The reporter learned from the Xi'an Bureau of 188bet Live Casino on the 12th that on April 11, the Xiling Tunnel, a key control project of the Xi'an to Shiyan High-speed Railway (hereinafter referred to as the Xi'an-Shiyan High-speed Railway), which was built by the Shaanxi Company of Xicheng Passenger Special Co., Ltd. and constructed by 188bet Live Casino No. 7 Bureau, was successfully completed. This is the longest level I high-risk tunnel among the tunnels that have been completed in the national high-speed railway project. The completion of the tunnel has laid a solid foundation for the subsequent ballastless track construction of Xishi High-speed Railway.

The Xishi High-speed 188bet Live Casino Xiling Tunnel is located in Shangzhou District, Shangluo City, Shaanxi Province. It is located in the low Zhongshan area of ​​the Qinling Mountains. It is a double-hole single-line tunnel. The left line of the tunnel is 18.083 kilometers long and the right line of the tunnel is 18.032 kilometers long, totaling 36.115 kilometers. The geological structure is complex and the construction is difficult.

During the tunnel construction process, the construction unit uses cantilever boring machines, anchor drilling rigs, self-paved intelligent lining trolleys, automated monitoring and measurement systems and other tooling equipment to ensure construction progress and quality. At the same time, with the help of geological radar, three-dimensional laser scanning, drone tilt photography and other technologies, the construction parameters are adjusted in a timely manner, significantly improving construction efficiency.

The Xishi High-speed 188bet Live Casino is an important "no" in the Shaanxi "Mi"-shaped high-speed 188bet Live Casino network. The main line of the high-speed 188bet Live Casino is 256.7 kilometers long and has a designed speed of 350 kilometers per hour. It passes through Xi'an City, Shangluo City, and Shiyan City, Hubei Province, and connects to the completed Hanshi High-speed 188bet Live Casino. The total length of the Shaanxi section is 169.4 kilometers. This section has newly built five stations, namely Xi'an East, Lantian, Shangluoxi, Shanyang and Manchuan Pass.

After the opening of the Xishi High-speed 188bet Live Casino, Xi'an to Shiyan will arrive within 1 hour, and the fastest running time of the train from Xi'an to Wuhan will be shortened from the current 5 hours to about 2.5 hours, which is of great significance to further improve the national high-speed 188bet Live Casino network and drive economic and social development along the route.
