Blue Star On December 1, 1866, in the Fujian Shipyard, the manufacturing of giant submarines entered the final stage. The craftsmen are busy nervously, and the installation of the final equipment is coming to an end.
This submarine is equipped with a three-stage power system, with a total length of 105 meters, a width of 8 meters, and an underwater displacement of up to 2,500 tons.
Sunlight shines through the high windows of the shipyard, adding a touch of brightness to the scene. The craftsmen work in division of labor. Some operate cranes to slowly install heavy equipment on the submarine, while others check the connections of pipelines and circuits to ensure that everything is in good condition. Lossless.
The last steel plate was welded on, and the body of the giant beast became more complete. The giant submarine is like a black dragon lying on the hull, waiting for its moment.
Shi Dakai visited the shipyard in person, stood next to the submarine, staring at the huge ship, his eyes flashing with excitement and expectation, feeling extremely proud of the breakthrough in national industrial technology.
As the last screw was tightened, the craftsmen burst into applause to celebrate the completion of the construction of this giant submarine. The submarine was slowly moved to the coast, preparing for the next important step - the launching ceremony.
The scene of the launching ceremony was solemn and grand. The red ribbon extends downward from the bow, symbolizing that the submarine is about to embrace the blue sea.
Accompanied by the loud military music, the national flag fluttered in the wind.
Craftsmen surrounded the submarine, and they explained to Shi Dakai the three-stage power system, powerful displacement and high-speed performance.
The design and equipment of each part have been carefully considered to ensure that the submarine can be invisible and threaten the enemy underwater.
The key moment of the launching ceremony came. A craftsman quickly cut the red ribbon on the gangway, symbolizing the beginning of the submarine's free navigation.
The huge pulley began to rotate slowly, the rope was tightened, and the submarine slowly slid into the water.
As water poured in, the submarine gradually rose and ripples spread. The entire ceremony burst into cheers and applause, and the craftsmen hugged each other excitedly, feeling the moment when this solemn and majestic giant submarine was launched into the water.
After launching, the submarine floated quietly on the blue sea. It will become the source of strength of the country's navy, carrying the mission of safeguarding national security and maintaining maritime order.
Equipped with 8 torpedo tubes and 10 cannons, it will be a nightmare for the enemy.
The giant submarine has been launched. Facing the infinite vastness of the ocean, it will become a symbol of national glory and a sharp sword to defend the country.
Yes, this submarine is the "Kunpeng" mentioned before. It is currently the largest and most advanced submarine.
Now that China's territory is large, the navy also needs to further expand its forces. Especially in the west, the military strength in the South Indian Ocean is relatively weak, and a new armored fleet needs to be built.
Blue Star On January 1, 1867, Shi Dakai convened a meeting of generals and naval experts to formulate a detailed plan to form a new armored fleet, forming a Nannan fleet with the "Kunpeng" as the main force and the "Jiaolong" and the Huaxia frigate as the supplements. Indian Ocean Fleet.
Then, the commanders of each legion issued a mobilization order, and the soldiers were called to the assembly point. They were dressed in uniforms and lined up, showing a firm will to fight.
In the military port, various ships began to gather. There are more than 200 Chinese warships of various types, including frigates, supply ships and submarines, arranged neatly like an indestructible maritime fortress.
Craftsmen are busy on the ship, installing final equipment and weapons, and they carefully integrate powerful firepower and equipment into the ship.
The solemn ceremony began. The soldiers sang military songs, the battleship's gangway was lowered, and the national flag was slowly raised at the top, revealing the majesty and strength of the country.
The commander gave the order, and one warship after another left the dock, and the fleet formed a neat formation and sailed to the newly built naval base in Jicheng (near the Maliu Strait).
Viewed from the air, a sea of metal unfolds before our eyes, with the ship's light reflected on the sea like a dazzling beam of light.
When Brother Zheng went to the West, he probably didn't have this momentum.
After several naval battles with the United States, other great powers hid when they saw China's fleet. After the South Indian Ocean Fleet was in place, China could be said to have almost controlled the South Indian Ocean.
Another major event happened in Blue Star in December 1866. Shi Dakai sent Li Hongzhang to the United States to pick up a patent at a low price. This was the "Portland cement" invented decades ago, which is Portland cement. .
Cement has not yet been used because it is not combined with steel bars, so in this era, it can be said to be of little use.
Blue Star In January 1867, with cement, sand and gravel were added to it, and some steel bars were added to make it reinforced concrete.
Shi Dakai began to invite workers to conduct experiments and build a wall with a thickness of 8cm. Workers first stabilized the concrete in the mold and then carefully placed the steel bars. When all the steel bars were placed, the workers began to fill the mold with more concrete.
Two days later, Shi Dakai brought all the senior generals to witness this historical moment. At the same time, he also had someone prepare a Mauser.
As workers slowly removed the mold from the wet concrete surface, the generals witnessed a new architectural marvel.
A towering and solid wall stood in front of the generals. It had a very smooth appearance with no obvious gaps or cracks.
"Who will use this Mauser to test the hardness of the wall I built? As long as it is penetrated, I will treat everyone to dinner tonight."
"Let me do it. I can have another meal tonight. The thickness of ordinary bricks cannot withstand this shot."
Zhu Yidian took the Mauser from Shi Dakai's hand and walked 20 meters away to aim at the wall.
boom! boom! boom!
After firing several shots in succession, the bullets got stuck in the wall, only penetrated a few centimeters, and several small fragments fell off the wall.
The generals stared in disbelief at this miracle made of reinforced concrete, shocked by this new technology. They could not imagine that such a material could be so strong and durable.
"My God, this thing is perfect for building fortifications."
All the generals applauded.
Reinforced concrete technology was officially born in China. China's infrastructure began to enter a new era, and a large number of cement plants began to appear in various cities.
The use of reinforced concrete makes buildings stronger and more durable. Traditional brick and wood structures are gradually replaced by reinforced concrete buildings, which can be used not only in the military, but also in people's livelihood.
China's city skylines are no longer limited by traditional construction techniques, and reinforced concrete has better fire resistance than traditional building materials, improving building safety.
Reinforced concrete had a profound impact on Chinese urban planning. Chinese cities began to see taller skyscrapers, giant bridges, and spacious public buildings, greatly improving the appearance and function of the city.
Urban populations are also better accommodated because high-rise buildings conserve valuable land resources.
In addition, the widespread application of reinforced concrete promoted China's industrialization and urbanization process. It provided a fast and efficient construction method, greatly shortened the construction cycle and improved the efficiency of the construction industry. The invention of reinforced concrete also promoted transportation Developments in the transport and infrastructure sectors.
Since then, China has entered a new era of large-scale infrastructure construction.
