Is the weir made of mortar stone or reinforced concrete?

The stress indices of the two structures are different.

If mortar is used to lay stone, then the retaining wall needs to be thicker and taller to meet the design requirements.

If reinforced concrete is used, it needs to be thicker and taller to meet the design requirements.

Yu Qingyang walked to the desk with the drawings and spread them out.

“According to our on-site survey, flash floods form in this valley every rainy season!

Therefore, we added twenty gravity weirs in the middle of the river to reduce the impact of flash floods!" Dean Fei stood behind Yu Qingyang and explained to him.

Gravity-type water dams not only store water but also block water.

The reason why flash floods are so harmful is that they are often mixed with sand and gravel.

The impact of the water flow, coupled with the rushing force of sand and gravel, brings destructive power that is not as simple as one plus one equals two.

Twenty water blocking weirs intercept the sand and gravel through layers of interception.

"Yeah!" Yu Qingyang nodded and continued reading.

“We have also carried out risk-relieving and reinforcement designs for the mountains on both sides!

The main thing is to carry out anchor shotcrete reinforcement!”

"Yes!" Yu Qingyang nodded with satisfaction.

Anchor shotcrete reinforcement is a very profitable construction project.

There should be more similar projects.

"Here at the source, considering that this is a barrier lake, the naturally formed dam is not stable enough. Once a mountain moves, an earthquake or a volcanic eruption occurs, there will be geological disasters!

The hegemonic body may collapse, causing devastating damage to the oil town outside the mountain!

Therefore, we added a more stable water-blocking dam outside the natural dam!

There are flood gates and water outlets on the dam body!

The original natural dam body will be blasted after the new dam is repaired!"

“Won’t blasting cause damage to the new dam body?

Also, there are a lot of aquatic life in the lake!

Will blasting cause massive death to aquatic life?

By then, those environmental organizations will protest..." Yu Qingyang reminded with a smile.

"I have consulted blasting experts and chemical silent blasting can be used.

The main raw material for chemical silent blasting is ordinary quicklime.

When quicklime reacts with water, the volume will expand rapidly and a pressure of up to 29.4 MPa can be generated, which is enough to statically break cement components, rocks, etc.

Therefore, there will be no rushing waves, no disturbance to the new dam body, and no impact on the creatures in the lake!"

"That's okay!" Yu Qingyang nodded.

"Hydropower station, consider building it at this location!

It is relatively close to the oil town, and the terrain is relatively open!

It’s suitable to build a dam to regulate the flow rate!”

This is the first high platform that Yu Qingyang and others passed when entering the mountain.

In the rainy season, a natural waterfall will form here.

"Okay! Your progress is very fast!

I think the only thing missing now is the artificial lake, the flood discharge channel downstream of the artificial lake, and the diversion channel!

The day after tomorrow, I will take you all to the Geographic Glass for a cool tour. When I come back, I will work harder and seize the time to get the construction drawings out!"

"Thank you, Mr. Yu! Don't worry! We will definitely work overtime to produce the construction drawings!" Dean Fei assured, patting his chest.

…

"You took Qiao Lili to the Geographic Glass. You are a man and a woman alone. Tell me honestly. Did you eat anything secretly?" At night, Xia Xue lay in Yu Qingyang's arms and asked in a low voice.

"Eating on the sly? Am I that kind of person?

Never heard that rabbits don’t eat grass near their nests?

I didn’t even eat it despite a beautiful woman like you!" Yu Qingyang smiled and reached out to pinch Xia Xue's face.

"You deserve it. It's not like I won't let you eat. Who do you blame if you don't eat?"

"'..."

Yu Qingyang didn't know how to answer the question, so he could only laugh and say nothing.

Ever since Xia Xue confessed her love to Yu Qingyang, the two of them acted more and more casually.

Of course, the main reason was that Xia Xue became more and more casual with him and often got tired of Yu Qingyang.

This made Yu Qingyang very angry.

If he hadn't considered that eating Xia Xue would be too troublesome, Yu Qingyang would have eaten her dry.

Although Xia Xue said she didn't care about his relationship with Tian Tian, ​​who knows if it was impulsive.

Women and men are actually very petty, and no one is willing to share their love with others.

Officially because he couldn't figure out Xia Xue's true thoughts, although Yu Qingyang was irritated by Xia Xue's teasing, he still held it back.

Fortunately, he learned Zhou Botong's secret skill in his previous life, the left-right fighting technique.

It can relieve the anger a little bit.

Otherwise, he would have been burned with desire and died long ago.

"How about I... help you with my hands?" Xia Xue whispered with a blushing face.

"No need, I have my own hands!" Yu Qingyang simply shook his head.

"What are you afraid of? I'm not afraid of any girl, so what are you afraid of?

Or not a man?" Xia Xue pushed Yu Qingyang down on the bed...

"hiss……"

Yu Qingyang took a deep breath.

...Fifty thousand words are omitted here...

The next day, Yu Qingyang left the room refreshed.

"Comrades, it has been almost two months since I came to Ajigeria!

It's hard here, but everyone is doing great!

Don’t be scared by difficulties!

We have overcome one difficulty after another with our ingenuity!" Yu Qingyang stood under the flagpole and said loudly.

As long as Yu Qingyang was in the camp, he would hold a morning meeting for everyone every day, lead everyone in singing patriotic songs, and drink some chicken soup.

Then he led everyone to run and exercise.

"For whom! Sing together!

Mud covered trouser legs

Sweat soaked through the back of clothes

i don't know who you are

But I know who you are for

for whom

…

Who is the most beautiful

Who is the most tired

My fellow countrymen, my comrades-in-arms

My brothers and sisters…”

This is a military song, but Yu Qingyang feels that it is more of a song written for engineers like them.

Mud covered his trouser legs, and the back of his clothes was soaked with sweat.

Isn’t that what they engineering people are like?

All year round, five winters and six summers, we wear work clothes.

Buy good clothes, wear them only a few times a year, and keep them in the closet until your body loses shape and the clothes no longer fit, but they are still new.
