Looking at the ships at the scene, Daniel Zhang sighed that the power of science and technology is really powerful, and it is not difficult to salvage a sunken ship.

"It's really not that hard at this depth right now. Wei Hang nodded.

In today's society, shipwrecks occur on ships and warships sailing at sea, and there is a possibility of sinking to the bottom of the sea in the event of a shipwreck. Every year, hundreds of ships sink in the world, and from time to time there are submarine shipwrecks and planes crashing into the sea.

Some of the ships, warships, and planes sunk on the bottom of the sea contain precious cultural relics and gold and silver treasures, some contain important military secrets, and some are important secrets in their own structure.

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

As far as Wei Hang knows, the number of ancient shipwrecks in the South China Sea exceeds 2,000. Many of them have salvage value. Shipwrecks and sunken objects sink under the ocean, tens or hundreds or even thousands of meters deep.

With such a deep sea, it is very difficult to salvage smoothly, at least with the current technology. Even if it does, it will have to pay a lot of price, and the gains outweigh the losses.

"That is, at a depth of just over 100 meters, we can all go down. If it's hundreds of meters, or even thousands of meters deep, it's a bit of trouble for the robot to go down. Tang Dehui said with a smile.

"What are they going to do?" Fang Zhen found that those people had sunk iron cylinders one by one to the bottom of the sea.

"It's pontoon salvage. Wei Hang explained.

Because the pontoon salvage method is used to salvage the wreck, the water buoyancy generated is large and reliable, and the construction is convenient and safe, so the pontoon salvage method is often used to salvage the wreck.

"The principle is actually very simple, when installing the pontoon, the cylinder should be filled with water, and after the pontoon is installed around the wreck, the pontoon is filled with compressed air to discharge the water in the pontoon, and the buoyancy received by the pontoon increases. The wreck surfaced under the buoyancy of the pontoon. Wei Hang added with a smile.

In this way, they all understand the little five.

"There is still a way, in ancient times, if the ship sank, it sank, there was no way. Cao Da spoke.

"Who said that?" Wei Hang asked rhetorically.

"Uhhh

Wei Hang had to tell them that there was a character, a monk, who was the originator of salvaging the sunken ship, that was Monk Huaibing, a very powerful monk.

Moreover, Weihang found. In ancient times, Taoist priests and monks made great contributions to ancient civilization and invented many things.

It is said that the monk Huai Bing first put the sediment on the boat, and then tied one end of the rope to the boat and the other end to the boat to be salvaged, throwing the mud and sand out of the boat, and the weight of the boat was reduced. The wreck floats due to the buoyancy of the water, and the wreck comes to the surface.

"The wisdom of the ancients is still very powerful, and the story of the monk Huaibing fishing for the iron ox is probably heard by primary school students. ”

There was a pontoon bridge in the Song Dynasty. Eight iron oxen were used to hold it in place, and one iron ox weighed nearly tens of thousands of catties. During the reign of Emperor Yingzong of the Song Dynasty, the flood surged and broke the pontoon bridge, causing the iron ox to sink to the bottom of the river. Widely recruit people who can salvage iron oxen.

Monk Huaibing filled two large boats with earth and stones to sink the boat to the bottom of the water, tied the iron ox to the horizontal log between the two big boats with a rope, and hoisted the iron ox with the buoyancy of the water. Slowly removing the earth and stones from the ship, the boat surfaced, and the iron ox was salvaged. Zhang Tao reported the matter to the imperial court, and the emperor gave Monk Huaibing a purple robe.

"Ancient monks are cows!" Daniel Zhang raised his thumb.

Unlike today's monks, they all eat fat heads and big ears, eat meat and drink wine, and even pick up girls for dates, without the appearance of a monk.

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

When they looked over, they saw that there were streams of water rising from the sea, like springs. Everyone knew that the wreck was beginning to float upwards.

"It should be visible soon. "After all, it's only a hundred meters deep, and it's very fast.

But Wei Hang shook his head: "It shouldn't be completely surfaced." ”

The others were stunned for a moment, and those experts not far away looked at Wei Hang unexpectedly and said appreciatively: "That's right, Xiao Hang is very experienced! If the hull of the ship is exposed to the water, it may change when it comes into contact with sunlight and air." ”

Therefore, their plan was to pull the wreck out of the sea, but not out of the sea, and then slowly tow it back.

After getting it back, it can only be done on the shore to preserve the hull of the ship in an environment similar to that of the Crystal Palace, so as to protect the cultural relics to the greatest extent for cultural relics experts and historians to study.

In fact, it is difficult for Daniel Zhang and others to understand the so-called underwater archaeology, what is the use of pulling a sunken ship back?

"Is it worth it to spend so much money and drag a sunken ship back?" Daniel Zhang disagrees with this waste of financial resources.

In addition to excavating ancient underwater ruins, salvaging shipwrecks and underwater cultural relics, underwater archaeology also studies ancient shipbuilding, navigation, maritime communication and trade.

"That's already about archaeological value, and we don't know much about it. Wei Hang said.

"Let's go! there's nothing to do with us. "Wei Hang saw that the work was almost done.

Then, say hello to the experts and the like, and get ready to go back. This trip can be regarded as living up to the high expectations of the owner of the Deng Pavilion and solving a trouble.

After he goes back, I'm afraid that those old men will start urging him to go to sea again, which is a bit of a headache.

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

The expert was the youngest, but he was also in his forties, a middle-aged man with a Chinese face.

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

I'm familiar with these guys, and I'm a little kissed in terms of title.

"I see that you have strong salvage skills and abilities, so there is a win-win cooperation opportunity, I wonder if you are interested?" said the middle-aged man named Uncle Cai.

It turned out that they got a reliable message about a sunken ship.

However, that location is not in the country, and it is thousands of meters deep, and it is very difficult to salvage, so they are not sure at all. Therefore, the idea of Weihang was marked.

Hearing this news, Wei Hang was a little surprised, but he didn't make a fuss, after all, he had seen too many shipwrecks.

"How to cooperate with the law?" Wei Hang asked.

"As long as you salvage it, half of the treasure on it needs to be handed over to the state. However, we have to pick first, and you will take it out for auction anyway, right?"

"I have to discuss it first, after all, it's too difficult, and I'm not sure. Wei Hang didn't agree right away.

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