Chapter 695

The water filling time is one hour.

This time.

According to the deformation pressure detector in the binding cavity, the pressure in the cavity has reached 0.1 megapascals at this time.

But......

Just when Gu Lu and everyone in the command room thought that this process would go smoothly.

Suddenly.

The unexpected happened!

"Bang!"

There was a loud bang.

Gu Lu could clearly see through the glass door at the interface that the re-welded steel door of the joint cavity was leaking.

And the water column is still very high.

A rough estimate shows that it is about five or six meters high.

Due to the huge pressure difference between the inside and outside of the binding cavity.

The seawater outside the cavity poured into the cavity along the gap in the hatch.

Buzz!

At this time.

The alarm sounded.

This is the embodiment of the overwhelm of the hydraulic jacking system of the combined cavity and the sealed water-stopping system.

Because......

According to the previous calculations.

The maximum water velocity that the binding chamber can withstand is 0.8 cubic meters per second.

And now.

Due to the gap in the hatch, the sea water rushed in along the gap.

So.

The flow rate of the water is at least one cubic meter per second.

With this flow rate, it is very easy to scrap the hydraulic jacking system and the sealed water-stopping system of the final interface.

Once the hydraulic jacking system and the sealed water-stopping system are scrapped, it means that the re-docking work has completely failed.

Moreover......

It will take at least a month or two to repair the final joint and dock again.

But tomorrow we will have a completion ceremony.

Not to mention a month or two.

Even if it's a day or two, the Bohai Tunnel project team doesn't have it.

The situation, because of the leakage of the hatch at the joint cavity, suddenly became extremely serious.

At this time.

It's easy to be careless and lose everything.

............

interface.

The flashing red light of the siren shone on Gu Lu's face.

Gu Lu clenched his fists, and his face was extremely ugly.

Gu Lu was very clear.

How much of an obstacle will a leak in the hatch door to the entire re-docking operation?

Meanwhile.

The construction workers standing behind Gu Lu also became noisy.

They have been working for many years, but the current situation is the first time they have encountered it, so some of the six gods have no master, and they don't know what to do except panic.

At this time.

Zheng Chun, who was sitting in the command room, of course discovered the situation on Gu Lu's side, he held the walkie-talkie and asked anxiously, "Professor Gu, what's the situation on your side?"

A wry smile appeared on the corner of Gu Lu's mouth, and he replied truthfully, "Chief Engineer Zheng, the hatch ...... It's leaking!"

Rumble!

Hearing Gu Lu's words, Zheng Chun's brain instantly roared, and he almost lost the ability to think.

"The hatch is leaking, the hatch is leaking......" Zheng Chun muttered to himself and slumped in his chair.

As the chief engineer of the Bohai Tunnel, Zheng Chun knows better than anyone what a leaking hatch means.

Equally.

The rest of the people in charge in the command room also got the news that the hatch was leaking.

Thereupon.

One by one, they complained.

"It's leaking, it's leaking, it's good, it's good!"

"I said a long time ago, it shouldn't be re-docked, it shouldn't be re-docked, now it's good, something went wrong!"

"Yes, the risk of re-docking is too great, no, the plan has just been implemented to the second stage, in addition to such a big problem, if it continues in the future, maybe there are still many tribulations waiting for us!"

"Alas, don't complain about this, the top priority now is to think about how to deal with the current leaking hatch!"

There was a lot of noise in the command room.

On the chair in front of the command platform, Zheng Chun stood up with difficulty holding on to the chair.

Zheng Chun is worthy of being the chief engineer of the project, even in the face of the current difficult situation, he still relies on strong resilience and quickly eases up from his autistic state.

Right now......

Whether you want to continue the re-docking work is another story.

However, it is very important to solve the problem of leakage of the hatch.

If you want to solve the leakage of the hatch, the most direct and simple way is, of course, to have people weld the hatch with a gap.

So Zheng Chun held the walkie-talkie and began to give orders, "Professor Gu, let the workers go and re-weld the gap in the hatch." ”

Zheng Chun's voice giving the order was not small, so the rest of the people in the command room could hear it.

But......

As soon as Zheng Chun gave the order, one person hurriedly stood up.

"Absolutely not, Chief Engineer Zheng, absolutely not!" It was none other than the supplier of the hydraulic system in the command room who stood up to stop Zheng Chun.

After listening to Zheng Chun's arrangement, the supplier's shocked face changed greatly, and he stood up directly to dissuade Zheng Chun regardless of any rules.

Zheng Chun just stared at the supplier, "Give me a reason?"

The supplier quickly explained the reason to Zheng Chun, "Zheng Gong, according to the current flow rate of the leaking water in the hatch, the hydraulic system of the joint cavity will soon be unable to support it and will be completely scrapped. ”

Once the hydraulic jacking system is scrapped, the most direct impact is that the hatch will immediately crack and explode, and the collapsed hatch fragments will cause great impact......! It's unimaginable!"

After listening to the supplier's explanation, Zheng Chun's face changed.

According to this supplier.

If the workers were to weld the hatch of the joint cavity, there would be casualties if they were not handled properly.

The price is too heavy.

At this time, Gu Lu's voice came from the walkie-talkie, "Chief Engineer Zheng, what the man said just now is right, once the hydraulic system of the joint cavity fails, the impact force caused by the pressure collapse of the hatch door is something that the human body cannot bear at all." ”

Hearing Gu Lu say the same, Zheng Chun did not doubt him.

But......

Although the collapse of the hatch is extremely dangerous, it does not mean that the current situation is dead.

The hatch collapse is caused by the failure of the hydraulic system.

so

You only need to rush to repair the leakage of the hatch door before the hydraulic system fails?

It's not hard to think of this method.

Thereupon.

Zheng Chun once again looked at the supply, "Can you calculate the time when the hydraulic jacking system fails?"

The vendor nodded, "Yes." ”

Zheng Chun's face was overjoyed, "Then hurry up and calculate." ”

The supplier rubbed his hands and looked embarrassed, "Chief Engineer Zheng, I said before that I don't specialize in this, so I can calculate it, but it will take at least about two hours." According to my estimates, the hydraulic system can last for half an hour at most. ”

"!" Zheng Chun scolded a rare dirty word.

What is the difference between what the supplier said just now and not saying it?

"Chief Engineer Zheng, to be honest, I really can't do anything!" the supplier shook his head and sighed.

Zheng Chun was also sighing.

Just when Zheng Chun's whole person was invaded by despair, Gu Lu's voice came from the walkie-talkie, "Chief Engineer Zheng, let me come!"
