In the Port of San Francisco, super cargo ships with a displacement of more than 100,000 tons slowly entered the port.
After entering the port, a large amount of equipment began to be unloaded from the ship. Heavy trucks transported the equipment away one after another. At this moment, on a piece of land near the beach in San Francisco, the surrounding fencing has been completed.
One square kilometer of land is fenced off. This makes many people very curious. Land is also very expensive in San Francisco. Although such a large piece of land is not in the Silicon Valley of San Francisco, the price is certainly not cheap.
This piece of land is really not cheap. Zhang Fan bought it for US$2.5 billion. The price is indeed not cheap, but it is nothing to the wealthy Daqin Group.
As they drove into the base one by one, the construction workers in the base began to be busy. These construction workers were not Americans, but staff from China Longteng Group.
They came to San Francisco to work directly with a work visa. However, this visa was a short-term work visa, only for fifteen days.
This kind of visa is for technical personnel, and the work in the United States is mainly technical guidance. In fifteen days, Americans did not believe that they could do anything.
The truck unloaded the equipment, and the staff immediately began to assemble the equipment. With the help of advanced tools, they quickly assembled the equipment.
The first thing that is assembled is a very large drilling machine. The main job of the drilling machine is to drill underground. But this drilling machine is different from ordinary drilling machines.
While drilling, this drilling machine can also inject a layer of super coagulant 50 centimeters thick around it. At the same time, it has a special system inside. With this system, the time for the coagulant to dry out can be further shortened to one
minute.
The drilling machine coming this time is a large drilling machine. The diameter of drilling is ten meters. The speed of this drilling machine is drilling ten meters per hour.
For the safety of the building, this time they will drill four 120-meter-deep foundation piles at the four corners of the building. With these four foundation piles, the entire building will be as stable as a mountain even if it encounters a typhoon of level 20, and can withstand a level 9 typhoon.
There are no problems with major earthquakes.
After a whole morning, the drilling machine was installed. The huge drilling machine slowly drove to the predetermined position.
"Okay, reached the predetermined position..."
"Turn on laser positioning..."
"Satellite positioning is on..."
"The location is confirmed..."
"Turn on..."
The staff skillfully turned on the machine, and the huge drill bit started drilling directly. The pipe above the drill bit directly crushed the sediment inside and piled it far away.
The huge drill bit, like an alien tool, began to slowly drill down. The staff began to be busy, and some photographers around were also busy.
The photographers of the Longteng Group are going to record this and make it into a documentary to show the whole world the entire process of this super project. The main function is to promote the 3D construction technology of the Longteng Group.
A large amount of soil is directly discharged, while the grouting system pours a large amount of concrete made with super concrete into the channel.
A hole with a diameter of ten meters appeared on the construction site. The staff placed railings around it, the machine was working, and the command podium constantly displayed various data.
The drilling rig was busy, and the surrounding workers were also busy. They began to build a huge super printer, which was naturally completely different from an ordinary printer.
This is a specialized 3D printer, specially used to build this building. The printer consists of a bracket and a nozzle. The bracket supports the left and right sides, and the nozzle sprays super concrete concrete.
Through the control center, the nozzle sprays different amounts at various parts, thus forming a magical 3D printing.
Now this swordsmanship is printed in a square shape. There are steel supports every twenty meters. These supports are erected like tower cranes.
The steel supports form a huge steel jungle, surrounding the entire construction site in the center. This technology is not difficult, the most difficult thing is the technology of the central printer.
The scale that carries the central printer spans 540 meters. This span is very large. There is no column support in the center and it is completely integrated.
In order to create this span measurement, Longteng used the latest titanium alloy materials to make this measurement. Only then did it meet the technical requirements.
The huge central printer is like a huge steel grid. This huge grid can automatically rise, and the surrounding steel jungle is their support.
On the steel grid, there are countless smart nozzles, which can accurately spray special concrete at their own locations with an accuracy of one centimeter.
Huge structures are being built, and drilling rigs are also busy. Huge drilling rigs are busy 24 hours a day.
By noon on the third day, four huge columns had been constructed. After drilling, engineers poured special concrete directly into the drilled holes.
Four columns with a depth of 120 meters and a diameter of 10 meters were built in three days. This speed is unprecedented.
The most important thing is that it is not only fast but also of good quality. Through advanced testing equipment, the quality completely meets the standards.
The super coagulant Longteng Group has registered patents around the world and has been approved by the United States, Europe and other places. This is a new type of building material that can be used in compliance with standards.
It's just that it's more expensive to fake. For the same building, using super concrete is about 2.5 times more expensive than using ordinary reinforced concrete.
Therefore, considering economic issues, this kind of coagulant is currently of little use and is only suitable for more urgent engineering projects, unless you encounter owners such as Longteng Group and Daqin Group who are not short of money.
During these three days, the construction site was also busy. The rotary excavator continued to dig deeper into the ground. After all, there are five floors underground in this building.
These five floors have multiple functions, including intelligent underground garages, underground warehouses, equipment centers, etc.
There is also an underground shelter, which is located fifty meters underground. A drilling machine is used to dig directly to this location, and then engineering robots are used to dig out a shelter covering an area of tens of thousands of square meters.
The entire shelter can accommodate thousands of people taking refuge inside. It has a complete ecosystem inside. Even if the entrance is closed, thousands of people can live there for many years with no problem due to this ecosystem.
It only took three days for the preliminary work to be completed. During these three days, 10,000-ton cargo ships continued to dock in San Francisco, and large amounts of super coagulant and mixed powder were transported from China.
These things are purely imported from the United States. There are so many materials needed for this building, so the entire fleet has been busy in the past few days, which also made the people here curious about what is going to be built on this construction site.
