Embedded track structure suitable for vibration and noise reduction transformation of existing subway
The invention discloses an embedded track structure suitable for vibration and noise reduction transformation of an existing subway line, the embedded track structure comprises an iron base plate, an elastic base plate, a lower foundation, a track plate, a steel rail, a filling assembly, a buffer assembly, a rubber pad, a locking assembly, a connecting assembly, a fastening assembly and a limiting assembly, and a base plate is arranged at the top of the lower foundation. According to the method, the embedded track is installed on the track bed or the track bearing table of the existing line through the anchor bolts by utilizing the bolt hole positions of the elastic strip fastener system of the existing line of the urban rail transit, the track bed and the track plate of the existing line do not need to be adjusted, and installation is simple and efficient. The high polymer material is used for continuously supporting and continuously locking the steel rail, vibration and noise reduction transformation is achieved, environmental vibration pollution caused by train running is reduced, the transverse vibration reduction effect of the steel rail is improved, transverse vibration can be better restrained in the curve section, good service performance is achieved, the service life of the rail structure is prolonged, and train running safety is guaranteed.
本发明公开了一种适用于既有地铁线路减振降噪改造的嵌入式轨道结构，包括铁垫板、弹性垫板、下部基础、轨道板、钢轨、填充组件、缓冲组件、橡胶垫、锁紧组件、衔接组件、紧固组件以及限位组件，所述下部基础的顶部设有底座板。本发明利用城市轨道交通既有线路的弹条扣件系统螺栓孔位，通过锚固螺栓将嵌入式轨道安装在既有线的道床或承轨台上，无需对既有线路道床和轨道板进行调整安装简单高效。利用高分子材料连续支承、连续锁固钢轨实现减振降噪改造减小列车行驶带来的环境振动污染，并且提高了钢轨横向减振效果在曲线段时能更好抑制横向振动，具有较好的服役性能，增加了轨道结构服役寿命，保证了列车运行安全。
