Beijing--Zhangjiakou High-speed Train Tunnel

 In 1909, the Jingzhang Railway, which was designed and built by Zhan Tianyou, was the first railway built independently by the Chinese. It solved the huge construction problems with the "human" shape design scheme. Jingzhang Railway Tsinghua Park Station with a history of 100 years, has been retained to this day. Today, in order to commemorate Zhan Tianyou, the tunnel boring machine that digs the Tsinghua Park tunnel is named "Tianyou".

The Tsinghua Park Tunnel is the largest high-speed railway tunnel boring currently excavated in China. It is also the only tunnel constructed by the shield method. It is a high risk tunnel with large diameter shield of single tunnel and double line across the most complex stratum and most important buildings, which is located in the core area of the city at present in China.
