He turned his head and said to the Prime Minister: "Master Prime Minister, I don't think we can wait any longer, let's give an order, the whole country will fight against the end..."
The Prime Minister of Sakura Country squinted his eyes, exuding coercion.
dong dong dong.
Ying Shi chu knocked on the table leisurely.
The entire meeting hall was extremely quiet, and everyone's hearts were suspended, for fear that the prime minister would lose his temper.
The Prime Minister of Sakura Country stood up and walked to the window.
He opened the window and stood with his hands behind his back, feeling the harsh summer wind from the streets of Tokyo...
Yes, the biting cold summer wind!
On the street not far away, there are lovers holding hands to build snowmen.
Logically speaking, at such a temperature, it is almost impossible for snow to accumulate, and it will melt into rainwater in mid-air,
However, this blizzard was too weird, and it was too unreasonable.
The speed of snow melting cannot keep up with the speed of falling!
This country, this group of people, will be frozen into... ice sculptures in the future?
After a long time, the Prime Minister of the Sakura Kingdom spoke, sighed deeply, and said, "In that case, then, I will leave this arduous task to Your Excellency."
Saito said with a vicissitudes of life: "Leave it to me, Prime Minister."
He issued several orders in succession.
"In Sakura Country, all architects, climatologists, scientists, architects, etc., will attend the meeting at two o'clock sharp this afternoon. The topic of the meeting is: If the sun goes out, what can we do to save ourselves?"
"At the same time, an early warning is issued to the people of the entire Cherry Blossom Country. Overseas students, tourists, etc., should return to the Cherry Blossom Country as soon as possible. The whole country will work together to prepare for the end."
"Thirdly, call on the literary and art circles to create a batch of literary and artistic works as soon as the doomsday comes, the Cherry Blossom Country saves the people, and leads mankind to rebirth from the disaster, so as to enhance the confidence, dedication and cohesion of the people of the Cherry Blossom Country
[July 7th, the fifth day of the Dragon Kingdom Dungeon Era, the entire Sakura Kingdom entered a wartime state. ] [Since the Dragon Kingdom, the Cherry Blossom Kingdom is the first country to announce that the whole country has entered a state of disaster relief! 】
Dragon country.
The vigorous demolition movement is going on in full swing across the country.
At this moment, Xu Qiu, Zou Baitao and others are discussing the construction plan of the nuclear power train.
The dungeon is being built, and the demolition operation is also going on,
At this time, it is just in time to finalize the construction plan and route of the entire ring-country train.
There are a thousand underground cities across the country, and it is not a small project to connect all these places to the path of nuclear-powered trains.
Xu Qiu, who was seated at the top, took a sip of tea and watched as the director of the Cold Region Environment and Engineering Research Institute of the Longguo Academy of Sciences and the director of the Longtie Northwest Academy of Sciences Research Institute quarreled over the setting of a site.
At this moment, a mechanical electronic synthesizer sounded.
System: "Congratulations, the initial plan for global fraud has been completed, and the people of all countries have begun to waver in their doubts about the doomsday."
"Get new incentive rewards: master-level architecture, mechanics knowledge! Nuclear power train track laying route map!"
A lot of architecture and mechanics knowledge poured into Xu Qiu's mind,
Building structure, building special structure, construction drawing design, etc., as well as art, light and shadow, shape, color...
Gears, brakes, nuclear power plants, internal combustion engines, transmissions and more...
Xu Qiu gave a jolt, and instantly regained his energy.
What is really missing...
Now the construction of the dungeon has not entered the white-hot stage. Generally speaking, the whole country is digging holes, and the construction of the dungeon has not really started yet.
At the moment, the most urgent issue is actually to finalize the matter of the nuclear-powered train first.
And the master-level knowledge of architecture and mechanics came in handy! !
"Everyone, don't discuss the route issue yet." Xu Qiu interrupted everyone and said.
In his mind, he already had a perfect track laying map for nuclear-powered trains, and the most urgent task was to solve various problems in the track laying stage.
Compared with building a nuclear-powered train, laying a track around a thousand underground cities across the country is a protracted, time-consuming and labor-intensive task.
The research director of the Northeast Permafrost Research Institute said:
"We still need to study the basic characteristics and distribution characteristics of permafrost after the end of the day, as well as the types of permafrost along the route, the distribution law and formation conditions of cold phenomena, and the relationship between the structure and water content of various permafrost!"
The Academician of the First Survey and Design Institute of Northwest Railway said: "When you meet mountains, you open mountains, and when you meet water, you build bridges! This is what we did when we designed the Qinghai-Tibet Railway. Embankments, culverts and other facilities have been divided into 23 test sections!"
Xu Qiu said in a deep voice: "This time, it's not as simple as a Qinghai-Tibet Railway. It's a nuclear-powered dragon that encircles the whole country! Its mileage is beyond everyone's imagination!"
Zou Baitao asked: "Director Xu, the chassis of the nuclear-powered train you designed will heat the ice and snow on the track with nuclear energy, so there is a problem..."
"The soil frozen layer that was originally frozen all year round will continue to thaw and heave due to the passing of the train, which will cause double damage to the roadbed and track!"
