Ballastless track and steel truss assembly type double-line roadbed structure thereof
The embodiment of the invention discloses a ballastless track and a steel truss assembly type double-line roadbed structure thereof. The steel truss assembly type double-line foundation structure comprises a top plate, a bottom plate, a steel truss and a support, wherein the steel truss is supported between the top plate and the bottom plate; and one part of the support is installed on a boss on the bottom side of the top plate and connected with the top end of the steel truss, and the other part of the support is installed on a boss on the top side of the bottom plate and connected with the bottom end of the steel truss. According to the roadbed structure, the foundation land area is reduced, the foundation treatment work amount is reduced, filler is omitted, and the construction cost isreduced; compared with a reinforced concrete member, the steel truss has obvious advantages in size and performance; the bosses increase the capacity of bearing the load transmitted by the steel truss; the cross section is inverted trapezoid, the width of the bottom plate is smaller than that of the top plate, so that the structure is more stable; the steel trusses are arranged in a triangular grid manner, so that the upper load is effectively transmitted, the structural weight is reduced, and the foundation bearing capacity requirement is reduced; all the components can be prefabricated, construction and quality control are facilitated, and operation and maintenance are convenient.
本发明实施例公开了一种无砟轨道及其钢桁架装配式双线路基结构，钢桁架装配式双线路基结构包括顶板、底板、钢桁架和支座，钢桁架支撑在顶板和底板之间，一部分支座安装于顶板底侧凸台上且与钢桁架顶端连接，另一部分支座安装于底板顶侧凸台上且与钢桁架底端连接。该路基结构降低了地基用地面积，减少了地基处理工程量，取消了填料，降低了施工成本；钢桁架在尺寸和性能上相比钢筋混凝土构件具有明显优势；凸台增加了承受钢桁架传递荷载的能力；横断面为倒梯形，底板宽度小于顶板宽度，使结构更稳固；钢桁架为三角形网格布置，有效传递上部荷载且减轻了结构重量，降低了地基承载力要求；各组件可预制装配，便于施工和质量控制，运营维护方便。
