While Chen Xi and others were talking nonsense about Sun Qian and others, Sun Qian who was building roads in the south of Yizhou also encountered some troubles, but having said that, this was also within the expectations of Chen Xi and others.

At the time of the Great Court Meeting, Sun Qian had to return to Chang'an because of the court meeting at the end of the fifth year of Yuanfeng, and distributed a large amount of supplies to all the workers, and signed a new long-term work contract with them, indicating that the first stage of work It ends here.

In the second stage, after the Great Court Meeting is over, those who are willing to come to work, no matter young or old, sign a five-year work contract. During this period, it is very likely that there will only be one or two chances a year to go home. This is just a joke. Great reason to work home.

Of course, this is not because Sun Gan is not a good person, but a way to calm people's hearts. It is very important to have a stable job guarantee these years, which means that life can continue steadily in the future, so before the long vacation, give such a The notification is also to let these people feel at ease in the place, and when the time is up, they can come back to work with peace of mind.

At the time of the court meeting in Chang'an, there were actually three things for Sun Qian. Yuanfeng completely penetrated the road from Chang'an to the Ganges ten years ago, dealt with the Qiang people in the Qinghai-Tibet area, and pretended to be repairing the road to Qingzhuang. , and entered the southwestern part of Yizhou, while running through the local roads, it completed the integration of local clan villages and villages.

These three things are very important. Sun Qian has already completed the second one. He received a group of young adults of the right age from Chen Xi. Building bridges and building roads, who are good at design and planning, can train the next generation of road builders. In short, the rest depends on blueprints and fooling around.

After all, Sun Qian didn't want to build roads in the Qinghai-Tibet area at all before, because the technical strength is really not up to the mark. Although it can be done with a certain loss, Sun Qian really thinks it's not worth it.

That's why he came up with the idea of ​​sending a few teams of old people to fool around with Sima Lang and Zhang Ji, but Sima Lang already knew the truth of the matter, facing the experienced old man arranged by Sun Qian, he resolutely handed it over to Zhang Ji. now that.

Due to his lack of experience in this area, Zhang always thought he could repair it, so after the old man arranged by Sun Qian and the old man transferred by Sima Lang arrived, he began to lead the Qiang people towards a vigorous road construction plan.

On the other hand, it was because the Qiang people really didn't understand, and it was precisely because they really didn't understand that the Qiang people wanted to kill Sima Lang.

However, according to the current way of development, Zhang may quickly become the second target of the Qiang people's eagle archers.

Of course, Sun Gan didn't take these little things to heart. What Sun Qian is going to say now is already so-called deep and barren, but he hasn't seen what happened to Sun Gan in these years. The places where he builds roads are often not even populated. place.

But generally speaking, it won't take long after the repair is completed. When the local villages are combined for planning, they will move the villages to both sides of the road as much as possible, so Sun Qian usually goes deep into no-man's land while working. But after he left, he left behind a whole village.

This is also the reason why Sun Gan has a good reputation, and the counties and counties in various places give Sun Gan a lot of face. After all, this person does practical things, and what he leaves behind is to a large extent convenient for the people, so his reputation has always been good , even if there are some conflicts with the local area in the early stage, they will get along well later.

"How is the situation confirmed?" Sun Qian greeted the head of his engineering team thoughtfully.

Tianchang is a comprehensive test for all kinds of things. Even after Tianchang, the two super-large palace complexes of the Vientiane Shrine and the Temple of Heaven, the Wei family first invited the eldest princess to temporarily live in Weiyang Palace. After inspection with construction personnel, live in again.

The same problem exists on Sun Qian's side. There is no need to worry about the roads, but the large mountain viaducts need to be repaired and maintained after the weather changes.

This is why Sun Qian’s road and bridge construction in the south of Yizhou has basically not continued to extend southward since he left Chang’an. viaduct.

However, compared to other places, the condition of the viaduct on Sun Qian’s side is much better. After all, Sun Qian left a huge design margin when it was first built. structure to complete the construction of the bridge.

To put it simply, the viaducts built in the south of Yizhou can support themselves even without the assistance of etching technology. The design structure is sufficient to support the span and self-weight of the bridge, and the maintenance is only for safety considerations.

