In the following time, the second and third... all succeeded.
Yan Jiecheng found some problems until the two hundred meter long rails were welded.
Once the welded rail is relatively long, its own shrinkage force is limited, and the amount of protrusion reserved before welding changes little, so the joint formed is relatively high.
Another question, Yan Jiecheng had thought about before.
That is 200 meters of steel rails, soft as noodles.
The lineman can't turn over with a crowbar as before.
Therefore, its subsequent movement can only depend on the machine.
But there is no big gantry crane in their factory.
"Chief Liu, please go to find Director Wang of the repair factory next door. There are some things that need their assistance."
After hearing what Yan Jiecheng said, Liu Yong probably guessed what Yan Jiecheng thought. Although he didn't know what Yan Jiecheng had to do, he hurried to the contact person over there.
Fan Yao, who guided the workers by the rail, also said: "It is a big problem to solve the problem of the welded rail running, which depends on the workers' hands. This is not only inefficient, but also unsafe.
If it hits people, it's not easy. "
Yan Jiecheng also smiled.
Then he looked at Le Zhiren and Fan Yao and said, "Do you have any good ideas?"
"I've seen that kind of gantry crane, but we can't get it, otherwise it would be most suitable for our rail welding plant."
Fan Yao said regretfully.
Le Zhiren beside said, "Can we lay a layer of cylinder on the ground and push it directly on the ground?"
As soon as he finished, he shook his head and said, "Well, it's no good. These welded rails must be stacked in three or four layers, which is definitely not good."
Both of them shook their heads in frustration after saying something.
Seeing both of them looking at themselves, Yan Jiecheng said with a smile, "I will tell you later when Factory Director Wang comes."
Half an hour later, Yan Jiecheng told Factory Director Wang in detail, and after he asked for the equipment that his factory helped to produce, he was also very happy.
Director Wang left happily after Yan Jiecheng's order for their rail welding plant.
After all, he's got the credit he wanted.
When Factory Director Wang left, everyone looked at Yan Jiecheng.
"Commander in chief, I didn't expect that it could still be like this. You are so tall.
In this way, our rail welding plant has realized mechanization. "
Everyone laughed when he said so.
After all, we did not expect that Commander Yan would carry long rails like this.
Yan Jiecheng looked at Fan Yao's admiring expression on his face and said with a smile, "You can't look at me like that. It's nothing."
Fan Yao was a little suspicious of life and said, "You are nothing?"
Yan Jiecheng said with a smile: "You, we can't do architecture.
Since ancient times, the greatest feature of our construction workers is that they are good at using existing equipment to solve all difficulties.
Just like this time, you see our difficulty is that we can't move the rails.
Do you need a car, and do you need a gantry crane to mount the rails? That's what I told Director Wang.
Let them help us produce a batch of walking manual small gantry cranes.
Although only four wheels are installed on a steel frame and then a chain block is installed, not all the functions we want are realized.
So sometimes when we work, we should focus on solving practical problems. "
Yan Jiecheng's solution to this problem is very simple, that is, weld several small cranes two meters high, and then install the wheels.
When it comes to 200 meters of steel rails, ten of them will go together.
Fan Yao listened to Yan Jiecheng's words as if he had some feeling.
The whole person pondered.
At this time, the project of the Ten Thousand People Auditorium also encountered difficulties.
Mr. Hou walked around the office, smoked another cigarette, and then asked, "Is there really no way to do this?"
Chief Engineer Zhang Jinfu, Chief Engineer Zhu Ruixue and Chief Engineer Zhao Erdong all shook their heads with wry smiles.
Zhu Ruixue said, "We can't do it here, or we should ask well-known experts all over the country for advice. After all, I am responsible for this matter, or I should send a letter now."
When President Hou heard Zhu Ruixue say this, he also ordered a little.
"OK, let's ask the whole country for help."
In order not to block the line of sight, the auditorium has designed a large-span steel truss.
The use of large-span steel trusses instead of columns for support means that 12 large-span steel frames with a height of 7 meters and a span of 60.9 meters will be installed on the east and west walls.
How can such a giant be hoisted to tens of meters high?
In these years, there is really no way.
Therefore, President Hou and Chief Engineer Zhu Ruixue decided to ask the whole country for help.
As you know, all the steel structures used in the auditorium project today weigh about 4000 tons. Among them, the steel beams of the State Banquet Hall weigh more than 1100 tons.
How to lift such a heavy steel beam is a headache for them.
For this reason, we also invited experts of hairy bears, and all the plans we came up with failed.
After all, Mr. Hou didn't give up and went to Mao's office again.
"Old Mao, I'm bothering you."
Maolao also smiled bitterly when he looked at Mr. Hou in front of him.
He said, "Don't place your hope on me. It's the first time I've met such a big component. To be honest, I've been thinking hard for a while and haven't thought of any good way."
When Mr. Hou heard what Mao said, he was also very bitter.
He said, "Although we don't have Hercules, I believe that even if we are like Yugong, we can hang this thing."
When Mao Lao heard this, he suddenly thought of something and said, "When you said that, I thought of a person. Now I'll ask him if he can do something about it."
When Mr. Hou heard this, he immediately saw a light in his eyes and asked, "Mr. Mao, who is this person you are talking about?"
As he picked up the phone, Lao Mao smiled and said, "Hey, let's just say Yan Jiecheng."
Mr. Hou nodded and said with a smile, "Yes, how can I forget him? He may have some ideas."
Yan Jiecheng is doing the first bending test of the welded joint of the whole rail on a 200 ton testing machine.
"Afterburner, afterburner..."
Yan Jiecheng constantly commanded Fan Yao to operate the machine.
At this time, Liu Yong ran to one end of the rail to observe the deformation of the rail along the rail.
"Come on, Chief Liu, come back soon..."
Liu Yong listened to Yan Jiecheng and just left.
"Click, bang..."
There was a loud noise, and the rail broke. The broken rail flew several meters away from both ends.
If he leaves a little late, the consequences can be imagined.
All the people on the scene were in a cold sweat.
Liu Yong was even worse. He was almost killed.
