Near-rail sound absorption and insulation device
The invention relates to a near-rail sound absorption and insulation device and belongs to the technical field of urban rail transit. The device is composed of a connecting piece and noise reduction bodies, wherein the connecting piece is fixedly connected with a sleeper through a bolt, the noise reduction bodies are fixedly connected with the connecting piece, the noise reduction bodies are L-shaped rubber integral products, two end surfaces of each noise reduction body are closed and are concave-convex primary and secondary rabbets respectively, and every two adjacent noise reduction bodiesare in butt joint through concave-convex primary and secondary rabbets, vertical surface transverse waves and vertical surface vertical waves of the noise reduction body are arranged at intervals, planes of the noise reduction bodies are downward slopes, and plane vertical waves and plane transverse waves of the noise reduction bodies are arranged at intervals. The device is easy to manufacture, safe, convenient to install and maintain, small in occupied space, free of extra foundation, low in height and close to a noise source, the good sound absorption effect is achieved, construction conditions are improved, and the view of passengers is enlarged.
一种近轨吸隔声装置，属于城市轨道交通技术领域，它由连接件、降噪体组成；连接件通过螺栓与轨枕固定连接，降噪体与连接件连接固定；所述降噪体为呈L型橡胶整体制品，降噪体两个端面封闭且分别为凹凸子母企口，相邻两个降噪体通过凹凸子母企口对接；降噪体的立面横波和立面竖波间隔布置；降噪体平面为斜坡向下，降噪体的平面竖波和平面横波间隔布置。本发明制作简单，安全，安装方便，检修便捷，占用空间小，不用额外做基础，高度虽降低，但距离噪声源近，同样达到很好的吸音效果，改善施工条件，扩大旅客的视野。
