Once again, they were more cautious than before.

Fine adjustments seem to be easier than overall movement, but in fact, the difficulty is greater than the overall re-docking.

Because the cross-sectional area of ​​the immersed tube is about 400 square meters, if the docking error is too large, it may cause the water stop to fail.

The water stop of the tunnel is also a new process that combines the strength of all engineers.

It has better effect than the existing water stop belt in Kuangguo, and in previous experiments, it achieved 100% anti-absorbing function.

If the water stop is affected due to the docking problem, then what is their previous efforts?

If the tunnel is soaked in water, the entire project will be meaningless.

Thinking of this serious consequence, General Manager Lin felt a little nervous and couldn't help but become more nervous about the current project.

However, General Manager Su's expression was quite natural. He whispered: "The accuracy of the gravel ridge was repeatedly measured by the instrument. As long as there is no error in the calculation, there should be no problems after this calibration."

On the foundation trough, in order to make the sinker more stable and safe, they also laid a layer of gravel ridges on the foundation trough at the bottom of the sea.

Lu Zian nodded and tapped his fingers on the screen: "These lines are gravel ridges. Although the foundation trough has been cleaned, it has not affected the gravel ridges."

After hearing their words, General Manager Lin finally felt a little comfort.

As everyone was staring at him, the sinking tube slowly moved up again.

5 cm, 4 cm...

After fine-tuning this point, the overall pull is then pulled.

Pull the sinker up by 5 mm, and the initial pull-up ends!

Without even requiring them to give orders, the divers quickly jumped into the water.

In the deep sea, the turbid sea water rippled back and forth, and divers sometimes appeared in their vision and sometimes hid in the shadows.

The light that was originally turned off was lit up again after confirmation.

The bright green light pierced the darkness and emitted a soft light with the sea water.

Never had this moment, the green is so heartwarming.

The data was transmitted quickly, and the engineers were tiring up their heads.

“…3…2…Huh?”

Someone made a low voice, unable to even believe his calculation results, and couldn't help but recalculate them.

Chief Executive Su frowned and leaned forward slightly: "How much is it? Why haven't you calculated it for so long?"

"Wait, wait a moment, I will calculate it again, maybe I did it wrong..."

This voice was filled with three points of disbelief, and a little panic and hope.

Chief Engineer Lin glanced at Lu Zi'an, looked at his faint smile that was not easy to detect, and suddenly felt his whole body relaxed.

"It's as much as you want, say it boldly!" Chief Engineer Lin was caught up in the case, and he was so proud: "Even if it's 1 cm, we deserve it!"

The staff member who was burying his head and looked up at him, looking helpless: "If it is 1 cm, I will definitely say it..."

Chief Engineer Su jumped, got up and walked over: "How much is that?"

It's not that small than a centimeter, right?

The man calculated again, and said slowly with a bitter face: "I, how did I calculate it? The error is 0.05 cm?"

Is there something wrong with the outfit, or is it touching the line when re-connecting?

0.05…How is this possible?

Halfway through, General Manager Su stopped and calmed down. Suddenly he didn't know which foot to lift next.

Chief Executive Lin was a little confused, covered his heart and glared at him: "What did you say? You say it again?"

"Zero...zero five..."

The engineers next to them rushed up and calculated quickly.

Once, twice...

“Min is also 0.05…”

"Is this data really OK?"

In the face of a huge surprise, they couldn't even believe this fact.

"No problem." Lu Zian smiled and said lightly: "Because the original error was five centimeters, if you want to adjust it to within three centimeters, you can actually adjust it to 1.5 centimeters in the upper left corner."

But he said three centimeters.

So the error is directly compressed to negligible numbers.

0.05 cm.

I don’t know who it was, so I threw down the pen in my hand and applauded directly.

Even Chief Executive Su couldn't help but raise his hands and applauded vigorously.

There was thunderous applause at the scene.

Chief Executive Lin finally breathed gently, which was being held back.

He fell down on the chair and murmured softly: "The most accurate place in the undersea tunnel in Handan is four centimeters..."

This is achieved only under the careful guidance of the German engineer team.

Not only do they be proud of it, they also don’t even show it to them, and the outside world even exaggerates their accuracy to the forefront.

Nowadays, the deepest impression of Germans is that they are strict and serious about their work...

Chief Engineer Su obviously thought of this, so he couldn't help but turn around and look at Lu Zi'an steadily.

If their data is spread, the construction industry will probably be crazy...

This accuracy is comparable to that of a machine.

"Haha, what do I do?" Lu Zian spread his hands and raised his eyebrows: "This is the result of everyone's joint efforts. How about it? General Manager Su, do you want to treat a meal tonight?"

The engineer suddenly felt energetic and started to cheer.

"Please, you must invite me!" Mr. Su, a wealthy and waved his hand: "Tonight we all go to the small cafeteria. Let's order whatever we want and eat as much as we want! All of them are in my account!"

"Wow!" Everyone was excited, they were already very happy, but now they were even more excited.

The command room was filled with joy. After General Manager Su's words came out and said bluntly that there was no limit on the number of people and jobs, cheers came from outside soon.

All the chefs returned to their posts, worried about insufficient staff, General Manager Su even asked someone to go outside to find several chefs.

This is really a big deal, and the ingredients are directly pulled from a large cart in the restaurant.

The cafeteria was very lively, and Lu Zian was toasted in various ways.

Of course, for the sake of project, they cannot really drink alcohol, so they all drink wine instead.

But even so, Lu Zian was drinking a lot.

Ying Xuan wanted to serve him several times, but Lu Zian refused: "Just be happy, this is not intoxicating, it's okay."

He was so approachable that everyone became more enthusiastic, and the atmosphere in the canteen immediately rose to a higher level.

Chief Executive Su did not go there. He held a cigarette in his mouth and slowly and in detail, reporting the entire process to his superiors in detail.

[Unprecedented high accuracy comes from the efforts and persistence of all of us, and we will strictly control the follow-up project...]

After knocking the last stop, General Manager Su gently exhaled a cigarette ring and pressed it out in the ashtray.

At the beginning, he thought that it was a joke that the official asked him to invite a craftsman like Lu Zi'an to come as a consultant, but now he suddenly realized that Lu Zi'an, the consultant, was really...

Too worth it!

The successful docking of the immersed tube in the first section gave everyone a shot of cardiac aid.

They are moving forward, producing two immersive tubes at a time, and they are docked once a month, and are full of energy.

With Lu Zi'an in charge, the accuracy of each immersed tube is very high, and the seventh immersed tube even reaches an accuracy of 0.02.

Such success gave them the illusion that it was not difficult to connect the immersed tube.

So much so that when the section 15 immersion tube was installed, they were caught off guard by a sudden abnormal return of silt.
Chapter completed!
