    Guan Fei had just completed the marking work of several universities when the sky darkened and the truck that came to pick them up had already arrived. He could only wait to continue tomorrow.  There were not many people in the cab, so Guan Fei asked the elder Chang Yueming to enter the cab. He, Meng Nan, and guard Li Qing climbed into the truck bed.  As soon as he got in the car, Meng Nan advised him.  "Captain Guan, I think your drawing is too detailed. When you drew the lines, not only did you draw the outer outline of the campus, but also the teaching buildings, experimental buildings, and student dormitories were drawn according to the planning map.  The line is off. Forget it, why are you so careful about the artificial lake? You just draw it according to the plan. This is too time-consuming! " Meng Nan is also very old, although he was deeply shocked by Guan Fei!  , No matter how much you can bear it, you won¡¯t be jealous if others can do it but you can¡¯t.  What to do next, or whatever, when he saw something was wrong, he also took the initiative to put forward his own opinions.  "Isn't that what drawing a line is?" Guan Fei supported Che Bang and was stunned for a moment.  "It was like this during the actual construction, but now you only need to distinguish the locations of each functional area, and there is no need to draw too detailed lines. If you draw all the lines like this, the entire city is tens of square kilometers, crisscrossed by tens of thousands of  I suggest you draw the big frame first. For example, if this place is planned to be an industrial university, then draw the position it occupies with white lines as a basis for construction.  The same is true for other areas. In residential areas, you can draw the lines of the community and streets first, and you can leave the rest to us. Besides, you can¡¯t let us engineering team people watch, right?  We don¡¯t care, but if you raise so many people for nothing, isn¡¯t it a loss?¡± He finally joked with a smile.  That¡¯s true.  Guan Fei found that he had fallen into a misunderstanding, and was still planning the city according to the ideas he used to create game backgrounds.  When making game scenery, he is responsible for the design of a city, how to lay it out, and what buildings should be placed where. He will work hard to complete it.  After planning, in order to determine the location, he would draw an outline where the building is located and indicate the name of the building.  After the overall planning was completed, he came to build models according to different buildings.  But that is done with the assistance of the biological accessory brain, and it doesn¡¯t take much time.  ¡°But doing this in reality seems very inappropriate.  A university campus covers an area of ??dozens of acres, and elementary and middle schools also need more than ten acres. Just walking around the fence takes more than ten minutes.  Then, if the functional buildings inside have to be carefully marked one by one, it will really waste too much time.  According to this progress, in one week, at most the commercial area will be completed.  Next, there will be a huge number of various communities, and the residential buildings are all separate buildings, which cannot be completed in a month.  He decided to accept Meng Nan¡¯s suggestion.  "Well, I'll give you the detailed construction drawings of each unit when I get back. I'll trouble you to make detailed corrections to these drawings." "Have you even prepared the specific construction drawings?" Meng Nan raised his hand.  It was slipping and he almost lost his grip. Guan Fei quickly supported him and waited for him to regain his balance.  The planning map is just a large framework. The land is divided into several boxes. Each box is marked with a color and the construction purpose is indicated.  This test is about the overall layout level. As long as he has a strong sense of the overall situation and a certain knowledge of urban planning, he can accept it if Guan Fei can complete it alone.  But the specific construction drawings are different.  That is to divide a specific building unit in very detail, how deep to dig the foundation, whether the building structure is a frame or a prefabricated board, and the building dimensions of each room must be marked in detail, just like he gave it to Chang Yueming to help review  The calculated architectural drawings are the same.  Guan Fei said that he had completed the construction drawings of every unit in the city. Meng Nan didn't believe it to death.  ¡°This is such a huge workload. Even if all the staff of the Provincial Architectural Design Institute work together and work overtime, it will probably take a whole year to come up with a first draft, and it will take three to five years to complete the detailed revisions.  "Of course it's impossible to complete everything" Guan Fei's explanation made him sigh in relief. Although he knew that this was impossible, he really couldn't bear to face the accidents that Guan Fei brought to him again and again.  I'm sure there will be another "Satellite of David" released.  "My design is like this. Except for a few key projects, most of them are temporarily replaced by modularization. For example, I positioned the No. 1 residential area as a high-end villa, so I designed a unified villa shape.  Then the area is positioned with this specification. Residential area No. 14 is positioned as a small high-rise building with elevators.?I took a specification drawing of a twelve-story elevator apartment building and marked the area.  Power distribution cabinets, communication cabinets, sewer directions, specifications, etc. can all be planned clearly.  During the actual construction in the future, designers will be asked to come up with drawings that better meet the requirements based on the requirements of the residents.  But the general direction is like this. With more specific examples, you can make a judgment about the use and general requirements of the area, and you can also have a basis for grading and other processing.  " Guan Fei explained in detail what the construction drawings he was talking about were about. After listening to his explanation, Meng Nan felt that he could accept it. But when he thought about it carefully, he still felt extremely uncomfortable. Even if it is a model house, there are many  Ah! 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. Meng Nan was really relieved after looking at them. There were not many sample drawings.  