[0002] Concrete sleepers are concrete products widely used in railways. They replace traditional wooden sleepers and have the advantages of saving wood, long service life, good quality of laid tracks, less maintenance work, and low cost. Concrete sleepers can be divided into integral, combined, and semi-sleepers. According to the reinforcement method, they can be divided into reinforced concrete sleepers and prestressed reinforced concrete sleepers. According to the prestress application method, they can be divided into pre-tensioning method, post-tensioning method, and continuous reinforcement method, etc. According to different rail gauges, concrete sleepers also have corresponding specifications, such as sleepers for standard gauge and narrow gauge. The structural design of concrete sleepers aims to ensure that they can effectively support the rails, maintain the rail gauge, and transfer the load transmitted by the train through the rails to the roadbed. The design of sleepers usually includes prestressed steel bars, steel wires, nylon sleeves, and reserved holes or embedded iron parts for installing fasteners.

[0003] During the long-term use of rail transit, its tracks will show phenomena such as wear, impact, and natural aging. Especially in the long-term use process of nylon sleeves in vehicle depots, parking lots, and main line sections, problems such as thread slipping and failure will start to occur. In particular, some bottom bolts break inside the nylon sleeves and cannot be removed, resulting in the failure of the nylon sleeves. For the safety of rail transit, they need to be replaced. During the replacement process, the replacement is mostly carried out by using a water drill to take cores and perform anchoring operations. However, when fixing and installing the water drill, the traditional method mostly uses expansion bolts to fix it on the roadbed and the sleeper surface, and its stability is poor and the safety cannot be guaranteed.
