Chapter 390 Busy (first update)
The construction speed of the mixing station is quite fast. The foundation here was completed last year. There is a problem in the north. It is too cold in winter and many jobs are difficult to do.

Relevant plans must be prepared in advance, the relevant equipment and construction machinery are in place, and the workers are also working very hard.

Bangs also uses a walkie-talkie as a last resort, which is much heavier than a walkie-talkie.

It is said that there is already a factory making walkie-talkies. It seems to be some kind of French technology. I don't know if it is the same as what I saw in later generations.

After the mixing station is built, there is no way to test it yet because the outside temperature is too low now.

Even the projects here are civil engineering. Fortunately, there are excavators. Otherwise, it would be too strenuous for people to do these jobs in winter.

The four-engine transport aircraft factory may be the largest factory in China, with a length of nearly 500 meters and a span of 50 meters.

There is a longer factory next to it, which is the production factory for passenger aircraft and is still under construction.

The temperature inside the cargo aircraft factory is not too high. It can only be said that it is not too cold, so it is just right to work in clothes.

Next to the factory, there are two huge factories, which are used for secondary processing and storage of aircraft parts.

Liu Hai's new office is right here, and all parts need to be pre-processed.

For example, the various types of materials purchased need to be processed into appropriate shapes here.

Fortunately, the internal load-bearing structure of propeller aircraft is not as abnormal as that of jets.

Combination welding is sufficient. The outer skin of the aircraft itself is very thin, and the cargo aircraft can directly see the various load-bearing beams inside the aircraft.

Liu Hai will accurately process all the parts here, and then produce the drawings here.

As for the big tortoise originally from the Maintenance Department, it has been sent to the Kyoto Zoo, and the junior sister has kept two younger ones.

The Kyoto Zoo has a large indoor exhibition hall, and Liu Hai went to see it and it was pretty good.

Liu Hai didn't know much about international affairs. There was no information as developed as later generations. He didn't even know that his father-in-law went to Australia and saw such cheap land there, so he bought a huge piece of it. Among Chinese people, Deep down, I actually still yearn for the land.

If you take out the frame of the aircraft and look at it separately, it is actually similar to the steel cage of the upper and lower pillars on the construction site. There are longitudinal beams and cross beams that form the frame of the aircraft shell, and then there is an aluminum alloy skin on the outside. All materials are made of super-hard aluminum alloy. .

Materials are being made here, and aircraft are being made on the other side. Every morning, Liu Hai takes out the drawings he made yesterday and makes them into slides to enlarge. The next morning, he explains the day's tasks clearly to everyone.

Those involved in the manufacturing of large transport aircraft this time were all key technicians in the factory.

This was also agreed upon by Liu Hai and Sun Aiguo. These technicians would personally build an aircraft from start to finish, so that they would be fully competent in technical work in the future.

These are a group of college students trained by our factory and have undergone several years of inspection.

From now on, he will be the backbone of the motorcycle factory. In fact, he can also be regarded as a disciple of Liu Hai.

There is no way, something like aircraft manufacturing cannot be done by one person. Now this time seems to be a waste of time, so when these people grow up, I can only talk about it.

These skilled workers were selected from the manufacturer of twin-engine transport aircraft.

These skilled workers carefully looked at the decomposed drawings of bangs and explained the principles inside.

The distance between each longitudinal beam and cross beam on the drawing, and the welding method.

On a deeper level, why are the dimensions of the material the way they are and how they are calculated.

A cargo plane is better, as it does not have a high-pressure airtight cabin. If it is a passenger plane, it will be much more troublesome.

The cargo compartment door is still placed at the rear of the aircraft, but the bangs would rather be placed at the front of the aircraft, but unfortunately the current domestic manufacturing capabilities do not allow it.

Sun Aiguo would also come here for a walk every day, looking at the big plane that was taking shape bit by bit, and he felt a little drifting when he walked.

The various parameters of a propeller transport aircraft are much lower than those of a jet transport aircraft due to speed.

