Sleeper disengaging treatment construction method for long sleeper embedded type ballastless track
The invention belongs to the technical field of ballastless track renovation, and particularly relates to a sleeper void renovation construction method for a long sleeper embedded ballastless track, which comprises the following steps of: 1, cleaning impurities and loose concrete at a long sleeper gap and a damaged part of a roadbed slab; the position of a grouting opening is determined on the roadbed slab, a hole is drilled in the position of the grouting opening, a side drainage hole is formed in the proper position of one side between the long sleeper and the roadbed slab, and a water stop needle hole is formed in the grouting opening; limiting and pressing devices are arranged on the two sides of the roadbed slab, and one ends of the limiting and pressing devices are pressed on the long sleepers; water stop needle tubes are sequentially arranged in the water stop needle holes; a double-component grouting material is prepared according to the proportion, and a grouting machine is used for being connected with the water stop pinholes in sequence for grouting; and the grouting material is completely cured. The defects in the prior art are overcome, the disengaging damage position between the ballast bed and the sleeper is effectively repaired, the technology is simple, the operation efficiency is high, repairing can be completed within the skylight point time of the high-speed rail, and normal operation of a line is not affected.
本发明属于无咋轨道整治技术领域，具体涉及一种长枕埋入式无咋轨道的轨枕脱空整治施工方法，步骤一、清理长轨枕离缝及道床板破损处的杂质和疏松混凝土；在道床板上确定注浆口位置，并在注浆口位置钻孔，在长轨枕与道床板间一侧合适位置设置侧边排水孔，在注浆口内设置止水针孔；道床板的两侧设置限位压紧装置，限位压紧装置的一端压合在长轨枕上；在止水针孔内依次安装止水针管；按照比例配置双组份注浆材料，利用注浆机依次与止水针孔连接注浆；待注浆材料完全固化。克服了现有技术的不足，对道床与轨枕之间的脱空破损处进行有效的修补，工艺简单、操作效率高，可以在高铁天窗点时间内完成，不影响线路的正常运营。
