recently
The new Longtouling Tunnel of Wenyu Railway was successfully completed
So far
All 6 tunnels in the Yuhuan section of the project have been completed
Significant progress has been made in the construction of the project
At the same time, it is the next step of ballastless track construction
A solid foundation has been laid
The new Longtouling Tunnel is the longest tunnel in the Yuhuan section of the Wenyu Railway, with a total length of 1915.1 meters, and is a single-hole double-line tunnel with a maximum buried depth of 230 meters.
During the construction, the Hangzhou Hub Headquarters, together with the project department, strengthened the construction organization, reasonably optimized the change design, and effectively overcame the problems of shallow buried bias, broken belt blocks, and frequent changes in surrounding rock in accordance with the construction principles of "short footage, weak blasting, strong support, fast closure, early looping, and diligent measurement". Comprehensive use of geological survey methods, geophysical prospecting methods, advanced drilling methods, etc., to strengthen advanced geological forecasting; Equipped with advanced tooling equipment such as pneumatic rock drills, information-based intelligent lining trolleys, 3D scanners, etc., the mechanized construction and tunnel smooth blasting technology are organically combined to ensure that the tunnel construction is intelligent, efficient, safe and controllable.
The Wenyu Railway is located in the south of Taizhou City, Zhejiang Province, passing through the cities of Wenling and Yuhuan. The line leads from Wenling Station of Hangzhou-Taiwan High-speed Railway, passes through Wenqiao Town, Wugen Town, Chengnan Town of Wenling City and Qinggang Town, Chumen Town, Longxi Town of Yuhuan City, and ends at Yuhuan Station of Lupu Town, with 3 stations of Wenling, Wenling West and Yuhuan, with a design speed of 350 kilometers per hour and a new main line of about 37.17 kilometers, of which about 21.02 kilometers in Wenling and about 16.15 kilometers in Yuhuan.
Wenyu Railway is a passenger dedicated line integrating road network, intercity, tourism and economic development functions, mainly undertaking intercity passenger flow. After the project is completed and put into operation, it will fill the gap of the railway in Yuhuan City, realize the new traffic pattern of "county-to-county railway, full coverage of the railway network" in Taizhou, and is of great significance for accelerating the construction of a one-hour high-speed rail traffic circle in Zhejiang Province, improving the layout of the regional railway network, and promoting the development of tourism intermodal transport along the line.
