Noise reduction and shock absorption device for track in tunnel
The invention relates to the technical field of track damping, in particular to a noise reduction and damping device for a track in a tunnel, which comprises a noise reduction mechanism for forming a water curtain to intercept noise in the tunnel, the noise reduction mechanism comprises a reservoir which is mounted on the ground and is internally provided with a water pump, and a first vertical pipe and a second vertical pipe are vertically arranged on the reservoir; according to the noise reduction and shock absorption device for the track in the tunnel, a water curtain is formed through flowing-out water, noise generated when a train runs in the tunnel is absorbed, noise reflection is reduced, and the situation that in the closed environment in the tunnel, noise reflection and gathering cause noise amplification, and the noise reduction effect is affected is avoided. In addition, when the train runs on the rail, pressure can be continuously applied to the interior of the metal cylinder, the pressure of the interior of the metal cylinder on the protruding block is changed, then the fixing block and the rail are connected stably and pre-tightened, and vibration of the rail caused by high-speed running of the train is greatly reduced.
本发明涉及轨道减震技术领域，具体为一种隧道内轨道的降噪减震装置，包括形成水幕对隧道内噪声拦截的降噪机构，所述降噪机构包括安装在地面且内部设置有抽水泵的蓄水池，所述蓄水池上竖立有第一竖管与第二竖管，本发明的目的在于提供一种隧道内轨道的降噪减震装置，通过流出的水形成水幕，对列车行驶在隧道时产生的噪音进行吸音，减少噪声反射，避免在隧道内的封闭环境下，噪音反射和聚集，导致噪声会被放大，进而对车内乘客造成耳鸣甚至带来危险，另外列车在轨道上行驶时，可以通过不断对金属筒内部施压，改变其内部对凸块的压力，进而对固定块与轨道的连接起到稳定以及预紧作用，大大减少轨道因列车高速行驶而产生的震动。
