"Zhuge Changshi, do you see the mystery?" Cui Yu said with a look of surprise.

First, drive a few large wooden piles, open the slots in advance, and then connect them with wooden boards, what is this for, use wooden piles to make bridge piers, and surround them with wooden boards, so that people can't see that they are empty inside?

The more Cui Yu looked at it, the more confused he became, but Zheng Peng was directing the work, and he couldn't find anyone to ask, so when he heard Zhuge Zhi's words, he immediately asked.

As soon as the words fell, many people looked at Zhuge Zhi, and those who stood close either pricked up their ears or slowly approached them, all wanting to listen to Zhuge Zhi's analysis.

Zhuge Zhi couldn't refute Cui Yu's face, and said knowingly: "General Zheng's approach is very simple and very smart, as long as everyone listens to a certain story, they will soon understand." ”

Coughing dryly, Zhuge Zhi continued: "About five years ago, I went to a village near Taiyuan to visit a friend, but I didn't expect heavy rain from the sky, the flood broke the river embankment, my friend's village was flooded, most of the houses in the village were flooded nearly five feet high, and the flood was going to rise. ”

"The whole village was flooded, the flood washed away the furniture, clothes and so on, and a certain was surprised to find that there was only one house in the whole village that was not flooded, and the house that was not flooded, the water outside was more than five feet high, but there was no water in the house at all, the reason was very simple, except that this house had a strong wall to block it, and the door was also specially designed."

"There are card slots on both sides of the wall at the door, you can stuff wooden boards into the card slots, one layer inside and one layer outside, and the middle of the two layers of boards is empty, so that the empty position is filled with soil and compacted to form a wall that does not permeable, so that the flood cannot enter, and the home will not be affected."

After saying so much, Zhuge Zhi took a breath slightly, and quickly continued: "Cui Lao, look, the location of General Zheng's eight piles, look at the planks that are pressed down from the stake trunking, it is obvious that he wants to enclose a large square, a small square, when he uses wooden planks to enclose it, a closed space is formed between the large and small squares, in short, it is like a [hui] character, the gap between the big mouth and the small mouth is filled with soil, like ramming the city wall, you can prevent the water from coming in, and then use a bucket to scoop out the water inside, In this way, the bridge piers can be repaired in the river. ”

It turned out that this was the case, Cui Yu suddenly realized, but he quickly said suspiciously: "Even if the surrounding water is blocked, if you dig it down, it will seep water." ”

Zhuge Zhi explained: "As long as the seepage is not cleared quickly, it can be constructed, which is equivalent to digging a well with more water, that is, it is seepage, it can also be dug deeper, and it is easy to do things with many people, I believe that General Zheng has already had a countermeasure to these unexpected problems, of course, these are just some speculations, whether it is or not, it remains to be seen carefully." ”

Cui Yu said with admiration: "Zhuge Changshi is really well-informed, and the little old man admires it." ”

The carpenter was very efficient, adding boards to the two squares at the same time, and at this time, the space that Zhuge Zhi said could be filled with soil had appeared.

I have to say that this method is so wonderful, even Cui Yu is also amazed.

Zhuge Zhi is an example and an explanation, which is easy to understand, not only Cui Yu, but also many people next to him nodded again and again, shouting brilliantly.

Zheng Peng did not disappoint Zhuge and almost followed his train of thought, first asking people to use wooden planks to pass through the slots to enclose the eight wooden stakes first, enclosing two squares, one large and one small, forming a closed space between the two squares.

Don't look at just pressing the wooden board down to the trunking, because it is waterproof, it must be pressed very densely, and the concave and convex grooves of the board and the board must also fit completely, and dozens of people have worked hard for a long time to complete.

After completion, Zheng Peng did not rest, but kept asking people to fill in the middle of the two squares.

The soil is not ordinary loess, but the glutinous rice juice carefully stirred the cement, this mud is sticky, not easy to disperse, but also easy to solidify, as the cement continues to fill, the closed space formed between the two layers of wooden boards continues to overflow, at the beginning it was full of water, with more and more cement, less and less water, about half an hour later, the enclosed space has been full of cement.

At this time, the masons took action, and kept adding soil and glutinous rice juice to it, and kept tamping it like ramming a wall, and at the same time, large wooden barrels were thrown into the small pond that was fenced in, and began to clean the river inside.

After a while, half of the water inside was cleared.

"Wonderful, this method is really amazing." Cui Yu stared at his old eyes and said excitedly.

I don't know how the bridge pier was built in the end, but Zheng Peng's whimsy conquered Cui Yu.

It doesn't seem difficult, and the operability is also very large, as long as this method is used, many people can do it, but the problem is that only Zheng Peng thinks of it and applies it to building bridges.

Zhuge Zhi shook his head and said with admiration: "It's really a hero out of a young man, General Zheng can use a pile of wood to build a bicycle, can transform Kong Ming lanterns into hot air balloons, I know that he is very smart, and now I see General Zheng skillfully build bridge piers, so, I am served." ”

"Elder Cui, you have found a good son-in-law." Zhuge Zhi added.

"Hahaha, although the third child has a cold temperament, his eyes are still good." Cui Yule said hehehe.

In the crowd, Lu Shu said with a smile: "Sister Hong, Sister Hong, have you seen it, the young master is really smart to build the bridge pier in this way, right?" ”

"Yes, this method is simply absolute, the slave family has already said that he believes in Zheng Gongzi, and he must have a way to deal with it."

Saying this, the cardinal secretly said in his heart: I believe in your evil, this Zheng Peng is really evil, it seems that anything difficult is not a problem for him anywhere, I remember the first time I saw him in your hometown, he was just a small person who could be ignored, but I didn't expect that in just a few years, he was a general and a knighthood, and he was a little fly and woke up a sleeping tiger?

Not only were the cardinals surprised, but the crowd of onlookers was also conquered by Zheng Peng's whimsy, and it was noon, and the sun was shining, but people had no intention of dispersing, but people gathered more and more, stretching their necks one by one, opening their eyes wide, and watching with great interest while talking.

"Young master, the waterproof wall is enclosed, and the water inside is almost clear, but it is still seeping." Lao Qi wiped the sweat on his forehead while reporting to Zheng Peng. ”

"Check it out."

Zheng Peng walked under the shelf and looked down from above, only to see that there was a layer of water about half a foot high inside, and two healthy servants jumped inside to help the people outside clear the water.

Underneath the water, there is a deep layer of silt.

It's not bad, to achieve the expected effect, Zheng Peng nodded secretly, and quickly said: "Water seepage is normal, send someone to clear it in time, as long as the seepage is not cleared quickly, our goal will be achieved, now immediately send someone in to dig down for me, dig according to the size set in front, the speed of digging must be fast, so let's change people once in a quarter of an hour." ”

"Young master, how deep do you have to dig?"

"At least dig into the hard soil layer, and preferably not at all." Zheng Peng said categorically.
