King of Song

Chapter 440

The reason why the Yellow River often bursts is because the sediment content is high, and the gradual siltation makes the river bed higher and higher.

It is a well-known truth that if the water flow slows down, the sediment will settle more easily.After the Yellow River leaves Sanmenxia, ​​it is almost all plains along the way, the drop is small, the speed of the water flow slows down, and the sediment deposits and silts up. As time goes by, the river bed becomes higher and higher, and even becomes an above-ground river.

Therefore, officials in the Northern Song Dynasty all had a wish that if water could flow from the ground, the flood would be alleviated.To achieve this, there are two ways, one is to speed up the water flow, reduce sedimentation, and also be able to impact away the previously deposited sediment, making the river gradually deeper.

On this point, Lin Zhao has already thought of a way.

Of course, in addition to using the flow rate of the river itself, some artificial dredging methods must also be strengthened.Have to find a way to use manual dredging.In this era, there are no large-scale machinery and equipment, and there are no dredging ships. It seems impossible to dredge the Yellow River entirely by manpower.

But the wisdom of the ancients should not be underestimated, they will always find a way.Maybe there were few people like this on the Yellow River before, but there must be people on the canal.Water transport on the Bianhe River was the lifeline of the Song Dynasty. Once the river silted up and affected boats, millions of people in Bianjing would starve.

Since the canal can be dredged, it seems a pity that the same method, or improved, can be used on the Yellow River.It's just that the officials of the Song Dynasty never treated the canal and the Yellow River as equals, and thought that manual dredging was still nonsense, so they didn't pay attention to this aspect.

Others don't pay attention to it, but Lin Zhao will. Any method can be tried.

So he asked Li Cheng to hire experienced workers at a high price from the Bianhe river engineering. Anyway, the Bianhe river along the river is deep and there is no need for dredging, so they are all idle.

The person Li Cheng found was Li Gongyi, a small official in the Bianhe water transport, educated and well-educated, and also an experienced river worker.At first he was willing to come because someone offered a high price, but when he saw that it was Marquis Weiyuan, he immediately panicked.As far as he is a low-level official, he is completely different from a servant of the Hou Ye.

"The villain has met Marquis Weiyuan!" For some reason, Li Gongyi couldn't help feeling a little nervous in front of Lin Zhao.

Lin Zhao waved his hand and said, "There's no need to be too polite, Mr. Li sit down!"

This young Marquis is really approachable, and Lin Zhao's kindness immediately made him feel like a spring breeze.In particular, the address of Mr. Li flattered him. He had never been so respected by a small river worker.

"Thank you, Lord!"

"Mr. Li, I think you know why you came here." Lin Zhao asked, "I heard that Mr. Li is good at dredging rivers. What's the best way?"

Reminiscent of the recent collection of river control plans by the imperial court, Li Gongyi understood everything.Although his little experience can be applied for, but he knows how much he has, who cares about being a small river worker?Even if you are lucky, you will make wedding clothes for others.Only nobles like Marquis Weiyuan can speak up.It's better to contribute indirectly and earn some rewards.

"Master Hou, the dredging of the Bianhe River is different from that of the Yellow River. The canal has a gentle flow and requires more manpower. For the Yellow River, you can borrow the water potential and use another method!"

Li Gongyi is so clear and understands his own purpose, he cut straight to the point as soon as he came up, which immediately impressed Lin Zhao.

"Sir, do you have a solution?" Lin Zhao asked immediately.

Li Gongyi said: "The river in the Sizhou section of the lower reaches of the canal is turbulent, and it is similar to the Yellow River. I have tried to use the iron-clawed Longyang mud truck!"

"Iron claw dragon?"

Li Gongyi explained: "It's like this. Use several kilograms of iron to make iron claws, and then tie ropes and hang them at the stern and sink into the bottom of the river. Then drive the boat quickly, and go down the current one after another. Repeat many times to make the river go deeper. A few feet."

After saying this, Lin Zhao understood.In fact, iron claws are used to drag along the bottom of the river, turning the deposited sediment to float up, and washing away the sediment with the help of river water flow, so as to achieve the effect of dredging.This method does not use a lot of manpower, and the equipment invested is only iron claws and boats. As for the power, it is almost all borrowed from the water potential.

It is very convenient for the boat to drag the iron claws down the river.Then flush the sand with the help of water, which is very convenient and undoubtedly the best way.

"Very good, Mr. Li really has a fantastic idea!" Lin Zhao immediately agreed, not to mention that Li Cheng found the right person. Although Li Gongyi is a small river worker, he is better at thinking and creating on weekdays.

"Master Hou is absurd!"

Lin Zhaodao: "This thing is very good. If you are willing to dedicate it to the court, I will ask for credit for you."

"Thank you, Lord Hou!" Li Gongyi was very excited. Marquis Weiyuan came forward, which was much better than writing the letter himself.

"But there is one thing, I still need to trouble Mr.!"

"But Lord Hou, please give me instructions!" Li Gongyi now treated Lin Zhao respectfully and obeyed his orders.

