For loose or damaged sleepers, grouting materials (such as epoxy resin) can be used for reinforcement. The sleeper is usually fixed to the rail by fasteners or other reinforcement structures.

[0003] For example, in a railway sleeper reinforcement structure disclosed in the existing patent publication number CN219772562U, it includes a sleeper body, and an adjustment and fixation mechanism is arranged on the top of the sleeper body; the adjustment and fixation mechanism includes a rail fixedly connected to the top of the sleeper body, a limit seat fixedly installed on the top of the sleeper body, a limit plate fixedly installed inside the limit seat, a pressing piece fixedly installed on the side of the limit plate close to the rail, and a bolt threadedly connected to the inside of the limit plate and threadedly connected to the top of the sleeper body; by pushing the limit plate and rotating the threaded rod, the pressing piece and the fixing piece are moved for fixation or released from fixation, which is convenient for disassembling the device.

[0004] When the above reinforcement structure is used for reinforcement, grooves corresponding to the fixing piece and grooves corresponding to the bolt need to be opened on the sleeper. Both the pressing piece and the fixing piece slide horizontally, and the fixation stability of the rail still needs to be improved, and the stable fixation between sleepers still needs to be improved.
