Product Description
Specifications Railway Noise Barrier
Material:PC Sheet,metal sheet
Type; Shutter,microvoid
post: ''H'' steel
ISO9001:2000
Railway Noise Barrier Definition: Sound waved during the process of transmission, meets the sound barrier occurs when the reflection,transmission and diffraction three kind of phenomenon. Classify: 1. Sound barrier according to the material classification and can be divided into the following categories: metal sound barrier(metal shutter, metal screen hole), concrete sound barrier (lightweight concrete, high strength concrete), PC sound barrier, FRP acoustic barrier, etc. 2.According to the different uses and can be classified into such categories: railway noise barriers , highway sound barrier, urban landscape sound barrier, residential area drop noise barrier,etc. Structure : Sound barrier is mainly composed of steel structure column and suction acoustic screen plate of two parts, the pillar of the noise barrier is the main stress components, i t through the bolt or welding fixed in road anti knock at the door or track side of the embedded steel plate; Suction noise barrier is the main acoustic acoustic components, it through the high strength spring clamp should be fixed to the H type column slot, form the sound barrier. Sound barrier height in 1m between 5m, covering effective regional average noise reduction for 10---15db(125hz--40000hz ,a third octave),the highest 20db. Generally speaking, the higher the sound barrier ,or from the sound barrier more far,the noise reduction result is better.
