While Chen Xi and others were talking nonsense about Sun Gan and others, Sun Gan, who built roads in southern Yizhou, also encountered some trouble, but then again, this was within the expectations of Chen Xi and others.

During the grand court meeting, Sun Gan 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 phase of work ended here.

When the second stage is over, those who are willing to work, whether they are young or old, sign a five-year work contract. During this period, there is a very likely time to go home once or twice a year. This is why they joked about a lot of work going home.

Of course, this is not because Sun Gan is not a human being, but a way to calm people's hearts. It is very important to have a stable job guarantee these days, which means that life can continue peacefully in the future. Therefore, before the long holiday, I would like to give these people a notice to stay at the place and wait for the time to come back to work with peace of mind.

When the court was held in Chang'an, there were actually three things for Sun Gan. Ten years ago, Yuanfeng completely connected the road from Chang'an to the Ganges, dealing with the Qiang people in the Qinghai-Tibet region, pretending to build a road to enter the green and strong, and entering the southwestern Yizhou. While connecting the local roads, he completed the merger of the local clans' villages and villages.

All three things are very important. The second one is that Sun Gan has completed it. He received a group of young and middle-aged people from Chen Xi. After it was included in the training, he arranged two teams for Sima Lang and Zhang Ji, who had rich bridge construction and road construction, good at designing and planning, and could cultivate the next generation of road construction personnel. In short, the rest was all based on drawings and deception.

After all, Sun Gan didn't want to build a road in the Qinghai-Tibet region at all before, because his technical strength was really not enough. Although it was hard to bear certain losses, it could still be completed, but Sun Gan really felt that it was not worth it.

Therefore, I had the idea of ​​sending several teams of old men to Sima Lang and Zhang Ji to fool him. However, Sima Lang already knew the truth of the matter. Faced with the experienced old man arranged by Sun Gan, he decisively transferred it to Zhang Ji.

Because Zhang lacked experience in this area, he always thought he could build it. So after the old man arranged by Sun Gan and the old man who had been transferred by Sima Lang arrived, he began to lead the Qiang people to a vigorous road construction plan.

On the other hand, it is because the Qiang people really don’t understand. It is precisely because they really don’t understand that the Qiang people want to kill Sima Lang.

However, according to the current development method, Zhang Ji may quickly become the second goal of the Qiang Man's The Legend of Condor Heroes. From a certain perspective, it can be considered as seeking benevolence and gaining benevolence.

Of course, Sun Gan didn't take these trivial things seriously. What Sun Gan wants to say now is already the so-called deep-dive. However, he has never seen what Sun Gan has done in recent years. The places where he built roads often have no place to even have people.

However, generally speaking, after the repair is completed, it will not take long to move the village to both sides of the road when the local village is being planned. Therefore, Sun Gan usually goes deep into the uninhabited area while working, but after he leaves, he leaves a village.

This is also the reason why Sun Gan has a good reputation and the counties in various places give Sun Gan a good face. After all, this person does practical things and leaves behind things that are very convenient and beneficial to the people. Therefore, his reputation has always been very good. Even if there are some conflicts with the local area in the early stage, he will have a good relationship later.

"How is the situation determined?" Sun Gan greeted his own engineering team leader.

The change of heaven is a comprehensive test for all kinds of things. Even after the change of heaven, the two super-large palace groups, the Viagra, asked the eldest princess to temporarily live in Weiyang Palace, and then live there after inspection by the design and construction personnel of the Wei family.

Similarly, there is such a problem here on Sun Gan, so there is no need to worry about the road, but the large mountain viaduct needs to be inspected and maintained after the sky changes.

This is why from leaving Chang'an to now, Sun Gan's road and bridge construction in southern Yizhou has basically not continued to extend southward. After the change of the sky, Sun Gan was forced to build the viaduct before repairing one by one when he designed it.

However, compared with other places, the overpass on Sun Gan’s side is much better. After all, when it was built, Sun Gan left a huge design allowance. The etching technology is more an auxiliary, and the construction of the bridge is relied on mechanical structures as much as possible.

