Method for repairing vertical reflection crack of ballastless track filling layer
The invention discloses a method for repairing a vertical reflection crack of a ballastless track filling layer, which comprises the following steps of: under the condition of track plate coverage, removing a filling layer part which is corresponding to a joint cutting position and has generated a vertical reflection crack; cleaning equipment is connected with the hollow pipeline to clean the cavity and the kerfs; flexible filling materials are injected into the kerfs to form flexible filling of the kerfs; the edge of the cavity is sealed, and a pouring hole and an exhaust hole are reserved; a repairing material is poured into a cavity in the sealing edge until the exhaust hole overflows slurry so as to ensure full pouring; and after the repairing material reaches the preset strength, the sealing edge is removed, and repairing of the filling layer is completed. By means of the technical scheme, the good waterproof effect of the kerf is still achieved under the condition that the environment temperature changes, secondary diseases caused when water permeates into the lower portion of the track are avoided, the durability of the filling layer is remarkably improved, and continuous degradation of the filling layer at the kerf position is avoided.
本发明公开了一种无砟轨道充填层的竖向反射裂缝修复方法，包括：在轨道板覆盖情况下，清除切缝位置对应的已产生竖向反射裂缝的充填层部分；采用清理设备连接中空管道对空腔及切缝进行清理；向切缝注入柔性填充材料形成对切缝的柔性填充；对空腔的边缘进行封边，并留设灌注孔和排气孔；向封边内的空腔灌注修复材料，灌注至排气孔溢浆以确保灌注饱满；在修复材料达到预设强度后，拆除封边，完成对充填层的修复。通过本发明的技术方案，实现了切缝在环境温度变化的情况下仍具有良好的防水效果，避免了水渗入轨道下部引发的次生病害，显著提升了充填层的耐久性能，避免了切缝位置处充填层的持续劣化。
