Song Ziqiang said loudly: "As long as people don't die, nothing can be called failure!" You went to hunt sambar deer, but you didn't hit it, but you hit a litter of rabbits, and you hit a pig wild, do you say this is called failure? …… Right? ”

Wu Jie nodded in agreement. Pen, fun, pavilion www. biquge。 info

The argillaceous limestone they mined was tan, so the mule and horse cement they fired was also tan, which could be seen from Wu Jie's face.

The half-sized children never knew what Rome was, and always thought it was the mule and horse, so Song Ziqiang didn't bother to tell the story of Rome...... So, let them scream and get angry.

On this plane, it doesn't matter what the name is.

Their calcining kiln may have put too much charcoal in it, and the blasting effect is too good, so there is an overburning.

But there is still a suitable one, but less than a quarter is available.

Song Ziqiang said loudly: "Look, the one picked out is easy to use, right?" Next time, as long as you put a little less charcoal, it will be European, why do you say failure? On the road of scientific exploration, you will encounter countless such so-called 'failures', at this time, don't be afraid, keep coming......"

Wu Jie nodded in agreement.

As a result, there were too many underfires in the second kiln...... This temperature requirement is really different from that of burning lime.

What is the use of argillaceous limestone that is underfired?

Song Ziqiang pulled a pile of argillaceous limestone fragments that were underfired, and said: "Use it to pave a cement road, it's a good thing, it has a strong affinity with mule and horse cement......

Wu Jie nodded in agreement.

After a few times, Wu Jie finally mastered the ratio of charcoal to argillaceous limestone fragments, as well as the firing time, and even the size of the blast air volume...... From now on, the yield is getting better and better every time.

Song Ziqiang said loudly: "Look, you have learned, you will become a glorious mule and horse cement factory director!" ”

Wu Jie shook his head in disgrace and said, "I want to be with my partners!" ”

"Fool......" Song Ziqiang said with a smile, "You can command the miscellaneous soldiers to work after the kiln material is ready, and if you understand the technology, you don't have to do manual work......

Wu Jie finally smiled, this kid's teeth are quite white, maybe it is reflected in the gray on his face.

They decided to build a salt pond.

In this time and space, salt is a precious living material, and on the territory of the Great Song Dynasty, smuggling more than 20 catties of salt will be sentenced to death, which shows how much they care about salt.

It is also an important production material for the six space-time smugglers, so it has to be produced and processed very early.

Now, the spring ploughing production work has passed the most intense time, and the rest is to quiet the breeding base itself can be busy.

It's basically new species that don't exist on this plane.

This evening, Zhang Guoan and Wu Dapeng walked on the bank of the Badao River.

Their waterwheels were rumbling, windmills were whirring, and the water from the trucks was flowing in a stream in the waterway.

The evening breeze stirs their long hair, which is pleasant.

Zhang Guoan said; "Go back, I can see that Hadron is in a hurry...... I can do the rest of the work. ”

Wu Dapeng came up on the river bank at this time and made a two-legged standing long jump, which was okay, two meters and five.

Back to the world on that side, is there a meter five? He didn't even dare to try.

Wu Dapeng looked at the colorful sunset on the horizon and said, "There were only two light rains here at the beginning of spring...... What if there is a drought this year?

Let's wait for Song Ziqiang to finish the pressure well, and we will finish the salt field at the same time.

Even if it's a one-time job? Don't worry, I can convince him on the hadron side......"

Now for them, the pressure well is easy to build, they have mule and horse cement to build the seal of the well wall and the wellhead, and they also have the inner and outer tubes of the three-wheeled motorcycle to make the sealing ring.

As for the work of building water wells and casting cast iron pipes and iron castings for pressure water wells, it is a very easy thing.

The groundwater in this plane is so abundant that even the island of Xiaoliuqiu can easily dig a well.

In that world, there are more than 100,000 people living on the island, and of course a lot of fresh water is needed...... And now there are less than 200 natives on the island, or have they learned to bathe under compulsion, and how much water do they need?

At that time, some peanuts were needed......

Therefore, preparing for spring drought is still a big thing in their hearts, and the pressure well is a very important drought prevention facility.

They did not dare to touch the coastal mangrove forests in the estuary area when they were deforesting and burning the land, and it was their presence and the abundant water volume of the Badao River that prevented the sea water from eroding the inland and causing salinization of the land.

These coastal mangroves are important!

When they developed the paddy fields not far from the mouth of the river, the pH value of the land was measured, otherwise they would not dare to develop if they were killed, and their hard work would be in vain.

But the question is, there are advantages and disadvantages, what if this is to reclaim the salt pans?

Some coastal mangrove forests must be destroyed.

Huang Zu said disappreciably: "How convenient is it to boil salt...... There is firewood here, and there is no shortage of iron pots and manpower! ”

This kid is in good health...... I didn't rest for a few days when I came back, but I recovered immediately, and I started to look around again, asking this opinion, that opinion.

But now he has a little tail, and the native girl named Nana follows him all day long, sleeping with him in a bamboo building.

Wu Dapeng once hinted that she was too young at this time...... Do you understand?

Huang Zu's big face turned red at that time, and he said loudly: "Wu Shibo! He is a righteous man and a gentleman...... Mo said that he was a wild man, that is, ......"

"Alright, alright!"

Wu Dapeng was annoyed, so I just said a word, do you need to say so much?!

Now no one can separate this little native girl from him, and Quiet has tried, but her screams can be as loud as 200 decibels!

Resounding through the clouds.

Quiet finally gave up her efforts, saying: "When a person suddenly encounters someone who rescued her in extreme terror, she will have a feeling of complete conformity, and it will take quite a long time to dispel this strong psychological imprint......"

Wu Dapeng felt interesting, there is such a thing in people's psychology......

