Rapid pushing and replacing construction method for ballastless track structure of passenger special line
The invention discloses a rapid pushing and replacing construction method for a ballastless track structure of a passenger special line. The method comprises the process of renovating a disease area by adopting a detachable inverted arch structure. The process is divided into three stages of a preparation stage, a key stage and a recovery stage. The key stage at least comprises the steps of chiseling away grooves and roadbed slabs in a segmented mode, erecting temporary steel beams, laying wooden sleeper track panels, excavating a bottom of a tunnel, disassembling and replacing inverted archesand filling layers, carrying out end prestress anchoring and reinforcing, and carrying out roadbed pouring. In the process of chiseling away the grooves and track plates in the segmented mode, the track plates are pushed out of the grooves in a segmented and blocked mode, construction efficiency is high, a speed is high, and safety is good; and construction skylight is used for operation and railway operation line construction, influences of factors such as traffic safety, construction boundaries, technological processes and the like are considered, and the construction method and steps are reasonable in arrangement.
本发明公开一种客运专线无砟轨道结构快速推移更换施工方法，包括采用拆换仰拱结构对病害区域进行整治的过程，分为三个阶段：准备阶段、关键阶段和恢复阶段；所述关键阶段至少包括分段凿除沟槽及道床板、架设钢便梁、铺设木枕轨排、隧道底开挖拆换仰拱及填充层、端部预应力锚固加固、道床浇筑的步骤；在分段凿除沟槽及轨道板中，通过分段、分块的方式将轨道板推移出槽，施工效率高、速度块、安全性好；利用了施工天窗进行作业、铁路运营线施工，考虑到行车安全、施工界限、工艺流程等因素影响，施工方法和步骤安排合理。
