Zhang Beichen also knew the situation in Baiyang County. When he checked the county's information these days, he knew that Baiyang County used to be a barren land.
Originally, the population was not large, and the people could still live by relying on the Longyan Spring. However, as the Qin State lost more and more land, the number of refugees increased, and the number of people migrating here also increased, and the Longyan Spring was no longer enough for them to draw water.
Zhang Beichen conducted a small investigation on the geographical environment here. According to previous data, Baiyang County also had an above-ground river hundreds of years ago, but it later dried up.
However, Zhang Beichen deduced based on various data that there should be enough groundwater underground in Baiyang County. However, the geological structure here is special. The underground is mostly rocky, making it difficult to drill wells, and the depth is not deep enough to find groundwater.
As a science student and with some experience in simulation, Zhang Beichen already had an idea in mind.
He said to everyone: "Since this county is the magistrate of Baiyang County, these problems will naturally be solved by this county. But your violations must also be dealt with in accordance with the law."
After hearing his words, Yu Yong said: "Handle it? Can you handle it? Mr. Zhang, if you can solve the problem of water supply for the people in Baiyang County, we will not have to depend on the sky for food and risk our lives every year. I, Yu Yong, do not need you to execute me."
, I will take matters into my own hands and rectify myself!"
"Yes!" Other felons also said together, "If you can make everyone use water, what if we commit suicide? At least our descendants will not have to kill each other for a bucket of water like us!"
"Okay!" Zhang Beichen looked at everyone and said, "Today, this county will convince you!"
"Ada, bring the tools from the county government and dig a well to get water!"
"Yes!" Ada and others returned to the county office to move things.
Bai Liangpu and others were laughing secretly.
"This guy is really an idiot." Bai Liangju laughed, "If it were so easy to dig wells in this area, would they still be fighting for water?"
"He is desperate!" Bai Liangpu looked proud, "Now he neither dares to kill people to rectify the law, nor can he let people break the law, so he can only take a gamble. Unfortunately, even if he digs here for three days and three nights, he will not be able to dig out any water.
Come!"
"Sir, do we really need to dig a well to get water?" Liu Wen looked hesitant. From his experience, this kind of thing is in vain.
"Of course!" Zhang Beichen ordered, "Master Liu, take me to find the ancient river channel in Baiyang County."
"This... okay." Liu Wen had no choice but to lead him the way.
The prisoners and civilians all followed him to see what tricks Zhang Beichen could pull off.
Not long after, Ada and others got the tools.
Bai Liangju looked over and saw the guards pulling a cart. On the cart were hollow bamboo tubes of similar diameters, with iron awls, shovels and some metal objects on them.
"I thought the county magistrate had some means to dig a well with just these things?" Bai Liangju said with a smile, "What is the bamboo tube used for? Is it used as firewood?"
Everyone was puzzled.
Zhang Beichen is still choosing a site. He also specially invited a few old people who are good at digging wells to help look at the location.
A group of people came to an ancient river, which had been dry for more than a hundred years. The original river had long since become a wasteland.
An old man said: "Sir, I heard my grandfather say that there used to be a river here. The terrain here is low-lying and is suitable for digging wells."
Liu Wen quickly reminded Zhang Beichen: "Sir, the county once sent people to dig a well here. It took several months to dig a full two hundred feet, but no water came out! There is too much gravel below, and the deeper it becomes, the more difficult it is to dig. You
Look, over there is the well pit!"
One foot in the Qin State is approximately equal to 23 centimeters, and two hundred feet is approximately close to 46 meters!
Zhang Beichen went over and took a look, and sure enough there was a big pit. At the bottom of the pit, gravel and soil were mixed together.
Seeing this, Ah Da and others were also embarrassed and said to Zhang Beichen: "Sir, this place is not suitable for digging a well. We have dug it so deep and there is no water yet. It is probably a waste of time to dig any more."
