Yu Qingyang walked into the construction site wearing a safety helmet.
The cannons must have just been fired and the debris is being taken out. From time to time, dump trucks pull out loads of gravel from the cave.
These gravels will be transported directly to Nanshan Zhangwangzhuang Stone Quarry.
These gravels will be processed into stones and stone chips there.
Seeing Yu Qingyang coming, the constructors and technicians of Huayu Second Construction came to greet him while making phone calls to report.
"Mr. Yu, you are here!"
"How's it going? Is the progress going well?"
"The progress is going well, we are already 85 meters into the tunnel!" At the tunnel construction site were four college students who had just graduated this year.
"You should follow and study hard. On the construction site, it is different from school. No one will hold your ears and teach you what to do, and no one will punish you for copying your homework because you haven't learned it!
However, on the construction site, it doesn’t mean that there will be no punishment if you can’t learn. The punishment on the construction site is even more cruel. That is, if you don’t know how to learn, you can only watch your classmates who joined the company with you, and your colleagues become chief engineers and project managers.
, and you can only continue to be a technician or construction worker, hanging around at the bottom!" Yu Qingyang's habit of being a teacher came back again, and he educated the four college students who had just joined the company.
"Mr. Wang, requires each of us to write a construction diary, check it every time, and we must not write the same thing! Otherwise, we will be punished! It is much more hateful than copying homework!
We will be punished for copying the standards for refined construction site management." The four college students looked at each other, and a bold student said to Yu Qingyang.
"Oh? That's not bad! Mr. Wang is strict with you. He is training you!
Writing a construction log may seem simple, but in fact it contains profound knowledge!
To put it simply, the construction log only needs to record what happened on the construction site every day and the progress of the project.
He is said to be knowledgeable because the process of writing your construction diary is your mental summary of a day's work!
For example, if you put out the line today, when you write, you have to think about how the line was placed today, what should be paid attention to, and how I should put it if I were to put it out!
Only in this way, over time, can you grow rapidly!
Let's put it this way, if you don't write the construction log, you will be working in the dark every day, and you will do whatever the leader asks you to do!
If you do good or bad work and don't think about it afterwards, you won't be able to become the company's chief engineer in ten years!
However, if you carefully write construction logs and constantly summarize and reflect, you will be able to become the technical backbone after one construction site! By practicing at two construction sites, you will be able to serve as the chief engineer of the project and even the project manager of some small projects!" He is a good teacher.
Yu Qingyang, who had a strong temperament, told four college students about his experiences at the construction site.
"Yes, Mr. Yu! We understand!"
"Then let me test you! What are the characteristics of full-section excavation?"
"The characteristic of full-section excavation is that large-scale machinery can be used to operate, reducing the need for manual labor!" It was the bolder student who just answered first.
"Yeah! Is there any more?"
“The excavation will be completed in one go, with less disturbance to the surrounding rock.”
"The working space is large and there is less mutual interference! Parallel construction and cyclic construction can be carried out, which can greatly improve the construction progress!"
“There are few construction steps and easy to manage!”
With the leader taking the lead, several students answered one after another.
"What is the most likely quality problem to occur during the construction process?" Yu Qingyang then asked.
"The peripheral eye positions must be arranged on the section contour line, with a spacing of 50cm, and an allowable error of ±5cm. The allowable error of the depth is ±5cm."
"The blasting charge should be carried out according to the drilling and blasting design. It is strictly prohibited to increase or decrease the amount of explosives at will. The detonation sequence and the amount of explosives in the surrounding holes should be accurately controlled..."
"Under-excavation is strictly prohibited within 1m above the arch foot and wall foot..."
"It is allowed to under-excavate 5cm locally, and the under-excavation range shall not exceed 0.1m2 per 1m2·············"
"Haha!" Yu Qingyang smiled, without commenting on right or wrong, and said to Wang Yiming, who had just arrived: "Mr. Wang, please tell me, are you students' answers correct?"
"It's a bit off topic! Mr. Yu asked about the quality problems that are most likely to occur during construction. All you answered were some technical measures to control quality and quality inspection standards!"
"But, I think they control the quality and do it according to these things!"
