Comprehensive Martial Arts: Start Making Peacock Feathers

Chapter 73: Rubber, wagons, and cement

This is the specific process. After healing, Xie Yanke was arranged in the Phoenix Villa and temporarily became the bodyguard of the villa.

After listening to the explanation, Li Luoyun finally felt relieved: "It's good, with Xie senior here, the security of the villa will finally not have to worry about it.

Qiu Fengtong looked at the time: "it's almost time, we should leave.

"Yes, let's go."

Li Luoyun shouted, and the convoy set off slowly.

From Funiu Mountain to Bianliang, there are hundreds of miles in the middle. This distance is not very close. Fortunately, all the roads are official roads, and the speed is not slow.

It's just that Qiu Fengtong is very uncomfortable. Although the speed of travel is okay, it is mainly too bumpy. After all, in this era, even the official road is actually just a dirt road. At most, a little sand and gravel are sprinkled on it.

But on such a road, as long as it rains a few times, the sand and gravel will be stepped into the mud, and the places where the road should be potholes are still potholes, and the bumps are still bumps.

And just right now, it is the end of summer and the beginning of autumn. The sky is falling with autumn rain. Although it is not big, the ground is also wet and becomes muddy. The autumn rain falls on the body and it is even colder to the bone, so that Qiu Fengtong is a little bit cold. Unable to bear it, he hid in the carriage.

"Hey, my God, it's almost here. It looks like we'll have to get the rubber wagon and cement out."

After walking for a full ten days, it was finally time to arrive at Bianliang. Qiu Fengtong felt that he was almost completely out of his ownpi stock, and he was extremely unhappy.

It is no wonder that when the ancients went out for a long distance, it was like parting from life and death. Not only was it difficult to communicate, but the main thing was the road, whether it was riding a horse or a car, the wind and rain all the way down, bumps and bumps, and the life was lost first. If you get sick again and again, you are basically not far from death.

"Rubber wagon and cement? What's that.々?"

Xiaomeng opened her eyes and asked curiously.

Speaking of which, Qiu Fengtong had to admire his own wife. In such a swaying carriage, he was able to meditate calmly.

At the beginning, Qiu Fengtong wanted to follow suit, but it was obvious that his state of mind, Cultivation Base, was not at home, and he couldn't calm down. Down, completely unable to calm down.

"Rubber is the rubber produced by rubber trees. After special treatment, it has strong elasticity and ductility. It can be made into wheels and reduce bumps. But I mean, rubber trees are produced overseas, and Daming should not have them. Don't thought.

Qiu Fengtong casually explained that even if rubber is not made into a pneumatic tire, even if it is made into a solid tire, it can greatly reduce the bump length of the wheel... At least, it is much stronger than a wooden wheel.

It is a pity that the origin of rubber is Nanyang, and he has no way to go to sea for the time being. I am afraid that he will not be able to use rubber wheels in a short time.

But this is not a big problem, there are no tires to use other methods to avoid shocks, and when he comes back, he designs a shock absorber installed on the carriage, which can also reduce most of the bumps.

"As for a four-wheeled carriage, it is a four-wheeled carriage. Although many people think that a four-wheeled carriage cannot be steered, in fact, as long as the front two wheels are turned into movable wheels, and a steering gear is added to control, a four-wheeled carriage can also be controlled. The steering will not only be more stable, but also the carrying capacity will be greatly improved.35

You must know that a two-wheeled carriage cannot maintain an absolute balance, not only is it inefficient to carry goods, but also a considerable part of its weight is placed on the animal. bear part of the weight of the cargo.

The four-wheeled carriage is different, because it has four wheels, which can carry all the weight of the goods, and can maintain its balance.

This also means that even if it is the same horse, when pulling a two-wheeled carriage, it is already the limit to pull five hundred kilograms, but if it is a four-wheeled carriage, it may easily be able to pull eight hundred kilograms. Kilograms of things, this efficiency is completely different.

"What about cement?

Knowing the rubber and the four-wheeled carriage, Xiaomeng asked about the cement again.

This is also her strange place, shouldn't it be more difficult to walk on the road with water and mud?

"The cement here, not the kind of cement you think, is the name of a material.

Qiu Fengtong saw her doubts and explained with a smile: "The material is a kind of lime, mixed with various other messy things in a specific proportion, sintered at high temperature, and then processed through a series of processes. After that, a powder material cabinet is finally formed.

The reason why it is called cement is because the color of this thing is very similar to soil, and water needs to be added when using it, so it is named cement.

Cement is placed in a mold after adding sand and water, and when it dries, it becomes very hard, not inferior to stone, and will not deteriorate for a hundred years.

More importantly, the cost of this thing is very low, although it has not been cost-effective, but no matter how expensive it is, the cost of one kilogram of cement can never exceed five cents of silver (mainly because the price of fuel is too expensive, and coal in the Ming Dynasty is too expensive. 1.3 yuan per 100 catties, this price refers to the "Instructions for the Factory and Warehouse of the Ministry of Industry"), and the larger the output, the lower the cost. If the performance burns 100,000 catties at a time, the cost per 1,000 catties will be reduced to about one dollar... A thousand catties of cement can at least pave a ten-foot road. "

In fact (Qian Zhao), this is already more than Qiu Fengtong. According to the c25 specification, the concrete weight is 2.4 tons, the required cement weight is 305 kilograms, and it takes about 250 to 260 cubic meters to lay one kilometer.

Calculated at 250 cubic meters, the cement consumption of one kilometer of land is 152,500 kilograms, the demand per meter is 152.5 kilograms, and the one-foot-three meters requires 457.5 kilograms of cement. One kilogram of cement is enough to lay two feet of road, and there is still surplus .

And you must know that Qiu Fengtong was laid here according to the specifications of later generations. There are too many vehicles passing by in later generations, so the pavement has to be thickened, otherwise it will be crushed within two years.

But in ancient times, there were no such concerns. Not only were there fewer vehicles in ancient times, but also the load capacity was lighter, and the width was not so high. Therefore, even if the thickness was reduced by half, such a road would be enough for a long time.
