Embodiment

[0033] An embodiment of the double-sided sound-absorbing and noise-reducing device for a railway track of the present invention, the sound-absorbing and noise-reducing device is mainly used in the field of sound-absorbing and noise-reducing railway tracks, especially subway rails, and is installed on the suspended section of rail 2 between adjacent sleepers 1 to reduce noise and improve ride comfort. The structure of the sound-absorbing and noise-reducing device is as follows: figure 1 and figure 2 shown by figure 1 and figure 2 It can be seen that it mainly includes two double-sided sound-absorbing panels 3, and the two double-sided sound-absorbing panels 3 are respectively pasted on both sides of the rail 2 in the suspended section through the adhesive layer 4, and absorb and reduce the noise on both sides of the rail 2 at the same time. The double-sided sound-absorbing panel 3 includes a sound-absorbing upper panel 31 and a sound-absorbing lower panel 32 . Among them,...

Abstract

The invention discloses a double-faced sound absorption and noise reduction device of a railway track, and an installation method thereof. The railway track comprises a plurality of sleepers (1) and steel rails (2) erected on the plurality of sleepers (1), the sound absorption and noise reduction device is installed on the steel rail (2) on a suspended segment between adjacent sleepers (1), the sound absorption and noise reduction device comprises two double-faced sound absorption boards (3), the two double-faced sound absorption boards (3) are respectively adhered on two sides of the steel rail (2) on the suspended segment through adhesion layers (4), each double-faced sound absorption board (3) comprises an upper sound absorption panel (31) and a lower sound absorption panel (32), the upper sound absorption panel (31) is arranged toward the upper side of the railway track, and the lower sound absorption panel (32) is arranged toward the bottom of the railway track. The sound absorption and noise reduction device has the advantages of easy implementation, low cost and good sound absorption and good noise reduction effect.

Description

technical field [0001] The invention relates to the technical field of sound absorption and noise reduction for railway tracks, in particular to a double-sided sound absorption and noise reduction device for railway tracks and an installation method thereof. Background technique [0002] The railway track (especially the subway) will generate noise due to track irregularities and other reasons during operation. The noise reaches a certain decibel, which will affect the ride comfort in the tunnel, and affect the daily life of the surrounding residents along the viaduct. [0003] At present, scholars at home and abroad have carried out a lot of research on railway vibration and noise reduction technology, and produced some vibration and noise reduction technologies and products, such as rail grinding technology, vibration-damping track plates, vibration-damping fasteners, sound-absorbing track plates, noise reduction patch etc. However, the above-mentioned technologies and pr...
