Zitong County, Shiniu Town.

After two days of investigation in Rongcheng, Huang Xiuyuan came here.

Not far from the ancient Jinniu Road in Shiniu Town, there is a research institute called Tunnel Excavation Research Institute hidden among the mountains and ridges.

The institute is located on the hillside and uses silicate-sodium chloride material to build super highways, combined with silicon nanoplating and ferrosilicon nanowires.

This integrated building built by new building materials is very suitable for landslides and earthquakes in areas like Shu Province, which are prone to landslides and earthquakes. It is also more than enough for building materials, plus the roof solar panels, fresh water and food to be stored. Even as a doomsday base, it is more than enough.

Standing on the observation deck of the institute, looking into the distance with lush greenery, hidden in the Taurus Ancient Road, Huang Xiuyuan exclaimed:

"The difficulty of Shu Road is as difficult as climbing to the blue sky! Cancong and Yufu, how confused is the founding of the country? You will be 48,000 years old and will not connect with Qin Pass. There is a bird road in the west, which can cross the top of Emei. The earth collapses and the mountains destroys the heroes and dies, and then the ladders and stones in the sky are connected together."

"This ancient Taurus Road is the mountain opened by Wu Ding in the King of Shu back then. It is said that Wu Ding was buried by a mountain collapse in Zitong." Yang Shuli, chief researcher of the Tunnel Excavation Research Institute, said with a smile.

Huang Xiuyuan knew the legend of Wuding's opening of the mountains. In the future archaeological discoveries, a pre-Qin era ruin was discovered near Wuding Mountain in Zitong County. According to archaeology, it was determined that Wuding escorted the Wuding escort the Wuwo of Qin.

All signs from the archaeological site indicate that when the convoy arrived in Zitong on the Jinniu Ancient Road, they encountered a landslide, and the entire wedding convoy was buried near Wuding Mountain in Zitong.

Later, the Qin State adopted the ancient Taurus Road to enter Shu and destroyed the Kaiming Dynasty. In addition, it was spread by rumors, and gradually became the Five Dings and opened mountains and a series of legends.

Putting away this distant memory, Huang Xiuyuan and Yang Shuli walked into the institute, and the integrated building built with new materials added a sense of science fiction to the entire institute.

Half a month ago, he approved a 2 billion Southwest Hope Primary School upgrade and renovation plan. First, he upgraded and renovated the mountainous Hope Primary School in the earthquake zone and built it into an integrated building.

The official also plans to gradually promote infrastructure and high-rise buildings in the southwest, requiring the use of new materials to ensure the overall seismic resistance and can be improved to earthquake resistance of magnitude 8 to 9.

The two walked into the Tashan building of the institute. There was a huge tunnel inside, which was the experimental site of the Tunnel Excavation Institute.

Yang Shuli took him to the protective replacement area beside him, changed his protective suit and helmet, and came to the experimental area where the tunnel excavation was discovered.

Their standing position has been laid with high-strength boards around, which is enough to ensure the safety of the interior.

More than a dozen researchers were wearing protective suits and protective helmets, operating various equipment, and working in the rock formations in front.

"Chairman, this is the new excavation plan of Wu Ding Plan." Yang Shuli said, pointing to the equipment in front of him.

Huang Xiuyuan picked up the customized tablet handed over by Yang Shuli, which contained various information about the "Five Ding Plan". In addition to the Suiren Department, this project also participated in the Academy of Engineering, Academy of Sciences and several universities.

In traditional tunnel excavation construction, either overall excavation and landfill (mostly used in early shallow subways), blasting excavation, and in recent years, the more commonly used shield machine excavation is used.

No matter which solution is, the construction difficulty and cost will increase exponentially when encountering dense rock formations, especially for areas such as China with complex terrain, southwest and southeast road construction, the probability of tunnel excavation is almost 100%.

Although the shield machine is good, the excavation speed is also not fast and the excavation cost is quite high.

In order to promote the Western Development Strategy faster and smoother, the Suiren Department and the Academy of Engineering took the lead in establishing this research institute.

After looking at the details on the tablet, Huang Xiuyuan looked up again and looked at the construction site not far away.

Several hot and light red water flowed down above the rock formation and flowed on the surface of the rock formation.

The researcher pressed the power-on switch, and the current passed through the light red liquid, causing a chemical reaction on the surface of the rock wall. The six-cone ball oxygen in the liquid began to plunder the silicon atoms in the rock formation and liberate a large amount of oxygen.

The ventilation system extracts the dense oxygen in the working area and pulls the light red water body of the ground pool back into the circulation system.

After twenty minutes of power on, the researcher pressed the switch off.

The excavator stretched out the bucket and scraped the rock layer, and large tracts of rock layer collapsed, like the kind of severely weathered limestone.

After scraping for a while, Huang Xiuyuan had visually estimated that he had dug half a meter deep.

"At this depth, the decomposition solution should not penetrate, right?"

Yang Shuli explained with a smile: "We use hole drilling assistance. Each time we make dense small holes at a depth of 0.6 meters, stuff them into a water-absorbing sponge, and pour the decomposition solution, these decomposition solutions will follow the sponge and enter the rock body inside the rock body. With the cracks in the rock formation itself, the rock formation depth can be destroyed by power on 0.5 to 0.7 meters."

Just as the two were talking, the excavator had scraped off the corroded parts of the rock formation, revealing the uncorroded rock formations and some shallow holes.

The excavator dug the earth onto the sand and stone conveyor belt next to it and transported it out of the operation area.

Another machine with a dense drilling machine began to work on the rock formation. The high-hard drill bits operated at full power. After half an hour, rows of dense small holes were drilled.

Then use a mechanical machine to stuff the water-absorbing sponge, pour the decomposition solution, and decompose the rock formation with electricity.

One cycle goes down, in about two hours.

"The efficiency is still a bit slow, and one shift only digs more than two meters deep." Huang Xiuyuan was obviously a little dissatisfied with this speed.

The shield machine can be pushed 6 to 10 meters every day in the hard rock strata. Even if the new excavation technology is operated for 24 hours, it will only have a progress of six or seven meters, which is not enough to form an overwhelming advantage.

"Chairman, the current operation method is actually just for experiments. We will combine the shield machine to conduct joint operations testing." After Yang Shuli finished speaking, he found another experimental plan on the tablet computer.

Huang Xiuyuan took it and took a look.

The decomposition method combined with the joint operation of the shield machine can indeed effectively improve the operation speed in supercomputing simulation calculation.

But in reality, it is not that simple. The reason is that the six-cone ball oxygen in the decomposition solution has super electrolytic properties. Once powered on, it will plunder the surrounding atoms and produce a large amount of high-purity oxygen.

In this way, if the decomposition method is combined with the shield machine, it is necessary to ensure that the shield machine is not decomposed by the decomposition solution. This requires very high control of the temperature and current intensity of the decomposition solution.

The current solution is to replace part of the shield machine into elements that are not easily plundered by the decomposition solution, preferably materials with a relatively large difference in temperature, current and required by silicon atoms.

As for the problem of high-purity oxygen, it is not difficult to solve.

Only by solving these problems is necessary, combined with the decomposition method and shield machine, it is not difficult to push 30 meters a day.

Even granite-level hard rocks are no different from ordinary loess layers under the corrosion of decomposition.

Huang Xiuyuan ordered: "You should make a decision with China Railway as soon as possible and set up a shield machine to test it."
