Liu Wenbing did not die in a catastrophe, and he called it lucky in his heart. However, after coming back to life from the brink of death, Liu Wenbing has undergone some changes. Take the opinion of "retro rails" as an example, the front and back are like two people.

In fact, after Liu Wenbing experienced two life and death tests before and after, he faintly had the consciousness of changing his life against the sky in his heart. He himself definitely didn't realize it, but his confidence naturally improved, and Liu Wenbing, whose personality was by no means strong, also had a strong man thinking, and the pride of "man will win the day" began to rise in his subconscious, Liu Wenbing seemed to feel that many things in the world could actually be subverted.

"Retro rails" are a bit weird, and even a bit against the historical trend, at least not scientific! Prior to this, Liu Wenbing simply thought that such a choice was completely short-sighted. But now it's good, Liu Wenbing keeps saying that "the right one is the best", claiming that at the moment, "retro rail" can be called the most suitable solution for the carat road, and there is no one.

Liu Wenbing completely fell into the retro school of rails, Tang Kai was very excited, and Han Huanzhang was very excited. And Ma Fen only has a wry smile, damn! Liu Wenbing fell ill, and his brain was simply funny! Wang Feng's opposition was not very fierce, but on this issue, he has now been further reduced to the role of playing soy sauce.

But no matter what, whether you oppose it or approve it, the "retro rail" test project personally grasped by Han Huanzhang has been paved, which is a 500-meter circular track that fully considers the turning radius. The track is made of concrete, and the whole track is high in the middle and low on both sides, and I don't know what the design effect is, but now the cement is hardening, and it will be tested in five or six days.

In terms of creativity, it came from Tang Kai, but the host was Han Huanzhang, and Han Huanzhang did not add his own private work in the process. Of course, the specific implementation is still Guo Huazhang, in terms of execution, except for Ma Fen, there is really no one who can compare to Guo Huazhang, and even the big step is ashamed.

But Buda has no interest in competing with Guo Huazhang at all, he is addicted to arson during this time!

Arson in the rainforest is also quite technical, the climate here is humid, and humanity is "**", not bad! There is dry firewood, the fire can be burned vigorously immediately, but unfortunately although the plants here grow luxuriantly, but it is not very suitable for firewood, it is not completely impossible to burn, or it is more troublesome to burn, and there is a lot of smoke, a small piece of mountain forest fire, a radius of more than ten miles are shrouded in smoke, the whole sky is black and black, and you can't see people clearly from a few meters away.

"Dude, this posture is so good compared to the sandstorm in Beijing. It is said that murder and arson are the profession of this guy, but I can't imagine that professional arsonists don't pay attention to technical content at all. Tang Kai complained.

"Hehe, I look at this visual effect is very good, the poem says, 'The desert is lonely', the visual effect is amazing!" Rainforest black smoky', haha, which is not smoked to the crimson eyes, fuck, the visual effect is really fucking spectacular, but the effect of smoking people is also fucking terrible. ”

Hearing Han Huanzhang's bad artistic tone, Ma Fen was quite dissatisfied:

"Shit! And the visuals! I can see everything the fuck! Visual fart! How to say that paragraph, the farthest distance in the world is holding your hand, but you can't see your face. This is talking about the smog of the later generations, if you want me to say, the haze is a fart! Compared to this, it's just weak. ”

"Ma Dao, I think it's better to smoke this smoke, choking people and smoking their eyes, that's nothing, if you want to eradicate malaria, you have to smoke it like this, and smoke all the pests and insects, especially the hateful mosquitoes, which is worthy of my Lao Liu." Although Liu Wenbing escaped death, he really had lingering fears about the malaria parasite that spread malaria, knowing that it was impossible to burn all the mosquitoes by a fire.

The smoke is getting thicker and thicker. The arson was seven or eight kilometers apart, but the smoke was billowing in, and it looked like it was going to spread to the sea soon.

The four of them ran all the way out of the smoke, and they could finally see each other's faces clearly, the faces of the three were full of smoke and dust, and their eyes were red like rabbits, and their images were particularly funny, Tang Kai laughed first, and then the four of them laughed together.

