Zhan Tianyou is an outstanding engineer in our country. 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, the 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 finally put forward a condition: if the Qing government used its own engineers to build the railway, it would not ask again. They thought that with such a threat, the railway could not be started, and finally they had to ask them for help. The imperialists got it all wrong. China had its own engineers at that time, and Zhan Tianyou was one of them.
1905, the Qing government appointed Zhan Tianyou as the chief engineer to build the Beijing-Zhangjiakou railway. When the news came out, it sensationalized the whole country. Everyone says we can 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 (YN ɡ) to Badaling, all the way is a cliff with high mountains and deep streams. In their view, famous foreign engineers dare not try such an arduous project easily, and China people 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, saying, "Our work must be accurate first, and we can't be a little sloppy. The expressions' probably' and' almost' should not come from engineers. " He personally took students and workers, carried benchmarks, and carried theodolite to fix points and draw on the cliff. 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 some foreigners laugh, but also make China engineers lose confidence.
The railway has to pass through many high mountains, so it is necessary to dig tunnels, of which Juyongguan and Badaling tunnels are the most difficult projects. Juyongguan Mountain is high and the rock stratum is thick, so Zhan Tianyou decided to adopt the method of simultaneous excavation from both ends to the middle. 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, two shafts were drilled down from the top of the mountain, and then dug at both ends. At the same time, the outer ends were constructed, and the construction period was shortened 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 completed in less than four years, 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.
Zhan Tianyou's appreciation of the text "Zhan Tianyou" is based on the name of Zhan Tianyou, an outstanding patriotic engineer and railway engineering expert in China, and focuses on one of the most important events in his life, that is, the construction of the first Beijing-Zhangjiakou railway designed and constructed entirely by Chinese engineers and technicians. Starting with the background and difficult geographical environment of the construction of Beijing-Zhangjiang Railway, it shows that the construction of Beijing-Zhangjiang Railway has experienced many difficulties. Zhan Tianyou led China engineers and technicians to overcome many difficulties and completed the Beijing-Zhangjiakou Railway ahead of schedule. He praised Zhan Tianyou's patriotic thought and outstanding talent, and also showed the wisdom and strength of the people of China. Under the auspices of Zhan Tianyou, the Beijing-Zhangjiakou Railway was completed two years ahead of schedule, which effectively countered the imperialism's contempt for the people of China and safeguarded the dignity of the motherland.
