Damping jacket for railway rail and assembly method thereof

Abstract

The invention relates to the field of rail damping and denoising, in particular to a damping jacket for a railway rail and an assembly method thereof. The damping jacket for the railway rail comprises an expansion layer clung to the rail base and rail web of the railway rail, wherein a coating is formed outside the expansion layer, sealing layers are formed at two ends of the expansion layer and the coating, a closed space is formed by the expansion layer, the coating and the sealing layers, and the closed space is filled with liquid damping material. The assembly method comprises the steps as follows: (1) connecting the expansion layer, the coating and the sealing layer at one side together; (2) injecting the liquid damping material to a cavity; (3) arranging the other sealing layer at the opening position; (4) sleeving the damping jacket from one end of the railway rail; and (5) arranging sleepers at the bottom of the railway rail. According to the invention, the damping jacket filled with the damping material is coated on the rail, and the damping material has the damping and the denoising functions, so that the wheel rail noise generated by the rail vibration is effectively reduced.

Description

technical field [0001] The invention relates to the field of rail vibration reduction and noise reduction, in particular to a damping sheath for railway rails and an assembly method thereof. Background technique [0002] With the acceleration of my country's railway network construction and the continuous improvement of train operation speed, the problem of excessive noise in some sections along the line has aroused widespread concern from the whole society. At present, there are many shock and noise reduction measures, among which the more common method is to use sound barriers, but there are some significant disadvantages of sound barriers: due to noise diffraction, its effect is limited; the effect on high-rise buildings or deep valley environments is limited; Has a strong visual impact; high installation costs. There are other measures such as shock absorbers and dampers, but the effect is not ideal. The research shows that: when the train speed is 60-300km / h, the whee...
