Vibration and noise reduction device for subway tunnel
The invention belongs to the technical field of subway tunnels, and particularly relates to a subway tunnel vibration and noise reduction device which comprises a shield shell, and a supporting seat is fixedly mounted in the shield shell; a flat plate is fixedly mounted on the surface of the supporting seat; the flat plate is arranged on the lower surface of the subway track; a supporting clamping block is fixedly mounted on the lower surface of the flat plate; during working, when a subway train passes through the surface of a subway track, vibration and part of noise generated by train running can be transmitted to the surfaces of the flat plate and the anti-vibration cushion layer, rubber concrete and polymer damping materials in the anti-vibration cushion layer can block part of vibration, pressure borne by the anti-vibration cushion layer and the flat plate is reduced, and the anti-vibration effect is improved. Through the supporting clamping blocks with the hollow interiors, noise generated when the train passes through can be subjected to energy conversion in the cavities, and therefore noise propagation is relieved; the influence of vibration waves and noise generated when the subway passes through a residential area on people is avoided, and normal living of people is facilitated.
本发明属于地铁隧道技术领域，具体的说是一种地铁隧道减振降噪装置，包括盾构壳体，所述盾构壳体的内部固定安装有支撑座；所述支撑座的表面固定安装有平板；所述平板设置与地铁轨道的下表面；所述平板的下表面固定安装有支撑夹块；工作时，在地铁列车通过地铁轨道的表面时，列车运行产生的振动以及部分噪音会传递到平板以及减振垫层的表面，减振垫层内部的橡胶混凝土以及聚合物阻尼材料会对部分振动进行阻断，减轻减振垫层和平板所受到的压力，且通过内部为空心状的支撑夹块，可以将列车经过时产生的噪音在空腔内进行能量转化，从而减轻噪音的传播；避免地铁在经过居民区时产生的振动波以及噪音对人们的影响，有利于人们的正常起居。
