How To Deal With Track Bulging Runway

- Jul 28, 2018-


1. When the line continuously appears 3 to 5mm, it is necessary to strengthen the inspection or special surveillance, observe the change of the direction of the rail and the direction of the line. If the broken bend continues to expand and expand, the slow line signal should be set. After the emergency treatment line is stable, the normal running speed will be restored.

2, in the maintenance and maintenance work, the track is found, the height is bad, the road, the dialing of the road are saved, the ballast at the end of the pillow is separated from the seam, and the operation must be stopped and the measures of anti expansion are taken in time.

3. After the operation or operation, it is found that the track direction is bad, the 10 meter string quantity of two strands of rail and the rail alignment are different. When the average value is up to 10mm, the slow line must be set, and the rammed ballast bed is adopted, the pillow box ballast and the high ballast shoulder are filled. When the average deviation of the track deviation of the two rail is reached, the temperature of the rail is unchanged at the same time. In case of the sudden expansion of the deflection of the line after passing the train, the stop signal must be immediately set to release the train after the fault is eliminated.

4. After the rail expansion runway, water can be taken to reduce the rail temperature. After the rail temperature is reduced, the path can only be dialed. The curve section can only be unsuitable for the lower pressure. After the dialing, the ballast bed must be rammed and the high ballast shoulder is piled. The speed limit release train is reached when the speed limit of the train is reached, and the rail temperature drops to the locked rail temperature, then restore the line again. Normal running speed.


5. When the workshops and the workshops have been informed of the failure, the director of the workshop or the head of the workshop should send people to protect the station. At the same time, they should quickly organize the emergency personnel, prepare the emergency equipment and materials, and rush to the scene for the repair. And maintain communication at any time, timely reporting to the higher authorities on the scene.
