A large number of transport vehicles entered from the driveway, meandering down, into the underground city, sending supplies, materials, and non-cold-resistant tree species from various forest areas in the south!Above the underground city construction area, rows of slogans were pasted on trucks and walls.

"Century plan, quality first"

"Guaranteed quality by management, progress by quality, and benefit by progress"

"Whoever builds the underground city will be the hero of the people of the Dragon Kingdom"

"In order to protect the people, to continue civilization, and to survive, I want to build a dungeon!"

The slogans, stained with the dust on the construction site, look gray, recording this era, and also showing the patriotic will of the Longguo project people.

"Director Xu, you're ready, do you want to go to the dungeon?" Zou Botao's old voice sounded.

This old man has been radiant these days, he is no longer the old man when he first met, and now he looks radiant.

Xu Qiu nodded and said, "Old man Zou is bothering you."

"Director Xu is working hard!"

After Zou Botao finished speaking, he said: "You are responsible for most of the work of the Emergency Bureau, and you are also responsible for making important decisions. I don't do much work, so I can often come to this dungeon to supervise the work. , management, etc.”

He introduced it and said, "Our Tiandu No. [-] Dungeon has a total of six departments."

"The first one is the engineering department. Construction preparation, production scheduling, and construction site management are all carried out by them."

"The second is the construction technology department. It is responsible for the detailed modification of the underground city drawings, the preparation of the construction plan, the measurement and setting out, the technical disclosure, the technical review, the management of engineering technical data, the testing experiment, the plan, the statistics, etc. It gathers people from all over the country. The strongest brain of engineers and designers!"

"The third is the Quality and Safety Department. It is responsible for the management of quality inspection supervision, evaluation, acceptance, safety supervision and civilized construction."

"There is also the Finance Department. Responsible for the monthly settlement of the project, the final settlement of the project, financial management, cost accounting, etc."

"The key is the material supply department. They are in charge of the material procurement, management, distribution, equipment scheduling, maintenance, repair, etc. of the entire dungeon."

"The last one is the general office. The medical care, canteen management, living facilities, documents, and coordination with other dungeons and the surface of the dungeon are all the work of the general office." Xu Qiu nodded, following Zou Botao, Along with a bunch of excited engineering executives, enter Dungeon One.

This was the first time he visited 50 Meters Underground after the construction of the dungeon started to inspect the construction.

What does this underground city look like now?

Xu Qiu was looking forward to it.

Meanwhile, Berry Country.

In a private manor, Yoder, the deputy commander, and Fran, the speaker of the House of Representatives, are gathering in the restaurant on the upper level of the manor, drinking red wine.

"The huge wall of wind and snow in Berry Country is the first layer of protection."

Joad spoke slowly, with a confident smile on his face.

"Ain and his group of scientists can't cover up the facts no matter how extravagant they say. I am the leader of Berry Country, and I know better than them how poor Berry Country's construction capabilities are!"

A hint of sarcasm flashed in Joad's eyes.

Just a few years ago, he ordered the construction of a border wall along Mexico's border with Berries.

In fact, this thing is a bunch of iron pillars lined up together, similar to the iron gates in prisons, only thicker and taller.

However, for the 20-kilometer border wall, the Chinese engineering team asked for [-] billion dollars.

Months after construction, these border walls are already rusting...  

Even, there are quite a few road sections where the border wall collapsed!

Such a construction ability, but also build a giant wall of wind and snow?

protect who?

It's just paralyzing the people!

Yoder, the deputy commander and other high-level officials will not wait for the fortress of Berry Country to be built and wait for the giant wall of wind and snow to protect them.

"Although we can't build a super dungeon like Dragon Kingdom, there is still no problem in building a small doomsday shelter. After all, we are Berry Kingdom! Our technology and machinery are number one in the world.

Fran chuckled.

In fact, the design of the doomsday shelter that led Yoder had already begun.

In other words, any rich man has such a way out, and it has another name, "Underground Noah's Ark".

Unlike other shelters,

Yoder's underground Noah's Ark is extremely luxurious, and it was transformed from the underground silo of the Atlas F carrier rocket in Berry Country.

The entire underground Noah's Ark has a depth of 53 meters and a thickness of 7 meters. The construction cost of just one floor is about [-] million yuan.

Inside, there are a total of ten floors, and there are two additional large floors at the bottom.

There are many suites in the underground Noah’s Ark. The area of ​​the suites is basically more than [-] square meters. There are kitchen, dining room, living room, etc. The bedroom will also be equipped with a whole wardrobe, and the huge electronic display screen will be used as a window. .

It can display the beautiful scenery of Bali, Niuyue, and other places, and even natural landscapes such as beaches and forests, simulating the scene in the outside world.

In the later stage, Yoder intends to sell these suites, and the price of a set is expected to be more than 5 million yuan.

Of course, in addition to these, libraries, cinemas, swimming pools, schools and medical centers will also be built in the underground Noah's Ark.

Also, there is an indoor farm for growing enough vegetables, lots of fish and more.

