I don't know if everyone thinks of "water injected meat" when they see the word "oil injected sleepers". The two may seem a bit similar, but they are completely different things.

In railway construction, sleepers are a very important component that bears the weight of trains and maintains the normal operation of the tracks. However, due to year-round wind and rain, sleepers are prone to corrosion and therefore require anti-corrosion treatment. Usually, anti-corrosion treatment is carried out through oil injection, so anti-corrosion sleepers have the nickname "oil injected sleepers". So the question is, how is the oiled sleeper "oiled"? What kind of oil is injected? Next, let's briefly analyze.

To get straight to the topic, let's learn about the oil injection and anti-corrosion process of anti-corrosion sleepers. Oil injection is a mechanical filling method that uses high-pressure mechanical methods to fill the gaps in the wood with oil according to the pore size and density of the sleepers, in order to achieve the purpose of anti-corrosion. Simply put, it means putting the sleepers into specific equipment containers, using high temperature and high pressure to immerse anti-corrosion oil into the interior of the sleepers, filling the gaps in the wood inside the sleepers with anti-corrosion oil.

The anti-corrosion oils mentioned here are mostly coal tar, deliquescent anthracene oil, or tung oil. Although these anti-corrosion oils have a strong odor and are not suitable for indoor use, the improved anti-corrosion ability after being immersed in sleepers is very pleasing. Moreover, sleepers themselves are not considered indoor items, and their greatest function is still for the laying and normal operation of railway tracks.

So, what are the advantages of the oil injection method for anti-corrosion sleepers? Firstly, wood itself has good permeability, which allows anti-corrosion oil to penetrate more fully into the interior of the wood, fill the pores and voids of the wood, form a uniform anti-corrosion layer, effectively resist insect and fungal erosion, and extend the service life of the sleepers. Secondly, the oil injection anti-corrosion method is simple to construct, easy to operate, and more importantly, it can be processed on site without being limited by seasonal climate. It can be maintained at any time to ensure the safety of railway operation. In addition, oil injection anti-corrosion can also improve the water resistance and wear resistance of wood, with good anti-corrosion effects. It can reduce the frequency of sleeper replacement, lower maintenance costs, and also comply with the concept of sustainable development.

Overall, the oil injection method for anti-corrosion sleepers is of great significance in railway construction and maintenance. By injecting oil, the service life of sleepers can be effectively extended, the safety and stability of railways can be improved, maintenance costs can be reduced, and the unity of economic, environmental and social benefits can be achieved. At the same time, continuous improvement and innovation can also be used to solve some of the problems in the oil injection method, making it more perfect. I hope that in the future, the oil injection method can be more widely used in railway construction, making greater contributions to the development of railway transportation.
