After leaving the computer room, He Ku entered another room and picked up the textbooks and wooden blocks on the table.

"I don't talk much nonsense, let's start directly!" As he said that, why put the wooden building blocks where everyone can see them, and then split them.

"First of all, we need to break the whole into pieces and split the model. Please see, the cable-stayed bridge is mainly composed of three parts: cable tower, bridge deck, and cable-stayed cable. Let's simulate these three parts respectively."

"First of all, let's talk about cable-stayed cables. Assume that the cable tower has only two cable-stayed cables that are symmetrical left and right. These two cable-stayed cables pull the bridge decks on both sides."

"According to the force analysis, the left cable, the left force, the right force, and the downward force produce a horizontal left force and a vertical downward force on the cable tower; similarly, the right cable, the right cable, produces a horizontal right force and a vertical downward force on the cable tower."

"Because the force to the left and the force to the right are the same and in opposite directions, the two forces cancel each other out, so the gravity of the bridge deck presses on the cable tower, and finally, the force is transmitted to the ground through the piers below the cable tower."

"But please note that there are two piers on each side of our position, and there are no piers in our central area. How should this force be allocated?"

....

At ten o'clock in the evening, He Ku left here under the pick-up of a special car. The problem of how to repair it was solved, but now there is another more important problem.

That is the problem of materials. Without materials, what can I do if I know how to repair it?

You can't just put a few steel ropes on it. Not to mention the people, such a bridge is afraid that even those who build it will dare not leave!

At this moment, Father Nie suddenly asked: "What are you going to arrange the two engineering ships?"

Hearing the words of Father Nie, why did he hesitate for a moment and asked: "Are you useful?"

Father Nie smiled and said, "This is the only two main 'warships' that can fight against the Dajiang River Project! Can it be useless?"

He Ku was stunned for a moment and had to tell the truth, "I seem to have arranged it, the one stationed next to Jiujiang Bridge."

"Oh, that's good. That's my old army before. It's very brave in combat. If you have the chance, take more care of it." Father Nie nodded and said nothing. This time, he asked them to guard the scene, and he also wanted to ask them to get some food and not be full every day...

The plane quickly returned to Xinye.

He Ku was not laid off the job immediately, but came to the project department of Jingjiu Project and archived the work of Jiujiang Bridge in a written document.

Including exploration issues and fountain matters, the changes plan for the middle section of Jiujiang Bridge were also reported.

Then, He Ku wrote some procurement lists and prepared to send them to Xinye and steel mills along the way through the project department.

Procurement list for the middle section of Jiujiang Bridge.

xx steel beam, specification xx

xx steel tower, specifications xx

After writing the procurement of steel beams and steel towers, why send a telegram to Jianggang directly? This factory is very close to Jiujiang Bridge and requires a lightweight high-strength steel to reduce the weight of the main body while maintaining pressure.

Although this type of steel belongs to the category of special steel and is decades ahead of the era, it is still relatively easy to handle Jianggang, which has been equipped with Xinye equipment.

xx cable laminated cable, specification xx

When writing about the steel cable, why scratched your head and carefully wrote some parameters and requirements. This thing is more technical than the steel tower and steel beam. The cable-stayed cable must be a flexible material that can withstand tension and support the main beam. It can be said to be the "lifeline" of the cable-stayed bridge.

Moreover, the production of cable-stayed cables involves a wide range of fields. It is necessary to learn from the protection technology of large cables. After a certain amount of processing, multiple high-strength steel wires are wound with high-strength materials to form. After that, the surface needs to be hot-extruded with a layer of high-density polyethylene skin, and then the anchors at both ends are installed.

If Xinye had not built a power grid, he would have to ask someone to help in making such things, but now, there is no need at all!

Part of the process of ultra-high voltage grid transmission lines can be processed.

If you get this done, why bother to leave him to the on-duty staff for safekeeping and tell him to come and pick it up tomorrow.

After going out, I yawned, why turn around and go back to sleep?

The conference room of Wuhan Iron and Steel is currently lively.

The cadres of Wuhan Iron and Steel gathered together to hold a meeting and discussed a very important matter, about the Jiujiang Bridge and the development of Wuhan Iron and Steel.

Of course, Jingjiu's big thing naturally alarmed them a long time ago, and they were still not moved because they were waiting for the invitation of the comrades from the Ministry of Metallurgy.

However, the project has been in progress for several days, and there has been no notice or documents from metallurgy for a long time, which surprised them very much.

According to the previous rules, the Ministry of Metallurgy will hold an internal meeting to let the well-known steel companies planting flowers get together, and discuss and divide the big cakes and divide the orders for major projects.

But this time it's a hell!

The steel companies that plant flowers have basically received orders, but Wuhan Iron and Steel Corporation has not!

This has led to the inability of Wuhan Iron and Steel Corporation to take advantage of this wave of dividends and continue to develop, and to lag behind various steel companies!

You should know that giving steel to Jingjiu Project is not only a big order, but also a kind of honor. It will also be engraved in history for a long time and become the medal of Wuhan Iron and Steel!

Everything is because once the Jingjiu Railway is completed, it will become the longest, largest, fastest... the most expensive, most and most advanced ten most railway projects for new plants!

"We are not going to discuss this way! Should we go to the Ministry of Metallurgy and ask Minister Lu Dong?"

"I have to ask. The comrade who called Xinye was always confused and said that this matter was not theirs. I thought that even if it was not hiss, he should help coordinate."

Suddenly, some of them suddenly remembered something and said, "Can it be the ones that Shougang has disturbed? We have snatched their orders before, and they are close to Jingjiu project department. They have gotten the moon first when they are close to the water tower. They have snatched ours?"

After the words came, everyone shook their heads, "What are you kidding? Shougang has that ability? Although they just built a new factory a few months ago, how big can they make in just three months?"

"Yes, it's not a small factory? I used to grab their orders, but it was because they were young. Even if they were given them, they might not be able to eat them. We helped our brothers take on production tasks."

"Stop talking, I see, now I will immediately write an application to the Jingjiu project department, hoping that they can use Wuhan Iron and Steel. We are the big brother's technology and the leader in the flower-growing steel industry. Many steel companies still make steelmaking in civilized ways. How can they compare with us?"

"Yes, yes, if they don't look for us, we'll look for them."

"Write it quickly!"

“Write now!”
Chapter completed!
