through high-strength spring clips to secure the H-type column groove formed sound barrier. Highway Sound Barrier Applications: General acoustics noise control in a variety of high-speed railways, highways, viaducts, rail transportation, power stations, hospitals, schools, construction sites and other industrial enterprises noise reduction products. Highway sound barriers, height 5m 1m a room, cover the effective regional average noise reduction of 10 ~ 15dB (A), up to 20dB (A). In general, the higher road noise walls, or farther away from the highway noise walls, noise, the better. Quality control of road noise walls: 1, highway sound barrier Excavation: Press the Measure Stakeout excavation, excavation of soil poured directly specified place outside the roadbed. 2, mechanical testing and template preparation highway sound barrier: the day before the opening of the mixer mix, vibrator, generators seizure cases, no-load air operation, cleanup templates, smear release agent; template uses steel supports, 3, material inspection highway sound barrier: the frequency can be detected according to specifications of the indicators meet the requirements of the material can be used, and the moisture content of the aggregate daily inspection, adjustment construction mix ratio.
