Ballastless track bed structure part replacement method
The invention discloses a ballastless track bed structure part replacement method. The method comprises the following steps: (1) reinforcing a ballastless track bed; (2) drilling a wire saw operationhole in the damaged part of the ballastless track bed structural component; (2) cutting the damaged part of the ballastless track bed structural component into removable independent units by adoptinga wire saw; (3) removing the cut structural component; (4) temporarily limiting the ballastless track bed; (5) dismounting a temporary limit; (6) re-pouring the positions of the removed structural parts; (7) performing fine adjustment of the line. The method is simple, quick, safe and reliable, the geometrical state of the ballastless track is stable in the regulation process, the ballastless track supporting layer, the cement emulsified asphalt mortar layer, the CRTS III type track plate and the self-compacting concrete bonding structure can be replaced within skylight time, and normal operation of a train is not affected.
一种无砟道床结构部件更换方法，包括以下步骤：（1）无砟道床加固；（2）在无砟道床结构部件伤损部位钻取绳锯作业孔；（2）采用绳锯将无砟道床结构部件伤损部位切割成可移除的独立单元；（3）将切割后的结构部件移除；（4）无砟道床临时限位；（5）临时限位拆除；（6）已移除结构部件位置的重新浇筑；（7）线路精调。该方法简单快捷，安全可靠，整治过程中无砟轨道几何状态稳定，可在天窗时间内对无砟轨道支承层、水泥乳化沥青砂浆层及CRTSⅢ型轨道板与自密实混凝土粘结结构进行更换作业，不影响列车正常运营。