"Yes! So, you are talking about quality control methods, or quality standards! But it is not the answer to Mr. Yu's question!
Mr. Yu’s problem is very simple. In full-section excavation, the most common quality problem is that the section is over-excavated and under-excavated! Just these five words!
I told you before, don’t just read and memorize, but also learn to think and summarize!” Wang Yiming scolded with a straight face.
"I know, Professor Wang!"
These four college students were all top students at Beijing University of Technology and had attended Wang Yiming's classes, so Yu Qingyang said they were Wang Yiming's students, and those students also called Wang Yiming Professor Wang, not Mr. Wang.
"We often say that we need to have clear goals. What do we mean by clear goals?
You know where and what quality problems are likely to occur in full-section excavation!
List them one by one, and the subsequent work will naturally be simple, and you can do the work in a targeted manner to control him and prevent him from causing problems!" Yu Qingyang took over Wang Yiming's words and continued.
The reason why Yu Qingyang said so much is because these are all materials that can be made.
An Yuqing recruited a lot of people, including college students.
However, Yu Qingyang gave an order that everyone, regardless of their position, should go to the construction site and stay for three months.
Half of the college and undergraduate students left at once.
Other technical secondary school students and technical school students have completed their pre-job training and are sent directly to Ajigeria.
We are already two-thirds of the way there.
Many people can't stand the hardship and loneliness of the construction site.
As everyone knows, the construction site is the most training place for people. Only by enduring loneliness can we maintain prosperity.
After practicing at the construction site for several years, even if you change careers later, you will be more likely to succeed than others.
And these four college students were the ones left after a round of elimination.
Top students from Beijing University of Technology, who are able to withstand the loneliness and hard work of the construction site, will naturally have a bright future.
This is the project manager of the subcontracting unit, the project chief engineer, the director of the supervision unit, the project manager of the general contracting unit, and the chief engineer have all arrived at the scene.
Yu Qingyang stopped preaching and looked at the project manager of the subcontracting unit and asked: "Mr. Zhao, can you enter the hole now?"
"Can!"
"Well, let's go in and take a look. I've never been into the tunnel being dug!
I will also learn from you!"
"Mr. Yu, you are very polite. We welcome Mr. Yu to come and guide us!" Zhao Hongxi expressed his welcome hurriedly.
A group of people walked into a tunnel under construction.
An excavator is loading gravel into a dump truck in the tunnel.
"Is this smooth blasting?" Yu Qingyang looked up at the remaining hole marks on the cave wall after the blast.
Hole marks refer to blast holes and the marks left after blasting.
After smooth blasting, holes will be left on the cave wall. The more holes left, the better the control of smooth blasting.
If the hole mark is less than 80%, it means there is a problem in calculating the amount of blasting agent.
A further step is to explain that the section of the tunnel wall exceeds the allowable value for under-excavation.
"Mr. Zhao, it's been almost a month since you entered the market, right?"
"Tomorrow will be exactly one month!"
"In one month, we have only entered the cave more than 80 meters. This progress is not fast!"
"Mr. Yu, the early stage is relatively slow. We have to do a lot of preparation work. It will be ready next month!
We plan to dig 300 meters in the second half of the month!"
“Well, speeding up progress doesn’t mean sacrificing safety!
You are experts in dry tunneling and have more experience in this area than I do!
I won't say much more, just one point, that is, safety cannot be relaxed!" Yu Qingyang did not stay in the cave for long.
Tunnels without secondary lining still have certain risks.
In addition, the stone powder thrown up by the excavators and dump trucks made the place foggy, and the environment inside was very bad.
So Yu Qingyang stood inside and then walked out.
Just like this, when I came out, I was covered in dust and stone.
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 Bridge came on site, and the bridge pile foundation has not yet been completed.
Four reverse circulation drilling rigs are drilling holes.
"Mr. Liang, why do you only have four drilling rigs? Your progress is a little slow!" Yu Qingyang said, "There are 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 was complaining about the slow construction schedule and asking for more construction machinery and more construction teams.
The increase in construction machinery and construction teams means an increase in costs.
And there may be work interruptions.
