What kind of animal was the raider on the workers during the construction of the Qinghai Tibet Railw

Tibetan antelope, the longest "bridge instead of road" bridge on the Tibetan railway line, is also the key control project of the construction of the entire Qinghai-Tibet railway Gela section. The most important purpose is to protect the wildlife environment so that wild animals can move freely under the bridge.

The construction units along the line are instructed to carry out a comprehensive clean-up of the construction site of the animal passage.

During the wildlife migration season from June to August every year, the construction of various sections of the Qinghai-Tibet Railway even costs millions of yuan per day.

Stoppage work to wait for wildlife to pass through the construction area naturally, and there are countless stories of construction workers rescuing wild animals.

For alpine montane fauna, it is mainly in the form of passages passing above tunnels; For the alpine steppe meadow fauna, it mainly takes the form of passages passing under bridges and gentle slopes of the roadbed.

I think it's the local wildlife that thinks their homes have been destroyed, so they raid the workers.

In August this year, in order to ensure the smooth return of the Tibetan antelope that gave birth from the south to the north of Hoh Xili a month ago, the Qinghai-Tibet Railway Construction General Headquarters required all construction units along the line to stop work again to make way, and instructed all construction units along the line to carry out a comprehensive clean-up of the animal passage construction site, control the construction vehicles, prohibit honking, and take the initiative to get in touch with the local protection station to guide the Tibetan antelope to migrate through the animal passage.

I think it's probably the kind of animal with a ferocious temperament, and I feel that my territory has been violated.

It is normal for us to have a guest animal as the master, and the guest to give way to the master.

With all due respect, there are some things you still don't know, this world is not so simple, and there are things that are indeed mysterious, but don't delve into them.

Do you mean the humanoid creature that takes the workers and eats people?

Three matches.

In July 1976, Zhang Luxin, Li Lie and a man nicknamed Chen Dabeard went to the area of the Qiqu River to investigate. A blizzard suddenly struck and darkened the sky, and they lost their way.

The blizzard stopped, the clouds did not disperse, and they did not know what to do from east to west, north to south. Realizing that they were going farther and farther away, the more dangerous they became, and finally they had to sit helplessly in a col and wait for their comrades to come to their rescue. The day passed, the night came, the night sent away, the day came again, and in the long day, they waited for the long night ......

Zhang Luxin usually likes to eat sugar, and the 3 pieces of candy in his pocket are the only food for the three of them.

In the base camp, Cheng Guodong and others waited for two days to see Zhang Luxin return, and had a premonition that something had happened to them, so they hurriedly brought people out to look for them, and Cheng Guodong was so anxious that he cried. In order to find Zhang Luxin, he decided to divide his troops into three ways, carrying torches, against the night, in the empty wasteland, they shouted Zhang Luxin's name with tears in their eyes.

In the dark night, Zhang Luxin and the three of them were hungry and exhausted, and they heard the shouts of their colleagues in the distance, but they were unable to respond to them. Li Lie asked Zhang Luxin weakly"What to do? Are we waiting for death? "

Chen Beard said"There are also three matches in the matchbox, and the matches are used to send a signal to the comrades. "Zhang Luxin agreed. Unexpectedly, the first match was blown out by the wind.

Chen Dabeard hurriedly wanted to draw a second one, but was stopped by Zhang Luxin, Zhang Luxin said:"Don't you still have a paper cigarette case? Tear the paper cigarette case into 3 strips, light the strips with matches, and burn them one after the other, and the comrades may find us.

Chen Dabeard did so, and finally sent a signal of life.

The glimmer of light in the dark night was discovered by Cheng Guodong, so he rescued a star of science and technology from the death line for the future Qinghai-Tibet Railway.

In the 70s of the last century, there were more than 100 people engaged in the study of the permafrost of the Qinghai-Tibet Railway. After the 80s, many experts, those who were transferred, those who changed careers, and those who retired, only a few people such as Zhang Luxin persevered and continued to stick to the ...... with firm faith

The 10th Division of the Railway Corps had a company commander named Deng Guangji, and in order to build the Qinghai-Tibet Railway, he took Du to the plateau with illness. Later, he contracted leukemia in Gaozhiyuan. When rescuing him in the hospital in Jiadao Township, he left a will to his relatives and comrades-in-arms:

If I die and bury my ashes on the Qinghai-Tibet Plateau, I did not build the railroad during my lifetime, and I will see the railroad built on the roof of the world after I die.

In order to achieve the "two centenary" goals.

The main difficulties are three difficulties encountered in the excavation of the wind volcano tunnel: first, the permafrost; the second is bad weather; The third is extreme hypoxia.

In the process of overcoming these difficulties, there is a tenacious spirit in the builders. This spirit is manifested in the ability to endure hardships, endure hardships, and fight; With a scientific attitude and the spirit of innovation, we are fighting on the construction site. They opened roads in the mountains and built bridges in the water.

In front of the "railway soldiers", there is no mountain of flames that cannot be broken. They are not afraid of the danger of their lives, and overcome the difficulties brought about by the harsh climate and natural conditions such as high cold, low pressure, lack of oxygen, wind and snow, thunder and lightning, and sandstorms; With their scientific and innovative spirit, they solved the world-class problems of permafrost and extreme hypoxia.

