198 1 year, a mountain torrent caused the biggest traffic accident of China railway. What was the result?

China has made great progress in transportation, and its achievements have attracted worldwide attention. With the labor wisdom of the people of China, one traffic miracle after another is presented to us. We are fearless, whether it is the plateau, the hillside or the mountains, but there are also blood and tears behind the laughter. Behind many successes is the hard work of the working people.

As an important part of transportation, railway construction has countless experiences and lessons. In the process of building a railway, in order to find the most suitable method, workers need to keep exploring, and of course accidents will inevitably occur. 198 1 year, a bridge accident occurred in lizida, Chengdu-Kunming line, killing 275 people, which was the most serious railway accident in Chinese history.

The accident 39 years ago was heartbreaking. At that time, the staff also conducted a systematic investigation and experienced a comprehensive comparison of various factors, and finally found the culprit.

The sudden tragedy killed many people and shocked the whole country.

In the early morning of July 9th, chengdu-kunming railway got on, and the 442 express train left grip for Chengdu. At that time, it was slowly entering Niger station, followed by a period of stop. Of course, this is not only to let passengers get on and off here, but also an important purpose is to let the oncoming 2 1 1 train pass first, because only when this train passes safely can the 442 train leave the station.

The next stop after the 442 train leaves nigri Station safely is Wushe Station. The personnel on duty at nigri Station need to contact the Wushe River with optical cable signals and tell the other party that the 442 train is running in this area. But I suddenly lost contact at that time, as if something special had happened in front! However, the staff of the 442 car thought about it. A minute ago, the car of 22 1 just passed by. What will happen in such a short time?

198 1, the train is not equipped with wireless communication equipment, so it is impossible to know the situation of the 442 train accidents ahead. In this way, the train kept moving forward in confusion and worry. There is a tunnel called Grandma Bao on this road, and its exit is near Lizi Yida Bridge, but the driver Wang Mingru, who was about to get out of the tunnel, found that the reflection of the tunnel was gone, indicating that there was no railroad track ahead and the bridge was broken.

At this critical moment, the driver hurriedly pulled down the emergency brake, but the train rushed out. The second locomotive, including the locomotive head, 12 mail car, 13 baggage car, and the bus No.9 to 1 1, all fell from mid-air. Fortunately, all the passengers on the 7 passenger cars behind the train and the 1 dining car were rescued.

Finally, the tragedy slowly ended, but 275 people were still killed or missing. The accident shocked the people of China.

Multi-party investigation revealed the truth.

Now we are very familiar with the whole process of the incident, but there are still many people who have doubts: Why did the railway suddenly collapse a few minutes ago when it was still safe? What kind of power will cause such consequences? In order to know the truth, the investigation team entered Lizida.

Some people speculate that it may be man-made, such as blasting with explosives. However, the investigation team does not think so. After all, no useful clues were found at the scene of the accident, and the explosive that can blow up the whole bridge must be very powerful and huge, so it is impossible to transport it by car or drop it by air.

In the process of continuous exploration, the investigation team suddenly discovered an important fact. There are many big stones in Liziyi gully, but they didn't exist before, so experts suspect that these stones may be brought by mudslides. Unfortunately, it didn't rain much on the day of the accident, so in theory, there would be no debris flow.

Later, they expanded the scope of investigation and finally found out the truth. It turned out that on that day, the source of this ditch suddenly rained heavily, which led to flash floods on the mountain at an altitude of more than 4,000 meters, thus triggering a rare large-scale mudslide. It crossed the hillside, brought a lot of stones and sediment, and finally formed more than 400 tons of stones, and finally washed away the bridge.

At this point, the truth of the matter finally came out and the deceased was confessed. Having learned this lesson, China has gained more experience in railway.

Today is not what it used to be, and railway construction has a long way to go.

It's been 39 years since then, and now it's already desolate. When we came to Lizi Yida Bridge, we could see that there were only some broken piers and a pile of rubble, and there were no rails and sleepers in Baomawei Tunnel. If there weren't some traffic signs on the wall, maybe we wouldn't remember that the train had passed here.

No matter how big the disaster is, it will eventually become a thing of the past. In order not to make it just an accident, we should learn from it and work hard. Now the new Lizida Tunnel has been rebuilt, and the Cheng Kun route will pass through the mountain at the bottom of the ditch, which will not be affected by mudslides, which means that such disasters will not happen again.

Many railway lines have many similar things, and the current improvement measures are far from enough. In order to avoid such a tragedy, we should often reflect on ourselves, deeply study various natural disasters, and rebuild and build railways accordingly.

Chengdu-kunming railway in the new period is the best example. After continuous improvement and transformation, chengdu-kunming railway has become an important national railway trunk line.

summary

The lofty moral significance of labor lies in whether a person can reflect his wisdom, skills, selfless love for his career and his willingness to pass on his experience to his comrades in arms in the material achievements of labor. Suhomlinski

Miracles can always appear in the vast land of our country, and behind these miracles is the accumulation of labor experience unimaginable to ordinary people. When faced with the blank or incomplete operation of railway technology, our ancestors wrote page after page of industry resumes with their lives and blood, laying the foundation for today's brilliant achievements.

Labor is noble, and the labor that struggles for the national cause and even gives his life has made great contributions. Although nearly 30 years have passed, the people of China will never forget those people.

The lessons of the past are the lessons of the future. Future workers will continue to digest the experience of predecessors, strive to innovate, reduce the accident rate and better protect the personal safety of workers. This is a respect for ancestors, and it is also a respect for grassroots workers. Such "volunteering" is the great significance of labor.
