Lifting device for repairing differential settlement ballastless track and construction method
The embodiment of the invention discloses a lifting device for repairing a differential settlement ballastless track. The lifting device comprises a connecting rod and a lifting part. The connecting rod is arranged in an expansion joint between a normal ballastless track and a ballastless track to be lifted in a penetrating mode, and the bottom of the connecting rod is lower than the bottom of the ballastless track to be lifted. The lifting part is connected to the end, close to the to-be-lifted ballastless track, of the connecting rod, located below the to-be-lifted ballastless track and connected with the to-be-lifted ballastless track in an abutting mode. When the ballastless track needs to be lifted, only the connecting rod needs to be lifted, so that the lifting part on the connecting rod drives the ballastless track to be lifted to the preset height. The lifting device for repairing the differential settlement ballastless track has the advantages of being simple in structure, convenient to assemble and disassemble, low in manufacturing cost, small in disturbance to the ballastless track and the like. The invention further provides a construction method for lifting the differential settlement ballastless track, and the lifting device provided by the embodiment of the invention is used for repairing and has the advantages of being simple in repairing operation, high in construction efficiency and small in disturbance to the ballastless track.
本申请实施例公开了一种差异沉降无砟轨道修复的抬升装置，包括连接杆以及抬升部。连接杆穿设于正常无砟轨道与待抬升无砟轨道间的伸缩缝中，连接杆的底部低于待抬升无砟轨道的底部；抬升部连接于连接杆靠近待抬升无砟轨道的一端，并位于待抬升无砟轨道的下方，与待抬升无砟轨道抵接。只需抬升连接杆，以使连接杆上的抬升部带动待抬升无砟轨道抬升至预设高度。本申请实施例提供的一种差异沉降无砟轨道修复的抬升装置，具有结构简单、便于装拆、制造成本低，且对无砟轨道扰动小等优点。本申请同时还提供一种差异沉降无砟轨道抬升的施工方法，通过本申请实施例提供的抬升装置进行修复，具有修复操作简单，施工效率高，对无砟轨道扰动小的优点。
