Bring The System To Datang

Chapter 688-Where Is the Yellow River Water Transport Difficult (Fifth)

The upper reaches of the Yellow River is currently unavailable for large ships.

The boats go back and forth, and they stop at a special place, and move the goods when they need to move the goods.

It is really impassable, otherwise it is desperate.

Fishermen usually fish on the Yellow River without touching the pontoon bridge.

The upper reaches of the Yellow River, when it comes to the “ji” field, is a remote area where the Duhu Mansion and the army are stationed.

To go up from the Yellow River, you need a tracker.

The Yellow River has not been fully utilized. Otherwise, if you walk from the Yellow River and are connected by waterways, you can run to Minshan in one breath.

It was a long way from land to Yizhou.

That is to say, the shipbuilding technology of Turks and Tubo is not good. Otherwise, if people find a river, they can go directly to Chang’an.

Going from there to Chang’an is downstream, and the Yellow River has taken full advantage of it.

Datang has no ships in the past, so it would not choose to go up the Yellow River, go around a long distance, and transport things by land.

Nowadays, there are ships, and the chain-linked pontoon bridges hinder the transportation of the Yellow River when they connect the two banks.

Li Longji found a map and took a look: “The population over there is small, and the transportation of supplies has to be a few words.”

“Third brother, trade. The Yellow River has passed. It’s easy to come back. Cantaloupe, raisins, and livestock. No tracker is needed. People eat and drink on the road instead of cows and horses.”

Li Yi stroked the map with his hand.

“Hukou.” Li Longji pointed at the most critical position.

“Our boat is not big, the ship, one is to open a ditch next to it, the other is to hang a track, and sail on dry land.”

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

In the past, people used boats on dry land to solve the problem. When the boat got there, the materials on the boat were carried ashore, and the boat was also carried ashore, using rolling logs to walk around.

When you get to the other side, put down the water so that you can pass.

But you can repair the ditch, build a two-meter deep and ten-meter wide ditch, go around, and the small ship will pass.

If you have to go boating on dry land, you add tracks and rails, the boat gets stuck in place, and people pull it up.

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

It was not at that time that he needed to take a big ship, and was always thinking of ways to build it, with a large tonnage.

Li Yi thinks that it can weigh five tons as a whole, and as long as the quantity is enough for three tons, it is no problem.

“Brother, you see, it takes a long way to go from the Yellow River to the Yangtze River if Tubo wants to hit us. It takes some distance by land.

It’s really impossible to take the Yellow River. Let’s set up a point above the Hukou, or take a section of land, transport it by rail, and go to the place for loading and unloading. ”

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

Li Longji looked at it carefully, and he had to be cautious when it came to major transportation issues.

“Can the pontoon be separated?” Li Longji was active.

“Yes, the pontoons have always been built in places where the current is not very turbulent. The boat passes through, takes apart a section, then throws the rope to the opposite side, and then connects it.”

Li Yi said that the floating bridge he had used at that time can still be unhooked, but the iron cable is hanging.

It needs to be navigable, take it off, and wait for the ship to pass by at night, and then reconnect it early in the day.

It is very convenient that someone is responsible for putting the bridge back into position with ropes against the impact of the river.

“It needs a lot of money.” Li Longji talked about economic accounts again.

“Charges, the ships pay the fees, and the construction money will be paid back a little bit.”

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

People on both sides are now free to cross the pontoon bridge. In history, it is also in Li Longji’s era. The pontoon bridge with iron ropes also confiscated money.

How do people collect money when they cross the river? People have no money.

Bring a basket of eggs and sell them, but how many eggs do you have to take away?

The pontoon cannot collect money, but collect money from the ship.

Isn’t it normal to take dozens of eggs for the cost of loading a ship of eggs for sale?

Li Longji’s eyes lit up: “How much is appropriate?”

“I will build a fleet first. At least my Zhuangzi is going to set up a fleet. The court does not invest. I invest. My Zhang family fleet does not pay. I collect money for other people.”

Li Yi doesn’t know how much money should be charged. There is no artificial channel yet. It’s too early to talk about this, depending on whether the capacity is good or not.

Li Longji was tempted: “Brother Yi, you design a simple picture, send it to your brother, find someone to study, and then analyze how to operate it.”

“My design is a full set of drawings. There is nothing simple or simple. If you want to go around the Hukou Waterfall, the waterway must be curved, otherwise the drop will be too big.

In the future, we will smash down the bridge piers during the dry season and when the water is scarce, and the height from the water surface will increase, and normal medium-sized ships will be able to pass.

Then the sail is equipped with sails, and when the wind direction is good, the auxiliary ship accelerates. ”

Li Yi didn’t dare to think of a ship of several hundred tons at a time, a medium-sized ship, and the total load was 15 tons, including its own weight.

Just have a channel. Don’t underestimate the capacity of medium-sized ships. If the number is large to a certain extent, everything will be different.

Forget the goose boat, it doesn’t have enough water to go up.

Li Longji continued to look at the map: “The water flow is still too fast in some places of Brother Yi, can it be run in stages, and the upper rail is responsible for the transportation at the dock, and the boat can’t pass?”

Li Yi glanced at his third brother in surprise, okay, that’s great, he knows split shipping.

Yes, that’s right, I used to be segmented, how come the ancients were always so smart? It’s starting to be difficult to pretend to be forced.

“Third brother, when there is more iron, you can exit the waterway next to the river, then hang the buckle, the boat will go up, and use the waterwheel to rotate.”

Li Yi felt that he should still behave, and the hydraulic power is driven by the hydraulic power.

“You can make a little me in Zhuangzi first.” Li Longji didn’t quite understand, he wanted to look at the real thing.

“Well!” Li Yi agreed, and the theory was useless.

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

It is artificially flushed and placed there for people to see at a glance.

“If it is feasible, Bi Shangshu should be uncomfortable and have to spend money.” Li Longji said with a smile.

“Not the user department, I can have the money to handle this project, I can afford it.”

Li Yi didn’t care, the money matter was easy to solve.

“Then he feels even more uncomfortable. It will have nothing to do with him in the future. The money you paid.” Li Longji felt sorry for Bi Gou.

“Three brothers, if you work for another year, Lao Bi will have to leave the household department. Yao Chong should go down this year, and Zhang said and Lu Huaishen, the prime minister can’t stay in that position for too long.”

Li Yi knew that Li Longji didn’t want to stay alone in the position of prime minister.

Yao Chong is bound to go on this year. It has nothing to do with the mistakes he made. It’s time.

After going down, if you encounter problems, you will still ask Yao Chong for political advice and adopt it.

A glass of wine can release the power of soldiers, and the prime minister takes turns to do good.

Li Longji nodded slightly, he wanted to drop that way, and he did the same.

So there was the so-called Kaiyuan Prosperity, which was the prosperous age of the court, not the prosperous age of the people.
