The construction of Tianjin Bridge has been completed, and Shao Shude came to the scene to attend the ceremony.
The bridge is located in the north of Shangshanfang, across Luoyang, and leads directly to the imperial city. Officials living in the outer city mostly have to pass through this bridge when going to court, so it is very important.
Shangshanfang is also the last lane on the first street of Dingdingmen East. The street has six lanes, namely Mingjiao, Yiren, Chunhua, Anye, Xiuwen and Shangshan.
Shangshanfang is also a place where dignitaries and nobles live together. Because it is close to the imperial city, it is convenient to go to court.
At this time, due to its location advantage, it is still a popular residential area.
Xue Wangye's residence, originally the residence of Princess Taiping, was rebuilt and given to his eldest daughter Shao Guoer by Shao Shude. This is a mansion that even his own daughters would envy.
The loyal residence of Ashina, the general of You Xiaowei, was rebuilt and given to Liang Hanyong.
The couple actually have two mansions in Shangshanfang, which is a great coincidence.
The second daughter, Shao Mu, is seventeen years old and is about to get married. She also has a house, the Wu Sansi House, which is under construction.
The eastern capital was left behind, the capital was on defense, the capital was escorted to the government office, and the capital was also the governor of Yu. Zhang Jun's house was given to Qi Binzhang, the secret envoy of Bei Ya, and was also rebuilt.
The former Sui Dynasty general Yongkang Gong Li Yaowang's old residence is also being cleaned up, and it is planned to be given to Gao Renhou after it is built.
The gathering of dignitaries and the huge population's demand for commercial transportation made the construction of Tianjin Bridge a key project.
In fact, Tianjin Bridge is just a general term.
The Luoshui River is divided into three branches here, with the main river channel in the middle and a stone bridge on the river, called "Tianjin Bridge".
The bifurcated river on the north side is called "Huang Dao Canal", and the bridge on the river is called "Huang Dao Bridge".
The bifurcated 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 Republic of China, the Tianjin Bridge was one of the famous attractions in Luoyang, and was known as the "Tianjin Dawn Moon". On both sides of the bridge, merchant ships were parked at the docks. On the river bank, merchants from all over the world were bustling, and the shops were lined up row upon row, making it very prosperous.
.
Nowadays, Tianjin Bridge has been rebuilt with great efforts, but the grass on both sides is obviously not as lush as it was back then, and it is still slowly recovering from the destruction.
The New Tianjin Bridge is an arch bridge, and its materials are stone, bricks, and wood.
The design of this bridge actually started more than a year ago. The reason why it took so long was because Shao Shude was "nosy".
He requested that the bridge be built very high and the bridge arches enlarged. There was no ready-made style for reference, which made the craftsmen from Chang'an very troubled.
Moreover, Shao Shude specifically requested that a "design plan" must be prepared and presented to him.
It is really rare to have a design plan for building a bridge, at least it has never been heard of by craftsmen. They can't draw or write, they only know how to work, what should they do?
In the end, the Imperial College got involved. Both parties worked together to design and come up with a plan.
It's not that Shao Shude deliberately made things difficult for them, but that he wanted to promote standardization and scientificization in the field of engineering construction. He repeatedly verified and determined the design plan in advance. Once the plan is finalized, you cannot do whatever you want, and you must strictly follow the drawings.
Admittedly, this is not very convenient. Historically, construction has been done here, there, and finally made up. Even for large projects like Shangyang Palace, Gaozong Dynasty did not have a design plan when it was built. The maps archived in Chang'an,
It's still a painting after it's finished. It doesn't have the size or the amount of materials used, so it's just a confusing picture.
The main purpose of Shao Shude's request for a design plan for the Tianjin Bridge was to promote a standardized behavior. This is an idea and a rule. He has wanted to establish this rule for a long time.
In the second half of last year, the design plan was finally officially released. Master Mani from the Imperial Academy led a group of students and worked closely with the craftsmen to compile several thick stacks of drawings.
It is worth mentioning that important drawings of the state and dynasty are usually drawn on relatively thick paper. The drawing tools used are not brushes.
The most commonly used one is the earth pen. This kind of pen is divided into two types. One is made of graphite and other substances mixed with glue, mixed and rolled into strips, and then painted; the other is made of soil suspected of being a natural pigment, fixed on a wooden pen holder.
Painting.
After earthen brushes, there are also hard brushes such as reed tube brushes and bamboo cone brushes, which are dipped in ink for painting.
These hard pens are generally used in murals and sculptures, and are still very common.
After the design plan came out, Shao Shude came to "torture" them again, directly interrogating their souls: Why do you think this design plan will not cause problems? What is the basis? I can't say that it was like this before, and I was like this too. You have to tell me the real
s reason.
