What difficulties have been overcome during the construction of the Beijing Zhangjiakou Railway?

Overcoming the lack of funds, the poor passing capacity of the Guangou section of the Beijing-Zhangjiakou Railway, and the shortage of machinery.

In order to overcome the difficulties of driving on steep slopes and ensure the safe climb of the train to Badaling, Zhan Tianyou was ingenious and creatively used the principle of "switchback line" to design a herringbone line in the Qinglong Bridge section with steep slopes, thereby reducing the excavation of the tunnel and reducing the slope. The train drove here, with two high-horsepower locomotives, pulling and pushing, to ensure the safe uphill of the train.

Zhangjiakou is the key point from Beijing to Inner Mongolia, and the passage between the north and the south has always been fought for by the soldiers, so the Beijing-Zhangjiakou Railway has important economic and political value.

The Beijing-Zhangjiakou Railway is the first railway trunk line designed and constructed by the Chinese themselves, which is the glory of the Chinese people and the Chinese engineering and technological circles, and also a victory in the anti-imperialist struggle of the Chinese people in China's modern history. Although the construction of the Beijing-Zhangjiakou Railway by the Chinese themselves was a sad victory under the special historical background at that time, Zhan Tianyou and the Beijing-Zhangjiakou Railway, as well as the national spirit contained in it, became the eternal pride of the Chinese people. Beijing-Zhangjiakou Railway - "The Glory of the Chinese People" Beijing-Zhangjiakou Railway, as a symbol of industrial civilization entering China, its development and changes reflect the annual ring of China's century-old development.

The Beijing-Zhangjiakou Railway is the first railway in China built with Zhan Tianyou as the chief engineer.

Problem description: In what year? Fast, parsing:

In 1905, Zhan Tianyou was assigned to preside over the construction of the Beijing-Zhangjiakou Railway, first as the General Engineering Department and the General Engineering Department, and then as the General Engineering Department and the General Engineering Department. The Beijing-Zhangjiakou Railway is about 200 kilometers long from Beijing to Zhangjiakou and is located on the main road to the northwest. Due to the competition between Britain and Russia for the right to build, the Qing Dynasty decided to build and manage it on its own.

The Beijing-Zhangjiakou Railway passed through the Jundu Mountains, and the project was extremely arduous, and foreigners talked about it, believing that China was unable to complete such a difficult and dangerous project, and they scoffed at Zhan Tianyou. In the face of foreign ridicule, Zhan Tianyou led all the construction staff with a fearless spirit, advanced in the face of difficulties, and worked together to win glory for the country.

At the beginning of construction, there was a shortage of engineering and technical personnel, and Zhan Tianyou led only two graduates of Shanhaiguan Railway School to survey the whole road in detail. Outside the fortress, the wind is often howling, and the sky is full of gray sand. Braving the danger of being driven into a deep valley by a strong wind, Zhan Tianyou and the engineers carried a pole and theodolite on their backs to make a fixed-point map on the cliff.

In search of an ideal route to build, he often rode a small donkey up and down rugged mountain trails. During the day, he crossed the mountains and mountains, and at night he leaned over the drawing and calculation under the foreign oil lamp, and then proposed the construction method, and recruited the only engineering and technical personnel in China to build the road. He set the policy of building this road as soon as possible, so that after the early completion of the road, he could free up his strength to support other provinces to run their own railways.

The most difficult part of the Beijing-Zhangjiakou Railway is the Badaling Tunnel Project. In order to ensure that the railway was completed ahead of schedule, Zhan Tianyou decided to adopt the method of sectional construction. In order to ensure the construction quality of the tunnel, Zhan Tianyou lived on the site, personally checked the details, and personally checked the alignment, positioning, and even the diameter and distance of each blast hole.

The staff was quite infected and hoped that he would take care of his body and rest more, but Zhan Tianyou said seriously: "The eyes of the whole world are looking at us, and we must succeed!" ”

When digging the two tunnels of Juyongguan and Badaling, in the difficult situation of no new mountain opener, pumping machine and ventilator equipment, Zhan Tianyou creatively adopted the construction method of digging at both ends and opening the shaft in the middle, and successfully solved the problem. In his work, he creatively applied the principle of "switchback line" and built a section of "human" herringbone line on the Qinglong Bridge, which has many steep slopes, so that the slope of the line of Guangou was reduced to the following, and the length of the Badaling Tunnel was reduced to half of the design plan.

Zhan Tianyou also according to the characteristics of road construction in the mountainous area, local materials, designed a lot of national characteristics, magnificent stone arch bridges, not only save steel, but also greatly reduce the cost of the project, to achieve his own "less money, first-class, fast completion" three requirements. In 1909, the three sections of the Beijing-Zhangjiakou Railway were completed, which lasted four years, two years ahead of the original plan, and saved more than 280,000 taels of investment, which was regarded as a miracle by foreign engineers at that time.

With a total length of about 200 kilometers, the Beijing-Zhangjiakou Railway starts from Fengtai Liucun in Beijing, and passes through Juyongguan, Badaling, Shacheng and Xuanhua in Hebei to Zhangjiakou. The construction of the Beijing-Zhangjiakou Railway started on September 4, 1905, was completed on August 11, 1909, and opened to traffic on October 2, 2905, shortening the construction time by two years compared with the original schedule. The construction cost was also reduced by $350,000 (some say it was $280,000) compared with the original budget ($7.29 million). The old station building of Beijing North Railway Station was designed by Mr. Zhan Tianyou.
