Douluo See You For a Long Time

For a civilization with no shortage of energy, the speed of construction will be very fast. As time goes by, after ten years, the highway from the land to the ocean has been completely built, including the highway on the surface and the highway underground. Utilization facilities have also been built next to the underground highway. A super railway powered by both magma energy and Stirling engines.

When designing this railway, the designer considered that when a large amount of materials and people need to be transported, the trains running on the railway need to be very wide.

In this case, the distance between the rails is enlarged to a considerable extent.

In fact, humans living on earth can find that the distance between railways in reality is actually somewhat narrow through careful observation. This can be seen in the shape of today's railways and trains. Train carriages are much wider than track spacing. In the earliest times, the train carriages were not like this, but were about the same width as the track. This change occurs now, obviously because the vehicles have to carry out this kind of work in order to load more goods and passengers. transformation.

This standard was actually passed down from the spacing between tracks in the ancient Roman era, and people at that time did not consider how powerful the future trains would be when designing the tracks. What a wide track it can take on. In contrast, people in this world experience technological development at the speed of a technological explosion. When looking at problems, we tend to look more towards the future. Some technologies may not be very suitable for now, and some designs may even affect the speed of industrial development now, but if they are suitable in the future, Then it is likely that relevant designs will be adopted.

Human beings in this world also had the same idea when designing railways. When they first designed it, it was actually quite difficult to make a train that could span such a huge span of track. The materials science at that time was still not very advanced. It was not as developed as it is now. If the train is so wide, there may be shaking in the middle. If too much cargo is loaded, the carriage may even be deformed. So much so that the car chassis at that time had to be very thick.

But with the advancement of technology and materials science, cars have begun to become stronger. Even if it is above magma, Mercedes-Benz will not soften and deform due to high temperatures. Now the track spacing has become appropriate, and this design also makes it easier for them to transport large amounts of cargo to ocean locations.

This railway line has almost become a lifeline. After all, the cost of transportation by rail is much lower than the cost of transportation by entry.

After all, if you drive on the road in this world, you will consume energy, and the car must be filled with hydrogen tanks or biogas tanks. The Stirling engine in the car is then heated by the high temperature of combustion and the high-temperature water remaining after combustion, and the prices of these fuels are quite expensive.

In contrast, the train travels directly on top of the magma and uses the temperature difference between the magma and the air to provide power through a Stirling engine. It requires almost no additional fuel to move forward, and the cost is much lower than transporting by road. Don't know where to go. It is after realizing this gap that humans in this world built railways, which are much more difficult than roads.

After all, they need to estimate the location of the magma river and the water level height of the rivers along the river to ensure that the location of their railway construction will not be engulfed by magma. They also need to create a concrete-like structure to support it above the magma to ensure that it will not be engulfed by magma. To be melted from below, it is necessary to ensure that a foundation is laid below the magma so that the pillars supporting the rails will not deform or fall during the flow of magma.

These are all epic projects for human civilization in this world, and they have successfully completed these epic projects one by one, which can be said to be quite successful for them.

A large amount of ore was transported to the ocean along this lifeline, and construction in the ocean developed in this way. Although when large machinery needs to be built in sea water, it cannot be supported on the ground like on land. The deep sea is extremely deep. If production is carried out on the seabed, the huge pressure is normal and humans cannot bear it.

However, humans in this era also discovered some advantages of the seabed.

In the ultra-high pressure environment under the sea, if some metals are cast, metals with a higher density than ordinary metals and a stronger internal crystal structure will be produced. Even the high temperature resistance of these materials will be relatively improved.

At present, they have also begun to try to make some machinery to process objects in deep water. High-strength and high-pressure materials are now widely used in drill bits. And drills are also quite useful equipment for people in this world.

After all, they live underground all year round, and they must use drills to dig their own caves and tunnels in caves.

But after getting under the ice, he still couldn't escape the fate of digging holes.

Under the ice, they must use their own drills to dig out a piece of the ice cap above, introduce air into this area, and then create a suspended platform suitable for their own survival under the dome.

The living pattern is actually not much different from that in an underground cave. The difference is that what they rely on here is not the high temperature provided by the rivers along the river, but the entire warm ocean, so the direction of the development and cave can be arbitrary.

Humans can dig in whichever direction they want according to their own plans. The biggest benefit of this is that they can regularly divide their living areas into hexagons during the digging process. area. In other words, it is a triangular area. The regular distribution of these triangular areas makes every road orderly, and urban traffic is much easier to handle than before when complex terrain had to be considered in underground caves.

These are all projects they have carried out near the sea. With the increase in population and the advancement of technology, the area occupied by humans is further expanding, heading towards the depths of the ocean. This world is somewhat similar to the earth. The sea surface is also extremely huge, occupying most of the entire planet.

And the ice surface is like a dome. It's like the continental plates on Earth. The characteristic of each plate is that it is thin in the middle and on both sides. And now humans only live on the edge of the plate closest to the sea. Their current development method is to continue to develop from the edge to the center.

