Reborn Tang Emperor Li Chengqian

Chapter 442 Pressure Wells

Not long after Xue Rengui arrived in the Andong region and took the post of the Protector of Andong, according to Li Chengqian's will, he sent heavy troops to guard the traffic arteries and important checkpoints in the Liaodong and Andong regions.

At the same time, a population of [-] households migrated from the Andong area to the south of the Jianghuai River and Huaihe River, and a large number of Han people migrated from there to fill various parts of the Andong area, where they lived mixed with the local people.

They also recruited these people who lived in a mixed environment, and selected a group of soldiers and soldiers to form a reorganized and mixed garrison regiment with these people to maintain the law and order in the Andong area.

Cultivate the fields, reward production, cultivate the fields during busy seasons, and practice during slack seasons, strictly in accordance with the land equalization system and the government army system.

Xue Rengui treated the people generously and favored the people in the Andong area, so that the survivors of the original Goguryeo received the same treatment as the people of the Tang Dynasty.

Under Xue Rengui's governance, the public security in the Andong area is stable, and the people's living standards have been greatly improved, which is better than before.

Xue Rengui implemented a benevolent government in the Andong area and loved the people like a son, so he was naturally supported by everyone in the Andong area.

This disintegrated Silla's desire to encourage the Goguryeo survivors in the Andong area to oppose the Tang Dynasty. Without anyone taking the lead in doing things, the Andong area was peaceful.

Chang'an, inside the Daming Palace.

"Everyone! Zhongshu servant Di Renjie sent back news that the disaster relief in Shandong, Jiang, and Huai areas has been successfully completed. The common people have food for the winter, and there is no problem in surviving this winter." Wang Quan sent Di Renjie with Di Renjie in his hand. report said.

Li Chengqian didn't watch it himself, but let Wang Quan watch it, and then told him the situation.

"This is a good thing. I am still worried that the disaster relief will not go well. The common people will not be able to get the disaster relief supplies from the imperial court, such as food, cotton clothes, quilts and other winter things."

"I am worried that they will starve to death without food. How can they survive this winter without cotton clothes, especially when they are hungry and cold, it is simply miserable!"

"It's all right now, Di Qing sent me good news, and I can sleep peacefully at night." Li Chengqian smiled.

This is the second good news he heard besides the demise of Goguryeo.

"The matter of disaster relief has been resolved, but..." Wang Quan hesitated to speak.

"But what? Could something be wrong? Tell me!" Li Chengqian frowned and asked.

"It's just because of the drought that there is no water in the fields. If it doesn't rain next spring, it will be impossible to sow seeds. Even if the current difficulties are overcome, it will only treat the symptoms and not the root cause."

"The fundamental problem can't be solved, and the people still have to suffer. The court has limited food and grass, and I'm afraid it won't be able to continue to provide relief." Wang Quan said.

This is indeed a major problem.

If there is no way to sow seeds in spring, the people will have no harvest, and if the people have no food, there will be no food to hand over to the court.

The imperial treasury will reduce income, and many facilities have to stop construction because there is not enough money and food.

If natural disasters such as floods occur again, the imperial court will not be able to provide money and food for disaster relief, and if they cannot provide disaster relief, it will cause a series of bad effects.

Therefore, this problem must be solved, and it is urgent.

"Go and call the craftsmen, I have something I need them to build." Li Chengqian said.

"I'm going now, servant girl!" Wang Quan hurriedly saluted and retreated.

Wang Quan quickly called the craftsman to Li Chengqian, and Li Chengqian handed a sketch to the craftsman.

"You build the objects on the sketch according to this sketch as soon as possible, the sooner the better." Li Chengqian said.

"Your Majesty! Forgive me for taking the liberty of not knowing what this thing is and how to assemble it?" the craftsman asked while looking at the sketch.

There is no problem in building the parts drawn on the sketch. These are not problems, the key lies in how to assemble them.

The sketch did not indicate how to assemble the object, nor did it explain the specific function.

"This thing is called a pressurized well. Now the capital and Shandong, Jiang, and Huai areas are in drought. Although the imperial court has found relief food supplies, the victims no longer have to suffer from hunger."

"However, no one can guarantee whether it will rain next year. If the drought continues, we will not be able to sow food. My people will still have to endure the pain caused by the drought."

"Although it is dry now, there is still a lot of water stored underground. As long as the groundwater can be opened up, we can rely on this pressurized well to pump the groundwater up."

"At that time, not only can the drinking water problem be solved, but also the farmland can be irrigated, and crops can be grown." Li Chengqian explained.

"I have built countless instruments in my life, but I have never seen such a wonderful workmanship. It is really rare in the world! Now, it can be regarded as an eye-opener."

"By the way, Your Majesty hasn't told me how to assemble the pressurized wells, how many are needed? And how to find groundwater?" the craftsman asked.

"This is simple. The casing of the pressurized well is made of iron, with a piston on the top and a valve on the bottom. You just need to assemble it like this." Li Chengqian pointed to the sketch and gave instructions to let the craftsmen know how to assemble the pressurized well.

Both the piston and the valve are one-way valves, and the working principle of the pressurized well is to pass through these two one-way valves to make the air go up instead of down.

When the long handle is pressed down, the valve opens when the piston moves up, and the air in the lower pipe can be pumped into the upper cavity.

When the piston goes down, the valve is closed, and the air comes out from the edge of the piston. This cycle will evacuate the tube below, and the water will be pumped up under the action of atmospheric pressure. The function of water diversion is to seal.

Pressurized wells are actually using the "three points" of the lever principle to pump up groundwater. Its fulcrum, resistance point, and force point are all on the long handle.

After listening to Li Chengqian's explanation, the craftsman and others were stunned, "It's really ingenious! It's ingenious!"

"Your Majesty! Now that we have a pressurized well, how can we find groundwater sources?"

"You just need to build pressurized wells with peace of mind. I need tens of thousands of such pressurized wells right now. I have sent people to search for underground water sources according to the method I gave, and they will be found soon."

"But before that, you build a pressurized well first, and I want to try the effect first." Li Chengqian said.

"I understand, I will do it now." The craftsman bowed and stepped back.

Soon, the craftsman built a pressurized well according to the sketch given by Li Chengqian.

The experiment was carried out in a place with groundwater. After the pressurized well was installed, the pressurized water test was carried out. Soon the movement of the long handle drove the piston to move, and the groundwater was pumped up.

The experiment was successful, and everyone cheered. With the pressurized well to pump up the groundwater, there is no need to worry about drought.

The craftsmen immediately invested in the construction of the pressurized wells and distributed the pressurized wells to the dry areas.
