Trackside noise reduction system of rail transit roadbed
The invention discloses a trackside noise reduction system of a rail transit roadbed, which comprises first noise reduction devices symmetrically arranged on the outer sides of rails and a second noise reduction device arranged between two rails, the first noise reduction devices are arranged between the outer sides of the rails and cable troughs, and the distance between the first noise reduction devices and the center line of the rails is 180-330cm; the first noise reduction device is composed of an upper section, a middle section and a lower section embedded in a roadbed, the section of the upper section in the vertical direction is of an arc-shaped structure, a step-shaped structure, a rectangular structure or a bevel-shaped structure, and the sections of the middle section and the lower section in the vertical direction are rectangular; the distance between the second noise reduction device and the center line of the rails on the two sides is consistent, the second noise reduction device is composed of an upper portion located on the roadbed and a lower portion embedded in the roadbed, and the sections of the two portions in the vertical direction are rectangular. The noise reduction system is close to a sound source, the noise reduction effect is improved, the defect that the noise reduction effect is insufficient when a vehicle runs at the far end is overcome, and the noise reduction system is low in construction cost, extremely small in maintenance workload and long in service life.
本发明公开了一种轨道交通路基的轨旁降噪系统，包括对称设置在轨道外侧的第1降噪装置和设置在两条轨道之间的第2降噪装置，第1降噪装置设置在轨道外侧与电缆槽之间，距离轨道中心线180～330cm；第1降噪装置由上段、中段以及埋入路基的下段组成，所述上段在竖直方向的截面呈弧形结构、阶梯型结构、矩形结构或折角形结构，所述中段和下段在竖直方向的截面为矩形；第2降噪装置与两侧轨道中心线的距离一致，由位于路基上的上部和埋入路基的下部组成且这两部分在竖直方向的截面均为矩形。该降噪系统距离声源较近，提高了降噪效果，弥补了车辆远端运行时降噪效果不足的弊端，其施工成本低、维修工作量极小，使用寿命长。
