Embedded track structure of high-speed railway
An embedded track structure of a high-speed railway comprises a base and a track plate on the base, and is characterized in that the track plate is formed by prefabricating reinforced concrete, and aheight adjusting base plate, an elastic base plate and a steel rail are arranged in two track bearing grooves in the track plate from bottom to top; track adjusting grooves are longitudinally formed in the track bearing grooves at equal intervals; track adjusting pieces on the two sides of the steel rail in the track adjusting grooves are fixed to the bottoms of the track adjusting grooves throughanchor bolts; damping blocks are embedded between the front hammers of the track adjusting pieces and the rail webs of the steel rails; polyurethane filling bodies are filled between the track bearing grooves outside the track adjusting grooves and the steel rails; the bottom surface of the track plate is connected with a cast-in-place self-compacting mortar layer; and protrusions on the top faceof the self-compacting mortar layer are matched with grooves in the bottom face of the track plate, and an isolation layer is arranged between the bottom face of the self-compacting mortar layer andthe prefabricated base. The track structure can greatly reduce environmental noise, and reduce corrugation of steel rails and maintenance of anchor bolts, and track maintenance is convenient and low in cost; and batch and mechanical production and automatic laying of the tracks can be realized, so that the high-speed railway lines are convenient and quick to lay.
一种高速铁路嵌入式轨道结构,包括基座和基座上方的轨道板,其特征在于:轨道板为钢筋混凝土预制而成,轨道板上的两条承轨槽内从下至上设有调高垫板、弹性垫板和钢轨;承轨槽纵向等间距设有调轨槽;调轨槽内钢轨两侧的调轨件通过锚固螺栓固定在调轨槽底部;且调轨件的前锤与钢轨的轨腰间嵌有阻尼块;调轨槽以外的承轨槽与钢轨间用聚氨酯填充体填满;轨道板的底面与现浇的自密实砂浆层连接;自密实砂浆层顶面的凸起与轨道板底面的凹槽配合,底面与预制的基座间设有隔离层。该轨道能大幅降低环境噪声,减少钢轨的波磨和锚固螺栓的维护,轨道养护方便、成本低;还能实现轨道的批量化、机械化生产和自动化铺设,使高速铁路线路铺设方便、快捷。
