Zhao Dezhao relieved that a series of trivial tasks such as rice transplanting and insect removal in Zhancheng were handed over to those old farmers, for planting this piece is not his specialty after all, and now the most important thing is to supervise the affairs of the supervision and the ordnance superintendent, since the last time the development of firearms and the improvement of armaments were handed over to the craftsmen of the ordnance superintendent, so far the firearms are still under development.

After the beginning of spring, the wind and the sun are beautiful, and the earth warms up. After the fields are reclaimed, the farmland near Kaifeng has begun to introduce water sources, and the next step is the link of rice planting for the old farmers.

The plan of the year lies in the spring. At this moment, in the fields, the farming work began, and the old farmers in the paddy fields outside the city rolled up their cuffs, wore hats, took off their shoes and socks, wore short clothes, and bent down to plant seedlings.

There was a faint smell of grass in the air, Zhao Dezhao sniffed suddenly, and suddenly felt refreshed, and his feet had unconsciously climbed to the top of the city tower of Xuanhua Gate, at this moment, there was a look on Xuanhua Gate that looked like a craftsman, but stared at the craftsmen who built Jinmingchi outside the city and sighed a little.

"This big brother, what is the reason to lament?" Zhao Dezhao asked when he saw the man.

"Little brother, why are you on the city wall, here are not allowed to idle people to go up to the city tower." This person stared at Zhao Dezhao, Zhao Dezhao was dressed in a plain robe, although his face was plump, but the clothes were a little ordinary, and the man looked at it carefully for a while and didn't know which child's son and brother this child was.

"Hey—there's something you don't understand, little brother. A certain person was very troubled in his heart, so he was depressed ......in his heart, and then he said the troubles in his heart, and then Zhao Dezhao told him some knowledge of the future life, and the person suddenly realized that he was a little bit bit of it.

The two talked for a while, and the man left first because he had something to do, leaving only Zhao Dezhao standing on the city wall.

At this moment, outside Xuanhua Gate and Shuntian Gate, 10,000 civilian servants are digging and digging soil, and their sweat is dripping on the land, but they can't fill this pool. Their task was to dig a pond, and the civil servants who carried the soil to the side carried the soil aside, and the project was carried out in an intense and orderly manner.

In order to complete the pool widening project of Jinmingchi as soon as possible, and 10,000 civilian servants were not enough, Zhao Kuangyin, the son of the Great Song Dynasty, transferred another 50,000 to reluctantly speed up the project.

After a month's work, the pool where the Jinming Pond was excavated was already a foot deep, and it had begun to take shape from a distance, and the young laborers were still digging out the soil at the moment, because such a depth could not meet the depth of a large warship.

Zhao Dezhao stood on the Xuanhua Gate at the moment, looking at the 10,000 civilian servants digging the pool, and from a distance, the pool that began to take shape still made him feel quite shocked, because in ancient times, a large-scale project had to rely on the conscription to undertake, as we all know, when Qin Shi Huang built the Great Wall, just by dispatching conscripts from all over the country, millions of them were mobilized, and the construction of the mausoleum of Qin Shi Huang also used a lot of manpower.

What's more, the Bianshui connecting Kaifeng and other artificial rivers, Yang Guangke of the Sui Dynasty died tens of millions of dollars in order to complete this project, so the rational use of forced labor is the key, so as not to cause public resentment to boil and the country to be in danger.

The recital above the court has been approved, Zhao Kuangyin is busy, and plans to go outside the city to see how some Jinmingchi is built, so accompanied by the inner servant Zhang Dejun, the two of them paid a private visit and also climbed the tower of Xuanhua Gate.

When he looked at the Jinming Pond built by 60,000 laborers, he also sighed in his heart, if the whole country is unified, it will take so much effort to build Jinming Pond outside Kaifeng City, but the Great Song Dynasty Navy is still the opponent of the Southern Tang Dynasty Navy so far, and in the process of unifying the south, it is bound to use more warships.

The northerners don't know water, but the southerners know how to water, which is why Cao Cao connected the warships together in the Battle of Chibi, and in the end, a fire hindered his southward progress. Just ask him Zhao Kuangyin is not Cao Cao, and Li Jing's generation is not Sun Quan Zhuge Liang's person, so the depressed color on his face was swept away, he looked forward to the rapid construction of this Jinming Pond, as soon as possible in this pond water to carry out water war drills, and then the warship covered the sky and the sun to the south, unified Jiangnan.

"Daddy, you're here too!" Zhao Dezhao was staring ahead, his thoughts were flying, so he didn't notice that Zhao Kuangyin had been standing behind him for a long time.

