Chapter 547 Choose the Road

Ever since Yang Reform took care of the navy, he has let go of one thing on his mind. However, more important things need to be prepared. Now the Songshan Fort is being fought hard, and it may be breached that day. This landing, I have to prepare immediately, and I have to be ready to rescue at any time, so I am even busier.

It is impossible for Yang Reform to go to battle in person, but even if Sun Chengzong is asked to supervise the teacher, Yang Reform is still worried, and the staff department has done a lot of deduction. If Yang Reform does not say anything else, at least he must see the possibility of victory in the deduction sex.

"200 million silver coins..." Yang Reform gritted his teeth. Yang Reform was going to the platform today, and asked Sun Chengzong and Qin Liangyu to study the battle plan, and took the time to correct the students' "homework". When he saw the homework submitted by a certain student, Claiming to build a seamless cobblestone road from Beijing to Tongzhou would cost at least 200 million silver coins, and some corvee would have to be collected, otherwise, it would be even more expensive. It was worth a little more money, and Yang's enthusiasm for reforming and building roads was instantly poured with a bucket of ice water.

"Your Majesty..." Wang Chengen asked with concern, seeing the emperor bared his teeth, Wang Chengen thought the emperor was not feeling well, or had a toothache.

"It's okay, it's okay..." Yang Reform quickly said, and while talking, he looked at the student's "homework", but it was handed in by Liu Mao. It stands to reason that this Liu Mao would not talk nonsense now, but this Why is the road so expensive?
According to this cost, Yang Reform did not dare to talk about large-scale road construction easily. It is calculated at 200 million silver coins, forty miles, and a mile road costs 500 silver coins. Calculated at 100 meters per mile, one meter It costs one hundred silver coins. If it is calculated as six or seven square meters per meter, this square will cost more than a dozen silver coins. Of course, if it comes to stone slabs, one square will cost five to six stone slabs. The price is only two or three silver coins, which is really expensive. However, these stone slabs are quite thick stone slabs, which are guaranteed to last for more than [-] years. Once paved, they are very durable.

Of course, the price cannot be all calculated on the stone slabs. This road also has three floors. Ditches, bridges, trees on both sides of the road are also counted.Speaking of which, 200 million silver coins is not too expensive. After all, this stone slab was mined from the mountain, and it had to be transported for dozens of miles, or even hundreds of miles, to the place where the road was built. There were no heavy machinery in ancient times, and it was all done manually. , manual handling, the cost of the project is so expensive, Yang Reform can also understand.

This top-level road is so expensive, Yang Reform can't stand it. Although this road is very expensive, Liu Mao also vowed that it can last at least a hundred years. The road, forty miles, can pave two roads with a width of six or seven meters in the north and south of Beijing city. The north and south of Beijing city are only ten kilometers away. …

Of course, if it is to repair the current road from Beijing to Tongzhou, it is much cheaper, tens of thousands of taels of silver, just pull some mud to fill the hole, and repair the bridge, it will not cost much at all. It is a little more expensive, because stones have to be paved on the foundation of the current road, and a layer of compound soil is laid on top of the stones. Calculated, it also costs 40 million silver coins.

Yang Reform understood why corvée was always used as an important supplement to taxation in ancient times, and why the cost of construction in ancient times was so low. If all corvee was collected, the construction cost would be much lower, as long as some money is paid to support the peasants who do corvée. If you don’t have stone slabs, you can go to the mountains to collect them yourself. If you don’t have a carriage, you can build them yourself. If you don’t have steel brazing, you can send people to smelt iron. If you don’t have lime, you can burn them yourself. The cost is the lowest, and you will only buy it with money unless it is absolutely necessary, such as grain and salt. In fact, even grain and salt can be deployed.Yang Reform watched the tears, and summed up the Ming Dynasty's projects in one sentence, that is, "do it yourself, and have enough food and clothing."

Now that Yang Reform intends not to use corvees, but to build roads directly as a business, that would simply be making him suffer, and the cost would be prohibitively high.

The sad Yang Reform turned over the homework of other students. Sun Yuanhua mentioned that the matter of burning stones had already begun.

