Chapter 2590 I am better than others
??Although most of Fei Qian''s territory is inland, Fei Qian has not relaxed his research on ship technology because of this.
The scientific and technological branch of ship technology is not a separate branch. In fact, there are many aspects that are interrelated with other technologies, such as metallurgy and architecture.
Let’s not mention metallurgy. How can architecture be connected with ship technology?
There is indeed.
An integrated display structure that combines metallurgy, architecture, and ship technology is the dock.
Whether it is a new ship or a ship repair and maintenance, a dock is required.
After a war on the water, ships will inevitably be damaged. If the basic structure is intact, it''s just that too many holes have been opened on the deck of the ship, and some places are burned out, making it impossible to continue sailing. When the waves bump, water pours straight into it.
Should such ships be discarded or repaired?
The answer is that if you can cultivate, you will try your best to cultivate.
As long as the basic structure is intact and important components such as the keel are not damaged, it will be repaired.
If you only need to build ships, you often choose a natural port and directly build a simple wooden frame or other type of "natural dock". However, natural docks are often restricted by terrain. If you want to build a new one and repair it at the same time, you have to Faced with the need to temporarily build or add a dock.
What Cai He saw in front of him was such a semi-dry dock built with cement...
A dry dock has no water. The so-called semi-dry dock certainly means that half of it has water and the other half has no water.
In fact, according to the needs of later generations for building and repairing ships, dry docks will naturally be better. It''s just that the watertight materials of this era are not up to standard, and some water will still seep in. So there is still a little water in some places, so if it doesn''t get in the way, don''t worry about it.
Ma Jun also came up with the idea of ??excavating a simple dock directly on the Yellow River, digging a long, wide and deep canal, and then building stone walls on the surface of the canal to glue it. After the canal is built, the water will be introduced, and the ship can follow the canal to the repair place. Then the water will be drained, and the ship can be repaired in this dock without water. After repair, the water will be put in , the ship can sail away.
Such a shipyard can naturally also be used to build new ships.
This plan was rejected because the investment was estimated to be too large. Mainly because without Lan Xiang''s assistance, the amount of earth and stone was really a problem that could only be piled up by manpower, and the development of the Sanfu area in Guanzhong did not require manpower. of?
Later, under Huang Chengyan’s joint discussion, it was changed to another alternative plan currently adopted.
Simple slide.
Simple slide uses a wooden slide and a large amount of grease to replace the upper pier and launch of the ship from the water surface to the slipway. The advantage of this thing is that the equipment is simple and easy to operate, and there are not many requirements for the hardness of the rocks and soil on the shore. It is just that it cannot carry too heavy a ship. If Fei Qian really takes out the ironclad ship one day in the future, I''m afraid I just can''t pull it anymore.
When facing a wooden building ship, this simple slideway similar to a semi-dry dock is quite good. Just level the original ground, add appropriate gravel and ballast, roll it flat, and pour cement. That’s it. And because of its simple structure, it is easy to disassemble and assemble. If you need to relocate, most of the equipment can be dismantled and moved to a new location.
Fei Qian took Cai He to see this dock to see the modification of old ships and the launch of new ships.
Laymen watch the excitement, while experts watch the door.
?Chai He is not a very good general. If he is allowed to go into battle to kill the enemy, he may not achieve much success, but his understanding of ships is better than many other generals.
It’s not surprising that each has its own strengths.
??Except for the weirdo Fei Qian, he seems to know a little bit about everything.
It is precisely because of this that many people in the Han Dynasty admire Fei Qian very much. These people can''t figure out why Fei Potential can do this. How many books do you need to read and how much knowledge do you need to master to do this?
In the end, in order to explain this point, it could only be attributed to Cai''s collection of books. Then there were rumors that Cai''s collection might contain Mohist treasure books from the Spring and Autumn Period, and there might even be some unpublished books left over from ancient times. secret…
When Cai He saw the scene in front of him, his jaw had been drooping, and he couldn''t close it properly.
Dahan''s current natural resources are relatively abundant, so the wood needed for the shipyard here can still be guaranteed. With the addition of cement, a powerful weapon, although there is no such brutal model as E or F in later generations, At least it''s close to C, which is pretty good.
