Chapter 464 The gap between what can do and can't do it (seeking the moon
Relocation is a matter of Party A. The legal person of this project should be the Nanshan District Water Conservancy Bureau. Yu Qingyang does not want to get involved in the relocation matter.
Just now I just asked about the difficulties casually, but that does not mean that I will solve all the difficulties for them.
Generally speaking, Yu Qingyang is satisfied with the work of the Water System Connection Project Department.
Nowadays, the most commonly used rock pipe jacking is artificial pipe jacking. The rock on the excavation surface is blasted, the debris is manually cleaned, trimmed, and then jacked in!
The cost of this method is relatively low, but the disadvantage is that it is highly dangerous, especially since the tunnel section of the connecting project is small and the space inside the tunnel is narrow. Once danger occurs, rescue will not be possible.
China's tunnel technology is very mature and advanced, but how would a layman know that almost every tunnel has a human life? According to official statistics, on average there is one life for every 100 kilometers of tunnels. In fact, this data
Relatively conservative, the real situation should be one life per kilometer.
laymen are proud of China's infrastructure strength, but how do they know that our technology is built with human lives?
Naturally, manual tunneling and pipe jacking can be used to connect the mountain tunnels of the water system connection project. However, the project department did not stick to the rules and use the most common and lowest-cost manual pipe jacking. Instead, they 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. 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 a safety accident occurs, it is a small matter to pay some money. The safety accident will become a stain on the company and on Yu Qingyang's life. This cannot be washed away.
Maybe no one can do anything to him, but a stain is a stain.
The second is the improvement of technology and construction level, and the innovation of technical processes. 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 various units involved in project construction, the construction unit is at the bottom. Some people jokingly call the construction unit the father, the supervision unit the grandma, the designer the grandpa, and the construction unit the son.
It’s difficult for the construction unit!
Anyone can give you a few pricks!
Sometimes, even the construction team below dares to howl at you!
You have no choice but to listen to the people below yelling at you. Who told you not to pay?
However, does the construction unit have the final say on whether to pay or not?
No, the money is all with the owner’s father. If he doesn’t pay, how will the construction unit get the money to distribute it to the downstream?
The construction unit does not print money either. It advances funds in the early stage, but cannot always advance funds later?
No one's money comes from the strong wind, and no one can carry dry food to work.
Facts have proven that those contractors who worked with rations on their backs died miserably in the end.
Therefore, if construction units want to live a better life, they can only strive to reach the top and strive to improve their own quality and conditions.
Facts have also proven that the larger the project and the higher the technological content, the greater the say of the construction unit.
This is like a municipal road, which can only be built by a construction unit with third-level qualifications. Such municipal roads are often financed by financial allocations. However, when the project is started, the financial mother in charge of the money only has 30% of the project funds, or even simply
I didn’t have a penny of budget, I just went ahead because my superiors asked me to do it.
Therefore, the owner requires the construction unit to advance funds for the work, or delays the audit payment.
Do you want to do it or not?
Don’t want to do it? There are hundreds of construction companies waiting in line behind you.
You just have to bite the bullet and do it!
However, if you switch to a cross-sea bridge, you will definitely strictly follow the laws and regulations. Before the project starts, if the construction period is more than one year, at least 30% of the construction funds will be transferred to the special account. If it is less than one year, at least 30% of the construction funds will be transferred to the special account.
Fifty percent of the funds go to a dedicated account.
And the subsequent sources of funds also have clear sources and arrival time points.
Basically, only the construction unit can truly implement such a project. As the book says, both parties to the contract are on equal footing.
Applying the concept of family, it means those projects with low technical content, just like in the past 1960s and 1970s, when there were many construction sons, the money was not valuable.
If you dare to prick you, you will be beaten when you need to, and you will be scolded when you need to be scolded. Even if you don’t prick you, I still want to give you away!
As for engineering projects with high technological content, it was a family in the 1990s. The construction sons were all only children, so having fewer children naturally meant more money.
Occasionally, my grandparents, parents, and parents will pamper and coax me.
I'm afraid that if you don't eat, it will affect your physical development, your learning, etc.
