At present, the largest scale of the craftsman's workshop is the lime kiln, the brick kiln, and the coal (coal) field developed deep in Baohua Mountain, thirteen or four miles away from the back mountain. Currently, relatively cheap coal (coal) is basically used to burn lime and make bricks.
Coal), replacing the firewood and more expensive charcoal that had previously cleared the surrounding mountains.
Likewise, the camp military government only needs to spend 1,200 shi of japonica rice every month in exchange for 200,000 to 300,000 large and small green bricks, 2,000 tons of lime, and 600 loads of charcoal from the craftsman's workshop.
However, there are still many areas for improvement in the craftsmanship aspect.
Han Qian didn't do it before, mainly because he didn't have that much energy to take care of this, especially during the four months he left Jinling. He could only ask Fan Dahei to lead the engineers in various fields to expand the scale first.
Today the third prince Yang Yuanpu came over. Han Qian took him to visit the workshop and taught him the art of studying objects. He talked eloquently all the way and seemed completely unaffected by yesterday's events.
The word "Gewu" comes from "The Great Learning", the first of the four books of Confucianism. The chapter opens with a clear meaning: "In ancient times, those who wanted to establish virtue in the world first governed their country; those who wanted to govern their country, first regulated their families, and wanted to regulate their families.
A master should first cultivate his body. If he wants to cultivate his body, he should first rectify his mind. If he wants to rectify his mind, he should first be sincere in his intention. If he wants to be sincere in his intention, he should first develop his knowledge and study things..."
As far as Confucianism is concerned, the very beginning of Confucianism points out that "investigating things" is the most basic prerequisite for attaining knowledge, correct mind, self-cultivation, and harmonious family.
However, for thousands of years, Confucian scholars have interpreted the word "Gewu" and focused on exploring its principles. In addition, since the pre-Qin Dynasty, the attack on craftsmen and practitioners and the social contempt have led to the evolution of the study of "Gewu" into metaphysics.
, mind science, but it is not really based on the fundamental interpretation of "discriminating physical properties" and "cognizing objective laws", so that after thousands of years, it has not really developed into a systematic science.
This is also the greatest insight Han Qian gained from integrating Zhai Xinping and dream knowledge for more than a year.
If you want to distinguish physical properties and recognize objective laws, the more important prerequisite is to practice everything.
For Han Qian, dealing with the heavy and complicated affairs of the workshop is actually a process of sorting out and integrating dream knowledge.
This knowledge, even if Han Qian only taught him the most basic knowledge of objects and everything in the workshop, still had a great attraction for Yang Yuanpu.
Chai Jian, Li Chong and other accompanying persons looked at each other in shock. They didn't know where Han Qian's leisurely mood came from, or maybe he had ulterior motives for saying these words.
Although since the late period of the former dynasty, vassal towns have been separated, warriors have been in power, the imperial examination has actually been abolished, and the status of Confucian scholars has not been highlighted.
, all advocate pragmatism, but in terms of legal principles, they have not subverted the "exclusive respect for Confucianism" promoted by Dong Zhongshu more than a thousand years ago.
Although Chai Jian, Li Chong and others were martial artists, they had also studied diligently since childhood. It can be said that they were deeply influenced by traditional Confucianism. Even though Chen De was a pure martial artist, he felt that what Han Qian said was very different from what he usually heard.
different.
Of course, Chen De, Chai Jian, and Li Chong may not agree with Han Qian's views, but their academic background is far from enough to stand up and refute Han Qian. At the same time, they are also shocked by Han Qian's knowledge and breadth of knowledge.
.
However, what made Chai Jian and Li Chong even more unbearable was that in the workshop, which craftsman was slightly better, Han Qian called the third prince Yang Yuanpu to introduce him to them, and asked them to personally introduce it to the three princes.
The prince explained the craftsmanship, and they guessed that Han Qian was using the third prince to weaken the power of the military officials in the eyes of the craftsmen in the workshop. However, the third prince looked approachable, so they had nothing to do.
The third prince treated Han Qian as "Master Han", which made Chai Jian and Li Chong even more helpless.
After visiting the craftsman's workshop, they had a brief lunch there. In the afternoon, Han Qian led the third prince, who was in high spirits and not aware of the hard work, to the coal yard deep in the back mountain for inspection.
Going down from the coal yard and heading north along a stream, he saw a large amount of stones piled up at the mouth of the stream, and hundreds of strong men in ragged clothes digging a deep channel on the side of the stream mouth. Yang Yuanpu curiously asked Han Qian
: "Master Han, what are you doing in such a big way here?"
"Build a stone dam to store water!" Han Qian said, "This is also the first thing I have to do when I return to the villa. I have already ordered the craftsmen to prepare it for a long time."
After going down from the coal yard, the stream on the west side is connected with the stream flowing through Qiuhushan Villa. Then at the Jiangfang location, because the terrain is gentle, the river is further widened, forming a more than 20 steps wide.
Taoxi River bypasses Junfu Tucheng and then merges into Chishan Lake.
Han Qian planned to build a stone dam at the mouth of the creek northwest of the coal field. He wanted to raise the water level of the stream in the north by three to four meters, so that the mouth of the creek could be extended northward to the five or six mile long valley deep in Baohua Mountain.
, can be turned into a small mountain lake reservoir.
On the one hand, more grain fields can be reclaimed on the periphery of the reservoir to divert water for irrigation. On the other hand, and the main reason is that at the edge of the coal field below the creek mouth, two coal-crushed water dams have been built and put into use. Stable
water flow.