It is also because the country currently does not have the ability to manufacture jet transport aircraft.

Historically, we could not build that kind of aircraft until the 90s and [-]s, let alone now.

As mentioned earlier, jet transport can also be manufactured using splicing and welding methods, but it involves more calculations.

It is barely possible to do, but subsequent large-scale application is not cost-effective. The overall weight of an aircraft is at least several tons heavier than other aircraft of the same type.

"Looking at the progress, it should be completed in three months!" Sun Aiguo looked at the progress of the aircraft manufacturing.

"There is no problem in three months. If you go fast, it can be done in two months." Some large accessories here have been produced and delivered.

For example, the aircraft landing gear and tires only need to be installed on the controlled hydraulic pipelines of the landing gear and tires.

There are also integral hatches at the back of the aircraft, as well as hydraulic equipment.

The bangs are all drawn here and processed elsewhere. You just have to check and accept them.

Sun Aiguo was envious of Liu Hai's abundant energy. He worked here every day, and sometimes had to study medicine in the maintenance department with his junior wife on Sundays.

Sun Aiguo didn't understand Liu Hai's idea of ​​studying medicine. He thought Liu Hai had any thoughts about his junior sister, but after observing for a while, he found that he didn't seem to have any.

However, Sun Aiguo will not stop what Liu Hai wants to do, but will try his best to make Liu Hai do better.

"With this group of people, our motorcycle factory's aircraft department will truly be number one in the country." Sun Aiguo looked at the busy workers.

"We are already number one in manufacturing transport aircraft. Is it possible that the factory director also wants to manufacture fighter jets?" Liu Hai said half-jokingly.

"Is our twin-engine transport plane considered a fighter jet?"

"It's just that we don't want to do it. If we want to do it, do you think we can do it?" Sun Aiguo asked unconvinced when he heard this.

"Forget it. That thing is useless for simply manufacturing airplanes. It also requires matching radars, missiles, etc. It requires the cooperation of multiple departments and factories." Liu Hai shook his head, now is not the time.

"It's not the same if we make it ourselves. It's not like we haven't made ammunition before." Sun Aiguo thought it was okay. He never dreamed before that his factory would be so big and produce large aircraft.

Liu Hai is here mainly to direct, and does not go up to work in person. He waits for them to finish the work before going up to check and accept it.

In addition, the houses standing on Liu Hai's side are specially reinforced. Even if the entire factory collapses, there will be no problems with the houses here.

Liu Hai wants to leave this house, and all the traffic on it has to stop.

There is no way to avoid driving accidents. Some drivers sometimes have a short-circuit in their brains and have no idea what they are doing.

"And you said before that you wanted to build an armed helicopter." Sun Aiguo remembered Liu Hai's words clearly.

Liu Hai could only nod: "It can definitely be done, but it's not necessary. If we do it, it will be redundant construction."

Of course Liu Hai has a plan to do, not only to do it, but also to make it to fool the big brother in the north and exchange good things from them.

As for whether it will be a scam, no one can guarantee this. Anyway, you pay with one hand and deliver the goods with the other hand. Everyone is voluntary.

"That's it. It's not that we don't do it, it's just that there's no need to do it."

"The mixing station is very well done, and the cement tanker and pump truck can greatly increase the speed of our project construction." Sun Aiguo was full of praise for the mixing station made by Liu Hai.

Moreover, Sun Aiguo found that although the things Liu Hai made were not very high-end, they had a very wide audience.

From motorcycles at the beginning to tractors and excavators at the back, factories also have tall things like that, but they are not the main force.

Speaking of my own factory, no one in the whole world can compare with it. There are too many business contents. Even as the director of the factory, I sometimes don’t know how many workshops there are. Sometimes when the people below come to report on the work, I will forget it. this workshop.

Liu Hai nodded: "I have a pickup truck project here. In addition, after the transport plane is completed, we will make some heavy-duty vehicles. However, these heavy-duty vehicles have very high requirements for bridges and road conditions." "We are building cars, not building bridges. Yes, let’s talk about the mixing station, we have done very well.” Sun Aiguo’s eyes lit up when he heard that Liu Hai was going to build a heavy-duty truck.

