February 22，Liugong Excavator Labao Factory Tongxin Lake， Engineer Liu922FTNThe tunnel machine is dispatched in batchesThe ceremony was held，10 sets of 922 shipped in this batchFTNWillDeliver to the customerBe used forTunnelDig、Construction work。

The tunnel passes through mountains and becomes a thoroughfare.

China has a vast land，The terrain is rugged，Just the mountains、Plateaus and hills cover about 67% of the land area% ，And intermingled with rivers.、Sea area、Mountains and other terrain。The mountains are boundless，The peaks rise one after another，How many families who can't eat on the mountain?，Because the road is difficult, the dream of life is blocked by the vast mountains.。In ancient times, the foolish old man moved mountains.，Now the penetration of the tunnel has finally turned the natural moat into a thoroughfare.。At present, China has the largest number of highway tunnels in the world.、Fastest growing country。
