Kang Hui listened to Su Baiyi's words, and his face suddenly turned pale.

He had already guessed before, and when he saw the train, he understood even more that it must be "boiling water with fire, steaming water into gas" and then relying on the power of the atmosphere to push the train to run.

Since the power of fire and water can propel a train on the rails, it should also be possible to propel a ship on the sea.

He thought about it a little deeper: if this big ship was driven by the power of water and fire, and could do without sails, and without sails, it could walk on the ground regardless of whether it was good or bad, then how much more would the speed of navigation increase?

If so, how big should the ship be?

That own shipyard......

I can't think about it, the more I think about it, the more scared I become.

Raising his head again and seeing Su Baiyi's calm gaze, he suddenly understood why Su Baiyi had patiently told him the story of the Mu family's weaving before. Knowing now, he understands: people are really not oppressing people with power, but telling him, you and I cooperate, cooperation can also benefit both, if you don't cooperate, once I produce a big ship, you can die.

"Promise, since Lord Su cultivates like this, if the villain doesn't know the current affairs, he will inevitably have no eyes." Kang Hui smiled, put the tea that had been spilled in his hand on the table, and arched his hand: "This kindness, Heluokang's family will never forget!" ”

"Okay, with Mr. Kang's help, it will definitely be smooth sailing!" Su Baiyi held his hand, and he was also very happy in his heart.

The matter of railway fundraising was solved, and the matter of shipbuilding cooperation was also solved.

The rest is to wait at home to collect the money.

Su Baiyi rested for a while in the warm pavilion next to the study, and came out again at noon, and the people in the East Garden had basically finished.

had a festive meal with the four beauties chattering for a while, and said to Su Yanzuo, "How many steamed buns can I buy for 18 million?" The right sentence "How many houses can you buy with 18 million silver?" During the questioning, Su Baiyi fled weakly, and his heart was full of cows.

Enough money!

The silver is there!

The rails have been reproduced!

Everything is ready, which means that the construction of the railway can begin.

After eating at noon, there was no rest, and the students led by Li Suo and Chu Lun came to the large conference room of the headquarters. Su Baiyi bought a full set of Longhai Railway drawings from the system and put them on the table, watching little by little.

As far as the entire Longhai Railway is concerned, if you follow the original trajectory built at the end of the Qing Dynasty, it is about 1,000 and 50 kilometers.

Su Baiyi thought about it, and this thousand and fifty kilometers can be roughly divided into three sections: a section from Haizhou to Guide Mansion; the second section is returned to Defu to Luoyang; Three sections of Luoyang to Xi'an.

Among them, the length from Haizhou to Guide is about 350 kilometers; The section from Guide to Luoyang is also about 350 kilometers, and the section from Luoyang to Xi'an is a little less, about 350 kilometers.

Su Baiyi flipped through the first drawing and looked at it carefully.

A section from Haizhou to Guide Province is basically a plain, without any mountains in between, only occasionally encountering some small rivers, the width of which is about 100 meters.

In other words, there are only roadbeds and bridges, no tunnels in one section.

Needless to say, after the roadbed is leveled as much as possible, the railroad is paved with stones on the flat ground, and the roadbed is filled higher when it is really encountered on a country road, leaving enough space for the locals to build an underground passage to pass through the car. The second is the bridge.

Repairing the bridge is a little more complicated.

But now with steel and concrete, it is much easier to build bridges on small rivers, and the common method is to block half of the river to repair the bridge, and after this half is repaired, let go of the water flow and block the other half, and then the whole bridge is repaired.

As long as you don't touch the Yangtze River, the Yellow River, and the Huai River, which are more than a few hundred meters wide, it is the fastest way to build bridges with this half-sparse and half-blocked method.

The second section is from Defu to Luoyang, most of this section is plain, only after Zheng County (Zhengzhou) from Gongxian to Luoyang in this section, because of the remaining veins of Songshan Mountain, there are some small mountain bags, and the railway is not so straight when it is built.

Su Baiyi found that the Longhai railway line in the late Qing Dynasty and the early Republic of China was not at all like modern road construction. This Longhai line follows one principle when choosing a line: avoidance.

Avoid mountains when you see them, and try to avoid water when you see them.

Those who can not build bridges will resolutely not build bridges, and those who can not open mountains and tunnels will resolutely not build tunnels. So this section of the Longhai Railway from Gongxian to Luoyang is like a winding mountain road, walking around the mountain in a zigzag way.

But it doesn't matter much.

After all, the railway built by Su Baiyi will not run too fast, at most forty kilometers to the sky, and the alignment of the railway is a little uneven, and it doesn't hurt.

The alignment of the second section of the railway winds around, but it is not yet possible to get out of the way of all the small hills, and there are two tunnels on the railway from Gongxian to Luoyang. But it's not very long, around three hundred meters.

Su Baiyi sorted out the plan drawings of the second section of the railway, and then put them away. I picked up the plan location drawings of the three sections of the railway and watched them.

The three volumes are a little sad.

