[0002] The sleeper bolt is the main component of the railway track. Its function is to guide the wheels of the locomotive and vehicle forward, bear the huge pressure of the wheels, and transmit it to the sleeper. Its main material is carbon steel, which has high strength and hardness, high elastic limit and fatigue limit. After long-term use, the sleeper bolt will cause structural damage due to rust, and it will not meet the use requirements and affect driving safety. Therefore, the sleeper bolt needs to be replaced regularly. The specific method is: manually use a drilling machine to drill the sleeper bolts, and then re-pour concrete to anchor the new sleeper bolts to meet the use requirements and improve driving safety.
