In fact, Huang Zu is not as stupid as Wu Dapeng imagined, and he has a strong ability to accept new things. Pen & Fun & Pavilion www.biquge.info

When he saw the usefulness of mule-style cement, he immediately devoted himself to the construction of the salt pan, full of enthusiasm.

Wu Dapeng squinted at that time with his hands behind his back and watched him sweating profusely with the miscellaneous soldiers to defend the seawall, because they were delayed for three days by a sudden spring rain and were about to be snatched back!

This kid has changed quickly, he is not a diehard, and he has not yet formed a psychological imprint......

Huang Zu's head was seen clearly when Song Ziqiang led people to repair the pressure well, it turns out that there are still such useful things in the world!

At that time, Song Ziqiang asked more than a dozen miscellaneous soldiers to dig a well on the edge of the dry field, and instructed them to mix mule and horse cement with river sand and build the well wall with bricks, and then instructed them to use mule and horse cement to smooth it.

Then he selected some bitter bamboos, cut them one by one, divided them into two kinds of bamboo and bamboo strips, and then let the half-sized ones be boiled in lime water and dried in the shade, and then soaked in wood tar to dry in the shade.

Song Ziqiang: This is preparing to use bamboo reinforcement as a material to replace the steel bars used in concrete components.

Song Ziqiang said to the half-sized children: "The bamboo tendon is tied with bamboo strips and then poured concrete, it becomes a bamboo reinforced concrete component, its bearing capacity is very good, the key is that this method is convenient and simple and saves money...... In the country, there are some unscrupulous real estate developers who use it in some places that are not load-bearing, because of the low cost of making bamboo-reinforced concrete...... So be careful when buying a house......"

“……”

And so it is.

Bamboo is known as plant steel, its tensile strength is between the first and second level of steel bars, and it does not corrode, does not deteriorate, and is rich in resources...... But after all, it is not as good as steel bar...... Of course, if it is much better than the gutter reinforcement.

Bamboo-reinforced concrete elements are strong and can partially or completely replace reinforced concrete, and were commonly used in construction in the fifties and sixties of the world.

Song Ziqiang said to the half-sized children: "The key is the treatment of bamboo tendons...... It is boiled in lime water to remove the activity of bamboo and vegetable oil, and soaked in wood tar to prevent moths......"

Guo Ziren opened his mouth and asked: "What is activity?" The bamboo is like that, and it will still live......"

Song Ziqiang said: "Don't talk nonsense! How long should lime water be boiled and how long should wood tar be soaked? Say! ”

Guo Ziren opened his mouth and said: "After the lime water boils the bamboo and bamboo strips, slowly dry in the shade, and then soak them in wood tar for a day, and then dry them in the shade......

Song Ziqiang said happily: "Good boy, so smart!" ”

Guo Ziren immediately grinned.

"Then you'll be in charge of this job from now on......"

“…… No! Master Song's family, I want to be with my companions. ”

"Then let them do it with you! You command ......"

"Okay, Master Song, let Yang Youxing go and mix concrete!"

"This personnel arrangement, you say ......"

"Very good!"

In fact, the properties of different types of bamboo are quite different, the quality of bamboo reinforcement is difficult to control, the elastic modulus is too small compared with steel, and its cross-section deformation is large, so it can only be an alternative product.

But there is no doubt about the degree of robustness.

When Huang Zuxiang passed by here with two large piles of bamboo cages, he doubted the sturdiness of the cement slab.

At that time, Huang Zu's body had just recovered, and Wu Dapeng arranged a light job for him to manage bamboo processing.

For example, weaving bamboo baskets, bamboo baskets and the like, of course, bamboo furniture is also available.

Huang Zuxiang put down the bamboo cage at that time to watch, these things were originally going to be sent to the salt field to load gravel to repair the seawall.

He said, "How can that object be strong?!" ”

Song Ziqiang squinted at his figure, estimated that he was only sixty kilograms, and said, "You can give it a try......

The bamboo-reinforced cement board was erected with bricks by half-sized people.

In fact, the half-sized child also wants to know whether this thing is strong or not...... But everyone found that whoever dared to question the Song family, he seemed to retaliate, and could only believe everything he said.

Huang Zuxiang went up cautiously at first, for fear of breaking it, and his movements were like a peasant who had just arrived in the city in that world, walking on the fiberglass stairs.

Song Ziqiang knew in his heart, this prefabricated bamboo bar board is one meter five long, seventy centimeters wide, and the density of bamboo tendons is 10 centimeters, so there is no problem with 300 kilograms in theory...... If it were Portland cement and high-quality steel bars, even if it was a thousand kilograms, there would be nothing at all.

Huang Zu felt that there was nothing wrong with him going up, so he said: "Song Chuanshou, I'm going to jump...... It's broken, don't blame ......"

Song Ziqiang blurted out: "If you want to step on it, I will pay you a store house!" Good location!! ”

Huang Zuxiang didn't believe it, he worked hard, hey!

He really jumped, high, and stepped on it hard!

But no one can go against the common sense of physics......

The cement slab made a "thump" sound, and seemed to tremble, but nothing happened!

Song Ziqiang immediately said: "The boys all go up!" ”

Haha, the half-sized people couldn't wait for a long time, and they all jumped up immediately, but there wasn't enough space on it, only eight people could stand, and they were all hugging each other...... There was nothing wrong with that cement slab.

