Section 313 First-class master craftsman next [kind
Bai Erwa stared at the cement board, dazed for a while, and then said slowly: "His Highness said that this board can bear two thousand kilograms! Now it has already weighed two thousand kilograms. I don't know if it will break if I add more iron ingots.
Lose!"
After hesitating for a while, Bai Erwa signaled for someone to put in another ten yuan, that is, one hundred kilograms.
As a result, after another twenty dollars went up, the stone slab was still the same, without any movement.
Will breaking this stone slab make His Highness the King of Qin unhappy? This weight has exceeded the limit mentioned by His Highness by a full 10%. Although there are still three hundred kilograms of iron ingots, Bai Erwa really hesitates.
Li Chun, who was standing aside, did not dare to speak.
After watching the monitor for a while, Li Yuanxing saw the problem. The load-bearing test was not like this. According to the placement method ordered by Bai Erwa, more than 30% of the weight was not borne by the board, but was dispersed to
On the pillar. 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 2,000 pounds to the center of the stone slab, it will definitely be broken.
Thinking of this, Li Yuanxing picked up the walkie-talkie at hand: "Er baby, get close to Li Chun and let Li Chun hear my voice!"
Just the sound of King Qin's voice was shocking enough.
Li Yuanxing said at this time: "Li Chun, I want to ask you. What is the difference between placing these two thousand kilograms of iron ingots like this and placing them all in the middle position?"
"Your Highness, it should be the principle of pole weighing!" After Li Chun came to his senses, he answered with his own knowledge.
People in the Tang Dynasty didn't know about levers yet, but they knew about weighing. The weighing at that time used the principle of leverage.
"The sinners dare to think that if they are all piled in the middle, the stone slab may break!" Li Chun answered respectfully.
"Er baby, break the stone slab. Let Li Chun see the fracture and bring him to see me!" After Li Yuanxing finished speaking, he cut off the intercom.
Walkie talkie!
This thing can be said to be a symbol of the special identity of the Qinwangzhuang Guards. There are only eleven units in the entire Qinwangzhuang. Nine of them are in the hands of people with status in the Guards, such as the front, rear, left, and right gates, and there are five units in total.
, including two at the main entrance. The general on duty is responsible for holding them.
Then Bai Erwa, Lao Lang, and the generals on duty from the left and right battalions each had one.
There is one in the concierge of Li Yuanxing's study courtyard. Li Yuanxing has one in his hand. There is also an immovable one with similar base station function, which is placed in Li Yuanxing's study. An antenna is also erected in the backyard of Li Yuanxing's study.
There is a walkie-talkie on his waist, but it is much more powerful than a famous sword.
Even the imperial palace does not have a mythical call 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 stretched thin and broken.
After removing the iron ingots, Li Chun looked at the fracture for a cup of tea. He could already tell that the stone slab should be made by humans, but he didn't understand how it was made. The steel bars could be increased
The strength is the same as the bamboo tendons. Especially the hollow part, made of bamboo coiled into a circle, is even more wonderful.
After Li Chun left, the broken cement board was carried away. The cement board would be broken into pieces, and the steel bars inside would be taken out and refurbished so that they could be used to build other things.
"Your Highness!" Li Chun entered the small reception room and knelt on the ground.
"Get up and speak. Qin Wangzhuang does not want 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, I will have a chat with you!" Li Yuanxing motioned to Yuanchun.
Pour yourself the tea.
But in front of Li Chun was a cup of goat's milk.
"Drink a cup of goat's milk. Your body is too weak. Take good care of yourself for a few days. I need you to really do great things!"
Li Chun sat in the designated position, and a beam of light shot out from behind him. Li Chun's heart was already a little numb. It was rumored that King Qin of the Tang Dynasty was a star king who descended to earth. It is not surprising that there are any magical things happening in Qin Wangzhuang.
When the light beam hits the cloth, it is a picture.
A detailed drawing of the Zhaozhou Bridge decomposed, this is the masterpiece of later generations of bridge engineers.
"It's a perfect bridge. One more part makes it more, and one less part makes it less. Especially the two small arches can increase the strength of the bridge body and reduce the weight of the bridge body. It can save about 15% of the stone materials and reduce the weight of the bridge body.
The weight can increase the load-bearing capacity of the bridge. The arch is less than half a garden, and twenty-eight small arches are connected to form one big arch. This bridge has three unique features!"
"Thank you for your compliment, Your Highness." Li Chun stood up and saluted.
Li Yuanxing waved to Li Chun to sit down: "The thing you just saw is called a reinforced concrete prefabricated panel. It is made of steel bars, cement, sand and gravel, and water."
The picture changed again, it is a structural diagram of reinforced concrete precast panels.
"You can study this. But I can only give you 10,000 jins of cement, and at most 20,000 jins. And the steel bars only have 1,000 jins of fine steel, and the fine iron nails can give you 10,000 jins. However, I
We only give you four months to build the bridge we want you to build, and the bridge needs to be flat and five hundred steps long!"
Li Chun was surprised, but not surprised.
This is a challenge, a challenge to bridge your own life. With such a bridge, you will die without regrets.
