Guan Fei had only finished marking the lines of several universities, and it was getting dark, and the truck that had come to pick them up had already arrived, so they could only wait for tomorrow to continue.

There were not many people sitting in the cab, so Guan Fei invited the older Chang Yueming into the cab, and he and Meng Nan and the guard Li Qing climbed into the car body.

As soon as he got in the car, Meng Nan admonished him.

"Brigadier Guan, I think you've drawn too carefully. For example, when you draw a line, not only the outer outline of the campus is drawn, but also the teaching buildings, laboratory buildings, and student dormitories are also drawn according to the planning map. That's it, you spend so much on the artificial lake, how to plan on the map, you draw it, it's too time-consuming! ”

Meng Nan is also old, although he was deeply hit in front of Guan Fei, his endurance is good, he can't do it if people can do it, and he is not jealous. What should I do after that, or what should I do, when he saw something wrong, he also took the initiative to put forward his opinion.

"Isn't that what it's all about?" Guan Fei leaned on the car gang and was stunned for a moment.

"This was the case during the specific construction, but now we only need to distinguish the location of each functional area, and there is no need to draw too much detail at all. You draw all of them like this, the whole city is dozens of square kilometers, crisscrossing tens of thousands of lines, what day are you going to draw it?

I suggest that the large frame should be drawn first, for example, if this is planned as a technical university, then the position it occupies should be drawn with a white line as the basis for the building.

The same is true for other residential areas, you first draw the boundaries of the neighborhood and the streets, and we can do the rest.

Besides, you can't let us engineers just watch it, can you? We don't care, but isn't it a loss for you to raise so many people for nothing? ”

He finally laughed and joked.

That's right.

Guan Fei found himself in a misunderstanding, and he was still planning the city according to the previous idea of making the background of the game.

When creating a game set, he is responsible for the design of a city, how to lay it out, and where to put what buildings, and he will work hard to complete it. After planning, in order to determine the location, he would draw an outline line on the location of the building, indicating the name of the building. After the master plan was completed, he came to build the model according to the different buildings.

However, it was done with the assistance of the biological auxiliary brain, and it didn't take much time.

But in reality, it would be very inappropriate to do so.

A university campus covers an area of dozens of acres, and primary and secondary schools also require more than a dozen acres of land, and it takes more than ten minutes just to walk around the wall. Then there are all the functional buildings inside, and if you have to carefully line them one by one, it will be too time-consuming.

At this pace, at most the commercial area will be partially completed in a week. Then there are a huge number of various communities, and the residential buildings are all individual buildings, and they can't be done in a month.

He decided to accept Mengnan's suggestion.

"In this case, I will go back and hand over to you the detailed construction drawings of each unit. I'm sorry for you to make detailed corrections to these diagrams. ”

"Do you even have the specific construction drawings ready?" Meng Nan's hand slipped and almost didn't catch it, Guan Fei hurriedly supported him and waited for him to stand firm again.

The plan is also a large frame, which divides the land into several boxes, each box is marked with a color, indicating the purpose of the building. This is a test of the overall layout level, as long as the overall situation is strong, with a certain knowledge of urban planning, Guan Fei can complete it alone, he can also accept.

But the specific construction drawings are different.

That is, for a specific building unit, it is divided in great detail, how deep the foundation is dug, whether the building structure is a frame or a prefabricated panel, and the building size of each room must be marked in detail, just like the architectural drawings he handed to Chang Yueming to help review and calculate.

Guan Fei said that he had completed the construction drawings of every unit in the entire city, and Meng Nan didn't believe it.

This is such a huge amount of work, even if all the staff of the Provincial Architectural Design Institute go on the horse together, I am afraid it will take a whole year to come up with a first draft after working overtime, and the details of the revision will not be completed in three or five years.

"Of course, it can't all be done......"

Guan Fei's explanation made him breathe a sigh of relief, although he knew that this was impossible, but in the face of the accidents that Guan Fei brought to him again and again, he was really not sure if he would release another "big satellite".

"My design is like this, except for a few key projects, most of them are temporarily replaced by modularity. For example, if I position Residential Area 1 as a high-end villa, then I design a villa shape and then position the area as this specification.

The No. 14 residential area is positioned as a small high-rise elevator building, so I took a 12-story elevator apartment building specification map and marked it in the area. Power distribution cabinets, communication cabinets, sewer directions, specification requirements, etc., can be planned more clearly.

In the future, according to the requirements of the residents, the designer will be asked to come up with drawings that meet the requirements.

But the general direction is like this, with more specific examples, you can also have a judgment on the use of the area, the general requirements, etc., and you can also have a basis for leveling and other treatments. ”

Guan Fei said in detail what the construction drawings in his mouth were about.

Listening to his explanation, Meng Nan felt as if he could accept it. But when I think about it carefully, I still feel a lot of twists in my heart.

Even if it's a sample room, there are a lot of them!

With this complicated mood, they returned to the location of the brigade headquarters in Longkang Town.

