technical type

When Master Ji thinks about the previous question again, he will think of Ji Mo's praise by the way. Nothing is more sincere than a child's praise. They will not know the hypocrisy and cunning of adults, and can express it more straightforwardly. inner feelings.

Unfortunately, Ji Mo is a fake child.

The highly praised Master Ji did not directly forget the topic of today's lecture. He was silent for a while, and after calming down, he continued his lecture. This time, it was not in the form of asking questions.

"There are many bridges over rivers, and bridges are also built to connect two mountains. The materials of bridges over rivers are nothing more than wood and stone, and their shapes can be divided into beams and arches. The length across the river can also be divided into large and medium. , Xiaosan, etc., this is a fixed bridge, if you want to move it, there are open bridges and pontoon bridges... There are also cable bridges, long cables across the river, which are more difficult..."

After talking about the types of bridges, Master Ji still has the face of an old farmer in the country, but when he talked about these, he was inexplicably motivated to give advice. In his own field, he It was the king, that kind of self-confidence gave him a sense of arrogance in his slightly hunched posture with his hands behind his back.

Ji Mo watched and listened, the knowledge points were increasing little by little. He knew a little bit, and the miscellaneous news scattered in daily life are being sorted out gradually at this moment, gradually sorted together, and after sorting, they are emptied out The vacancy was filled.

It is impossible to say that you don’t know anything about the existence of such a down-to-earth bridge as bridges. In modern times, who hasn’t seen ancient buildings? Haven’t there been one or two famous bridges in textbooks, and the name of the bridge? The story of the bridge builder?

It may not be systematically described, but if you are interested, just search for the top ten famous bridges outside of class, and you will definitely be able to see one or two classics from the text mixed with pictures.

Not to mention, these famous bridges that have been handed down for thousands of years are themselves famous scenic spots. During winter and summer holidays, come and have a look. There are inscriptions on the stone tablet, introducing the origin of the bridge. It focuses on construction skills, but there must be some related stories, whether true or not, telling the story of the difficulty of this bridge.

What kind of design condenses what kind of painstaking efforts, what kind of hardships and hardships make a bridge, and what kind of shape determines that it can exist for thousands of years...

Ji Mo still remembers the appearance of the classic side arch weight reduction. At that time, he just thought it was beautiful and novel. Let me feel the wisdom of the ancient working people. It is because of the good materials, the good shape, the incomparably solid foundation, and the correctly measured weight... Under the influence of many factors, there is such a famous ancient building, which will amaze the future generations.

Ancient measuring tools, if you say that Ji Mo didn’t have a concept before, but now after passing through so many ancient worlds, even if the worlds are different, the measuring tools are also different, but a certain standard of weights and measures, not to mention the outside, is still very standard in my place Yes, but what kind of complicated calculations do these standards have to go through, so that before a bridge is completed, you can already know where the load should be, where it needs to be reinforced, and where it needs to set up piers...

These, just thinking of the word "central angle", Ji Mo felt a sense of suffocation, how to measure the angle?

Do you really think that an arch bridge can be made by simply bending the wood and making the stone uneven?

In other words, it can indeed achieve a similar appearance, but it can really stand upright, just kidding, it doesn't need to be washed with water, and it will fall apart with just a touch.

There are also bridge piers, which are not difficult for ordinary people to think about—at least Ji Mo used to think that the laying of bridges is a very simple matter. Put concrete piers or stone piers in the river as bridge piers, and then put The length is just enough to reach the material of the bridge pier, whether it is wood or stone, it is laid flat on it and fixed, so that a flat bridge can be easily built.

This is very much like a game of building blocks. You don’t consider the possibility of sailing on the river, and you don’t mind how many more piers block the river, increasing the difficulty and cost of construction. You only consider simplicity. What could be simpler than this? ?

If it is a pontoon bridge, the problem of buoyancy and stretching must also be considered. The only way to build a bridge is to use almost no brains. Where it cannot bear load, just add a pier at the bottom. Where there is a problem, find some cement or some glue to make up for it just fine.

Can it survive the long years and wind and rain erosion, why bother to think so much?

If it is simpler, even the bridge deck is not needed, and a stone pier is placed in the water at intervals. This distance is the distance that people can cross their legs. It seems that there will be ones in many scenic spots, specially for tourists. Looking for a setting with the fun of the mountains, watching the children laughing and jumping over the stone piers and crossing the "bridge" smoothly, the water is also lively.

Unfortunately, no.

Water is the source of life.

Water is also the lifeblood, which determines the life of all people who rely on water.

For those boaters, those merchants, and those who rely on waterways to make a living, every additional stone pier in the river may affect more than one or two people's life and death.

