What do you need to pay attention to when purchasing railway ties? This problem relates to an important link in railway construction and maintenance, because sleepers play a pivotal role in railway transportation. The right way to buy can not only improve the safety and stability of the railway, but also extend the service life of the railway facilities. The following Qingdao Tiehan and everyone together to analyze the aspects that need to pay attention to when choosing railway ties.
First of all, when purchasing railway ties, the primary consideration is its material. There are many kinds of railway sleepers, including wood sleepers, concrete sleepers and plastic sleepers. Sleepers of different materials have their own characteristics and need to be selected according to the specific situation.
Wooden sleepers are the traditional choice, mainly with trees as raw materials, after processing. Wood sleepers have the advantages of light weight, easy processing, easy to replace, but its disadvantages are easy to be damp, easy to rot, short life and so on. Of course, after the special anticorrosive treatment of wooden sleepers, it has greatly improved the problems such as susceptibility to moisture and corruption, and its service life has been greatly extended. Usually after anticorrosive treatment of wooden sleepers, we call it "anticorrosive sleepers" or "oil soaked sleepers".
Concrete sleepers are a relatively new option, mainly made of cement, gravel and other raw materials mixed. Concrete sleeper has the advantages of durability, pressure resistance, corrosion resistance, etc., which is suitable for wet environment and high-speed railway. However, its disadvantage is that the construction is more complicated, the adjustment is inconvenient, and the price is high, and the maintenance is difficult.
The more special plastic sleeper is an environmentally friendly material, mainly made of recycled plastic. Plastic sleeper has the advantages of light weight, corrosion resistance, easy installation, and has good moisture and corrosion resistance, long life. However, its disadvantage is that its strength is not as strong as concrete sleepers, and it needs to make reasonable adjustments in design. And its cost and cost relative to wooden sleepers and concrete sleepers are much more expensive, if a wide range of use, the construction cost is likely to double.
In fact, among the many railway ties, anticorrosive ties are a popular choice. Anticorrosive sleepers are treated with oil impregnation on the basis of wooden sleepers to extend their service life and reduce maintenance costs. Anticorrosive sleepers not only have the advantages of wooden sleepers, but also have the durability second only to concrete sleepers, and are suitable for various railway environments. At the same time, anticorrosive sleepers can also reduce railway maintenance costs, extend the service life of sleepers, and have good economic benefits.
In the construction and maintenance of railway, the correct selection and use of railway sleepers is very important. Therefore, the purchase of railway ties needs to consider many aspects, including material, environment, price and other factors. Different materials of sleepers have advantages and disadvantages, need to be selected according to the actual situation. The anti-corrosion sleepers are more excellent in many railway sleepers, and its advantages are corrosion resistance, long life, low maintenance costs, and it is the only choice for modern railway construction and maintenance.
