Late Tang Dynasty Floating Life

Chapter 1007 Tianjin Bridge

The Tianjin Bridge has been built, and Shao Shude attended the ceremony in person.

The bridge is located in the north of Shangshanfang, across Luoyang and directly to the imperial city.Most of the officials living in the outer city pass through this bridge when they go to court, so it is very important.

Shangshanfang is also the last one on Dingdingmen East First Street.There are six squares in this street, namely Mingjiao, Yiren, Chunhua, Anye, Xiuwen and Shangshan.

Shangshanfang is also a place where dignitaries live together, because it is close to the imperial city and it is convenient to go to court.

At this time, because of the location advantage, it is still a hot residential area.

Xue Wangye's residence, originally Princess Taiping's residence, was given to his eldest daughter Shao Guoer by Shao Shude after reconstruction. This is a mansion that even his own daughter envies.

The loyal residence of General You Xiaowei, Ashina, was rebuilt and given to Liang Hanyong.

The couple actually had two mansions in Shangshanfang, which can be called a prosperous encounter.

The second daughter, Shao Mu, is 17 years old and is about to get married. She also got a house, Wu Sansi House, which is under construction.

The residence of Zhang Jun, who stayed behind in the east, defended in the capital, served as the yamen of the capital and was also the Marquis of Yu, the official of Zhengyi, and the guest of the inspector prince, was given to Qi Bizhang, the privy envoy of the North Yamen, and it was also rebuilt.

The old residence of Li Yaowang, Duke of Yongkang, the former great general of the Sui Dynasty, was also being cleaned up, and he planned to give it to Gao Renhou after it was completed.

The gathering of dignitaries and the large population's demand for commercial transportation made the construction of Tianjin Bridge a key project.

In fact, Tianjin Bridge is just a general term.

Luoshui is divided into three streams here, with the main channel in the middle, and a stone bridge over the river, called "Tianjin Bridge".

The bifurcated river on the north side is called "Zhuangdao Canal", and the bridge on the river is called "Zhuangdao Bridge".

The forked river on the south side is called "Huangjin Canal", and the bridge on the river is called "Huangjin Bridge".

The three bridges are collectively called Tianjin Bridge, but they were actually built in three sections. A pavilion was built on the sandbar in the middle of the river for pedestrians to rest.

In the early years of the Guo Dynasty, Tianjin Bridge was one of the famous scenic spots in Luoyang, and there was a saying of "Tianjin Xiaoyue".On both sides of the bridge, merchant ships are moored at the pier.On the river bank, merchants from all over the place are bustling with each other, and the shops are row upon row, very prosperous.

Now Tianjin Bridge has been rebuilt with great effort, but the grass on both sides is obviously not as good as it was then, and it is still in the slow recovery after the destruction.

The New Tianjin Bridge is an arch bridge made of stone, brick and wood.

In fact, the design of this bridge started more than a year ago, and the reason why it took so long is because Shao Shude was "problematic".

He demanded that the bridge be built very high, the arches of the bridge became larger, and there was no ready-made model for reference, which made the craftsmen from Chang'an very troubled.

Moreover, Shao Shude specifically requested that there must be a "design plan" and submit it to him.

It is really rare to see such a thing as designing a plan to build a bridge, at least the craftsmen have never heard of it.They don't know how to draw or write, they only know how to work, what should they do?
In the end, it was Guozijian who got involved.The two sides worked together to design and come up with a plan.

It wasn't that Shao Shude deliberately made things difficult for them, but he really wanted to promote the standardization and scientificization of the engineering construction field.Repeated research in advance to determine the design plan.After the plan is finalized, you can't do whatever you want, you must strictly follow the drawings.

Admittedly, this is not very convenient.In the past, when building, it was done here, there, and finally improvised.Even for such a large project as Shangyang Palace, the Gaozong Dynasty did not have a design plan when it was built.The illustrated books archived in Chang’an are still paintings drawn after completion, neither in size nor in the amount of materials used.

The main purpose of Shao Shude's request for a design proposal for the Tianjin Bridge is to promote a standardized behavior.This is a kind of thinking, a kind of rule, he has wanted to establish this kind of rule for a long time.

In the second half of last year, the design plan was finally officially released.Master Mani of the Imperial College led a group of students and worked together with the craftsmen to compile several thick stacks of drawings.

It is worth mentioning that the important books of the country and dynasty are generally drawn on relatively thick paper.The drawing tool used is not a brush.

The most commonly used is the clay pen.There are two types of this kind of pen. One is to mix graphite and other substances into glue, knead it into strips after stirring, and then paint;

After the soil brush, there are also hard brushes such as reed tube brush and bamboo cone pen, which are dipped in ink for painting.

These hard pens are generally used in the drafting of murals and sculptures, and they are still very common.

After the design plan came out, Shao Shude came to "torture" them again, and directly tortured his soul: Why do you think that this design plan will not cause problems?What is the basis?It cannot be said that it was always like this before, and I am also like this. You have to tell me the real reason.

Master Mani is still very good at fighting. He started from geometry and talked about force.

