"My masters, I'm going to build a reservoir here!

I also have to worry about all the masters and take a closer look. This place is suitable for building reservoirs!

How much labor, how much money is required, and how long does it take to complete it!" Zhang Junping was still very polite to these capable craftsmen.

Or in other words, except for the enemy, Zhang Junping is very polite to anyone.

Zhang Junping was kind-hearted, but several craftsmen did not dare to neglect. They followed Zhang Junping's order to investigate the terrain, measure the length of the valley mouth, calculate the working hours and material usage.

It took about an hour before the craftsmen surveyed the terrain and calculated the useful materials.

"Reporting to the magistrate, the construction of a reservoir in this canyon is unique, and it is actually the best choice!

The word "reservoir" mentioned by the magistrate is even more incisive and clearly points out the role of the reservoir..." Lao Hegong praised it vigorously.

The reservoir was not invented by Zhang Junping. As early as the Xia, Shang and Zhou dynasties, there were simple versions of reservoirs. "Records of the Grand Historian: The Annals of Xia" and "The Literature of Zhou" all have records about reservoirs, but at that time, it was not called a reservoir.

"Records of the Grand Historian: Xia Benji" records that Dayu used to control floods and "Nine Lakes". This "Nine Lakes" refers to surrounding the depression with mud and stones to store water.

The "Book of Zhou" also records that farmers who plant rice fields built "stag" to store water.

This is the earliest simple version of the reservoir.

In this time and space, it can only be said that the word "reservoir" was invented by Zhang Junping.

The word "reservoir" first appeared in the Ming Dynasty in history. Before that, there were many different names, including ponds, ponds, lakes, stags, water cabinets, etc.

But the final meaning is the same, both refer to reservoirs.

"Let's talk about how much labor and money it takes to build a reservoir dam!" Zhang Junping stopped the old Hegong's flattery, and he was a little doubtful in his heart whether he had found the wrong person.

"As long as this canyon is blocked, it will be a natural reservoir!

The valley mouth is 365 meters wide, and the cliffs on both sides of the canyon are dozens of meters high and thousands of meters deep. As long as a dam twenty meters high is built at the valley mouth, the canyon can store millions of stones of water!" Old Hegong said a lot, and just when Zhang Junping was about to interrupt him again, Old Hegong came to the point.

"This embankment is 385 zhang long, twenty zhang high, one hundred zhang wide at the bottom, and ten zhang wide at the top...

If two thousand people are used, it can be built in two years!"

"Two thousand people, two years..." Zhang Junping pondered in his heart.

If a worker calculates a monthly payment of 48,000 guan, it is still possible to bear the labor cost.

"This embankment is related to the comfort of the people of Mouping County, so the villain believes that it is best to use three-fold soil to build the embankment, which can be safe! "

"Use three-fold soil to build a dike?" Zhang Junping was startled.

If you use three-dimensional soil to build a dike, the price will be higher.

Sanhe soil is a building material made by mixing clay, yellow sand and lime in a certain proportion.

"If you use Sanhedi, how much does it cost? How much time does it take?"

"If we burn lime ourselves, we can leave a lot of money, specific... specific... the magistrate atones for sin... the villain is dull and cannot calculate..." Old Hegong said hesitantly.

It is normal to not calculate it. A dam with a length of 385 zhang, a bottom of 100 zhang, a height of 20 zhang, and a top of 10 zhang, a dam with a three-million soil alone requires more than 10 million cubic meters.

In this era, there are tens of millions of calculations, not to mention an old river engineer, many teachers in academy need to calculate for a long time.

However, there is one thing that Zhang Junping agrees with the old Hegong's view, that is, to build a dike with three-fold soil.

Anyway, the ten major families have paid money, so what are he afraid of?

But they didn't know what expression Zhang Junping would look like when he planned to use Sanhedi soil to build a dike and whether he would cry.

A cubic cube of three-combination soil requires two or three hundred coins even in the Northern Song Dynasty.

More than 10 million cubic cubic meters of three-combined soil would be two or three million guan. This has not yet been calculated for the cost of repairing canals and roads and bridges. The total amount would probably cost 5 million guan.

I don’t know if these ten major families are willing to spend five million jin of money to divert their attention.

If these ten major families are really willing to spend five million guan, Zhang Junping is ready to let them go.

They pretended not to know about their stealing gold or silver mines.

Everyone will play their own games in the future.

After returning to the county government, it was time for lunch.

Zhang Junping arranged for Sun Xu to take the craftsmen to the county government canteen for dinner.

I also went back to the Houya for dinner.

After lunch, Zhang Junping made a cup of tea for himself and savored it slowly.

After a while, Liu Daojie rushed back from Banshan Gu Academy and reported to Zhang Junping about the reconstruction of Banshan Academy.

"Reporting back to the magistrate, Mr. Gu and Mr. Xu were very satisfied with the transformation of the Banshan Gu Castle into academy!

My subordinates have found some craftsmen to renovate the castle for several days, and it is expected to be completed the day after tomorrow!"

"Thank you, Chief Liu!

When Banshan Academy opens, Liu Zhubu is a great achievement. In the future, students of Mouping County will remember everything Liu Zhubu has done for them!" Zhang Junping praised with a smile.

"I dare not take credit for it. This is just what I should do!" Liu Daojie quickly said modestly.

"The chief clerk Liu doesn't have to be humble. In this official, merit is merit, and mistakes are faults!

After the reconstruction of Banshan Academy is completed, you can erect a merit monument in the academy. The name of the person in charge of the reconstruction is your Liu Zhubu!

In addition, the names of all donors are engraved on it, so that the students of the academy remember that whoever they have received and who is supported by them can read with peace of mind and study with all their hearts!"

"This... the magistrate is of great advice! In this way, the gentry in Mouping County will definitely donate money and materials enthusiastically, so that their names can be engraved on the merit monument!" Liu Daojie bowed to Zhang Junping sincerely.

"For this matter, let's communicate with the big families in Mouping County first. They are all the leading figures in Mouping County, and they need to take the lead in this matter!"

"Students go back and do this!"

"Yeah!" Zhang Junping nodded, "There is one more thing.

You told me today that the gentry of Mouping County is willing to pay and support me to build a reservoir and canal, but it is true?”

Zhang Junping looked at Liu Daojie with a serious face and asked solemnly.

"Of course it's true, how dare the students deceive the magistrate!" Liu Daojie, who was instructed by the head of the Li family, nodded with certainty.

"That's good, the official was still worried! The cost of building a reservoir is too great, and it is difficult to support it with the county.

With the support of the gentry from Mouping County, it would be easy to deal with!

According to our calculations, it takes 5,000 people to build reservoirs, canals, roads and bridges, which takes two years to complete! It is estimated that the money will be about 6 million guan!
Chapter completed!
