Chapter 333 Observation (first update)
"Then let's start the rectification." When the leader of the department heard this, he immediately said.

"Can this size be smaller?" The leader of the railway department looked at the steel behemoth with a diameter of ten meters and several hundred tons, and his heart was surging!

With this artifact, is there any mountain that cannot be overcome?

All difficulties and obstacles will be overcome bit by bit in front of this machine.

"The size can still be reduced, but if it is too small for various reasons, subsequent maintenance will be inconvenient, and the strength of the material...!" Liu Hai tried his best to explain to the leaders why this thing should be so big. Because we need to pile up materials.

Not only does the overall structure need to be stacked with materials, but also the cutter head needs to be stacked with materials.

"Can it be reduced to eight meters?" The leader of the railway department finally understood, because now when the equipment is undergoing major maintenance, people can get in and perform maintenance.

"At that time, we can choose some smaller people to do maintenance." The leader of the railway department added.

"In fact, it can be smaller, but it is more troublesome. Now this diameter can be maintained on the working surface. If it is smaller, the whole thing needs to be pulled out and maintained again." Liu Hai nodded.

A group of leaders were looking at this huge guy. People walking inside felt very small. The left and right sides were made of steel.

The thigh-thick hydraulic columns shone like metal under the light, and they were densely packed one by one.

This is actually a major technology of the tunnel boring machine. To advance smoothly and slowly, the shield machine needs the overall hydraulic system control capability.

The overall advancement of the shield machine is uniform and linear. If the force on the hydraulic column is uneven, it may deflect.

Manual work takes up most of the work, such as the hydraulic columns supporting the tunnel at the back.

"That's it for today. Let's continue tomorrow. We are all tired." Sun Aiguo felt distressed when he saw Liu Hai's dirty look. This young man not only designed but also assembled here to create such a big thing.

Today, except for lunch, I have been busy.

"Then rest, Comrade Xiao Liu, and take care of yourself."

"Well done, Comrade Xiao Liu." The leaders also know that everyone is very tired, especially those working on the front line, who have been busy all day.

Liu Hai took a short shower and then fell down to sleep. He was really tired today and ran up and down the machine.

But youth is good, and the same goes for other railway soldiers who woke up energetic the next morning.

Today I will continue to test the shield machine. As soon as Liu Hai left the sleeping place, he found that the leaders were here again.

The leaders ate with everyone. They ate big pork buns. Soy sauce was added to the pure fat meat, and nothing else was added. The dough was all white flour.

Bangs ate two fat buns, one as big as a fist, and felt very comfortable.

The other people all ate at least two, and some ate three or four. Liu Hai remembered that there was a little man among the railway soldiers. He looked short and skinny, but this guy was very strong, weighing 100 pounds. Carrying five bags of cement, this is 500 kilograms.

Of course, he is also very good at eating. He is so skinny that he can eat six steamed buns, the kind that are bigger than your fist, and a bowl of noodles.

The leaders watched the shield machine spin again, reaching its fastest speed today.

After the gravel coming out of the conveyor belt is transported away from the back, it is crushed and mixed with cement nearby to make cement modules.

"This method is good and can greatly save materials."

"That's right, Comrade Xiao Liu, I don't know how he got such a brain."

"With this, can we build the subway?"

"Comrade Xiao Liu said that this one is specialized in digging stones, while the one that digs soil is another kind."

"Really?" The leaders all looked at Sun Aiguo who just spoke.

Sun Aiguo made some gestures, and then said: "Comrade Xiao Liu said that building a subway is more complicated, especially if it is made of pure soil. The soil must be mined out, and then directly compacted around the tunnel, and some protective piles must be installed."

"It seems that Comrade Xiao Liu still knows some engineering skills."

"Comrade Xiao Liu just doesn't understand the specific operation, but he must understand the theory. After all, this machine has to work in a complex geological environment. This has already reached the world's advanced level, right?"

"I asked the engineers in the ministry and they didn't even know there was such a device."