He now also understands concepts such as component force, resultant force, and direction of force, and he speaks clearly and logically.

Shao Shude asked again, why are you so sure that this kind of bridge can withstand such a force?

Master Mani's theoretical knowledge is very shallow, so he had no choice but to find a place to build a stone bridge in scaled down version for experimentation.

Only then did Shao Shude laugh, knowing that it would be good to do the experiment.Quantitative things are all done through experiments. It is the right way to summarize and summarize through experiments, and then refine theories.

"Master, now you know that moving chariots and horses will have a greater impact on the bridge than standing still chariots and horses?" Shao Shude asked looking at the brand new Tianjin Bridge.

"Yes." Master Mani bowed his head and said.

Big is sure, how much bigger?Can it be quantified?It doesn't need to be precise, but you need to know roughly.

Shao Shude suggested that the unit of strength is "bull", which is in line with people's understanding.But you need to stipulate that how much is considered a cow.At present, Guozixue uses a stone of a standard size to define it. It is a bit rough and not very precise, but it can already play a great role.

For example, on the Tianjin Bridge, you didn't know the difference in load between a fast-moving carriage and a stationary carriage.But now through continuous experiments, there is already a vague number, so there is no need to worry about bridge damage as before, and pile up materials desperately, saving too much money.

Quantitative analysis, which Shao Shude has always insisted on, has created many new concepts for this, such as cattle.

"Actually, there is one more thing." Speaking of this, Shao Shude sighed, and said: "Before I had someone record the amount of rain around Luoyang, but I forgot to have someone measure the wind speed. The wind also affects the bridge. But forget it, this kind of Xiaoqiao, it doesn't have much influence, anyway, you just need to remember that there is such an influence."

Master Mani's eyes widened, Tianjin Bridge is still small?No matter how big it is, he doesn't even have the confidence to build this kind of bridge, and he is afraid that he can only build floating bridges.

"Pile up bricks and stones, where the force is least, and where the joints can be located, have you figured it out?" Shao Shude asked again.

"It's clear." Master Mani said, "This was proposed by the craftsmen of Chang'an. They didn't do any experiments, but they knew that a piece of bricks and stones, taking one out of three, was the joint. They didn't know that this was the place where the force was the least. But you just know what to do.”

"Have you done experiments to confirm it?" Shao Shude asked.

"proved."

"Okay." Shao Shude nodded gratifiedly, and said: "As long as I live, all construction projects must have a design plan, a force analysis, and an estimate of how much material to use, what kind of material, and how much money will be used. Geometry. If you don’t understand, do the experiment immediately. Do the experiment, do the experiment, still do the experiment, remember this.”

He is very worried now that after his death, these things will disappear.

Although scientific construction technology can greatly save the country's financial investment, what if you meet someone who doesn't want to save money?Among the construction costs, a lot of manpower and materials are actually obtained through corvee.For officials, this kind of cost is not sensitive, and they have no desire to save money, because it seems that people's power can be extracted infinitely.

He is now trying to find a way so that the scientific construction technology can be passed on and will not disappear.

This is not only a matter of the building itself, but also something that Shao Shude wants people to get used to, that is, the scientific analysis method, through the establishment of units, design of experiments, and quantitative analysis.

If this step can be achieved, then it is not far from refining the theory.

This is what he wants to promote day and night, but unfortunately there is no soil for this kind of scientific seedling to survive at this time.Things promoted by his personal will are lifeless after all, and there is a high probability that people will die and the government will die. How to avoid this?

After thinking about it, he has only one trick: create an interest group and let it spontaneously maintain this kind of knowledge full of logical thinking and scientific analysis attitude.

This kind of knowledge must be the foundation of their livelihood, a food guy, or even a tool for profit, otherwise they will not have the motivation to maintain it.

Industry Monopoly Association?It sounds a little reactionary, and it hinders technological progress.But everything has advantages and disadvantages. The advantage of industry monopoly associations is that they can preserve knowledge and pass it on as much as possible, although most of them are limited to master-student, father-son, and son-in-law because of the real interests involved.

What he wants now is to pass on the knowledge. He can't control whether it can improve or not, and he has no ability to control it.

In addition, it is time for Guozixue to expand its enrollment.Cultivate more people and spread knowledge to the people.Officials are not sensitive to cost, and private projects will still be considered, which can play a more or less role.

People with knowledge should give them benefits, let them live decently and have social status, so that they can do a good job of inheritance and spread the fire as much as possible to all parts of the country.

There is no benefit, only ghosts come to learn this thing, even if it is a famous student hand-picked by the "Great Grandfather of the Xia Dynasty".

"Let's go, I'm going to Guozi Academy to have a look." Shao Shude said.

This sentence was said to Li Yixian, after he heard about it, he immediately organized the silver saddle sergeant to clear the way.

The officials and common people who were watching the excitement dispersed immediately, but they still gathered around the Tianjin Bridge, pointing, talking and laughing.

The construction of a bridge is nothing to the whole Luoyang and even the whole world.

But at a time when there is only destruction but no construction, this kind of engineering brings hope to people.

Confidence is more precious than gold.

People need hope.