"The distance connected by the pipeline is 15.2 kilometers. I just took a look at the drawings. The water level of Wolongshan Reservoir is 124, while the elevation of Xingquan River at the end is 145. The height difference between the two is 21 meters.
Have you calculated whether the two water pumping stations can meet the designed pipeline pressure?" Yu Qingyang flipped through the drawings and looked up and asked.
"The two water pumping stations use vertical pipeline centrifugal pumps with a flow rate of 100m3/H, a lift of 50m, and a maximum power of 30KW. They should be able to meet the design needs!" Huang Debin looked down at the drawings before speaking.
"Don't be superstitious about design institutes. You must have your own opinions. The friction resistance of a pipeline with a length of 15.2 kilometers, and I just took a look. There are many elbows, and the resistance of the elbows is not small. You
You have to calculate it yourself. How much power is left after subtracting the resistance of the two water lifting pump stations, that is, the power of the two vertical centrifugal pumps? Can the designed head meet the pressure of the pipeline water lifting demand?" Yu Qingyang reminded with a smile.
One sentence.
Of course, even if in the end, the designed lift fails to meet actual needs, it is not the fault of the construction unit, but it is always troublesome.
But looking at the design parameters, the two vertical centrifugal pumps have a total lift of 100m and a total power of 60KW. There seems to be no problem. However, although Yu Qingyang did not calculate it carefully and just based on past experience, it felt a little unreliable.
"Now that I know Mr. Yu, I will go back and calculate it. If the design requirements are not met, I will file a report and ask for design changes to increase the power of the centrifugal pump!" Huang Debin did not argue and nodded in agreement.
"In fact, in addition to increasing the power of the centrifugal pump, there is another way, which is to maximize the effective use of the lift of the centrifugal pump, lift the water to the top of the mountain, and then use the pressure of the water flow to transport it over long distances!"
This is actually easy to understand. It uses a centrifugal pump to lift the water to the nearest hilltop, and then all the way down, allowing the water to flow by its own pressure in the pipe.
Lift the water to the nearest hilltop, the transportation distance is short, there are few elbows, and the effective utilization rate of the centrifugal pump's head is high.
Instead of slowly going uphill all the way like now, the friction of the pipes and the resistance of the elbows increase layer by layer, eventually consuming all the head of the centrifugal pump.
Of course, Yu Qingyang's suggestion is not without its shortcomings, that is, the originally designed pipeline of 15.2 kilometers may become 17 or 18 kilometers to meet the needs of the height difference.
This is a reasonable increase in cost, and it is also an increase in cost through design changes.
How to make money doing engineering? You need to find ways to increase the budget. Especially increase the budget for those sub-items with high profits.
Many people regard cutting corners and materials as a magic weapon to increase the budget. In fact, those who do this are half-hearted construction workers.
Increased profits are never obtained by cutting corners and cutting materials. As far as water conservancy projects are concerned, increased profits are obtained by reasonably adjusting the construction technology and adjusting the work quantities of each sub-project reasonably and legally.
Construction projects are achieved by scientifically and rationally arranging construction sequences, improving craftsmanship, accelerating project progress, and reducing waste.
Every type of project has tips for increasing profits, it just depends on whether you can find them or not.
Those who can find them can make clean money comfortably, but those who can't find them can only make dirty money. They argue with the supervisors and owners all day long, complaining about the strict supervision and the unreasonable owners.
It’s not easy for anyone. We are all hard workers on the construction site and we all bear responsibilities. Why bother to make things difficult for the other party?
If you complain that supervision is too strict and you are not making money, it is because you have not found the right method and your technology is not good enough.
Just like, with the same price template and the same small-section contract work, some carpenters can earn seven to eight hundred or thousands a day, while some can only earn two to three hundred.
The same is true for shaving Dabai. Some people can only shave 20 to 30 square meters a day, but they still can't test it. Some people can shave more than 100 square meters a day, and the quality is acceptable.
This is the difference between those who can do something and those who can't. Only by looking for reasons within yourself can you make progress. If you always blame the other person, you will only become a resentful woman.
"It's next year, Mr. Yu! I'll go back and calculate the friction, and then I'll make a contact sheet and ask the supervisor to coordinate these issues!" Huang Debin is also a sensible person, and he knows Yu Qingyang's intentions at once.