"Comrade Xiao Liu is proficient in English, German, and Russian. There are hundreds of various reference books in his office."

"Comrade Xiao Liu, you can also get some advanced international academic magazines over there."

"That's Comrade Xiao Liu. Another person wouldn't be able to design it."

"Comrade Xiao Liu has actually been planning this for many years." Sun Aiguo said quickly to the side.

"Genius is genius!"

With my bangs above me, I couldn't hear the praises of the leaders below me, and my eyes were staring at the equipment.

An hour and a half later, Liu Hai stopped the machine and asked the back to transport the cement modules.

While moving the hydraulic column supporting the shield machine, smooth rock walls were exposed.

The cement modules were inlaid in a circle. Taking this opportunity, the staff operating the shield machine carefully checked the water and oil pressure of each connecting component.

At the same time, the exploration personnel used pneumatic tools to drill into the shield machine and began to drill rods on the working surface.

Liu Hai was directing from one side. When the cement modules were inlaid, the maintenance of the shield machine was also completed.

Then he continued to drive the shield machine, reaching the fastest speed.

The person in charge of the railway department looked at the tunnel wall inlaid with cement modules after the TBM machine was gone. It was hard to imagine that one day it would be so simple to build a tunnel.

"This doesn't require blasting, and the geology is more stable!"

"Burning gunfire sometimes leads to accidents. Last year, when a tunnel was built in the southwest, the gunfire shook the rocks out of the gaps, and then groundwater gushed out. From small to large, the entire tunnel was flooded in the end. Fortunately, no one was safe. "

"This kind of thing is very good. You can go through it from the front and fix it with modules at the back."

"I heard Comrade Xiao Liu say that the modules are filled with cement slurry, leak-stopping agent, etc."

"The most important thing is safety."

Everyone nodded. Now, to put it bluntly, when doing a project, you have to be prepared for accidents. Even if there is an accident just ahead, you must rush to meet the construction deadline.

At noon, there is beef stew, pure beef, steamed buns, rice and meat.

"Brother, don't drive into the woods in the future." Liu Hai had just eaten a bowl of rice and a big spoonful of beef at noon, so he went inside the TBM to take a look. The person in charge of the factory's armed force department also followed behind. Said something quietly.

Liu Hai looked at the other party in surprise, and the other party smiled, saying nothing.

Liu Hai was somewhat depressed. The car driving into the woods was not a sudden thought of Liu Hai.

But in the recent period, I have accumulated too much credit, including the sports car for Big Brother, the Hornet sports car for the dealer, assault vehicles, tank engines, night vision equipment, cranes, airplanes, and I will soon leave the country again. He also donated 10 yuan in royalties.

At this time, what does 10 yuan mean?
These things are related to many departments, and even the most sensitive troops.

Not to mention the accumulated credit for so many things in front of me!

Wouldn’t the superior leaders be muttering in their hearts?
Such a great achievement, but no money or official position?What do you want to do?I want to support my hope!
Are you ready to do big things when you grow up?
An ordinary person would definitely believe that Liu Hai is doing it for his career, but if it were someone in power, the first thing they would consider is whether they are doing it for power.

Liu Hai also knew that someone was secretly protecting him. He did make a mistake on purpose that day, but he didn't expect that it was an old acquaintance of his. It seemed that he didn't report it to anyone.

What Liu Hai didn't know was that the person in charge of the Armed Forces Department received an order from Sun Aiguo to protect Liu Hai. Therefore, when the person in charge of the Armed Forces Department saw this from a distance, he had no intention of stepping forward to see or intervene. What.The person in charge of the Armed Forces Department should remember Liu Hai well. After all, when the Armed Forces personnel were injured because of catching the enemy, Chief Liu came up with a short assault rifle in the shortest time, not to mention that there are assault vehicles in the Armed Forces now. This thing is It's a tank, not to mention it has a machine gun on it.

