In recent days, snow has become a hot topic in various parts of northern China. As a relatively special weather phenomenon, snow can be said to be both loved and hated. What I love is the silver coating of snow, and the auspicious snow symbolizes a bountiful year; What I hate is that snow makes the road very slippery. The heavy snow weather has a great impact on traffic, and the snow that has not been cleared in time on the road is very slippery after being rolled over, which greatly affects driving safety. So, what impact will heavy snowfall have on anti-corrosion sleepers on railways?
The key point of the problem is to understand the impact of heavy snow on anti-corrosion sleepers, and we first need to understand the structure of anti-corrosion sleepers. Everyone knows that snowflakes are another form of water, while anti-corrosion sleepers are not afraid of water. The obvious difference is that the temperature of snow is lower. However, the anti-corrosion sleepers are soaked in anti-corrosion oil inside and do not have much moisture, so they are not afraid of internal freezing and cracking even at low temperatures. On sunny days after snow, when the snow melts, it all turns into water, and the water flows through the anti-corrosion sleepers, with little impact on them.
Anti corrosion sleepers mainly prevent the erosion of fungi and other microorganisms, while snow has a relatively small corrosive effect on wood, so the corrosion effect of snow on anti-corrosion sleepers is not significant. This is different from other environmental corrosion factors such as moisture and sunlight. So, compared to other forms of weather conditions, although snow has an impact on anti-corrosion sleepers, it is not its main test and has little impact on the service life of anti-corrosion sleepers.
Moreover, anti-corrosion sleepers also have their unique advantages in heavy snow weather. For example, as we just mentioned, anti-corrosion sleepers have high waterproof performance, which allows them to maintain good anti-corrosion effects even in heavy snow weather. Even under heavy snow cover, anti-corrosion sleepers can effectively prevent moisture from seeping in, thereby extending their service life. This has a very positive effect on ensuring the normal operation of railways.
In addition, anti-corrosion sleepers adopt various anti-corrosion technologies, such as chemical anti-corrosion and vacuum pressure treatment, making them have strong corrosion resistance in harsh environments. Therefore, even in heavy snow weather, anti-corrosion sleepers can maintain their structure and performance relatively stably and are not easily affected by the external environment.
Another thing that many people may not have expected is that anti-corrosion sleepers are black, which is easier to absorb heat under sunlight. However, if there is not a bit of snow covering, as soon as the sun comes out, the sleepers that quickly absorb sunlight heat will promote the melting of snow. The rapid melting of snow reduces the impact of accumulated snow on railways, indirectly ensuring the safety and stability of the railway system.
Therefore, in heavy snow weather, although anti-corrosion sleepers on railways may face certain impacts and challenges, their unique anti-corrosion performance, stability, and good durability enable them to still play their due role in harsh environments, ensuring the normal operation of the railway system. This is also the important value of anti-corrosion sleepers in railway use.
