Why Are Stones Paved On Train Tracks?
The purpose of paving stones on the train track is to increase the stability of the track, improve the driving safety of the train, reduce the impact of the train on the track, and reduce the problems caused by thermal expansion and contraction of the rail. Next, railway equipment manufacturers will give you a detailed analysis!
1. Prevent train derailment. Paving stones on train tracks can increase track friction and prevent trains from derailing due to insufficient friction when traveling at high speeds. Due to the heavy weight and speed of trains, if the track friction is insufficient, trains are prone to derailment accidents, posing safety hazards to trains and passengers.
2. Buffer the impact of the train on the track. The train is a heavy duty vehicle that exerts great impact on the track during travel. If the track is not paved with stones, these impact forces will act directly on the track, causing the track to deform, be damaged, or even break. Paving stones can increase the buffering performance of the track, reduce the impact of the train on the track, and extend the service life of the track.
3. Prevent track deformation. The impact of the train on the track will cause track deformation, especially for some curved tracks, the deformation problem is more serious. Paving stones can increase the rigidity and stability of the track, reduce track deformation, and improve the safety of train driving.
4. Convenient drainage. Railway tracks often encounter rainy weather. If the tracks are not paved with stones, rainwater will accumulate on the tracks, affecting the safety of trains. Laying gravel can increase the drainage performance of the track, drain rainwater from the track in time, and avoid affecting the movement of trains due to water accumulation.
5. Reduce rail temperature. In the hot summer weather, the temperature of the railway tracks will be very high. If cooling measures are not taken, it is easy to cause a train derailment accident. Laying gravel can lower the temperature of the rails, reduce the friction between the train and the rails, and improve the safety of train driving.
In short, laying stones on train tracks has many benefits. It can effectively improve the safety and stability of train driving, extend the service life of the track, and facilitate drainage and cooling. The technical name for these stones is ballast. They are small stones made of granite, basalt, pebbles and other materials. They are generally black or dark brown in color. The laying of these stones requires strict technical requirements and standards, including particle size, gradation, material and other requirements. At the same time, laying ballast also requires regular maintenance and replacement to ensure the quality and service life of the track.
