I Have a Mansion in the Post-apocalyptic World

However, after thinking for a long time, Jiang Chen also did not understand what this “just in case” meant.

Is it to leave a fire for the Third Reich, or for something else?

Moreover, this fortress is only a design drawing. Whether the head of state sent people to Antarctica and built the doomsday fortress according to the instructions of the Venezuela remains unknown. And as far as the position on this picture is concerned, the fortress seems to be in a blizzard all year round. Whether you can survive in such a place is also an unsolved mystery.

Going to the South Pole to see it?

This idea suddenly emerged in Jiang Chen’s mind and expanded in an uncontrollable manner.

The refuge can not control the direction of the war, and at most provides a grave for the losers. No matter what you think, it doesn't make sense to do so. However, the survivors of the void will not insert a piece of useless information into this information for no reason. The reason why they do this is definitely their reason...

What could it be?

......

The next day, Jiang Chen, who had already enjoyed his life in Penglai, returned to Coro Island with Aisha and Xia Shiyu.

For work reasons, Natasha took the plane the day before the charity party and returned to Moscow. Therefore, on the return flight, only Jiang Chen and their three people.

Back on the island, Xia Shiyu’s first thing was to go home and put luggage, and the second thing was to go to the Fuxing Building. I have not stepped into the office door for a week, and the accumulated work must be as high as the hill. Although her assistant can help her deal with some of the documents, many of the problems involved in the group's business direction must be decided by her main heart.

Jiang Chen returned to the villa with Aisha, and after a short break, he began to get busy.

On the one hand, he is preparing for the trip to Antarctica. On the other hand, he is also planning to build a submarine road tunnel to connect Panuji Island into a whole. In this way, people do not need to take a boat at the same time, and can drive directly to any corner of the new country.

To be rich, to build the road first, this is the unchanging truth. If there is such a submarine tunnel that can connect the nine islands of the Panu Islands into one, it will have a huge boost to the economy of the whole new country.

Needless to say, once this tunnel is completed, the demand for cars in the new country will definitely rise by one level.

Having said that, building this day's tunnel is not an easy task.

There are many ways to build a subsea tunnel. There are four main representative methods, such as the Drilling and Explosion Method in Qingdao and Xiamen, the immersed pipe method in Xiangjiang, the tunneling method in the English Channel, and the Japanese shield method.

However, all four methods have something in common.

That is expensive! Not ordinary expensive!

Take Huaguo as an example. The Dalian-Yantai high-speed railway submarine tunnel under construction is under construction for 1km. The construction cost is as high as RMB260 billion, and the average cost per kilometer is more than 2 billion! Even if the cost of high-speed rail is 129 million per kilometer, it is still a horrible number to build such a pipeline!

And this budget is only a conservative estimate!

If you want to connect all of Panujiu Island, it can be as simple as 1km. The southernmost point of Angka and Coro Island is more than 150 kilometers, which is equivalent to the distance from Wanghai to Hangzhou.

It is conservatively estimated that if the submarine tunnel that connects all of Panuji Island is to be built, the submarine part of the expressway must be at least 300 kilometers. If the project is contracted to the builders in China, the whole project will cost less than $60 billion.

Sixty billion dollars, good guys, this money is enough to build two more Penglai cities! Even if the future group of people has money, it is obviously not possible to follow this method.

However, in the future, Renren Heavy Industry has made breakthroughs in graphene technology. In the two fields of semiconductor graphene and high-strength nanomaterials, it can be said that no scientific research institution in the whole world is an opponent of the future human group materials science laboratory.

Among them, the graphene board applied to the future building is a breakthrough to lower the construction cost of the subsea tunnel. If a material that is tougher than steel can be used as the outer wall of a subsea tunnel, the progress of the entire project will undoubtedly be much easier.

At the beginning of April, in the form of open tendering, Futuristic Heavy Industries selected partners from the hundreds of construction companies around the world to register with Victoria Construction Company in Xiangjiang. The construction company once designed and constructed two submarine roads for Xiangjiang, and has deep knowledge of the construction technology of the immersed pipe method.

Considering that the immersed tube method is more suitable for the performance of graphene materials, Jiang Chen finally chose this company as a partner.

After the successful bidding, Victorian Construction Company immediately dispatched Wu Weiwei, an engineer in the Cross-Harbour Tunnel, to the new country to meet with future heavy-duty workers to discuss the construction of a subsea tunnel using graphene materials.

After flying off the island of Korro, Jiang Chen immediately invited him to the high-tech industrial park in Angola.

In the middle of the wide factory building, there is a semi-cylindrical archway about 12 meters wide and about five meters high. The walls of the archway are transparent, but the surface is not visible.

With Wu Weizhen walking to the side of this transparent archway, Jiang Chen took the hammer from the staff and slammed it on it.

Only heard a muffled sound, the sound echoed in the closed archway. Wu Weizhen looked down at the position of Jiang Chen’s hammer and shook his eyes in shock.

"This is our sample." Jiang Chen smiled and threw the **** in the hands of the staff, and clap his hands to look at Wu Weiwei, "the outer wall of the tunnel made of graphene material, ten times the strength of the ultra-molybdenum-nickel steel, longitudinal extension Sex is stronger than all metal materials, except that the problem of high temperature resistance has not been solved... Of course, there should be less chance of catching fire in the sea."

"A car accident may occur in the tunnel, and a car accident may cause a fire, even on the bottom of the sea." While stroking the outer wall of the graphene archway, Wu Weiyi whispered to himself and said, "But we can apply on the inner wall." Flame retardant, this is a good solution..."

After a pause, Wu Weizhen took back his hand and looked back at Jiang Chen and asked seriously.

“What is the cost of this graphene material?”

"On this archway, about one meter is about seven hundred dollars."

One meter seven hundred dollars, one kilometer that is seven hundred thousand dollars, this cost is simply cheaper than steel does not know where to go! If you can save such a large amount of money on materials, the construction cost of the entire project will undoubtedly be reduced several times!

Thinking of this, Wu Weizhen’s eyes on Jiang Chen suddenly became hot.

This graphene pipeline, Victorian construction company must find a way to get it! If you can get this high-strength, low-cost building materials, Victoria will undoubtedly gain strong market competitiveness in the global subsea tunnel construction market.

Not to mention the quality of the project, the cost alone is enough to kill countless competitors.

Victorian construction companies must build long-term strategic partnerships with future people!

Wu Weizhen has secretly made up his mind. When the trip ends today, he will return to the hotel where he stayed and he will call the boss and make sure that the interests are clear. If this business is done, this is a great achievement, promotion is not a dream, there is a wood!

The fiery gaze made Jiang Chen suddenly chill, and involuntarily opened the distance with this guy.

Hold the grass, this guy should not be so good...-

(After returning home, I caught a cold. I measured my body temperature yesterday, 38.1 degrees. After I finished the medicine, I slept, my head was dizzy. I have two chapters out of the code, I can’t figure it out... The promise of the outbreak can only After a day of delay, I am sorry, I tried my best to tt) (to be continued.)
