The reason why the Yellow River often bursts is because of the high sediment content, and the gradual siltation makes the riverbed higher and higher. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

It is a well-known fact that if the flow of water slows down, sediment is more likely to settle. After the Yellow River exits Sanmenxia, almost all the way is plain, the drop is very small, the water flow slows down, the sediment sediment is sedimented and silted, and over time, the riverbed becomes higher and higher, and even becomes an above-ground river.

Therefore, the officials of the Northern Song Dynasty all had a wish, if the water could be transported from the ground, then the flood would be alleviated. There are two ways to do this, one is to speed up the flow of water, reduce sediment sedimentation, and also to carry away the sediment that has accumulated before, so that the river channel gradually deepens.

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

Of course, in addition to using the speed of the river itself, some artificial dredging methods must also be strengthened. We have to find a way to use manual dredging. In this era, there were no large-scale machinery and equipment, no dredging ships, and it was a fantasy to completely use manpower to dredging the Yellow River.

However, the wisdom of the ancients should not be underestimated, and they will always think of a way. Maybe there were few people like this on the Yellow River before, but there will definitely be one on the canal. The transportation of the Bianhe River was the lifeblood of the Song Dynasty, once the siltation of the river affected the boating, millions of people in Bianjing would go hungry, and the consequences were unimaginable, so every year there would be river workers to dredge the canal.

Since the canal can be desilted, it seems a pity that the same method can be improved and used on the Yellow River. However, the officials of the Great Song Dynasty never treated the canal and the Yellow River equally, and thought that manual dredging was nonsense, so they did not pay attention to this aspect.

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

So he asked Li Cheng to go to the Bianhe River to hire experienced people at a high price. Anyway, the water along the river is deep, there is no need for dredging, and they are all idle.

The person Li Cheng found was called Li Gongyi, who was a small official on the Bianhe Caoyun, who had read books and was educated, and was also an experienced river worker. At first, he was willing to come because someone offered a high price, when he saw that it was the Marquis of Weiyuan. Immediately panicked. For him, a small official who is not in the stream, it is simply not the same as a marquis servant.

"The villain has seen Wei Yuanhou!" I don't know why, in front of Lin Zhao, Li Gongyi couldn't help but feel a little nervous.

Lin Zhao waved his hand and said, "No need to be polite, Mr. Li sits!" ”

This young marquis is really approachable, and Lin Zhao's kindness suddenly made him feel like a spring breeze. In particular, he was flattered by the title of Mr. Li, a river worker, who had never been so respected.

"Master Xie!"

"Mr. Lee. I think you know what you are looking for. Lin Zhao asked: "I heard that Mr. is good at river dredging, but what is the best prescription?" ”

Thinking of the recent collection of river control plans by the imperial court, Li Gongyi understood everything. Although his little experience can also be recruited, he knows how many pounds and taels he has, who cares about his little river worker? Even if there is luck. It is also a wedding garment for others. Only a noble like Marquis Wei Yuan can speak. It's better to make indirect contributions and earn some rewards.

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

Li Gongyi understood so well and understood his purpose, and as soon as he came up, he went straight to the point, which immediately impressed Lin Zhao.

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

Li Gongyi said: "The river in Sizhou downstream of the canal is turbulent, and there are similarities with the Yellow River. ”

"Ironclaw?"

Li Gongyi explained: "That's right, using a few catties of iron to make iron claws. Then tie a rope and hang it on the stern of the boat and sink to the bottom of the river. Then the boat sailed down the river and repeated. You can get the river a few feet deeper. ”

As soon as he said this, Lin Zhao understood. In fact, it is to use iron claws to drag the bottom of the river, turn the sediment to float, and wash away the sediment with the help of the river flow, so as to achieve the effect of dredging. This method does not use much manpower, and the only equipment invested is iron claws and boats, and the power is almost all borrowed from the water potential.

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

"Very good, Mr. Li really has a wonderful idea!" Lin Zhao immediately applauded, not to mention that Li Cheng was looking for the right person, although Li Gongyi was a river worker, he was better at thinking and creating on weekdays.

"Master Hou praised it falsely!"

Lin Zhao said: "This thing is very good, if Mr. is willing to dedicate it to the court, I will ask for credit for Mr." ”

"Thank you, Master Hou!" Li Gongyi was excited, and Wei Yuanhou came forward, which was much stronger than his own book.

"But there is one thing, Mr. Trouble!"

"But please ask Master Hou to command!" Li Gongyi is now respectful and respectful to Lin Zhaona, and he obeys his orders.

