Existing line long sleeper embedded ballastless track bed deviation regulation method
The invention belongs to the technical field of ballastless track deviation correction, and particularly relates to an existing line long sleeper embedded ballastless track bed deviation regulation method. The method is executed in a skylight period and comprises the following steps: S1, determining a deviation value between a current rail surface line type and a target line type in a deviation correction area; s2, counter-force piers are arranged on the two sides of the line; s3, the track plate is dissociated; s4, concrete at the starting point and the terminal point of the track plate deviation rectifying unit is chiseled away; s5, the track plate is lifted; s6, transverse limiting is relieved, and a transverse loading mechanism is arranged between the track plate and the counter-force pier for transverse deviation correction; s7, after the track plate is rectified to the target line type, a lower void layer of the track plate is repaired; after the void layer repairing material reaches the design strength, embedded steel bar anchoring is carried out on the dissociation range of the track plate and the base plate in a sleeper-by-sleeper mode; the steel rail is not influenced in the deviation rectifying process, the process is simple, the controllability is good, and the problem that the overall weight of a ballast bed is too large and is difficult to renovate is solved.
本发明属于无砟轨道纠偏技术领域，具体涉及一种既有线长枕埋入式无砟道床偏移的整治方法；在天窗期执行，包括以下步骤：S1：确定纠偏区域现轨面线型与目标线型的偏差值；S2：在线路两侧设置反力墩；S3：解离轨道板；S4：凿除轨道板纠偏单元起点、终点处混凝土；S5：抬升轨道板；S6：解除横向限位，在轨道板与反力墩之间设置横向加载机构进行横向纠偏；S7：轨道板纠偏至目标线型后对轨道板下脱空层进行修复；脱空层修补材料达到设计强度后，对轨道板与底座板解离范围逐枕进行植筋锚固；纠偏过程中不会对钢轨产生影响，工艺简单，可控性好，解决道床整体重量过大难以整治的问题。