In the field of heavy-duty vehicles, only motorcycle manufacturers in China can do the best, and other manufacturers don't even think about it.

Pickup truck Liu Hai just came up with the design plan, and the specific design will be handed over to the automobile manufacturing department. At that time, he will act as a functional department for acceptance, and if it is not qualified, it will be returned and redone.

I really don’t have the energy to do this, or I am delaying my development by drawing now.

Liu Hai then asked Sun Aiguo: "Is the factory director interested in building a 30-story building?"

The tallest building in Kyoto now is a civil aviation building. It seems to be only 70 meters?
"Thirty floors?" Sun Aiguo's eyes lit up when he heard this.

Liu Hai explained his thoughts on the tower crane. The current tower crane only needs to take into account its hardware, including the winch, wire rope, and slewing mechanism.

Then do some leakage design and make a tonnage table. After all, in the current production environment, some second-hand products blindly pursue too much without considering any factory regulations and the like.

It is foreseeable that such accidents will definitely happen. After all, such accidents happen in modern times, let alone in this era.

As for the designs on other later tower cranes, that is because the floors built are too high and there are many factors to consider.

For example, if you want to build a high-rise building several hundred meters high, the wind force above will be very strong. This factor must be taken into consideration when hoisting, whether it is the wind force the tower crane itself bears on it, or the wind force the items bear when hoisting.

The difficulty of hoisting at a height of several hundred meters is completely different from that of a 30-story building.

Therefore, a tower crane with a height of several hundred meters has many types of sensors. If the sensor data is not correct, it must stop.

"Done." Sun Aiguo heard Liu Hai drawing pictures for himself and introducing the general principles to himself.

Of course, Liu Hai will also prepare to make an elevator, which is not difficult for Liu Hai to make.

Later generations of elevators had multiple safety designs, but Liu Hai couldn't figure out why things still happened sometimes.

For example, mechanical anti-slip measures, if it were not for human intervention or other reasons, there would be no problems at all.

In fact, some things should be done mechanically. If you rely too much on electronic equipment, problems will sometimes occur.

Sun Aiguo felt dizzy while walking. After leaving the workshop, he thought of a 30-story high-rise building filled with ceramic tiles.

Then build a row of houses like this along the road in front.

It's exciting to think about it. As for the difficulty of construction and the materials, it is nothing to a huge motorcycle factory.

What Sun Aiguo has to do now is to find a group of people, and then Liu Hai will come up with a plan, and this group of people will design it.

Sun Aiguo knows that once the tower crane is successfully designed and manufactured, the factory will definitely have one more product.

Sun Aiguo also knew about Liu Hai and built a mixing station, cement mixer truck, pump truck and tower crane. These are a complete set of construction equipment.

Sun Aiguo knows very well how much effort our country has invested in construction over the years.

At noon the next day, Liu Hai had dinner and was resting while chatting with other technical workers. Of course, they were talking about aircraft manufacturing.

Sun Aiguo came with one person, and Liu Hai was a little surprised when he looked at the person in front of him.

"Gong Liu, what a bother!" The man who came in looked at the frame structure of the large aircraft with bright eyes. This motorcycle factory was actually building such a large aircraft quietly.

"Leader, what brought you here?" This is the leader of the railway. Since the TBM, Liu Hai has not had much interaction with the other party. What is the purpose of the other party this time?

There is nothing Sun Aiguo can do about it. It can be said that the motorcycle factory has the best relationship with the railway. From the earliest time when motorcycles were exported and the railway started to provide special trains, the relationship between the two parties has been very good.

"We want to optimize the shield machine, but our people there are not capable of doing this." Liu Hai, the other party and Sun Aiguo came to the reception room, and the other party said directly.

"How to optimize?" Liu Hai was a little confused. In fact, the technological development of shield machine does not need to be too fast.

"We don't have a [-]-ton hydraulic press. We want to streamline and optimize the shield machine." The leader explained.

