Xinhua News Agency, Beijing, September 15th (Fan Xi, Xu Haobing) Reporter learned from China Railway Construction Co., Ltd. on the 15th that some of the infrastructure projects under construction in my country have made important progress.
In Gansu, the 8021 -meter excavation task was completed by the Lanzhou -Zhangye Third and Fourth -Line Railway New Wusheling Tunnel in the Zhangye Third and Fourth -Line Railway, which was built by the China Railway 15th Bureau Group, which laid a solid foundation for the comprehensive penetration of the tunnel in late October.
According to the person in charge of the project of the China Railway 15th Bureau Group, the construction project of the New Wusheling Tunnel Construction Project of Lanzhou to Zhangye Third Line Railway is located in the high -cold and high altitude area of the Qilian Mountain National Nature Reserve. Tunnel builders overcome many pressures such as complex geological structure, harsh natural environment, and fragile ecology, strict process standards and implementation process management to ensure that the construction tasks of the tunnel import section are successfully completed.
Lanzhou to Zhangye Third and Fourth -Line Railway is a key construction project in Gansu Province. The line passes through Lanzhou, Wuwei, Jinchang, and Zhangye. The railway is of great significance for the construction of the Gansu Hexi Corridor Passenger Channel and promoting regional economic development.
In Guangdong, the Guangdong -Hong Kong -Macao Greater Bay Area interconnection and interoperability infrastructure project — Guangzhou Beijiang Water Direction Project No. 4 tunnel is fully connected. According to the person in charge of the project in the construction unit of the China Railway 18th Bureau, the total length of the No. 4 Tunnel is 11.4 kilometers. The tunnel construction length accounted for 72.6%of the project's total length, and the construction of the first new open tunnel excavation (TBM) was used in China.
The Guangzhou Beijiang Water Diversion Project is a major livelihood project in Guangzhou to build a multi -water source safety water supply guarantee system and improve the emergency spare water source in the central urban area. The project is planned to fully build water through 2024.
In Chongqing, the right line of the Castle Tunnel of the Yuxiang Fu Line highway is smoothly connected. According to the person in charge of the project of the 24th Bureau of the China Railway, Zhongbao Tunnel is located in Pengshui County, Chongqing. The design is designed with a separate dual -hole layout. The left line is 2191 meters long and the right line is 2204 meters long. As of now, the overall construction tasks of the tunnel have been promoted in an orderly manner, and the overall progress has been completed by 95%. It is expected that the left line will be connected at the end of September.
The mileage of the construction of the Yuxiang Fu Line 280 kilometers. After the entire line is completed, it will effectively alleviate the pressure on the Yuxiang section of the existing G65 Baomao highway.
