"Why is there no more? Then what is this iron cage used for?"
"Buried on the roadbed."
"Subgrade? Fill it with stones? It might be a little more stable, but how do you put the sleepers? Do they go through the frame?"
"With this, we don't need sleepers."
"How do you connect the track to the roadbed? You can't nail the track directly to the ground? We haven't used stone before. It's quite strong. Can we just use deformation nails to screw it in?"
Case and Goola asked questions one after another. After they finished asking the questions, they looked at each other, as if they could see their own confusion on each other's faces.
"Ah, this is a bit troublesome. How should I explain it? Now there is no way to directly build a section of roadbed for this thing to show you. Where will this thing fall? The platform under the steel cage is a trap door, which can be opened when in use.
, if this thing falls, it will fall directly to the ground, and then the steel cage will be connected..."
Polu raised his hand and gestured a few times, as if he wanted to start, but in the end he swallowed his words. He looked a little troubled, as if he didn't know where to start to make it easier for the two of them to understand.
"That's right! My butt... there's a flow chart!"
He looked around, and after a long circle, he found one of the managers of the Precision Institute who was watching from the crowd - he was introverted. Recently, he always hid in the Precision Institute and did not go out, so he had no sense of existence. He was very
Candice, who was content to be a drawing manager, waved her hand: "Candice, do you still have that sketch of mine? Oh, bring it over for me, thank you."
Bolu took the drawing, spread it out on a random table, and explained it to the two people who gathered around him.
"This thing is useless just talking about the cage. It is only a very small link. I have to explain the whole system to you so that you can understand it. You all understand the track, roadbed, sleepers, and ballast, right? Although ballast is cheap,
It is easy to use and can absorb a lot of energy, but there is a very annoying problem. When heavy-duty trains pass by, the ballast will wear out."
"Ah? Can such a hard stone still wear away?"
Polu glanced at Keith who exclaimed: "Of course it will be worn. If the stones don't get stuck and rub against each other, how can the sleepers stay on the roadbed? And the heavier the train, the faster it will break. If it takes a long time,
, it may shift when the train passes by, so it needs to be replaced after a certain level of use. Maintenance requires a lot of work.
And the most important thing is the question raised by Geola: We can't get so many high-quality stones, and we have to replace and maintain them, which will be exhausting. So I thought of a way, we don't use terrain
Did the transformation machine create a self-supporting vault of many stones? So I made a few more templates, or first pulled up the roadbed. Since the ballast was not enough, we directly turned the entire roadbed into stone with a terrain transformation machine, and finally turned them
Strengthen it and turn it into a whole track bed!"
To a certain extent, magic can do something that industry cannot - turn soil directly into stone!
No need for cement, no need for calcination, just one step to the stomach, mud and stone will transform into each other!
Judging from the results of the self-supporting vault, it is ideal to directly use stone to transform stone. It is equivalent to dissolving the stone first like a metal material and then pouring it together.
It is more difficult to convert mud into stone through experiments, and a large amount of impurities need to be discharged. Polu guessed that it was organic matter mixed in the soil, but there is no way to verify it.
And hardened pavement has an advantage that concrete pouring simply cannot achieve - it requires no hardening time!
Finished product!
Of course, the base material used for hardening determines the strength of the road surface. If it is just ordinary soil, the road surface reinforced in the experiment will probably have a texture similar to that of soil and cement. It cannot be used directly, and it will definitely be crushed by the train.
And if the soil is screened and even burned to remove as much organic matter as possible, the hardened soil can even be compared with low-grade Portland cement!
If you add some serious stones, iron ore and blast furnace slag into it, and add an elbow steel cage, it would be even better. The final effect is quite similar to concrete!
After observing the process of the mining machine destroying several entire experimental roadbeds, Polu was quite confident in his experimental results!
After digesting it for a while, Geola asked the question again: "Although the stone is hard, it has no toughness. If the force on the nail opening is too great, it will be crushed. The nail will be easily pulled out when the train passes by.
Is it dangerous? And the entire roadbed has been strengthened as a whole. Will the heavy-haul trains be shaken very badly?"
Bolu glanced at him in surprise: "Geora, have you ever built a road?"
"It has been repaired. In the past, we had to do everything by ourselves in Hongshan. Building houses and building roads. We don't like the quagmire created by the ore trucks rolling back and forth. The stone roads were paved a long time ago, but, really,
It's too dangerous.
If there is a little water on the stone pavement, mixed with some mud, the carriage can often slip sideways, and this is the problem with the stone pavement: it is not smooth enough, and it is extremely hard, and the wheels jump really hard when the wheels are pressed on it. The coachmen are very dissatisfied, and they complain about their foreheads.
The baby was in pain. In the end, I had to break them all into pieces. The small pieces were much stronger than the whole one.
So now that you’re saying, young manager, that the railway’s roadbed will be integrated, I’m a little worried.”
"Don't worry, our roadbed is guaranteed to be regular and smooth. Well... even if it's not smooth, the erected rails will automatically smooth out the unevenness of the road surface. At least it saves us the work of digging out stones and paving them all over the world."
Thinking of this, Geola reluctantly nodded, planning to wait until a section was built to see the effect.
"Then let me continue. On the roadbed pulled out by the terrain transformation machine, bury this frame first."
Polu clicked on the flow chart, straightened up and shouted behind him: "Smith, twist a pair of the track base with the base plate over to me!"
When Smith ran over twisting the base, Polu pointed to the base that looked like a steamed bun and said, "That's it. They are the part that directly fixes the track."
As he spoke, he turned it over again and again, revealing a steel plate on the bottom.
"This thing is called the bottom plate. From here, it is pulled to the top through these two long bolts. Then the bottom plate is together with the base, stuck in the cage, and finally hardened together."
"Then what if it gets crooked?"
Polu glanced at Case and felt a little tired of answering, but he still had to continue.
"Measure it properly when installing it and don't let it crooked! If it is really crooked, install the gasket not so powerfully. If it is completely crooked, there is nothing you can do. Just tear it off and start over."
"The last step is to install the rails. The rails sit on this base. Don't they have long screws sticking out? They are pressed on the base by the chuck. When our steel plate production increases, we won't need to harden this separately.
The base is made of pre-embedded steel, which is much easier to adjust.”
Hearing this, Case looked at Smith, who was standing next to him with a grimace on his face, and showed a subtle smile: "Young manager, it's easy for you to say. How long will it take Smith to build these tens of thousands of screws of this length?"
go?"
Polu also showed a subtle smile: "That's not necessarily the case. These tens of thousands of pieces are all the same size. Isn't this just a standard part? We always have something to think of."
