采用混凝土轨枕的曲线轨道由于扣件磨损、钢轨侧面磨耗、以及超高不适当使上下股受力不均匀等原因,引起钢轨外挤、内侧扣钣偏离、轨距扩大等病害,需要改道。曲线半径越小,改道越频繁。传统的改道办法是,更换 Curved track using concrete sleepers due to wear fasteners, rail wear side, as well as the upper and lower strands are not super-high enough to force uneven and other reasons, resulting in crowded outside the rail, the inner buckle buckle deviation, gauge widening and other diseases, the need for diversion. The smaller the radius of the curve, the more frequent the diversion. The traditional diversion is to change
