Datang: Li Shimin begged me to rebel

Fang Xuanling and the others arrived here quickly, and everyone stood behind Li Shimin. Li Shimin didn't speak, so they naturally wouldn't take the initiative to ask.

After waiting for a while, Li Shimin opened his mouth and said, "You all should know about this bridge?"

"Yes, all the ministers know." Fang Xuanling said.

"I believe that although you all know it, there must be a lot of people watching it for the first time. How do you feel?" Li Shimin looked at the several large ships parked around the piers on the river in the distance, and the steel towers erected around those piers. , I don't know what I'm doing.

"Shocking, I feel like it wasn't done by manpower, but it was indeed built by the workers of the state-owned commercial firms under the Ministry of Construction." Fang Xuanling said seriously.

The others also nodded in agreement. It was indeed the first time for many of them to see this thing, but with such a huge pier, how huge should the bridge be?How broad should its paths be?Does Datang really need such a wide road? !

"Do you now understand why Li Ke carried out the restructuring? Do you think that if the previous system was maintained, the Weihe Bridge of this first scale would be possible?" Li Shimin asked.

Everyone didn't answer, because they probably know the answer now, and they also know that His Majesty doesn't really need them to give an answer, to give an answer.

"Yan Lide." Li Shimin said.

"The minister is here."

"Do you know the detailed information about this bridge? When will it be completed? How much will it cost? Did Li Ke tell you? What did he say?" Li Shimin asked curiously.

"Returning to Your Majesty, it will take about two years to complete the project. It will be extremely expensive. According to His Highness, it will take about two treasuries." Yan Lide hesitated for a moment before he spoke.

"Two libraries? What kind of unit is this?" Li Shimin was stunned for a moment, and asked with some doubts. Others also looked over one after another. They had never heard of this mathematical unit.

"Uh... Your Highness said that if a national treasury is 1000 million yuan, it needs two treasuries." Yan Lide said nervously, there is no way, His Highness said so at the beginning.

Li Shimin: "..."

Everyone: "..."

"Is it necessary to spend so much?" Li Shimin asked with some doubts.

"His Royal Highness said that this is necessary for technical certification. This bridge is used as a technical reserve for the future Yellow River Bridge, Yangtze River Bridge and other great rivers all over the Tang Dynasty." Yan Lide said immediately.

Across the Yellow River and Yangtze River?Everyone is confused, can it really be done?The Yellow River and the Yangtze River are not comparable to the Weihe River, which has a relatively gentle flow and shallow water depth.

But looking at the pier standing in front of him, the height of tens of meters... It seems that it is not impossible?

"Even so, why is the cost so huge?" Li Shimin was a little curious.

"Your Highness said that the cement used for these bridge piers is extremely demanding, and the cost is at least ten times higher than the cement used for paving the road. The steel bars used in the cement gravel are also extremely difficult to manufacture and refine, so it is lead to such high costs."

"However, His Highness said that this is also a good thing. Such a huge capital investment can allow these factories to upgrade their technology. In the future, when the second and third bridges are built, the cost will naturally come down. But even so, His Highness said that Jinqiao Silver Road Copper Houses and bridges are also the most expensive," Yan Lide said.

What Li Ke said is not false, but the fact is true. Datang’s cement production process is not so precise now, although compared with Schrödinger’s cement at the beginning, the quality of the current cement can already be controlled initially.

However, it is still uncontrollable to achieve the quality of the high-strength cement used in the bridge piers, so the current refining method of the cement factory is still restored to the previous Schrödinger refining method.

After refining, number the cement that was independently refined in this furnace, and then use the produced cement to pour some building structures on site. After the cement hardens, test it to see if it meets the standard.

If it meets the standards, the batch of cement will be transported to the construction site. If it does not meet the requirements, it will go to repair roads or do other things, and continue to refine the special cement for bridge piers, which is why the speed of this bridge piers is so slow.

In addition, there are requirements for the cement pouring speed of the bridge piers. For example, how long the cement must be used after mixing, so it is impossible to mix too much cement at one time, or the cement that needs to be poured at one time must be stored for a period of time. In time, we are looking for enough personnel for one-time construction.

What kind of vibrator must be connected to a steam engine, these are more difficult.

All in all, these craftsmen have used various methods. In addition to cement, these craftsmen also have their own traditional methods for enhancing structural strength.

This is why it is slow and expensive. It is also testing a set of standard construction procedures. Thousands of bridge experts!

This is very important for Datang, which has a huge territory in the future.

Although the railway can be built in sections, it is naturally faster to cross the river directly with a bridge.

"Oh, by the way, I haven't asked why the piers of this bridge are built so high." Li Shimin asked again, remembering something.

"His Royal Highness said that sustainable development must be considered in the construction of anything. This is the first bridge over the Wei River, and the height of ships passing in the future will be limited by the height of the first bridge."

"In the future, there may be a second and third bridge on the Weihe River. Once there are more bridges, if we want to navigate larger ships on the Weihe River, it will be impossible, because the bridge cannot be demolished and rebuilt." Yan Lide opened the mouth.

Yan Lide's words made everyone around silently nod their heads. As expected of His Highness King Qin, with this perspective on the overall situation, it can be said that the entire court could not find a single person.

Compared with the solemn atmosphere of the ministers, the atmosphere of Changle and the others is much more relaxed. They are all looking at everything in front of them with amazed eyes and tone.

The stay at the pier was just an episode. There were boats specially used for ferrying. Not only did everyone cross the river, but everyone's carriages also crossed the river.

After crossing the river, the train station was not far away. Soon, a huge building appeared in front of everyone. When they saw this station, everyone was a little dazed.

It stands to reason that a building with such a large area is often either a factory or a palace, but it obviously looks like nothing here.

Its architecture as a whole is mainly practical.

When they arrived, Li Ke was already waiting here.

"Sanlang, why did you ask us to come today?" Li Shimin said unceremoniously when they met.

"Hey, father, I called you here to show you the brand new fairy tale of Datang."
