After He Ying was tied with one hand, she stopped struggling.

This is the end of the battle.

"You didn't draw your sword, so it's a draw."

"I can afford to lose."

The two of them each said politely, Chen Duan withdrew the weapon, He Ying rubbed his wrist, the two failures were surprisingly similar.

She could see that Chen Dui's physical fitness was still at the level of ordinary people, but his use of abilities was indeed much higher than hers.

He Ying is still a strong person in his bones, and losing does not mean that he is convinced, obviously this guy's ability should be an assistant!

But she also knew that unless she quickly outpaced her opponents in terms of abilities, the gap would only grow.

Dong Junwei smiled: "You are so interested? Early morning exercise? ”

"I happened to meet it, so I played with both hands."

"Actually, it's not bad, actual combat is the best way to train people."

"That's what I thought, too."

“……”

When everyone saw that there was no more excitement to watch, they all dispersed.

……

After breakfast, everyone threw themselves back into the huge water diversion project.

After the reservoir was completed, the next most ambitious task was to make the pipes.

The pipeline itself is not very difficult for Chen Du, but when the number is large to a certain extent, it is not an easy job.

"The difficulty of the pipe itself is not high, it's just cumbersome, but the bracket is a problem, how high should the water connection of the storm pipe be set?"

"About 30 centimeters is fine, this pipe is an auxiliary pipe, usually self-draining, only when we need to fill the water tank, will open the water outlet on it."

Tang Jing spoke, stretched out his hand to the height, and said, "The problem of the bracket is okay, because no matter what, we have to make a hole in the door, and it will be a natural pipe rack when the time comes." ”

"What is the height of the opening in the door?"

"About 25 centimeters, the slope of the initial section of the water pipe does not need to be too large, it is best to be perpendicular to the rainwater pipe, which can also prevent large particles of impurities from flowing in with the water to the greatest extent, but after passing through the door, you need to make a 90-degree elbow, and the quality of the elbow must be excellent, because the impact force of this place will be the largest."

"And then take a riser, go down to the ground, and then drain through the crack in the door?"

"Yes, you seem to understand what I mean." Tang Jing said with a smile.

"Not as professional as you, but I understand it generally." Chen Du smiled: "I actually thought at first, can we connect a water pipe directly from a certain water source, such as the water dispenser in the classroom, the bucket on it, if it is full, it can let us use it for a long time." ”

"There's enough water, but it's not practical."

"Because the project is too big?"

"The enormity of the project is one thing." Tang Jing cast his gaze in the direction of the teaching building and continued: "Even if you can make such a pipe, it is impossible to take it. ”

"Why?"

"If the pipe is too thick, the water in the water dispenser has not yet filled the pipe, there is no more, which is obviously meaningless, but if the pipe is too thin, it is also not good, because the diameter of the pipe is small to a certain extent, and the water flow is difficult to flow on its own, which involves the surface tension of the water and the problem of atmospheric pressure, in addition, the smaller the pipe diameter, the greater the head loss along the way, and when the time comes, the water will flow halfway, and it will not move."

"Along the way...... What? ”

"Head loss, which is a term used in the plumbing profession, roughly means the resistance of water in the pipes, so this can be another counterintuitive place, not to mention that pipes laid outdoors are likely to be damaged."

"Okay."

At this time, the surrounding people had fallen into petrification, and they didn't listen to the conversation between the two at all.

After the construction officially began, everyone stopped thinking about it.

Tang Jing arranged everyone's own work, and even herself and the girls were assigned some physical work that was not too heavy.

Chen Dui's first thing.

It is to make a hole about 1 cm in diameter at a height of 25 centimeters on the door.

This pipe diameter was also determined by Tang Jing after weighing the workload and Chen Duan's ability.

Twenty or thirty centimeters in height.

There was really no big problem with Chen Du at this time, he casually made the handle and climbed up at the same time.

However, it takes a lot of effort to make a 1 cm diameter hole in the top of the 4.5 cm thick wooden door.

Meanwhile.

The people below are also in full swing carrying various materials.

Because it was wood, the density was not very high, and it took Chen Du about half an hour to finish.

There were also two breaks in between.

He then did the same, climbing onto the storm pipe.

The plastic PVC pipe of DE50 has a wall thickness of 4.5mm, which is even less difficult than a wooden door.

……

The key to determining the completion time of the entire project is still on Chen Dui.

The rest of the work is to make pipes, docks, and smooth and fill gaps in the gaps, in addition, the sedimentation tank and grille that Tang Jing said, these two things are relatively simple.

The so-called sedimentation tank is a plastic box with a higher height than the water tank, but the base area is small and long.

After the water is filled inside, it flows for a distance and then leaks from the high outlet into the tank, and it is all pre-settled water, although it is still not very clean, but it is enough for bathing or something.

After all, after the elimination of industrial and vehicle exhaust fumes, the sulfide in the rainwater is also much reduced, and in a few weeks, the water quality will be even better.

The most time-consuming is the manufacturing pipeline.

Although Chen Du no longer strives for the roundness of the pipe, there is still not much production on the first day.

No matter when he is at any time, he will not consume too much mental energy, even when he is at home, he will stop when he feels a third of the time left, the reason is of course to deal with emergencies.

Of course, the amount of mental power is difficult to quantify, and it is only based on feelings every time.

……

The first day was a fruitful one.

According to Tang Jing's prediction, in about six days, their water diversion project will be completely completed, and after that, as long as it does not rain for more than a month, there will be a steady stream of domestic water, and even He Ying no longer needs to get up in the morning to look for dew outside to wash his face.

Fortunately, the market is located on the southeast coast, and there is plenty of rainfall, so at least in the summer, there is no need to worry about not raining.

By the time of the afternoon break.

Tang Jing gathered everyone together.

"I have roughly drawn up the rules and regulations of the Qiming Organization and the powers and responsibilities of positions at all levels, so let's vote on it."

She promised yesterday that she would come up with a charter within 24 hours.

"Do you want to write it down?" Du Jiajia asked.

"Yes."

Tang Jing smiled: "But it's not in a hurry, after everyone listens to it and thinks there is no problem, then frame it." ”
