Method for replacing and repairing operation high-speed rail ballastless track extruded sheet
The invention provides an operation high-speed rail ballastless track extruded sheet replacing and repairing method, and relates to the technical field of railway ballastless track structure repairing. Edge sealing structures are arranged on the two sides of a line at the design position of the original damaged extruded sheet and the exposed end of the beam end, and a grouting area is formed; a grouting pipe is inserted into the grouting area, and a grouting material is evenly injected into the grouting area according to the amount of the grouting material needed by the grouting area; the grouting pipe is taken out, and a temporary pressing device is arranged on the base plate on the upper side of the grouting area; and the grouting material reacts and expands, the grouting area is densely filled, and the extruded sheet is obtained after curing. According to the method, after the original damaged extruded sheet is thoroughly removed, the material similar to the extruded sheet is cast in situ, so that the extruded sheet is rapidly replaced and repaired within the skylight time, and meanwhile, the problems that filling is not full, and the applicability and matching performance of the repairing material and the original extruded sheet material are poor in function are solved.
本发明提供了一种运营高铁无砟轨道挤塑板更换修复方法，涉及铁路无砟轨道结构修复技术领域，包括：清理原劣损挤塑板及灰尘；在原劣损挤塑板设计位置的线路两侧及梁端裸露端设置封边结构，形成注浆区域；在注浆区域插入注浆管，根据注浆区域所需注浆材料用量向注浆区域均匀注入注浆材料；取出注浆管，针对注浆区域上侧的底座板设置临时压紧装置；注浆材料反应膨胀，将注浆区域填充密实，固化后得到挤塑板。本发明通过彻底清除原劣损挤塑板后现浇与挤塑板材质相近的材料，实现天窗时间内挤塑板的快速更换修复，同时解决现有技术填塞不饱满、修复材料与原挤塑板材料功能的适用性和匹配性差等问题。
