Previously, the Maritime Salvage Bureau had completed an equal-scale salvage test at sea using this technology in January this year.
By then, 22 giant "arc beams" will be driven by the jacking launch frame to form an arc-shaped caisson 51 meters long, 19 meters wide and 9 meters high at the bottom of the Yangtze Estuary Ancient Ship No. 2.
Only in this way can the ancient ship No. 2 at the Yangtze Estuary, as well as the thick sediment and sea water attached to it, be wrapped up "tightly".
According to estimates, including the weight of the salvage equipment, the total weight of the caisson is nearly 10,000 tons.
It was also at this time that Chen Wenzhe discovered that this seemingly simple technology was actually quite complicated.
This technology specifically combines nuclear arc beam processing technology, tunnel shield excavation technology, and immersed tube tunnel docking technology.
It also uses hydraulic synchronous lifting technology, comprehensive monitoring system, etc., which are currently the most advanced high-tech in the world.
At the same time, these technologies are also used in the fields of cultural relics protection and archaeology for the first time, truly realizing the integrated development of cultural relics protection and technological innovation.
Relying on China's high-end manufacturing capabilities, such high-tech solutions can protect the originality and integrity of underwater cultural heritage to the greatest extent and ensure the safety of cultural relics.
After the caisson was released from the water, in order to smoothly escort the ancient ship to its storage location on the Huangpu River, the Maritime Salvage Bureau also customized an engineering ship with an "opening in the middle" for the caisson.
Chen Wenzhe also has this kind of engineering ship in his fleet.
Only this kind of most professional engineering ship can allow the caisson to be tightly embedded in its open middle.
It can be said that the engineering ship in Chen Wenzhe's fleet was copied from the one owned by the Dahai City Salvage Bureau.
"It looks like they are doing it more professionally!"
Scanning around, trying to find a sunken ship, but nothing was found.
There is no other way, Chen Wenzhe can only keep adjusting his strategy and change the search terms!
Unexpectedly, such a change would not result in much gain.
At most, he changed it to the Ming Dynasty, and Dahai City became deserted.
Only then did Chen Wenzhe remember that Dahai City did not exist long and was a small fishing village before the Ming Dynasty.
In this way, he could only push the timeline to modern times. If there was no discovery in the Ming Dynasty or Qing Dynasty, what about the Republic of China?
Unexpectedly, after changing the search target to the Republic of China and antique artworks, a lot of discoveries were made.
And it was concentrated in the late period of the modern liberation war. It doesn’t take much to think about this period to know that it was the time when the Chiang Kai-shek retreated.
Unfortunately, these batches of antique cultural relics were all transported to Wanwan.
"Are there any who stayed in the country?"
He kept narrowing down the search scope, and soon, Chen Wenzhe found something.
"Qing palace bird record? I really want to hear about this thing?"
Chen Wenzhe was surprised and looked at a row of old houses on the shore.
Unexpectedly, at the end of the search, he unexpectedly discovered that someone was walking towards an old house not far away with a good thing in his hand.
The most important thing is that when I looked at the old house, I found that the man hurriedly hid a package in the wall of the old house.
And it’s an exterior wall, not hidden from the inside, but from the outside.
Update without error@
This is more interesting. How can you hide something from the outside without being discovered?
However, it seems that that thing has not been discovered.
Based on the information obtained from the traceback, Chen Wenzhe determined that the person who hid the things back then should be familiar with that house.
Otherwise, he wouldn't have hidden the things so quickly, and he still wouldn't have been discovered.
At that time, Chiang Kai-shek's leader was defeated in a roundabout way. He said he was "defeated", but in fact he also plundered a considerable amount of gold, as well as countless treasures that cannot be measured in terms of money.
Most of these treasures are now collected in the National Palace Museum in Beitai, the most famous of which is jade cabbage.
When many mainland compatriots travel to Wanwan and see these treasures, they can't help but sigh: It would be great if these treasures could stay in the mainland.
In fact, due to various reasons, some treasures did not go to Taiwan with Chiang Kai-shek, but stayed in the mainland, including many national treasure-level cultural relics.
There are many of these treasures due to their huge quantity. (This chapter is not finished yet!)
Chapter 1,394 Qing Palace Bird Spectrum
He was in a hurry and didn't take it away.
At this time, Chen Wenzhe remembered that during that period, there seemed to be a set of bird records from the Qing Palace that had not been taken away.
Fortunately, someone has now confirmed that it is a high-end imitation.
Therefore, what Chen Wenzhe sees now should be genuine.
"Stop the boat, let's go ashore here!" Chen Wenzhe said decisively.
"Boss, there is no dock!"
Gao Qijing had been standing next to Chen Wenzhe. When he heard the order, he could only say helplessly.
"Isn't it over there?" Chen Wenzhe pointed to a small pier.
"We can only stop the boat!" Gao Qijing said.
"Just go down in the boat and follow the fleet."
Chen Wenzhe had already made plans, and he didn't want to be too high-profile.
It is difficult for such a fleet to enter the port without causing a sensation!
The salvage boat slowly slowed down, and by the time Chen Wenzhe got on the boat, he already understood why people hurried ashore from the small pier here and hid their things quickly.
They obviously had a plan in advance, so everything was done in an orderly manner.
It's a pity that that person was probably taken away to Wanwan.
At that time, there was no communication between the two parties for a long time, so this person must have left and never came back.
Otherwise, a treasure would not have been hidden here for more than seventy years.
This treasure is lucky, it was secretly hidden and was not taken away.
However, when Chen Wenzhe looked back, he discovered that there were too many treasures taken away from the river during that period.
According to statistics, Chiang's leadership transported a total of 5,496 boxes of cultural relics from the Forbidden City to Wanwan, but they have not been completely inventoried until now.
If the number is too large, something will inevitably go wrong.
The person in charge of the entire cultural relic transportation at that time was named Hang Liwu. Although he had a certain level of education and had studied abroad, he was not an expert in antique research.
The reason why he is responsible for this project is because when the Japanese army invaded China, he was the person in charge of the refugee camp and was responsible for the relocation of cultural relics southward.
Therefore, he was put in charge this time just because he had experience in relocation.
But the difference from the cultural relics moving south at that time is that this time the time is more pressing and the cultural relics that need to be transported are larger.
And this time, not only did we have to transport goods, but we also had to transport people.
There are many families of Chiang Kai-shek officers, totaling hundreds of thousands of people.
There was no time for people to arrange relocation, let alone items.
In this messy situation, the clerks responsible for classification under Hang Liwu were also in a hurry.
Not all of them are antique experts, so this also causes errors to occur when making statistics. @精品/书馆·无码~~.
