Chapter 41 Beijing-University Railway

Yao Guangxiao walked silently, and even many people don't know that there is such a figure who is no longer in Beijing.

He Xi's mind was already on the Beijing-University Railway.

Ge Tiangong and Zhang Youzhi have been running back and forth many times on the road from the northwest to Dongsheng during this period of time, and I don't know how many times the inside of the thighs has been worn out. At this time, they also came to He Xi to restore their lives.

He Xi called Yang Shiqi, Xie Jin, Qu Tong and others over.

Ge Tiangong was in front of He Xi, but he was able to let go. It's just that his face is not good. He said, "My lord, I know that this thing is very significant, but this thing is really difficult to do." He doesn't come in vain.

Directly took out a paper tube from behind him, opened one end, and took out a long scroll from it, nothing else, it was a map, the map was very large, and it took two people to pull it open. However, the area represented by the map is not large. Only the railway from Beiping to Badaling to Xuanfu is planned.

In terms of route selection, there are some places like Zhan Tianyou's Beijing-Zhangjiakou Railway, and there are many places that are not the same.

After all, the support that Zhan Tianyou received was not the same as the support that Ge Tiangong received. When Zhan Tianyou was building the railway, he considered that there were too many things outside the railway, and all kinds of funds were very strict.

But Ge Tiangong is different here.

Money is not a problem here in Ge Tiangong, the most is He Xi's problem, Ge Tiangong only needs to quote an accurate number.

There is no limit to the problem of manpower.

If necessary, He Xi can let the active army put down the fire guns and go to build the railway.

It's just that they have the same problem. Even Ge Tiangong's problems are bigger than those encountered by Zhan Tianyou. Because in Zhan Tianyou's time, the Chinese were followers, and Zhan Tianyou learned the complete railway system in the West, even if some things could not be used on the Beijing-Zhang Railway, but at least a reference.

But Ge Tiangong's side is different.

The entire railway technology system was formulated by Ge Tiangong.

Zhan Tianyou's work on the Beijing-Zhangjiakou Railway was groundbreaking to a certain extent. But Ge Tiangong is here completely starting from scratch.

In the past, the Jingying Railway was almost all flat, even if there were some bridges, but where could it compare with the heavy rocks of Badaling. There are so many problems here.

Ge Tiangong said, "I went on a trip to Dongsheng. There are several difficulties on the railway from Beijing to Dongsheng, and the first difficulty is here, crossing Yanshan. The second difficulty is Yinshan, and the third difficulty is the Yellow River."

"But on the whole, you can only climb over Yanshan, and Yinshan is not a big problem, because Yinshan is much easier to deal with than Yanshan. As for the Yellow River, we will talk about it in the future. This is the best route I've chosen."

Ge Tiangong pointed to the map and followed the stations on the map. has been over Yanshan to Xuanhua, there are about eight or nine stations in total, but He Xi frowned.

This is a contour engineering drawing, of course, how much difference it is from the standard engineering map that followed, He Xi doesn't know. But now it is in the same vein as the military map, it is all taught by He Xi, and He Xi is very clear.

On this route, there are seven large and small bridges and eight tunnels, and the slope is very high in many places, and He Xi does not know the climbing ability of today's steam locomotives. But He Xi was worried.

Ge Tiangong said, "The first problem is the tunnel."

"There are no tunnels excavated on the Gyeongyeong Railway. Now tunnels have to be dug or hundreds of miles will have to be added. I thought about it, or digging a tunnel is still the fastest. Many of the mountains in Yanshan are dirt mountains, and they are also relatively easy to excavate. It's just that I really don't know the doorway here."

"It takes specialized people to do it, and one of the tunnels is more than a mile long, so you need to pay special attention."

He Xi said, "Specialized talents? Where can I find it?"

Ge Tiangong said, "The people who built the mountains for the imperial court. Presumably there are some means. And the people in the mines."

He Xi suddenly understood.