During these years of survival, they found that the edges of the plates were relatively fragile. Ice blocks will also collide and squeeze each other during the ocean current activity below. The edge of the ice surface close to the continent is relatively stable, because the continent is softer than the ice surface. During the collision and squeeze process , some silt-like structures can be generated for buffering, and the probability of ice breaking is not high, which means that the probability of an earthquake is not very high. But on the side closer to the ocean, the edge of the ice sheet often cycles through the process of breaking and freezing. The location on that side is equivalent to the volcanic earthquake zone above the earth. If someone lives there and builds his base under the ice cap there, he will face earthquakes every now and then, which is about the same frequency as earthquakes on Earth. But living under the ice cap, if an earthquake occurs, the casualties will be much more tragic than those of humans living on the ground. It is very likely that all people in an underground city will be completely buried underwater.

The frequency of disasters is not much different, but the degree of disasters is very different. Therefore, plate edges similar to volcanic and seismic zones in this world are absolutely unsuitable for survival. Even if there may not be an earthquake there for decades, if there is an earthquake, it is likely to lead to ecological extinction.

To be precise, this kind of earthquake cannot be called an earthquake. It should be called an ice earthquake. In order to survive in a more stable area, humans chose to move towards the center of the ice sheet after observing earthquakes occurring on the ice in the distance. . The thin structure around the middle and back determines that the center of the plate is quite stable. Even in a collision with other plates, the center is the least likely to break. In fact, the difficulty of surviving there is not much different from that of surviving in the surrounding areas.

It is nothing more than digging an area downwards as an area to carry water. Another advantage of doing this is that there is a ground similar to that in a cave.

It may sound a bit difficult to understand. But by analogy, you can understand by digging caves. Although the oceans in this world are covered by huge glaciers, there is still sea level. The ice surface basically floats above the sea surface. Sea level therefore lies at a certain level above the ice sheet. That is the location where the altitude is 0. Human beings live on this flat interface.

To survive on the edge of the ice, all you have to do is knock off the excess ice above your head, and then leave enough air above the water surface, so that you can establish a survival base where the ice is underwater.

It is necessary to dig the cave along the horizontal plane toward the inside. After the cave is successfully excavated, the horizontal interface can be clearly found inside the ice layer. As long as a hole is drilled above the ice surface to allow air to circulate and form a connector-like structure, it can ensure that the horizontal height of all areas under the ice surface is the same. After knowing this, surviving in the ice is actually easier than surviving in the water. When the water level is the same, this is somewhat similar to building a water conservancy project on land. Digging canals guides the water in the ocean to flow to the desired location on the ice surface. At this time, there is no need to make any floating islands. You only need to dig inside the ice and dig out caves higher than the water level, which can be used as land for people to live in the ice. Those places lower than the ice are rivers and lakes, and among rivers and lakes are Humanity's industrial base.

When arranging an industrial base in the ocean, it is necessary to make hollow metal boxes so that the base can float above the water. But here, the base can completely sink to the bottom of the water and take root directly on the ice surface of the bottom of the water. , which is almost the same as being in a cave, except that the water here is much easier to obtain than in the cave, and the living environment is much more suitable for humans than in the cave.

When designing these cities in the ice, road traffic construction will also be taken into consideration.

Tunnels and a river will be specially set aside for the construction of rail trains.

The surface of the water can serve almost the same purpose as magma. As long as the ventilation shaft above blows enough cool air. This ensures that these vehicles can run almost continuously within a sufficient temperature difference.

With enough energy, such cities are being developed one by one.

The icy cold wind kept blowing down from the scenery above the head, while the engineer drove the water suspension engineering machine driven by the Stirling engine, looking for the book garden www.zhaoshuyuan.com, which was like an excavation on a speedboat mounted on the water. Like a machine, he quickly arrived at the location of the cave he needed to dig and rest. Then he inserted something like a hook machine on the ice and cut out huge ice blocks one after another. In order to ensure that his speedboat on the water could maintain Balance, when working, it will stretch out four mechanical groups to grasp the underwater ice surface. These mechanical groups are made of high-temperature-resistant materials developed by humans in this world. Even in the water, they will not Melting and softening, these machines can be stably fixed. This is not how giant tunnels between cities are built, those are tunnels excavated by TBMs.

This kind of small construction machinery is more used to build residential houses and residential buildings. To be precise, it should not be residential buildings. There is no shortage of space in the world, so buildings like buildings have not been designed. Everyone They all live on the first floor, and there is a river in the room, ensuring that each family has enough water.

The water consumption of people in this world is much greater than that of people on earth. Some people have even taken to sleeping in the water. Because only when you are wrapped in water and water vapor in that environment, the temperature environment around you is the most comfortable for you to rest. So the beds people sleep on in this world are often connected to a pool, a diving pool connected to the flowing water. As long as you don't sleep on your stomach, you won't choke on the water while sleeping. And the function of pillows in this world is But it is much more important than on earth. After all, if you sleep on your side without a pillow, if the water surface fluctuates to a certain extent, you may choke on the water. This can have a considerable impact on the quality of your sleep.