He asked: "If a people suddenly encounter someone who rescued them in the most critical situation, will this ...... What kind of mental imprint? ”

Jing Jing said: "The educational psychology I studied only refers to education and teaching...... But I know that lies can be used to create a collective psychological imprint, and in extreme cases, after being deceived for decades, he will still believe the original deception! ”

Wu Dapeng suddenly realized at this time and said, "What did I say...... Those who have been fooled still insist that they are not a big percentage, right? ”

"Even if it's not much, but they'll find their kind to reinforce each other's false psychological imprints...... Extremely stubborn. ”

Wu Dapeng said: "This is a lesson! If anything happens to us in the future, we will kill the liars! ”

Jing Jing understood what he meant, and said, "No, just show the truth......

Wu Dapeng stopped talking, but he already had a way.

When Wu Dapeng heard Huang Zuxiang's suggestion to boil salt, he said: "You Great Song people have no way to boil salt, the cost is too high, and the efficiency is too low......

Huang Zu went on to say: "But it's extremely convenient! ”

For now, it's true that iron pots and dried reed grass are being used to cook salt, but it's only expedient.

Wu Dapeng didn't want to convince him, and wanted to let him see it with his own eyes after it was built.

They avoided the mouth of the river, and on the right bank of the Eight Dao River, found a place of bay.

Wu Dapeng ordered to cut down all the mangroves on the coast!

Thousands of miscellaneous soldiers began to move.

Mangrove is also a very useful tree species, for example, red dye can be extracted from its bark, and if sodium sulfate is used to help dyeing at the same time, the effect is far better than the level of printing and dyeing in this time and space.

However, it is not timber, the diameter is too small, not to mention, the trunk is particularly curved.

Therefore, after picking its bark, it can only be dried as firewood...... But it's also good for felling.

After three days of continuous logging, they cleared a 500-meter-long working face.

In their plan, the first step in the salt plant was to build a seawall.

Its construction will account for 80 percent of the work of the salt works. Of course, it also has a great effect, when the sea water is high, the sea water can pour into the first-class salt pan through several embankments reserved on the sea wall, and then put down the embankment gate, you can leave the sea water.

Of course, the technical requirements of this gate are relatively high, not only to smoothly lift and fall, but also to block the impact of seawater return, and now they have hardwood, there are also woodworking machine tools, are carefully processing it.

The second step is the construction of salt pans.

When reclaiming salt pans, the surface sediment soil is dug up.

When everyone else went to cut down the mangrove forest, Wu Dapeng shoveled the soil on the shore of this small bay himself.

When he had reached 60 centimeters, he finally revealed the layer of clay that he liked, which effectively prevented seawater from seeping.

Once they've built a seawall, they can dig it.

If there is a leak in this clay layer, it can be filled with clay and compacted.

After that, all the ground in the salt pan was rolled several times with stone rollers.

The third step will be a second-class salt pan made of mule-style cement.

They were to build several saltwater pools of 25 meters by 50 meters and 20 centimeters deep out of mule-like cement.

These pools are interconnected, and the reason for the depth of 20 centimeters is that it is conducive to rapid air drying and rapid salt production.

After about a week of evaporation, the concentration of the seawater in the first-class salt pans will increase from 3.5 percent to about 18 percent, and then the high-salinity seawater will be raised to the second-class salt pans.

If you want to improve the uniformity and quality of the salt grains at this time, you need to mix it several times a day, which is very low-tech and requires a little physical effort.

When the seawater with 18% salinity is exposed to sunlight and blown by the wind, it begins to crystallize in the secondary salt pans, and white flower crystalline salts will appear at the bottom of the pond.

At this time, you don't need to wait for the water to completely dry, you can use a wooden plank to sweep the salt and return the salt, and if the weather is good, you can sweep it once a day.

The rest is dried again, and so on.

That's how their plan was designed.

Seawater can automatically flow into the first salt pan by its own gravity, and then be trapped.

But the promotion to the second class of salt pans required additional power, and they were going to use a few small windmills to automate the brine.

Of course, manual vehicle water is also possible, and the pedal vehicle water tools of the Great Song Dynasty in this time and space are more common in rural areas.

To be honest, Song Ziqiang also studied their pedal water tools.

The structure of their treadmill is very delicate.

The total length of the pedal waterwheel is more than 5 meters, and it is a pure wooden structure, and not even a single iron nail is used.

The body of the waterwheel is equivalent to a long, semi-enclosed wooden box, with openings at both ends, one end absorbing water and the other end coming out.

Inside the long wooden box is a small wooden bucket composed of small square wooden blocks, which are then connected to a movable wooden connecting rod at an equal distance. The long wooden box has a coarse shaft with wooden gears that can be rotated at each end, and a small wooden bucket on the movable wooden connecting rod is just right between the gears.

The thick shaft of the suction end is sealed inside the waterwheel, and the thick shaft of the water outlet end is across the head of the waterwheel, and the length of each side is more than 100 cm.

A wooden frame like a horizontal bar is erected directly above the thick axis of rotation at the head of the waterwheel, and three or four people can pounce on the wooden frame at the same time, and step on the pedal in unison, and the work of lifting water begins.

The thick axis of the waterwheel rotates, so the small wooden buckets in the waterwheel rotate very coherently, and the end that absorbs water is placed in the river or pond, and the water will be continuously lifted up with the rotation of the small wooden bucket.

Song Ziqiang sighed and said: "The craftsmen of the Great Song Dynasty are also very smart, if they are not interrupted by the Tatars, do you say, will they evolve to iron gears or axles?" ”

Zhang Guoan said with a smile at the time: "History cannot be assumed...... But we can change, don't you want to see the consequences of change? ”

Song Ziqiang sighed and said, "Come on, let's live by myself first......"
