The Beijing-Zhangjia Railway, built and managed by Zhan Tianyou, connects Fengtai District of Beijing, passes Badaling, Juyongguan, Shacheng and Xuanhua to Zhangjiakou, Hebei, with a total length of about 200 kilometers. /kloc-0 started in September, 905 and was completed in June, 909.

It is the first railway in China designed and put into operation by China people without using foreign capital and personnel. This railway project is arduous. Now it is called beijing-baotou railway, and the former Jingzhang section was the first section of beijing-baotou railway.

2. Zhan Tianyou

Zhan Tianyou (1861April 26, 2009-1965438+April 24, 2009, English name: Jeme Tien Yow), Han nationality, whose word is sincere as soon as possible. ?

Originally from Wuyuan, Huizhou, he was born in Nanhai County, Guangzhou City, Guangdong Province. Its former residence is located at No.42, Bag Lane, Shierfu West Street, Enning Road, Liwan District, Guangzhou. 12 years old studied in the United States, 1878 years old was admitted to the Department of Civil Engineering of Yale University, majoring in railway engineering.

He is an expert in modern railway engineering in China and is known as the first chief railway engineer in China. He is responsible for the construction of Beijing-Zhangjiakou Railway and other projects, and is known as "the father of Chinese railways" and "the father of modern engineering in China".

Extended data:

Zhangjiakou is located outside Juyongguan, northwest of the capital (Beijing), and has been a military and commercial center in northern China since ancient times. Zhan Tianyou was appointed as the chief engineer in the Qing Dynasty, and all the construction and management were completely in the hands of China people, despite the heavy obstruction from Britain and Russia.

In terms of technology, a series of innovative measures have been taken in the Guangou section, such as:

① Using the natural terrain of the east ditch of Qinglong Bridge, adopting zigzag route expansion (see railway alignment technology), combined with the slope of 33.33‰;

(2) Hammer-type compound locomotive is adopted, which is light (only weighs 136 tons) and flexible (it can pass through a small curve radius, see the plane of the railway line);

(3) There are four tunnels in Guan 'gou section, of which Badaling tunnel is the longest, with 109 1 m. When digging this tunnel, the middle shaft method is adopted to speed up the tunnel;

(4) A large number of concrete arch bridges are used, and local materials are used to save labor costs.

Therefore, in a relatively short period of time, the task of building the whole line was successfully completed at the lowest cost. Beijing-Zhangjiakou Railway is a high-quality first-class trunk railway independently built by China people, which has broken the situation that foreigners monopolize the railway construction in China.

In the aspect of route selection design, Zhan Tianyou did not simply adopt the method of improving line standards and increasing engineering quantity, but paid attention to the advanced basic principles of route selection design (see railway route selection). On the one hand, it obeyed the route layout and slope determination, on the other hand, it borrowed locomotives to make up for the shortcomings, making Beijing-Zhangjiakou Railway an economical and reasonable railway line at that time.