Xu Qiu nodded, he thought for a moment, and said:
"There are two measures I can think of."
"Depending on the material or the design structure of the subgrade, the thermal resistance is increased and the heat transmitted to the permafrost of the foundation is reduced."
"As well as cooling the permafrost layer of the foundation and maintaining the stability of the permafrost foundation, thereby ensuring the stability of the engineering track."
The academician of the First Survey and Design Institute of Northwest Railway couldn't help asking: "How to realize it?"
"These problems are too unsolvable. Even the Qinghai-Tibet Railway has never encountered these problems!"
Everyone looked embarrassed.
Permafrost frozen all year round...
To build a durable, stable, and workable track on such land, and to run trains on it...it's incredible!
Many people present have designed different generations of high-speed rail and maglev trains, and some of them are even world-renowned mechanical construction masters!
They admitted that they were amazed when they saw the design drawings of the nuclear-powered train!
However.…
When they really started laying tracks and designing nuclear-powered trains, they realized that there are too many problems in reality!
How to ensure that the roadbed will not be damaged by freezing?
How to prevent the damage to the track caused by thawing and frost heaving?
Xu Qiu closed his eyes, tapped the teacup with his index finger, and his mind was running fast.
Zou Botao and others held their breath, not daring to interrupt Xu Qiu's train of thought.
After a long time, Xu Qiu opened his eyes.
Everyone's spirits were immediately concentrated.
"Everyone, I have thought of seven solutions."
"Seven?!"
Zou Botao looked over in surprise.
They thought that Xu Qiu was just thinking of a solution, and whether there would be a result was another matter.
As a result...Xu Qiu directly gave seven solutions!
Xu Fu, an academician who once designed the Longguo standard EMU, and the third-generation Fuxing, said: "Director Xu, I would like to hear the details!"
Ji Chengping, the designer of Longguo's new CRH1A, the proposer of the magnetic levitation + true low-altitude mode, and the founder of Longguo's maglev technology, stood up: "I hope Director Xu will enlighten me!!"
Xu Qiu didn't hold back, took a sip of tea, moistened his throat and said loudly:
"The first is to determine the reasonable height of the roadbed. This is equivalent to covering the frozen soil layer of the roadbed base with an insulating layer to prevent the extreme cold on the surface and the frozen soil layer below from directly causing damage to the roadbed."
"Second, the flake ventilated embankment structure."
"This method may be familiar to some engineers and designers involved in the design of the Qinghai-Tibet Railway. That is to cover the embankment with crushed stones, which can play a role in thermal regulation."
"In the cold sunset era, due to the high density of cold air, under the action of its own weight and strong wind, the cold air in the flake layer will be squeezed away, and the cold air can enter the subgrade base more easily, thus protecting the permafrost layer!"
"As long as the permafrost continues to thaw, then we don't need to consider the damage to the tracks and subgrades caused by the alternation of cold and heat. We only need to develop materials that are extremely cold-resistant, and we can perfectly solve this problem." Eyes of Zou Botao and others one light.
That's right, instead of considering the alternation of cold and heat and extreme cold at the same time, it is better to actively keep the subgrade extremely cold to prevent damage to the subgrade due to heat melting.
Two problems become one problem, and it is much easier to solve!
"It's...exquisite!" Zou Baitao praised sincerely.
"What else? What else?" The academician of the First Survey and Design Institute of Northwest Railway has a thirst for knowledge in his eyes.
Xu Qiu looked wisely and said, "The third is the thermal pile subgrade structure."
He tore out a piece of paper, drew a few arrows on it, and marked the names of various mechanical parts.
"Look, the thermal pile I designed is a heat conduction system of vapor-liquid convection and circulation! The top of the thermal pile is a sealed tube filled with ammonia, freon, propane, carbon dioxide and other substances!"
"The upper section of the thermal pile pipe is a condenser, and the lower end has an evaporator, and the middle is transitioned with a heat insulating material, which is set as an adiabatic area."
"When the lower end of the heat pile absorbs heat, ammonia, freon, propane and other substances are converted from liquid to gas, and then rise to the condenser."
"Thus, the heat dissipates through the condenser, ammonia, freon, propane and other substances are liquefied from gaseous state to liquid state, and flow back to the lower end of the heat pile under the action of gravity!"
"Under such a cycle, the temperature of the surrounding permafrost will continue to drop. At the same time, the cold storage of the permafrost itself will also increase!"
"This measure can improve the thermal stability of the permafrost, thereby ensuring the stability of the roadbed!!"
Xu Fu suddenly stood up, this old man who designed the third-generation Fuxing was excited.
"Brilliant...fantastic design!"
Zou Botao was also amazed.
The principle behind this design is actually very, very simple.
Who doesn't know that the vaporization of ammonia, freon, propane and other substances will absorb heat?
However, no one thought of Xu Qiu's thermal pile device!
This kind of device has a very simple structure and principle, but such a simple combination has played a role in perfectly fitting the current pain point!
"Director Xu, keep talking!" Xu Fu, who had gray eyebrows and beard, began to look forward to the next measures.
Xu Qiu said calmly: "Fourth, lay the roadbed structure for the heat insulation layer."
