The starting point is located on the southwest side of the original highway,
It's 30 kilometers long, with four viaducts and a tunnel along the way,
The difference between the start and the finish is 350 meters,
Seen from above, the road is like a dragon hovering over the mountains,
It is known as the "highway on the cloud".
Due to the complex terrain of Tianlong Mountain,
The highway has a vertical drop of 350 meters from the start to the end.
With an average height of three meters for a one-story residential building,
That's the height of a 116-story building, which is a huge difference,
That's why there are so many big bends in this section.
"Internet celebrity three-storey Viaduct"
The birth is to reduce the height difference, improve driving comfort.
All viaducts are made of steel box girders assembled and welded,
18,000 tons of steel for four viaducts,
Among them, more than 7,000 tons of steel are used for "Internet celebrities" viaducts.
The steel box girders are "prefabricated off-site and assembled on-site",
Use crawler crane and wheel crane to work together.
Not only that, but the road uses a lot of new technology,
Some are even being adopted for the first time in the whole province,
For example, epoxy asphalt is used on elevated roads,
This asphalt binds better to steel beams,
And has very good ductility, can prevent late cracking.
Considering that steel beams are malleable under temperature changes,
The elevated expansion joint also uses a multi-directional displacement comb plate,
Can be compatible with multiple directions of expansion.
