Construction method for rapidly repairing monolithic ballast bed settlement in skylight period
The invention discloses a construction method for rapidly repairing monolithic ballast bed settlement in a skylight period. The repairing construction method is used for being carried out in a skylight period and comprises the following steps that height adjusting fasteners are adopted for recovering line positions, original long sleepers and surrounding ballast bed concrete are chiseled away, newshort sleepers are laid, reinforcing steel bars are implanted, formworks are erected, and pouring is carried out through polymer cement mortar. The sleeper is repaired and constructed in the skylightperiod; according to the construction method, through the polymer cement mortar, pouring and maintaining are performed to form a new ballast bed structure; rapid recovery of monolithic ballast bed settlement is realized; the construction method is small in on-site engineering quantity; the polymer cement mortar can quickly harden a ballast bed; and the ballast bed repairing construction period isshortened, an influence on operation is greatly reduced, a gap between a rail bottom and a ballast bed surface is increased through the height adjusting fasteners, a space requirement for installinga steel rail emergency device during work rush repair can be met, emergency disposal time is shortened, and the influence on train operation and passenger travel is reduced.
本发明公开了一种天窗期内完成整体道床沉降快速修复施工方法，该修复施工方法用于在天窗期内进行，包括以下步骤：采用调高扣件恢复线位、凿除原长轨枕及周围道床混凝土、铺设新短轨枕、钢筋植入、支立模板以及通过聚合物水泥砂浆进行浇筑。在天窗期内对轨枕进行修复施工，该施工方法通过聚合物水泥砂浆进行浇筑养护形成新的道床结构，实现整体道床沉降的快速恢复，该施工方法现场工程量小，聚合物水泥砂浆可以快速硬化道床，缩短道床修复施工工期，大大减少对运营的影响，通过调高扣件使轨底与道床面之间的间隙增大，使其能够满足工务抢修时安装钢轨急救器的空间需要，缩短了应急处置时间，降低对列车运行和乘客出行的影响。
