The first super -kilometer tunnel of the West Extension High Speed Rail -Anping No. 1 Tunnel successfully penetrated

On September 13th, with the roar of the excavator, with the success of the last layer of rocks successfully breaking the wall, marking the construction of the Xiyan High -speed Railway Anping No. 1 Tunnel of the Xiyan High -speed Railway of China Railway Sixth Bureau. It is the first super -kilometer tunnel that runs through the West Extension High Speed ​​Railway, and it is also the longest tunnel that is currently connected to the entire line.

Anping No. 1 Tunnel entrance

The total length of the No. 1 Tunnel of the Xiyan High -speed Railway is 1762 meters. It is located in the loess and gully area of ​​the right bank of Beiluo River in Ganquan County, Yan'an City, Shaanxi Province.岩 岩 is the main, with difficulty in construction and high safety risks.

In order to ensure the safety of tunnel construction, the construction unit Xichengke Shaanxi Company shall guide the construction of the fine red high -speed rail and guide the construction unit to the Xiyan High -speed Railway Project Department of the China Railway Sixth Bureau. The process dynamic adjustment of blasting parameters, closely organize related processes, and further strengthen the safety control of tunnel construction. At the same time, the construction unit of the China Railway Sixth Bureau West Extension High -speed Railway Project Department vigorously promoted standardized operations and informatization control, and adopted processing workstities such as anchor rod rod drilling, self -propelled hydraulic trestle, automatic fabric system two -lined buildings, and automatic maintenance systems. Adhere to the principles of "weak blasting, governance super, shorter, strong support, strong support, early closure, diligence measurement", strictly control the tunnel super excavation, ensure the normalization of tunnel excavation quality control, achieve strong management, no error leakage, in the whole, in the whole With the joint efforts of the participants, the No. 1 Tunnel of Anping went through smoothly.

Xi'an to Yan'an high -speed railway is the first high -speed rail of the old revolutionary district of Shaanxi. It is an important part of the national high -speed railway network bag (silver) sea high -speed railway channel. The important component of the main skeleton of the font high -speed rail network is a key construction project in the "Fourteenth Five -Year Plan" period. The total length of the line is 299.8 kilometers, and the construction standard is a dual -line high -speed railway with a design speed of 350 kilometers per hour.

After the establishment of the line into operation, the operation time from Xi'an to Yan'an will be shortened from the current two and a half hours to about 1 hour. It is of great significance to optimize the national high -speed railway network layout, enhance the advantages of Shaanxi Province, and the national railway network hub.
