Wheel track noise absorbing system and track system
The invention provides a wheel track noise sound absorption system which is arranged in a track system and used for absorbing and blocking wheel track noise, the track system comprises steel rails, a track bed and sleepers, the track bed is arranged on the ground, the sleepers are arranged on the track bed in a pairwise opposite mode, and the two parallel steel rails are installed on the track bed through the sleepers. Comprising a near-rail sound barrier which is arranged on the outer side of a steel rail and comprises a sound barrier main body, a mounting plate and a mounting frame; the at least one track sound absorption plate is laid on a track bed in the extending direction of the steel rail and comprises a sound absorption plate body, first protrusions and second protrusions, the sound absorption plate body is arranged on a mounting plate, the mounting plate is fixedly mounted on the outer side of the track through a mounting frame, the number of the first protrusions corresponding to each track sound absorption plate is two, and the number of the second protrusions corresponding to each track sound absorption plate is two. The two first protrusions are arranged at the two ends of the acoustic board body respectively, the first protrusions on the adjacent track acoustic boards are connected with each other, and the second protrusions are arranged on the side face of the acoustic board body.
本发明提供了一种轮轨噪音吸音系统，设置在轨道系统中，用于吸收和阻挡轮轨噪音，轨道系统包括钢轨、道床以及轨枕，道床设置在地面上，多个轨枕两两相对设置在道床上，两条相互平行的钢轨通过轨枕安装在道床上，其特征在于，包括：近轨声屏障，设置在钢轨外侧，包括声屏障主体、安装板以及安装架；以及至少一个轨道吸音板，沿钢轨的延伸方向铺设在道床上，包括吸音板主体、第一凸起以及第二凸起，其中，声屏障主体设置在安装板上，安装板通过安装架固定安装在轨道外侧，单个轨道吸音板对应的第一凸起的数量为两个，两个第一凸起分别设置在吸音板主体的两端，相邻的轨道吸音板上的第一凸起之间相互连接，第二凸起设置在吸音板主体侧面。
