Yu Qingyang walked into the construction site with a hard hat.

Now it should have just finished firing the cannon and was going out to slag, and from time to time a dump truck pulled a truckload of gravel out of the cave.

The slag will be transported directly to the Nanshan Zhangwangzhuang Stone Yard.

This gravel will be processed into stones and stone chips over there.

Seeing Yu Qingyang coming, the constructors and technicians of Huayu Second Construction called to report and greeted him.

"Mr. Yu, you're here!"

"How's it going?"

"The progress is okay, we have already entered the hole for 85 meters!" At the tunnel construction site are four college students who have just graduated this year.

"You have to study the construction site, unlike in school, no one will pull your ears to teach you what to do, and no one will punish you for copying your homework because you haven't learned!

However, on the construction site, it's not that if you can't learn, there will be no punishment, and the punishment on the construction site is even more cruel, that is, you can't, you can only watch your classmates and colleagues who enter the company with you become chief engineers and project managers, and you can only continue to be a technician or construction worker, and fight at the bottom!"

"Mr. Wang, each of us is required to write a construction diary, check it every time we have a period of time, and we also require that we can't write the same! Otherwise, we will be punished! It's much more hateful than copying homework!

We were punished for copying the fine management standards of the construction site. The four college students glanced at each other, and a bold student said to Yu Qingyang.

"Oh, that's not bad! Mr. Wang is strict with you, that's cultivating you!

Writing a construction log seems simple, but in fact, the knowledge in it is very deep!

To put it simply, the construction log only needs to record what happens on the construction site and the progress of the project every day.

It is said that he is deeply knowledgeable, because the process of writing your construction log is a summary of your day's work in your heart!

For example, when you write today, you have to think about how to put today's line, what should I pay attention to, if it is me to put the line, how should I put it!

Only in this way, over time, will you be able to grow rapidly!

Let's put it this way, if you don't write a construction log, you will work in the dark every day, and you will do whatever the leader tells you to do!

Do a good job or a bad job, and don't think about it afterwards, you won't be able to become the chief engineer of the company in ten years!

However, if you write a construction log with your heart and constantly summarize and reflect, you will be able to become a technical backbone after a construction site! In this way, if you train two construction sites, you can serve as the chief engineer of the project and even serve as the project manager of some small projects! Yu Qingyang, who is a good teacher, told four college students about his own feelings on the construction site.

"Yes, Mr. Yu!

"Then I'll test you! What are the characteristics of full-section excavation?"

"The characteristic of full-section excavation is that large machinery can be used to reduce the amount of labor!" was the bold student who answered first.

"Hmm, anything else?"

"The excavation is formed at one time, and there is less disturbance to the surrounding rock. ”

"Large working space, less mutual interference! Parallel construction and circular construction can be carried out, which can greatly improve the construction progress!"

"There are few construction processes, which is easy to manage!"

With the one taking the lead, several students replied one after another.

"What is the most likely quality problem to occur during the construction process?" Yu Qingyang then asked.

"The position of the peripheral eye must be laid on the cross-sectional contour line, with a spacing of 50cm, and the allowable error ±5cm. The allowable depth error is ±5cm. ”

"The blasting charging should be carried out according to the drilling and blasting design, and it is strictly forbidden to increase or decrease the amount of charge at will, and accurately control the detonation sequence and the amount of medicine in the surrounding eye holes, ··············"

"It is strictly forbidden to under-excavate within 1m above the arch foot and wall foot·········"

"Partial under-excavation is allowed to be 5cm, and the under-excavation range is not more than 0.1m2 per 1m2············"

"Hehe!" Yu Qingyang smiled, did not evaluate whether it was right or wrong, and said to Wang Yiming, who had just arrived: "Mr. Wang, tell me, are your students right!"

Mr. Yu asked about the most likely quality problems in construction, and you answered some technical measures to control quality and quality inspection standards!"

"But, I see that they control the quality, and that's what they do!"

"Yes! So, what you are talking about is the means of quality control, or quality standards! But it is not the answer to Mr. Yu's question!

Mr. Yu's problem is very simple, the most likely quality problem is the over-excavation of the section!

I told you before, don't just look at it, keep it in your head, but also learn to think and summarize!" Wang Yiming reprimanded with a straight face.

"Got it, Professor Wang!"