It's not how lucky Sun Yuanhua is, but that Yang Reform has already explained that during the steelmaking meeting, Yang Reform asked Sun Yuanhua to refine all the stones that can be refined in the world. Therefore, Sun Yuanhua understood the types of stones in the world. It is relatively clear what kind of stones have basic uses and what is burned out. Sun Yuanhua already has a rough idea. Now the emperor asked him to burn lime from those stones, which is comparable to hemp stones. On the contrary, he has a lot of experience, and after burning, he will have a general direction. Therefore, Yang Reform asked Sun Yuanhua to burn cement, and Sun Yuanhua quickly touched the edge of the cement.

"Natural cement?" Yang Reform looked at what Sun Yuanhua described in his work, and he was basically sure that what Sun Yuanhua burned was natural cement. This kind of "cement" that only needs one kind of ore can be burned. So several kinds, judging from the description of the ore and the place where it was dug, it is natural cement.

This kind of cement is impossible to pave roads, that is to say, it can be used as an adhesive, especially for paving sewers. What is that? The grade is too low, and it will be crushed after a few days for road construction.

Yang Reform looked at it for a while, and he was even more troubled about how to produce cement on a large scale. In the era without steam engines, we could only rely on water conservancy, animal power, and manpower. It was really a luxury to produce cement on a large scale.

"What I want to tell the Qing family is the summarization and refining of experience. I have repeatedly ordered the Qing family to record the refining process. Li Shizhen divided the medicinal herbs in the world into categories, classified them according to the outline and purpose, and recorded the uses, medicinal properties, colors, how to obtain them, how to process them, and even provided them with pictures. It is easier for future generations to understand and learn, and it has great merit. Sun Qing's family may wish to learn from Li Shizhen, and classify the world's ores into categories, outlines, and compile them into books, recording their characteristics, functions, colors, Shape, where to get it, what can be fired, and various changes at various temperatures. In this way, the ore in the world will be clear at a glance, and it will be easier for future generations to learn... In addition, the text should be as plain as possible so that it can be read I understand..." Yang Reform put aside some distracting thoughts and began to write his own comments. Although there is no clue about using cement to build roads, the basic work of these scientific researches still has to be guided by Yang Reform. Realizing the importance of experience summarization and refining, we plan to further expand the work of experience summarization and purification in the metallurgical industry.

"...About the kind of stone that the Qing family mentioned, I think it's not bad. Then, how to fire it on a large scale, how should the Qing family do it? I plan to build a large-scale construction project. Once it starts, the demand for this kind of thing will definitely increase. It is extremely large, and a small amount of production is definitely not enough..." Yang Reform still started to talk about cement.

"...Shi Kefa is building a new Shanghai city in Shanghai, and he also needs a lot of this kind of stone, which is used as adhesive. How to reduce the cost of firing, the Qing family must work hard..." Yang Reform wrote another paragraph, the cement came out, But it is not expected to be used for paving roads. It may be okay to use as an adhesive. Building a house is much stronger than using lime as an adhesive. Yang Reform wants to promote cement in this new city of Shanghai. A real "new Shanghai".

With cement, at least several floors of buildings can be repaired. Yang Reform has seen many buildings repaired with bricks and wood. The adhesive used is cement, and the floor is made of wood. This kind of building is not uncommon. Once cement is widely used in the construction field, even the buildings of the early 21th century can be realized. Once cement is used in Shanghai, a new Shanghai with the architectural characteristics of the early [-]th century, It can be realized in the Ming Dynasty, which will be a great improvement for the progress of history.

"...I asked about the cost of paving the stone road a few days ago. It was really expensive, and I sighed. Therefore, I might build the road with three-component soil, which is much cheaper, but the road with three-component soil does not condense enough. , I’m afraid of water, it’s not ideal,... I just thought, if the road of Sanhe soil can condense better, that would be great, maybe it can be unsatisfactory, barely usable, Qing’s family might as well try to burn the Sanhe soil to see, see Can there be any changes? I think that when mixed with other soils, it is still mud, but when mixed with three-component soil, it has obviously changed a lot. Maybe there will be any surprises..." Yang Reform is not afraid of trouble , wrote a long paragraph, now the process of burning cement at Sun Yuanhua is still exhaustively exhausting a single ore. It has to wait until two or three substances are mixed exhaustively. I don’t know that it will burn until the year of the monkey. Yang Reform was anxious, so he directly named and burned the three-component clay. This three-component clay is actually the raw material for burning cement. Yang Reform was going to open the golden finger.