Starting from Luoyang to the west, after crossing Sanmenxia, the junction of the two provinces of Henan and Shaanxi is the remaining vein of Taihang Mountain. The mountains here are relatively gentle, and the mountains are not very high, but there are many of them.

So the railway planned at the end of the Qing Dynasty and the beginning of the Republic of China began its serpentine FA again.

To be honest, when Su Baiyi first saw it, his heart was full of contempt: This is also called a railway? How much more labor does it take to repair it, and how many more detours does it take?

This kind of railway is destined to never be able to speed up to more than 80 kilometers per hour in a lifetime!

Looking, laughing, laughing, despising!

The people at the end of the Qing Dynasty were still too weak!

Hey?

Wrong!

Su Baiyi's face instantly became suspicious.

The Longhai railway line, starting from Luoyang, along the north bank of Luoshui, all the way from Luoyang to the west winding extension, from Luoyang to Xin'an, from Xin'an Daoyima, from Yima to Guanyingtang Town, and then into Sanmenxia.

That's not right!

What about Luoshui?

When did Luoshui pass?

This railway runs from Zhengxian to Sanmenxia, it is impossible not to pass Luoshui?

But if I pass Luoshui, why don't I have any impression?

Because Luoshui is too wide, not to mention the widest, the average place is four or five hundred meters wide, even if it is a little narrower, it should be more than three hundred meters.

At the end of the Qing Dynasty, it was impossible to build such a big bridge!

But if you don't cross Luoshui, how can you get to Luoyang from Zheng County?

He rummaged through three large stacks of flat drawings, but he couldn't find the answer.

Su Baiyi's face was solemn and he began to look backwards, turning forward from Luoyang, one by one, and I don't know how many volumes I turned, and I couldn't help but breathe a sigh of relief when I saw a small bridge across the river on the west side of Gongxian County.

Found it, this is Luoshui!

Longhai railway from Zhengzhou to Luoyang, originally directly from the south of Gongxian to the west can go directly to Luoyang, not only the line is beautiful and will save a lot of time, but why do you want to go around Gongxian a little north?

I see!

Only in this place in Gongxian can we perfectly cross Luoshui and then make the whole railway transition to the north bank of Luoshui, otherwise it will inevitably cross a river hundreds of meters wide!

What a painstaking design.

Su Baiyi took a deep breath, and with a different state of mind, his eyes fell on the design line of the Longhai Railway again, this time he saw not contempt, not ridicule, but shock.

At the end of the Qing Dynasty, this old Longhai, in the era when there was no technology to build bridges and dig large tunnels, in the era when there was no aerial photography of all the terrain and relied on manpower to find, it relied on ingenious design, perfectly passed through Luoshui in the west of Gongxian County, and then circled and stretched to the west after passing Luoyang, Cijian Town, Xin'an County, Yima, Mianchi, Guanyin Hall, all the way through the mountains and streams, like a trail in the mountains and mountains, crawling all the way, he perfectly avoided Luoshui, and cautiously approached the Yellow River. Walking side by side with the mother river on the land of China, a line of life has been wound out from the vast Taihang remnants.

It may have taken many detours, and it may not meet the current design standards, but it surpasses the most impossible technical conditions in the simplest and most ideal way, and goes straight to the east and west, connecting Henan and Shaanxi.

Out of Henan, it is still difficult to crawl forward, crossing Tongguan, crossing Huayin, approaching Weinan, and finally closing the line in Xi'an.

Su Baiyi's eyes changed, what he saw was not naïve and ridiculous, but the respectable spirit of the master.

Because it is this site, it is this line, until the new century many years later, the Zhengxi high-speed railway is still in use.

Su Baiyi took a deep breath and silently paid tribute to the master who designed this road at that time. Whether you are French, Belgian, or Chinese?

"How lucky!" Su Baiyi sighed: "If it weren't for this old Longhai, if you want to pass through the two famous mountains of Taihang and Songshan between the Yellow River and Luoshui, I really don't know how many bridges to build and how many tunnels to open!" ”

Su Baiyi silently closed the three-section floor plan, and then sorted out the volumes one by one and put them together, falling into deep thought.

Even with such clever design methods, even after so many detours, Lao Longhai still can't avoid all the mountain bags, and the tunnel still has to be opened.

In total, about eight tunnels need to be excavated.

This was unexpected.

But the good news is that they are all extremely short tunnels, and the longest is only more than 300 meters.

"If it can be opened at the end of the Qing Dynasty, I don't believe that I can't open it!" Su Baiyi patted the table, full of confidence.

It's a big deal, it's just a two-year delay.

At this time, Chu Lun and Huang Heng came in from outside with more than thirty dark-faced students, and after saluting, they each stood around the conference table, looking at Su Baiyi with admiration and respect on their faces.

These students should be the most professional surveying engineers in the whole Yuyuan, not only the planning and construction of the Yuyuan before, including the later glass workshop, textile factory, blacksmith shop and steel workshop by the river, as well as the steel production workshop under construction, all of which are engaged in measurement and positioning.

But those are all petty fights.

The real measurement is still on the Longhai Railway.
