Li Qingye did not stay at the Chad branch for too long.
The first year of Xinghe is September 20th.
Under the escort of the aerospace fleet, he arrived at the operating area of the Meroe branch. In order to avoid being too abrupt, he did not go directly to the Darfur Plateau, but went to South Meroe first.
The space carrier slowly passed over the city of Juba, the capital of South Meroe, and then landed at an airship airport on the east side.
Mapel, the manager of the Meroë branch, had been waiting at the airport for a long time.
As soon as Li Qingye stepped off the airship, he felt a heat wave: "It's really hot in this place!"
Sanchi Badaliyar quickly took a small electric fan to blow him some air.
"Chairman, welcome to Meroe Branch. I am Mapel, responsible for the company's regional operations and management." Mapel is not a pure black, but a mixed race of black and yellow from Motor Island, with a biased skin color.
to the Javanese.
Li Qingye smiled and commented: "This city is well built!"
"It is our honor to be able to catch the eye of the Chairman. Chairman, this is the industrial directory of Juba City. Please take a look."
There is a small pipe system called "capillary" in the wall of the pipe. Construction workers can inject special genetically recombinant bacteria to integrate the pipe with the underground rock soil to enhance the comprehensive load-bearing capacity of the pillar.
After the power of Homo sapiens entered here, it invested a lot of infrastructure.
Li Qingye took it and flipped through the brochure, which contained various projects and industries invested and constructed by the company in the local area.
Normally, the distance between each node will be about 10 kilometers, and the part between nodes is connected.
The motorcade drove slowly on the road.
"Chairman, we are here." Mapel said as he opened the car door.
For example, the green carpet created by genetic recombination technology covers almost the entire surface of the city's buildings, making the city of Juba look almost emerald green.
The construction process is very interesting. A biosynthetic aluminum-silicon material is first used to synthesize a hollow pipe with a diameter of 10 meters. The strength of this material is 3.27 times that of ordinary steel.
In addition to the locals, there are also many East Asians with obvious skin colors, or brown Southeast Asians, and white North Africans.
This green blanket can absorb water molecules in the air through photosynthesis. Its fleshy stems and leaves are similar to succulents and have a strong water storage capacity.
"Okay, Mr. Chairman."
On the one hand, this is because there are too many nature reserves in Africa. To build a railway on the ground, it must pass through nature reserves and wildlife habitats.
This is the product of the Meroe Air and Railway Group - the composite overhead railway.
Usually 4 to 6 hollow pipes are driven into a node.
Li Qingye could see the streets and alleys along the way through the car window.
Juba City is a highland city with an altitude of about 500 meters. The temperature is relatively mild. At least compared to other low-altitude cities in the region, it is not too hot to do outdoor activities.
After Li Qingye came down, he saw a huge factory and a large station on one side of the factory.
He closed the brochure: "Go to the Skytrain Company and have a look!"
Mapel held up a beautiful booklet with both hands.
Since the entire city is covered with a green carpet, the outdoor temperature in Juba is maintained between 20 and 35 degrees Celsius.
The reason why the Meroe Air and Railway Group came up with this kind of railway.
The construction and operation of this kind of overhead railway are somewhat different from traditional railways.
Due to gravity, small pipes will squeeze the soil and rocks in the ground pile pipes, causing the soil and rocks inside to become increasingly compact.
Of course, small pipes have limited rings, which can prevent the pipe from falling too much.
After completing the construction of the columns, the next step is also the modular node equipment, which can connect the four columns.
Due to the late-mover advantage, many of the new technologies developed by Homo Sapiens in the later stages have been reflected in the city's infrastructure construction.
Construction crews will then lay out lightweight alloy plates and rails on the cables.
However, the station is not on the ground, but in mid-air, and the tracks are also in mid-air.
After the one-time synthesis of the pipe, a construction airship modified from a transport airship was used to pull the 8,400-ton, 300-meter-long pipe into the sky.
The rails can run high-speed load-carrying railways, and suspended trains can be used below the rails to form dual-purpose rails that transport cargo above and carry passengers below.
It is a special nano-alloy that was previously used in the Dandelion project. Cables made of this alloy connect two nodes in a set of four.
Just now, Li Qingye felt a heat wave at the airport. That was because there was no large-scale green carpet in the area to regulate humidity and temperature.
The minibus took a tour around the neighborhood and then arrived at the outskirts of the XC area.
Li Qingye entered the production base.
For example, there are vast deserts, tropical rainforests that flood every three days, and a large number of uninhabited mountains and hills.
The diameter of the cable is only 3.4 cm, and its load-bearing capacity is very strong.
On the other hand, it is because Africa's infrastructure is so poor. Building surface roads and railways is not only costly, but also very troublesome.
After receiving the notice, the factory director Fan Haibo ran over sweating profusely: "Huhu... Chairman, welcome to our factory for inspection. I am Fan Haibo, the factory director."
In addition, because the material performance is good enough, four horizontal parallel rails are arranged between the two nodes, which is only the lowest utilization rate.
Specifically speaking, the material properties are great, and only with sufficient material performance support can we play this kind of overhead railway.
Under the influence of the earth's gravity, this huge pipe will instantly penetrate 240 to 280 meters underground.
The green blanket can regulate air humidity, oxygen and carbon dioxide concentration, absorb harmful gases, and maintain the indoor temperature between 26 and 28 degrees Celsius.
Moreover, each railway track can be used both up and down, which is equivalent to running 32 tracks.
Then Fan Haibo introduced the technology of their factory in detail.
Fan Haibo, who was secretly relieved, quickly replied: "Chairman, we have already constructed 86 kilometers of experimental lines, and the current operating conditions are good."
"Don't be nervous, I just took a look. I heard that you are building the Meroe Southern Plateau Railway. How is it going?"
Also use an airship to insert a smaller hollow pipe into the ground pile pipe.
Then, according to the height of the track overhead, the factory will customize a batch of hollow pipes that are smaller in diameter than the ground pile pipes and can just fit into the inner diameter of the ground pile pipes. However, these hollow pipes are sealed at both ends.
According to the conditions of the soil and rock formations below, the flight height is randomly adjusted, aimed at the target area, and then the pipe is dropped directly from a high altitude.
If the routes in this area are busy, you can also consider adding three-dimensional lines. The maximum layout is 4 floors above and below, with 4 horizontal rails on each floor, for a total of 16 rails.
For example, the Juba Dam is under construction. Juba is the core city on the upper reaches of the White Nile River. The river channel here has a very large drop, making it very suitable for dam construction.
As for the underground railway, of course the company is also working on it, but it is more wary of the super-large mantle plume and the Noumian aquifer underground in Africa, so it is more cautious about the underground railway project.
After much deliberation, Meroe Branch decided to build a lower-cost overhead railway.
Of course, this cost is for the Homo sapiens company. If it were other forces, the cost of the overhead railway would be higher than that of the ground railway.