? At the same time, the development of metallurgy also allowed Fei Qian to use part of the steel without hesitation, instead of having to select all the precious iron wood, saving some tree resources. The use of the boom pulley also makes manual towing relatively labor-saving. Concrete is poured into the steel pipe, and the bearings are lubricated with animal grease, so that the winch can withstand larger torques. Although it is not easy to deal with wooden ships, it is not easy. , but at least it’s not too strenuous.
Mainly a wooden boat, it has little weight. If you are not worried that iron will rust too easily, you can just use cast iron.
?Chai He looked to the left and touched to the right, almost falling to the ground at Fei Qian''s aura of entrenchment in the dock. Because he saw that some of the wood was high-grade wood that could be used as palace beams, and it had been dried in the shade!
What does this mean?
This shows that before this piece of wood was cut down, no, to be precise, before such a tree was cut down, perhaps Fei Qian was planning everything in front of him!
?This made Cai He even more humble.
??And Cai He saw an extremely unusual arrangement on the building ship in the dock...
He was very curious, and he also realized that the special vacancy might be a big killer, but he did not dare to ask.
That empty space is reserved for artillery.
When attacking a city, artillery with insufficient gunpowder yield is actually not as intimidating and threatening as kerosene catapults, unless the defenders on the city are willing to let Fei Qian put the artillery into the city gate and conduct direct fire to bombard the city gate.
Even if the city gate is directly bombarded, there are still ways to block the stone and sand to resist.
So the artillery that can produce 100% or even 200% of its power is actually on the water.
In this era when ships are basically made of wood, the emergence of artillery is almost equivalent to a dimensionality reduction strike. It only takes one shot to directly send the opposite ship back to the port to take advantage of the barrel. It is not an impossible task.
On both sides of the large building ship, there are gun ports.
Cai He looked at it, swallowing his saliva.
The side panel of the running position adopts a loose-leaf model, which can be pushed open. Normally, it can be put down.
?The position of the gun is fixed in the cabin to lower the ship''s center of gravity.
?In Fei Qian''s eyes, those artillery pieces seemed a bit crude, bulky, even dangerous and inaccurate, but in this era, they were indeed products that transcended time and space.
An improved version of the front-loading smoothbore.
Fei Qian smiled and took Cai He around without going into details. Anyway, he just let Cai He take a look and show off his strength.
It is actually not that easy for time travellers to turn their knowledge into productivity.
A simple dock seems to be extremely crude compared with later generations.
But it’s actually not easy.
Just like the various items on the ship, paint is of course the main anti-corrosion method at this stage. This is also common sense that travelers know, but should we use raw paint or cooked paint?
Some people say that it is better to use raw lacquer, while others say that it is best to use cooked lacquer, but Fei Qian knows that neither of these is good.
It should be anti-rust paint.
It’s a pity that there is no…
All Feiqian ships can sail in fresh water areas, but once they sail into sea water areas, the life of the ships will be greatly reduced. Many ships that can be used in fresh water areas for more than ten years will not last more than ten years in sea water. It will corrode in five years. The reason is that Fei Qian could not come up with the kind of special anti-rust and anti-corrosion paint used on the bottom of ships in later generations.
?Similarly, there are artillery. Fei Qian also knows that rifling is very important, but the problem is that materials science has not progressed enough. Even if materials science has progressed, processing technology must also be improved...
Fortunately, the steelmaking method of the Han Dynasty was already very good. The blast furnace and other things had already taken shape. Feiqian just added the research and development of refractory bricks and the converter plan, which made Feiqian''s current steel output and quality both outstanding. Already standing at the pinnacle of this era.
?Similarly, the technological development of refractory bricks has also further improved the technology of coal coking.
At the earliest time in Pingyang, Feiqian used charcoal to make iron and steel.
Later, coal from the Luliang Mountains was used, but the impurities in the coal were troubled for a long time. Finally, a method similar to making charcoal was used to make coke, and for a time, local methods were used to make coke.
Although local coking can provide a large amount of coke at one time, the qualification rate is too low, and related coking by-products, such as various oils, cannot be collected...
?The development of refractory bricks has made it possible to use new furnace-type coking. Except for a few parts that require iron sheets, the basic materials are bricks and refractory bricks. The entire coking process takes about ten days, and the passing rate of coking coal has also improved a lot. Of course, there is still a big gap between it and later generations, but it is already very difficult. Going forward may require in-depth participation from the chemical engineering discipline.
