Datang first village

Bai Erwa stared at the cement board for a while, then said slowly: "Your Highness said that this board can bear two thousand catties! It's already two thousand catties now, I don't know if adding iron ingots will damage it." Lose!"

After hesitating for a while, Bai Erwa motioned for someone to put another ten yuan, that is, one hundred catties.

As a result, after another 20 yuan went up, the slate remained the same, without any movement.

Will breaking this stone slab make His Royal Highness Qin Wang unhappy?This is a full [-]% weight beyond the limit His Highness said. Although there are still three hundred catties of iron ingots, Bai Erwa really hesitates.

Li Chun, who was standing aside, did not dare to speak.

After looking at the monitor for a while, Li Yuanxing saw the problem. The load-bearing was not tested in this way.According to Bai Erwa's order, more than [-]% of the weight is not borne by the board, but distributed to the pillars.This is testing the stone platforms on both sides, not the board.

What's more, neat and staggered placement will definitely disperse the pressure.

If you only add two thousand catties to the center of the stone slab, it will definitely be broken.

Thinking of this, Li Yuanxing picked up the walkie-talkie at hand: "Erba, approach Li Chun, let Li Chun hear my king's voice!"

Just the appearance of King Qin's voice is shocking enough.

Li Yuanxing said at this time: "Li Chun, I ask you. What is the difference between placing the two thousand catties of iron ingots in this way and all falling in the middle."

"Your Highness, it should be the principle of weighing rods!" Li Chun answered with his own knowledge after regaining consciousness.

People in Datang didn't know leverage yet, but they did know about weighing. The weighing at that time used the principle of leverage.

"Criminals dare to think that if they are all piled up in the middle, the stone slab may break!" Li Chun replied respectfully.

"Erba, break the stone slab. Let Li Chun look at the break and bring him to see the king!" Li Yuanxing cut off the walkie-talkie after finishing speaking.

walkie talkie!

This thing can be said to be a symbol of the special status of the Qinwangzhuang Guards, and there are only eleven in the entire Qinwangzhuang.Nine of them are in the hands of people with status in the guards, such as four gates, front, rear, left, and right, and there are five gates in total, including two gates at the main gate.The general on duty is responsible for holding it.

Then Bai Erwa, Lao Lang, and the generals on duty from the left and right battalions each have one.

There is one for the gatehouse of Li Yuanxing's study courtyard, Li Yuanxing has one in his hand, and another one that cannot be moved, which is similar to the function of a base station, is placed in Li Yuanxing's study, and an antenna is also erected in the backyard of Li Yuanxing's study.

There is another walkie-talkie on his waist, but it is much more majestic than a famous knife.

Even the palace doesn't have a mythical talking box, this thing is second only to Bai Erwa's rechargeable portable spotlight in the hearts of the guards.

The cement board finally broke, and even the steel bars were thinned and broken.

After removing those iron ingots, Li Chun looked at the break for as long as a cup of tea.He could already see that the slate should be made artificially, but he didn't know how it was made.The steel bars can increase the strength, and so can the bamboo bars.Especially the hollow part, which is coiled with bamboo, is even more wonderful.

After Li Chun left, the broken cement board was carried away.This cement board will be broken, and the steel bars inside will be taken out and returned to the furnace, which can be used to make other things.

"Your Highness!" Li Chun knelt down on the ground after entering the small reception room.

"Get up and talk, Qin Wangzhuang is not happy to kneel down. You have the talent of a first-class master craftsman, but you have not made the contribution of a first-class master craftsman. Sit down here, and I will chat with you!" Li Yuanxing signaled Yuanchun to give Pour yourself the tea.

But in front of Li Chun was a cup of goat milk.

"Drink a cup of goat's milk, your body is too weak. Take good care of yourself for a few days, this king needs you to do great things!"

Li Chun was sitting in the designated position, a beam of light shot out from behind him, Li Chun's heart was already a little numb, it is rumored that King Qin of the Tang Dynasty came down to earth from a star king, so it is not surprising that there are any miraculous things in King Qinzhuang.

The beam of light shone on the cloth, forming a picture.

A detailed drawing of Zhaozhou Bridge after it was disassembled, which is a masterpiece of bridge engineers of later generations.

"A very perfect bridge, one part more is more, one part less is less. Especially the two small arches can increase the strength of the bridge body and reduce the weight of the bridge body. About 28% of the stone materials can be saved and the Weight can increase the load-bearing capacity of the bridge. The arch is smaller than half a garden, and [-] small arches are connected to form a large arch. This bridge has three unique features!"

"Thank you, Your Highness, for your compliment." Li Chun stood up and saluted.

Li Yuanxing waved his hand to signal Li Chun to sit down: "The thing you saw just now is called a reinforced concrete prefabricated panel. It is made of steel bars, cement, sand and stone, and water."

The picture has changed again, and it is a structural drawing of a reinforced concrete prefabricated slab.

"Well, you can study it. But the king of cement can only give you [-] catties, at most [-] catties. And the steel bars are only [-] catties of fine steel, but the fine iron nails can give you [-] catties. However, this king The bridge I want you to build will only give you four months to complete, and the bridge will be flat, and the bridge will be five hundred steps long!"

Li Chun was surprised, but not surprised.

This is a challenge, a challenge for one's own bridge life. With such a bridge, there is no regret in death.

