Precautions for replacing railway sleepers
Matters needing attention
Safety first:
During the replacement process, the safety operation procedures must be strictly observed to ensure the safety of personnel and equipment.
Avoid replacement work in bad weather or at night to reduce safety risks.
Quality assurance:
The new steel sleeper of qualified quality is selected to ensure the stability and safety of the replaced track.
Install and adjust in strict accordance with technical requirements to avoid loosening, dislocation and other problems.
Construction efficiency:
On the premise of ensuring quality and safety, improve construction efficiency and reduce the impact on railway transportation.
Arrange the construction plan reasonably to ensure that the replacement work can be completed on time.
Consideration of special circumstances:
When replacing the sleeper on the open line, the rail cannot be lifted for replacement.
When replacing the bridge tie, it is necessary to pay attention to the thickness and height of the ballast plate, and take appropriate measures to replace it.
When the sleeper is replaced, the deviation of the rail temperature should be within a certain range to avoid adverse effects on the stability of the track.
