Chapter 695

Water filling time is one hour.

This time.

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

but……

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

Sudden.

An accident happened!

"Bang!"

There was a sudden loud noise.

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

And the water column was still very high.

At a rough estimate, it's about five or six meters high.

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

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

Buzz!

At this time.

The alarm sounds.

This is a manifestation of the overload of the combined chamber hydraulic push system and sealing water stop system.

because……

According to the previous calculation.

The maximum water flow rate that the combining chamber can withstand is 0.8 cubic meters per second.

And now.

Because there was a gap in the hatch, seawater poured in all at once along the gap.

So.

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

This flow rate can easily cause the hydraulic push system and sealing water stop system of the final interface to be scrapped.

Once the hydraulic push system and sealing water stop system are scrapped, it means a complete failure in the re-docking work.

and……

It will take at least one or two months to repair the final joint and connect it again.

But the completion ceremony will be held tomorrow.

Let alone one or two months.

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

The situation suddenly became extremely serious because the hatch at the coupling cavity was leaking.

At this time.

It's easy to be careless and end up losing everything.

…………

interface.

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

Gu Lu clenched his fists tightly, his expression extremely ugly.

Gu Lu knew it very well.

How much of a hindrance will a leaking hatch have to the entire re-docking operation?

at the same time.

The construction workers standing behind Gu Lu also became noisy.

They have been working for many years, but this is the first time they have encountered this situation, so they are a little confused and don't know what to do except panic.

At this time.

Zheng Chun, who was sitting in the command room, of course noticed 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 Gu Lu's lips, and he answered truthfully, "General Manager Zheng, the hatch...is leaking!"

boom!

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

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

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

same.

Several other persons in charge in the command room also received the news that the hatch was leaking.

then.

Everyone complained one after another.

"It's leaking, it's leaking, what should we do? What should we do?"

"I have long said that we should not re-docking, we should not re-docking, now it's better, something went wrong!"

"Yes, the risk of reconnection is too great. No, the plan has just been implemented in the second phase. Apart from such a big problem, if we continue, there may be many hardships waiting for us!"

"Hey, stop complaining. The most urgent task now is to think about how to deal with the current hatch door leakage problem!"

The command room was noisy.

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

Zheng Chun deserves to be the chief engineer of the project. Even in the face of such a difficult situation, he still relied on his strong resilience to quickly recover from his autistic state.

Now……

Whether we should continue the re-docking work is another matter.

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

The most direct and simple way to solve the problem of hatch door leakage is, of course, to have the gapped hatch doors welded together.

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

Zheng Chun's voice when issuing orders was not quiet, so everyone else in the command room could hear it.

but……

Just after Zheng Chun gave the order, someone hurriedly stepped forward.

"You must not do it, Chief Engineer Zheng, you must not do it!" The person who stood up to stop Zheng Chun was none other than the supplier of the hydraulic system in the command room.

After hearing Zheng Chun's arrangement, the supplier's face changed in shock, and he stood up 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, "Mr. Zheng, according to the current water flow rate of the hatch door leakage, the hydraulic system of the coupling chamber will soon be unable to support it and will be completely scrapped."

"Once the hydraulic push system is scrapped, the most direct impact will be that the hatch will immediately burst and explode, and the flying hatch fragments will cause a huge impact! And if there were workers in the cabin at that time,

If work is carried out at the door, the consequences... are simply unimaginable!"

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

According to this supplier.

If workers are allowed to weld on the hatch of the coupling cavity, if this is not handled properly, there may be death or injury.

This price is too heavy.

At this time, Gu Lu's voice came from the intercom, "General Manager Zheng, that person is right. Once the hydraulic system of the coupling chamber fails, the impact force caused by the pressure collapse of the hatch door will be caused by human damage."

The physical body simply cannot bear it."

Hearing Gu Lu say the same thing, Zheng Chun did not doubt that he was there.

but……

Although it is said that the collapse of the hatch door will cause great danger, it does not mean that the current situation is in a dead end.

The door collapsed due to the failure of the hydraulic system.

So,
To be continued...
