Ballastless track damaged sleeper replacement method
The invention discloses a high speed railway ballastless track damaged sleeper replacement method which comprises the following steps: firstly, removing the damaged sleeper, then mounting and fixing anew sleeper, and pouring the new sleeper and a track plate into a whole again; cutting at a proper depth at the boundary of a forcible entry range; adopting high-pressure water jet to cut the area within the forcible entry range; cutting off a plurality of longitudinal reinforcing steel bars in the track plate; carrying out sleeper replacement and fixation, connecting the plurality of cut off longitudinal steel bars; pouring concrete or mortar at the forcible entry part to pour the new sleeper and the track plate into a whole, carrying out leveling maintenance, and temporary supporting on thetwo sides of the replaced sleeper, before skylight time is over, loosening fastener bolts on the sleeper again, removing a base plate below the sleeper, and recovering fasteners after the strength ofthe poured concrete or mortar reaches the designed strength. By means of the method, new cracks cannot be formed in existing concrete, original structural steel bars cannot be damaged, the construction range is accurate, the interface of the dismantled concrete is rough, the binding power is high, binding of new concrete and old concrete is facilitated, and the integrity is better.
高速铁路无砟轨道伤损轨枕更换方法,包括：更换步骤为先拆除已经伤损的轨枕，然后安装新轨枕固定后，重新将新轨枕与轨道板浇筑成整体。在所述破拆范围的边界进行适当深度的切割，采用高压水射流切割所述破拆范围内的区域，将轨道板内多条纵向钢筋截开，轨枕替换并固定，将截断的多条纵向钢筋连接，破拆部位浇筑混凝土或砂浆将新轨枕与轨道板浇筑成整体并进行并整平养护，对替换轨枕的两侧进行临时支撑，天窗时间结束前，重新松开轨枕上的扣件螺栓及，撤除轨枕下的垫板，待浇筑混凝土或砂浆强度达到设计强度后恢复扣件。该方法不会在既有混凝土内形成新的裂缝，不破损原结构钢筋，施工范围精确，且拆除后的混凝土界面粗糙，粘结力强，有利于新旧混凝土的粘结，整体性更好。
