Chapter 698

The source of Zheng Chun’s confidence is the 12,000-ton crane ship called Zhenhua.

At 7:34 in the morning on February 12th.

Zhenhua crane ship came on stage again to carry out the re-docking work of the final joint.

At this time.

There is less than twenty-four hours left before the completion ceremony is held.

After the Zhenhua crane ship was in place, Zheng Chun began to use the intercom to direct the "Zhenhua" crane driver to control the crane's boom.

"Lift the griddle!"

"Get off the grill!"

Zheng Chun's eyes were fixed on the real-time picture displayed on the screen in the control room, and he commanded with a calm and composed voice.

Following the command, the large crane lowered together.

Two hours passed, and Zheng Chun issued the command hundreds of times, constantly making precise adjustments.

The deviation has been shown many times to be between 3 and 4 centimeters. Many people in the command room thought it was time to stop, but Zheng Chun did not stop.

Because Zheng Chun wanted perfect accuracy this time.

At 10:45 a.m. on February 12, the hook of the crane's boom slightly slid and lowered the 6,000-ton final joint on the foundation bed.

"Put it down!" This was the last instruction given by Zheng Chun during the hoisting.

At this time.

Fifteen hours have passed since Zheng Chun received the data deviation report from the person in charge of the interface department.

Plus directing the first docking work of the final joint.

Zheng Chun has not closed his eyes for more than thirty hours.

When the last docking command was issued, according to GPS data, the interface deviation this time was 1 to 2 centimeters.

Until then.

Zheng Chuncai slumped down on the chair, with a relieved smile on his face.

but……

After his first docking experience, Zheng Chun did not take it lightly.

The last time we connected, the GPS data also showed no problem with the deviation. However, when we got the penetration measurement data, the deviation value at the interface directly reached 17 centimeters.

So Zheng Chun immediately took the walkie-talkie and contacted Gu Lu and Deputy Chief Engineer Sun who were still underwater.

"Professor Gu, Lao Sun, please hurry up and conduct penetration measurements. I want you to measure the penetration data at this interface in the shortest possible time."

"yes!"

After receiving Zheng Chun's instructions, Gu Lu immediately called on the workers to measure the penetration data.

After arranging the various equipment, Gu Lu pressed the button to start measuring.

On the screen in Gu Lu's hand, the numbers flashed and then stopped on a certain set of data.

Looking at the penetration measurement data displayed on the device screen, Gu Lu's pupils shrank suddenly.

…………

"What, the penetration measurement data, the lateral deviation is 0.8 mm, and the longitudinal deviation is 2.5 mm. Professor Gu, Lao Sun, are you sure your measurements are not wrong?" After hearing the reports from Gu Lu and Engineer Sun, Zheng Chun's tone was thick

Incredibly thick.

at the same time.

After hearing Zheng Chun loudly shout out this set of through-measurement data, the entire command room was filled with excitement as expected.

The lateral deviation is 0.8 mm and the longitudinal deviation is 2.5 mm.

What a concept this is!

Be clear.

During the last docking, the lateral deviation data was a full seventeen centimeters.

And now...

This deviation value is directly reduced to the millimeter level.

That’s a millimeter-level deviation!

Taking a detailed look at all undersea tunnel projects at home and abroad, millimeter-level deviations at pipeline interfaces have never occurred.

If this data is true, then the Bohai Tunnel is the only one in the world.

Until then.

Naturally, China can undoubtedly rank among the first-tier countries in the construction of undersea tunnels.

Zheng Chun clutched the walkie-talkie tightly with both hands, and his slightly flushed face showed that his current mood was also uneasy.

Zheng Chun was waiting for Gu Lu and Engineer Sun's answers.

"Mr. Zheng, it's true!" Gu Lu's delighted voice came from the intercom. "When I saw this set of penetration measurement data, I was also a little unbelievable. But I had people measure it again several times.

, but it’s still this set of data, with a lateral deviation of 0.8 mm and a longitudinal deviation of 2.5 mm!”

"General Manager Zheng, we succeeded, and it was a great success!"

Zheng Chun laughed, "Hahaha, yes, Professor Gu, you are right, we succeeded!"

The re-docking work was not only successful, but also reduced the deviation at the interface to the millimeter level.

This is an unexpected surprise.

Zheng Chun turned his head, glanced at everyone in the command room one by one, and said with a smile.

"Everyone, we won the bet!"

"Oh oh oh!!"

Everyone in the command room began to applaud vigorously regardless of the image.

The reconnection was successful, which is a good thing no matter what.

Especially this re-docking reduces the deviation at the interface to the millimeter level, which will definitely become a big boast in the media.

Everyone had to admire Zheng Chun's determination and confidence back then.

Because if Zheng Chun had not insisted on re-docking, there would not be more perfect deviation data now.

And everyone's names may be erased from the current merit list and written on the pillar of shame.

"Everyone, be quiet, be quiet."

Zheng Chun pressed his hands down to signal everyone in the command room to be quiet.

"This reconnection work was successful. We have created two milestones. One is that we have actually verified the final joint construction method of 'process reversibility' in the world's immersed tube tunnel construction history. The other is that for the first time, the immersed tube has been

The data deviation at the interface of the tunnel has been reduced to the millimeter level, and all of this is inseparable from your sincere cooperation."

Two historical milestones, and either one can be recorded in the annals of history.

Although this reconnection involves great risks, the benefits are also proportional to the risks.

But now, everyone has succeeded and reaped a lot of fruits.

Proud smiles appeared on everyone's faces.

"General Engineer Zheng is too polite. In fact, we didn't put in much effort." Someone waved his hand and said sincerely, "If I say thank you, Chief Engineer Zheng would also like to thank Deputy Engineer Sun and Professor Gu who are underwater."

That man told the truth.

During the entire re-docking work, everyone only participated in the discussion of the plan. However, it was Zheng Chun, Gu Lu and Engineer Sun who were underwater who actually implemented the plan and overcame difficulties one by one.

"Haha, I will go and thank them specially." Zheng Chun laughed, then patted one of them on the shoulder, "Everyone has been up all night. Now that the re-docking work has been completed, everyone should hurry up.

It’s time to go back and rest. As for the celebration banquet, how about it be arranged after the completion ceremony tomorrow?”

"It all depends on Chief Engineer Zheng's arrangement." Everyone answered in unison.

"Okay, then everyone should go back and rest as soon as possible. Tomorrow is the completion ceremony. Please don't come here with a pair of dark circles under your eyes!" Zheng Chun laughed and sent away all the people in charge in the command room.

And this time.
Chapter completed!
