"Mr. Yu, the clouds in front are too thick, and the rain is very heavy, and it will be dangerous to continue to fly forward!

Is it a return home?" the helicopter pilot shouted.

"Homecoming!"

Without the driver's instructions, Yu Qingyang is also ready to return.

Dark clouds were gathering not far ahead, and the white expanse below the helicopter was full of fog.

There was a thunderous sound of water under the fog, all of which indicated that there was heavy rain in the mountains ahead, even torrential rain, which had formed a flash flood.

"See? Don't use the weather forecast outside the mountains to cover the weather in the mountains!

The climate change in the mountains is very big and unpredictable!

The weather forecast outside the mountains is not accurate, let alone inside the mountains.

Danger is always there when you don't expect it!

If you pay attention to the accident statistics released by the state, you will find that the fatality rate of falling from low altitude is much higher than that of high altitude!

Do you know why?" On the way back, Yu Qingyang took the opportunity to give them safety education.

"Because everyone knows the danger at high altitude, the protection is well done!" Zhang Zexian was still in a state of downtime, and Huang Wenyun replied for him.

"Yes, we all know the dangers of high altitudes, so I don't need to explain much, and I will consciously do a good job of protection!

After all, no one's life is picked up!

But the problem is that danger often comes from places that you all think are safe.

Let me give you two examples.

My dad is an engineer, commonly known as a contractor, and he does everything.

From road repairs to building buildings and building roads!

Among them, the most dangerous thing is to build a building and paste a mosaic on the exterior wall!

At an altitude of tens of meters, two ropes, a wooden plank, and two plastic buckets are hung on the wooden board, and people sit on the wooden plank and paste mosaics at an altitude of dozens of meters.

However, my dad has been working in engineering for more than 20 years, and he has never had an accident with the high-altitude work on the exterior wall!

On the contrary, when we changed the asbestos tiles on the bicycle shed for our Quanshui City Water Conservancy Bureau, two fell to death and one died!

The bicycle shed, which is just over two meters high, will be fine if you jump directly from it?

But at such a high distance, people fell to their deaths!

Also, when my dad was working on the rainwater pipes, the five hundred rainwater pipes and the pipe ditch were more than two meters deep!

Workers working at the bottom of the ditch shouldn't be dangerous, right?

Even if the pipe ditch collapses, this bit of soil will not kill people.

However, when a worker lowered his head and was rubbing the pipe belt at the bottom of the ditch, a stone fell from the top and hit the brain stem.

At that time, I picked up a bag, and as soon as the person got on the road, it didn't work!

Therefore, you can let go of technology and construction technology, boldly innovate and try boldly.

But safety, as conservative as you can, as conservative as you can!"

"Mr. Yu is right, accidents often happen by accident and coincidence, and they can never be avoided, so we can only find ways to reduce the probability of occurrence!

I reviewed, the construction plan was too rough, and there was no detailed investigation of the construction environment!

Without doing a field trip, he closed his door and almost caused a catastrophe!" Huang Wenyun bowed his head and reviewed.

Yu Qingyang shook his head with a smile and did not speak.

No one was criticized either.

Now, there is no need to criticize, and they know that they are afraid.

The helicopter landed in a clearing next to the valley.

At this time, just in time, the flash flood also rushed out of the valley.

After nearly half a year of quarrying, the section of the valley entrance has expanded several times, and the river is much smoother than before.

The flood that rushed out did not have the momentum of pouring thousands of miles in the deep mountains, but it was still fierce.

Soon the big pit that had just been dug was flooded.

Workers, machine operators, stood on the hillside, watching the rushing flood water in a daze.

Fortunately, Yu Qingyang's notice was timely, and the mechanical operators were all veterans with good obedience, and all the machinery and equipment were evacuated to the high ground.

There was no damage to property, people.

This is a blessing in misfortune.

Return to the base and reorganize the construction plan.

"According to the original construction plan, although in terms of cost control, it is more advantageous!

However, there are great security risks!

Who can guarantee that today's flash floods will not erupt again?

The huge body of water in the mountain is a dammed lake, and we water conservancy people know the hidden dangers of dammed lakes!

It can be said that it is a bomb hanging over the head!

Once an earthquake or crustal movement causes the dam of the dammed lake to collapse, not to mention the personnel and machinery in the valley, even if it is an oil town more than ten kilometers away, it will all be submerged!" Yu Qingyang directly took over and presided over the construction plan seminar.

Yu Qingyang said as he drew the topography of the valley and the location of the dammed lake on the whiteboard in the conference room.

"So, our first step, what we have to do, is to add a dam downstream of the dammed lake!

It's difficult, but the dam is our lifeline!

It's equivalent to dismantling the fuse of the bomb overhead!" Yu Qingyang used a red marker pen to draw a horizontal line under the dammed lake.

The dam can not only be used as a protective umbrella for downstream construction workers.

The dam is an essential building for every hydropower plant.

You can learn about Gezhouba, Baihetan Hydropower Station, and Xiangjiaba Hydropower Station.

