Wang Dashan stood on the edge of the underground space and proposed: "Now that the engineer is preparing, let's go to the underground space and see what the drilling rig looks like."

Zhou Yu agreed: "Director Wang is curious about this matter, so let's go to the underground space to visit."

However, the equipment here cannot be activated, and for safety reasons, the underground space will not be entered. ”

The underground space is a huge metal house, leaving only a round hole with a diameter of 1.5 meters in the ground, which is covered with a metal cover, and there is a ladder leading to the underground space to the ground.

Zhou Yu, Jia Yun and Wang Dashan climbed down the ladder to the underground space 50 meters above the ground.

This is a space of 60 square meters, which is slightly larger than the living room.

There are two intelligent industrial robots with robotic arms.

Next to them are metal pipes with a diameter of about 20 centimeters and a length of 5 meters.

On the side of the metal pipe there is a device with a length of two meters, a diameter of 30 centimeters, and a serrated cutterhead in front.

Jia Yun said: "This is the drilling rig and the metal pipe that holds the polysilicone styrene material in place."

At the same time, he signaled to Zhou Yu that the preparation for drilling work had been completed.

Zhou Yu said to Wang Dashan: "Director Wang, our drilling work is about to begin, and we should withdraw from this underground space now."

Wang Dashan reacted and said apologetically: "I'm really sorry, it affects your work, I'll leave now."

Together, they returned to the surface and went to the command room, where the metal cover above the underground space was immediately sealed.

"Drilling begins." Zhou Yu commanded.

He and Wang Dashan came to the virtual space, where they could clearly see the entire process of drilling the ground, and the supercomputer simulated the whole process through the data fed back from the front.

Jia Yun took over the command and began to order the engineers to start the drilling program.

"Drilling starts."

Under Jia Yun's order, the intelligent industrial robot straightened the drilling rig, made it perpendicular to the ground, and after aligning the direction, it began to start the drilling rig.

The rig was like a powerful car, crashing into the earth's crust at a rapid pace, and from the tail of the rig there appeared dirt powder, which was sucked to the ground by the vacuum pipe connected to the impact.

An introduction to the drill rig also surfaced in the virtual space.

The rig is powered by superconducting cables, and it has a power of 50,000 kilowatts, which can easily crush rock and various metals.

It can excavate 100 meters per minute, and if nothing else, it can be drilled to the mantle layer in about 20 days.

The drilling rig has an intelligent maintenance function, which can be dealt with by itself if there is a small problem, and can only be scrapped when it encounters a big problem.

The cutterhead of the drilling rig is made of memory metal, which has very high wear resistance and toughness.

From the virtual space, it can be seen that the drilling rig is moving very fast, and its speed can also be seen from the impact of the ground on the mound.

Wang Dashan saw from the virtual world that 48 drilling rigs of Xinghuo Technology began to drill synchronously.

He asked with some concern: "Mr. Zhou Yu, you don't go through the reality test and directly act with 48 drilling rigs, are you sure that you will succeed?"

Zhou Yu said confidently: "After a long period of verification, our scientists have formulated more than 100 sets of plans considering tens of thousands of situations.

The drill machine will cause problems, which can be quickly eliminated and solved, and we cannot drill one well at a time, which is too troublesome and takes a long time.

We're sure we're at least halfway there, and it's well worth the fight. ”

While they were chatting, the rig had reached a depth of 500 meters.

The intelligent industrial robot takes out a closed metal pipe and puts the polysilicon styrene material in the metal pipe.

The intelligent industrial robot took out a hollow metal pipe and aimed the metal pipe at the metal pipe in front of it.

They fit together like a seamless steel pipe.

The intelligent industrial robot once again places a section of polysilicone styrene material in a metal pipe and compacts it downward.

Wang Dashan saw the action of the intelligent industrial robot, and he asked with some surprise: "Mr. Zhou Yu, didn't you directly drill the channel and then put it down into the metal pipe."

Why is it that now that you have just drilled 500 meters, you can put these metal pipes down, so that it does not affect the drilling rig to transport materials.

The metal pipe only leaves a small gap, and the rig cannot get it back after drilling the channel. ”

Zhou Yu saw that Wang Dashan was very confused, and he simply explained: "We must put down the metal pipe while excavating, otherwise this passage is too narrow and it is easy to collapse."

Drilling rigs are inherently disposable products, and once they reach the mantle layer, they are burned by hot magma.

Even if the channel does not collapse, magma upwelling will block the channel when the drilling rig reaches the mantle layer.

It is necessary to have the metal pipe follow the drilling rig, which is made of polysilicone styrene material, which can quickly export heat and maintain the temperature of the metal pipe so that it does not reach the melting point. ”

Wang Dashan suddenly realized: "It's because I didn't think it through, and it is impossible to wait for the channel to be drilled before putting down the metal pipe, after all, it is nearly 3,000 kilometers away, and no one knows what accidents will happen."

There is also the important factor of magma, and the metal pipe must closely follow the action of the drilling rig. ”

Zhou Yu stared at the position of the metal pipes probing down, and these 5-meter-long metal pipes were assembled into extremely long metal pipes.

Its hardness is very good, and the connection interface is also very stable, and it will not be crushed directly due to the squeezing caused by the collapse of the channel.

The metal tubes are connected by a strong magnetic field and can be tightly adsorbed together in a short time.

Metal tube materials have high molecular diffusion between the same materials.

While the diffusion of molecules in solid materials is very slow, liquids and gases are extremely rapid, and they can fuse together instantaneously.

However, the material that makes up the metal tube has an extremely fast molecular diffusion rate between the same materials, but it is slightly inferior to that of liquids, and it only takes more than a minute for the broken molecules to complete the diffusion and form a whole.

After Zhou Yu observed for a while, he left with Director Wang Dashan.

It is expected that it will take about 20 days to drill into the mantle layer, and when they are about to succeed, they will come to the geothermal energy base to wait for the results.

As Zhou Yu left the geothermal energy base, Jia Yun instructed the engineers to keep track of the status of the drilling rig and metal pipes.

Drilling into the earth's crust is a difficult project, and it is not easy to prepare well.

They soon encountered their first hurdle, the passage seeping water.

It is a branch of an underground river with a very high water content in the crust.

When the drilling rig crushes the rock soil, it will turn into mud and directly block the drilling rig.

Jia Yun launched many plans, but there was no obvious effect, and finally he made up his mind.

The metal pipe is pushed by the intelligent industrial robot, and the drilling rig is smashed down, directly through the mud layer.

The second obstacle is the quicksand layer, where the finely fragmented quicksand is sucked away by the drilling rig and replenished from the surrounding area.

They had to wait for time and slowly excavate in the quicksand layer.

Jia Yun has been staring at the operation of the drilling rig, constantly overcoming various difficulties encountered, he did not even go home during the Spring Festival, looking forward to the success of drilling.

Just after the Lantern Festival, Jia Yun knew that he was not far from success.

Because of the temperature fed back from the polysilicone styrene material, the front of the metal pipe is already as high as 2,000 degrees Celsius, and it can reach the mantle layer after a few kilometers of excavation.

Because of the pressure of the mantle layer, the earth's crust is also hard rock, which is the rock formation that the drilling rig likes very much, and Jia Yun knows that he has a good chance of success.
