Chapter 373

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

Taking into account the time of laying the foundation, we finished all the work in just two days.

After the installation of the heating hub, Chen Xin originally planned to connect the pipes on both sides and start the heating hub after the water return well on the side of the seventh middle school was also completed.

After all, in addition to the problem of drainage, there is also the danger that a large amount of groundwater extraction may cause rock cavity and collapse. In today's situation that it is difficult to replenish groundwater naturally, we should avoid excessive groundwater extraction as far as possible.

However, after consulting Professor Zhang for relevant knowledge, Chen Xin put down this concern.

It is true that a large amount of groundwater extraction will cause underground rock cavity, but it will take a long time and continue to extract a large amount of groundwater. If the amount of groundwater extraction is small in a short time, the impact is not big.

Because the geological collapse caused by groundwater extraction mostly occurs in the areas where groundwater is extracted on a large scale all the year round. The uncontrolled use of groundwater in those areas, coupled with the relatively poor water resources, the precipitation is not rich enough, and the groundwater is extracted for a long time and can not be supplemented, which will form the underground cavity and cause the geological collapse.

As long as it is not a large number and a long time of extraction, 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.

In this case, Chen Xin did not hesitate to start the heating hub.

With the operation of the heating hub, the underground hot spring water is pumped up with abundant heat energy, and the heat is emitted by the evaporation and heat dissipation equipment, and then it becomes cold water to be discharged.

According to the design, the cold water should be piped to the return well and then re injected into the ground.

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

Chen Xin's worry that the water would flow along the railway did not happen. Affected by the high terrain in the South and low terrain in the north of Linshi, the water was drained to the south of the railway station by workers through pipes.

The south of the railway station used to be the family area of the railway station staff. It is only separated from the railway station by a wall, and can be reached by crossing the railway.

Further south, there are wasteland and a pool. This is a relatively low-lying area near the city. Although there is a lot of snow cover, the terrain has slightly increased, but if the altitude is measured, it is still a low-lying area.

So after using a water pipe to stand on the gully above the railway and guiding the water pipe across the railway, you can safely and boldly discharge it here.

It is not only the cold water after heat dissipation, but also the accumulated water after snow melting.

However, the situation of water accumulation is not particularly serious, because the heating hub emits heat to melt the snow. At the same time, the environmental temperature also affects the snow melting, which leads to the snow melting speed is not very fast.

Just standing next to the snow pit, watching the heat wave from the heating hub at work, melting the surrounding snow a little bit, and at the same time rising white "steam", it really makes people feel the beauty of heavy industry in the steam age.

The reason why "steam" is produced is not that the temperature is too high, which makes the melting ice and snow directly turn into white steam, but that when the snow melts, part of the water vapor evaporates into the air. After leaving the influence range of the heating field of the heating hub, these small water droplets condense rapidly and become small ice crystals.

Small ice crystals are too small and light to fall to the ground. Driven by the air flow, they rise into the air and naturally become white "steam".

Chen Xin reached out to wipe the water vapor from his helmet. Looking at the melting snow, he finally showed a satisfied smile on his face.

The speed at which the heating hub melts snow is certainly not as fast as the speed at which the snow evaporates as soon as the heating equipment is turned on in the ice age game. However, watching the snow melt into water at the speed visible to the naked eye, flow and fall at the bottom of the snow pit, and then be pumped away after it becomes stagnant water can still give Chen Xin a very strong sense of satisfaction.

This is what he made, in this era will be warm back to the earth, although it is only a small place, still proud.

Chen Xin walked down the bottom of the snow pit, where the water has gone beyond the feet of the power armor, but Chen Xin didn't care.

Because this is for the convenience of the pump pumping, will let it accumulate so much, otherwise the water is too shallow, the pump can not absorb water also trouble.

Through the environmental monitoring of the power armor, Chen Xin can clearly know that the temperature around the heating hub has reached 27 ℃. However, because the snow around the heating hub is more than 10 meters high, almost equal to that of the heating hub, at present, the only area covered by the heating site is the snow pit, which does not reach the radius of 200 meters in Chen Xin's design.

However, with the continuous melting of snow, the snow pit has begun to become wide at the top and narrow at the bottom. As long as it continues, it will become a big trumpet, like the shape of a sea bowl.Looking at the booming heating hub in front of him, Chen Xin thought about it, opened the lock of the power armor, came out of the power armor, and took off his helmet.

Warm and rich in water vapor, let Chen Xin can't help but take a deep breath, let the moist air along the nose into the body, full of his chest.

I haven't seen you for a long time!

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

With a long breath, Chen Xin looked up at the tower like heating hub in front of him.

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

Compared with the slightly dry and cold air in the shelter, the air quality here is not as good as it can be, but the feeling is quite different.

Just standing outside and being able to breathe warm and humid air is enough to make people excited.

After all, now the whole earth is a huge ice and snow hell. It's very rare to be able to stand outside and breathe warm air freely, which has been a long time since.

Feeling this kind of thing, which used to be common in the past but has become very rare now, Chen Xin shakes his head slightly and has a firm belief in promoting it.

Chen Xin believes that relying on these heating hubs and planned energy towers, he will be able to do so in his lifetime.