Master Mani is still very good at fighting. He starts with geometry and talks about force.
He now also knows the concepts of component force, resultant force and direction of force, and he can explain it 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 was very shallow, so he had no choice but to find a place to build a scaled-down version of the stone bridge and conduct experiments.
Only then did Shao Shude laugh. He knew that just doing experiments would be enough. Quantitative things are all achieved through experiments. Summarizing through experiments and then refining the theory is the right way.
"Master, do you now know that moving carriages and horses have a greater impact on the bridge than standing still?" Shao Shude asked, looking at the brand new Tianjin Bridge.
"Yes." Master Mani lowered his head and said.
Big is definitely big, how big is it? Can it be quantified? It doesn’t need to be precise, but it needs to be roughly known.
Shao Shude suggested that the unit of force is "ox", which is in line with people's understanding. But you need to specify how many are counted as one ox. Currently, Guozixue uses a standard-sized stone to define it, which is a bit rough and not very precise.
But it can already play a big role.
Take this Tianjin Bridge for example. Originally you didn't know the difference in load caused by a fast-moving carriage and a stationary carriage. But now through continuous experiments, you have a vague number, so you don't have to worry about the bridge as before.
Destroy and desperately pile up materials, saving too much money.
Quantitative analysis, this is what Shao Shude has always insisted on, and has created many new concepts for this purpose, such as cattle.
"Actually, there is one more thing." At this point, Shao Shude sighed and said: "I asked people to record the amount of rain around Luoyang before, but I forgot to ask people to measure the wind speed. Wind also affects the bridge. But forget it, this kind of
Xiaoqiao, the impact is not big, anyway, you just need to remember that it has such an impact."
Master Mani's eyes widened. Is the Tianjin Bridge still small? If it were bigger, he wouldn't have the confidence to build this kind of bridge. I'm afraid he would have to build a floating bridge.
"Have you figured out which parts of the masonry stacking bear the least stress and where the joints can be located?" Shao Shude asked again.
"It's clear." Master Mani said: "This was proposed by the Chang'an craftsmen. They have not done any experiments, but they know that if one third of a piece of brick is taken, it is the joint. They don't know that this is the point with the least force.
But I just know what to do.”
"Have you done experiments to confirm it?" Shao Shude asked.
"proved."
"Okay." Shao Shude nodded happily and said: "In my lifetime, all construction projects must have a design plan, a stress analysis, and an estimate of how much material to use, what kind of materials, and how much money it will cost.
Geometry. If you don’t understand, do the experiment immediately. Do the experiment, do the experiment, do the experiment again, remember this.”
He is now very worried that after his death, these things will cease to exist.
Although scientific construction technology can greatly save national financial investment, what if you encounter an owner who does not want to save money? Among the construction costs, a lot of manpower and materials are actually obtained through corvee labor. For officials,
This kind of cost is not sensitive, and they have no desire to save money, because the people's power seems to be infinitely exploitable.
He is now thinking of ways to ensure that scientific construction techniques can be passed on and not disappear.
This is not only a matter of the building itself, but something deep within it that Shao Shude wants people to get used to, that is, scientific analysis methods, through establishing units, designing experiments, and conducting quantitative analysis.
If we can achieve this step, we are 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 ultimately lifeless. There is a high probability that people will perish and governments will cease to exist. How to avoid this?
?
After much thought, he had only one solution: 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 basis for their livelihood, their breadwinner, and even a tool for gaining profits, otherwise they will not have the motivation to maintain it.
Industry monopoly associations? It sounds a bit reactionary and hinders technological progress. But everything has advantages and disadvantages. The advantage of industry monopoly associations is that they can preserve and pass on knowledge as much as possible, although most of them are limited to masters and apprentices, fathers and sons, and father-in-law. Because
There are real interests involved.
What he wants now is to pass on knowledge. He has no control over whether it can progress or not, and he has no ability to do so.
In addition, it is time to expand the enrollment of Guozixue. Train more people and spread knowledge to the people. Officials are not sensitive to costs, but private projects will still be considered, which can play a more or less role.
People with knowledge must be given benefits, and they must live a decent life and have social status, so that they can pass on the knowledge and spread the fire to all parts of the country as much as possible.
There is no benefit, only ghosts come to learn this thing, even if it is a scholar appointed by the "Great Xia Taizu".
"Let's go, I want to go to Guozixue." Shao Shude said.
This sentence was addressed to Li Yixian. After hearing this, he immediately organized Sergeant Yin Anzhi to clear the way.
The officials and people who were watching the excitement dispersed immediately, but they still gathered around Tianjin Bridge, pointing, talking and laughing.
The construction of a bridge is nothing to the whole of Luoyang and even the whole world.
But at a time when there is only destruction but no construction, this kind of project brings hope to people.
