Intelligent frame plate type ballastless track structure
The invention belongs to the field of intelligent construction of high-speed railways, and particularly relates to an intelligent frame plate type ballastless track structure which comprises a reinforced concrete base, a cement asphalt mortar layer, a prefabricated frame type intelligent track plate and the like. FRP-OFBG intelligent composite bars, a fiber grating sensor, a core mold and the like are embedded in the track plate, and the track plate is formed through concrete pouring. A pair of hollow frame structures are arranged on the track plate in the length direction at intervals, the frame structures are communicated through a hollow channel formed by a core mold, and a light composite cover plate capable of being powered by solar energy is installed for sealing. Compared with a traditional CRTSI type slab ballastless track, the track is convenient for maintenance personnel to inspect, effectively slows down track slab warping caused by temperature stress, supplies power to field test monitoring equipment, and introduces an intelligent real-time monitoring system to perform long-term service performance monitoring. The ballastless track plate is compatible with the current high-speed railway CRTSI type plate ballastless track plate, and is suitable for industrial production.
本发明属于高速铁路智能建造领域，具体涉及一种智能框架板式无砟轨道结构，包括钢筋混凝土底座、水泥沥青砂浆层以及预制框架式智能轨道板等。轨道板内嵌有FRP‑OFBG智能复合筋、光纤光栅传感器和芯模等，通过混凝土浇筑成型。轨道板沿长度方向间隔设置一对中空的框架结构，框架结构之间通过芯模形成空心通道相连通，并安装可太阳能供电的轻型复合盖板以封闭。相较于传统CRTSⅠ型板式无砟轨道，本发明方便维护人员巡检，有效减缓温度应力引起的轨道板翘曲，还为现场试验监测设备供电，同时引入智能化实时监测系统可进行长期服役性能监测。本发明与目前高速铁路CRTSⅠ型板式无砟轨道板兼容，适合工业化生产。
