Ballastless track repairing method
The invention belongs to the technical field of track traffic maintenance, provides a ballastless track repairing method, and synchronously realizes lifting, falling and deviation correction of a ballastless track. A to-be-regulated range is equally divided into a plurality of units, operation grooves and foundation beds are excavated in batches in an alternate warehouse mode, supporting and backfilling are conducted in batches, after all the units are completed, track falling, lifting and deviation rectifying are conducted in a unified mode, and gaps below tracks are grouted and filled. During construction, adjacent units are discontinuously excavated, interference among the units is small, the suspension span of the track is reasonable, the deformation and cracking possibility is small, the track is in a reliable supporting state in the whole excavation and backfilling process, and the deformation possibility of the track is reduced. The method is not limited by a ballastless track structure and an operation space, is easy and convenient to operate, good in controllability, high in construction precision and efficiency and wide in applicability, does not affect railway operation and is safe, and various problems such as ballastless track settlement, upward arching and deviation caused by unqualified foundation bed filling materials or unqualified filling technologies can be rapidly and effectively solved.
本发明属于轨道交通维护技术领域，提供了一种无砟轨道修复方法，同步实现了无砟轨道的抬升、落道及纠偏。通过将待整治范围均分成多个单元，分批次跳仓开挖作业槽和基床，分批次进行支撑和回填，待全部单元完成后统一落道、抬升和纠偏，并对轨道下空隙进行灌浆填充。施工时相邻单元不连续开挖，单元间干扰小，轨道悬空跨度合理，变形开裂可能性小，开挖回填整个过程中轨道处于可靠支撑状态，减小了轨道变形的可能性。该方法不受无砟轨道结构以及作业空间限制，操作简便、可控性好，施工精度、效率高，适用性广，不影响铁路运营、安全，能够快速有效解决由于基床填充料不合格或者填充工艺不合格等原因引起的无砟轨道沉降、上拱和偏移等多种问题。