One is the lack of oxygen in the high mountains.

The second is the problem of permafrost.

The third is environmental protection.

Fourth, it does not affect animal migration.

Fifth, the terrain is complex.

1: In order to solve the problem that the lack of oxygen affects the work of the staff and makes the project slow, the engineering personnel brought the large oxygen generator to the plateau to provide sufficient oxygen for the engineering personnel who built the tunnel, and the oxygen content in the tunnel was only equivalent to about 1000 meters above sea level, which greatly accelerated the progress of the project.

Second: the problem of permafrost is the largest permafrost research base in China and even the world, in order to overcome the permafrost problem, since the start of construction of the Qinghai-Tibet Railway, the Ministry of Railways attaches great importance to the Qinghai-Tibet Railway permafrost research problem, has arranged hundreds of millions of yuan of scientific research funds for permafrost research, and organized a number of experts from scientific research institutions to tackle key problems in the experimental section of the Qinghai-Tibet Railway five permafrost engineering experiments, and obtained a large number of scientific research data and scientific research results. The frozen soil research of the Qinghai-Tibet Railway draws on the frozen soil construction experience of large-scale projects such as the Qinghai-Tibet Highway, the Qinghai-Tibet Oil Pipeline, and the Lansila Optical Cable, and draws on the frozen soil research results of Russia, Canada, Northern Europe and other countries.

At present, China's scientists have taken measures such as replacing the road with bridges, ventilated roadbed with stone sheets, ventilation pipe subgrades, gravel and stone slope protection, hot rods, thermal insulation boards, and comprehensive anti-drainage systems, and have made significant progress in tackling frozen soil, and the Qinghai-Tibet Railway has become the world's largest frozen soil research base in China, and the engineers have made thousands of cement piles buried under the groundbreaking on the plateau, providing sufficient support for the operation of the railway.

Three: in order to protect the blue sky of the plateau, the clear lake, rare wild animals, the Qinghai-Tibet railway only environmental protection investment of more than 2 billion yuan, accounting for 8 of the total investment of the project, is currently China's largest environmental protection investment in the railway construction project, and in the national engineering construction for the first time to introduce environmental protection supervision, the first time with the local environmental protection department to sign the environmental protection responsibility letter.

Fourth: For the first time, the staff opened up a migration channel for wild animals, and the Qingshui River Bridge located in the Hoh Xil National Nature Reserve was specially built by the Qinghai-Tibet Railway for the migration of Tibetan antelopes and other wild animals.

5. In order to solve the terrain problem, the engineers built the world's highest railway station - Tanggula Station, which is also the highest railway station in the world.

The first high bridge of the Qinghai-Tibet Railway - Sancha River Bridge.

The world's longest plateau permafrost tunnel - Kunlun Mountain Tunnel.

The world's highest highland permafrost tunnel, the Wind Volcano Tunnel.

China's largest plateau railway paving base - Qinghai-Tibet Railway Nanshankou paving base.

The longest "bridge instead of road" project on the Qinghai-Tibet Railway Line - Qingshui River Bridge.

Geely Emhaus is particularly good 1

The highest altitude.

The line is the longest. Lack of oxygen in the mountains.

The tundra is complex.

Inclement weather.

Hypoxia in the mountains Permafrost Protecting the environment Does not affect animal migration The altitude is the highest.

The line is the longest.

"Every Shovel of Soil Must Be Legal" is a story that happened during the construction of the Lhasa Railway!

In the process of construction of the Qinghai-Tibet Railway, every spade must comply with the statutory norms, and the project is not allowed to start without environmental protection measures. This strict environmental management measure has promoted the development of environmental protection work in the construction of the Qinghai-Tibet Railway.

The construction of the railway on the plateau is strictly controlled, and the length and width of the road must be drawn with a red line, and it is not allowed to cross the thunder pond, and violators will be severely punished. In many areas of the Tibetan Plateau, the terrain is flat, and at the beginning, drivers see a flat river, and sometimes do not follow the boundaries of the car, destroying the environment, and the ensuing punishment is very severe.

Once, a driver of the 12th Bureau of China Railway detoured about 10 meters out of the road when transporting materials at the construction site, and after the bureau headquarters knew, in addition to punishing the driver, he also fined 100,000 yuan to the project department where the driver was located, and the project manager had to take people to restore the grassland.

The construction of the project will inevitably occupy land. In order to maximize the protection of the grassland, during the construction, the builders invented the turf replanting technology. When the construction had to occupy the land, the workers first dug up the turf piece by piece and placed it in other places, and applied water for maintenance.

When the work was completed, they replanted the turf piece by piece back to the original land.

In order to protect the environment, the Qinghai-Tibet Railway Construction Headquarters also cooperated with the Institute of Zoology and Zoology of the Chinese Academy of Sciences, the Academy of Forestry and other units to establish three grass planting experimental sites above 4,000 meters above sea level in Tuotuohe, Amdo and Dangxiong, which is unprecedented in the history of plant research in China. At present, gratifying progress has been made in the grass planting experiment, and the growth of green grass is gratifying.

You can refer to the MV of Han Hong's "Heavenly Road", there are many details worth paying attention to.

There is also an interview with the Qinghai-Tibet Railway, which was broadcast on ** Taiwan.

This is the text of the second volume of the fifth grade, in you say.
