Assistant Liu has been waiting for this opportunity for a long time.
Pointing at the drawings, he said slowly: "Mr. Dong, patriotic comrades, have you ever thought about it?
Sand is sticky, so even if it is placed on the top of the train, it is difficult to ensure that the sand will flow down smoothly when the valve is opened.
Once an emergency occurs, the sand suddenly solidifies.
Wouldn't that be blinding? "
Engineer Dong's expression was solemn: "Your idea makes sense."
He raised his head and looked at Li Aiguo: "Comrade Patriot, what do you think?"
"How do you see it? Of course you see it with your eyes."
Li Aiguo laughed and said: "The reason why sand is sticky is because it contains water inside, and the gravity of water molecules will bind them together."
"If we fry the sand and remove the moisture inside it, its viscosity will be greatly reduced."
"Coupled with reasonable conveying settings, the sand in the sandbags will definitely flow down smoothly."
Frying sand may sound funny, but it was a common practice in later generations.
In later generations, there were even positions for sand fryers in the locomotive depot.
As soon as these words came out, Assistant Liu's eyes suddenly widened: "Fried sand, this is too unbelievable. Comrade Li Aiguo, don't talk nonsense. This is related to the safety of thousands of trains. You are about to make a big mistake... ..”
Engineer Dong frowned and thought for a moment, then interrupted:
"That's enough! Xiao Liu, when you encounter a problem, you don't want to solve the problem, but you want to question other people's plans."
"This kind of impetuous attitude is unacceptable!"
"The methods adopted by patriotic comrades may seem simple, but they are homespun methods."
“Sometimes, homespun solutions can solve big problems.”
Talking.
He picked up a pen and calculated it on the piece of paper, looked at the final result, and nodded.
"According to the methods of patriotic comrades, as long as they are fried, the sand in the sandbags will definitely flow out smoothly."
Assistant Liu's face turned pale and he forced an awkward smile: "It's me, Meng Lang..."
Dong Gong looked at Assistant Liu indifferently, shook his head slightly, and did not criticize him.
A person with such a lively mind is really not suitable for research. We should find an opportunity to transfer him back to Sifang Factory.
Assistant Liu still doesn't know his fate at this moment, it has been decided by his 'outstanding performance'.
In order to make up for his mistake, he hurriedly served Li Aiguo tea and water.
Subsequently.
Li Aiguo drew the second half of the drawing and made certain optimizations based on the characteristics of the 'August 1st' steam engine.
By this time it was already dinner time.
Just as Li Aiguo was about to say goodbye, the staff from the main construction section sent an aluminum lunch box.
Opening the lunch box, there was fragrant rice and fried soybeans as a side dish.
Under the dim light, the soybeans exuded a greasy luster, and Li Aiguo's Adam's apple trembled after being hungry all afternoon.
Dong Gong stopped his pen and looked at Li Aiguo with great interest.
"How about you, are you interested in working in our Sifang Factory? I guarantee you can eat fried soybeans every day."
Li Aiguo shook his head: "No, my father was a train driver. His last wish was for me to take over his job and make more mistakes for the country."
After entering Sifang Factory, with his ability, he can become at least a ninth-level engineer, and the salary seems to be much better than driving a train.
but.
In the near future, a strong wind will blow in Beijing.
Workers are the safest.
Of course.
The more important reason is that Li Aiguo likes to drive big trains.
Seeing that Li Aiguo was not moved, Dong Gong stopped trying to persuade him and lowered his head to study the drawings again.
Engineers' salary is slightly higher than that of train drivers, but their social status and reputation are far lower than that of train drivers.
It is reasonable for Li Aiguo not to 'change jobs'.
...
The 'sandbag' was just a clever idea and not complicated in structure. It only took Dong Dong two hours to fully understand the drawings.
He put down the drawings, his eyes flashing with light, and he couldn't wait to pick up the phone and shook it violently.
"Please transfer Deputy Director Wang."
After a while, Deputy Director Wang's tired voice came over the phone.
"Old Dong, you'd better have good news."
"Wang Ju, we found a treasure this time!"
Half an hour later.
Deputy Director Wang rushed to the office with a group of leaders.
As soon as he opened the door, Deputy Director Wang laughed loudly: "Old Dong, you better not lie to me this time. For your sake, I stopped the department meeting."
Li Aiguo looked up.
Sure enough, the people following him were leaders from various sections.
Among them is Xing Liuzhu, the section chief of the Qianmen Locomotive Depot.
Xing Liuzhu once represented the locomotive maintenance department and visited Li Aiguo's father at Li's house.
Seeing that Li Aiguo was also there, Xing Liuzhu was stunned for a moment.
In the afternoon.
Xing Liuzhu heard Cao Wenzhi mention that a candidate from the Qianmen Locomotive Depot got double hundred points in the exam and was asked to leave by Dong Gong.
Originally I just thought Dong Gong loved talents.
Now it seems that there is a mystery in this.
Now he can actually get Bureau Wang to interrupt the meeting and come all night long. This guy must have done something terrible.
In the afternoon, Cao Wenzhi also reported Liu Chunhua's embarrassment to Li Aiguo.
Considering that Liu Chunhua had a close relationship with Deputy Chief Liu, in order not to damage the unity of the team, Xing Liuzhu originally planned to talk to Liu Chunhua and comfort Li Aiguo, but the matter was over.
Now he felt that he should reconsider how to deal with Liu Chunhua.
As for how to consider it, it depends on what Li Aiguo comes up with.
Li Aiguo saw Xing Liuzhu staring at him and nodded to him carelessly.
Xing Liuzhu felt happy.
This guy is not timid, he is quite interesting.
You know, in the maintenance section, the section leader is the biggest leader.
In addition, Xing Liuzhu has a serious and demanding character.
Many staff members and train drivers were like a mouse seeing a cat when they saw Xing Liuzhu.
Only veteran drivers like Cao Wenzhi dared to joke with him in person.
The two of them were flirting with each other here, and Engineer Dong had already pulled Deputy Director Wang to his desk.
"Old Wang, look, this is the complete drawing of the sandbag."
Deputy Director Wang looked at the densely packed drawings and frowned: "Old Dong, I am a political worker, and I only have a partial understanding of drawings. I don't understand these technologies, so what do you think this thing is useful for?"
"It's useful, it's definitely useful!"
Engineer Dong straightened his back and said confidently: "I have calculated that as long as the sandbags are filled with sand before each trip, when an emergency occurs, the valve is opened and the sand is sprinkled on the rails. With enough friction, most slide rail accidents can definitely be avoided.”
"That's what I want!"
Deputy Director Wang suddenly became energetic and his gray hair stood on end.
"So far this year, there have been more than 30 slide rail accidents in our main section, resulting in more than 20 casualties and the loss of tens of thousands of tons of materials. We must install sandbags on the top of each train as soon as possible."
He waved his hand: "Mr. Dong, you are the technical representative of Sifang Factory. I am ordering you to immediately send the drawings back to Sifang Factory and let the comrades of Sifang Factory produce sandbag equipment according to the drawings."
"yes!"
"Section Chief Zhang, please immediately coordinate a batch of supplies and send them to Sifang Factory."
"yes!"
"Director Liu, you should immediately set up sand frying departments in each section."
"yes!"
Railway people in this era are full of tension and sense of mission.
With the issuance of orders one after another, even though it was already late at night, the entire work section was still busy like a huge machine.
