For the railway track swaying problem, it is necessary to start from the root cause and take systematic and effective control measures to ensure the safe and smooth operation of trains.
In the adjustment of track geometry, advanced detection equipment such as track inspection vehicles and total stations should be used to regularly measure parameters such as gauge, level, height, etc. Once the gauge is found to be over-limit, the gauge adjuster should be used to adjust it immediately; for the level unevenness, the two rails can be kept level by starting and tamping operations. For the uneven height areas, precise tamping technology is used to eliminate the height deviation of the track and restore the track smoothness.
In terms of rail maintenance, it is necessary to strengthen the flaw detection of rails and timely detect rail wear, cracks, hard bends and other diseases. For severely worn rails, they should be replaced in time; for hard bends of rails, rail straightening machines should be used for straightening. At the same time, the rail joint process should be optimized to ensure the flatness of the joints, reasonably control the size of the rail gap, use high-strength bolts and spring clip fasteners, enhance the stability of the rail joints, and reduce vibration when the train passes.
Ballast treatment is the key to improving track stability. For dirty and compacted ballasts, clean and screen them to remove crushed stone powder and debris in the ballast and restore the elasticity of the ballast. If the ballast thickness is insufficient or the shoulder width is insufficient, add ballast in time to ensure that the ballast meets the specified thickness and shoulder width standards, and enhance the support and lateral resistance of the ballast.
In the face of external environmental influences, before the arrival of the high temperature season, stress relief is carried out on the rails to prevent track expansion; in low temperatures, rail inspections are strengthened to deal with rail cracks in a timely manner. For areas with poor geological conditions, grouting reinforcement and foundation replacement are used to improve the stability of the roadbed and reduce track deformation caused by roadbed settlement. Through multi-pronged treatment measures, the problem of railway track shaking is effectively solved.
