Doomsday Bunker Upgrade

Because all the parts and components have been prefabricated in advance, the workers only need to assemble them, so the construction of the heating hub did not take much time.

Including the time for laying the foundation, it only took two days to complete all the work.

After the installation of the heating hub was completed, Chen Xin originally planned to connect the pipes on both sides before starting the heating hub after the return well on the No. 7 Middle School was also completed.

After all, in addition to considering the problem of drainage, there is also the risk that a large amount of groundwater extraction may cause cavities in the rock formation and the formation of subsidence. Under the current situation of difficult natural replenishment of groundwater, it is necessary to avoid excessive extraction of groundwater as much as possible.

However, after consulting Professor Zhang's relevant knowledge, Chen Xin let go of his concerns.

Excessive pumping of groundwater will indeed cause cavities in underground rock formations, but this requires a long and continuous pumping. If it is only a short time and the pumping volume is not large, the impact will not be great.

Most of the geological collapse caused by groundwater extraction occurs in areas where groundwater is pumped on a large scale all the year round. In those areas, groundwater is used uncontrollably, and in areas with relatively poor water resources, precipitation is not abundant enough, and groundwater has been pumped for a long time. If it is not replenished, this will form an underground cavity and cause geological collapse.

As long as it is not drawn in large quantities and for a long time, it will not cause such serious consequences.

Moreover, although the geological structure of Linshi is complex, it is relatively stable, and there has been no geological disaster such as earthquake or collapse for many years.

Under such circumstances, Chen Xin did not hesitate and chose to start the heating hub.

With the operation of the heating hub, the underground hot spring water is pumped up with abundant thermal energy, and the heat is dissipated through the evaporative cooling equipment and then turned into cold water and discharged.

By design, this cold water should be piped to a return well and reinjected into the ground.

But since the construction of the backwater well has not been completed, the cold water can only be discharged naturally.

The stagnant water that Chen Xin feared would flow along the railway did not happen. Affected by the terrain of Linshi, which is high in the south and low in the north, the stagnant water was drained by the workers to the south of the railway station through pipes.

The south side of the railway station was originally the family area of ​​the railway station employees. It is only separated from the railway station by a wall and can be reached by crossing the railway.

Further south is a wasteland and a pond. This is a relatively low-lying place near the city. Although there is a large amount of snow cover, the terrain has risen slightly, but if you measure the altitude, it is still a low-lying area.

Therefore, after a water pipe is placed on the gully above the railway, and the water pipe is guided through the railway, it can be discharged here with confidence and boldness.

It is not only the cold water that has been dissipated, but also the stagnant water formed after the snow has melted.

However, the situation of water accumulation is not particularly serious, because while the heating hub emits heat to melt the snow, the ambient temperature also affects the melting of the snow, which causes the speed of the snow to melt is not very fast.

Just standing next to the snow pit, watching the heating hub at work emit a rolling heat wave, melting the surrounding snow little by little, and at the same time rising a stream of white "steam" around it, it is quite impressive. A feeling of being in the age of steam and feeling the beauty of heavy industry.

The reason why "steam" is generated is not that the temperature is too high, and the melting snow and ice directly turns into white steam, but that when the snow melts, a part of the water vapor evaporates into the air, and these small water droplets leave the supply. After the influence of the heating field of the thermal hub, the pre-cooling quickly condenses and turns into fine ice crystals.

Because the tiny ice crystals are too small and light, they do not fall to the ground, but are lifted into the air by the airflow, and naturally become white "steam".

Chen Xin stretched out his hand to wipe off the water vapor accumulated on the helmet, and looked at the gradually dissolving snow, and finally showed a satisfied smile on his face.

The speed at which the heating hub melts snow is of course not as fast as the speed at which the snow evaporates instantly when the heating equipment is turned on in the game "Frozen Age", but watching the snow melt into water at a speed visible to the naked eye, flowing and falling on the snow The bottom of the pit, after it became stagnant water and was pumped away by the pump, still gave Chen Xin a very strong sense of satisfaction.

This is what he made, bringing warmth back to the earth in this era, even though it is only a small place, it is still worthy of pride.

Thinking like this, Chen Xin walked down to the bottom of the snow pit, where the water had covered the feet of the power armor, but Chen Xin didn't care.

Because this is to facilitate the pump to pump water, it will accumulate so much, otherwise the water is too shallow, and it will be troublesome if the pump cannot absorb water.

Through the environmental monitoring of the power armor, Chen Xin can clearly know that the temperature around the heating hub has reached 27°C, but because the surrounding snow is more than ten meters high, it is almost flush with the heating hub. The area covered by the place is still only the snow pit, which has not reached the radius of 200 meters in Chen Xin's design.

However, as the snow continues to melt, the snow pit has begun to become wider at the top and narrower at the bottom. As long as it continues, it will become a big bell mouth, like a sea bowl.

Looking at the rumbling heating hub in front of him, Chen Xin thought about it and opened the lock of the power armor, walked out of the power armor, and took off his helmet.

The warm and vapor-rich air rushed towards him, causing Chen Xinqing to take a deep breath, letting the moist air inhale through his nose, filling his chest.

This feeling is really long gone!

This feeling of standing outside and breathing the warm air freely!

Chen Xin exhaled a long breath, and then looked up at the heating hub that stood like a tower in front of him.

Thanks to it, the air around here is warm and humid, just like the feeling of past summers.

Compared with the slightly dry and cold air in the shelter, the air quality here is not necessarily much, but it gives people a completely different feeling.

Just standing outside and breathing the warm, moist air is exciting enough.

After all, the whole earth is now a huge ice and snow hell. It is very rare and long-lost to be able to stand outside and breathe the warm air freely.

Feeling this kind of thing that was accustomed to in the past, but has become very rare now, after Chen Xin shook his head slightly, he also had a firm belief in his heart to promote it.

Let human beings return to the earth and get rid of their dependence on underground shelters. Chen Xin believes that relying on these heating hubs and planned energy towers, he will definitely be able to do it in his lifetime.
