Who was the first engineer in China?

Zhan Tianyou. Zhan Tianyou is a famous patriotic engineer in China. Under his auspices, the railway from Beijing to Zhangjiakou was successfully built for the first time. This is a railway trunk line designed and built by China engineers and technicians. The railway from Beijing to Zhangjiakou is 200 kilometers long. It is the traffic artery connecting the west and northwest of China. At that time, just after the Qing government put forward the construction plan, some imperialist countries came out to obstruct it, all vying for the right to build this railway, and trying to further control China's northern imperialism, and no one would let anyone. The dispute has not been settled for a long time. They finally put forward a condition that if the Qing government built the railway with its own engineers, the railway could not be started. Finally, they had to ask them for help. The imperialists are completely 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 caused a national sensation. Everyone says we can fight this time. The imperialists think this is a joke. A foreign newspaper said contemptuously that engineers who can build a railway north of Nankou have not yet been born. It turns out that all the way from Juyongguan to Badaling, north of Nankou, are mountains, deep streams and cliffs. They think that famous foreign engineers dare not try such a difficult project easily, and as for China people, it is impossible to paste it anyway. Zhan Tianyou is not afraid of difficulties and ridicule. He resolutely accepted the task and immediately began to detect where the route should be cut, where to bridge, where to level the steep slope, and where to reduce the curvature, all of which should be carefully calculated through detection. Zhan Tianyou often told the staff that our work should be accurate first, and we should not be a little sloppy. Probably, this statement should not come from the mouth of engineers. He personally took students and workers, carried benchmarks and theodolite, and customized maps on steep cliffs. Outside, the wind has been whistling and the yellow sand is all over the sky. If you are not careful, you may fall into the ravine. No matter how poor Joe's conditions are, Zhan Tianyou always insists on working in the fields. Crossing mountains and mountains during the day and drawing and calculating under oil lamps at night. In order to find a suitable route, he often asks local farmers. When encountering difficulties, he always thinks that this is the first railway built by China people themselves, and it must be built, otherwise it will not only make foreigners laugh. It will also make engineers in China lose confidence. Railways have to dig tunnels to cross many mountains, among which Juyongguan and Badaling tunnels are the most dangerous. Juyongguan Mountain is high and the rock stratum is thick, so Zhan Tianyou decided to dig 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. Badaling Tunnel is three times as long as Juyongguan Tunnel. He discussed with the old workers and decided to adopt the intermediate sinking method. First, a big tree, gold and a small shaft were dug from the top of the mountain, then both ends were dug, and both ends outside were also constructed at the same time, which shortened 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 route along the locomotives, and two locomotives were used for the northbound train when it reached the south exit. One pulls the front and the other pushes the Qinglong Bridge at the back. The train turned upside down after passing through the herringbone socket in the northeast. The original locomotive pulled the original flint and pushed the train to the northwest, so it was much easier for the train to climb the mountain. The Beijing-Zhangjiakou Railway was completed in less than four years, two years ahead of schedule, which gave a powerful counterattack to the imperialists who despised China. Today, we went to Badaling by train. You can see a bronze statue at Qinglong Bridge Station, which is the bronze statue of God Bless.
