The construction speed of the mixing plant is still quite fast, the foundation here was done last year, and the north is now not good, the winter is too cold, and a lot of work is not easy to do.

It is necessary to prepare relevant plans in advance, the relevant equipment and construction machinery are in place, and the workers are also very hard-working.

Bangs are also walkie-talkies that can't be used, which is much heavier than walkie-talkies.

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.

Now that the plant has been built, there is no way to test it because the outside temperature is too low.

Even the project here is also for civil construction, and fortunately there are excavators, otherwise, it would be too hard for people to do these jobs in winter.

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

There is also a longer building next to it, which is a production plant for passenger aircraft, which is still under construction.

The temperature in the cargo aircraft workshop is not too high, it can only be said that it is not very cold, and it is just right to work in clothes.

Next to the plant, there are two huge plants, which are used for secondary processing and storage of aircraft components.

Bangs' new office is here, and all parts need to be pre-machined.

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

Fortunately, the load-bearing structure inside the propeller aircraft is not as perverted as the jet type.

The skin on the outside of the aircraft itself is very thin, and the cargo plane can directly see the various stressed beams inside the aircraft.

The bangs are here to machine all the parts again and then to make drawings here.

As for the maintenance department, the original Wang Ba has been sent to the Kyoto Zoo, and the little sister has left two small ones.

There is a large indoor exhibition hall at the Kyoto Zoo, and the bangs are not bad.

International affairs, Liu Hai is not clear, now there is no such developed information in later generations, and I don't know that my father-in-law went to Australia to see such a cheap local land, so he bought a very large piece, in the bones of the Chinese people, in fact, they are still very yearning for land.

If you take out the frame of the aircraft alone, it is actually similar to the steel cage of the upper and lower columns on the construction site, with longitudinal beams and beams forming a frame of the aircraft shell, and then the outside is aluminum alloy skin, and the material is all made of superduralumin alloy.

This side starts to make materials, and the other side of the plane starts to be made, and Liu Hai has to take out the drawings made yesterday every morning, and then make them into slides to enlarge, and the next morning he will explain the day's tasks to everyone clearly.

This time, those involved in the manufacture of large transport aircraft are all key technicians in the factory.

This is also what Liu Hai discussed with Sun Aiguo, these technicians personally started to manufacture an airplane from beginning to end, so they can be fully qualified for technical work in the future.

These are a group of college students trained by our factory, after several years of investigation.

From now on, it will be the backbone of the motorcycle factory, in fact, this is also a bangs with students.

There's no way, aircraft manufacturing this kind of thing, you can't do it alone, and now this time it seems to be a bit of a delay, so when these people grow up, you can only talk about it.

These skilled workers were also selected from the manufacturing side of the twin-engine transport aircraft.

These technicians carefully looked at the drawings of the decomposition of the bangs and explained the truth inside.

The distance between each stringer beams on the drawing, the way of welding.

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

The cargo plane is better, there is no high-pressure closed cabin, if it is a passenger plane, it will be a lot more troublesome.

The cargo door is still placed at the tail of the aircraft, and the bangs want to be placed in front of the aircraft, but unfortunately the domestic manufacturing strength does not allow it.

Sun Aiguo will also come here every day to walk around, looking at the big plane that is taking shape little by little, and he walks a little floating.

The propeller transport itself has many lower parameters than the jet transport aircraft because of the speed.

Also because the country now does not have the capacity to create jet transport aircraft.

Historically, in the eighties and nineties, we couldn't make that kind of aircraft, let alone now.

As mentioned earlier, jet transport aircraft can also be manufactured by splicing and welding, but there are more calculations involved.

It can barely be done, but it is not cost-effective to apply it on a large scale in the future, and the overall weight of an aircraft is at least several tons heavier than other aircraft of the same type.

"Look at this progress, it should be completed in three months!" Sun Aiguo watched the progress of the manufacture of the aircraft.

"There is no problem with three months, if it is fast, it will be done in two months." Some of the large accessories here are produced and delivered.

For example, aircraft landing gear, tires, follow-up only need to install the landing gear, tires on the control of hydraulic pipelines.

There is also the integral hatch at the back of the aircraft, as well as the hydraulics.

These bangs are all drawn here, let them be processed elsewhere, and you can just accept them.

Sun Aiguo is envious of Liu Hai's abundant energy, he goes to work here every day, and sometimes he has to study medicine with his sister in the maintenance department on Sundays.

