Overhead double-track noise reduction system
The invention provides an elevated double-line track noise reduction system which is arranged on an elevated with two parallel tracks, each track comprises a base, a track bed, a sleeper and a steel rail, and the elevated double-line track noise reduction system is characterized by comprising a near-track sound barrier arranged on the outer side of the track in the extending direction of the steel rail; the track acoustic panel is laid on the ballast bed in the extending direction of the steel rail; the near-rail sound barrier comprises a sound barrier body, a mounting plate and a mounting frame, the mounting plate is fixedly mounted on the outer side of a rail through the mounting frame, the sound barrier body is arranged on the mounting plate and comprises a sound absorption layer, a sound transmission layer and a waterproof layer, and the sound absorption layer is arranged on the sound transmission layer. The waterproof layer is arranged on the surface, facing the mounting plate, of the sound absorption layer, the sound transmission layer wraps the sound absorption layer, and the edge of the sound transmission layer is fixedly connected to the surface, facing the mounting plate, of the waterproof layer.
本发明提供了一种高架双线轨道降噪系统，设置在具有两条并行轨道的高架上，轨道包括基底、道床、轨枕以及钢轨，其特征在于，包括：近轨声屏障，沿钢轨的延伸方向设置在轨道外侧；轨道吸音板，沿钢轨的延伸方向铺设在道床上；以及道床减振垫或道床隔振器中的任一种，设置在道床与基底之间，其中，近轨声屏障包括声屏障主体、安装板以及安装架，安装板通过安装架固定安装在轨道外侧，声屏障主体设置在安装板上，声屏障主体包括吸音层、透声层以及防水层，防水层设置在吸音层朝向安装板的表面上，透声层包裹在吸音层的外部，透声层的边缘固定连接在防水层朝向安装板的表面上。