Especially for reverse circulation drilling rigs like this, the towing freight is very expensive. Towing it from southern Xinjiang costs tens of thousands for a drilling rig.
However, Yu Qingyang asked Nanjiang Road and Bridge to increase drilling rigs without any pressure.
Why does it matter to me if you increase the fee?
I only know that if you add machinery, you can improve the progress and shorten the construction period, and my expenses will be relatively reduced.
This is the different opinions brought about by different positions.
In other words, the butt determines the head.
Wherever you sit, consider the problem from that position.
"Mr. Yu, the progress is not slow anymore. We guarantee that we can complete the construction tasks according to the construction schedule!"
Yu Qingyang smiled, did not answer, and turned to another matter, "The province is preparing to build a new Yellow River Bridge!"
"Well, Mr. Yu, when does the province plan to start the 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 anything and answered truthfully.
An engineering project must go through four stages: planning, research, decision-making, and implementation.
Carrying out preliminary design means that it has entered the fourth stage, the implementation stage.
The last time Yu Qingyang saw Director Meng, he saw a feasibility study report.
That belongs to the research stage. Some people say that the feasibility study report is the decision-making stage, right?
The domestic process is not that, the feasibility study report only provides data support for leaders to make decisions.
In fact, the process of many domestic engineering projects is reversed.
For example, regarding the Yellow River Bridge, the leaders first decided to build the bridge.
Then the people below began to investigate and formulate a feasibility study report.
Therefore, many domestic engineering projects are decided first and researched later.
The preliminary design will provide a more detailed investment estimate.
Then, review the project.
Hearing that it had entered the preliminary design stage, Mr. Liang became even more excited.
I have already begun to think about sorting out my connections in Dongshan Province to see if those connections can be used.
"The Yellow River Bridge project is a project led by the Provincial Department of Transportation!" Yu Qingyang added.
Mr. Liang thought about it and found that the only person who could speak was a deputy secretary-general of the provincial government.
It seems that I don't have much say in this project.
Suddenly I felt a little frustrated.
"The Provincial Department of Transportation intends to hand over this project to Huayu Investment, and we, Huayu Investment, will fund the construction!" Yu Qingyang said again.
Mr. Liang, who had just been depressed, suddenly felt like he had seen the light.
"Mr. Yu, you have also seen the strength of our Nanjiang Road and Bridge!
Look, can we participate in the Yellow River Bridge project?
Let’s continue to cooperate!”
"Haha!" Yu Qingyang smiled.
“Mr. Yu, I’ll bring over four more drilling rigs right away!
I think several other bridges can also be constructed at the same time!" Mr. Liang assured through gritted teeth.
"Haha! Mr. Liang, I 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.
“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 will resume next autumn, so Mr. Liang, you have to hurry up!" Yu Qingyang laughed and patted Mr. Liang on the shoulder.
After leaving the bridge construction site, Yu Qingyang then came to the road construction site.
For road construction, there are three mountains that need to be excavated.
At the blasting site, Yu Qingyang met Tang Chaoyang who came to inspect.
"Mr. Tang, this project is the first since your company was reorganized. 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 engaged in mechanical construction, but has also applied for blasting qualifications.
Able to continue blasting construction operations.
It was Tang Chaoyang who took the initiative to apply for blasting qualifications.
The biggest difference between their companies is that they are all made up of veterans.
Naturally, there are many engineers inside.
It would be a bit wasteful for engineers with blasting skills to drive dump trucks and learn to drive excavators.
Therefore, Tang Chaoyang proposed to apply for a blasting qualification, which solved the job problem for these engineering soldiers with blasting skills.
"Mr. Yu, don't worry! They are all veterans of seven or eight years! They often play with explosives in the army!" Tang Chaoyang assured confidently.
In fact, this kind of mountain blasting is not very difficult.
Several large water drills drill holes into the mountain, then load them with explosives and detonate them.
The hard part is calculating the amount of explosives to load.
The progress of blasting depends on the drilling progress of the water drilling rig.
“This kind of water drilling rig is not expensive, you can buy a few more!
The progress of the entire tour is based on your blasting progress!"
