Product Details

High-speed railway sound barrier is a kind of sound barrier designed according to the current needs of high-speed railway.   

Features of high-speed railway sound barrier:   

Large sound insulation, high sound absorption coefficient, high strength, strong weather resistance, beautiful, easy to install and maintain, and can be sprayed with various colours according to user requirements   

The use of high-speed rail sound barrier:   

High-speed rail sound barrier is widely used in high-speed railway, intercity railway, urban light rail and other sound barrier projects.   

Technical parameters of high speed rail sound barrier:   

1、Sound insulation: 46.3dB(A);   

2、Sound absorption coefficient: 0.87;   

3、Wind pressure resistance performance: 3 seconds gust wind pressure (P=±3.00KPa) test Maximum deformation 29.5mm Maximum residual variance   

Common specifications of high-speed rail sound barrier:   

1960mm×500mm×100mm (length×width×thickness).   

Introduction to the performance of columns selected for high-speed rail sound barriers:   

4、Making process   

(1) Scientific selection of materials, according to the drawings of the H-beam steel under the material to ensure precision;   

(2) The undercutting of base plate is completed by CNC flame cutting with high precision;   

(3) The punching and welding of the bottom plate are done through strict process.   

5、Anti-corrosion treatment by hot dip galvanising and spraying for anti-corrosion treatment, the frame of the acoustic screen and acoustic bubbles are hot dip galvanised and then painted again to ensure excellent anti-corrosion performance.   

6、Mechanical properties Strong fatigue strength, weather resistance and deformation resistance.   

Note: High-speed rail sound barrier can be customised according to customer's drawing requirements, size and specification.