Simply put, the viaducts built in southern Yizhou can still be supported even without the assistance of etching technology. Their design structure is enough to support the bridge span and self-weight of the bridge. The maintenance is only for safety considerations.

"All our technicians have led the team, and each bridge is reviewed by team three to four, which can ensure that the structure of the bridge is sufficient to support it in the current environment. However, after the etching technology problem, the design margin has declined." A leading technician explained with strong confidence.

When this group of people were building the bridge, they had sufficient design allowance. Although they did not foresee the situation of changes in the sky at that time, they made a huge design allowance based on the safety considerations of planning and design. Therefore, even if they were changed in the sky, their design was still safe and available.

Just like some magical car companies and bridge construction companies in later generations, the standard loading of these magical car companies is 30 tons, but if the country does not check for overload, their axle and frame can run smoothly at the loading speed with a loading capacity of more than 100 tons, and even the brake distance will not be much different from the standard loading.

Who knows what I thought when designing it back then? Even if it is used as the so-called lightweight, lightweight frame and other things, its real load is still far more than the standard load they entered, which may be because everyone knows it.

The same bridge construction company knows that there are such a group of people, the bridge design load is different from the load they wrote on the bridge deck. After all, if the bridge collapses and there is no car at all, the Cambridge company will be despised crazy.

Although logically speaking, the car company that crushed the bridge is also a representative of a sinkhole, in this kind of thing, no matter whether the bridge is built or not, it will be despised by people when it comes to news, because people will always ask why this car has walked so many bridges along the way but it has not collapsed. Why did it come to your house and the bridge collapse? There is definitely a problem with your design.

In fact, in the later incidents of overpasses and overpasses being crushed, the bridge design involved such super heavy trucks. Basically, there was no problem with the design of the bridge. The bridge they designed could definitely bear the load they presented themselves, and even the design allowance was much higher than that load.

However, it is useless. China won’t care about your whisper. If you break it, it will definitely be your pit. Others’ balance is three times, and yours is one or five times, it will definitely be your fault...

What does it mean to be unreasonable? This is unreasonable. In addition, even if it is so unreasonable, many people agree with it. Even the circle of bridges will despise the design party where the bridge is broken. No matter what the reason, anyway, when he passed by me, my bridge has not been broken, and yours has been broken, it proves that your design is not as good as mine. This is ironclad evidence...

This was all forced out. Although Sun Gan's men did not have this way of thinking, they also realized that design must be designed and the margin must be. It is best if the country needs to carry only one-third of the design upper limit, so that nothing will happen.

After all, it is a super-large project, so when it was started, it was conducted very in-depth research. Therefore, many of the etchings of bridges on Yizhou were added after being formed later. The significance of these etchings is more about the already high design margin, which further increases the design margin. Now etching is gone, but the design margin is just reduced.

This does not mean that these bridges built by Sun Gan and others will not be used after they are etched. In fact, even if there is no etching, these bridges are still the pinnacle of current architecture. Etching is only for higher strength, not that the current strength cannot be achieved, so the design is forced to be completed by etching.

"It's fine if there is no problem with the bridge that has been built before." After receiving a satisfactory reply, Sun Gan felt much more at ease, even though he felt that there should be no problem before.

After all, when Sun Gan was building the bridge, he had already relied on his own spiritual talent to simulate the current material design structure in his thinking, and then expanded it to reality year-on-year.

It’s just that such a big thing is better to be more meticulous.

"There are two aspects now. One is about etching. Send someone to study as soon as possible to quickly restore part of the etching technology. On the other hand, during the later construction process, do not use etching at first during construction. The bridge is completed by structural design, and then use etching to correct the strength." Sun Gan set the tone afterwards, and the other personnel nodded after hearing this.

After all, I have been hit once, so of course I don’t want to do it again, so I just rely on the mechanical structure to support me when designing. At least the latter will not change with the changes in the sky, not to mention that they cannot rely on the mechanical structure to support bridge design.
