High-speed railway ballastless track arching disease treatment construction method
The invention relates to the technical field of railway ballastless track maintenance and repair, in particular to a high-speed railway ballastless track upwarp disease treatment construction method which comprises the steps of skylight preparation stage construction, skylight polishing stage construction and skylight recovery stage construction. In the skylight preparation stage, the upward arching amount and the fastener current situation of an upward arching disease section are determined by measuring a track, in the skylight polishing stage, the track bed foundation elevation is reduced by dismantling a fastener system, polishing a track bearing table and conducting line recovery operation, and in the skylight recovery stage, the track is measured, the fasteners are finely adjusted, and the line smoothness is recovered. And upward arch disease treatment and normal-speed line operation recovery are realized. The method has the advantages of high renovation efficiency, skylight point operation, less line foundation disturbance, low labor intensity of operators and the like.
本发明涉及铁路无砟轨道养护维修技术领域，尤其是一种高速铁路无砟轨道上拱病害整治施工方法，包括准备天窗阶段施工、打磨天窗阶段施工以及恢复天窗阶段施工；在准备天窗阶段通过对轨道进行测量确定上拱病害区段的上拱量和扣件现状，在打磨天窗阶段通过对扣件系统拆除、承轨台打磨、线路恢复作业降低道床基础标高，在恢复天窗阶段通过对轨道测量、扣件精调，恢复线路平顺性，实现上拱病害整治，线路恢复常速运营。本发明的优点是：整治效率高、天窗点作业、线路基础扰动少、作业人员劳动强度低等特点。
