Concrete filled steel tube sleeper type ballastless track sleeper open joint grout overflow treatment method
The invention discloses a concrete-filled steel tube sleeper type ballastless track sleeper gap and grout overflow treatment method, which belongs to the technical field of railway tracks, and comprises the following steps: detecting a ballastless track, and determining a damaged sleeper and a maintenance area; anchoring embedded steel bars of the roadbed slab in the area where the damaged sleeper is located; removing roadbed slab concrete in the maintenance area; grouting materials are poured into the roadbed slab pits; the fixing fasteners on the damaged sleepers are removed, and temporary supporting fasteners are installed between the steel rails and the embedded sleeves; and the temporary supporting fasteners are dismantled, and the fixing fasteners are installed on the damaged sleepers again so as to position the sleepers. The invention provides a concrete-filled steel tube sleeper type ballastless track sleeper open joint grout emission treatment method, which can complete rapid and accurate treatment of sleeper open joint grout emission when a concrete-filled steel tube sleeper type ballastless track bed has a sleeper open joint grout emission defect, thereby solving the problem of incompactness between a sleeper and a newly poured track bed. And therefore, the problem of sleeper open joint grout emission is fundamentally solved.
本发明公开了一种钢管混凝土枕式无砟轨道轨枕离缝冒浆整治方法，属于铁路轨道技术领域，步骤如下：检测无砟轨道，确定病害轨枕和检修区域；将病害轨枕所在区域的道床板植筋锚固；清除检修区域中的道床板混凝土；采用注浆材料灌注道床板坑中；拆除病害轨枕上的固定扣件，并在钢轨和预埋套管之间安装临时支撑扣件；拆除临时支撑扣件，并重新在病害轨枕上安装固定扣件以定位轨枕。本发明提供了一种钢管混凝土枕式无砟轨道轨枕离缝冒浆整治方法，能够在钢管混凝土枕式无砟道床出现轨枕离缝冒浆缺陷时完成对轨枕离缝冒浆的快速准确的处理，进而解决轨枕与新浇筑道床间的不密实问题，进而从根本上解决轨枕离缝冒浆病害。