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

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

"This group of people is brought out, and the aircraft department of our motorcycle factory can be regarded as the real first in China." Sun Aiguo looked at the busy workers.

"In terms of transport aircraft manufacturing, we are already the first, is it possible that the factory director still wants to manufacture fighter jets?" Bangs said half-jokingly.

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

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

"Forget it, it's useless to simply make airplanes, you also need supporting radars, missiles, etc., and you need the cooperation of multiple departments and factories." Bangs shook his head, now is not the time.

"It's not the same if we do it ourselves, and it's not like we haven't made ammunition." Sun Aiguo felt that it was nothing, and he never dreamed that his factory would be so big now, and he would produce large aircraft.

Liu Hai is mainly a conductor here, and he didn't go up to work in person, and he will go up to accept it after they finish it.

In addition, the houses standing on this side of the bangs are specially reinforced, even if the entire factory collapses, there will be no problems with the houses here.

Bangs are going to get out of this house, and all the traffic on it has to stop.

There is no way to avoid traffic accidents, and some drivers sometimes have a short circuit in their brains and don't know what they are doing.

"And you said earlier that you want to do a gunship." Sun Aiguo remembered the words of bangs clearly.

Liu Hai could only nod: "I can definitely do it, but it's not necessary, let's do it and it will become a duplicate construction." ”

Of course, Bangs has a plan to do here, not only to do it, but also to make a big brother who comes and goes to fool the north, and exchange good things from them.

As for whether it is a pit or not, who dares to guarantee this, anyway, one hand to pay, one hand to deliver, everyone is voluntary.

"That's it, it's not that we don't do it, it's not necessary to do it."

"The mixing plant is very good, and the cement tanker pump truck can greatly improve the speed of our project construction." Sun Aiguo is full of praise for the mixing plant made by Liu Hai.

And Sun Aiguo found that although the things made by Liu Hai were not very tall, they had a very wide audience.

From the motorcycle at the beginning to the tractor and excavator at the back, the factory also has it, but it is not the main force.

There is no one in the whole world to compare with my own factory, there are too many business contents, and sometimes I don't know how many workshops there are as the factory director, and sometimes the people below come to report the work, and I will forget this workshop.

Liu Hai nodded: "I have a pickup truck plan here, and I will make some heavy vehicles after the transport plane is done, but this heavy truck has high requirements for bridges and road conditions." ”

"We are building cars, not building bridges, and we have done a good job at the mixing plant." When Sun Aiguo heard that Liu Hai was going to engage in heavy vehicles, his eyes also lit up.

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

Pickup bangs just come up with a design plan, and the specific design should be handed over to the automobile manufacturing department, and then he will act as a functional department for acceptance, and he will be redone if he is unqualified.

I really don't have the energy to do this, or is it that I am delaying my development now.

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

Now the high-rise building in Kyoto is a civil aviation building, and it seems to be only 70 meters?

"30th floor?" Sun Aiguo's eyes lit up when he heard this.

Liu Hai said his idea of tower crane again, and the current tower crane just needs to take his hardware into account, winches, wire ropes, and slewing mechanisms.

And then do some force design, as well as make a tonnage table, after all, in the current production environment, some people blindly pursue more than two goods, and do not consider any factory regulations and the like.

It is foreseeable that this kind of accident will definitely happen, after all, there are such accidents in modern times, let alone this era.

As for the designs on other tower cranes in later generations, it is because the floors built are too high, and there are many factors that need to be considered.

For example, if you want to build a high-rise building of several hundred meters, then the wind force above is very large, and this factor should be taken into account when hoisting, whether it is the wind force borne by the tower crane itself on it, or the wind force borne by the items when hoisting.

The difficulty of hoisting at a height of a few hundred meters is not at all the same level as the height of a 30-story building.

Therefore, the tower crane with a height of several hundred meters has more various sensors in itself, and if the sensor data is wrong, it must be stopped.

"It's done." Sun Aiguo heard Liu Hai draw a picture for himself while introducing himself to the general principle.

Of course, bangs will also prepare to make elevators, and this thing is not difficult for bangs to make.

The elevators of later generations have multiple safety designs, but why sometimes there are still some things, this is something that Liu Hai can't figure out.

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

In fact, some things should be mechanical, and if you rely too much on electronic devices, sometimes something will go wrong.

Sun Aiguo walked this way, left the workshop, thought of the 30-story building, and then it was covered with tiles.

Then build a row of houses along the road ahead, like this.