These four college students are all top students of Beijing University of Technology, and they have listened to Wang Yiming's class, so Yu Qingyang said that they are Wang Yiming's students, and those students also call Wang Yiming Professor Wang, not Mr. Wang.

"We often say that we need to have a clear goal, what does it mean to have a clear goal?

You know where and what are the points that are prone to quality problems in full-section excavation!

List them one by one, and the rest of the work will naturally be simple, and you will be able to do the work in a targeted manner, control him, and prevent him from having problems!" Yu Qingyang took Wang Yiming's words and continued.

The reason why Yu Qingyang said so much is because these are all manufacturable materials.

An Yuqing has recruited a lot of people, including college students.

However, Yu Qingyang gave an order, regardless of any position, to go to the construction site for three months.

Junior college and undergraduate students are halfway gone at once.

The other secondary school students and technical school students completed their pre-job training and were sent directly to Ajigeria.

Two-thirds of the way has been now.

Many people can't stand the suffering of the construction site and the loneliness of the construction site.

As everyone knows, the construction site is the most tempering place, and only by enduring loneliness can we keep the prosperity.

If you work on the construction site for a few years, you will be more likely to succeed than others, even if you change careers later.

And these four college students stayed after a round of elimination.

The high-achieving students of Beijing University of Technology can endure the loneliness and hardship of the construction site, and they will naturally have a bright future in the future.

This is the project manager of the subcontractor, the chief engineer of the project, the director of the supervision unit, and the project manager and chief engineer of the general contractor have all rushed to the scene.

Yu Qingyang didn't preach, looked at the project manager of the subcontractor and asked, "Mr. Zhao, can you enter the cave now?"

"Yes!"

"Well, let's go inside, I haven't really been in the tunnel that's being dug yet!

I'll learn from you too!"

"Mr. Yu, you are polite, welcome Mr. Yu to guide the work!" Zhao Hongxi hurriedly welcomed.

The group walked into the tunnel under construction.

An excavator in the tunnel is loading gravel onto a dump truck.

"This is a smooth blast, right?" Yu Qingyang looked up at the hole marks remaining on the cave wall just after the blasting.

Hole marks, which refer to the blast holes, the marks left after blasting.

After smooth blasting, there will be holes left on the cave wall, and the more holes left, the better the smooth blasting control.

If the hole mark is less than 80 percent, then there is a problem in calculating the amount of blasting agent.

Further, it is explained that the section of the cave wall exceeds the allowable value of the undercut.

"Mr. Zhao, you've been in the market for almost a month, right?"

"Tomorrow is exactly a month!"

"In a month, I only entered the hole for more than 80 meters, and this progress is not fast!"

"Mr. Yu, the early stage is relatively slow, we have to do more preparations, and it will be fine next month!

We plan to excavate 300 meters in the second half of the month!"

"Well, speeding things up doesn't mean sacrificing safety!

You are experts in dry tunneling, and you have more experience in this area than I do!

I won't say more, just one point, that is, safety cannot be relaxed!" Yu Qingyang did not take long in the cave.

Tunnels that have not been relined are still dangerous.

In addition, the stone powder raised by the slag of excavators and dump trucks is foggy, in short, the environment inside is very bad.

So Yu Qingyang stood inside and walked out.

That's it, and it comes out with ashes and stone foam.

Leaving the tunnel construction site, we came to the bridge construction site not far away.

It has been a month and a half since the Nanjiang Road and Bridge entered the site, and the pile foundation of the bridge has not yet been completed.

Four reverse circulation drilling rigs are drilling.

"Mr. Liang, why are there only four drilling rigs? Your progress is a little slow!" Yu Qingyang opened his mouth with few machines.

By this time, his mentality had completely changed.

In the last life, the last thing he wanted to hear was that Party A shouted that the construction period was slow, and asked for more construction machinery and more construction teams.

Because the increase in construction machinery means that the cost increases.

And there is a possibility of nesting.

Especially like this reverse circulation drilling rig, the towing freight is very expensive, and a drilling rig costs tens of thousands of freight from southern Xinjiang.

However, Yu Qingyang asked Nanjiang Road and Bridge to increase drilling rigs without pressure.

What does it matter to me if you increase the fee?

I only know that if you increase the machinery, you can improve the schedule, shorten the construction period, and my expenses will be relatively reduced.

