The head of the vertical centrifugal pump cannot be reached, so it is better to put it forward now than to finally pull off the skin and add a stage to lift water.

Make changes in the direction you want.

There is a problem here, which I have just pointed out, that is, in the project list quotation, not all sub-projects make money.

For example, the water pumping station is basically a state of losing money.

The water pumping station loses money not because the price is not suitable, but because the amount of work is small, although the sparrow is small, although the sparrow is complete, although the water pumping station is only twelve or thirteen square meters, but it is the same as building a house, a process is a lot.

As a result, every process is worked, and some recyclable materials cannot be recycled, such as templates.

In addition, the pumping station is built on a hill, and the transportation of building materials is a problem.

As a result, the water pumping station lost money.

No one mentioned this matter, Yu Qingyang just clicked it, and then mainly emphasized the quality.

It is to clearly tell Wan Guoxiang and Huang Debin that it doesn't matter if you want to pursue profits, but you can't sacrifice quality.

After the meeting in the conference room, Yu Qingyang went to the construction site again.

The road is not very easy to walk, but an excavator is simply cleared out of a dirt road, on which some gravel is padded, barely enough to ensure the passage of trucks transporting steel pipes.

Yu Qingyang did not say anything about this, this is the characteristic of water conservancy projects.

If you want to harden the construction road along the pipeline, the project department can't afford this cost, and the construction road is 10,000 yuan per kilometer, which is only enough to repair such a road.

On the mountain, there are still many places where it is impossible to build roads at all, so you can only rely on manual lifting of steel pipes to the mountains little by little.

The pipes connected to the water system are laid and welded from the ends.

Along the gravel road, all the way up, more than two kilometers of pipe welding have been completed.

It's the middle of April, and it's the rainy season with two more children!

You are now laying along the old ditch, once it rains heavily, this old ditch is estimated to be unable to work for a few days!"

"We are now urging the owners to speed up the relocation work!

Then work at both ends and rush to the middle!" Wan Guoxiang hurriedly explained.

"Hmm!" Yu Qingyang nodded, "By the way, when did you submit the report on the purchase of the micro tunneling machine?"

"I just handed it over to Mr. Chen yesterday, and I should report to the Finance Department today!"

"Well, I'll ask you when I go back, hurry up and give you the money, hurry up and buy machinery, and the connected tunnel can also be constructed at the same time!" Yu Qingyang nodded with a smile.

In the conference room just now, he was a little puzzled, why didn't he see the report on the purchase of the micro tunneling machine submitted by the project department.

It looks like the finances are under review.

The finance department of Huayu Investment has a very complete management system.

Every month, each subsidiary, department and project department must submit a plan for the use of funds.

That is, how much money you want to use next month and where you use it, you should report it a month in advance and do it in advance.

Of course, in order to deal with some emergencies, the CEO of each subsidiary, the department head, and the project manager have a reserve fund in their hands, and this money is used first and then reviewed.

In addition, there is a report on the purchase of a micro tunnel machine such as that submitted by the water system connection project.

This is a temporary procurement, and the approval is more stringent, not only the CEO of the subsidiary must sign, but also the head of the audit department, the chief financial officer, and finally Yu Qingyang can sign.

Ad-hoc purchases, the probability of rejection is more than 80%.

Yu Qingyang asked, but he was afraid that Wan Guoxiang was stupidly waiting for the group's approval to purchase machinery, but they didn't know where their report had been rejected.

"Xiao Duan, about this matter, you go back to the finance department and ask to see if you have received the report!"

"Thank you, Mr. Yu!" Wan Guoxiang hurriedly thanked.

He knew that if Yu Qingyang's assistant asked, then there would definitely be no problem with their procurement report.

"Okay, that's all for today! Overall, it's good, but in warehouse management, pipe stacking, we still need to work harder!

The storage of consumables such as welding rods was a little messy and were stacked directly on the ground.

Also, the steel pipes are stacked a little high, and there are potential safety hazards!

The project assessment is about to start, and Zhang Fusheng, a foreigner, is not as easy to talk as I am!

Other places are very good, if you are deducted points on the warehouse management, you Mr. Chen is not as simple as scolding!

This assessment is directly related to the allocation of the next project!" Yu Qingyang smiled and pointed out the problems existing in the water system connection project department.

"Yes, Mr. Yu's criticism is right, we will correct it immediately!" Wan Guoxiang hurriedly admitted his mistake.

didn't dare to open his mouth to leave Yu Qingyang to eat, Yu Qingyang shook hands with Mayor Zhang and said goodbye, and refused his stay.

