Recently, the north of China has suffered continuous freezing rain weather, which is easy to lead to slippery road weather to people's life and traffic has brought a lot of troubles. Taking Qingdao, Shandong Province as an example, in the past two or three days, heavy snow, sleet and freezing rain came in turns, and a layer of snow and ice on the highway caused a very serious impact on people's travel. Of course, for the anticorrosive tie of the switch on the railway, the impact of freezing rain can not be ignored. But at the same time, wood anticorrosive sleepers in the face of freezing rain weather also revealed its unique advantages.
Not only on roads, the main effect of freezing rain on railway and turnout anticorrosive ties is icing and freezing. Due to the special weather of freezing rain, rain water is easy to freeze into thin ice when it comes into contact with the ground and most materials of sleepers, which will increase the weight of the sleepers and affect its carrying capacity. In addition, if the freezing rain weather continues for a long time, it may also form thick ice on the surface of the tie, further increasing the load on the tie, causing it to become fragile and fragile.
However, compared with sleepers of other materials, wooden anti-corrosion pillows do not have their unique advantages and adaptability. First, wood anticorrosive sleepers usually have higher toughness and elasticity, which means that they are better able to resist the pressure brought by the external ice and are not easy to crack and break in cold weather. Secondly, due to the particularity of the wood anticorrosive sleeper production process, its interior is mostly filled with anticorrosive oil, and it is not easy to crack in the frozen low temperature environment, which can reduce the pressure caused by icing and freezing and maintain its strength and stability.
Whether it is heavy snow, sleet or freezing rain, it always turns into water when the weather warms up. For ordinary sleepers, the water can easily penetrate into the interior of the sleepers and accelerate the corrosion of the sleepers. The wood anticorrosive sleeper due to the special anticorrosive treatment, has strong anticorrosive properties, can effectively prevent water infiltration into the sleeper, so as to resist the corrosion factors, to extend the purpose of the sleeper life.
On the other hand, wood anticorrosive sleepers are also easier to repair and maintain in the face of freezing rain. Compared with other materials, wooden ties can be more easily repaired and replaced after being affected by freezing rain and ice, and maintenance personnel can also use conventional methods to maintain them to ensure the normal operation of the turnout.
In summary, although the freezing rain weather has no small impact on the railway sleepers, the advantages of wood anticorrosive sleepers in dealing with this weather situation are still obvious. Its elasticity and toughness can reduce the pressure caused by the external ice, corrosion resistance can maintain the long-term stable use of the sleeper, while easy maintenance and replacement also ensure the safe operation of the switch. Therefore, in railway construction, wood anticorrosive sleepers are still a reliable choice, especially in the face of bad weather, it shows the reliability and adaptability is more prominent. It is hoped that in the future development of railway, wood anticorrosive sleepers can be more widely used and contribute more to the safety and stability of railway transport.
