Chapter 3971: design

While Chen Xi and the others were talking about Sun Gan and the others, Sun Gan, who was building a road in the south of Yizhou, also encountered some troubles, but then again, this was in Chen Xi and others' expectations.

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.

Those who are willing to come to work, whether young or old, will sign a work contract for another five years. During the second phase, they may only have the chance to go home once or twice a year. This is a joke. Reasons for a lot of work to go home.

Of course, this is not Sun Gan’s improper person, but a way to calm people’s hearts. It is very important to have a stable job guarantee these years. This means that life can continue in a stable and stable way. So before the long vacation, give such a The notification is also to make these people feel at ease in the place, and when the time is up, they can return to work with peace of mind.

At the time of the Chang'an dynasty discussion, there were actually three things for Sun Gan. Ten years ago, Yuanfeng completely penetrated the road from Chang'an to the Ganges, dealt with the Qiang people in the Qinghai-Tibet area, and pretended to be repairing the road into Qinghai-Tibet. As well as entering the southwest of Yizhou, while linking the local roads, the local clan’s villages and villages were completed.

These three things are very important. In the second one, Sun Gan has already completed. He received a batch of young people of appropriate age from Chen Xi. After being included in the training, he arranged two teams for Sima Lang and Zhang Ji. Building bridges and repairing roads, good at designing and planning, can train the next generation of road builders for the elderly. In short, the rest depends on drawings and flickers.

After all, Sun Gan didn't want to build roads in the Qinghai-Tibet area at all before, because the technical strength was really not up to it. Although hardly speaking, it could be done with a certain loss, but Sun Gan really didn't think it was worth it.

That's why I had the idea of ​​sending a few teams of old people to Sima Lang and Zhang Ji to fudge, but Sima Lang already knew the true situation of the matter. Faced with the experienced old man arranged by Sun Gan, he decisively changed hands to Zhang. now that.

Because Zhang Ji lacked experience in this area, he always thought that he could do it. So after the old man arranged by Sun Gan and the old man who changed hands by Sima Lang arrived, he began to take the Qiang people to the vigorous road construction plan.

On the other hand, it is because the Qiang people really don't understand, and it is because they really don't understand, so the Qiang people will want to kill Sima Lang.

However, according to the current development method, Zhang Ji may quickly become the second target of the Qiang archer. From a certain angle, it can be regarded as seeking benevolence and benevolence.

Of course, Sun Gan didn’t take these trivial matters into his mind. What Sun Gan wanted to say now is what he used to be so-called in-depth, but he hasn’t seen anything in these years. The place where he builds roads is often unpopulated. place.

But generally speaking, after the repairs are completed, it will not take long. When the local villages are combined for planning, they will move the villages to both sides of the road as much as possible. Therefore, Sun Gan usually goes into no man’s land while working. But after he left, a village was left behind.

This is also the reason Sun Gan’s reputation is very good, and the counties and counties give Sun Gan a lot of face. After all, this man does practical things and leaves behind things that are largely convenient for the people, so the reputation has always been very good. , Even if there is some conflict with the local area in the early stage, it will be fine later.

"How certain is the situation?" Sun Gan greeted the head of his engineering team.

Tianbian is a comprehensive test for all kinds of things. Even after the two super-large palaces of Vientiane Shrine and Tianzhitang, Wei also asked the princess to stay in Weiyang Palace temporarily, which was designed by the Wei family. After checking with the construction staff, you can live again.

The same problem exists on Sun Gan's side. There is no need to worry about the roads, but that kind of large mountain viaduct needs to be overhauled and maintained after the sky has changed.

This is why Sun Gan’s road and bridge construction in the south of Yizhou has basically not continued to extend south since he left Chang’an. After the sky has changed, Sun Gan was forced to construct before overhauling one by one, considering the circumstances of his own design. viaduct.

However, compared with other places, the situation of the viaduct on Sun Qian’s side is much better. After all, Sun Qian left a great design margin when it was built. The etching technology is more as an aid, relying on machinery as much as possible. Structure to complete the construction of the bridge.

To put it simply, the viaducts built in the south of Yizhou can be supported by themselves even without the aid 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, and each bridge is reviewed by the third to the fourth team. It can ensure that the structure of the bridge is sufficient for support under the current environment. It is only a problem with the etching technology. After that, the design margin declined.” A leading technician explained with strong confidence.

When this group of people was building the bridge, the design margin was very sufficient. Although they did not foresee the change of the sky at the time, they made a great design margin based on the safety considerations of planning and design, so even if it is After the sky 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 the overload, their axles and frame can load 100 tons. Under the above conditions, it runs smoothly at the speed of the standard load, and even the braking distance will not be too different from the standard load.

The ghost knows what they thought when they were designing. Even if it’s the so-called lightweight, lightweight frame and the like, the actual load still far exceeds the standard load they entered. It may be because everyone knows it. .

Similarly, because 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. After all, if the bridge collapses and there is no car at all, then the Cambridge company will be crazy Despised.

Although logically speaking, the car company that crushed the bridge is also a representative of Tiankeng, but this kind of thing will be despised regardless of whether the bridge is justified or not, because people will always ask why this car is a There were so many bridges on the road, but none of them collapsed. Why did you walk to your house and the bridge collapsed? There is definitely a problem with your design.

In fact, how can I say that in later generations of viaducts and overpasses being crushed, those types of super-heavy trucks are involved. Basically, the bridge designers have no problems with the design. The bridges they designed can definitely bear their own The design margin of the submitted load is much higher than that of the load.

But it's useless. This place in China won't care about your beeping. If you break it, it must be your pit. Others have three times the margin, and yours is 1.5 times. It must be your fault...

What is unreasonable? This is unreasonable. In addition, even if it is so unreasonable, many people agree with it. Even the bridge-building circle will despise the design party of the broken bridge. No matter what the reason is, he has passed from me anyway. When the time comes, my bridge is not broken, yours is broken, then it proves that your design is inferior to mine, this is the iron proof...

This is all forced out. Although Sun Gan’s group of people does not have this way of thinking, they also realize that design is design and there must be a margin. It is best that the country requires only one-third of the upper limit of the design. , So there will never be an accident.

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

It does not mean that these bridges built by Sun Gan and others cannot be used without etching. In fact, even if there is no etching, these bridges are still the pinnacle of current architecture. The etching is only for higher strength. It is not that the current strength cannot be reached, so the design is forcibly completed by etching.

"The bridges that have been built before have no problems." After Sun Gan received a satisfactory answer, his heart was settled a lot, even if he thought that there should be no problems before.

After all, when Sun Gan was building the bridge, he had already relied on his own spiritual talent to simulate the design structure of the current materials in his thinking, and then enlarged the construction to reality.

It’s just that it’s better to be meticulous or meticulous for such major events.

"Then there are two aspects now. One is about etching. We will send people to research as soon as possible to quickly restore part of the etching technology. On the other hand, in the later construction process, do not use etching during construction. After the bridge is designed, the strength is corrected by etching." Sun Gan set the tone afterwards, and the other personnel nodded when they heard the words.

After all, I have suffered it once, and of course I don’t want to do it again, so I just rely on mechanical structure support when designing, at least the latter will not change with the change of the sky, not to mention they can’t rely on mechanical structure. Support bridge design.

"The other is about the clan in southern Yizhou. I think you all know that. Recently, you have been a little more careful. Let the workers put on armor and be prepared." Sun Gan saw this group of people listened to him. I began to mention another matter. The time for these clans in the mountainous area of ​​southern Yizhou to be cut off.
