Looking at the ships at the scene working, Zhang Yong sighed that the power of technology is indeed powerful, and it is not difficult to salvage a wreck.

"This depth is indeed not difficult now." Wei Hang nodded.

In today's society, ships sailing at sea may occasionally have shipwreck accidents, and shipwreck accidents may sink the seabed. Every year, there are hundreds of sunk ships all over the world, and submarines may also experience shipwreck accidents and planes crash into the sea from time to time.

Some of the ships, warships and aircrafts that sunk on the seabed carry precious cultural relics and gold and silver treasures, some contain important military secrets, and some have important secrets in their own structure. Salvage of shipwrecks and sinks under the seabed is of great significance both in military and economic terms.

In addition, there are thousands of shipwrecks under the oceans around the world, and there are a large number of ancient Chinese shipwrecks under the South China Sea.

As far as Health Airlines knows, the number of ancient shipwrecks in the South China Sea is more than 2,000. Many of them have salvage value. The shipwrecks, sinks, sinks sank under the ocean, at a depth of dozens, hundreds or even thousands of meters.

In such a deep sea area, it is difficult to salvage it smoothly. At least the technology is difficult to achieve now. Even if it is done, it will have to pay a lot of money and it will not be worth the loss.

"That's right, we can all go down at a depth of only more than 100 meters. If it's a depth of hundreds of meters, or even thousands of meters, it will be a bit troublesome to go down by the robot." Tang Dehui said with a smile.

"What are they going to do?" Fang Zhen found that those people sank iron tubes into the bottom of the sea.

"This is the floating salvage method." Wei Hang explained.

Since the floating drum salvage method is used to salvage the shipwreck, the water generated by the water is large and reliable, convenient and safe, the construction is convenient and safe, so the floating drum salvage method is often used to salvage the shipwreck.

"The principle is actually very simple. When installing a float, the barrel must be filled with water. After installing the float around the wreck, the compressed air is filled into the float to discharge the water in the float. The buoyancy received by the float increases, and the shipwreck floats out of the water under the buoyancy of the float." Wei Hang added with a smile.

After saying this, Xiaowu and the others understood it instantly.

"There is still a way now. In ancient times, if the ship sinks, it will sink, and there is no way." Cao Da said.

"Who said that?" Wei Hang asked back.

"Uh! Isn't it?"

Wei Hang had to tell them a character, a monk. He was the originator of salvaging the wrecked ship, that is, Monk Huai Bing, a very powerful monk.

Moreover, Weihang discovered that in ancient times, Taoist priests, monks and others made great contributions to ancient civilizations and invented a lot of things.

I heard that monk Huai Bing first put mud and sand on the boat, then tied one end of the rope to the boat and the other end on the boat to be salvaged, throwing the mud and sand out of the boat, reducing the mass of the boat. Due to the buoyancy of the water, the wreck floated to the surface.

"The wisdom of the ancients was still very powerful. I'm afraid that elementary school students have heard of the story of monk Huai Bing taking out iron cows."

There was a floating bridge in Hezhong Prefecture in the Song Dynasty. It was fixed with eight iron cattle. One iron cattle weighed nearly tens of thousands of pounds. During the Zhiping period of Emperor Yingzong of the Song Dynasty, a flood suddenly blew the floating bridge, causing the iron cattle to sink to the bottom of the river, and widely recruited people who could salvage the iron cattle.

Monk Huai Bing used two large ships to fill the earth and rocks to sink the ship to the bottom of the water. He tied the iron cow with a rope to the crossbar between the two large ships. With the help of the buoyancy of the water, he lifted the iron cow and slowly removed the earth and rocks on the ship. The ship floated out and the iron cow was salvaged. The transport envoy Zhang Tao reported this to the court, and the emperor gave Monk Huai Bing a purple robes.

"Ancient monks were awesome!" Zhang Yong raised his thumb.

Unlike the monks today, they all eat fat and big ears. They just eat meat and drink alcohol, but they can pick up girls on dates, without the appearance of a monk at all.

"Get up." Not long after, Tang Dehui suddenly said.

When everyone looked over, they saw a stream of sea water gushing up from the sea, like a spring. Everyone knew that the wreck began to float up.

"It should be seen soon." After all, it is only a depth of about a hundred meters, very quickly.

But Weihang shook his head: "It shouldn't be completely surfaced."

The others were stunned. The experts not far away looked at Weihang unexpectedly and said with appreciation: "Yes, Xiaohang is very experienced! If the hull is exposed to the water, it may change when it comes to sunlight and air."

Therefore, their plan is to pull the wreck out of the sea bottom, but not expose it, and then slowly drag it back.

After getting it back, you can only build an environment similar to that of the Crystal Palace on the shore to preserve the hull, so that cultural relics can be protected to the greatest extent and can be studied by cultural relics experts and historians.

In fact, it is difficult for Zhang Yong and others to understand the so-called underwater archaeology. What's the use of pulling a wrecked ship back? Isn't it enough to just take away the treasures inside.

"Is it worth it to spend such a big price to drag a shipwreck back?" Zhang Yong quite disagreed with this kind of waste of financial resources.

In addition to excavating ancient underwater sites and salvaging shipwrecks and underwater cultural relics, underwater archaeology also studies ancient shipbuilding, nautical arts, maritime transportation and trade.

"That has already involved archaeological value, and we don't understand much." Wei Hang said.

"Let's go! We're nothing." Wei Hang saw that the work was almost done.

Then, he greeted the experts and others and prepared to go back. This trip was considered to be a good wish for Director Deng, and it solved a problem.

After going back, I'm afraid the old men will start urging him to go out to sea again, which is a bit of a headache.

At this time, a slightly younger expert called Weihang and said that he had something to discuss with Weihang.

That expert is the youngest, but he is also in his forties, a middle-aged man with a national face.

"Uncle Cai, what's the matter?" Wei Hang asked.

I became familiar with these guys and got a little bit of a kiss on the title.

"I saw that you have strong salvage skills and ability, so you have a win-win cooperation opportunity. I wonder if you are interested?" The middle-aged man named Uncle Cai smiled.

It turned out that they got a reliable news about a shipwreck.

However, the location was not in China, and it was thousands of meters deep, so it was very difficult to salvage, so they were not sure at all. Therefore, they came up with the idea of ​​Weihang.

When Wei Hang heard this news, he was a little surprised, but he didn't make a fuss. After all, there were too many shipwrecks he had seen.

"How to cooperate with the law?" Weihang asked.

"As long as you salvage it, you only need to hand over half of the treasures on it to the country. But we have to choose them first. Anyway, you will take them out for auction, right?"

"I have to discuss it first. After all, it is too difficult and I'm not sure." Weihang did not agree immediately.

"It's okay, you can discuss it slowly. If you are interested, you can contact Master Deng." (To be continued.)