Limited by mining technology, the coal blocks dug out from the current mines are relatively large. If used directly to make bricks and burn lime, the combustion will be slow and incomplete. This is also the case in current brick kilns. The cost of lime kilns cannot continue to decrease, and the production capacity
A key bottleneck that cannot be improved further.
However, in fact, brick kilns and lime kilns do not need to be expanded. The efficiency can be increased by half by simply crushing the coal blocks initially and removing the gangue with low coal content.
Han Qian just gave guidance through letters and sent back to Jinling the diagram of the continuous machine-operated water turbines left by General Du Yu six or seven hundred years ago, and asked the workshop to imitate two connected-machine water turbines, which are also simple versions of hydraulic coal crushers. At present,
Although it has only been put into trial operation for half a month, the results are quite good.
The problem is that without building a reservoir to artificially control the water flow, the existing two hydraulic coal-crushing buckets are difficult to operate not only during the dry seasons in autumn and winter. When there is abundant rain in summer and autumn, the water flow alternates between rapid and slow, and the two hydraulic coal-crushing buckets are unable to operate.
The operation is also difficult to stabilize.
If you want to establish a relatively complete production system and rely on the weather, it is actually the most inefficient.
At present, only by building a reservoir in the upstream can we ensure stable water flow in the downstream construction and use more hydraulic equipment; and we must ensure that the coal from the coal field can be transported out of the mountain by shallow-bottomed boats in autumn and winter, and more
Make sure the water flow does not dry up.
Before Han Qian went to Xuzhou, he arranged for a craftsman's workshop to mine the stones needed for dam construction.
Before Han Qian returned to Jinling, Fan Dahei had already arranged for manpower to dig a diversion channel on the west side of the Xikou.
Fan Dahei was kicked out of Jinling by Han Qian, but many things were still progressing in an orderly manner. Under Han Qian's personal intervention, he was not delayed.
After the diversion canal is dug out in two days, a mud embankment can be built upstream of the creek mouth to block the stream water from flowing into the diversion canal to flow downstream. The water-retaining stone dam can be formally built at the creek mouth.
"There are heavy rains, flash floods, and turbulent water in the Jianghuai River. How strong must this stone dam be built to be as stable as a mountain?" Yang Yuanpu actually asked with some worry.
"Your Highness, you see these stones have notches - when building the dam, we will pour molten iron into the notches to make the stone dam integrated..." Han Qian explained briefly, as for the more complicated
There is no need to explain the calculation in detail to Yang Yuanpu.
"How much food will this cost?" Yang Yuanpu asked, he was still concerned about this issue.
"Fortunately, two or three feet of rock formation is dug out from the mouth of the stream. The stone dam only needs to be built thirty steps long to seal the stream. It is not as difficult as imagined. The craftsman's workshop can still barely do it..." Han Qianhun said nonchalantly.
.
Although Han Qian didn't care, Chai Jian and Li Chong secretly clicked their tongues.
Although Zuo Si did not spend most of the money spent by the camp military government, Zuo Si's expenses were far beyond their imagination. Even if Zuo Si's newly added manpower was not included, they did not know how Han Qian had managed it before.
Came here.
As for the construction of the stone dam, Han Qian also explained to Yang Yuanpu many things about the construction of flood discharge channels, diversion channels, ponds, terraces, as well as water tillers, water mills, water drainage, and even mechanical tillers as early as hundreds of years ago.
Hydraulic equipment was invented thousands of years ago.
As for the theoretically feasible hydraulic spinning machines, hydraulic looms and hydraulic forging hammers, Han Qian would not talk about it, at least not in front of Chai Jian, Li Chong and others.
Tunying Military Mansion is located at the southern foot of Baohua Mountain and stretches for nearly twenty miles. There are limited cultivated fields that are relatively flat between the mountains and lakes, but there are many streams and rivers that can be used in the mountains, and there are enough gaps, so it can be said that there is abundant water resources.
.
Han Qian suggested that the third prince, Yang Yuanpu, take over more affairs from Taifu Temple, the Ministry of Internal Affairs and even the Ministry of Industry for the military government workers, which would be enough to feed tens of thousands more people and reduce the financial and food pressure on the camp military government.
For example, the official salary issued by the imperial court was made from grains such as rice millet and other grains, which were hulled and refined. In the early years, sticks were used to peel the grains, and later they were crushed with stones and treadmills. Although water mills and even machine mills were used as early as the 700s or 800s
It was invented many years ago, but there are no high-altitude streams in Jinling City. It mainly used official slaves or animal power to pound grain and grind rice.
Although the cost of using official slaves is extremely low, the problem is that even if they are used, they have to be fed and drank to maintain their strength for servitude, and the cost of controlling thousands of official slaves is also extremely high.
If the army workers can make use of the streams at the southern foot of Baohua Mountain to build water mills, mills and other equipment, as long as the cost of grinding rice can be lower than using official slaves, the third prince can take over the work, and your majesty will not
Not allowed.
Chai Jian and Li Chongneng realized that Han Qian was talking about these things in front of the third prince, and he was still trying to make things difficult for Zhou Yuan, a worker who joined the army. They secretly felt that what happened in the past two days was not because Fan Dahei and Lin Haizheng were kicked out.
In Jinling, Han Qian finally called Zuo Si's disciples together again.
However, they can't say that Han Qian's suggestion has no merit. After all, Zuo Sijiangfang is doing this with great fanfare. Why should Zhou Yuan say that he can't do it and it can't be done?
