CCTV News (News Network): Those who struggle are young. May 4 Let us approach the "Light Chaser" in the tunnel together. Faced with the most complex geological conditions, they are not afraid of hardships and bravely fight hard, and use unity, struggle and innovation to dig inch by inch among the mountains and ridges, allowing youth to shine in the places where the motherland needs it most.
This is a recent sudden surge at the construction site of Gaoligongshan Tunnel. Accompanied by a huge roar, the gushing water like a mountain torrent rushed straight towards people.
The Gaoligong Mountain Tunnel, with a total length of 34.538 kilometers, is the last tenth of the unopened section on the Darui Railway in Yunnan. It is also the first tunnel in my country to cross the Hengduan Mountains. It covers almost all the poor geology and major risks of tunnel construction. Cao Yaozu, 35-year-old chief engineer of the work area, told reporters that due to the collision zone between the Asian and European plates, the geology here is a "sparse-slag" type of porridge. The hard rock boring machine that is not afraid of hardness or softness has already struck the strike for the 43rd time. The reporter followed Cao Yaozu to the top of the cutting board of the excavator and found that the hole here was extremely narrow. The engineers had to wait like this when they came to check. Because of the sudden surge, the camera was broken.
It's so difficult, why do you still need to build it? Cao Yaozu said that the Darui Railway, which connects Dali and Ruili, is also an important infrastructure project for the joint construction of the "Belt and Road" initiative. For this reason, he and more than 300 builders have been fighting hard in the Gaoligong Mountain Tunnel for ten years.
Faced with world-class problems, Cao Yaozu and his team of experts calmly responded and worked together to overcome difficulties, looking for solutions such as large deformation of soft rocks and high-risk fault zones one by one, and all efforts were made only for the tunnel to be opened.
