If the accumulation of internal stress in steel rails is not effectively controlled, it is extremely prone to cause fractures, which seriously threatens the safety of railway transportation. To do a good job in risk prevention and control, it is necessary to start from multiple aspects.
Monitoring is the primary link in prevention and control. Using ultrasonic flaw detectors, electromagnetic flaw detection equipment, etc., to regularly inspect the steel rails can timely detect minor cracks and stress concentration areas inside the rails. Meanwhile, installing stress monitoring sensors in key sections to collect real-time stress data of steel rails, and predicting stress change trends and providing early warnings of potential risks through big data analysis and intelligent algorithms.
Controlling the generation of internal stress in steel rails is equally important. In the rail laying process, strictly control the construction technology to ensure the welding quality of rail joints and reduce stress concentration caused by welding defects; reasonably set rail gaps, and reserve appropriate gaps according to the expansion and contraction characteristics of steel rails in high-temperature or low-temperature environments to avoid excessive accumulation of temperature stress. In addition, optimize train operation organization, control the speed and load of trains passing through steel rails, and reduce the impact of dynamic stress on the rails.
Maintenance is the key to reducing risks. For steel rails detected with stress hidden dangers, timely take stress relaxation measures to release the accumulated internal stress. For worn or deformed steel rails, carry out grinding or replacement to prevent the further aggravation of local stress. In daily inspections, strengthen the visual inspection of steel rails, observe whether there are surface cracks, spalling and other phenomena. Once abnormalities are found, promptly carry out in-depth detection and repair work. Through the above comprehensive prevention and control measures, the risk of fracture caused by internal stress in steel rails can be effectively reduced, and the safe and stable operation of railway tracks can be ensured.