The new coke oven can also use the gas generated by coking to circulate and heat the furnace body, and at the same time, a part of the coal tar can be recovered. The tar, which is cooled and recovered with water, will be collected in clay pots and sealed, and become kerosene or other fuels, lubricants that replace animal fats, or some basic chemical raw materials. The service life of iron cannons is relatively low because they are naturally prone to rust, and maintenance is more troublesome. However, for Fei Qian, it has become a better choice.
After all, copper coins are still money today...
?? Cai He was so frightened that he was almost blinded by Fei Qian''s aura. He immediately lowered his original expectations again and again, almost holding Fei Qian''s thigh and crying and praying...
??If you leave Cai He in Chang''an for the time being, turn your head and start flipping the map to check the future opponents of Fei Qian and other building ships in Jiangdong, you will find that Emperor Sun is actually very sad at the moment.
???????????????????????????????????????????????????????????????????????????????????????di
This is quite embarrassing.
?Sun Quan actually wanted to carry out a series of reforms in Jiangdong.
??If the noble gentry of the Han Dynasty have influenced the court in many places, then in Jiangdong these noble gentry and local gentry have not only influenced, but even determined various strategies of Jiangdong.
?Sun Quan attempted to get rid of these Jiangdong clans, and then divide the counties and counties into separate systems, open up channels of speech, exercise the rule of law, and handle local affairs in accordance with the laws of the country instead of being controlled by the clans in the countryside. There is actually nothing wrong with this series of actions. If Sun Quan really does it, Jiangdong will become rich and powerful.
?But Sun Quan was too impatient and immediately took over the land and military power.
Sun Quan rectified the land administration, sent poor people and clerks to various places to check the amount of land, and began to limit the number of private soldiers. Such measures were obviously beneficial to the overall situation of Jiangdong, but they would seriously infringe on the interests of local nobles.
As a result, inevitable conflicts broke out.
??Jiangdong''s internal chaos suddenly arose, rebels were everywhere, and South Vietnamese were causing trouble everywhere. These Jiangdong nobles owned land, population, wealth, and private soldiers. When these things were brought together, they formed a very powerful force that was enough to overturn the Sun family''s foundation.
There was originally a rift in the Sun family...
In fact, no matter what Sun Quan did, it was useless to defeat Liu Biao or Cao Cao, because the people in Jiangdong would not give in because of certain achievements. Just like the Chu State in history, they once had a huge land. , once ruled the king and hegemony, but under the obstruction of the big nobles in the country, the reformers of Chu State did not end well. They were murdered and exiled. Basically, they all ended in tragedy.
??If Mrs. Wu had not died, Sun Quan felt that he still had support, and there would have been a huge dispute in Jiangdong...
?Sun Quan knew that although Zhou Yu usually talked about it and even despised his own stupidity and short-sightedness, he would still sacrifice himself as long as he really encountered any danger.
As for Zhang Zhao, Zhang Hong and others, they are just outsiders, so as long as Sun Quan gets the support of his mother, then the Wu family relatives represented by his mother will naturally be basically on his side. In this way, as long as When the Sun family''s foundation is really in danger, Mrs. Wu and Zhou Yu will join forces and go on a killing spree...
?Hence, Sun Quan is not afraid.
Children with mothers are bold.
Because he knows there are still people who love him.
?After his mother died, Sun Quan became afraid.
When there are parents, brothers are brothers and they still have a unified place of origin. But when there are no parents, brothers may not be brothers because they only have different destinations. This may be true between brothers, let alone other relatives of the Wu family who don''t have much family ties?
The ruthlessness and tolerance in the Sun family made Sun Quan make an important decision. It was also the decision that made him look the most timid, but also the smartest. He handed over the political power and divided it into two. The military power was given to Zhou Yu. Government affairs were given to Zhang Zhao.
?Then Jiangdong stabilized instantly...
With Zhou Yu and a group of uncle-level veterans sitting in charge, carrying big sticks and swinging them around, no one in Jiangdong dared to move rashly.