The person in charge of the Armed Forces Department treats these assault vehicles as treasures and wants to see if the surrounding factories can drive such vehicles.

After the other party said this, he left. From a distance, it looked like the two of them nodded and said hello.

"Thanks to my contribution!" Bangs' head suddenly became very big.

"Can't you find an excuse to make a mistake?"

"Ignore it for now, we'll talk about it when we get back!" But looking at the equipment in front of him, Liu Hai shook his head.

After dinner, we rested for an hour and everyone continued in the afternoon.These leaders were not afraid of the noise here, so they just watched from behind.

At seven o'clock in the afternoon, the shield machine had been shut down an hour ago, and Liu Hai directed everyone to check again.

"Xiao Liu, is there any problem with the operation?" After running for a whole day, the leaders stayed here for a whole day. When the machine was shut down at night and the bangs came out, the leaders asked.

"There is no problem with the operation. All that's left is to continue testing." Liu Hai nodded. The probability of problems with this semi-automatic system was low.

On the contrary, it is fully automatic. Once there is a problem, it is difficult to find because it has a complicated circuit.

When the leaders heard this, they applauded together. Everyone understood what this big guy represented.

"With so many of you coming together, is there anything good going on?" The superior leader was walking in the yard after dinner and thinking about some issues. He saw heads of several departments coming together, but these people all had expressions on their faces. smile.

"We have built a super equipment, which is used to mine tunnels weighing hundreds of tons and ten meters in diameter..." The person who came gave a rough introduction.

"Then I want to go take a look!" The superior leader was very excited when he heard this. After all, it is unheard of and unseen to dig a tunnel while repairing it at the same time. A huge iron lump three stories high turns into a What a scene!
"We are a bunch of useless people. We haven't felt tired at all since seven o'clock in the morning." The leader of the army also smiled and said.

"Just treat it as a holiday, it's rare for you guys to have a day off!"

"This Xiao Liu is always able to come up with good things." The superior leader praised again.

"I think Comrade Xiao Liu has reached the highest level in terms of mechanics, and nothing about mechanics can stop him."

"I heard from their factory director that Comrade Xiao Liu had been planning it for a long time. It was only when he started digging cellars last year that Comrade Xiao Liu put this matter on the agenda again."

"Their factory spent two days transporting parts to the test site. People in the passing village reported it, and we learned that they had created such a big guy!" These words are a bit flattering. After all, the motorcycle factory is the superior. The leadership has inspected it several times.

"As long as it can be done, that's fine!" The superior leader could only say this.

So at around eight o'clock the next morning, the superior leaders came to Mentougou in person.

The superior leader also wore a helmet and a blue overalls.

Liu Hai looked at the old man with a smile and a rosy face in front of him. He always remembered the shock of seeing 73 patched pajamas in the memorial hall. He wanted to tell the old man about the prosperous age of 2020, but he had no choice but to do his best. , let the old man see more.

Although there were problems of one kind or another in that era, compared with today, they were not a big deal at all.

"It seems that the superiors got pneumonia in their later years? How long did it take for azithromycin to come out?" Liu Hai thought in his mind that he would develop into the medical field in two years, or let his junior sister develop in the medical field. The junior sister seemed to be studying medicine later.

The superior leaders were walking inside the shield machine, looking at the huge hydraulic columns around them and the ten-meter-diameter shield machine rotating in front.

There are also rows of high-pressure pipes. These high-pressure pipes are all seamless steel pipes. Hoses are only installed where hoses are needed, as well as various pressure gauges.

The rumbling sound in my ears felt like I was in a steel world.

The center position of the shield machine actually does not move. Due to material problems, Liu Hai uses a four-stage drive, which is a four-circular drive track device.

Only when you are in the middle of the TBM can you really feel how big this thing is. It's like you are standing on the second floor, and something as wide as the third floor and the first floor are constantly rotating.

Although it doesn't seem to rotate very fast, it has such a large diameter.

The superior leaders came and all the workers were very excited.

This time we were followed by cameras.

