Method for renovating rail cant of ballastless track
The invention relates to a ballastless track bottom slope renovation method which comprises the following steps: a bad track bottom slope renovation preparation stage: collecting bad track bottom slope renovation parameters, and designing a renovation angle required by a bad track bottom slope of each track bearing table according to theoretical calculation and field test; an undesirable rail cant trimming implementation stage: on the basis of not influencing other parts of the original rail structure, trimming the angle of the rail cant by adopting a rail cant trimming device according to the trimming angle of the undesirable rail cant, so that the rail bearing table descends for a certain distance on the original foundation; the maximum grinding angle of the rail cant trimming device is 3 degrees, and the poor rail cant trimming range is-1: 40 to 1: 15; and a recovery stage after finishing of the bad rail cant: recovering the rail bearing table after finishing to meet the operation requirements. The method has the advantages that a construction method for polishing and finishing the bad rail cant of the ballastless track with the blocking shoulder by adopting the profile profiling of the rail bearing table is adopted, so that the purpose of eliminating the bad influence of the bad rail cant on the shaking of a high-speed rail crane, the abnormity of a steel rail light band and the like is achieved.
本申请涉及一种无砟轨道轨底坡整治方法，不良轨底坡修整准备阶段：采集不良轨底坡修整参数，根据理论计算和现场测试，设计各承轨台不良轨底坡所需的修整角度；不良轨底坡修整实施阶段：在不影响原轨道结构其他部位的基础上，根据不良轨底坡修整角度，采用轨底坡修整装置对轨底坡的角度进行修整，使承轨台在原基础上下降一定距离；所述轨底坡修整装置的最大打磨角度为3°，不良轨底坡整治范围为‑1:40至1:15；不良轨底坡修整后恢复阶段：将修整完整后的承轨台恢复至满足运营要求。本发明的优点是：采用承轨台廓形仿形打磨修整带挡肩无砟轨道轨底坡不良的工法，以达到消除不良轨底坡对高铁行车晃车、钢轨光带异常等不良影响的目的。
