Wu Zhong revealed that the first shield machine of “Made in Wuhan†was off the assembly line of Wu’s factory in the Fangfang Foshanling Park in the East Lake Development Zone.
The shield machine, whose full name is the shield tunneling machine, is a special engineering machine for tunneling. It integrates light, machine, electricity, liquid, sensing and information technology. It works with a cylindrical steel component along the tunnel axis. While advancing forward, excavate the soil, transport the soil, assemble the tunnel lining, and measure the steering correction.
In 2004, Wuzhong Group and Germany Herrenknecht signed a framework agreement for the manufacture of shield machine, and the production of the Chinese shield machine has a production base. The first user is the municipal group, which will be used for the 20th and 4th lines of Metro Line 2 and Line 4. The municipal group said that according to the needs of engineering excavation, the shield will be officially on the job.
The first Han Shield has a length of 75 meters and a design life of 15 kilometers. Including shield, cutter, frame, connecting rod and other parts. Because it is too long, it is divided into several sections and placed in the Wuzhong factory area. The main driver is also installed during the formal construction.