When the shield machine has traveled a sufficient distance, it will stop and start installing the cement modules.

The superior leaders watched carefully.

After the module was installed in a circle, the leader stroked the cement module and repeatedly praised: "Okay, you guys did a good job!"

"Thank you, leader!" the worker said excitedly while working.

After the module is installed, the gap between the module and the rock is filled with cement slurry to ensure uniform stress. .

If it really doesn't work, you can lay steel bars, support a circle of formwork, and then pour a layer.

The superior leaders saw that after the cement module was installed, there were still workers inspecting the shield machine and drilling rods.

I learned about the whole process, and I was even more impressed by the bangs. Although there are related equipment abroad, the domestic one is obviously more advanced than the foreign one.

So the superior leader saw it here at 11 o'clock, talked with the workers, took photos with them, had a meal here, and then left.

After thinking about it for a while, the superiors had a big headache due to Comrade Liu Hai's recent achievements. They donated [-] yuan, not to mention the things they built.

If it were other talented people who were engaged in research and science, the superior leaders would not take it to heart.

why?
Because the things developed by Comrade Xiao Liu can make money, they can be exchanged for various equipment from abroad, they can be exchanged for foreign exchange, they can make the little guys in the third world support us, they can make the British dealers take the initiative to give us tickets, and they can make the old people The eldest brother fell out with us, but he was too embarrassed to turn against us, so he even asked for a sports car.

It can greatly improve domestic productivity and prevent our people from going hungry and exchanging food for foreign trucks and industrial equipment.

It can make farmers start paying less taxes, and it can make traffic jams appear in Kyoto.

Some time ago, my superiors took a car around Kyoto when they got off work in the afternoon. Two-wheeled motorcycles, three-wheeled motorcycles, vans, and trucks were completely different from the bicycles in my impression.

While waiting for a traffic light, you can actually see dozens of vans and hundreds of motorcycles. The superiors were shocked when they saw it with their own eyes for the first time.

A few years ago, there was a bicycle that everyone envied.

And now?There are many vans on the road, not to mention all kinds of motorcycles.

Even small aircraft made of piston engines, which are relatively backward in foreign countries, have been booked for [-] this year, and our own troops have agreed to use this kind of aircraft. In the past, we had to patrol hundreds of kilometers of uninhabited mountainous areas, and it took only a year. I patrolled a few times, because other times it was either snowing or raining, so there was no way to go.

But now there are small planes that can fly back and forth eight times a day. They are equipped with telescopes and heavy machine guns. With two more planes, uninterrupted patrols can be achieved.

The key is that the cost is cheap. In terms of accounting costs, it is not as high as a motorcycle. The use and maintenance are no different from that of a motorcycle.

All of this started when Xiao Liu started to imitate motorcycle engines, and the gears of fate changed!
The key is still so young!At less than 30 years old, you have such merit!
"Alas!" The more the superiors thought about it, the less they knew how to reward Comrade Xiao Liu!

The leaders in the department are simply doing nothing now. We can’t find any rewards anyway. Comrade Qian Xiaoliu doesn’t want it because someone else just donated 10 yuan.

Liu Hai continued to guard the shield machine and continued to conduct experiments. After all, the shield machine was a long-running equipment. In addition, these engineers had to be taught how to repair and replace the consumable parts inside.

"Xiao Liu, the dealers on Hong Kong Island are very satisfied with the two motorcycles you designed. They want 3000 units for the line you sketched, and [-] units for the one you painted, because They limit the number of sports cars." Sun Aiguo did not follow the leaders to leave, but pulled his bangs to the other side and said something.

"Director, I can take the time to design later." Liu Hai nodded. Most of the subsequent operations on the shield machine will be left to these railway soldiers. If there are any problems, they will be guided to solve them.

"You have made great contributions this time!" Sun Aiguo looked at the leader's convoy going away.

"Director, what kind of reward do you think I should want?" Liu Hai decided to hand over this problem to the director, and he failed.