"After Daddy got off the morning court, he couldn't bear to walk here to see how the Jinmingchi was built, looking at this, Jinmingchi is estimated to be repaired in more than half a month."

"These 60,000 people don't seem to be enough, and 20,000 laborers have to be mobilized, so that the burden on the remaining 60,000 laborers can be lightened a lot, and their welfare must be improved during the labor period, so as not to make them resentful of the court."

"Hmm!"

At this moment, the teaching ship official hurriedly ran up to the Xuanhua Gate Tower, and when he saw Zhao Kuangyin, he immediately said: "Your Majesty, now the shipbuilders from all over the country have been supervising the construction of warships outside Kaifeng City, and it will not be long before the Great Song Dynasty Navy will be able to search for more warships." ”

"Oh? A hundred searches? How long will it take to build? Zhao Kuangyin asked urgently.

The official of the teaching shipping department told the truth, "Now the teaching shipping has more than 30 warships have been built, and the rest are still under construction, because there are not many big trees near the capital, last month in the upper reaches of the Yellow River felled big trees, and then placed in the river water, in the north of Kaifeng City through the river transport, and for a while there is really not so much large wood." Moreover, the ships that went to Zhancheng with the envoys of Zhancheng last time and the Liuzhou Pioneer Group brought some ships, and there are only so many ships in the Jiaocheng Ship Service now, and their warships are slowly being built. ”

"I'm going to teach the ship and personally inspect the construction of the ships there, and Zhao'er, you'll go with me."

"No!"

Coming down from the city tower, Zhao Kuangyin and his entourage went to the teaching shipping wharf in the north of Kaifeng City under the leadership of the teaching shipping officials, and washed away some small boats when the Yellow River was flooded this year, but fortunately the damage caused was small, but it was a great responsibility for some people who guarded the boats, and at this moment Zhao Dezhao also heard about this matter.

Arriving at the pier, more than a dozen warships, large and small, docked on the banks of the river. On the banks of the river, there are many types of boats, according to Zhao Dezhao, these boats include warm boats, shallow bottom house boats, shallow boats, two-masted multi-oared boats, icebreakers, etc.

On land, the workers laid logs on the bottom of the boats in advance, and then put them back into the river after the boats were built, and then it was really laborious, and the Yellow River was often flooded, and a person who did not do well could protect the boat would bear the responsibility for losing the boat.

In a hurry, Zhao Dezhao planned to ask the officials of the shipping department, and he knew that the newly built boat was often in danger of being lost by the turbulent river, and at this moment, a person who looked like a small official next to him walked up, and he respectfully arched his hand and said: "The minister and supervisor Mu Zhangping knocked to see Your Majesty, Your Majesty has something to say." ”

Zhang ping? This...... It seems that he has heard of this name, and as soon as the person raised his head at this moment, Zhao Dezhao recognized that he had already seen it on the city wall.

Belch...... As soon as the two met, they began to be stunned.

"What's the matter?" Zhao Kuangyin asked, since someone has an important report, I want to hear what that person has to say.

"Your Majesty, why don't you divert water, divert water through the pool, and tie the boat into it, so that you can avoid the labor of guarding the new shipbuilding, and you can also avoid the upstream water washing away the ......boat when the river floods" Zhang Ping didn't finish speaking, he looked at Zhao Dezhao's face when he said it, but His Royal Highness King Liang's face was not angry but happy.

Zhang ping? It turned out to be the ancestor of the inventor of the dock, Zhao Dezhao suddenly remembered, but this was also ten years in advance, hehe, isn't this dock what he said on the city tower.

But Zhang Ping was also a little entangled, it turned out that it was His Royal Highness King Liang who was talking to him on the top of the city tower today, but now everything he wanted to say was what His Royal Highness King Liang said to him, so he was a little hesitant and embarrassed to say it.

"Just speak your mind in front of Your Majesty! It doesn't matter! Zhao Dezhao said this to ease his nervous mood.

When Zhao Kuangyin heard the words of this little official, he also felt that his idea was good, "Oh! Tell me more about it, I'm very interested in your suggestion. ”

"Yes, Your Majesty." Zhang Ping then reported the original idea of the dock and the specific implementation to the emperor, and the emperor was overjoyed when he heard it.

