The Boss of the Yan Family in Siheyuan

Chapter 269 Multiple choice question?change or eliminate

"Commander Yan, the concrete of the C60 box beams in our factory is different from others.

Unlike other ordinary concrete, some factors have little effect on the performance of concrete with strength grade below C40.

However, it has a significant impact on the performance of C60 and above concrete.

Through a large number of tests, we determined that the water-binder ratio was 0.34 and the sand rate was 38%. In order to ensure that some uncertain factors would adversely affect the workability and strength of the concrete, we conducted more than ten repeated tests.

Check that the average strength value should not be lower than the prepared strength value, and observe the stability of the workability of the concrete mixture.

For each concrete test, a dedicated person is assigned to carefully test the workability, strength, and actual bulk density of the concrete.

When the absolute value of the difference between the actual measured bulk density of the concrete mixture and the assumed one is always controlled within 2%..."

The technical director of Jinmen Box Beam Factory, Yan Jiecheng and Lao Xie, who were inspecting the work, carefully described their box beam production technology.

Under the leadership of the person in charge of the factory, Yan Jiecheng carefully observed every production link.

In the pouring workshop, Yan Jiecheng watched their entire operation process.

They poured the bottom plate first, then poured it in layers from low to high, and then poured the top plate and ribs.

Yan Jiecheng pointed to the workers at work and asked the technical person in charge: "When pouring box beams, how do you control the density of the concrete?"

Lin Gong, the 50-year-old technical manager on the side, said: “For the compactness problem of box girder concrete, we use plug-in vibrators and plate vibrator vibration to solve the problem.

The bottom plate uses an inserted vibrator, and some parts can be struck with a mallet.

The flat vibrators are installed in the same position and have the same power. The vibration is turned on uniformly and the vibration time is controlled at 15 to 25 seconds.

When using a vibrator for insertion vibration, we insert the concrete into the concrete to a depth of 50 to 100mm, and the distance from the formwork should not be less than 50mm to prevent damage to the formwork.

The moving distance of the vibrator is 1.5 times the radius of action of the vibrator, that is, no more than 45-60cm. "

After Yan Jiecheng and the others listened, they all nodded involuntarily.

When the person in charge of the factory and the technical person in charge met Yan Jiecheng, they just looked at him and didn't say much.

They were actually very nervous. They both knew in their hearts that the purpose of their factory and their leaders was to serve the Beijing-Tianjin Passenger Dedicated Line.

If their products are killed by Yan Jiecheng, then their factory will have no value in existence.

Lin Gong, the technical person in charge of their factory, felt a lot of pressure to explain the technology and process of box beam production to Yan Jiecheng and others.

After all, everyone knows that Yan Jiecheng once studied with Mr. Mao, and he can be said to be an industry leader in bridge construction.

In addition, every time Yan Jiecheng’s questions were very standard.Very professional too.This puts more pressure on Mr. Lin.

Yan Jiecheng saw that after the concrete box beams were poured and vibrated, these workers covered and moisturized them in time after the roof was roughened.

Then he asked: "Forest workers, how do you maintain the box beams after the formwork is removed?"

Lin Gong quickly said: "Commander Yan, after the beam is removed from the formwork, we will promptly spray and moisturize it continuously. This process will take no less than seven days."

Yan Jiecheng nodded and said, "Well, Lin Gong, this is very important.

If the maintenance is not done well, the beam body will become cracked, affecting the overall quality. "

Then Yan Jiecheng saw several workers nearby, carrying hand sprayers on their backs, doing maintenance work on the poured box beams.

Then he called one of them over: "Master, can I see your kettle?"

The worker walked over without saying a word. He looked at the factory director and the forest worker first.

Lin Gong smiled and said: "Old Zhang, this is Commander Yan of our superior unit."

The worker named Lao Zhang quickly took off the kettle.He handed it to Yan Jiecheng and said, "Leader, take a look."

Yan Jiecheng took the kettle, opened it and looked to see that the water inside was very clear.

Then I put my hand in and tested the water temperature, which was also within normal levels.

Then he handed the kettle to Master Zhang.

Then, Yan Jiecheng said with a smile: "Okay, Master Zhang, you can go and do your work after I finish reading."

Everyone was a little confused about Yan Jiecheng's actions. Only Lin Gong was thoughtful.

