Since it is called the artifact of the kingdom. Of course, it was very difficult to get along the way.
Today, I would like to talk about an artifact that starts from 0, goes to the mountains and cannot be exported at the end- the Tiankun.
What is the Tiankun?
Dredging.
Don't think of it as a family!
This is a dredger with skill points filled,
This is a dredging boat that breaks through the infinite blockage of technology,
This is a dredging boat that won the first place in Asia as soon as it appeared,
This is a self-propelled suction dredger independently developed by the mainland.
Maybe some knowledgeable people will issue contempt, say so much, and it is just a second-hand product.
Yes, we do not deny that it is second-hand, not only second-hand, but also bought from the Netherlands for the value of nearly 4 tons of gold, and it is a backward ship.
So what?
This ship is the epitome of the century's changes, and by transforming it, we have achieved a perfect leap forward in the technology of dredgers.
The story of Jingwei reclamation must be familiar to everyone. The significance of the Tiankun can be seen from this, and the ancient myth has been directly landed and turned into reality.
How do dredgers work?
The first step is to first go deep into the seabed and crush the sediment and rocks on the seabed.
The second step is to suck the crush into the pipe through a giant mud pump installed inside the boat.
The third step, through the powerful thrust of the pump, is transported at a speed of 6000 m³ m³ to more than 10 km away.
The three steps are repeated in a cycle, and it can dig 6000 meters³ per hour. It is a very powerful island-making artifact.
Maybe it doesn't seem like a concept to you, but let's take an example.
For example, if we want to dig a pit 1 meter deep, it only takes 1 hour to dig out the size of a football field. It's awesome.
Several of the great powers of the Celestial Dragon
First, strong working ability
Under the four powerful levels (Universal, Sand Digging, Rock Digging and Hard Rock Digging Type), any flying sand and stone can be taken down. Even the coral reef can not be eaten. True iron tooth copper tooth.
Second, there is a strong stability
The marine environment changes when it comes to change, and it is also common for winds and waves to reach level 14. So without strong stability, it's certainly not possible.
In order to ensure that the hull can always be stable, once it encounters strong winds and waves, the two 184-ton steel columns equipped with it are directly inserted into the seabed alternately, and the hull is firmly fixed in the sea.
To ensure that nothing goes wrong, the ship is also equipped with a three-cable positioning system.
The three-cable positioning system is to place three large winchs on the ship, throw the submarine anchor connected to the winch to a fixed position, fix the position through the three anchors on the seabed, and then use the cable of the three-cable winch to release the cable to realize the movement and positioning of the Tiankun. It's a bit like flying a kite.
Third, better comfort
The general dredger often has a lot of noise when working, and if it encounters solid rocks, the entire hull will shake, comparable to a "massage machine". The Tiankun, which is equipped with an aerodynamic shock absorbing device, has no such problem, and the comfortable working environment indirectly increases the efficient working time of the operator.
The role of the Celestial Carp
The inside can dredge the river channel, and the outside can build islands in the far sea.
There are many rivers and lakes in China, and once the silt accumulates, it is not only easy to cause water flooding, but also the boat trip will be blocked.
In the case of the Yangtze River, 60 million square meters of sediment sink to the bottom of the river every year. Chongming Island, the third largest island on the mainland, was built using the sediment cleared from the bottom of the Yangtze River.
Reclamation of land, not only do we have this demand, but it has obviously become a competition for countries around the world.
In small Singapore, 1/3 of the country's land area is reclaimed from the sea
Japan's Tokyo Bay has also been intensively reclaiming land.
The meaning of the Celestial Dragon
The birth of tiankun is of extraordinary significance, not only can it make great contributions to economic construction, but also can play a role in guaranteeing national defense and security. I wrote in Why is the South China Sea Stormy? Blue Whale offshore rig, witnessing china's burgeoning power" article mentioned the importance of the South China Sea.
In the past, it was often difficult to supply and the whip was out of reach, and the situation of seizing fishing boats was often powerless for island and reef encroachment.
The appearance of the Tiankun will completely and forever change this dilemma.
Through the powerful sand blowing and island filling ability of the Tiankun, one island after another is created in the South China Sea, and these islands can be turned into one warship supply point after another, which greatly strengthens the mainland's territorial defense capabilities. And these islands can also become the pillar of tourism development in the South China Sea.
From the purchase of the first dredger by the Qing government in 1902 to the completion of the dredger in 2006, witnessing the economic development of the mainland. The birth of the Tiankun in 2018 marks the commanding heights of the industry. Behind the Tiankun is a spirit of breakthrough in the blockade of science and technology. It is the hard work of countless engineers day and night that makes us no longer subject to others, and we have become a world power step by step.
