Problems solved by technology

[0002] At present, the plug-in metal sound barrier is the main sound barrier used along the railway in my country. However, long-term chemical medium or rain erosion will cause the metal sound barrier to gradually corrode and rust, which will damage the internal structure of the sound barrier and affect the working life of the sound barrier.
Sound barriers require frequent maintenance and repairs, greatly increasing operating costs and worker workload
At present, the thickness of common concrete or metal sound barriers is about 0.1m, and the weight per unit length can reach about 200-300kg / m. The installation of this kind of sound barriers is very inconvenient and must be equipped with heavy machinery to complete.