It was the craftsman who built the tomb of the emperor.

Although these workers

Craftsmen all dig holes in the ground, but there is no difference between digging holes in the ground and making holes in the mountains. As for the miners, it is even more of a profession. However, most of the minerals mined on a large scale today are open-pit mines.

After all, today's productivity, mining beneath the surface, is too costly. Some of the gains outweigh the losses.

However, that doesn't mean no one is doing such a thing. After all, if it is a precious mineral such as gold and silver, it is completely suitable.

He Xi also asked some miners if they had a good ability to make holes.

As long as it is useful for the construction of a railway for the imperial court, He Xi is willing to send someone to find it.

He Xi said, "I will send someone to deal with these people's affairs, and continue to speak."

"Yes." Ge Tiangong said, "Secondly, there is the bridge. Before Jingshi went to Yingkou, some bridges were also built. But it can't compare to the bridges here. Those were all flat ground to build bridges. It was built in the middle of the mountains, one of the most important bridges. It's right here."

He Xi looked at the contour lines piled up on the map, and said in a daze, "There is a drop of 100 zhang here?"

Ge Tiangong said, "Exactly." Immediately, Ge Tiangong took out a drawing from the back, and this map was a sketch of a bridge. When He Xi looked at it, he knew that something was wrong.

This valley is too deep. It's not easy to build bridges.

Although the span is not high, such a deep valley, with the technology of building bridges in this era, He Xi does not have much confidence. He Xi said, "Can't you change it here?"

Ge Tiangong said: "I also thought that this is already the best choice, otherwise it will not only be a bridge if it is built in other places, but also more than a tunnel."

He Xi said, "Do you have a solution?"

Ge Tiangong said, "I can only say one idea, I don't know if it's okay?"

He Xi said, "Say."

"I want to build a steel bridge," said Ge Tiangong.

He Xi looked at Ge Tiangong and secretly sighed that there are talented talents in every era, and Ge Tiangong did not leave his name at all in the original history. Now it seems that the engineers who built the railway in later generations will have to learn Ge Tiangong's works.

He Xi could understand Ge Tiangong's thoughts, but others were not quite able to understand them.

Seeing this, He Xi said, "Tell me in detail."

Ge Tiangong said, "I have calculated that if we use a traditional earth and stone bridge. This must be done with the construction of bridge piers, otherwise it is impossible to cross it, and only steel can be used to support the railway. Because steel is the lightest."

Ge Tiangong didn't say it too clearly. Steel is the lightest in the case of ensuring structural strength. Because the steel is the lightest, you can skip the middle pier and fly straight over.

There's something counter-intuitive about that.

Ge Tiangong said it for a while before these people understood this truth.

He Xi said, "Is there any problem?"

When He Xi was talking about steel bridges in Ge Tiangong, he was also thinking about steel processing technology in his mind. He thought about it, and it seemed that the current Zunhua Iron and Steel Plant was capable of casting large components. Of course, there is no way to compare this scale with the scale of later generations.

However, it also shows that it is technically feasible to build a steel bridge.

Of course, it is technically feasible, theoretically feasible, and in the end, there are not too many things that are not good.

He Xi is not a front-line worker in the end, and Ge Tiangong himself has to say.

Ge Tiangong worked in two iron works. Many people in these two places are Ge Tiangong's apprentices, he knows the iron-smelting technology very well, and he also knows the feasibility of this thing, and even Ge Tiangong's connections are all over the industrial system, and it is because of this that he dares to propose such an initiative.

Ge Tiangong said, "My lord, there is no problem with the various techniques. But there is one problem, that is, how to build this bridge, we don't have a specific charter, and we ask for your guidance."

This is a matter of course for Ge Tiangong. He is He Xi's disciple, but now he is above the temple, calling him an adult. If

Privately, of course, it is called the teacher. The disciple asked the teacher for guidance. It is also a matter of course.

It's just that it's a dilemma.

The things in He Xi's stomach have long been emptied.
