[0002] Rail transit (railway transportation) is a land transportation mode in which locomotives pull train vehicles on two parallel rails. Controlling rail transit noise and vibration is an important issue for improving passenger comfort and environmental protection. A large number of studies have shown that track structure is an important factor causing vibration and noise. In order to control vibration and noise, rubber pads are usually set under the rails in the prior art.

The fixing method is troublesome and difficult to remove. Under the long-term rolling of the tracks, the rubber pads often need to be replaced, making the ordinary installation method inconvenient for workers to disassemble and replace.
