Light roadbed structure of high-speed railway
The invention discloses a light roadbed structure of a high-speed railway. The light roadbed structure comprises a box type roadbed, a cantilever structure and a rigid pile foundation, wherein the boxtype roadbed comprises a top plate which is integrally formed and horizontally arranged, two side wall plates which are vertically arranged and a bottom plate which is horizontally arranged, all thecomponents are fixedly connected to form a closed box-shaped structure, and the section of the closed box-shaped structure is in a closed rectangular shape; and the two ends of the top plate extend outwards to form outer cantilevers and extend towards the center line of the roadbed to form inner cantilevers, and damping rubber materials are filled between the adjacent inner cantilevers to seal andstop water. A track plate and a track supporting system are arranged on the top plate, an anti-collision wall, a cable trough and a contact net stand column base are sequentially arranged on the outer cantilevers, and a protective fence is arranged at the ends of the outer cantilevers. Vertical drainage ducts are formed in the positions, close to the outer side wall plates, of the top plate of the box type roadbed; a rigid pile foundation is arranged at the bottom of the box type roadbed. According to the method, the sloping range of the slope of the high-speed railway embankment is greatly reduced, the foundation reinforcement work amount is reduced, and the use amount of rigid piles and the filling amount of railway roadbed filler are reduced.
本发明公开了一种高速铁路轻型路基结构，包括箱型路基、悬臂结构和刚性桩基础；箱形路基包括一体成形水平设置的顶板、两个竖向设置的侧壁板以及水平设置的底板，各构件间固定连接形成的闭箱形结构，截面呈封闭矩形；顶板两端分别向外侧延伸形成外悬臂，向路基中心线延伸形成内悬臂，相邻内悬臂之间填充阻尼橡胶材料，封闭止水；轨道板及轨道支撑系统置于顶板上，外悬臂之上依次设置防撞墙、电缆槽、接触网立柱底座，外悬臂端部设置防护栅栏；箱形路基的顶板临近外侧侧壁板的位置设置竖向排水孔道；刚性桩基础设置在箱型路基的底部。本发明大幅减小了高铁路堤边坡放坡范围，降低了地基加固工程量，减少了刚性桩用量和铁路路基填料填方量。
