The relocation is Party A's business, and the project legal person of this project should be the Nanshan District Water Conservancy Bureau, and Yu Qingyang does not want to get involved in the relocation and occupation more.

Just now, I just casually asked about the difficulties, but it doesn't mean that all difficulties will be solved for them.

Generally speaking, Yu Qingyang is still satisfied with the work of the water system connection project department.

Now the most commonly used rock pipe jacking is manual 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 the danger is high, especially the tunnel section of the connecting project is small, and the space in the tunnel is narrow, and once the danger occurs, the rescue can not be rescued.

China's tunnel technology is very mature and advanced, but how can a layman know that almost every tunnel has a memorial tunnel. According to official statistics, there will be an average of one life per 100 kilometers of tunnels, but this data is relatively conservative, and the real situation should be one life per kilometer.

Laymen are proud of China's infrastructure strength, but how do laymen know that our technology is built with human lives.

The mountain tunnel connection of the water system connection project can naturally also use manual excavation pipe jacking, but the project department did not stick to the rules and used the most common and low-cost artificial pipe jacking, but chose a more advanced micro tunnel machine and mechanical tunneling.

This can not only greatly improve the progress of the project, but also ensure greater safety, and most importantly, 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 mildly, if there is a safety accident, it is a trivial matter to lose some money, and 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 about him, but a stain is a stain.

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

Some people laugh that the construction unit is the father, the supervision unit is the grandmother, the design is the grandfather, and the construction unit is the son.

The construction unit is difficult!

Anyone can scratch you!

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

There's no way, the people below are howling at you, and you can only listen, who told you not to pay?

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

No, the money is all from the owner's father, he doesn't send money, where will the construction unit send the money?

The construction unit does not print money, advances in the early stage, and can't always advance funds later?

No one's money is blown by the wind, and no one can carry dry food to work.

Facts have proven that those contract foremen who work with dry food on their backs die miserably in the end.

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

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

This is like a municipal road, the construction unit with the third-level qualification can do it, such municipal roads are often financial allocations, but when the project is started, the financial mother who manages the money has only 30% of the project funds, and even a penny of the budget is not altogether, just because of the requirements of the superiors, and it is hard to do it.

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

Do you do it or not?

There are hundreds of construction companies waiting in line.

You have to bite the bullet!

However, if you replace it with a cross-sea bridge, it will definitely be in strict accordance with laws and regulations, before the start of the project, if the construction period is more than one year, at least 30 percent of the construction funds will be transferred to the special account, and if the project is less than one year, at least 50 percent of the funds will be transferred to the special account.

And the follow-up funding sources also have a clear source and arrival time.

Basically, the construction unit can really do such a project, and the two parties to the contract are on an equal footing.

To paraphrase the concept of family, it is those low-tech projects, just like in the past sixties and seventies, there are many construction sons, and more is not expensive.

If you dare to stab, you will be beaten when you should be beaten, you will be scolded, and even if you don't stab, you still want to give you away!

The high-tech engineering project is a family in the nineties, and the construction sons are all only children, and the children are naturally expensive.

Occasionally, grandparents, parents will also pet and coax.

I am afraid that if you skip meals, it will affect your physical development, affect your studies, and so on.

"The distance of the pipeline is as long as 15.2 kilometers, I just took a look at the drawings, the water level elevation of the Wolongshan Reservoir is 124, and the elevation of the Xingquan River at the end is 145, and the height difference between the two is 21 meters.

"The two water pumping stations are vertical pipeline centrifugal pumps, with a flow rate of 100m3/h, a head of 50m, and a maximum power of 30KW, which should be able to meet the design needs!" Huang Debin glanced down at the drawings before he spoke. 33 starters

"Don't be superstitious about the design institute, you have to have your own opinions, the length of the pipeline is 15.2 kilometers, its friction resistance, and I just looked at it, there are a lot of elbows, and the elbow resistance is not small, you have to calculate by yourself, the power of the two water pumping stations, that is, the two vertical centrifugal pumps, minus the resistance, how much can be left? Can the design head meet the pressure of the pipeline's water lifting demand?" Yu Qingyang reminded with a smile.

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

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

"Knowing Mr. Yu, I will calculate it when I go back, and if it fails to meet the design requirements, I will make a report and ask the design to be changed to increase the power of the centrifugal pump!" Huang Debin did not argue, nodded and agreed.

"In fact, in addition to increasing the power of the centrifugal pump, there is also a way, that 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 flow itself to transport it over long distances!" "33 update fastest Mobile:://

This is actually very easy to understand, which 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 can flow by its own pressure in the pipe.

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

Instead of going uphill all the way up slowly, the friction of the pipeline and the resistance of the elbow are added layer by layer, and finally the head of the centrifugal pump is consumed.

Of course, Yu Qingyang's suggestion is not without shortcomings, that is, the original design of a 15.2-kilometer pipeline to meet the needs of the drop may become 17 or 8 kilometers.

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

How do you make money doing projects? You have to find a way to increase your budget. Especially increase the budget on those high-margin sub-items.

Many people regard cutting corners as a magic weapon to increase their budget, but in fact, they are construction workers with half a bottle of vinegar.

As far as water conservancy projects are concerned, the increase in profits is obtained through reasonable adjustment of construction technology and reasonable and legal adjustment of the engineering quantity of each sub-project.

Construction projects are obtained by scientifically and reasonably arranging the construction sequence, improving the level of technology, speeding up the progress of the project, and reducing waste.

Every project has a trick to increasing profits, it's just up to you to find it.

People who can be found can make clean money comfortably, and those who can't be found can only make black money, noisy with the supervisor and the owner all day long, complaining about the strict supervision and management, and the owner is not humane.

It's not easy for anyone, they are all hard workers on the construction site, and they all bear responsibilities, so why bother to embarrass each other.

You complain that the supervision is strict and you don't make money, that is because you didn't find the right way, and the technology is not good.

Like, with the same price template, the same small section of contract labor, some carpentry masters can earn seven or eight hundred or thousands a day, and some can only earn two or three hundred.

The same is to scrape the white, some people can only scrape twenty or thirty square meters a day, and they can't check it. Someone can scrape more than 100 square meters a day, and the quality is qualified.

This is the difference between what you can do and what you can't do, you can only make progress by finding reasons for yourself, and always complaining about each other will only become a resentful woman. 33 starters

"It's next year, Mr. Yu! I went back and calculated the friction resistance, so I called the contact list and asked the supervisor to coordinate these problems!" Huang Debin also understands people, and he knows Yu Qingyang's intentions.