After listening carefully to the other party's needs, Liu Hai understood. Didn't the shield machine itself use a splicing method?

The splicing method is thick and heavy, and the splicing method is not overall stable for long-term operation.

The splicing method is fixed by bolts, and it takes a lot of time to check the bolts every day.

What the other party means is to reduce the number of spliced ​​parts, which can reduce inspection time and increase working time.

"This is indeed a bit difficult." After hearing this, Liu Hai also felt that it was a bit difficult. If these spliced ​​parts were to be redesigned, the internal structure would also have to be redesigned, including the blade, maintenance, etc.

"We would like to ask Gong Liu to make a plan. The specific drawings and designs will be completed by us. If it is not done well, just let them do it again. Gong Liu doesn't need to be too anxious." The other party continued. said.

When Liu Hai heard this, it seemed that no one from the other party dared to be the leader?

"It's okay for Liu Gong to finish manufacturing the big aircraft and then lead our project." The leader of the railway department said again.

Sun Aiguo then said jokingly: "I said that Comrade Xiao Liu is not free, but you have to come and take a look. If you didn't see you guys giving Comrade Xiao Liu a monthly allowance, you would never want to enter our factory. "

When Sun Aiguo said this, Liu Hai understood. Sun Aiguo's meaning was very clear. After all, he still received a subsidy from the other party, so it was reasonable for the other party to come to him.

As for whether you agree or not, it all depends on you. After all, the manufacturing of large aircraft here is also very important.

"I keep this in mind, but it involves a lot of things, and I definitely won't be able to get it out in a while. As you have seen, the leader, I am quite anxious about the project at hand now, and the shield machine over there is still in use. It's up." Liu Hai could only answer like this.

"Xiao Liu, I heard you say that the nose of the shield machine can be made into one piece?" Sun Aiguo said from the side again.

Liu Hai didn't understand what the factory director meant, so he could only follow his words: "That's true, but that requires a large die forging machine..."

The leader of the railway department left after an hour, and Sun Aiguo said to Liu Hai: "The railway has a very good relationship with us, and they came to visit us personally. I can't say hello to you in advance."

"Railway construction is also very important to our country. It can increase their production speed, and I think it can be done."

"As for the die forging machine, I believe he will report it to his superiors after he returns. Now some projects are constantly changing people while they are working on it, causing the project progress to be delayed again and again."

"If a few more departments put more pressure on the superiors, the chance of project replacement will be lower. Besides, the railway department is now the largest department."

When Liu Hai heard Sun Aiguo's words, he finally understood the factory director's little plan, which was to make the railway department also keep an eye on the die forging machine.

If there are more people watching, the superiors will feel more relaxed about allocating funds and giving people to other people. Of course, this will also put some pressure on the project side.

"Director, I understand." Liu Hai couldn't say no just now. After all, railway construction is also very important.

Moreover, Liu Hai also hopes that our railway construction will go global. The millions of workers in the railway department can form a huge railway construction team in the future to carry out railway construction around the world.

After all, the domestic railway construction is almost complete, and how much experience will be accumulated. When the railway goes out, the standards will also go out.

There are too many countries with mountains in the world, and in the field of TBMs, we are now considered to be in the first echelon. Although the overall equipment is a bit backward, as long as the equipment can work, it is good equipment.

"You don't have to worry about this, just keep it in your mind. The tower crane thing you mentioned yesterday, in two days I will have all the people here, and you will be the leader directly. Isn't there also a lot involved in house design?"

"Let's do this from the Construction Department. They have a lot of construction professionals there?"

"I think the first 30-story high-rise building in our factory should be designed to be more beautiful and have a sense of art?" After Sun Aiguo said this, he looked at bangs.

Liu Hai understood instantly: "Okay, I'll think about it here."

"You must have an idea in mind. Let's build all the houses along the street in front and let others see our confidence." Sun Aiguo's next words scared Liu Hai. The street in front of the motorcycle factory is a direct one. Do you want to work outside the Five Rings in future generations?