And most importantly, the underground Noah's Ark will also contain a complete life support system and power supply facilities, etc., and the food stored inside can supply two hundred people for 80 years!The deputy commander said flatteringly: "Master Commander, you are indeed foreseeable. The underground city needs to choose a place with good engineering geology and hydrogeological conditions, and your manor just meets this requirement!" Yoder smoked a cigar, his eyes blurred ,Feel comfortable.

That's why he bought the manor back then.

Unlike others who bought manors with designers and architects, Yoder called several geologists to conduct accurate and complete geological surveys for each property.

Finally chose here.

The soil layer in the manor is very thick, has a strong bearing capacity, and the soil quality is also uniform. There are no unfavorable areas such as backfill layer, silt layer, and quicksand.

Moreover, the rocks under the manor are uniform in lithology and simple in structure, with a large number of hard and thick rock formations.

The manor just avoids faults, broken zones, earthquake zones and unstable slopes.

It can be said that this is one of the most suitable places in Berry Country to build an underground Noah's Ark.

Joad drank a glass of red wine and said, "In the underground Noah's Ark, the internal temperature, temperature, humidity, cleanliness, noise intensity, lighting intensity, indoor color and other aspects have been taken into consideration."

"A suitable air environment is mainly guaranteed by a perfect ventilation design; the proper use of sound insulation and sound absorption measures can control the noise intensity within the allowable range. Architectural processing such as the integrity and change of internal space combinations, the unity and texture of materials Contrast, richness and harmony of indoor colors, etc., all help to create a good internal environment and eliminate the adverse physiological and psychological effects of the underground environment on people..."

"Our underground Noah's Ark may not be as big as the underground city of the Dragon Kingdom, but we have all the living facilities and life support systems!"

"Even if the giant wall of wind and snow falls, we can still survive 80 years underground!"

80 years...

It is enough.

Yoder is already 74 years old, and the person who can sit in the leadership position of Berry Country will not be too young.

Calculated, Yoder doesn't have too long to live, including Fran, the deputy commander and others, at most they will live another 40 years. The food supply for 80 years is enough for them to end their lives.

As for future generations, the survival of the next generation.

who cares!

Holding a glass of red wine, Yoder walked to the window and looked at the mighty construction team outside.

No matter what the world is like, it is enough for them to survive.

Dragon Kingdom, Tiandu No. [-] underground city.

Da da da.

The sound of iron chains and gears turning.

The purely mechanically driven elevator took Xu Qiu and others to the underground city at a depth of 50 meters.

This is a top-notch machine made from the subspecies of extremely cold bainite steel used to produce extremely cold steel rails—the subspecies of extremely cold steel. Even at a temperature of two hundred degrees below zero, the elevator can still operate normally.

Everything in the dungeon, from the beginning of its construction, has served to fight against the extremely cold era.

This is true from the shaft entrance of the dungeon to the delivery entrance.

Especially the load port.

In fact, there is a node every 20 meters for the two-kilometer-long spiral carrying entrance.

And this is set for the insulation layer. After the arrival of the extreme cold era, the delivery entrance will be completely closed. Every 20 meters, a heating layer, a thermal insulation layer, and a thermal insulation layer will be installed, and a large amount of insulating gas will be filled in the middle. , Material!

This will ensure that even if the surface is extremely cold at minus two hundred degrees, it will not pass through this huge entrance and affect the overall temperature balance of the dungeon.

click.

With the gears stalled, the elevator stopped at the shaft entrance to the dungeon.

The alloy door opened, Xu Qiu stepped out, and the sound of rumbling construction came over his face!

This scene is enough to shock anyone! !

All kinds of tower cranes are distributed on the construction site of the underground city, such as track type, fixed type, wheel type, crawler type, etc.

Excavators, forklifts, etc. are used for production to excavate the soil, and then transport it to the surface from the two-way six-channel, and send it to the place where the soil blocks are specially piled up.

Conveyors and elevators are running with loud noises, and the smell of engine oil and the smell of opened soil fills the nostrils.

The three-dimensional high-bay warehouse storage system is also moving materials.

The gray-faced workers wearing hard hats are doing more delicate work.

For example, manual pallet trucks reload materials, unload goods, measure, etc.

Zou Botao introduced: "Director Xu, we are now in a transition zone."

He pointed to the rear, where the truck loaded with lush trees was driving, and said: "Our west is the planned area of ​​the forest ecological area. This is an area that has been opened up independently of the construction of the underground city."

"Therefore, our underground city construction and forest transplanting plan can be carried out simultaneously without any impact on each other."

Xu Qiu nodded.

Indeed, except for the two-way six-lane that shares the loading entrance with the forest transplanting plan and the material transportation of the underground city,

The forest transplant plan will not affect the construction of the dungeon at all.

Zou Botao pointed forward again,

In the dungeon construction area, there is no dust as imagined.

He said: "In order to avoid the dust problem and reduce the physical damage to the construction workers, we have taken three measures in total."

"The first is bionano-film dust suppression technology."
