3D animation demonstrates the process of shield tunneling, intuitive and easy to understand!

With 2000 tons of shield machine firepower in full swing, another project in China is going against the sky!

The original shield machine not only drills holes, but also lays bricks while drilling holes. This big fellow is too aggressive.

At the construction site of large-scale shield machine, when the tunnel was excavated, it was only at that moment that we realized what a big countrys heavy equipment was.

Is the 1750 ton shield machine stuck while digging a tunnel? The United States to carry 2200 tons of gantry crane rescue, help or not?
