Great Power Project

Chapter 450 The gap between being able to do it and not being able to do it (ask for a monthly ticket!)

The relocation is a matter of Party A. The legal person of this project should be the Nanshan Water Conservancy Bureau. Yu Qingyang does not want to get involved in the relocation.

Just now I just asked casually about difficulties, but it does not mean that all difficulties are solved for them.

In general, Yu Qingyang is satisfied with the work of the Water System Connectivity Project Department.

Now the most commonly used rock pipe jacking is artificial pipe jacking, rock blasting on the excavation face, manual cleaning of debris, trimming, and then jacking!

The cost of this method is relatively low, but the disadvantage is that it is highly dangerous, especially the tunnel section of the connecting project is small, and the space inside the tunnel is small. Once a danger occurs, rescuers cannot rescue it.

China's tunnel technology is very mature and advanced, but how would a layman know that almost every tunnel has a tunnel where human life is sacrificed.According to official statistics, there will be one life per [-] kilometers of tunnels on average. In fact, this data is relatively conservative, and the real situation should be one life per kilometer.

Laymen are proud of China's infrastructure strength, but they don't know that our technology is piled up with human lives.

For the mountain tunnel connection of the water system connection project, manual tunneling can also be used for pipe jacking, but the project department did not stick to the rules and adopted the most common and cheapest manual pipe jacking, but chose relatively advanced micro-tunnel machines and mechanical tunneling.

This can not only greatly improve the progress of the project, but also ensure greater safety. Most importantly, it can increase the company's construction technology accumulation.

What does Yu Qingyang value most now?
two!

One is safety, state-owned enterprise management, safety first.

To put it bluntly, if there is a safety accident, it is a trivial matter to pay some money. The safety accident will become a stain on the company and Yu Qingyang's life, which cannot be washed away.

Maybe no one can do anything to him, but a stain is a stain.

The second is technology, the improvement of construction level, and the innovation of technological process. Only in this way can we continuously increase our competitiveness and get rid of the situation of competing for food with a group of local enterprises at the bottom.

Among the participating units in the project construction, the construction unit is the bottom. Some people joke that the construction unit is father, the supervision unit is grandma, the design unit is grandfather, and the construction unit is son.

The construction unit is difficult!

Anyone can slap you!

Sometimes, even the construction team below dare to howl at you!

There is no way, the people below howl at you, you can only listen, who told you not to pay?

However, does the construction unit have the final say on whether to send money or not?

Not counting, the money is with the owner's father, if he doesn't pay, how can the construction unit get the money to send it down?

The construction unit doesn't print money either, and advances the funds in the early stage, so it can't always be the advances in the future?
No one's money is blown by strong winds, and no one can carry dry food to work.

Facts have proved that those contractors who work with dry rations on their backs die miserably in the end.

Therefore, if the construction unit wants to live a better life, it can only strive for the upper reaches and strive to improve its own quality and its own conditions.

Facts have also proved that the larger the project and the higher the scientific and technological content of the project, the greater the right to speak of the construction unit.

This is like a municipal road, which can be done by construction units with a third-level qualification. Such municipal roads are often financed, but when the project starts, the financial mother who manages the money only has [-]% of the project funds, or even simply There is no budget for a penny, but because of the request of the superior, it is necessary to bite the bullet.

As a result, the owner asked the construction unit to advance the work, or delay the audit payment.

Are you doing it or not?
quit?There are hundreds of construction companies waiting in line behind.

You can only bite the bullet and do it!

However, if you change to a cross-sea bridge, you will definitely strictly follow the laws and regulations. Before the start of the project, if the construction period exceeds one year, at least 30.00% of the construction funds will be transferred to the special account, and if it is less than one year, at least 50.00% funds to a dedicated account.

And the source of follow-up funds also has a clear source and arrival time node.

Such a project can only be truly realized by the construction unit. According to the book, both parties to the contract are on equal footing.

Applying the concept of family, those projects with low technical content, just like in the past 70s and [-]s, have more sons in construction, and the more they are, the less expensive they are.

If you dare to pierce, you will be beaten if you want to be beaten, and you will be scolded if you should be scolded. Even if you don't prick, you still want to give you away!
As for engineering projects with high technological content, they belong to families in the 90s, and the construction sons are all only children, so fewer children are naturally more precious.

Occasionally pricking, grandparents, parents will also pamper and coax.

I'm afraid that if you don't eat, it will affect your physical development, affect your study, and so on.

