Method for replacing ballastless track slab of curve ultrahigh section of high-speed railway subgrade section
The invention provides a high-speed rail roadbed section curve ultrahigh section ballastless track plate replacement method, and relates to the technical field of railway ballastless track structure repair, and the method comprises the following steps: chiseling off the connection between a track plate to be replaced and a base as well as between adjacent track plates in early skylight time, and clamping and limiting; in the sunroof time of the day, the rail car group is grouped and enters the yard on the adjacent line, the plate conveying trolley is hoisted to the rail line through the rail crane, and a new rail plate is hoisted to the plate conveying trolley and is transported to the outside of the rail shifting area; a walking type lifting machine is assembled on the track line, a limiting device is disassembled, a fastener is loosened, and transverse track shifting is carried out; the lifting machine travels to the plate conveying trolley, and the new track plate is lifted to the position near the track plate to be replaced; the lifting machine travels to the track plate to be replaced, lifts the track plate to the plate conveying trolley, and lifts a new track plate to the position of the track plate to be replaced; resetting the steel rail, finely adjusting a new track plate, and pouring cement mortar. According to the invention, hoisting and replacement of the adjacent track plate at the curve ultrahigh section are realized, and the construction efficiency is greatly improved.
本发明提供了一种高铁路基段曲线超高段无砟轨道板更换方法，涉及铁路无砟轨道结构修复技术领域，包括：前期天窗时间，凿除待更换轨道板与底座及相邻轨道板间的连接，并夹持限位；当日天窗时间，轨道车组在相邻线路编组入场，通过轨道吊将运板小车吊至本轨道线，新轨道板吊运至运板小车上，运至拨轨区外；在本轨道线路组装走行式吊运机，拆除限位装置，松开扣件，进行横向拨轨；吊运机走行至运板小车，将新轨道板吊运至待更换轨道板附近；吊运机走行至待更换轨道板，将其吊运至运板小车，并将新轨道板吊运至待更换轨道板位置；复位钢轨、精调新轨道板、浇筑水泥砂浆。本发明实现了在曲线超高段对邻线轨道板吊装及轨道板的更换，大幅提高施工效率。
