Vibration reduction barrier structure for subway tunnel and construction method
The invention relates to the technical field of subway vibration reduction and noise reduction, in particular to a vibration reduction barrier structure for a subway tunnel and a construction method. A vibration reduction barrier structure for a subway tunnel comprises a barrier, a vibration reduction device and a rail supporting mechanism. The barrier is arranged in a tunnel and connected with the bottom of the inner wall of the tunnel through a plurality of vibration reduction devices. The rail supporting mechanism is arranged at the bottom in the barrier, and the barrier is provided with at least two sets of elastic hydraulic devices used for being connected with the rail supporting mechanism to achieve vibration reduction. The elastic hydraulic devices are symmetrically arranged on the two horizontal sides of the rail supporting mechanism. In some special areas, such as hospitals, scientific research institutions and other places where precise instruments and equipment are stored, the influence caused by train passing is stronger. The vibration reduction barrier structure can actively conduct and weaken vibration waves generated by operation of the subway train, cut off the propagation path of noise and reduce the influence of vibration noise on the outside.
本发明涉及地铁减振降噪技术领域，更具体地，涉及一种用于地铁隧道的减振屏障结构及施工方法。一种用于地铁隧道的减振屏障结构，包括屏障、减振装置和轨道支撑机构；所述屏障设于隧道内，并通过多个减振装置与隧道内壁底部连接；所述轨道支撑机构设于所述屏障中的底部，所述屏障设有至少两组用于连接轨道支撑机构实现减振的弹性液压装置；各组弹性液压装置对称设于所述轨道支撑机构的水平两侧。在某些特殊区域，如医院与科研院校等存放精密仪器设备的场所列车经过造成的影响更加强烈。安装该减振屏障结构可以主动传导并减弱地铁列车运行产生的振动波，切断噪音的传播途径，减少振动噪音对外部的影响。
