Tobe Shangshu raised his feet and walked forward.

This area is very flood-tolerant in the rainy season in spring and summer, and the water conservancy plan proposed by the old man of the Ministry of Industry is really expensive!

The money is not in his hands, and he doesn't think about how to save it!

The two walked a few steps, and Foreman Fu saw that the warmth was coming, and reminded the two stone movers, "Be careful, don't hit your feet!" Then he walked to the two of them: "Lord Fang, Lord Hui'an." ”

Hubu Shangshu stepped on a few bluestone slabs that had just been paved, very steady, and he said with a smile: "Foreman Fu, your road is paved just right, smooth and smooth, and there is no stumbling at all!" This bluestone slab is so good! How much silver is a piece of silver for such a good bluestone slab? ”

Foreman Fu smiled: "Master Hui, this is the smoothest bluestone slab, the upper and lower sides are flat, and it costs fifty yuan a piece." ”

The Lord of Hui'an requires the best materials, so it is more expensive.

There are also very cheap ones, such as 20 yuan a piece, 10 yuan a piece, those that are not so smooth, square, and shop to spend time and effort!

“........”

Fifty pieces of money?

The county lord of Hui'an is really rich!

Tobe Shangshu looked at the long roadbed dug up, and the bottom of the roadbed was also paved with a layer of mud and sand, and it was tamped and flattened with huge rolling stones as a base. Then pave the bluestone slabs!

In such a short road, at least tens of thousands of bluestone slabs were built, and then with labor, silver from other materials, there were no three or four thousand taels, absolutely not!

Now the roads in the city, except for the roads in the area of the powerful, are not paved like this!

It's too much money.

Hubu Shangshu thought that it was impossible for the county lord of Hui'an to repair all the roads in the outer city, even if he used the cheapest bluestone slab, ten yuan a piece, so many roads, it would be a lot of money to build!

And the cheapest bluestone slabs are uneven, stumbling, not easy to shop, and not easy to use in the city, that is to say, you have to use at least a medium thirty yuan.....

Tobe Shangshu felt a little dizzy when he thought about it.

"It's not easy to polish such a bluestone slab, right?" Warmth asked.

Fifty wen a piece is considered cheap.

So thick, so big!

Foreman Fu nodded: "It's not easy, otherwise we can pave bluestone roads everywhere in Nalan Country, why are there bluestone roads only in the city, it's because of trouble!" ”

"In fact, the bluestone slab is bulky, and it is not easy to polish it out, which is time-consuming and laborious and costly, is there any way to change the method of building the road, and not use the bluestone slab to build the road?" Warmth thinks of the modern road.

I also thought of the famous Qin Straight Road, which seems to have been built with mirage.

In this era, the road pressure is not as great as that of modern times, after all, there are no heavy trucks, just horse-drawn carriages, and the heaviest horse-drawn carriage is only a few hundred pounds!

It is estimated that it should still be bearable.

I don't know if it's warm, but I'll know if I try it!

Isn't the reason why human beings have modern civilization and the development of science and technology because they are constantly exploring and trying?

The left eye of the Tobe Shangshu jumped, and the left eye jumped rich!

Does this mean that the county lord of Hui'an has a better way to build roads?

"Is there any good way for Lord Hui'an?" Foreman Fu knows warmth and knows a lot to hear.

The road and the drainage system were designed in a very reasonable way, even more reasonable than she thought.

No wonder the young master and the foreman of Ningyuan County praised her endlessly.

"I actually don't have any good way, that is, I have to use stone anyway, such a large bluestone slab is troublesome to polish, I don't know if it is okay to use crushed stone mixed with yellow clay lime mortar instead of bluestone slabs to pave on it, so that this road should be relatively smooth!" Warmth began to guide Foreman Fu to change the way the road was built.

Don't underestimate the wisdom of the ancients, the Great Wall is standing tall for no reason.

But when it comes to roads, the roads of ancient Rome are world-famous.

As the saying goes, all roads lead to Rome!

The roads of ancient Rome were more than 400,000 kilometers long, enough to circle the earth ten times.

But the Roman roads were also paved with stones, and the foundations were very well laid, with four layers of foundations.

It's not for nothing that it's world-famous.

But it doesn't have to be here, it's more time-consuming and labor-intensive.

Foreman Fu shook his head: "No, it is estimated that there is no problem for people to go, but I am afraid that the carriage will be easily crushed when it goes, especially on a horse full of goods, and the weight of hundreds of catties will be pressed down." Day after day, year after year, it is estimated that it will be crushed in a year and a half! How can there be a heavy bluestone slab that is practical, and it can be used for a hundred years! ”

Tobe Shangshu nodded.

Look at the stone road in the city, it has been more than 100 years since the founding of the People's Republic of China, and it is still used well!

Thinking about it this way, a few thousand taels of a road is actually quite cost-effective.

After more than 100 years, I don't need a penny every day!

Wen Wen smiled: "The road paved with bluestone slabs can indeed be used for a hundred years and is not bad, this is paved in the city, I also think it is good, practical and trouble-free!" But doesn't the official road have to be paved?

There is a saying that the road is easy to go, but it brings a lot of convenience and saves a lot of time to the merchants.

If the journey can be saved by half, there will be many fresh goods in the north and south that can be exchanged! At that time, will the living standards of the people in the two places be raised by a higher level? ”

At this time, the emperor walked back with a few officials.

The group stood on the side and listened to the conversation between the three of them.

Hubu Shangshu: "The official road paves the way? No, even if the yellow mud lime mortar is mixed with gravel, the hardness should not be enough! It will break down quickly! Isn't this a waste of money and energy? ”

Foreman Fu nodded: "These are still feasible for sticking the gaps in the stones, after all, there are stones that bear almost all the weight. ”

Warmth continued: "What if you add some iron branches to make a bracket and mix it with gravel to carry most of the weight?" ”

When the Ministry of Industry Shangshu heard this, his heart was full of disdain, and he almost laughed out loud, but because Nalan Jinnian was by his side, he didn't dare, he just said: "Lord Hui'an said to use iron? Lord Hui'an, do you know how valuable iron is? Do you know what the iron of Nalan is used for? ”

Can iron be used indiscriminately?

Paving the road with iron?

Why didn't she say that she would use gold to pave the way?!

It's just that I don't know how to pretend to understand, nonsense!

Hearing what Nuan Wen said just now, Shangshu of the Ministry of Industry felt more and more that it was actually difficult for the county lord of Hui'an to be famous!

Her credits, maybe they were really deliberately given to her by King Jin in order to improve her status!

Now that she has merit in agriculture and military service, does she still want to take credit in paving roads and bridges?

It's your own domain!

His credit must not be robbed by others!

King Jin can't do it!

Foreman Fu: "Lord Hui'an, iron is very expensive, and it is difficult to refine, it is better to use bluestone slabs than iron!" ”