This is the difference in opinion that comes with different positions.

Or rather, the butt decides the head.

Wherever you sit, think about things from where you start.

"Mr. Yu, this progress is not slow, we guarantee that we can complete the construction task according to the construction schedule!"

Yu Qingyang smiled, didn't answer, and turned to another thing, "The province is preparing to build a new Yellow River bridge!"

"That, Mr. Yu, when does the province plan to start this Yellow River Bridge project?" Mr. Liang's eyes lit up, and he asked pretending not to care.

"Preliminary design is underway now!" Yu Qingyang did not hide it, and replied truthfully.

A project should go through four stages: planning, research, decision-making and implementation.

Carrying out the preliminary design, then it means that the fourth stage, the implementation phase, has been entered.

The last time Yu Qingyang saw Director Meng, it was a feasibility study report.

That belongs to the research stage, and some people say that the feasibility study report is not the decision-making stage?

The domestic process is not, and the feasibility study report is only for leaders to make decisions and make data support.

In fact, the process of many domestic engineering projects is reversed.

For example, in the case of the Yellow River Bridge, the leaders first decided to build the bridge.

Then the people below began to investigate and study and form a feasibility study report.

Therefore, many domestic engineering projects are decided first and then studied.

The preliminary design will give a more detailed investment estimate.

Then, the project is reviewed.

I heard that it has entered the preliminary design stage, and Mr. Liang's heart is even hotter.

I have already begun to think about it, sort out my relationship in Dongshan Province, and see if that relationship can be used.

"The Yellow River Bridge project is a project led by the Provincial Department of Communications!" Yu Qingyang added.

Mr. Liang thought about it for a while, and the person who could speak was a deputy secretary general of the provincial government.

Like, there isn't much to say on this item.

I was a little frustrated.

"The Provincial Department of Transportation intends to hand over this project to our Huayu investment, and our Huayu investment will fund the construction!" Yu Qingyang said again.

Mr. Liang, who was depressed just now, suddenly felt that he saw the light.

"Mr. Yu, you have also seen the strength of our Nanjiang Road and Bridge!

You see, can we participate in the Yellow River Bridge project?

Let's continue to work together!"

"Hehe!" Yu Qingyang smiled.

"Mr. Yu, I'll transfer four more rigs over immediately!

I think several other bridges can also be built at the same time!" Mr. Liang gritted his teeth and assured.

"Haha! Mr. Liang, I also very much hope to continue to cooperate with Nanjiang Road and Bridge and you Mr. Liang!

In the past month and a half, we have seen your management and technology!" Yu Qingyang laughed at this time.

"If you want to participate in the construction of the Yellow River Bridge, you must first complete the construction of the tourist road!

It is expected that construction may start again next fall, so Mr. Liang, you have to hurry up!" Yu Qingyang laughed and patted Mr. Liang's shoulder.

Leaving the bridge construction site, Yu Qingyang then came to the road construction site.

Road construction, there are three mountains to excavate.

At the blasting site, Yu Qingyang met Tang Chaoyang, who came to inspect.

"Mr. Tang, this project is the first project since the reorganization of your company, and there must be no mistakes!"

The mechanical service company led by Tang Chaoyang has changed its name to Huayu earthwork engineering construction company.

Huayu earthwork engineering construction company is now not only mechanical construction, but also applied for blasting qualification.

Able to continue blasting work.

The application for blasting qualification was proposed by Tang Chaoyang.

The biggest difference between their companies is that they are all made up of veterans.

Naturally, there are also many engineers in it.

Engineers with blasting skills, let them drive dump trucks and learn to drive excavators, which is a bit wasteful.

Therefore, Tang Chaoyang proposed to apply for a blasting qualification, which solved the problem of the positions of these engineers with blasting skills.

"Mr. Yu, don't worry! They are all veterans of seven or eight years! They don't have to fiddle with explosives in the army!" Tang Chaoyang assured with confidence.

In fact, this kind of mountain blasting is not very difficult.

Several large rhinestones drilled holes in the mountain, then filled with explosives and detonated.

The difficulty is to calculate the amount of charged explosives.

The progress of the blasting depends on the drilling progress of the water drilling rig.

"This kind of water drilling rig is not expensive, you can purchase a few more!

The progress of the entire tour is on your side's blasting progress!"
