Homo sapiens.

Chapter 470 Rage Construction
87 kilometers of overhead railway.

Along the way, 4 cities, 13 farms, and 7 mines are connected.

This kind of railway has another huge advantage, that is, the construction speed is very fast, as long as the pipelines, cables, node modules, track alloy plates, and corresponding construction airships are prepared in advance.

In the case of sufficient materials, there is no problem in laying hundreds of kilometers a month.

After all, this set of construction plans saves foundation laying, concrete pouring and maintenance, which require a relatively long process.

The core factors limiting the speed of overhead railway construction are actually the production time and scale of modular components and the number of construction airships.

At present, the Meroe Air Rail Group has a total of 37 supporting factories in the South Meroe area, with 8.7 employees and 6 construction airships.

After Fan Haibo introduced the situation, he suggested: "Chairman, a new node will be built today, and it will start in about 30 minutes. I wonder if you are interested in watching it."

"Oh? Yes." Li Qingye nodded.

"I'll arrange the train right away." Fan Haibo blushed with excitement.

Li Qingye, Mapel and his group passed the factory area, came to the elevator dedicated to passengers, took the elevator directly to the top of the station.

The station is actually the entire node. The Juba station has a maximum height of 183 meters and a track running height of 50 meters. In the area of ​​50 meters, there are special loading and unloading equipment for loading and unloading containers.

The passenger area is below the freight area, where there are several suspended passenger trains produced by the Merroy Air Rail Group itself.

"Quite spacious."

"Yes, Chairman, the gauge we use is relatively large."

Homo sapiens' railway pipe gauge is 2 meters. In order to ensure that the load railway has sufficient width, the width of the alloy plate below is 6 meters.

Therefore, the width of the carriages of the above-loaded freight trains is usually 4 to 4.2 meters.

The width of the suspended passenger train below is 6.2 meters, because the track of the suspended passenger train is essentially that layer of alloy plate.

It adopts a suspension method to ensure that the train will not fall, so the passenger train compartment must be wider than 6 meters.

The platform of the station is a fully sealed high-strength floor-to-ceiling window, which is to avoid strong winds and rainstorms.

Fan Haibo arranged a special tourist train.

"Chairman, this way please!" Fan Haibo and several security personnel entered the compartment first.
Then Li Qingye, Sanji Badalleyal, Mapel and others walked in.

Since it is a tourist model, this train is designed with two floors and only three carriages.

The upper layer of the carriage is a soft sleeper, shower room, and toilet, and the lower layer is a sightseeing restaurant.

Fan Haibo took Li Qingye directly to the sightseeing restaurant. The floor of the restaurant is made of fully transparent materials. Of course, this is one-way transparent, and the inside cannot be seen from the outside.

After a while, the train started slowly.

Compared with the commuter type passenger train, the speed of the sightseeing type is slower, about 40-120 kilometers per hour. If it is a pure commuter type, the speed can reach 80-160 kilometers.

"This train uses nuclear batteries, right?"

Fan Haibo nodded: "The chairman's eyes are like a torch. In order to increase the speed, our trains all use nuclear batteries, but they are not cobalt-60 nuclear batteries, but carbon-14 nuclear batteries."

Li Qingye immediately thought of the key point: "Is it using gold-based electric heating materials?"

"That's right, thanks to the gold mines in the Chad branch."

As for the gold mine of the Chad branch, Li Qingye just went to inspect it a few days ago.

Previously, the geological prospecting department of the company discovered several gold deposits in the volcanic area in the north of Chad, which were buried at a depth of about 450-800 meters, with reserves of thousands of tons.

Therefore, the Chad branch concentrated its efforts and mined one of the rich mines. Currently, it can produce 5 to 7 tons of gold per month.

The gold is used in the manufacture of electrothermal materials, and the Meroy Air Rail Group is only able to use gold-based electrothermal materials to generate electricity under the credit of the Chad branch.

In fact, there are a lot of gold mines in Africa, especially those veins buried below 200 meters, which are basically undeveloped.

As for the super gold mine in Antarctica, Homo sapiens is also secretly mining it. The Antarctic branch can now produce 30-40 tons of gold every month.

Of course, in order to avoid sudden changes affecting the geomagnetic field, gold mining in Antarctica only extracts gold, and there is no large-scale mining of the larger iron and nickel components.

Although the reserves of gold mines in Africa are not as good as those in Antarctica, they can also alleviate the company's huge demand for gold.

Trains that rely on their own power generation reduce the need for specialized power distribution and transmission systems.

If the traditional electrified train scheme is adopted, it is necessary to arrange cables along the line and prepare a set of special power distribution equipment.

One disadvantage of this is that once the power transmission system fails or is attacked, it may cause the entire line to be paralyzed.

The electric self-sustaining train does not have this shortcoming, and with the surging electric energy of the nuclear battery, it can further increase the speed of the train.

"How do you solve the invalid work of the nuclear battery during the rest period?"

"We use molten salt heat storage and inbound power transmission to solve the drawbacks of nuclear batteries' ineffective work."

"Molten salt heat storage? Inbound power transmission? A good idea." Li Qingye knew how they solved the problem as soon as he heard these two terms.

After half an hour.

The sightseeing train arrived at Quanshui Station, 87 kilometers away.

The construction site is 8.9 kilometers to the west of Quanshui Station, and the elevator goes up to the highest level of Quanshui Station, that is to say, the top of the sightseeing tower.

In the sightseeing room on the top of the 181-meter-high tower, there is also a long-distance telescope brought by Fan Haibo, which can see the situation 8.9 kilometers away.

"Chairman, in 5 minutes, the first ground pile hollow pipe at node 10 will be released."

at the same time.

A construction airship at the bottom of the stratosphere is hanging a huge pipeline. The construction workers are using laser positioning equipment to slowly adjust the orientation of the pipeline according to the pheromone and magnetic field anchor points marked by the spotter.

In fact, the position should not be off by tens of meters, but the construction workers who are striving for perfection are still adjusting very carefully.

He didn't press the release switch until he aimed very accurately.

In an instant, the clamps that fixed the pipeline bounced off, and the 8400-ton huge pipeline descended faster and faster. Even the strong winds in the troposphere could not change the direction of the pipeline.

The whistling sound came from a distance.

Li Qingye looked at the picture taken by the drone, and then turned his head to look at that node through the telescope.

next second.

boom!Under the support of the acceleration of gravity, the weight is instantly inserted into the fragile stratum. The pipe is inserted about 240 meters underground, and a small shock wave is triggered.

In the next half an hour, the remaining three ground pile pipes were cast down one after another, and inserted into the four predetermined positions of the nodes very precisely.

clap clap clap!
Li Qingye clapped his hands: "Yes, it seems that your technology is worthy of further promotion."

"It is our honor to be recognized by the chairman." Fan Haibo was very happy.

After all, getting Li Qingye's approval means that the overhead railway of the Merroy Air Railway Group can get the support of the head office instead of relying on the Merroy branch alone.

Li Qingye finished his investigation in Zhu Dan on the return sightseeing train after eating the local special peanut stewed beef with spinach and sorghum pancakes.

Next stop, Darfur.
