Concrete sleeper damage repairing process
The invention belongs to the technical field of sleeper repairing, and particularly relates to a concrete sleeper damage repairing process which aims at repairing sleeper bearing platform damage and surrounding cracks and comprises the following steps that firstly, a wrench is used for loosening and taking down a fastener system at the position of a to-be-repaired sleeper, and then a hydraulic track jack is used for lifting a steel rail; a working face with a certain height is formed between the sleeper bearing platform and the steel rail bottom plate, a base plate on the sleeper bearing platform is taken down, the damaged portion of the bearing platform is roughened or ground, crushed or loosened concrete is cleaned up, dust and oil dirt on the surface are removed through a steel wire brush, and the repaired sleeper is long in repairing effect lasting time. Repeated arrangement of personnel for maintenance is not needed, a large amount of labor is saved, the construction process is simple in procedure, the operation period is short, the construction difficulty is low, operation is convenient and fast, the maintenance cost can be saved by 50%-80%, the efficiency is improved by more than 10 times, and meanwhile the safety during maintenance operation is effectively improved.
本发明属于轨枕修复技术领域，尤其为混凝土轨枕伤损修复工艺针对轨枕承台破损以及周围裂纹修复，包括以下步骤，首先用扳手松开并取下待修轨枕部位扣件系统，再用液压起道机抬起钢轨，使轨枕承台与钢轨底板之间形成一个高度的作业面，取下轨枕承台上的垫板，对承台破损部位进行凿毛或打磨粗糙，并将压溃或松动的混凝土清理干净，再用钢丝刷将表面的灰尘、油污清除后，修复后的轨枕，修复效果可持续时间长，无需反复安排人员进行检修，节省大量劳力，施工工艺工序简单、作业周期短、施工难度低、操作便捷，维修成本可节省50％‑80％、效率提高10倍以上，同时也有效提高了维修作业时的安全性。