As if guessing what Li Chun was thinking, Li Yuanxing said again: "If you are satisfied with only a bridge of [-] steps, then you have disappointed me. What I want in the end is [-] steps, the Yellow River Bridge. If you want to have your name engraved on a stone after you die, I hope that the Yellow River Bridge will have your name on it!"

Li Chun got up, arranged his clothes very solemnly, and bowed.

Get up, straighten your clothes again, and give a long salute.Get dressed again and kneel down!

"Thousand-step stone bridge! I'll give you a reference, I imagine you can do better!" Li Yuanxing turned off the projector and put the two pictures on the table.One is the effect drawing of Lugou Bridge, and the other is the design exploded drawing.

Li Chun has seen this picture once, compared with the half-crazed him, and the calm him now.

Now that he had calmed down, he knew the value of this picture.

If it is said that there is no first-class master craftsman in the Tang Dynasty, then how would His Royal Highness King Qin evaluate these masterpieces.If it is said that Datang has a first-class master craftsman, then how to evaluate the masterpieces of His Royal Highness King Qin.

There are already a lot of rumors about Sun Shenxian in the market.

Sun Shenxian has always refused to accept the badge of a first-class doctor. The world thinks that Sun Shenxian is modest and polite.

There should be three rejections before getting the badge of a first-class doctor.

But at this time, Li Chun seemed to understand Sun Laodao's thoughts. In front of His Royal Highness King Qin, you are eligible to win the first-class badge, not because of your skill or ability, but because of what you have done.Only when it is done, can you wear the first-class craftsman badge with peace of mind.

When Li Chun resigned, Li Yuanxing said again: "Don't think highly of yourself, and don't look down on yourself. A good bridge can save people from taking many detours. It can make food and goods arrive faster. Its contribution is far greater than The meaning of a bridge itself is that medicine is the way, and craftsman is also the way!"

Li Chun held the blueprint high above his head, bowed and withdrew.

The bridge must not only pass people, but also not affect the ability of river transportation. This is really a test.

Li Chun went crazy again, this time it was a normal madness, he asked for twenty clerks for arithmetic, four servants for grinding ink and doing miscellaneous work, and he asked for a cartload of papers alone.

He wants to calculate, he needs to calculate in detail the magic of the Marco Polo Bridge.

Moreover, he also specially applied for four coils of a thousand-foot long rope and six carriages.

Li Chun wants to conduct an on-the-spot investigation.

Moreover, Li Chun wanted to test the cement himself, and Li Yuanxing agreed.

Du Ruhui came to see Li Yuanxing in person, and he came for Li Chun.

"Your Highness, do you think that the bridge builder is qualified to be a first-class master craftsman just because of a bridge?"

"Mr. Du, don't underestimate a bridge. Does Mr. Du know the actual benefits brought by a good bridge?" Li Yuanxing asked with a smile.

Du Ruhui pondered for a moment: "If, as His Highness said, a Yellow River Bridge appeared in Lanzhou, then the Tang army could travel three thousand miles west without any logistical pressure. The benefits of the Silk Road will increase by [-]%!"

"Bridge charging can recover the cost of the bridge in five years!"

Du Ruhui knew Li Yuanxing's irrelevant words, and he only thought Li Yuanxing was joking.

Li Yuanxing sighed softly: "Actually, the king wants more than one bridge. If Feng Lingdu had a bridge, what would happen?"

The map of Tang Dynasty flashed quickly in Du Ruhui's mind. The Yellow River runs from north to south.

Occasionally, when the water flow is calm, there are simple pontoons, but the water flow is calm for a few days a year.

If there is a bridge in Fenglingdu, the requirements are not too high, and there are three hundred horse-drawn carriages per day.

Then Datang's development of Hebei Road will increase ten times, a hundred times.

Today, Hebei Province is poor, miserable, sparsely populated and barren of land.

"A giant bridge with a width of twenty feet and a length of eight hundred feet will bring Tang Dynasty an annual wealth of tens of millions of guan, and the tax revenue of the national treasury will also be tens of millions of guan. How much will Duke Du plan to invest in this bridge?" Li Yuanxing With the thinking of a modern person, he was putting pressure on Du Ruhui.

Fang conspiracy put an end to it!Definitely not in vain.

"His Highness thinks, how many guns are needed?"

"Eight million guan! It needs 800 catties of cement, countless sand and gravel, and millions of catties of refined steel. It will take at least three to five years to complete, and 20 craftsmen will be employed." Li Yuanxing looked excited.

Judging from Li Yuanxing's expression, Li Yuanxing will definitely build this bridge, and the Jinghe Bridge should be a test for Li Chun.

Du Ruhui couldn't make a decision, he didn't dare to speak, 800 million jin didn't frighten him, but a million jin of fine steel really did.

"Of course, it is also possible to change the repair method, similar to the repair method of the Jinghe Bridge. But the Yellow River is different from the Jing River. What will happen if there is a flood and the bridge is destroyed? Then everything will be in vain. Only governance can guarantee the governance of the Yellow River. Flood reduction, and even prepare an alternate waterway, flood discharge area to keep the bridge."

Du Ruhui was completely taken aback. The amount of information Li Yuanxing said had exceeded his mental arithmetic ability. (To be continued.)