Lin Zhaodao: "The Yellow River is wide, and the silt deposits are serious. If it's just a few kilograms of iron claws, I'm afraid it won't work. And the silt deposits are relatively thick. If you want to dredge deeper, you need to rely on the drag force of the boats going down the river. It seems to be insufficient, and needs to be strengthened, I don’t know if there is a way, sir!”

As soon as these words came out, Li Gongyi immediately fell in admiration.It turned out that Marquis Weiyuan just wanted to take this opportunity to claim credit from the imperial court.Unexpectedly, Hou Ye knew the principle of clearing silt and sand, and he said the point as soon as he said it, he was completely an expert.In this way, I am even more admired, and the only intention to show off in my heart is gone.

"What Hou Ye said is that the small ones will improve immediately!"

Lin Zhao believes that with Li Gongyi's ability and experience, improving this is not a problem.

"Okay, then I'll have Mr. Lao. These days, I would like to ask you to live here first. When you are successful, you will have the benefits of your husband!"

Li Gongyi understood that he wanted to keep it a secret.He knew very well that this was an extremely rare opportunity, and it was only once in this lifetime, so he must not miss it, and immediately nodded in agreement.

Not to mention, Li Gongyi is really powerful, and he improved the design of the Iron Claw Dragon not long after.

"Mr. Li is so fast?" Lin Zhao was also a little surprised, such a speed is really amazing.

Li Gongyi said with a smile: "I have been busy on the river all year round, and I know all these things by heart. It only needs a little modification, and it can achieve the effect that Lord Hou requested."

"Okay, sir, please explain!"

Li Gongyi took out a sketch in his hand and explained: "In the case of Lord Hou, you can use a huge eight-foot-long tooth to make two-foot-long teeth, install them under the wood, like a loquat, and then press a stone on it. Big ropes are tied on both sides, and the two ends are connected to the big boat. The distance is about [-] steps. The ropes are twisted with pulleys, and the teeth under the giant tree are used to stir the sand. Just move the boat to achieve continuous turbulence. The effect of sand.

This method is feasible in the Yellow River.Even if the silt is quite deep, it can be stirred deeply to make the silt float and be washed away by the current.Repeated so many times, presumably it is more effective for river control.If the drinking water is too shallow and the big boat is inconvenient to move, you can use the iron claw dragon with a small boat. "

Lin Zhao immediately clapped his hands and applauded: "Sir, you really have a fantastic idea, very good, very good, this thing is really more effective. But in this way, the tackle on the boat needs manpower to control."

"There are many big-bodied people among the river workers, and it is not a problem to manipulate the pulley to twist. Besides, the dragging of the water flow will also be effective, so it is not very laborious, and it is completely feasible." Li Gongyi has experience in this regard, so he has a great say. .

"That's good, I'll let you bother me." Lin Zhao said: "Then I would like to ask you to start making immediately. As long as there is a sample, I will be of use. As for the materials, manpower, and funds needed, just ask, and it will be satisfied."

"Okay, the villain will make it as soon as possible!"

With this thing, the persuasive power in the court will definitely increase greatly. When Lin Zhao left, a confident smile appeared on the corner of his mouth.

"Li Cheng, you did a great job on this matter, you really found the right person." Lin Zhao smiled lightly and praised him repeatedly.

"Hey, it's just a blind cat meeting a dead mouse!"

"Look, don't be modest, I just wanted to praise you for your insight!"

"hey-hey!"

Not to mention, Lin Zhao was very lucky when Li Gongyi was making dredging tools.The production of cement was also completed, Yu Xuan didn't dare to delay, and immediately asked Lin Zhao to inspect it.

When Lin Zhao saw the volcanic ash-like powder, Lin Zhao praised repeatedly, it was really not easy to make this thing in ancient times.The anti-natural effect is very good.

"Master Hou, can this thing be as hard as iron in front of you?" The craftsmen were skeptical about this, but it was just a powder, how could it be possible?In particular, Lord Hou even named it cement. No matter how you hear it, you think it is a very soft thing?

"Why, trust me?"

"Small dare not!"

Lin Zhao replied with a smile: "It's not surprising that you have doubts, seeing is believing, let's try it!"

Then Lin Zhao did it himself, added water and stirred it, and it soon became a sticky mass.Lin Zhao casually used a wooden board to paste cement between two relatively smooth stones.He smiled and said, "Take a look at it in two days!"

Immediately, someone brought in some sand and stones, added cement to challenge, and poured them into a wooden barrel.The craftsmen were skeptical and said, "Just wait and see what kind of miraculous effect it will have, and you will know when the time comes."

"Really?"

Yu Xuan smiled and said: "Of course it is certain, what the Hou said could be wrong?" He has seen many inventions and inventions of Lin Zhao's whimsical ideas, so it is not surprising that he has inexplicable confidence in Lin Zhao.

"Just wait and see!" Lin Zhaolin shook his head slightly when he saw the boards used to hold the cement just now when he left. It seems that the construction tools also need to be improved, at least there should be something like a trowel.

Then he casually drew a few patterns on the white paper and handed them to Yu Xuandao: "Take it to the blacksmith shop and make some things for me!"
