Ballastless track cutting structure, ballastless track cutting system and ballastless track cutting construction method for expansion-shrinkage deformation foundation
The invention discloses a ballastless track cutting structure, a ballastless track cutting system and a ballastless track cutting construction method for an expansion-shrinkage deformation foundation.The cutting structure comprises an enlarged foundation, deformation adjusters and a bearing device. The bearing device is arranged at the upper ends of the deformation adjusters, the deformation adjusters are fixedly connected with the top of the enlarged foundation, the deformation adjusters are arranged in the length direction of the rail at intervals, and the deformation adjusters are used fordiscovering deformation under the action of external force so as to allow the bearing device to move upwards or downwards. The cutting system adopts a cutting structure; the construction method is used for constructing a cutting system. The foundation is enlarged, so that large concentrated force transmitted by the deformation adjustors can be effectively diffused into the foundation; when the unfavorable deformation amount of the foundation exceeds the ballastless track requirement, the bearing device is driven by the deformation adjusters to move upwards or downwards to adjust the height ofthe foundation, so that the requirement for vertical deformation is met, the safety of a ballastless track railway is improved, and the ballastless track railway has good economical efficiency.
本发明公开了用于胀缩变形地基的无砟轨道路堑结构、系统及构造方法，路堑结构包括扩大基础、变形调节器和承载装置，承载装置设置在变形调节器上端，变形调节器与扩大基础顶部固定连接，变形调节器为至少两个，且沿轨道的长度方向呈间隔设置，变形调节器用于在外力作用下发现变形，以允许承载装置向上或向下运动。路堑系统采用了路堑结构，构造方法用于构造路堑系统，扩大基础使变形调节器传递的较大集中力能够有效的扩散到地基中，当地基的不利变形量超过无砟轨道要求时，通过变形调节器带动承载装置向上或向下运动来调整其高度，从而满足对竖向变形的要求，提高了无砟轨道铁路的安全性，并且具有良好的经济性。