Seemingly guessing Li Chun's thoughts, Li Yuanxing added: "If you are satisfied with only a bridge of 500 steps, then you have let me down. What I ultimately want is, 1,800 steps across the Yellow River."
Bridge. If you want your name to be engraved on a stone after your death, I hope that your name will be on the Yellow River Bridge!"
Li Chun stood up, arranged his clothes very solemnly, and bowed.
Get up, straighten your clothes again, straighten your body again and bow. Then straighten your clothes and kneel down!
"Thousand Steps Stone Bridge! To give you a reference, I imagine you can do better!" Li Yuanxing turned off the projector and placed two pictures on the table. One was the rendering of Marco Polo Bridge, and the other was the design.
Exploded view.
Li Chun has seen this picture once before, comparing it with the half-crazy him and the calm one now.
Now that he had calmed down, he knew the value of this picture.
If the Tang Dynasty did not have a first-class master craftsman, then how would you evaluate these masterpieces of His Highness the King of Qin? If it were said that the Tang Dynasty had a first-class master craftsman, then how would you evaluate the masterpieces of His Highness the King of Qin?
There are already a lot of rumors about Sun Shenxian.
Sun Shenxian has always refused to accept the badge of a first-class physician. People think that Sun Shenxian is being modest and polite.
There should be three rejections before you get the badge of a first-class doctor.
But at this time, Li Chun seemed to understand Sun Laodao's thoughts. In front of His Highness King Qin, you are qualified to receive the first-class badge not because of how high your skills or abilities are, but because of what practical things you have actually done.
Only when you arrive can you wear the first-class craftsman badge with peace of mind.
When Li Chun resigned, Li Yuanxing said again: "Don't think too highly of yourself, and don't underestimate yourself. A good bridge can save people from taking many detours. It can allow food and goods to be transported faster. Its contribution is far greater than
The meaning of a bridge itself is that medicine is the way, and craftsmanship is also the way!"
Li Chun raised the drawing high above his head, bowed before exiting.
The bridge must not only pass people over, but also must not affect the river's transportation capabilities. This is truly a test.
Li Chun went crazy again, this time in a normal way. He asked for twenty clerks for arithmetic, four servants for ink grinders, and a cartload of paper alone.
He wants to calculate, he needs to calculate in detail the magic of Marco Polo Bridge.
He also specially applied for four coils of thousand-foot rope and six horse-drawn carriages.
Li Chun wants to conduct an on-site inspection.
Moreover, Li Chun wanted to test the cement himself, and Li Yuanxing was right.
Du Ruhui came to see Li Yuanxing in person. He came for Li Chun.
"Your Highness, do you think that bridge craftsman is qualified to become a first-class master craftsman just because of one bridge?"
"Du Gong, don't underestimate a bridge. Does Du Gong know the actual benefits brought by a good bridge?" Li Yuanxing asked with a smile.
Du Ruhui pondered for a moment: "If it is true as His Highness said, a Yellow River bridge appears in Lanzhou, then the Tang army can go three thousand miles west without any pressure on logistics. The benefits of the Silk Road will increase by 10%!"
"Toll to cross the bridge can recover the cost of the bridge in five years!"
Du Ruhui knew what Li Yuanxing said was completely irrelevant, and he only thought that Li Yuanxing was joking.
Li Yuanxing sighed lightly: "Actually, I want more than one bridge. What would happen if Feng Lingdu had a bridge?"
A map of the Tang Dynasty flashed through Du Ruhui's mind. The Yellow River cuts off the north and the south. Since ancient times, the Yellow River has no bridges and has to be crossed by boat.
Occasionally when the water flow is slow, there is a simple floating bridge, but there are a few days a year when the water flow is slow.
If there is a bridge at Fenglingdu, the requirements are not too high, and 300 horse-drawn carriages can travel there every day.
Then Datang's development of Hebei Province will increase tenfold or a hundredfold.
Today, Hebei Province is poor, miserable, sparsely populated, and has no land.
"A huge bridge that is twenty feet wide and eight hundred feet long will bring tens of millions of dollars of wealth to the Tang Dynasty every year, and it will also collect tens of millions of dollars in taxes from the state treasury. How much is Du Gong prepared to invest in this bridge?" Li Yuanxing
With a modern person's thinking, he is putting pressure on Du Ruhui.
Fang’s plan is over! It’s definitely not a wasted reputation.
"Your Highness, how many swords do you think are needed?"
"Eight million pounds! It requires 100,000 pounds of cement, countless sand and gravel, and millions of pounds of refined steel. It will take at least three to five years to complete, and it will require 200,000 craftsmen." Li Yuanxing said with excitement.
look.
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 up his mind. He didn't dare to speak. Eight million kilograms of fine steel didn't scare him, but one million kilograms of fine steel really frightened him.
"Of course, you can also change the repair method, similar to the current repair method of the Jinghe River Bridge. But the Yellow River is different from the Jinghe River. What will happen if there is a flood and the bridge is destroyed, then all the repairs will be in vain. Only management of the Yellow River can guarantee
To reduce the flood, we even prepared a backup waterway and flood discharge area to protect the bridge."
Du Ruhui was completely confused. The amount of information Li Yuanxing said exceeded his mental arithmetic ability. (To be continued. Please search Piao Tian Literature, the novel is better and updated faster!)