"The distance connected by the pipeline is as long as 124 kilometers. I just took a look at the blueprint. The water level elevation of Wolongshan Reservoir is 145, while the elevation of Xingquan River at the end is 21. The height difference between the two is [-] meters. Have you calculated whether the two water pumping stations can meet the designed pipeline pressure?" Yu Qingyang roughly flipped through the drawings and asked.

"The two water pumping stations use vertical pipeline centrifugal pumps with a flow rate of 100m/H, a head of 50m, and a maximum power of 30KW, which should be able to meet the design requirements!" Huang Debin said after looking down at the drawings.

"Don't be superstitious about the Design Institute. You have to have your own opinions. The frictional resistance of a pipe with a length of [-] kilometers, and I just looked at it. There are many elbows, and the resistance of the elbows is not small. You You have to calculate by yourself, how much is left after subtracting the resistance of the two pumping stations, that is, the power of the two vertical centrifugal pumps? Can the design lift meet the pressure required for the pipeline to lift water?" Yu Qingyang reminded with a smile said a word.

Of course, even in the end, the design head cannot meet the actual demand, and it is not the reason of the construction unit, but it is always troublesome.

But looking at the design parameters, the two vertical centrifugal pumps have a total head of 100m and a total power of 60KW, which seems to be no problem. However, although Yu Qingyang did not calculate it carefully, he felt a little unreliable based on past experience.

"Now that I know Mr. Yu, I will calculate it later. If the design requirements are not met, I will file a report and ask for a change in the design and increase the power of the centrifugal pump!" Huang Debin agreed without arguing.

"Actually, apart from increasing the power of the centrifugal pump, there is another method, which is to maximize the effective use of the head of the centrifugal pump, lift the water to the top of the mountain, and then use the pressure of the water itself for long-distance transport!"

This is actually easy to understand. It is to use a centrifugal pump to lift the water to the nearest hill, and then go all the way down, so that the water flows in the pipeline by itself.

The water is lifted to the nearest hill, the conveying distance is short, there are few elbows, and the effective utilization of the head of the centrifugal pump is high.

Instead of slowly going uphill all the way like now, the friction of the pipeline and the resistance of the elbow will increase layer by layer, and eventually consume all the head of the centrifugal pump.

Of course, Yu Qingyang's suggestion is not without its shortcomings, that is, the originally designed [-] kilometers of pipelines may become [-] or [-] kilometers to meet the needs of the drop.

This is a reasonable increase in cost, and it is still an increase in cost through design changes.

How to make money doing engineering?Just to find a way to increase the budget.Especially increase the budget on those high-margin sub-items.

"Understood, Mr. Yu! After calculating the frictional resistance later, I will make a contact form and ask the supervisor to coordinate these issues!" Huang Debin is also a person who understands, and knows Yu Qingyang's intentions at a glance.

"When doing engineering, many people regard cutting corners as a magic weapon to increase the budget. I say that people who have this kind of thinking are half-hearted, and they don't know how to do engineering.

We at Huayu Investment have never advocated it, no!It is resolutely not allowed to increase profits by cutting corners!

To increase profits, it is obtained by arranging the construction sequence scientifically and rationally, improving the technological level, speeding up the progress of the project, and reducing waste.

Every project has a trick to increase profits, it just depends on whether you can find it.

Those who can be found can earn clean money comfortably, and those who can’t find it can only earn black-hearted money. They are noisy with the supervisor and the owner all day long, complaining about the strict supervision and management, and the owner is unreasonable.

It's not easy for anyone. They are all hard workers on the construction site and they all bear responsibilities. Why bother to make it difficult for the other party.

If you complain that the supervision is strict and you don't make money, it means that you have not found the right method and the technology is not good.

Just like, templates with the same price, and the same small-scale contract work, some master carpenters can earn seven to eight hundred thousand a day, while others can only earn two to three hundred.

The same is true for shaving. Some people can only shave twenty or thirty square meters a day, but they still can't test it.Some people can scrape more than 100 square meters a day, and the quality is acceptable.

This is the gap between being able to do it and not being able to do it. You can only improve if you find reasons for yourself. If you always blame the other party, you will only become a resentful woman.

This is the principle I have always adhered to, and I emphasize this in every project department! "Yu Qingyang went to the stage and delivered a passionate speech.

Every successful boss is a successful speaker, and Yu Qingyang is exercising this ability.

　Since yesterday, the word count has been secretly increased by [-]!
