The invention discloses a noise reduction device suitable for a subway track, and belongs to the technical field of underground traffic facilities. The noise reduction devices are uniformly arranged at intervals in the longitudinal direction of a track; each noise reduction device comprises a track groove formed between the two subway tracks, a partition plate is arranged in the middle of each track groove and divides the track groove into an upper cavity and a lower cavity, the upper portion of a silencing plate is located in the upper cavity, the lower portion of the noise reduction plate is located in the lower cavity, the lower end of the silencing plate is fixedly connected to a sliding block, a sliding track is arranged at the bottom of the track groove in the transverse direction, the sliding block is in sliding fit with the sliding track, the lower cavity is filled with damping liquid, and vibration of the silencing plate can be damped under the action of the damping liquid. The device can reduce noise in the running process of the subway, reduce noise pollution and bring a more comfortable riding environment to passengers.
本发明公开了一种适用于地铁轨道的降噪装置，属于地下交通设施技术领域，所述降噪装置沿着轨道的纵向均匀间隔布置；每一降噪装置包括形成在两地铁轨道之间的轨道槽，所述轨道槽的中部设置有一隔板，所述隔板将所述轨道槽分隔呈上腔室和下腔室，消音板的上部位于所述上腔室内，所述消音板的下部位于所述下腔室内，所述消音板的下端固定连接至一滑块，所述轨道槽的底部沿横向设置有一滑轨，所述滑块与所述滑轨滑动配合，所述下腔室内填充有阻尼液，所述消音板震动能够通过所述阻尼液的作用进行消音。本发明装置可以降低地铁在运行过程中的噪音，减少噪音污染，给乘客带来更舒适的乘车环境。
