A little story that happened when Zhan Tianyou was building the Beijing Zhangjiakou Railway! Urgent!

At that time, China had already begun to build railways, but they were all paid for by foreigners. Zhan Tianyou saw that the Chinese could not build their own railways on their own land, and the railways built by foreigners were used to sell foreign goods and plundered products, Zhan Tianyou sighed!

Before Zhan Tianyou went north, he specially returned to his hometown to visit his parents. His relatives were happy that he had a new job in the north.

When passing through Shanghai, Zhan Tianyou went to Wusong to pay tribute to the remains of the Songhu Railway. It was the first railway built by Britain in China. Fourteen years ago, when the traffic was opened, she shocked the ignorant and stubborn Queen Mother Xi, she thought that this behemoth locomotive, spewing smoke and spitting smoke, dragging the long dragon rumbling and running, "destroying the feng shui of the Qing Dynasty", so she ordered to buy it back from the British with 180,000 taels, dismantle all the locomotives and rails, transport them to Taiwan by steamer, and sink into Dagou Lake.

How stupid, how abominable!

After Zhan Tianyou arrived at the China Railway Company, he saw that the company was nominally a "government-supervised business-run" company and a Chinese company, but in fact it was controlled by British imperialism. Chinese businessmen proposed that China's railways "should be built from the Chinese rather than from the foreigners; It is better to repair from the government than from the people", but it is not been. Due to the corruption of the Qing Dynasty and the poverty of the country, the railways in China at that time were all built by foreigners, loaned from foreign imperialists, and led by foreign engineers.

Zhan Tianyou was indignant in his heart, and he firmly believed that sooner or later China's railways would be built by the Chinese themselves.

While building the railway, several of his co-workers accidentally fell off a cliff, and his daughter was killed. During the construction, several foreigners were sent to disguise themselves as hunters and seize the opportunity to laugh at Zhan Tianyou. [I just learned this lesson, and the teacher's PPT put these small stories, there should be more than these, I just briefly give a list. 】

Difficulties encountered: obstruction by foreign countries, lack of technical personnel, arduous tunnel engineering, and large railway slopes;

He is not afraid of ridicule, not afraid of danger, difficulty, accurate survey of the line, the use of both ends at the same time to the middle of the chiseling, the use of the middle sinking method, the first soldier to rush to work, the design of the "human" herringbone line.

Experience Zhan Tianyou's intelligence, bravery, perseverance and patriotism.

On September 24, 1909, the Beijing-Zhangjiakou Railway was completed two years ahead of schedule, and the cost of the project was only 1.5 estimated by foreigners. The completion of this railway connected Beijing with the northwest, and broke the dream of Britain and Tsarist Russia to seize the right to build the railway. At the same time, it has also greatly increased China's confidence in building its own railways.

At the end of the Qing Dynasty, imperialism frantically fought for the right to build railways in China. The strategically important Beijing-Zhangjiakou Railway (Beijing-Zhangjiakou) was the target of fierce competition between Britain and Tsarist Russia. Britain and Russia each made threats to the Qing Dynasty:

If China can't build the Beijing-Zhangjiakou railway with its own money and engineers, it will have to be built by them. Under this pressure, in 1905 Zhan Tianbo undertook the task of building the Beijing-Zhangjiakou Railway, which was the first arduous project built by the Chinese with their own money and engineers. After accepting the task, he overcame all difficulties and achieved a lot.

In particular, he fought side by side with the workers and opened up the world-famous Badaling Tunnel with a length of 1,091 meters, which is even more praised.

Zhan Tianyou is an expert in railway engineering in China, graduated from Yale University in the United States, and from 1905 to 1909 he presided over the construction of China's first self-built railway, the Beijing-Zhangjiakou Railway. In the construction, the "human" herringbone line was used according to local conditions to reduce the number of projects, and the "shaft construction method" was used to excavate the tunnel.

Obstructed by foreign countries, lacking technical personnel He is not afraid of ridicule and danger.

Juyongguan mountain is high, the rock layer is thick, Zhan Tianyou decided to adopt the method of chiseling from both ends to the middle at the same time, the Badaling Tunnel is more than 1,100 meters long, and it is three times as long as the Juyongguan Tunnel. He consulted with the old workers and decided to use the central shaft sinking method. A shaft was drilled from the top of the hill down, and then excavated at both ends, and both ends were also constructed at the same time, shortening the construction period by half.

The railway passes near the Qinglong Bridge, and the slope is particularly large, and Zhan Tianyou has designed a "human" herringbone line along the mountain. When the northbound train arrives at the south exit, it uses two locomotives, one pulled in front and one pushed in the back. After crossing the Qinglong Bridge, the train goes northeast, and the fork of the "human" herringbone line is reversed, the locomotive that was originally pushed pulled, and the locomotive that was originally pulled pushed, so that the train turned to the northwest and moved forward.

Landlord, I'm here to tell you a wise quote that I invented.

The ridicule of imperialism is faced bravely.