Construction has already started in Shanghai, large-scale brick burning is underway, and a large number of buildings are about to rise from the ground, but whether to build new Shanghai into a new city of classical China, or to build Shanghai into a new city with architectural characteristics of the twentieth century, Yang The reform clearly chose to build Shanghai into a new city with the characteristics of the [-]th century. Therefore, cement must be produced, and the epoch-making cement such as "Portland" cement must be produced directly instead of natural cement.

After finishing writing the comments to Sun Yuanhua, Yang Reform turned to the "homework" from Yan'an Mansion. The cement road was hopeless, but the asphalt road was good news, that is, Yan'an Mansion was too far away from here, and it was really far from the economic center. It is too far away, and the determination and perseverance required to pave the road with asphalt are definitely beyond the imagination of ordinary people.

"...I was very surprised when I heard the Qing family talk about the various benefits of building roads with oily residue. They are not afraid of water or being crushed, and they feel soft when walking on them. I think this kind of road may be what I want. The Qing family might as well send some oil residue over here, I want to see for myself how the oil residue paves the road..." Yang Reform gave up the stone road and rejected the cement road, so he can only use it for the time being. Sanhe soil has been used to build roads, or directly build mud roads to repair the current roads.Instead, the asphalt road is regarded as a tough project.

"...I asked about the price of the oil. Capital lard costs sixty or seventy yuan a catty, and clear oil costs more than thirty yuan. Qing's lamp oil should be as low as possible, or twenty yuan, or fifteen yuan. Reduce the price of kerosene to about half of clean oil, strive to occupy the kerosene market as quickly as possible, strive to expand the market as quickly as possible, and increase the sales of kerosene as much as possible. As for the loss, it does not matter how much you lose How much will I make up? I will order the carriage yard to replenish the carriages needed by the Qing family as soon as possible, and don’t waste the oil residue I get. In addition to paving the road to Yan’an Mansion as I said before, I am going to pave the road to the capital. The south can go by water , try passing the Yellow River, although it is not satisfactory, it is still a way..." Yang Reform wrote another comment to Li Yanyi of Yan'an Mansion.

Since cement roads are not expected, stone roads are even less hoped, and concrete roads are dissatisfied, then only asphalt roads will be born. If asphalt roads are born, oil production must be increased. Yang Reform plans to further subsidize the oil industry. Money also needs to be used in the oil industry. According to the cost of the stone road, 200 million silver coins are needed for Shilili. If these 200 million silver coins are used to subsidize the oil industry, five or ten coins per catty of oil can be subsidized. Two million silver coins can be subsidized With 200 million catties of lamp oil, the oil output can reach [-] tons in one fell swoop.

The annual output of [-] tons was considered a colossus in the Ming Dynasty. In addition to the obvious driving effect on the local area, that is, the promotion of the oil industry is particularly obvious. The by-products of oil will also gradually appear in people's vision, such as oil The ink extracted from the oil, such as lubricating oil, and asphalt, etc., the petroleum industry will develop rapidly.

Yang Reform took a breather and felt that his arms were a little sore. He shook his arms and carefully reviewed the decisions he made. The "homework" he corrected this time can be regarded as setting the tone for the development of the Ming Dynasty for many years to come. When he thought of Shanghai in the [-]th century appearing in the Ming Dynasty, and thought of the asphalt road being paved in front of his house, and all kinds of horse-drawn carriages speeding on it, Yang Reform couldn't help feeling complacent.

"Your Majesty, is it time to go to the platform?" Seeing the emperor approving things by himself, Wang Chengen laughed, and didn't intend to leave after an hour, so he quickly reminded the emperor that it was time to go to the platform, Mr. Sun Ge Both Qin Liangyu and Qin Liangyu have been waiting for a long time.

"Oh... I see, let's go..." Yang Reform's dream was shattered, and he returned to reality from the infinite reverie. He hurriedly closed the notebook, put it away, locked it tightly, and was ready to go out.