Then I ran around several construction sites around the spring.

Although it is a superficial view, Yu Qingyang can point out that they have problems at every construction site, and every problem can be to the point, instead of clichés and empty words such as "you must strengthen management, strengthen quality management, and safety education".

Let every project department be convinced.

Even Wu Yunfang, who followed Yu Qingyang to inspect, was convinced, and couldn't help but sigh that success is never a fluke.

Every construction site can convince a group of project managers in their forties from the technical level and the management level.

This is not something that the average person can do.

In the evening, Yu Qingyang continued to pick up Xia Xue from work, and then went back to the hotel to watch a movie.

…………

The next day, Yu Qingyang signed the purchase report that Xue Qin had brought over before leading the team to leave the spring.

Depart for Jeju.

The spring water goes to Jeju, and the highway has been opened to Confucius.

From the highway to Jeju, some of the roads are not easy to walk, and there are many large cars.

It wasn't until we arrived in Yanzhou that the road conditions got better.

The scenery outside the car window quickly receded, and Yu Qingyang sat in the back seat, closing his eyes and resting.

Yesterday was a little overworked, because I knew that Yu Qingyang was going to Jeju, and then to Peony City, Beijing, I would not see each other for several days, and I was going to Ajigeria at the end of the month, Xia Xue was a little crazy.

Once again, it has been proven that there are only tired oxen, not ploughed land.

The car was parked steadily in front of the Canal Hotel.

The Jeju Municipal Party Committee and Municipal Government have prepared a sumptuous lunch and are waiting for Yu Qingyang.

Because they still had to work in the afternoon, everyone didn't drink much, only served two bottles of Moutai, and everyone got one glass.

In the afternoon, in the conference room of the municipal government, a scheduling meeting of the old canal project was held.

It is still the architectural design institute that first reports the design plan for the renovation of the municipal pipe network.

This time, it was finally generous, not only the maximum rainstorm intensity was calculated, but the pipe diameter was also much more conservative.

The main network directly selected the 2400 tertiary pipe.

Concrete pipes are divided into two types: plain concrete pipes and reinforced concrete pipes.

According to the wall thickness, crack load, failure load, and different internal water pressure, the reinforced concrete pipe is divided into a primary pipe, a secondary pipe, and a tertiary pipe.

Among them, the first-stage pipe has the thinnest wall thickness and the worst pressure-bearing, and the third-level pipe has the thickest wall thickness and the best pressure-bearing.

The first, second and third grade reinforced concrete pipes can be used for pipe jacking construction, and the selection of several levels of pipes mainly considers the external pressure, that is, the depth of soil covering.

The minimum covering depth of the pipe jacking pipe is not less than 1.5 times the outer diameter of the pipe jacking.

For example, for pipe jacking with an inner diameter of 2400, it is necessary to choose a third-grade high-grade reinforced concrete.

"Mr. Yu, what do you think of the design plan of the Architectural Design Institute?" After the report of the Architectural Design Institute, Zhang Hua asked.

The main decision of this scheduling meeting is Yu Qingyang.

After all, none of them are well versed in engineering.

"I don't have any opinions, only one point, that is, the interface of the concrete pipe, I suggest changing it to an F-shaped steel socket!

Long-distance pipe jacking is most likely to cause problems such as interface misalignment, pipe end damage, pipe interface leakage, pipe wall cracks, and pipe wall leakage.

Compared with tongues and grooves, F-shaped steel sockets can effectively protect the pipe end, and the stress area is large, the interface has a good anti-seepage effect, suitable for long-distance pipe jacking, and the applicability of curved pipe jacking is better than that of tongue and groove. Yu Qingyang was not polite, and directly pointed out the problems in the plan of the architectural design institute.

"Hehe, Mr. Yu is worthy of being an expert, and those of us have also seen the plan of the architectural design institute before, but we have not found any problems.

Unexpectedly, Mr. Yu could see it at a glance!" Zhang Hua smiled and excused the somewhat embarrassed designer of the architectural design institute.

"Experts can't talk about it, when I decided to use pipe jacking construction, I specifically looked for information to study it.

I'm also learning and selling now!" Yu Qingyang said modestly.

"If there is no other problem in the renovation of the municipal pipe network, then let the architectural design institute start to deepen the design! Come up with the construction drawings in the shortest possible time!" Zhang Hua saw that Yu Qingyang had no other opinions, and made a decision.