Lin Zhao said: "The water of the Yellow River is wide, and the sediment accumulation is also relatively serious, if it is only a few catties of iron claws, I am afraid it will not work." Moreover, the sediment accumulation is relatively thick, and the dredging is deeper, but the towing power channel of the boat that relies on the downstream seems to be insufficient, and it needs to be strengthened. ”

As soon as these words came out, Li Gongyi suddenly admired the five-body body to the ground. Originally, I thought that the Marquis of Weiyuan just wanted to use this to invite merit to the imperial court. I didn't expect Hou Ye to know the truth of dredging and sand, and he was completely an expert when he said it. In this way, the admiration is even greater, and the only remaining meaning in my heart is gone.

"What Master Hou said is that the small ones will be improved immediately!"

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

"Okay, then there is Mr. Lao, these days, please ask Mr. to live here first, and when the day of success, I will not have the benefits of Mr."

Li Gongyi understands that people want to keep it secret. He knew very well that this was an extremely rare opportunity, and it was only this time in his life, so he must not miss it, so he immediately nodded and agreed.

Not to mention, Li Gongyi is really powerful, and it didn't take long to improve the design of the Iron Claw Dragon.

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

Li Gongyi said with a smile: "I am busy on the river all year round on weekdays, and I know these things well, and I only need to modify them slightly, and I can have the effect required by the Hou Ye." ”

"Okay, please explain, sir!"

Li Gongyi took out a sketch in his hand and explained: "In the case of Master Hou, you can use a huge tooth about eight feet long, two feet long, and install it under the wood, like a loa, and then press a stone. Tie a large rope on both sides, and the two ends are linked to the big boat, about 80 steps apart, and the rope is twisted by a pulley, so that the teeth under the giant tree can stir the sediment, and the boat can be continuously turbulent by moving the boat.

This method is feasible in the Yellow River. Even if the sediment is quite deep, it can be stirred deeply, causing the sediment to float and wash away with the help of the current. This has been repeated many times, presumably to be more effective in river control. If the drinking water is too shallow and the large boat is incapacitated, you can use the Iron Claw Dragon in a small boat. ”

Lin Zhao immediately clapped his hands and applauded: "Mr. is really whimsy, very good, very good, this thing is really more effective." However, in this way, the pulley on the ship needs to be operated by manpower. ”

"There are many people with big shoulders and round waists among the river workers, and it is not a problem to control the pulley to twist. In addition, dragging the water flow will also have an effect, so it is not very laborious, and it is completely feasible. "Li Gongyi has experience in this area, so he has a lot of right to speak.

"Well, let the gentleman bother." Lin Zhao said: "Then please ask Mr. to start making it immediately, as long as a sample comes out, I will be useful." As for the materials, manpower, and funds that are needed, one should be satisfied. ”

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

With this thing, the persuasiveness in the court will inevitably increase greatly, and when he left, a confident smile appeared on the corner of Lin Zhao's mouth.

"Li Cheng, this matter is very good, I really found the right person." Lin Zhao smiled lightly and praised repeatedly.

"Hey, the blind cat just ran into a dead mouse!"

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

"Hey, hey!"

Not to mention, Lin Zhao's luck is very good, when Li Gongyi is making dredging tools here. The production of cement was also completed, Yu Xuan did not dare to delay, and immediately called Lin Zhao to inspect it.

When Lin Zhao saw the ash-like powder, Lin Zhao exclaimed, it was really not easy to make this thing in ancient times. The effect is unnatural and very good.

"Master Hou, can this thing be as hard as iron in front of it?" The craftsmen will be skeptical, but how can it be in powder form? Especially Hou Ye also named cement, how do you sound like it's a very soft thing?

"What, believe me?"

"The little ones don't dare!"

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

Then Lin Zhao took matters into his own hands, added water and stirred, and soon became a sticky mass. Lin Zhao casually used a wooden board to paste the cement between two relatively smooth stones. smiled: "You will see it in two days!" ”

Then some sand and stones were brought in, and cement was poured into a wooden barrel. The craftsmen were skeptical and said, "Just wait, and you will know what will work when the time comes." ”

"Really?"

Yu Xuan smiled: "Naturally, yes, what Hou Ye said can be wrong?" He had seen many of Lin Zhao's wonderful creations and inventions, so it was not strange at all, and he had inexplicable confidence in Lin Zhao.

"Just wait!" When Lin Zhao was leaving, he saw the wooden board used to pick up cement just now, and shook his head slightly, it seems that the construction tools also need to be improved, at least there should be something like brick knives.

Immediately, he drew a few patterns on the white paper and handed them to Yu Xuandao: "Take them to the blacksmith shop to make a few things for me!" ”