Zhang Zhao on the other side was responsible for dividing the carrots, and discussed the contents originally formulated by Sun Quan that made the Jiangdong nobles feel uncomfortable. Most of them were overturned, and a few were left. Of course, more were still in place. A face-saving project...
For example, private soldiers.
It is now clearly stipulated that "private soldiers" are not allowed.
But there is no rule against having "housekeepers".
??My "servants" like to wear armor and have swords and guns on them. I''m happy with that. Is there any problem?
It is stipulated that no more than 500 armed persons are allowed in a manor, so that means 499 people per manor...
Zhang Zhao laughed, and everyone laughed too.
Sit in rows and eat fruits.
In such a comfortable and peaceful atmosphere, Jiangdong''s economic development is surprising. The rebellious people who had been summoned before returned to the fields again. Agriculture has recovered, handicrafts have also recovered, and the economy has improved. Jiangdong''s fiscal deficit has also been greatly alleviated. As long as nothing unexpected happens, Jiangdong will be able to It’s sure to be a good year.
?Things are sometimes so weird. Sun Quan desperately wanted to control Jiangdong, but Jiangdong was in chaos. But now that Sun Quan has given up, Jiangdong has developed agriculture and mulberry trees, and the economy has prospered.
I don’t know if it’s because the Jiangdong nobles want to explain something through this current situation. Anyway, Jiangdong’s momentum is extremely good...
Under such a good situation, Yujiang visited Sun Quan.
?Sun Quan was on the mountainside, keeping filial piety for Mrs. Wu.
There are soldiers of the Sun family at the foot of the mountain and on the surrounding mountain tops, but they will not come up to this mountain unless there are special circumstances, because the entire mountain is the tomb of Mrs. Wu, and in Mrs. Wu’s grave Next to the tombstone is Sun Quan''s temporary residence, a simple courtyard.
Simple wooden house, a small yard with not too flat soil, surrounded by a simple and rough fence as a wall.
There are some vegetables grown in the courtyard.
?Sun Quan was like an old farmer, wearing linen clothes stained with mud.
Zhou Yu first paid homage in front of Mrs. Wu’s tombstone, and then went to Sun Quan’s courtyard and sat on the wooden floor of the front hall in front of the wooden house. “My lord, this place is quite clean...”
?Sun Quan nodded slightly. There was no hatred, no anxiety, no resentment in his eyes, but they were not numb, just like a calm mountain pool, deep and deep.
Sun Quan now moves less, laughs less, and cries less. Except for going to Mrs. Wu''s tomb regularly in the morning and evening every day, he seems to be in a daze the rest of the time.
Looking at the sunny sky, watching the cloudy sky, watching the clouds rolling and relaxing, watching the rain stop and the clouds disappear.
Watching the rain fall from the branches, watching the leaves wither with the cold wind.
?Ever since he ascended to the position of Lord of Jiangdong, he has never stopped, and now that he is far away from the hustle and bustle, he can really look at everything around him.
Zhou Yu looked at Sun Quan, and finally saw that Sun Quan no longer had any hairiness, but began to look like a sword hidden in a scabbard, with no brilliance exposed, but hidden sharpness.
?Zhou Yu sat on the side of Sun Quan and slowly described the current situation in Jiangdong.
Zhou Yu is not showing off, but just describing.
Sun Quan listened silently, with neither anger nor sadness on his face.
After Zhou Yu finished speaking, he stood up and said he would come back next month. He did not ask Sun Quan for his opinion, nor did he express his desire to hear Sun Quan''s thoughts.
Sun Quan also got up and sent Zhou Yu off.
Outside the fence of the small courtyard, Zhou Yu paused briefly and said goodbye to Sun Quan.
?Sun Quan nodded, and then when Zhou Yu turned around to leave, he said: "I see that the governor has a little gray hair on his temples. Please take care of yourself and don''t overwork yourself..."
Zhou Yu nodded, smiled, and left.
?Sun Quan stood on the mountainside and watched Zhou Yu go away. He didn''t know that Jiangdong''s model of "governing by doing nothing" happened to be in line with the prototype of "governing by decentralization", so it showed temporary prosperity.
But the current political model in Jiangdong is not mature.
?Sun Quan just understood that beneath the temporary prosperity on the surface, there was still a turbulent undercurrent lurking.
