Polishing construction operation method for ballastless track bearing platform of high-speed railway
The embodiment of the invention provides a high-speed railway ballastless track bearing table polishing construction operation method which comprises the steps that ballastless track upward arching disease line section data are collected through a track inspection trolley, and the polishing amount of a bearing table is determined; the locking rail temperature is measured, and key parameters of the grinding area are marked; according to the actual temperature and the locking rail temperature, the number of disassembled fasteners in the extending direction of the steel rails at the two ends of the grinding area is determined; the rail bearing table polishing device is close to the adjacent line of the to-be-polished area to carry out polishing operation; the polishing device automatically walks, positions, adjusts and carries out circumferential profiling polishing, and high-pressure water is used for cooling and dust suppression in the operation process; the fastener system recovers the line according to the principle that the polishing amount is consistent with the pad amount; the rail bearing table polishing device is driven away from the operation area from the adjacent line; by the adoption of the method, only the rail bearing table is polished, a ballast bed, a steel rail and an off-line foundation are not affected, and damage to an original concrete structure is small; the method has the characteristics of short construction period, high construction efficiency, low construction cost, high operation quality and the like.
本申请实施例提供一种高速铁路无砟轨道承轨台打磨施工作业方法，包括：通过轨检小车采集无砟轨道上拱病害线路区段数据，并确定承轨台的打磨量；测量锁定轨温，并对打磨区域的关键参数进行标记；根据实际温度与锁定轨温确定打磨区域两端钢轨延伸方向的扣件拆除数量；承轨台打磨装置靠在待打磨区域邻线开展打磨作业；打磨装置自走行、定位、调整以及开展圆周仿形打磨，作业过程中高压水冷却和抑尘；扣件系统按照“打磨量与垫量一致”原则恢复线路；承轨台打磨装置从邻线驶离作业区域；采用本申请，仅打磨承轨台部位，对道床、钢轨、线下基础无影响，对原有混凝土结构伤损小；具有施工周期短、施工效率高、施工成本低、作业质量高等特点。
