What should we pay attention to when installing the sound barrier? The noise barrier of railway covers the useful area from 1 m to 5M in height, with an average noise reduction of 10-15 dB (a) (125-40000 Hz, 1/3 octave), and noise reduction of 20 dB (a).

Generally speaking, the higher the railway sound barrier is, or the farther away from it, the better the noise reduction effect.

(1) Construction period requirements and construction organization

(2) Structure and height of the project

(3) The structure selection of the frame should be made to ensure the structure safety and reliability, and the cost of the structure should be reasonable.

(4) The sound barrier can meet the expected safety and durability under the rule condition and the regular service life.

(5) When selecting materials, make every effort to make them universal and reusable for maintenance and repair.

(6) When selecting structure, it is necessary to ensure clear stress, put structural measures in place, convenient lifting and inspection.

(7) Combined with the above points, the scaffold construction must also meet the requirements of the code for safety inspection of construction and construction, and the relevant standards of provincial civilized specification for chemical industry.

The railway sound barrier is mainly composed of steel structure column and panel. The sound barrier column of expressway is a component of sound barrier. Railway sound barrier is a road fixed to embedded steel plate close to wall or track by bolts or welding. The soundproof panel is a sound insulation component. And fixed in h-pillar groove by high strength spring clamp. A good barrier.

The sound barrier planning of railway fully considers the factors such as expressway, urban light rail sound barrier, subway wind load, traffic vehicle collision safety, all-weather corrosion prevention and other factors. The sound barrier is beautiful in appearance, excellent in manufacture, convenient in transportation, convenient in installation, low in cost and long in service life, especially for elevated highway and urban light rail.
