Chapter 697

What the?

Really figured it out!

Everyone in the command room was shocked.

Everyone thought that Gu Lu was just a break for a while, but they didn't expect that Gu Lu really calculated it.

Time.

The expressions on the faces of everyone in the command room were extremely complicated.

There is joy and relief.

But more than that, it was shocking and unbelievable!

To know.

It has only been about five minutes since Gu Lu got those data parameters.

Such a complex calculation can be done in such a short time.

This is a great challenge to the worldview of many people.

Because it sounds like a fantasy.

The supplier of the hydraulic system kept muttering the word 'impossible'.

Zheng Chun's side.

After hearing Gu Lu say that sentence with a smile, he supported the command platform with both hands and asked in a deep voice, "Professor Gu, through your calculations, how long can the hydraulic pushing system of the combined cavity be supported?"

"Twenty-four minutes and thirty-six seconds. Gu Lu replied without thinking, "The error will not exceed one second." ”

Zheng Chun's brows furrowed, "Are you sure?"

Gu Lu's tone was full of confidence, "I'm sure there is absolutely nothing wrong with this data. ”

Zheng Chun believes in Gu Lu in his heart.

Because Zheng Chun didn't think that Gu Lu would joke at such a critical juncture.

But......

In order to ensure the safety of the underwater construction workers, Zheng Chun naturally couldn't bet all on the data calculated by Gu Lu.

So, after a short silence for a few seconds, Zheng Chun spoke in a serious tone, "Professor Gu, I'll give you and your workers fifteen minutes. ”

"Fifteen minutes later, regardless of whether the welding repair of the hatch is complete or not, you must evacuate me to a safe distance, understand!"

Although Gu Lu said that the hydraulic system would not fail until twenty-four minutes, Zheng Chun set this time at fifteen minutes for the insurance period.

Leave plenty of room for cushioning.

Of course, Gu Lu was aware of the pressure that Zheng Chun's side was facing, so he nodded heavily after Zheng Chun's order.

"Chief Engineer Zheng, I am clear, I will act completely according to your orders. ”

After ending the conversation with Zheng Chun, Gu Lu and the dozen or so workers in the pipeline glanced at each other.

"Take your equipment, change into a diving suit, and go into the water with me to weld the hatch!" Gu Lu said in a loud voice.

"Yes!"

"Professor, you're going to go into the water with us?" one of the welders asked.

Gu Lu is the supervisor here, in fact, as long as he sits on the side of the pipeline and directs, there is no need to go into the water and risk it himself like them.

"Of course!" Gu Lu's tone was firm, "At this time, one more person will have more strength!"

…………

Two minutes later.

Workers quickly put on their equipment.

After that, the gate is opened and the sea water is entered.

Everyone was wearing oxygen masks and could not communicate properly, so they were only able to use a few simple gestures.

Gu Luyou was at the forefront, and was the first to arrive at the hatch of the joint cavity.

The first step in welding and repairing a hatch is to find out where the gap in the hatch is.

But.

In terms of the flow rate of the water poured into the hatch, the gap in the hatch is not too small, of course, it is not too large, otherwise it will affect the structure of the entire bonding cavity.

If that were the case, it would be possible to declare the re-docking work a failure without risking the technology to weld it.

Time is of the essence.

Gu Lu and more than a dozen welding workers conducted a quick investigation at the hatch.

Ultimately.

It was in an inconspicuous place in the hatch that the gap was found.

At this time.

Six minutes had passed since the fifteen-minute allotted time.

Underwater.

Gu Lu pointed to the position of the gap in the hatch and asked everyone to start welding.

However, due to the pressure difference between the inside and outside of the hatch, and the operation of the underwater workers due to the obstruction of the water flow, the welding process is very difficult.

No way.

Gu Lu could only beckon a few people to desperately plug the gap with their hands.

After that, the welders welded a steel plate through the notch.

I was busy for almost a few minutes.

The notch in the hatch was re-welded.

Gu Lu took out a display instrument from his arms.

The above shows that the amount of water in the binding cavity has ceased to increase.

This means that the gap in the hatch has been completely blocked.

And at this time.

Fourteen minutes had passed.

Gu Lu gave everyone a thumbs up, and then directed everyone to swim back to the pipe.

"Whew!"

Back inside the pipe interface, Gu Lu took off his oxygen mask and gasped for air.

"Everyone, we succeeded!" Gu Lu's face showed joy.

The welders also had happy smiles on their faces.

"Chief Engineer Zheng, fortunately, I am not dishonored!" Gu Lu held the walkie-talkie and reported to Chief Engineer Zheng on the other end.

Chief Engineer Zheng clenched his fists heavily, "Professor Gu, you are all good!"

The gap in the hatch was successfully welded, and a big stone in Zheng Chun's heart fell to the ground completely.

"Chief Engineer Zheng, shall we continue?" someone next to Zheng Chun asked in a low voice.

The re-docking work had just reached the second stage when he encountered such a big trouble, and the man was very worried that if he continued, he would encounter some other unexpected situations.

Faced with this question, Zheng Chun replied very simply, "Why don't you continue! There is no turning back from the start of construction, we have all come to this point, and the only choice is to continue to move forward." Everyone, listen to my orders, and the re-docking work continues as planned. ”

"Yes!"

…………

The hatch gap was repaired successfully.

The next step is to continue to inject water into the binding cavity.

A blessing in disguise.

Because of the leakage of the hatch, the amount of water in the joint cavity has increased a lot.

According to the current water injection flow rate, instead of the previously estimated three or four hours, it only takes about half an hour to achieve the same water pressure inside and outside the combined cavity, and officially enter the next link.

Half an hour later.

The water pressure meter shows that the water pressure in the joint chamber reaches the same 0.28 megapascals as the external water pressure.

Gu Lu immediately turned off the water injection valve.

By this time.

The task that Gu Law Firm is responsible for is almost completed.

After that, Zheng Chun on the water was personally responsible for commanding.

Gu Lu breathed a long sigh of relief and moved his legs, which had become a little stiff due to his long-term standing.

"Chief Engineer Zheng, next, it's up to you!"

Gu Lu looked up at the sea and muttered softly.

…………

After the water injection is completed, the final fitting is placed between the E29 and E30 segments, with only 15 cm of space from both sections.

Re-docking means hoisting the final joint and re-positioning.

The biggest risk of this is collision with E29 and E30 segments.

But Zheng Chun has great confidence to avoid this risk.