The fire over there has gone through a period of thick smoke brewing, and now it has gradually become a fierce fire, and the smoke is no longer as fierce as Fang Cai, and the arson of this mountain forest has now turned into the stage of fire. But the tropical weather changes as it goes, and suddenly without warning it crackles and rains, and the sky is obscured by thick smoke, and it is long time impossible to distinguish whether it is sunny or cloudy, let alone dark clouds.

The rain became heavier and heavier, and the sky became like night in a haze formed by smoke and rain fog and steam.

Soon after, the fire was extinguished by a heavy rain. As soon as the sea breeze blew, the smoke slowly dissipated, and after a while, only wisps of smoke remained in the distance, and it was impossible to distinguish whether it was smoke or steam.

Felling and arson, arson and felling, this is the work of the group led by Buda, anyway, the time is not so urgent, the heavy rain extinguishes the forest fire, and it will be good to burn it again. In the environment of tropical rainforests, there is no dry season in the full sense of the word, and it is impossible to turn a fire into a prairie fire, only to burn it one by one. In two months, it is estimated that no matter how difficult it is, it will be able to burn a field that runs through the east and west coasts.

As soon as the heavy rain stopped, the smoke of the Kra Isthmus began to rage again, and the days passed little by little in the smoke.

On this day, Long Jiu arrived.

"Not bad! Burned half the distance, right? "Ma Fen was the initiator of the arson, and Long Jiu looked at it in the faint smoke, and a burned field stretched in6, which did seem to make people feel very accomplished. Long Jiu still wants to admire Ma Fen.

"Hehe, this is nothing, there are still more than ten days, it is estimated that the east and west will run through, arson has no technical content, it is not as popular as the 'Greek track' engaged in by Dr. Tang and Han artists, Long Jiu, I am now a minority, you won't approve of them coming nonsense, right?"

"What is 'Greek Rail'?"

Long Jiu was a little confused.

As a result, Long Jiu was led to the ring rail test site.

At the beginning, the five traversers who went west were all accompanied by them, and it was Guo Huazhang who commanded the test drive.

A central bulge that Ryukyus saw on both sides of a circular track that was level with the ground.

Walking on the edge of the track, Tang Kai pointed to the track and introduced:

"You see, the two rails are poured separately, the shape of the rail is L-shaped, because it is a test rail, the thickness is only 15 centimeters, the width is 28 centimeters, the width of the flat part is 2o centimeters, the height of the rail is 8 centimeters, the width of the rail is also 8 centimeters, and the wheels of the carriage are limited by the convex rails of 8 centimeters, and they can only rotate on this 2o centimeter flat road."

Long Jiu looked at it, isn't this just two L-section cement lumps in the style of elephant angle steel! Relative to each other, it is a section of rail, the rest of the rail is dirt, the middle is all filled with mud, the height is just flush with the eight centimeters high rail, from the cross-section, it is a wide and low boss higher than the datum plane, eight cm higher than the datum plane. The main element of the boss is two L-shaped concrete elements, filled with earth in the middle, and it's as simple as that. There is a reason why the soil should be filled to the same height - this design has the advantage of not creating water in the middle.

The rails are partially made of concrete, and the rest is filled with dirt, well, it saves cement.

"The one-meter L-shaped track is O.O5 cubic concrete on one side, and the one-meter track O.1 cubic concrete is still very economical." Tang Kai studied business administration, and thought that the "retro track" he created was economically cost-effective.

"Oh, I wonder how it goes?"

has tried it before, and Tang Kai is of course full of confidence. I saw Tang Kai gesticulating, and the driver over there understood, and immediately flicked the horsewhip, and the carriage that had been waiting on the track for a long time began to gallop.

This is a horse-drawn carriage with traditional wooden wheels, and the four hooves of the pulled horse fly over the raised road in the middle, and the two wheels of the carriage are embedded in the rails and rotate, which does not look slow.

"Let's go, get in the car and sit down." Han Huanzhang came over and warmly invited Long Jiu to get in the car and try it out.

