Zhan Tianyou, whose real name is as soon as possible, is from Wuyuan, Jiangxi. 186 1 year (the 11th year of Qing Xianfeng) was born in an ordinary family of tea merchants. When I was a child, Zhan Tianyou was very interested in machines, and often made various machine models with the children in the neighborhood. Sometimes, he will secretly take apart the bells at home, fiddle with the components inside and ask questions that even adults can't answer. From 65438 to 0872, Zhan Tianyou, who was only 12 years old, went to Hongkong to sign up for the preparatory class for young children going abroad organized by the Qing government. After passing the exam, my father drew a note on a certificate of going abroad, which said, "If there is illness, life and death, everyone will live in peace." After that, he left his parents and came to the United States to study with the ideal of learning western "skills". After Zhan Tianyou won the first battle, he immediately encountered a more severe test. 1905, the Qing government decided to build the first railway in China-Jing-Zhang Railway. Both Britain and China wanted to intervene, but their attempts failed because of the strong opposition of the Russian people. The British and Russian envoys said in a threatening tone: "If the Beijing-Zhangjiakou Railway was built by Russian engineers themselves, it has nothing to do with Britain and Russia." They think that, in this way, it is impossible to build a railway in China. At this critical moment, Zhan Tianyou accepted this arduous task without hesitation and was solely responsible for the construction of the Beijing-Zhangjiakou Railway. News came that some imperialists and British newspapers sarcastically said, "The engineer who can build this railway in China has not been born in the womb! China people want to build railways without foreigners, even if it is not a dream, it will take at least 50 years. " They even attacked Zhan Tianyou, the general manager and chief engineer, for being "arrogant" and "overreaching". Under pressure, Zhan Tianyou insisted on not appointing foreign engineers, and said: "China is vast and rich in resources, and I feel ashamed to rely on outsiders all the way to work!" "China has awakened, and China people will use their own engineers and their own money to build railways."
1In August, 905, the Beijing-Zhangjiakou Railway was officially started, and intense exploration and route selection began. Zhan Tianyou ran around the rugged mountain day and night with the measuring team and instruments on his back. One evening, the fierce northwest wind roared in Badaling area, whizzing past with dust, which made people unable to open their eyes. The survey team finished the work in a hurry, filled in the survey figures and climbed down from the rock wall. Zhan Tianyou took the notebook, looked at the figures and asked doubtfully, "Is the data accurate?" ? "Almost," replied the surveyor. Zhan Tianyou said seriously: "The first requirement of technology is accuracy, and there can be no ambiguity or rashness. Statements like' probably' and' almost' should not come from engineers. " Then, he picked up the instrument, braved the wind and sand, and labored to climb to the rock wall again, carefully retest and corrected a mistake. When he came down, his lips were purple with cold.
Soon, exploration and construction entered the most difficult stage. At Badaling and Qinglong Bridge, there are overlapping mountains and steep walls hanging rocks, and four tunnels will be opened, the longest of which is more than 1000 meters. After accurate calculation, Zhan Tianyou decided to adopt the method of sectional construction: simultaneously drilling from the north and south ends of the mountain, opening a large well in the middle of the mountain, and then drilling from the north and south ends in the well. This not only ensures the construction quality, but also speeds up the project progress. When digging a hole, I dug a lot of stones by hand and picked out the spewing spring water one by one. Zhan Tianyou, as the chief engineer, has no shelf. He digs stones and carries water with the workers, and his face is covered with mud and sweat. He also encouraged everyone to say, "The Beijing-Zhangjiakou Railway is the first railway that we built with our own people and our own money. The eyes of the whole world are watching us, and we must succeed! " "No matter success or failure, it is definitely not our own success or failure, but the success or failure of our country!"
In order to overcome the difficulty of driving on steep slopes and ensure the train to climb up Badaling safely, Zhan Tianyou creatively used the principle of "turn-back line" to design a herringbone line on the steep Qinglong Bridge section in mountainous areas, which reduced the tunnel excavation and slope. When the train arrives here, it will cooperate with two high-powered locomotives to push and pull to ensure the safety of the train uphill.
Zhan Tianyou once put forward three requirements for the whole project: "less money, good quality and quick completion". After several struggles by workers, the Beijing-Zhangjiakou Railway was finally opened to traffic in September 1909. It was originally planned to be completed in six years, but it was completed four years ahead of schedule, and the project cost was only one-fifth of that estimated by foreigners. Some European and American engineers paid tribute to Zhan Tianyou after visiting by bus. But Zhan Tianyou said modestly: "This is the strength of more than 10,000 employees of Beijing-Zhangjiakou Railway, not my personal credit. Glory should belong to everyone. "
After the Beijing-Zhangjiakou Railway was completed, Zhan Tianyou succeeded as the supervisor and chief engineer of the Guangdong-Han Railway. At this time, the United States decided to grant him a doctorate in engineering and asked him to go to the United States to attend the conferring ceremony in person. He gave up this honor in order to devote himself to the railway construction of the motherland.
