Installing the geothermal generators was no easy task, because it required placing many pipes into the Lava Passage to pump water into it.
The pressure inside the Lava Passage was immense, so before lowering anything down, they first had to release some of the pressure inside the passage to prevent it from suddenly shooting up through the pipes! This made the construction extremely difficult.
So far, one Lava Passage in this shelter had been surveyed. It was about two kilometers from the shelter's main structure.
Even if it really erupted, it would not affect the safety of the main shelter.
Relieving the pressure in the Lava Passage was extremely dangerous, but to the construction crew at this point, those dangers were as good as nonexistent! When digging meant survival and not digging meant immediate death, they had little chance to choose—and no need to choose!
At the geothermal power station construction site, a large group of slaves and a group of vagrants were working hard to expand downward according to the Engineering Department's requirements.
This was a somewhat troublesome construction project, and its construction methods were completely different from those used for the shelter's main structure.
Over there, whenever they excavated some space, they immediately began assembling Prefabricated Parts to keep it from collapsing. Then they reinforced the edges of the space with steel bars and poured concrete.
Only after the concrete had mostly dried would they continue digging downward.
It looked as though this wasted a great deal of time, since they had to wait for the concrete to dry, but in reality, no time was wasted.
They could continue expanding the underground space horizontally. By the time an entire level had been nearly excavated, the places where they had first poured concrete would have basically dried completely.
