Datang: My father is the head bodyguard

Yuchi Baoqi shook his finger: "Yes, but not entirely. The characteristics of cable bridges are beautiful and majestic, high load-bearing capacity, relatively easy construction, and low maintenance costs."

"At the same time, cable bridges can be said to have the longest span among all types of bridges. They are not even limited to crossing rivers, but can also be used between two mountains."

A researcher raised his hand: "Commander-in-chief, the steel cable on the cable is very important, right?"

Yuchi Baoqi nodded. "Ninety-one steel wires with a diameter of 5.1 mm form a bundle, and ninety-one bundles form a cable. To produce this type of steel cable, we need to design a multi-purpose steel cable compression machine. After compression, steel hoops are placed at intervals to ensure the stability of the steel cable."

Seeing that someone else raised their hand to ask a question, Yuchi Baoqi quickly stopped and said, "I have almost finished talking about the types of bridges. You can discuss the subdivisions and advantages of cable bridges and beam bridges later."

"Now let me tell you about the process of bridge construction. According to the situation at Duke Chi's place, most bridges with small spans use the traditional arch bridge structure, but they replace wood and bricks with reinforced concrete."

"Due to the deadweight of reinforced concrete, many arch bridges with a small span need to add a beam to ensure stability."

"Such bridge construction is indeed very inefficient and unsafe."

"When it comes to bridges with larger spans, Duke Chi chose the beam bridge I drew. There is no need to explain the advantages of this type of bridge. Let's talk about the difficulties, the construction of bridge piles and pier load-bearing blocks."

A researcher who has some experience in bridges raised his hand: "Usually, the water flow is cut off, and workers go down to clean the river, remove the silt, and then compact the riverbed and drive piles."

Yuchi Baoqi tapped his fingers on the table a few times. "It's easier to cut off the water flow during the dry season, but during the wet season, when there's plenty of rain, the project progress will come to a standstill. The Tang Dynasty is now in its heyday, and the road and bridge problems need to be solved urgently. It's impossible to stop the project because of natural causes."

"So I proposed a new way to block the water flow: the cofferdam."

“It’s not a weir like the Dujiangyan weir, but a cofferdam made of earth and stone, concrete, grass and soil, bamboo cages, steel sheet piles and steel casings.”

Yuchi Baoqi took a piece of chalk and wrote down several types of cofferdams on the blackboard. The researchers below, including Mo Qi, picked up papers and pens and began to follow Yuchi Baoqi to record.

"The grass-earth cofferdam is a grass-earth mixed structure. The grass-earth cofferdam can be made from local materials, has a simple structure, is easy to construct, has a low cost, has good anti-seepage performance, strong adaptability, is easy to dismantle, and has a fast construction speed."

"It is generally suitable for medium and small water conservancy projects with a water depth of no more than six to eight meters and a flow rate of less than three to five meters per second."

"Similar projects are basically tributaries that run through the city, small rivers in villages, etc."

Yuchi Baoqi listed all the scenarios in which several types of cofferdams can be used, and also marked the safe construction conditions for various cofferdams.

"Mainly, let's talk about steel sheet pile cofferdam and steel box cofferdam. These two cofferdam methods can be said to be the best in our bridge cofferdam projects. Whether it is a cofferdam across a river, across a river, or even across the sea, these cofferdam methods can be used."

"Some people may ask, since this cofferdam method is so good, why not just use it?"

"If we want to use these two cofferdam methods, we need two types of cranes: floating crane and rail crane. The floating crane is loaded with steel sheet piles and transported to the location where the cofferdam is needed. The crane on the ship then lifts the steel sheet piles and inserts them into the river channel to cofferdam the location where piling is needed."

Researchers in the engineering department are already accustomed to such things. The prerequisites for doing something may be much more complicated than the thing itself, just like the engine.

Punching machines and manual chiseling are enough to produce a powerful engine, but if large-scale production is required, more advanced equipment is needed.

Making these devices is even more time-consuming and labor-intensive than manufacturing an engine. The technology and industries involved are unimaginable to ordinary people, which is why these researchers are so fanatical about technology.

Facing the difficulties ahead, seeking solutions and overcoming them, the joy and sense of accomplishment they gain are the driving force behind these scientific researchers.

Mo Qi made the decision directly: "Xiao Lin, go contact Luoyang Shipyard. We need them to design a floating crane with us."

Yuchi Baoqi patted Mo Qi on the shoulder and said, "Don't be so clear about the engineering department. The headquarters and branches, and even the Luoyang Shipyard, are all partners that the engineering department can trust."

"Let's unite to accomplish great things. We are not afraid of any difficulties. If things get tough, I'll be there to support you."

Mo Qi's eyes were firm: "It was a problem of the engineering department before, and it was also my personal problem. I apologize to you."

Yuchi Baoqi glanced at his watch and said, "It's getting late. I have to go back. Forget about apologizing. I'll go and ask Duke Chi to come to the engineering department some other day and ask him what else needs to be developed."

Mo Qi nodded solemnly, sent Yuchi Baoqi out of the engineering department, and watched him get on the motorcycle.

Nowadays, the lighting of the main roads in the Tang Dynasty at night no longer relies on torches and bonfires. Street lamps on both sides of the road illuminate the entire Chang'an City.

The helmet that Yuchi Baoqi was wearing and the motorcycle he was riding were both painted with the Tianwei Army livery. When the people along the street saw this, they all ran out of the shops on both sides of the road.

"The Tianwei Army will win!"

No one knew who howled like that, but all the people on the street followed suit. The people in charge of security in various areas of the Baiqi Division and the Dali Temple were all overwhelmed.

"Why would a soldier from the Tianwei Army be riding a motorcycle around Chang'an City at night?"

"You've already said that the soldiers of the Tianwei Army would not do this, so who else could it be?"

The chief of patrol of the Hundred Riders and the Dali Temple decided to just pretend that nothing happened and ordered the Hundred Riders and the Patrol Squad to maintain order everywhere and pray that nothing would happen.

Yuchi Baoqi returned to the gate of Duke E's Mansion. He slowed down and saw that people were sitting in a row eating fruit in front of his mansion. He stepped on the accelerator and was about to drive away. Unexpectedly, Chai Shao came out and grabbed the steering wheel of Yuchi Baoqi's car.

"Your Majesty, Your Majesty!"

Yuchi Baoqi stopped the car, took off his helmet and looked at the officials: "What are you doing here? Don't force me to find the Hundred Cavalry and the Dali Temple to arrest you all in the middle of the night."

It can be seen that Fang Xuanling is very angry, his whole face is as stinky as it can be: "Heh, what's the matter? Your Royal Highness the King of England dares to do it but not to take responsibility for it?"

Yuchi Baoqi was really annoyed: "The old lady peed on her instep, it's really a shame, what did I do? What did I dare not take responsibility for? Did I eat your rice?"