In fact, this method is the canal pond berthing method, if this is indeed able to avoid a lot of trouble, so Zhao Kuangyin and the official listened, suddenly felt that it is a good method, Kaifeng around the water system developed, Cai River, Wuzhang River, Bianshui and so on around Kaifeng through the city, and now Jinming Pond is being excavated, after the completion of the excavation of Jinming Pond, and then lead the water of the Cai River, the dock site will be relocated to Jinming Pond, but so Zhao Kuangyin feels that Jinming Pond is still not big enough, so he thinks that Jinming Pond is still several times larger, Or dig a pond in another place, lay sleepers underneath, and then divert water into it after the boat is built, so whether it is Jinming Pond or a dock, it must be connected to other rivers.

"Spread my will, according to what Mu Zhangping said, through the pond to divert water, tie the boat to it, in the new shipyard outside Kaifeng City, this place is not far from the Yellow River, Mu Zhangping of the city has made a meritorious contribution, I promoted him to be an enshrinement officer, and then the new enshrinement officer Zhang Ping was ordered to supervise the construction."

"No!" Zhang Ping knocked on Longen, led the order and began to go down, and looked at Zhao Dezhao before leaving, as if to repay the gratitude.

After the order, the construction of the existing ships on the site was still in progress, but the dockyard chose to supervise the construction in other places, close to the water source.

After that, Zhang Ping ordered the migrant workers to dig a large pit on the shore, build a boat in it, and after the boat was built, dig a hole, divert water into the pit, and the boat floated up and sailed into the river. The big pit is called "dock". And Zhao Dezhao also took advantage of his free time to go to see the dock that Zhang Ping ordered to build.

Zhang Ping saw that Zhao Dezhao's face was a little flustered and embarrassed, "Your Highness...... Minister......"

"Lao Zhang, why are you so nervous, I won't eat you."

"Your Highness, I'm really sorry that I reported everything Your Highness said to me."

"It's nothing, you're still care, how can this king be a person with a small belly, and things that benefit the country and the people, this king doesn't care, now that your official position has been promoted, you will have to serve the country well in the future."

"Hmm! Thank you, Your Highness, and I am grateful. ”

The dock began to be built under the guidance of Zhang Ping, because of the matter of cement, Zhang Ping's operation of the dock method is more simple, according to his idea and with the improvement and assistance of Zhao Dezhao, he designed two kinds of docks - dry dock and floating dock.

Zhang Ping ordered people to build a dock in a place in Kaifeng, of which the dry dock is connected to the land on three sides and faces the water on one side, which is divided into a dock mouth, a dock chamber and a dock head.

The dock mouth is equipped with a water retaining dock door for entering and exiting the ship, and the drainage and irrigation equipment is built in the dock piers on both sides of the dock mouth;

The dock chamber is for placing the ship, and the keel pier and the side pier supporting the ship are arranged on the bottom plate of the dock chamber;

The head of the dock is opposite to the mouth of the dock, and its plane shape can be rectangular, semicircular and diamond-shaped, and the space of the head of the dock is part of the dock chamber, where the propeller and the tail shaft are disassembled and assembled.

When the ship enters the dry dock for repair, first fill the dock with water irrigation and drainage facilities, and when the water level in the dock is level with the outside of the dock, open the dock door, lead the ship into the dock, and then drain the water body in the dock, so that the ship sits on the keel pier. It's just that pumping is now done manually.

When the ship is undocked after repair or construction, water is first poured into the dock, and when the water level inside and outside the dock door is level, the dock door is opened and the ship is undocked.

The other is the floating dock, which is a concave cabin that can be moved and floated and sunk. It is used for repairing and building ships.

The construction of the dockyard was also underway, and the navigation industry of the Great Song Dynasty was also booming.

______________________________________________________________

ps. The dock was invented by Zhang Ping, a native of the Song Dynasty in China. According to historical records, Zhang Ping (925-987), a native of Linqu Yangshan, successively served as Marquis of Mabu in the Northern Song Dynasty, Jianshi Mu, Enshrined Official, Jianyang Pingdu Wood and Shipyard, Deputy Envoy of Chongyi, Rujing Envoy, Guest Provincial Envoy, and Salt and Iron Envoy.

In 977 A.D., Zhang Ping served as a worship officer, supervised Yangping Dumu and shipyard, and lived in Yangping Town, east of Baoji City, Shaanxi Province. At that time, when building a ship by the Wei River, it was easy to be washed away by the water, so I had to send one boat and three households to guard it, and thousands of migrant workers were recruited and transferred a year, which cost the people and money. Zhang Ping then ordered the migrant workers to dig a large pit on the shore and build a boat in it, and after the boat was built, dig a hole, divert water into the pit, and the boat floated up and sailed into the river. The big pit is called "dock".