There are only about ten types. Each picture is not so detailed, only the appearance, frame, and internal room layout can be used as a first draft. With this overall framework, they can calculate the various parameters required.  , so as to come up with a more detailed preliminary land treatment plan Chang Yueming left with various architectural sketches drawn by Guan Fei. He wanted to go back and use the sketches as a model with his colleagues in the design institute.  , based on the capabilities of various building materials, and after scientific calculations, he finally took out the actual construction drawings. He took not only the architectural drawings of the military camp and the brigade headquarters building, but also the dozen or so drawings that Guan Fei later took out.  Zhang pictures were also taken away. In his words, although these pictures cannot be used as real construction drawings, the exterior design and room layout are very interesting, integrating the advantages of Eastern aesthetics and Western architectural pragmatism, and have great influence on domestic architectural design.  It was of great reference value. Guan Fei had no choice but to draw a new set for Meng Nan. This set was even simpler. It only had the general structure data and room layout, which was enough for the construction team.  Before Ming left, Guan Fei handed him another set of design drawings. This is a cement production line with a daily output of 4,500 tons, including a vertical mill, a rotary kiln, a suspended decomposition preheater, and a cooler.  The design drawings of the main machinery, as well as auxiliary equipment including conveyors, feeders, and crushers are not as unreliable as architectural drawings, but a set of extremely complete production line processing drawings.  Each component has detailed descriptions of materials, dimensions, processing accuracy, etc., and there are no fewer than hundreds of large drawings. In fact, some of the large drawings include manufacturing drawings of several small components.  , if broken down, there will be no less than two or three thousand. As long as the factory has the corresponding manufacturing capabilities, the workers can start construction directly according to the drawings. The domestic cement manufacturing technology and practicality are basically the same as those in the world.  Synchronization. In terms of cement production technology, several landmark advancements are the rotary kiln replacing the gap shaft kiln; the suspended preheating kiln, and the latest precalcining kiln. Among them, the precalcining kiln was produced by Japan's Ishikawa Island Company and Chichibu Cement Company.  In 1971, the research was successful on the basis of the German suspended preheating kiln, but it was only a successful research and has not been put into practical use. Before them, in the 1970s, the country proposed the improvement idea of ??"two-stage calcination, adding a fire at the end of the kiln".  . The project was established that year and the laboratory verification at the Building Materials Research Institute was successful.  Later in 1972, Hangzhou Cement Factory conducted an actual production test of "adding a fire at the end of the kiln" and achieved certain results, but it was ultimately unable to continue due to the movement.  In 1973, the systematic research on four-stage separation and pre-decomposition was carried out again at the Building Materials Research Institute, which was also successful.  Last year (1976), the first industrial trial production was conducted at Shiling Cement Factory in Siping, Jilin, and it was a great success, with output more than doubling. ? ? Domestic and foreign countries have realized the industrial application of preheating decomposition technology for the first time.  Of course, having said that, doing it early is not always the best.  Because domestic manufacturing processing technology is still insufficient, automated processing technology is not as good as foreign countries, and more accurate scientific calculation formulas have not yet been established, manufacturing relies more on experience rather than scientific calculations.  Therefore, since the reform and opening up in the 1980s, a large number of foreign cement production lines have poured into the country, overwhelming domestic production lines.  The production line given by Guan Fei is based on the history of the 1990s, a production line developed by domestic cement production line manufacturers based on their own technical strength after absorbing their own and foreign experience - this time and space.  There are only data drawings of this production line (this is already a branch under the mechanical branch. Only classic products with leapfrog development in technology can be produced).??There is a complete set of technical information to allow students to understand and master it in depth).  The rest of this production line adopts mature foreign designs from the 1980s, but there is a very key technology that we have developed ourselves.  That is, there is a very clear calculation formula for the design of the cyclone volute of the preheating decomposition kiln. You only need to calculate according to the formula to calculate the best design plan.  With this formula, even in the 1980s, foreign manufacturers were still producing based on experience, and the efficiency was about 30% behind.  Guanfei has canceled the automated control system on this production line and is waiting for its own improvements in the future.  The other parts can be made based on the current level of domestic manufacturing as long as the workers work hard, but it will be a little difficult at most.  Cement is currently in short supply in the country. It is a strategic material. A small amount of supply is no problem. 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, he can build thirty five-story teaching buildings in one breath!  Considering that building construction requires waiting for the cement to dry before proceeding with the next step, it cannot be completed in one day.  With one day's cement production, hundreds of construction sites can be started at the same time to meet the rapid and efficient construction progress of the new city.  Industrial construction is a category with large investment and long construction cycle. No matter how urgent it is, it must start from the basics and move forward step by step. There is no need to rush.  In his plan, 1977, 1978, and even 1979 were the years when he laid the foundation.  After that, only when each project is gradually put into use and a team of skilled industrial workers is trained, can one's own strength be brought into full play.  This is a difficult and long process.
