Almost all architectural experts in developed countries in Europe and the United States believe that the Bohai Undersea Tunnel is bound to fail!

The voices of these architects are heard all over the world through the Internet.

It was also naturally introduced to China.

In this regard, countless people in China are silent.

Because they all know that what these European and American architects say is the truth!

The construction of the undersea tunnel is indeed more difficult than everyone imagined.

As early as more than 10 years ago, the high-level preparations for the construction of the Bohai Submarine Tunnel have not started, but the main reason is that the key technical problems have not been overcome.

Even now, when the high-level announcement of the start of construction is announced, I am afraid that the technical difficulties have not been completely overcome.

Because, the known technical difficulties, can only be said to be part of the construction process of the undersea tunnel.

There is also a large part of the technical difficulties, which are unknown!

It will only be discovered and highlighted after the construction of the undersea tunnel begins.

At that time, it will be the real test!

Test the real ability of architects.

Therefore, it is almost impossible to build this undersea tunnel quickly.

Half a year?

It's nothing short of a fantasy!

The so-called five years and ten years are only a manifestation of the self-confidence of the Chinese people.

I'm afraid that from an objective point of view, it will really take more than ten years to really build!

At the same time, foreign experts are not optimistic about the Bohai Undersea Tunnel.

Architectural institute, no one responded!

They don't have time to respond, perhaps!

Because, at the same time as the completion of the undersea tunnel, the first section of the pipeline, under the traction of a 10,000-ton giant ship, entered the deepest part of the Bohai Strait.

Installation in the water!

This first section of the pipe is 300 meters long.

Thirty meters in diameter.

The interior can accommodate an eight-lane road of about twenty-four meters.

This is already a highway-level level, which can fully cope with the traffic pressure from Beihai to Ludong.

The two ends of the pipe have been tightly sealed.

This is just the first cut.

After being placed on the bottom of the Bohai Sea, the second and third sections will be put in successively......

Finally, it was connected again, and the interior was all connected.

The undersea tunnel can basically be completed.

This first section of the pipeline into the sea is the most important!

Because once this section of the pipeline enters the seabed, it cannot withstand the impact of the water pressure and ocean currents on the seabed, and if there is damage and leakage, it is equivalent to the construction of the entire Bohai Sea undersea tunnel, and the first step is to plant a heel.

If you want to continue with it, it's hard to get there.

As long as this section of the pipeline enters the water, it supports the water pressure and ocean currents, is not damaged, and there is little water seepage, then it is equivalent to a huge step forward in the Bohai Submarine Tunnel!

The next step is to pile up the pipes in quantity and connect them together.

As long as the pipes are strong enough, even "water storage operations" can be carried out.

That is to say, when you put the pipe, you don't need to block both ends of the pipe, just open it.

Seawater can get inside the pipes.

All the pipes are placed, connected together, and then the seawater inside the pipes can be emptied with a high-power water pump.

Of course, the premise is that the pipes can hold up the water pressure!

If we can't hold on, we will erect 123 kilometers of pipelines, spend endless manpower and financial resources, and then empty the internal seawater, and once the seawater is emptied, the pipeline will not be able to withstand the pressure and will be directly broken, then the previous efforts will be wasted and the losses will be extremely heavy.

Therefore, the first section of the pipeline is extremely important!

Put it in the deepest part of the Bohai Strait!

As long as it can withstand the pressure and currents of the ocean floor, everything is fine!

At this moment, a billion-ton giant ship is dragging this section of the pipeline to the deepest part of the Bohai Strait.

All major channels, live broadcast the whole process!

All the Chinese people, holding their breath and condensing, waited for the moment when the pipeline entered the water.

And there are countless people all over the world who are paying attention to this moment.

"This section of the submarine pipeline can't be too thick!"

"If it's too thick, a pipe three hundred meters long and more than thirty meters in diameter is too heavy!"

"A giant ship of hundreds of millions of tons can't be dragged at all!"

"The difficulty of construction will increase at a geometric magnification!"

"The thickness of this pipe cannot exceed two meters!"

"I'm afraid that a two-meter-thick pipeline can't withstand the water pressure of the Bohai Strait at all!"

Some European and American architects have expressed their opinions.

There is even a program in Fuso, which specially invited three Fuso architects to conduct interviews while watching the live broadcast of the undersea tunnel entering the water.

"I expect that after this section of the pipeline enters the water, the seepage index should be between 13 and 16. ”

"I'm afraid your predictions are a little too optimistic. ”

"I think that after this section of the pipeline enters the water, the water seepage index may reach more than 23!"

"I think it's possible to reach level 27!"

These three Fuso architects discussed one after another.

"A water seepage index of 27 is not far from a complete collapse!"

"I think that since Huaxia dares to conduct the test, it should have a certain degree of certainty, and the water seepage index may be reduced to below level 20. ”

"The water seepage index of about 20 also needs to be blocked with all our might, and we will do everything we can to solve it. ”

"At the beginning, our undersea tunnel in Fuso was difficult to solve because of the water seepage index of 13, which greatly delayed the construction efficiency, and finally took more than 20 years to build the undersea tunnel. ”

"Although the current material science has made progress compared with before, it is still difficult to block and solve the water seepage index above 15. ”

These Fuso architects said one after another.

In seabed buildings, there is a water seepage index.

Below level 10, only maintenance is required.

From level 10 to level 15, it is necessary to find a way to block and repair in order to ensure construction.

Level 15 or above, it is extremely difficult to block!

It will greatly delay the construction of the Cross Harbour Tunnel.

When it comes to the water seepage index above 20 levels, construction is not possible at all.

Above level 25, the pipeline may collapse directly at any time!

Three Fuso architects predicted that the water seepage index of the pipeline after entering the water was between 13 and 27.

The best look is only level 13.

It needs to be built slowly in the continuous patching and repair.

It will take about a dozen years.

And the least optimistic is that the water seepage index can reach level 27!

After entering the water, the pipe cracks!

The construction plan of the undersea tunnel will be directly stillborn......

It may take more than ten or twenty years of technical reserves before the project can be restarted.

Some Chinese people, seeing this talk show in Fusang, are also extremely heavy.

"Huaxia, come on!"

"Absolutely!"

In their hearts, they can only cheer up!

It was two o'clock in the afternoon.

A giant Chinese ship sailed into the deepest part of the Bohai Strait!

In this section of the pipeline, a large number of various testing equipment are placed.

Release the cable!

The first section of the Bohai Submarine Tunnel, at this moment, into the water!