At this time, Lin Gong suddenly looked at Yan Jiecheng and said, "Commander Yan, could this water also affect the quality?"

Yan Jiecheng nodded and then said to everyone: "You may not know.

For the maintenance of concrete castings, this water is very critical.

First of all, we all know that the water used to maintain concrete pouring parts must not be alkaline.

However, one thing that we all tend to overlook is the water temperature.

Just imagine what will happen if a piece of red-hot iron is suddenly thrown into cold water.

Or, a piece of frozen, hard meat is suddenly scalded with boiling water.

Both of these will change the properties of the substance itself.

Therefore, the temperature difference between the maintenance water temperature of box beams and the concrete surface should not be greater than 15°C.

In this season, this problem is not big.But in winter and summer, you must pay attention.

After all, what we are doing is a box beam, which is different from other concrete castings.

The requirements for its strength and tensile capacity are very high.

All aspects of work must be done well, and quality must not decline due to sloppiness in one of them. "

Everyone listened to Yan Jiecheng's words.After thinking about it for a while, I think it does make sense.

They also did not expect that in the production of box beams, even maintenance and water temperature would have such high requirements.

Yan Jiecheng glanced at the factory director and forest workers.

Said: "Our factory, there are no big problems with the production process and technology. Later, the quality inspection department will conduct quality inspections on all your box beams. If they are qualified, then we can leave the factory."

The two people quickly said to Yan Jiecheng: "Thank you, Commander Yan, and the headquarters for recognizing our work."

Yan Jiecheng waved his hand and said, "What do you want to thank me for? This is all the result of your hard work.

If the box beams you produce are unqualified, then no one will dare to let box beams with these problems leave the factory. Do you think this is the truth? "

Everyone laughed after hearing this.

They are not afraid at all of the inspections by the quality inspection department.After all, these box beams have been tested by their factory themselves.

They have already destroyed the substandard products.

After looking at the finished product, Yan Jiecheng and the others looked at the raw materials.Especially for the steel bars, Yan Jiecheng looked at them very seriously and carefully.

Yan Jiecheng took a vernier caliper and carefully inspected the steel bars in each of the several box girder steel keel frames on the production line.

During the inspection, he found that the steel bars used in the beam factory met the design requirements.The steel bars are free of rust and other defects.

The welding of steel cages is also very standardized.The length of the reinforcement is within the design specifications.Therefore, Yan Jiecheng is quite satisfied with the overall inspection of the box girder field.

Of course, there are some other downsides.For example, the output is low, the production efficiency is not high, and especially the product quality control is unstable.

These problems also exist, and they are basically common problems in all factories in this era.

According to the information Yan Jiecheng asked, their defective rate actually reached 10%.

But faced with this situation, Yan Jiecheng had no other good solution.

After all, those older workers have now retired, and the younger workers have not yet grown up.

Today, the backbone of the production force in each unit is actually the workers trained in those ten years.

The technical level of these workers is uneven, and their professional quality is also very different from that of the retired group.

After coming out of the box beam factory, Yan Jiecheng and his group turned left into the concrete sleeper factory next door.

Director Hu of the sleeper factory also worked from noon to afternoon today.I also followed Yan Jiecheng and the others to visit the box beam factory.

When he arrived at his site, Yan Jiecheng said with a smile: "Director Hu, this is your site. You have to give us a good introduction to your factory."

Director Hu heard Yan Jiecheng's joke and said with a smile: "Commander Yan is joking. After all, our factory is not part of the headquarters. We are all your soldiers, and this is not your territory anywhere."

When Yan Jiecheng heard what Director Hu said, he smiled and said to Lao Xie: "Deputy Commander Xie, listen, our Factory Director Hu knows how to talk nicely."

Then, Yan Jiecheng turned to Director Hu and said, "You, if the work is not done properly, there is a problem with the quality of the sleepers. I and the boss at the headquarters will not stop fighting just because of a few nice words."

Director Hu also looked embarrassed when he heard Yan Jiecheng say this.

That's the kind of person he is.

I always like to flatter my boss when I meet him.I always feel that I can’t reach out and hit the smiling person.Anyway, if you keep your posture low, it will be pleasing to the leader, so it won't be too difficult for him.

He has been doing this all these years, always with success.

Unexpectedly, Yan Jiecheng suffered a defeat this time.Yan Jiecheng ignored his remarks and even made fun of him in public.