Guan Fei took out the construction drawings he drew, and Meng Nan was really relieved after reading them, there are not many model drawings, and there are only about a dozen. Each drawing is not so elaborate, only an exterior, a frame, and an interior room layout.

These diagrams can be used as a first draft, and with this general framework, they can calculate the various parameters required to come up with a more detailed preliminary land treatment plan.

That's pretty much it.

……

Chang Yueming left with various architectural sketches drawn by Guan Fei, and he wanted to go back, together with his colleagues in the design institute, using the sketches as a model, according to the ability of various building materials, after scientific calculations, and finally came up with the actual construction drawings.

He took away not only the architectural drawings of the barracks and the brigade headquarters office building, but also the dozen or so drawings that Guan Fei took out later. In his words, although these drawings cannot be used as real construction drawings, the appearance design and room layout are very interesting, integrating the advantages of Eastern aesthetics and Western architectural pragmatism, and have considerable reference significance for domestic architectural design.

Helpless, Guan Fei could only draw a new set for Meng Nan. This set is even simpler, with only general framework structure data, room layout, and other details.

These are enough for the construction team.

When Chang Yueming was leaving, Guan Fei handed him another set of design drawings.

This is a set of 4,500 tons per day cement production line, including vertical milling, rotary kiln, suspension decomposition preheater, cooler main machinery, as well as conveyor, feeder, pulverizer and other auxiliary equipment design.

This set of design drawings is not as unreliable as architectural drawings, but a very complete set of production line processing drawings.

Each part has a detailed description of materials, size, processing accuracy, etc., and there are no less than hundreds of large-scale drawings. Although there are only a few hundred, in fact, some of the large drawings contain several small parts of the manufacturing drawings, if you break them down, there are no less than two or three thousand. In the factory where the manufacturing drawings are obtained, as long as the corresponding manufacturing capacity is available, the workers only need to follow the drawings to start construction directly.

The domestic cement manufacturing technology and practical application are basically synchronized with the international one.

As far as cement production technology is concerned, several landmark advances are the replacement of gap vertical kilns by rotary kilns; Suspension preheating kiln, as well as the latest pre-calcining kiln.

Among them, the pre-calcining kiln was successfully researched in 1971 on the basis of the suspension preheating kiln in Germany, but it was only a successful research and has not yet been put into practical use.

Before them, China put forward the improvement idea of "two-stage calcination, kiln tail plus fire" in 70 years. In the same year, the project was established, and the laboratory verification was successful in the Building Materials Research Institute. Subsequently, in 72 years, the Hangzhou Cement Factory did the actual production test of "adding fire to the kiln tail", and achieved certain results, but it was not able to carry out it in the end due to the movement.

In 73 years, the systematic research on four-stage separation and pre-decomposition was carried out again in the Institute of Building Materials, and it was also successful. Last year (76 years), the first industrial trial production was carried out in Jilin Siping Shiling Cement Plant, which was a great success, and the output was more than doubled.

In China, it is the first time to realize the industrial application of preheating decomposition technology.

Of course, having said that, it's not always best to do it early. Due to the lack of domestic manufacturing processing technology, the automation technology is not as good as that of foreign countries, and the more accurate scientific calculation formula has not yet been established, manufacturing is more dependent on experience than scientific calculation. Therefore, since the reform and opening up in the eighties, a large number of foreign cement production lines have poured into the country, crushing the domestic production lines.

Guan Fei gave this set of production line, is in accordance with the history of the nineties of this century, the domestic cement production line manufacturers, after absorbing their own and foreign experience, based on their own technical strength and developed a production line - this time and space he also only has this set of production line data drawings (this is already a branch under the mechanical branch, only the classic products with leapfrog development of technology will have a full set of technical data description, so that students can have an in-depth understanding of the mastery).

The rest of the production line is based on a mature foreign design in the 80s, but there is a key technology that we have researched ourselves. That is, there is a very clear calculation formula for the design of the cyclone volute of the preheating decomposition kiln, and the best design scheme can be calculated only according to the formula.

Even in the 80s, foreign manufacturers were still producing based on experience, and the efficiency was about 30 percent behind.

This production line has canceled the above automatic control system and is waiting for its own improvement in the future. The other parts are based on the current level of domestic manufacturing, as long as the workers do it carefully, it can be made, and it is a little difficult at most.

Cement, which is currently in short supply in China, is a strategic material, and there is no problem with a small amount of supply, but if you want to build a city, you can only produce it yourself.

With this production line, with a daily output of 4,500 tons of cement and a five-story teaching building, he can build 30 in one go!

Considering that the building has to wait for the cement to dry before proceeding to the next step, it is not something that can be completed in a day. Then his cement output in one day can allow hundreds of construction sites to start construction at the same time, meeting the rapid and efficient construction progress of the new city construction.

Industrial construction is a category with large investment and long construction cycle, no matter how urgent he is, he must start from the foundation, step by step, step by step, and he is not in a hurry.

In his plan, '77, '78, and even '79 were the years when he laid the groundwork. After that, when each project is gradually put into use, and a skilled industrial worker is trained, he can give full play to his strength little by little.

It's a difficult and long process.
