High-speed rail curve ultrahigh section ballastless track plate replacement method
The invention provides a high-speed rail curve ultrahigh section ballastless track plate replacement method, which relates to the technical field of railway ballastless track structure repair, and comprises the following steps: pre-planting a threaded rod in an early-stage skylight, pouring a leveling platform, chiseling away wide and narrow joints, and clamping and limiting a track plate; the skylight is developed on the day: entering a track car set, assembling an in-situ lifting machine, loosening a fastener and installing a track shifting device, transversely shifting a track, stripping, lifting and moving out a track plate, resetting a steel rail, temporarily supporting, installing the track shifting device, shifting the steel rail aside, cleaning a mortar layer, resetting the track plate, resetting the steel rail, temporarily supporting, combining the track car, finely adjusting the track plate and refilling the mortar layer; recovering and adjusting the line; and follow-up skylight development: chiseling away a leveling platform, repairing an inter-line sealing layer, planting steel bars in a plate replacement area track plate, pouring wide and narrow joints, and finely adjusting the track. The technical barrier that a heavy CRTS II template is difficult to replace in the prior art is overcome, and safe and rapid replacement of the slab ballastless track slab is achieved.
本发明提供了一种高铁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：预植螺纹杆、找平平台浇筑、宽窄接缝凿除、轨道板夹持限位；当日天窗开展：轨道车组入场、组装原位吊运机、松开扣件并安装拨轨设备、横向拨轨、轨道板剥离抬升并移出、钢轨复位、临时支撑、安装拨轨装置、拨开钢轨、砂浆层清理、轨道板复位、钢轨复位、临时支撑、轨道车组合、轨道板精调、砂浆层重新灌注、线路恢复调整；后续天窗开展：凿除找平平台、线间封闭层修复、换板区轨道板植筋、宽窄接缝浇筑、轨道精调。本发明攻克了当前技术难以更换较重的CRTS II型板的技术壁垒，实现对板式无砟轨道板安全、快速的更换。
