The rise of nanometers

Just after the Guiyang-Bijie Super Highway was completed and opened to traffic, Feipeng Group and China State Construction Engineering Corporation won a new project.

Kangding City.

Fang Tuoye, general manager of Feipeng Construction of Feipeng Group, Li Nanbo, general manager of a branch of China Construction Group, and Li Mofan, chief engineer of the Design Institute of the Ministry of Construction who is responsible for highway planning and design, are at the temporary headquarters of the project in Kangding, Discussing this new project.

This new project is to build a new super highway from Kangding to Lhasa.

Li Nanbo looked at the terrain sand table in front of him, turned around and asked: "Mr. Fang, what is your company's opinion?"

"If we extend the old National Highway 318, it will indeed be much faster, but our construction must be completely closed, which does not meet the requirements. After all, Highway 318 cannot be closed casually for construction." Fang Tuoye said a problem.

Faced with this problem, everyone present was really embarrassed. The original roads into the snowy area were Highway 318, 317 and 214, which are very core life transportation lines.

The southern route of National Highway 318 has a relatively large population along the way and relies more on the only road transportation, so it cannot be closed for construction casually.

Chief Engineer Li Mofan said helplessly: "It seems that we can only choose a new route."

After speaking, he took out several design plans. Although there were no signs of construction of the Sichuan-Tibet Expressway before, related planning and exploration had actually been carried out for decades, and the Planning and Design Institute had a large number of related planned routes.

Everyone looked at it for a long time. Although there were several planned routes, it did not mean that these plans could be used.

Times are progressing and technology is developing.

Now and then, the previous planning route only took into account the economy and technology at that time, and may not be suitable for the present and the future.

"Let's set the tone first!" Fang Tuoye continued: "According to the current technology, tunnel excavation technology is very convenient. My idea is to keep it straight and reduce the slope."

Li Mofan nodded: "Well, Fang is right. According to the current technical conditions, there is really no need to make too many corners."

Soon they discussed a rough plan. This section of the super highway from Kangding to Deda is roughly similar to the route of National Highway 318.

This section is the eastern section.

As for Deda heading west, it does not go with the 318 National Highway. Instead, it chooses to cross Shaluli Mountain, Jinsha River, Mangkang Mountain, Canglan River, and Hengduan Mountains from Deda, passing through Gebo, Bamu, and Meiyu along the way, and finally arrives at Basu.

This section is the middle section.

Starting from Basu is the Western Front.

While everyone was discussing the highway route, surveyors had already rushed to the front line. Since the eastern section was constructed parallel to National Highway 318, the planning and design institute had already completed the basic survey work.

The exploration personnel now need to do work on the Shaluli Mountains, Jinsha River and Mangkang Mountains between Deda and Gobo.

Between the mountains and ridges.

There are about a hundred people in the joint exploration team wearing exoskeletons. In addition to the exploration personnel, there are also thirty-five multi-legged mechas in the team.

These multi-legged mechas are civilian versions purchased by Feipeng Group and are specially used for special operations in mountains.

In the mountains about 13 kilometers away from Deda, this is already a very high mountain range. To use a poem to describe it, it is: thousands of mountains and birds have disappeared, and thousands of people have disappeared.

Song Zhigao, who had just graduated from Southwest Jiaotong University, was deceived by Feipeng Group into this deep mountain forest. After climbing a hillside, he picked up the kettle and took a sip of water.

At this time, the sky gradually darkened.

The leader of the exploration team shouted on the intercom: "Everyone is preparing to set up camp. We will make do here tonight."

After a few days, although it was very hard, Song Zhigao got used to it somewhat.

The tent-building materials were unloaded from a multi-legged mecha. Even with the assistance of exoskeletons, everyone was panting after setting up the tent.

The strong altitude sickness made many people look pale, but several local guides were alive and kicking. After they were equipped with exoskeletons, they were even more powerful.

While it was still dark, Song Zhigao picked up his telescope and observed the uninhabited mountains.

A calloused hand handed him a bottle of mints.

"Does it feel very hard?"

Song Zhigao took the mint candy, poured a piece into his mouth, and replied with a smile: "It's not bad. It's just that the high fever is a bit difficult, but everything else is fine."

A middle-aged man in his forties took out a cigarette, lit it, and blew out a smoke ring: "You live in a good era. Two of my comrades died while exploring the Hengduan Mountains."

"It will get better and better. One day, this snow-covered plateau will also be unimpeded." Song Zhigao consoled him.

The middle-aged man looked into the distance in silence, and the setting sun quietly sank into the other side of the mountain.

Half an hour later, a bright yellow light lit up in the camp. This light was so lonely among the mountains, like the morning star before dawn, guiding the people towards a bright new era.

Song Zhigao took a portion of self-heating fried rice and ancestral chili sauce, which were all military rations.

Although the exploration team has many mechas to transport supplies, most of the supplies they carry are exploration equipment, and the food they can only eat is simple.

However, Feipeng Group still provides some extra food, such as quick-frozen dumplings, quick-frozen beef, and frozen vegetables and fruits.

Song Zhigao took a piece of his favorite braised eel and fried cucumber, and wolfed them down with fried rice and chili sauce.

After dinner, everyone was not idle, but organized and analyzed the exploration data collected during the day.

The middle-aged man who spoke to Song Zhigao in the evening carefully marked something on a geological survey map.

The team leader looked at the map for a while, then raised his head and asked, "Guoqiang, which direction do you think we should take tomorrow?"

The middle-aged man thought for a while: "Go to the southwest! The rock formations there are suitable for the next step of drilling."

"good."

The middle-aged man turned around and ordered: "Zhigao, prepare for tomorrow's rock specimen testing, don't be in a hurry then."

"Understood." Song Zhigao nodded.

The discussion and arrangement work continued until about 11 o'clock in the evening. Except for the two people who took turns to watch the night, everyone got into their sleeping bags.

The night at high altitude is deserted and mixed with the biting cold wind, making people shrink involuntarily.

The next day, the sun just came out.

The camp was cleared and the exploration party moved on to the southwest.

The mountains here are densely covered with all kinds of ancient and primitive vegetation, and also hide all kinds of strange animals. Not only are there geological and climatic dangers, these animals and plants also present some dangers.

In many areas, even locals rarely set foot in them. This place can no longer be said to be rare, but a real no-man's land.

Coming down from the mountains and entering the hot and humid deep valleys, the plants here are denser and the trees are taller, as if you have suddenly gone from the cold zone to the tropics.

At around 2:30 in the afternoon, with the help of the multi-legged mecha, the exploration team started drilling work halfway up the mountain.

The drilling equipment was removed from the multi-legged mecha, and a dozen professional drillers drilled holes into the rock formations deep underground.

The roaring sound of the engine caused waves of roaring echoes in the mountains. This was an echo of the industrial age.

Soon a rock sample appeared in Song Zhigao's hands.
