If you search for photos of old sleepers online, you will find that most of them have more or less cracks, which is a common problem with wood materials. Similarly, mining area anti-corrosion sleepers made from wood can also crack when used for too long and lacking maintenance. The problem of sleeper cracking involves the quality and safety of sleepers, which directly affects the smooth transportation in the mining area. So, why do anti-corrosion sleepers in mining areas crack? What are the ways to prevent or reduce the cracking of sleepers in mining areas? Next, Qingdao Tiehan will briefly analyze with everyone.
No matter what material is used to make sleepers, they will be affected by the supporting state of the environment they are in. Similar to our common cement sleepers, the support state of anti-corrosion sleepers will constantly change with the operation and maintenance conditions of the train. Once the torque caused by the combined action of the support state and the pressure on the sleeper exceeds the limit that the sleeper can withstand, cracks will occur in the corresponding parts of the anti-corrosion sleeper. The difference between wooden anti-corrosion sleepers and cement sleepers in this regard is that wooden anti-corrosion sleepers will crack, while cement sleepers will shatter and fall off.
Of course, it's not just about the supporting state, the reason for the cracking of anti-corrosion sleepers in mining areas is also related to the environment. In the environment of the mining area, sleepers are easily affected by various external pressures and damages due to factors such as cold, hot, dry, wet, and vibration. The invasion of the environment, combined with the pressure and vibration generated by frequent transportation of minerals by mining trucks, can lead to cracking over time when the toughness fatigue of the sleepers reaches the threshold. If maintained in a timely manner, it can also prevent cracking from becoming more severe. If not maintained in a timely manner, cracking will only become more and more severe until it may affect safety and be replaced.
In addition to environmental factors, the cracking of anti-corrosion sleepers in mining areas is also related to improper human operation. During transportation and installation, if the operation of sleepers is not standardized, it will bring unnecessary pressure and damage to the sleepers, leading to cracking. For example, failure to take appropriate protective measures during transportation, or failure to operate according to specifications during installation, can have an impact on the quality of sleepers.
So, what are the ways to prevent or reduce cracking of anti-corrosion sleepers in mining areas? Firstly, it is important to choose high-quality materials to ensure that the wood undergoes good anti-corrosion treatment. Secondly, during the use of sleepers in mining areas, attention should be paid to maintenance. If any signs of cracking are found, anti loosening iron wires can be tied in a timely manner for reinforcement. Furthermore, it is necessary to standardize operations to ensure that unnecessary damage to sleepers is avoided during handling, transportation, and installation.
Overall, cracking of anti-corrosion sleepers in mining areas is a problem that needs to be taken seriously, as it directly affects the quality and safety of mining engineering construction. By selecting high-quality sleepers reasonably, paying attention to maintenance during use, and standardizing operations, the probability of sleeper cracking can be effectively reduced, thereby ensuring the smooth transportation of mining areas. I hope that the relevant engineering personnel in the mining area can pay attention to this issue and take effective measures to solve it.