They shouted, jump together!

Everyone barely jumped...... It really collapsed, it was a broken brick!

Guo Beyu was happy just now, duang! fell a big heel...... It hurts......

Song Ziqiang glanced at him, the kid was fine, and then looked at the cement slab, maybe it was buffered because the bricks were broken, very good, it was still no problem.

Huang Zu's eyes lit up, he touched the brown cement slab, and said, "If this thing is used to build the city wall......

Song Ziqiang said lazily: "You better go and send the bamboo cage, we have to use it to build a salt pond first......"

Huang Zuxiang said flatteringly: "It's overkill...... No, no, it's just right to build a salt pond! ”

Song Ziqiang said strangely: "You also know about salt? ”

Huang Zu said: "I have seen it, and the sea water of the reef quickly turned into salt......

It's okay, it's not stupid at all!

Song Ziqiang ignored his interest, and then said to the half-grown children, "How is it?" Does Romanesque cement work? ”

Wu Jie laughed at the time and said, "It's very useful!" ”

Huang Zuxiang smiled wryly, picked up the picket and went to deliver the goods, and the indigenous girl followed behind him, still holding a bamboo tube...... Song Ziqiang was vaguely jealous, a person who did manual work, and even a secretary who held cold boiled water!

Song Ziqiang built this prefabricated bamboo cement to prepare for the manhole cover of the pressure water well and several embankment teeth of the salt field.

If it is made by stonemasons, it will have to wait until the Year of the Monkey.

Three-meter cast iron pipe, pressure wellbore, pressure handle, tuk inner tube pad...... They have also tried to use whale skin, deer skin, and wild boar skin in advance, but none of the inner tube cushions have a good effect, and they do not have it to resist wear.

The first cast-iron pressure well in human history was born in the time and space of the Great Song Dynasty.

Song Ziqiang asked Wu Di, a half-grown son, to scoop a shell of water with a coconut shell and pour it into the wellbore, and then began to creak up and down and press it up and down.

At this time, Song Ziqiang asked Wu Di to put some whale oil on the pressure shaft...... Or the sound is too ugly.

Where do the onlookers care about this, they are all people who work in the dry fields, if this object that can be pressed out of water like this according to the head of the Song boat is really useful, it is much less labor-saving than drawing water in the well......

Song Ziqiang pressed more than ten times in a row, and sure enough, the water came out!

But the water was tan...... This is because impurities on the iron castings affect the water quality, but it will be fine for a while.

Wow! The onlookers watched the arm-thick water flow out continuously under the action of pressing and pressing, and they kept shouting incredulous!

Wu Di thought arrogantly beside him, Master Song's family told me that it was using a vacuum, do you understand?!

Actually, he doesn't know much about it...... But he knew that if he did it according to the method of Lord Song's tutor, it would definitely work.

Song Zi was annoyed by the pressure, he stopped his movements, saw that the water could still flow for three or five seconds, and then, after the water in the pressure wellbore seeped out, he said:

"Wu Di, you scoop up the water yourself and try it......"

Wu Di was a little scared at that time, did he have to put himself in charge of pressing water in the future......

Song Ziqiang understood as soon as he saw his expression, and said, "What are you thinking?" Give the dog a steamed cake for this job, and the dog will do it! Let everyone try it when you're done......"

Song Ziqiang turned around and left, he didn't care if others would catch the water.

It's a pity that everyone has no cigarettes, so it's no wonder that Hu Zhenbei always begs them for cigarettes, saying that they can't smoke for a day......

As soon as Song Ziqiang left, everyone was active, everyone gathered together, and as Wu Di also played out the water, everyone laughed.

The main point of the pressure well is to have good sealing, and it is just right that the sealing of the two main departments can be completed by mule cement and leather pads.

Soon, the miscellaneous soldiers who managed the dry fields were fighting to dig the second and third wells.

Life is like this, when everyone is actively preparing to fight the spring drought, God it rains, and it is three days at a time......

I'm worried about death, not to mention the impact on work, but also to prevent waterlogging.

The water of the small stream south of the Badao River suddenly rose, and the original overflowing dam was washed away in several places!

Wan Shida immediately threw off the bamboo coat, picked up the bamboo cage full of gravel, and jumped into the water to plug the gap.

Those half-grown children were ordered by him to stay on the shore, they were not yet adults, and they were afraid of running away when they went into the water!

Many miscellaneous soldiers also carried bamboo cages and rushed down the stream!

Fortunately, the water potential is relatively large, but it is far from flood level, and the vegetation upstream is dense, and countless plants are sucking this rain.

Many large bamboo sheds have long been built in the big bamboo village at the mouth of the Badaohe, which was originally prepared for the rainy season, but I didn't expect it to work now.

At that time, they were still afraid of fire, and the large bamboo sheds were a little farther away from each other, and they found that it was a mistake that they did not build a bamboo canopy corridor, and it was quite troublesome to walk around each other every time.

The bamboo coat was too bulky.

There are more people who help with bamboo tools, and more people who help process wood tools.

Twenty and a half children were also busy in the big bamboo canopy, and Song Ziqiang asked them to use up all the mule and horse cement in the warehouse, because they didn't want to bother with its moisture-proof work.

So, twenty and a half people began to be busy making prefabricated bamboo cement parts.