"I'll go down and have a look." Zhang Beichen asked someone to lower him down with a rope. He touched the cave wall and found that the cave wall was indeed wetter than the top.
He went up again and walked around for several miles.
Everyone was waiting for him, and Yang Shan asked impatiently: "Zhang Beichen, can you do it? If not, just let him go and don't waste everyone's time here!"
Zhang Beichen glanced at him and didn't reply. He observed the surrounding environment and already knew that there was water underground!
Because when he went down to the abandoned well, he noticed that the underground temperature was lower and the cave walls were wetter than the ground. The surrounding trees and vegetation were obviously thicker than other places.
Some plants have well-developed root systems and are able to absorb water from deeper depths, indicating that there is water underground.
As for why it was not drilled out, there is only one reason, and that is that the well-drilling technology here is not developed enough, so it cannot drill to a depth of fifty meters.
In his previous time and space, even wells in rural areas were often dug two to three hundred meters deep. But in this era, it was very difficult to dig hundreds of meters deep by relying on manual digging!
"Get ready to dig a well! Just continue digging along this abandoned well!" Zhang Beichen ordered.
"Yes!" The officers were all ready, but Zhang Beichen said to Che Yang: "General, please ask your soldiers to help. They have advanced cultivation and are faster!"
"It's okay!" Che Yang asked his soldiers to help dig wells. Their strength and endurance were stronger than the guards. They dug wells and dug rocks. The guards helped carry the mud and rocks in hanging baskets.
The soldiers took turns to go into battle and soon increased the depth of the well by dozens of meters.
An hour passed, and everyone at the scene was impatient to wait. There was still no water coming out of the bottom, and the soldiers had been consuming spiritual energy, and they couldn't bear it anymore.
"Master Zhang, if you use this method, you may not get any water even if you dig for another month. Do you want us to wait here for a month?" Bai Liangpu asked.
"Why are you in a hurry?" Zhang Beichen took a look at the depth and found that it was almost enough. He ordered someone to put down the prepared things and install something like a large wheel with a metal cone tied to it with an iron rope.
"What is this?" Everyone had never seen this thing before and looked confused.
"You step on this wheel and dig into the ground with an iron awl!" Zhang Beichen ordered.
Everyone believed that the iron cone hit the ground and made a hole the size of a bowl in the bottom of the cave, which could easily penetrate even rocks!
Liu Wen was surprised and said: "This is much more labor-saving than human labor!"
That hard rock was shattered so lightly!
They didn't understand that this was actually a lever linkage device in disguise. After connecting the iron cone, the soldiers pedaled to turn the wheel and drive the iron cone, forming a human impact drill!
This is not Zhang Beichen's own creation, but a deep well digging technique pioneered by people in his original time and space more than a thousand years later.
Well digging in the Seven Kingdoms is all about digging shallow wells, which is time-consuming and labor-intensive. Think about it, if you have to dig 200 meters, that’s about 870 feet!
If we use manpower to dig this, how long will it take? Even a skilled martial artist will be exhausted!
Furthermore, when digging shallow wells, the area should be larger, providing space for people to stand, dig and carry mud and rocks.
To dig a deep well, you only need to dig a hole the size of a bowl.
"Sir, are you digging a well? It's such a small hole? How deep can it be dug? And how to get out the mud and rocks inside? Even if water is dug out, how will the water come up? Are you kidding me?" Yu
Yong and others couldn't understand and asked.
"In another two hours, the water will come out!" Zhang Beichen said firmly.
He naturally has a solution to these problems. After digging to a certain depth, he puts in a bamboo tube. A one-way valve is placed on the bamboo tube, which can use air pressure to pull out the mud and stone inside, and then put the drill bit in and drill.
Repeat this cycle until water comes out.
This is the deep well drilling technology. In the agricultural era, this technology could dig wells hundreds of meters deep. It is called the first generation version of oil drilling technology.