After the Revolution of 1911, in order to revitalize the railway industry, Zhan Tianyou and his colleagues established the China Engineering Society, and was promoted to president. During this period, he devoted a lot of efforts to the training of young engineers and technicians. In addition to setting an example, he also encouraged young people to "study hard for invention" and asked them not to "favor one over the other, and not to fish for fame". Take others with sincerity, not yourself as a mirror. "
Zhan Tianyou has been engaged in the railway industry for more than 30 years. At that time, almost every railway in China had different degrees of relationship. Old age breaks down from overwork 19 19. Comrade Zhou Enlai once spoke highly of Zhan Tianyou's achievements, calling him "the glory of the people of China".

Zhan Tianyou Information-Primary School Texts-Zhan Tianyou
Zhan Tianyou is an outstanding patriotic engineer in China. Under his auspices, the railway from Beijing to Zhangjiakou was successfully built for the first time. This is the first railway trunk line designed and built entirely by China engineers and technicians.
The railway from Beijing to Zhangjiakou is 200 kilometers long, which is the traffic artery connecting North China and Northwest China. At that time, as soon as the Qing government put forward the construction plan, some imperialist countries came out to obstruct it. They all want to fight for the right to build this railway and further control the northern part of our country. The imperialists refused to let people go, and the matter dragged on for a long time They made a condition: if the Qing government used its own engineers to build the railway, they would stop asking. They thought that the railway could not be started because of this threat, and finally they had to turn to them for help. The imperialists got it all wrong. China had his own engineer at that time. Zhan Tianyou is one of them.
1905, the Qing government appointed Zhan Tianyou as the chief engineer to build the Beijing-Zhangjiakou railway. As soon as the news came out, it caused a sensation all over the country, and everyone said that they could win a sigh of relief this time. The imperialists think this is a joke. A foreign newspaper said contemptuously, "China engineers who can build a railway north of Nankou have not yet been born." It turns out that from the south exit to the north through Juyongguan to Badaling, there are mountains, deep streams and cliffs all the way. They think that famous foreign engineers dare not try such a difficult project easily, and as for China people, they can't finish it anyway.
Zhan Tianyou, not afraid of difficulties and ridicule, resolutely accepted the task and immediately began to survey the line. Where to cut mountains, where to build bridges, where to level steep slopes and where to reduce curvature all need to be investigated and carefully calculated. Zhan Tianyou often encourages the staff to say: "Our work must be accurate first, and we can't be a little sloppy." "Probably" and "almost" should not come from engineers. "He personally with students and workers, carrying benchmarks, carrying theodolite, fixed-point on the cliff, surveying and mapping. The Great Wall is often windy and dusty, and if you are not careful, you are in danger of falling into a deep valley. No matter how bad the conditions are, Zhan Tianyou always insists on working in the wild. During the day, he climbed mountains and surveyed routes; In the evening, he paints and calculates under the oil lamp. In order to find a suitable route, he often asks local farmers. When encountering difficulties, he always thought: This is the first railway built by China people themselves, and it must be built; Otherwise, it will not only make foreigners laugh, but also make engineers in China lose confidence.
The railway has to pass through many high mountains, so it is necessary to dig tunnels, among which Juyongguan and Badaling tunnels are the most arduous projects. Juyongguan Mountain is high and the rock stratum is thick, so Zhan decided to adopt the method of excavating from both ends to the middle at the same time. The spring water at the top of the mountain seeped downward, and the tunnel was full of mud. There was no water pump on the construction site, so Zhan Tianyou took the lead in carrying buckets to drain water. He often eats and lives with the workers and never leaves the construction site. Badaling Tunnel is over 1 100 meters long, which is three times as long as Juyongguan Tunnel. He discussed with the old workers and decided to adopt the intermediate sinking method. First, drill a shaft from the top of the mountain, then dig at both ends, and the outer end will be constructed at the same time, which shortens the construction period by half.
The railway passes near Qinglong Bridge, with a particularly steep slope. How can a train climb such a steep slope? Zhan Tianyou designed a herringbone line along the mountain. When the northbound train arrives at the south exit, two locomotives are used, one is pulling in front and the other is pushing back. After crossing the Qinglong Bridge, the train went northeast, crossed the fork of the herringbone line and turned upside down. The original locomotive was pulled and pushed, making the train turn to the northwest. In this way, it is much easier for the train to go up the hill.
The Beijing-Zhangjiakou Railway was built less than four years ago, two years ahead of schedule. This incident gave a powerful counterattack to the imperialists who despised China. Today we go to Badaling by train and pass Qinglong Bridge Station. We can see a bronze statue, which is the statue of Zhan Tianyou. Many foreign guests visiting China are amazed at the great project left by Zhan Tianyou.
