What opportunities does the railway bring, can you talk about it?

It is said that if you want to get rich, you must first build roads, and I think that's right. Our home was originally a small place in the middle of nowhere, but after the railroad was built, everyone said that the mountains and rivers here were good, and it became a tourist attraction, and there were more people. There are more of us in the service industry.

The industrial chain in the village has also undergone great changes, and everyone's work is more intelligent and closer to the current era. More and more children are aware of the importance of reading and studying well, which also increases their desire to get out of the mountains.

I think it has brought a lot of opportunities for single young lads in my hometown to flirt with girls, and there are many girls in the city who come in to play, and bring a boyfriend back when they go home, which feels that it has increased the population span of our hometown, and it is also more conducive to going out of our hometown.

It is also much more convenient for our village to get around. In the past, most of the old people and middle-aged people in the village would stay in the village for the rest of their lives, and they couldn't go out and didn't want to go out, because it was too troublesome to go out. Now with the railway, it is also convenient for everyone to travel, and it can also let everyone see the outside world, and also go out to work to experience the feeling of working outside, which is convenient for all walks of life to communicate with each other.

First of all, the most intuitive is to add some jobs. There are also some posts for railway workers who are specially stationed at the railway crossing, which are all competitive positions and do not require much education, and the villagers think it is very good.

After the railway, the village has been paid more attention by the state, and at the same time, the support of various industries in the village and township has also been high, which can be more conducive to our own entrepreneurship.

After the railway was established, the express company could also take the railway to deliver goods, and some electrical appliances were replaced at home. Now it is much easier to cultivate the land than before, and the harvest of what is planted is higher, and it is easier to sell, because the big trains are coming in. Very comfortable.

The introduction of talents in the village has also become more convenient, and many college students who have gone out in the village are also willing to return to the village to start a business after completing their studies, and they can see hope in this village. With the support of the state, the railway was built, and it felt that everything was going in a good direction.

When the road was built and connected to the outside world, I realized that the times were really developing rapidly. There is less of this part of our house, and things are more modern. Although I feel that the neighborhood relationship is not as good as before, this is also an inevitable trend of social development.

The main opportunity is in tourism, the mountains in my hometown have also been protected, and there are fewer people going up to the mountains to cut wood, because people from the State Forestry Administration come here to watch. More emphasis on sustainability.

The excavation of the Qinghai-Tibet Railway is a miracle, and 500,000 people come to La by train every year.

Sa. This miracle is the result of the hard work and wisdom of the builders to complete this huge project, which also makes it a lot more convenient for tourists.

The 1,142-kilometre-long Qinghai-Tibet Railway, with 10 tunnels and 675 bridges along the way, crosses the Qinghai-Tibet Plateau, the world's harshest natural environment, which is extremely cold at high altitude. The thin air is potentially lethal, and the frozen ground is so unstable that the world thinks it is impossible to build a railway on the world's highest plateau. It's not the longest railway, but it's undoubtedly the most difficult to build.

It's an architectural spectacle, how did China accomplish it? It's also up to clever builders.

In the face of difficulties again and again, the fighting spirit of the road construction army is high. It passes through the permafrost, which is extremely hard in winter and unusually soft in summer. A quarter of the Northern Hemisphere is covered by permafrost, which is sometimes more than 1,500 meters thick.

It is rock-solid in winter, but in the summer the surface melts and settles, and when winter comes again, it freezes again, increases in size and raises the ground, and the railroad built in such an unstable area will undoubtedly be deformed. However, the builders were not afraid of hardships and used their wisdom to overcome this "roadblock".

The miracle of the Qinghai-Tibet Railway is the crystallization of the hard work and wisdom of the builders, who are not afraid of hardship, perseverance, and tenacious perseverance to complete this huge project. We owe a debt of gratitude to these builders for building this miracle.

After the long-term high-speed impact of the train, the ballast will be fragmented, and even pulverization phenomenon will be produced, and after the pulverized ballast is filled into the gap, the track bed will be compacted and the elasticity will be reduced (reference: the track bed disease (beddisease) acts repeatedly with the train load, and the abnormal deformation of the gravel track bed mainly includes the permanent deformation of the track bed, the dirty track bed, the pulverization of the track bed, the collapse of the track ballast, the slurry of the track bed and the stiffness of the track bed, etc.). ）

Therefore, every once in a while, the public works section has to start the road for tamping operation, and the cleaning of the track bed railway also needs to be maintained.

> and "Harmony" has specific rules and terms, and I will briefly say it.

On the single-track railway, there are two situations of meeting the car and giving the car, there is generally no train grade problem when the car is meeting, the train of the advanced road should avoid the train that enters the road after the train, and after the train enters the starting line, then the car will be the first and then give way; When giving way, there is a problem of grade, low-grade trains should give way to high-grade trains, ordinary trains should give way to special trains, in the category of passenger trains, temporary passenger cars have the lowest grade, and small runs should give way to trains with large intersections.

On the double-track railway, there is no problem of waiting for the car to be avoided, only the problem of giving way to the car, that is, on the double-track railway, it is divided into up and down, and all the up or down trains are running in the same direction on the same line, so there is only the problem of giving way, and when giving way, it is also the principle of giving way to low-grade trains to high-grade trains and ordinary trains to special trains.
