There are no bricks to use now, but stones can be used instead, and ancient wells do the same.

The location of the well is very important, it is generally chosen next to the water source, and the terrain is lower. Su Yang pondered for a moment, and then drew a circle with a diameter of about one meter a few meters away from the side of the salt spring.

Stick a wooden stick into the ground and pull the rope tied to it to walk around, which is a standard circle, a humanoid compass.

"Bring me the rake." Su Yang took the tool and personally soiled, this is actually a ritual.

After shoveling the earth a few times, it was handed over to a strong warrior to dig the earth, and the well could only be dug by one person, because the mouth of the well was so large that there was no room for two people. Two or three people are enough to help.

However, in order to speed up the progress, he is ready to change people at any time, but the number of people in the team is still too large. Simply dig three wells at the same time, form a triangle, and enclose the small hillside in it.

At the same time, he divided half of his warriors to go out hunting, and had to solve the problem of food, and after the salt well was finished, they would not leave for the time being.

The person who digs the well only needs to shovel out the soil, and the person who helps next to him will be responsible for transporting the soil to the side, and gradually a pit will appear, and the person will stand in the pit and continue to dig, until a hole will appear later, and as the hole deepens and advances, the human body will slowly sink to the ground, not over the waist, not over the head, until the person can no longer see. But the entrance to the cave has always maintained the size he demarcated at Su Yang's request.

Whether the well water is sufficient or not has nothing to do with the size of the hole, but the bigger the hole, the more tiring it is to dig, so it is enough to have a well that is not big or small.

At this time, the person who had already been replaced and continued to dig in the deep pit slowed down, and it was necessary to hang the bamboo bag down, fill it with dirt and then lift it up. The progress of the three wells is about the same, and the depth of the household well is generally about four meters, and the accumulation is shallow surface permeable water, and the amount of water is limited and easy to drain, which belongs to shallow wells.

In the afternoon, the well near the spring began to come out, and it was almost like standing in the mud water to continue digging, but at this time it could not be stopped, and if the time was delayed, waiting until the well was full, it would cause trouble for the next day. Now there are no pumping machines, only manpower.

When a soldier was tired, he replaced the next one, and kept carrying the dirt up, and the further he dug down, the less impurities there were in the soil, and although there was stagnant water, the speed increased. Large chunks of earth were hoisted up and dumped.

"Sue, there's water out of here too."

He hurriedly went over to see that another well had also come out of water, and it had been dug about three meters deep. After a while, the third well also came out of the water.

At first, the well was getting more and more water, which caused problems for the digging, and it was almost four meters deep enough to stop. But if he wanted to dig deeper and get to the bottom, he had to use clay pots to bring the water up.

It's a pity that I didn't think of digging a well before, otherwise it would save a lot of effort to get a rotating roller and use a rope to lift.

The clay pot is constantly being hung down, filled with muddy water and then hoisted up, all by manpower, tired to replace people, so that after half an hour, you can continue to dig.

In the evening, the hunting party returned, got a bison, and the digging of the well had to be stopped.

He had tasted well water before, and the water from the three wells was a bit salty, and it was unknown how much salt it contained, but at least it proved that there was a lot of salt here, and the salt content should be relatively rich.

The well can be regarded as finished, but it is a rough product, and the well wall needs to be finely treated. Now it is a bamboo tube well, and it can also be dug into a gourd well. Well, the point is not the shape of the well, but the depth, if you can dig out the brine directly, it will be a big deal.

The beef has been cut out, stewed in a pot of bamboo shoots, absolutely delicious, directly open to eat, as long as it is not wasted, how much can be eaten, it is a reward for everyone's hard work today. But in fact, he is generous to others, because the prey is hunted by the warriors, and life is so unequal, there can be no world harmony.

Bamboo shoots and beef are a perfect match, Su Yang eats with a mouth full of oil, and sleeps well at night.

When I got up the next day, I saw that the level of the well water was different, so I continued to work and hoisted the muddy water inside in a clay pot, which must also be done to keep the well water clear, otherwise it would rain casually, and the water would be very muddy.

After a busy morning's work, the mud was scraped almost clean with pottery shards, and some stones were thrown into the well, waiting for the water to be stored. This kind of household well, after the water is drained at one time, it takes two to three days to fill up.

He didn't care about the other two wells, and the well that produced the most water continued to dig deep, about seven or eight meters deep, and stopped again.

The next day, he continued to lift the muddy water out of the well, but the well could not be dug any further, but he still wanted to see where the rock layers were. I found a straight bamboo, nailed it to the bottom of the well, and kept knocking it down, if it was a soil layer, then it was possible for the whole bamboo to be driven in.

On the other hand, if it is nailed to hard rock, even if it is not a salt mine, then the bamboo will not be able to nail it anyway.

However, something disappointed him happened, the entire bamboo six or seven meters long was punched in, and no hard things were touched. In this way, it has been hit to a depth of about 15 meters, and it is still a layer of soil, and it is really difficult to mine salt ore.

If the salt mine is hit, it is likely that the brine will be sprayed out directly, and for some high-purity salt ore crystals, it can be used directly.

Su Yang suddenly thought of a problem, if the brine is exposed to the air for a long time, it is likely that the water will be wasted and cannot be boiled into salt. If this well penetrates the brine layer, I am afraid that it will not be mined for long, because it is too permeable and tragic.

No wonder, the well salt in his impression is very small, and the well can be covered with a spittoon, fortunately he reacted in time, otherwise the brine might be wasted.

As for the crystallization of the salt mine, it doesn't matter, there is the brine on the salt side, which is dissolved from the salt ore, and it is generally dissolved and taken immediately, so there is no problem of the brine dissipation.

And now he wants to hit the brine layer directly, once successful, there will be a large amount of brine available, but if the boiling cannot be completed in a short time, and the borehole is so large, the brine layer below will be wasted, resulting in waste. Of course, there is another problem here, if the wellhead is larger, then after digging deeper, the well is easy to collapse.

What now? Could it be that I have done useless work and wasted three or four days here in vain.

Su Yang rubbed his hands and walked back and forth, the salt well in his memory was seven or eight hundred meters deep, which was very different from his household well, and that well had existed in ancient times.

When the ancients did not have modern equipment, how did they dig a deep well? Su Yang was puzzled, and left the three wells alone, and when the water was clear, he tried to boil the salt to see how much salt it contained.

After a long time, I returned to the starting point, and directly drilled the well with the current conditions, it didn't work at all, it seems that the only way to drill a hole diagonally down, but this is a big project, and it will consume a lot of labor here, tangled! (To be continued.) )