It's exciting to think about, but as for the difficulty of construction, and the materials are nothing to a huge motorcycle factory.

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

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

Sun Aiguo also knows the bangs, and he has a mixing plant, a cement mixer truck, a pump truck, and a tower crane, which are a set of overall 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 skilled workers, of course, talking about aircraft manufacturing.

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

"Liu Gong, what a disturbance!" The person who came in looked at the frame structure of the big plane with bright eyes, and this motorcycle factory was quietly building such a large plane.

"Leader, what wind brought you here?" This is the leader of the railway, since the shield machine, Liu Hai has no intersection with the other party, this time the other party came for something.

Sun Aiguo can't help it, the relationship between the motorcycle factory and the railway can be said to be the best, from the earliest motorcycle exports, the railway to the special train began to have a very good relationship between the two sides.

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

"How?" Liu Hai is a little puzzled here, the technical development of the shield machine does not need to be too fast.

"We don't have a 10,000-ton hydraulic press, we want to streamline and optimize the shield machine." The leader opened his mouth to explain.

After listening carefully to the needs of the other party, Liu Hai understood that the shield machine itself was not used in the splicing method?

The splicing method is thick and heavy, and the splicing method is not stable as a whole after long-term operation.

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

The other party means that the number of spliced parts can be reduced, which can reduce the inspection time and increase the working time.

"It's a bit of a trick." After listening to the bangs, he also felt that it was a bit difficult, and to redesign these spliced parts, the internal structure should also be redesigned, including cutter heads, overhauls and so on.

"We want to ask Liu Gong to make a plan, the specific drawing and design, we will complete it, if it is not done well, let them do it again, Liu Gong does not need to be too anxious." The other party continued.

Liu Hai listened to the meaning of this, as if no one on the other party dared to be the leader?

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

Sun Aiguo jokingly said: "I just said that Comrade Xiao Liu is not available, you just want to come and see, if it weren't for watching you give Comrade Xiao Liu a monthly allowance, you would want to enter our factory." ”

As soon as Sun Aiguo said this, Liu Hai understood, and Sun Aiguo's meaning was very clear, after all, he still took an allowance from the other party, and it was reasonable for the other party to come to him.

As for whether to agree or not, it is completely up to you, after all, the manufacture of large aircraft on your own side is also very important.

"I take this to heart, but there are more things involved, and I will definitely not be able to take it out for a while, you have also seen it, and now I am in a hurry about the project at hand, and your shield machine is still in use." That's all Bangs can answer.

"Xiao Liu, I heard you say that the head of the shield machine can be completely integrated?" Sun Aiguo spoke next to him again.

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

The leader of the railway department left an hour later, and Sun Aiguo said to Liu Hai: "The railway has a good relationship with us, and people have come to the door in person, so I can't greet you in advance." ”

"Railway construction is also very important for our country, and I think it is okay to be able to increase their production speed."

"As for the matter of the die forging machine, I believe that he will definitely report to his superiors after he goes back, and now some projects are constantly being replaced, resulting in the progress of the project being delayed again and again."

"If a few more departments put some pressure on their superiors, then the probability of project replacement is relatively low, and the railway department is now the largest department."

When Liu Hai heard Sun Aiguo's words, he understood the factory director's small abacus, that is, he wanted the railway department to also keep an eye on the matter of the die forging machine.

There are more people staring, so the appropriation is still given to people and the like, and the superiors are more relaxed, of course, it is also to put some pressure on the project side.

"Director, I see." 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 out, and the millions of workers in the railway department can form a huge railway construction team to build railways around the world.

After all, the domestic railways are almost built, how much experience will be accumulated, the railways will go out, and the standards will go out.

There are too many countries with mountains in the world, and in the field of shield machines, we are now in the first echelon, although the overall equipment is a little backward, but as long as the equipment can work, it is good equipment.

"You don't have to worry about this, just keep it in mind, you said yesterday about the tower crane, I found all the people in two days, you come directly to lead, and the house design is not also involved in a lot?"

"Let's do this construction department, they have a lot of special construction talents over there?"

"I think the first 30-story building in our factory should be designed to look better and be a little artistic?" After Sun Aiguo said this, he looked at his bangs.

Bangs understood in seconds: "Okay, I'll ponder here." ”

"You have to have a number in your heart, let's build all the houses along the street in front of us, so that others can see our confidence." Sun Aiguo's next sentence scared Liu Hai, the street in front of the motorcycle factory, is it going to go directly to the outside of the Fifth Ring Road in the future?
