Chapter 687: Difficulties in Yellow River Water Transport

At present, there are no large ships passing through the upper reaches of the Yellow River.

Small boats travel back and forth, and stop at special places to carry goods.

If it is really impossible to pass, they will do it at all costs.

Generally, fishermen fish in the Yellow River and do not touch the floating bridge.

The upper reaches of the Yellow River, when it reaches the "Ji" field, are remote areas, where the Protectorate and the army are stationed.

Going up the Yellow River requires boatmen.

The Yellow River has not been fully utilized, otherwise it would be possible to go to Minshan in one breath by going from the Yellow River, connected by water.

Going to Yizhou by land for a distance, it is also connected by water.

That is to say, the shipbuilding technology of the Turks and Tubo is not good, otherwise they can find a river and directly attack Chang'an.

Going to Chang'an from there is downstream, and the advantage of using the Yellow River well is great.

In the past, the Tang Dynasty did not have ships, so it would not choose to go up the Yellow River, go around, and transport things by land.

Now there are ships, and the iron chain floating bridges connecting the two banks have become an obstacle to transportation on the Yellow River.

Li Longji found a map and took a look: "There are few people there, so we have to take a long detour to transport materials."

"Third brother, trade, it's easy to go back and forth after crossing the Yellow River, cantaloupes, raisins, livestock. No need for trackers, the consumption on the road is food and drink for people, not cattle and horses."

Li Yi drew a line on the map with his hand.

"Hukou." Li Longji pointed at the most critical position.

"Our boats are not big, steamships, one is to dig a canal next to it, the other is to hang tracks, and sail on dry land."

Li Yi knew Hukou Waterfall, and it was impossible to sail there.

In the past, people used the method of sailing on dry land to solve the problem. When the boat arrived there, the materials on the boat were lifted ashore, and the boat was also lifted ashore, and rolled on logs.

When it reached the other side, water was released, so that it could pass.

But you can build a canal, build a two-meter deep and ten-meter wide canal, and go around, and the small steamer can go through.

If you must sail on dry land, add tracks, rails, and the boat is stuck in place, and people pull it up.

Livestock can also help, and the problem of Hukou Waterfall is solved.

It's not like he needed to use big ships at that time. He was always thinking of ways to build ships with large tonnage.

Li Yi thought that a total weight of five tons would be enough. Three tons would be fine as long as the quantity was sufficient.

"Third brother, look, if we transport from the Yellow River to that side, Tubo will fight us if they want to. We need to travel a long distance by land through the Han River into the Yangtze River.

If it doesn't work by going through the Yellow River, we can set up a point above Hukou, or go by land for a while, use rails for transportation, and load and unload at the place."

Li Yi drew a few more strokes on the map. The most important thing was that several floating bridges were affected.

Li Longji looked at it carefully. He had to be cautious when it came to the big issue of transportation.

"Can floating bridges be separated?" Li Longji was active.

"Yes, floating bridges have always been built in places where the water flow is not very turbulent. Small boats can pass through, dismantle a section, and then throw a rope to the other side and connect it again."

Li Yi said that the floating bridge he had at that time could also be untied, and the iron rope was hanging.

If it needs to be navigable, take it off, wait for the boat to pass at night, and connect it again in the morning.

Someone is responsible for putting the bridge back in place with ropes against the impact of the river, which is very convenient.

"It takes a lot of money." Li Longji talked about the economic account again.

"Charge, ships pay fees, and the construction money will be recovered little by little."

Li Yi has a way. This is not a question of whether he invests or not, he must follow the rules.

Now it is free for people on both sides to cross the floating bridge. In history, it was also the era of Li Longji. When using the iron chain floating bridge, no money was collected.

How to collect money from the people crossing the river? They have no money.

Bring a basket of eggs to sell, and take a few eggs from them?

You can't charge money for the floating bridge, you charge the boat.

Load a boat of eggs to sell, and take dozens of eggs as fees. Isn't it normal?

Li Longji's eyes lit up: "How much is appropriate to charge?"

"Let's talk about it first. At least my Zhuangzi is going to form a fleet. If the court doesn't invest, I will invest. My Zhang family fleet doesn't pay, and I will collect money from others."

Li Yi didn't know how much he should charge. The artificial canal hasn't been built yet. It's too early to talk about it now. It depends on whether the transportation capacity is good.

Li Longji was tempted: "Brother Yi, design a simple map and send it to me. I will find someone to study it and analyze how to operate it."

"My design is a complete set of maps. There is no such thing as simple or not. If you want to bypass Hukou Waterfall, the waterway must be curved, otherwise the drop will be too large.

In the future, when the water level is low, we will smash the bridge piers down, and the height from the water surface will be increased, so that normal medium-sized ships can pass.

Then we will equip the sails when necessary, and assist the ships to accelerate when the wind direction is good."

Li Yi didn't dare to think about ships that could carry hundreds of tons at a time. Medium-sized ships, in total, were fully loaded with 15 tons, including their own weight.

It's enough to have a canal. Don't underestimate the carrying capacity of medium-sized ships. When the number reaches a certain level, everything will be different.

Forget about goose boats, they are not strong enough to be washed by water.

Li Longji continued to look at the map: "Brother Yi, the water flow is still too fast in some places. Can we run it in sections, put it on the track and handle it at the dock, so that the boat can't pass through?"

Li Yi looked at his third brother in surprise. OK, amazing, you know how to run it in sections.

Yes, that's right, I used to have sections in my place. How come the ancients were always so smart? It's getting difficult for me to pretend to be cool.

"Third brother, after there is more iron, you can create a water channel next to the river, then hang the buckle, the boat is stuck on it, and the waterwheel is used to rotate it."

Li Yi felt that he should still show his performance and use water to drive and hang.

"You first make a small one in Zhuangzi and let me see it." Li Longji didn't quite understand. He wanted to see the real thing.

"Yeah!" Li Yi agreed. Just theory was useless.

Zhuangzi used the river to make one, and then made a small model.

The water is artificially flushed and placed there for people to see, clearly visible at a glance.

"If it is feasible, Bi Shangshu should feel uncomfortable because he has to spend money." Li Longji said with a smile.

"Without the user department, I can have the money to handle this project. I can afford it."

Li Yi didn't take it seriously. UU Reading www.uukaｎshu.net Money matters are easy to solve.

"Then it will be even more uncomfortable for him. Making money in the future has nothing to do with him, it's your money." Li Longji felt sad for Bi Gou.

"Third brother, if you work for another year, Lao Bi will have to leave the Ministry of Household Affairs. Yao Chong should go down this year, as well as Zhang Shuo and Lu Huaishen. The prime minister cannot stay in that position for too long."

Li Yi knew that Li Longji did not want a person to stay in the position of prime minister.

Yao Chong is bound to go down this year. It has nothing to do with the mistakes he made. It is because the time has come.

After going down, when encountering problems, he would still ask Yao Chong for political advice and adopt it.

A glass of wine can release military power, and the rotation of prime ministers can be a good thing.

Li Longji nodded slightly, that's what he thought and did.

Hence the so-called prosperous age of Kaiyuan. The prosperous age was the prosperous age of the imperial court, not the prosperous age of the people.
