Repairing method for settled ballastless track
The invention provides a repairing method for a settled ballastless track. The method comprises the following steps: chiseling off a sealing layer at the settlement position of the track so as to formsupporting spaces between the sealing layer and a supporting layer of the track; placing air cushions in the supporting spaces, and inflating the air cushions to lift a ballast bed foundation of thetrack to a preset height; placing base plates in the supporting spaces, and after the air cushions are deflated, withdrawing the air cushions; and backfilling the supporting spaces to recover the sealing layer, wherein the supporting spaces are evenly distributed in the longitudinal direction at intervals and are transversely and oppositely arranged on the two sides of the track, and the base plates are transversely and oppositely arranged in the supporting spaces.
本发明提供了一种用于沉降无砟轨道的修复方法，包括步骤：凿除轨道沉降处的封闭层，以在所述封闭层与轨道的支承层之间形成支撑空间；在所述支撑空间内安放气垫，并对所述气垫充气以抬升轨道的道床基础直至设定高度；在所述支撑空间内安放垫板，并对所述气垫放气后将所述气垫撤出；回填所述支撑空间，恢复所述封闭层；其中，所述支撑空间在纵向上均匀间隔开分布，且横向相对地设置在轨道的两侧，所述垫板横向相对地布置在所述支撑空间内。