"All our technicians have led the team down, and each bridge has been reviewed by three to four teams of personnel, which can ensure that the structure of the bridge is sufficient to support under the current environment, and there are only problems with the etching technology. Afterwards, the design margin declined.” A leading technician explained with strong confidence.

When this group of people built the bridge back then, they made a very sufficient design margin. Although they did not foresee the situation of changing the sky at that time, they made a huge design margin based on the safety considerations of planning and design, so even if it is After the weather has changed, their design is still safe and usable.

Just like some magical car companies and bridge construction companies in later generations, the standard load of these magical car companies is 30 tons, but if the country does not check for overloading, their axles and frames can carry a load of 100 tons. Under the above conditions, it runs smoothly at the speed of the standard load, and even the braking distance will not be much different from the standard load.

The ghost knows what they thought when they designed it back then. Even with the so-called lightweight, light-weight frame and the like, the real load still far exceeds the standard load they entered, probably because everyone knew it well. .

Similarly, bridge construction companies know that there are such a group of people. The design load of the bridge is different from the load they wrote on the bridge deck. After all, if the bridge collapses and there is nothing wrong with the car, the company in Cambridge will be mad contemptuous.

Although logically speaking, the car company that collapsed the bridge is also a representative of a tiankeng, but when this kind of thing is on the news, no matter whether the bridge repairer is reasonable or not, people will despise it, because there will always be people who will ask, why does this car fail? There are so many bridges on the road, but none of them collapsed. Why did they come to your house and the bridge collapsed? There must be something wrong with the design of your house.

In fact, in the incidents of viaducts and overpasses being crushed and collapsed in later generations, involving super-heavy trucks, basically the designers of the bridges have no problems in the design, and the bridges they designed can definitely bear their own The load presented may even have a design margin much higher than that load.

But it’s useless, this place in China doesn’t care about your beeping. If you break it, it must be your fault. Others have three times the margin, and yours is one and a half times. It must be your fault...

What is unreasonable, this is unreasonable, and even if it is so unreasonable, many people agree, even the bridge-building circle will despise the designer who broke the bridge, regardless of the reason, anyway, he passed by me Sometimes, if my bridge is not broken, but yours is broken, it proves that your design is not as good as mine, and this is the ironclad proof...

This is all forced out. Although the people under Sun Gan do not have this way of thinking, they also realize that design belongs to design, and there must be a margin. It is best for the country to carry only one-third of the upper limit of the design. , so nothing will happen.

After all, it is a super-large project, so when it was started, very in-depth research was carried out. Therefore, many of the etchings of the bridges in Yizhou were added after the later molding. The significance of these etchings is more in On the already high design margin, the design margin is further increased, but now there is no etching, but the design margin has come down.

It does not mean that these bridges built by Sun Qian will be unusable after losing the etching. In fact, even without etching, these bridges are still the pinnacle of current architecture. Adding etching is only for higher strength. It's not that the current strength cannot be achieved, so the design is forcibly completed by etching.

"As long as there is no problem with the bridge that has been built before." After Sun Qian received a satisfactory answer, he felt a lot more at ease, even though he thought there should be no problem before.

After all, when Sun Qian was building the bridge, he had already relied on his own spiritual talent to simulate the design structure of the current material in his mind, and then zoomed in and built it into reality.

It's just that for such a big matter, it's better to be more detailed.

"Then there are two aspects now. One is about etching. Send people to study as soon as possible to quickly restore part of the etching technology. Complete the design of the bridge, and then use etching to correct the strength." Sun Gan finalized the tone, and the other staff nodded upon hearing this.

After all, I have been through it once, and of course I don’t want to do it again, so it’s better to rely directly on the mechanical structure when designing, at least the latter will not change with the change of the weather, not to mention that they can’t do it by relying on the mechanical structure. Support bridge design.

"The other one is about the clans in the southern part of Yizhou. I think you all know that you have been more careful recently and asked the workers to put on their armor and get ready." I started to mention another thing. It is time for these clan forces in the southern mountainous area of ​​Yizhou to be cut off.
