High-speed railway noise reduction structure
The invention discloses a high-speed railway noise reduction structure which is arranged on a bridge protection wall, extends along the outer side of a high-speed railway track and is located outside a railway building limit, and the side, close to the track, of the noise reduction structure is 180-240 cm away from the center line of the track and 40-125 cm away from the lower portion of a wheel track and a train. The section, in the vertical direction, of the noise reduction structure is of a rectangular structure or a stepped structure or a bevel structure or an arc-shaped structure. In a section with noise exceeding 3dB (A), trackside noise reduction structures with different heights and forms are adopted to replace a sound barrier, so that the construction cost can be greatly reduced, the maintenance workload is extremely small, and the service life is long.
本发明专利公开了一种高速铁路降噪结构，所述降噪结构设置在桥梁防护墙上、沿高速铁路轨道外侧延伸并位于铁路建筑限界外，所述降噪结构临近轨道一侧距离轨道中心线180～240cm，距离轮轨和列车下部40～125cm；所述降噪结构在竖直方向的截面为矩形结构、阶梯形结构、折角形结构或弧形结构。在噪声超标3dB(A)以内的区段，采用不同高度和形式的轨旁降噪结构替代声屏障，能大大降低施工成本，并且维修工作量极小，使用寿命长。
