Xugongdi’s wall-connected equipment crosses the “difficult river tunnel”

Jul 08, 2020

The toll of the second bridge across the Yangtze River, which cost nearly 40 yuan back and forth, made the owners of Nanjing's main city and Jiangbei and Baguazhou feel distressed. But when Heyan Road is completed, the money can be saved.


At the construction site of the southern section of the Nanjing River Crossing Channel Tunnel Project, two XCMG double-wheel milling machines and one XCMG continuous wall hydraulic grab passed through the wind and the waves and crossed the river, helping this "free" fast lane to open to traffic as soon as possible.


The Nanjing and Yanlu Crossing Channel is located between the Yangtze River Bridge and the Second Yangtze River Bridge. The tunnel has a total length of 2965 meters and a design speed of 80km/h. The geological complexity is mainly composed of silty sand layer, full-section hard rock, soft and hard uneven stratum and Long distance karst area. Experts believe that Heyan Road is the most complicated and difficult large-diameter tunnel under construction across the Yangtze River in China!


As of now, XCMG XTC80/85 is under construction in the Singapore Corridor Project, with German and Korean products competing with it. During construction, the construction efficiency and stability of XCMG XTC80/85, which represents Chinese equipment, is not inferior to foreign products, and has been recognized and recognized by the local government.