Therefore, Director Hu quickly corrected his mentality.

He said seriously: "Commander Yan, you can rest assured. Our factory strictly follows the design requirements and the technical documents issued by the command. We have always strictly controlled the quality of sleepers."

Yan Jiecheng smiled and said, "Okay, as long as Director Hu is confident, let's go to the production line and take a look."

When he arrived at the production line, Yan Jiecheng saw that everyone was working in an orderly manner, and he didn't pay too much attention when he saw them inspecting.

Yan Jiecheng couldn't help but nodded, and he couldn't help but think highly of Director Hu.

Unexpectedly, although this person looks a bit worldly on the surface, he also has some real abilities.

In addition to strength requirements, this concrete sleeper also has a key technical issue.That is, there are certain requirements for the pull-out resistance level of anchor bolts.

So Yan Jiecheng specially observed their entire process of anchoring bolts.

I saw a worker mixing sulfur, asphalt, and mortar in a certain proportion.After stirring evenly, this is the special anchoring agent.

Pour the anchoring agent into the reserved anchoring hole of the sleeper, and then insert the bolt vertically.Later, use a small stick to tamp the anchoring agent firmly.

Seeing this, Yan Jiecheng said to Factory Director Hu: "Director Hu, your factory must strictly manage sulfur.

Don't be careless, after all, this thing is.But something happened to the raw materials for the production of gunpowder, and neither you nor I can take the responsibility. "

Yan Jiecheng's words were not a joke.

These days, all workers are like, I regard the factory as my home, and what’s in the factory belongs to my family.

It's common to bring little bits and pieces from the factory.Some people even specialize in stealing production materials from factories.

Anything else is, at best, the loss of national property.But this sulfur is different. If someone really steals it, makes black powder, or sells it, it will pose a huge threat to society.

Therefore, Yan Jiecheng specially reminded Director Hu.

Factory Director Hu heard Yan Jiecheng's reminder and said seriously: "Commander Yan, don't worry. Our factory strictly manages sulfur. We have strictly calculated the amount of each anchor hole.

If the daily application volume of each worker does not match the number of anchors, we will conduct a strict review.

The Janitorial Office also conducts special checks on workers every day. "

Yan Jiecheng nodded and said, "Well, as long as you know the importance of this matter.

However, the anchoring agent is prepared on site, and the proportion is difficult to control, and the anchoring quality is also uneven.

There will also be certain loopholes in the management of sulfur.

Therefore, I suggest that you can research and develop finished anchoring agents yourself or jointly with other units.

Besides, you all must have a market economy mindset.

I estimate that if this finished product is successfully developed, it can not only be used by you yourself, but can also be sold to other units.

Today, we must not wait or rely on anything.

We must learn to develop new products, new processes, and new markets on our own, and proactively seek opportunities.

Otherwise, what will your factories do after the construction of our Beijing-Tianjin Passenger Dedicated Line is completed?Is it going to close down, or is the state spending money to support everyone? "

Not only Director Hu of the concrete sleeper factory was a little stunned after hearing Yan Jiecheng's words.Other factory directors who followed the exchange and studied were also deeply shocked by Yan Jiecheng's words.

They have never thought about these questions.After all, they are all state cadres, and if anyone’s salary is reduced, theirs cannot be reduced.

Factories have always had production tasks and production funds assigned to them from above.

Find your own sales, this is the first time I have ever heard of it.

Therefore, some people sneer at Yan Jiecheng's statement.

If they hadn't seen Yan Jiecheng as their leader, they might have refuted it long ago.

Yan Jiecheng looked at everyone's faces and knew what they were thinking.Knowing that it would be impossible to change their thinking for a while.

I won’t go into too much detail on this issue.After all, changing their ideas cannot be changed with just one or two sentences.

They can only let the general environment force them to change, or they will be eliminated by the general environment.

Change or eliminate, this is not actually a multiple choice question for them.

But a destined ending.

Some people are born with the courage to try, challenge, and have a high ability to accept new things.

Some people are cautious throughout their lives, stick to the rules, dare not try, and refuse new things.

Yan Jiecheng is well aware of this situation.He also knows that the development of the times must be a process of breaking one shackle after another.

If you cannot untie the shackles on yourself in time, you will eventually be eliminated by society.