"...every time it's time to build a bridge, people around will come to say hello..." Master Ji started talking, but he started to go off the rails. He talked about how much the people in the neighborhood valued the bridge, whether they supported the construction of the bridge, or didn't. Support, needless to say, the reason for the support is to connect the inside and the outside, so that their location will not be blocked, and it will be convenient to travel.

Reason for not supporting -

Ji Mo was surprised. He really couldn't think of the reason why he didn't support the construction of the bridge. It's like building a subway in a city. How many people don't want to pass by their homes for transportation?Prices can go up as a result!

As for some worries, such as noise disturbance, clutter, and so on, most of them are the worries of those old men and women who like to be quiet and conservative. They will inevitably have some incomprehensible complaints about the emergence of new things.

So, what can the bridge bring?

It is not an important traffic route, so there is no need to worry about the frequent traffic of vehicles and horses. In other words, the vehicles and horses at this time will not bring too much noise, but can bring a lot of money, like those who open farmhouses near scenic spots. If there are more people coming, there will naturally be people spending money for food and lodging.

There will be no one who will not buy a family hotel or something in a nearby cottage.

Lodging is a common thing in ancient times. The decent inns are all in the towns, but the towns are a minority, and the villages are the majority. People who come and go near the roads know how to knock on the doors of those villages to facilitate their own accommodation.

In a village, it is not uncommon for the village head to run around for this. This is a good thing that can make money while sitting.

"Why would you stop it?"

Ji Mo didn't understand, he tilted his head to look at Master Ji.

Master Ji smiled and said: "It depends on the situation. Some witches in the village say no. They are afraid of causing the water god to be angry and will no longer protect them..."

This is because they are afraid that mortals will offend the authority of the gods. --superstitious.

"Some elders in the village say no, they don't like outsiders coming here, and the bridge leads to the road, and someone must come over after it is built. These outsiders, they think it will bring bad things, and they don't want them to come here. arrival……"

It sounds stubborn and unreasonable, but it really exists. --conservative.

From another perspective, it seems more understandable. How do the elders maintain their authority? They are like their parents in the village. They say what they say, and those young people obey them because they are short-sighted, and the food they eat is not as salty as others. You have to obey, but if there are more people from outside and more knowledge from outside, how can they maintain their authority?

As long as there is a possibility of being offended, suppress it at the initial stage.Sensitive to asserting one's own power...

"Some are afraid of affecting their livelihood..."

This one is puzzling to Ji Mo. With more bridges and more outsiders, wouldn’t it be possible to develop a business of sitting on the ground and collecting money?Even if it is to collect bridge tolls, it is a good thing to make a steady profit without losing money. How can it affect the livelihood?

There are more ways to make a living, right?

"...They are afraid that the bridge pier will fall in the water, which will affect Fengshui and make it difficult to fish. Besides, if there is a bridge, the punters will not be able to make money here..."

Businesses in ancient times were suppressed, but that doesn't mean they didn't develop. All walks of life had a leader, such as the president of a chamber of commerce.

Even the punters, who pay protection fees on a daily basis, naturally have a circle. If many punters get together, they can drive the bridge builders out directly, and drive them to places they can't touch.

Free bridges, paid ferries.

As long as the former appears, how many people will seek the latter?

This is not the modern age with abundant materials. There are always some people who are willing to look for leisurely and ancient tastes. In ancient times, things that can save money are what everyone likes to see. No one would put away free ones and spend money instead.

Even the rich will only spend money for extra enjoyment. When they want to make a ferry, it must be the kind of exquisite decoration, even the comfort inside is worthy of their status, and most of these are their own. Do not mix with outsiders.

Those punters earn only a coolie's money, and they come and go with ordinary people. If there is a bridge, and even these ordinary customers are gone, it will really cut off the family's livelihood.

This is not an era where both men and women can make money. As the man who takes the lead in the family, if he can't make money, the whole family may starve to death.

This reason is enough for them to oppose the bridge.

On the one hand, it is the order of the government, and Master Ji has chosen a suitable place to build the bridge; on the other hand, it is the livelihood of many people, who may face the desperate situation of starving to death.

The contradictions in it actually existed, and in the face of these, Master Ji's choice was to change the location.

Ji Mo was surprised that he compromised so easily?Too... weak?Scared?

"Remember, when you build bridges in the future, you should also remember, don't spend time on these, the river is so long, you can always find a suitable place, if it really doesn't work, don't do it yourself..." Thinking of the third brother's legs No matter how it was broken, Master Ji would never ignore the viciousness of these ordinary people.

Why don't they know that it is an order from the government, but the poor will only make life difficult for the poor.