The ancestors said that water is impermanent, that is, the flow of water is changeable, and there is no fixed form.

The velocity and flow rate of water are constantly changing.

This is unpredictable and clearly unsuitable for power generation.

So there is the first dam, which has the function of both holding water and diversion, through the diversion gate, so that the water flow according to the required flow rate and flow into the water conveyance structure of the turbine.

Of course, there is also a very important structure of the dam, which is the flood gate, or Yihongdao, which is used to drain excess water.

Some rivers with traffic requirements should also be equipped with locks to facilitate the passage of passing ships.

"Mr. Yu, there is a problem, the dammed lake is deep in the mountains, and raw materials such as cement and sand cannot be transported in!

If you build a road into the mountain, the cost is too high!

In addition, the life of the workers in the mountains is also a problem!" Huang Wenyun stood up and offered his opinion.

"The question you raised does exist, the first is how to transport raw materials in, and the second is how the workers live in the mountains!

If you are in China, I would recommend that you install a ropeway to transport raw materials and concrete up the mountain.

But, in Africa, no!

There's a lot of cheap labor out there that you can't imagine!

Clear a mountain path along the ridge next to the valley and ask the locals to carry the raw materials into the mountains!

Dozens of miles of mountain roads, there is no problem in running two round-trips a day!

Carry a bag of cement into the mountain, give 500 dirhams, and send a bucket of water when you go down the mountain, there must be a lot of people willing to do it!"

In the currency of Ajigeria, one dinar is equal to one thousand dirhams, one dinar is equal to three and a half yuan, and five hundred dirhams is equal to one piece of seven cents and five yuan.

Transporting 10,000 tons of cement into the mountain is only 700,000 yuan.

However, the construction of a high-mountain ropeway for transporting goods for tens of kilometers cannot be won without tens of millions in China, and it will be doubled several times in Africa.

"How is that possible?" Huang Wenyun exclaimed in surprise.

He thought that the most difficult transportation of raw materials was solved so easily.

And it costs so little.

"If you go to the oil town and ask around, you will find out that the workers there are paid 500 dirhams a day!

We didn't make a single trip, we delivered a bucket of water, which was worth a few hundred dirhams outside.

Carrying a bag of cement at a time and running twice a day is equivalent to earning 2,000 dirhams!

If you carry two bags, you will earn more!

As for life, it's simpler, clean up a stone beam nearby and build a temporary base!

What kind of tent haven't you lived in?"

"That's right!" Huang Wenyun nodded and sat down, no longer speaking.

"The makeshift road doesn't need to be wide, just an excavator!

As for the oil required for the excavator, let the locals carry it in as well!

This temporary road can be transformed into a sightseeing road after the dam is repaired and the personnel and machinery are withdrawn.

Some environmental protection organizations in the province are blind!

Do you have any questions?" Yu Qingyang added before asking.

"No more!"

"Nope!"

"Since there is none, then the labor department contacts the oil town and the cement factory, and publishes the recruitment information through them!

Time waits for no one, and the excavator will immediately start to enter the mountain and open the way!" Yu Qingyang decided with a wave of his hand.

"Mr. Yu, what should I do about the reservoir area outside the mountain?" Huang Wenyun thought of the construction of the artificial lake outside.

"Leave him alone, when the rain in the mountains stops, the water outside will soon seep into the ground!

This is the Gobi, semi-sandy in nature, and it can't hold water!" Yu Qingyang said with a smile.

The water that overflows from the mountains soon seeps into the ground, enters the underground water veins, and then is carried into the mountains by mysterious natural porters, and then emerges from the springs and flows into the dammed lake.

There is also a seepage zone underneath the dammed lake, and the spring water flowing from the mountain and the seepage from the dammed lake form a perfect balance.

This is also the only time when there is heavy rain in the mountains, there will be water overflowing, forming a flash flood.

Other construction plans do not need to be adjusted, what needs to be adjusted is only a construction sequence.

At the end of the workshop, they went their separate ways.

Yu Qingyang left Zhang Zexian, who had been silent, behind.

"What's going on? I can't stand such a small blow?"

"No, Mr. Yu, it's all my mistakes, almost ......"

"Now, it's useless for you to review me!

What you have to do is not to think about who to review, but to face the problem, take the lesson, and keep it in your heart.

Then cheer up, the whole project department is looking at you!

If you, as a project manager, are frustrated and self-defeating all day long, how can you let others do their work?

Not to mention that Mount Tai collapsed in front of him and did not change color, you also have to have a certain city, you can scold your subordinates, you can also smile and face your subordinates every day, but you can't face your subordinates with your head down!

As a project manager, you don't have to be skilled, but you must be calm and able to withstand the pressure!" Yu Qingyang did not reprimand Zhang Zexian.

With such a big project on Zhang Zexian, Yu Qingyang understands how much pressure he has.

After all, he is also a person who has worked as a project manager, and I remember the first time I worked as a project manager, the amount of cigarettes directly changed from one box a day to two boxes a day is not enough.