The carriage stopped after two laps, and Long Jiu was full of interest, so he got on the car with Han Huanzhang for a test ride.

This is a traditional carriage with almost no shock absorption mechanism, and the bumpy feeling of the carriage is still obvious when it runs, and occasionally you will feel the left and right jumping, which should be caused by the turn or the wheel bumping against the side of the track. Despite this, Ryuhisa felt much better than riding in a carriage on a dirt road.

"How? It's okay! How many kilometers can you run? ”

"This track has to turn all the time, you can't run fast, 35 kilometers is the most, if you are on the official track, it should be easy to run 45 kilometers in an hour."

"Well, that's good! If this rail carriage is equipped with a shock absorber or something, I believe that the comfort can be even further. ”

In fact, this time Long Jiu came to transport grain, grass and military supplies, because he received the news that the three people had malaria, so he specially came in person.

The reason why some military funds were sent this time was mainly to prevent the King of True Wax from sending troops to the Kra Isthmus, which is nominally also the territory of the True Wax, although it is not only equivalent to the situation of the Great Song Dynasty's "bondage" in terms of jurisdiction, and the small fights are just like the skirmishes of hundreds of dead and wounded people last time, it is estimated that the King of True Wax has no time to take care of it, but if there is really a big movement, the King of True Wax will inevitably send troops to come. In order to make the King of True Wax have no time to look west, Chen Liang has long been inciting the city to move westward, and it is estimated that the King of True Wax is already preparing for the attack of the city.

When I came here, I saw that the three guys who had malaria were now recovering. The arson of the Kra Isthmus has also been opened. It seems that after a big stick and a radish, the natives here have already taken shape.

Judging from this posture, there will be no real wax soldiers and horses for about a while.

It seems that the shape shì is good.

It's just that he didn't expect that other things had not been communicated well, and Long Jiu was first pulled into the whirlpool of rail transportation.

Funnily enough, Long Jiu searched for a memory in his mind, and said it to the other five traversers:

"You know what? Nanyang has an archaeological scene in the 21st century, which is claimed to be more valuable than the terracotta warriors. Hehe, it is said that because of this archaeological scene, experts claim that Qin Chi Road is actually a kind of rail transit that uses wood as a track, with sleepers underneath and wooden tracks on it, and it is said that the design of this wooden track is still very advanced. ”

"Brag!" Tang Kai naturally didn't believe it.

"This is true, there is a picture and a truth, I have seen it on the Internet. What do you think? The Qin Dynasty was able to use wood to make tracks, and it is said that the effect is very good, why don't we try to make tracks out of wood here? ”

This time, a new clue came out. Ma Fen was an orthodox advocate of modern roads and railways, and is now a typical minority. Wang Feng is a soy sauce maker. These two people have more and more clues about retro.

Of course, Long Jiu is also to say that Long Jiu is very good at being a man, first Long Jiu is not against rail transit, on the contrary, he is very supportive, in good conscience, this demonstration track gives Long Jiu a very good impression. Well, it is worthy of the people who came from later generations, and the demonstration project has done a good job.

However, it is clear that more money will be invested in the construction of the tracks. The proprietor who invested the money, one of course is the Crossing Group, which is mainly Mao Geng's final say, and the other is Huaxi Company, which is Chen Liang's final say. In addition, it would be better if we could raise some more funds to build roads.

The experience of later generations shows that if the report is well written, the strategy is written, the concept must be conceptual, and the demonstration project will be able to "run the money in", which is the only way to fool the state appropriation.

So, a copy was written to Maute as a carefully packaged plan for the improvement of the "Greek Rail". Long Jiu's statement is that what Maote has learned and mastered is all Western learning, and of course it will be a little louder to play the Greek signboard. Han Huanzhang strongly agrees with this, at least in his mind, Greek art is very sacred.

One was written to Chen Liang, and it was the "Qinchi Road Rail" improvement plan. This is in view of the fact that Chen Liang belongs to a typical Huanghan faction, so it is natural to play the signboard of "ancestor" to compare his appetite.

Unexpectedly, this led to a big debate, whether the Qin Dynasty had a "wooden rail galloping road"!
