Wang Dashan stood beside the underground space and proposed: "Now the engineer is preparing. Let's go to the underground space and see what the rig looks like."

Zhou Yu agreed: "Director Wang was curious about this matter, so we went to the underground space to see it.

However, the equipment here cannot be started. To ensure safety, the underground space will not be accessible. "

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

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

This is a 60-square-meter space, which is slightly larger than the living room.

There are two intelligent industrial robots with mechanical arms.

Next to them is a metal tube about 20 cm in diameter and 5 meters in length.

There is a device with a length of two meters and a diameter of 30 cm on the side of the metal pipe, with a sawtooth cutter head in front.

Jia Yun introduced: "This is the rig and the metal pipe holding the polysilicon styrene material."

At the same time he introduced to Zhou Yu, the preparation for the ground drilling work has been completed.

Zhou Yu told Wang Dashan: "Director Wang, our ground drilling is about to begin, and we should now exit this underground space."

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

They returned to the ground together and came to the command room. The metal cover above the underground space was immediately sealed.

"The ground drilling operation started." Zhou Yu commanded.

He and Wang Dashan came to the virtual space, where the entire process of drilling the ground can be clearly seen, and the supercomputer simulated the entire process through the data fed forward.

Jia Yun took command and began ordering engineers to start drilling.

"Ground drilling started."

As soon as Jia Yun ordered, the intelligent industrial robot straightened the rig so that it was perpendicular to the ground, aligned the direction, and started to start the rig.

The rig was like a powerful car that slammed into the earth's crust quickly, dirt powder appeared from the tail of the rig, and was sucked into the ground by the vacuum pipe connected by the impact.

The introduction of rigs also emerged in the virtual space.

The rig is powered by superconducting cables, and its power reaches 50,000 kilowatts, which can easily crush rocks and various metals.

It can dig up to 100 meters per minute. If there is no accident, it can be drilled into the mantle layer in about 20 days.

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

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

It can be seen from the virtual space that the speed of the drilling rig is very fast, and its speed can also be seen from the mound of impact transmitted from the ground.

Wang Dashan saw from the virtual world that Xinghuo's 48 rigs started to drill holes simultaneously.

He asked with some worries: "Mr. Zhou Yu, you have directly acted on the 48 rigs without going through the test of reality. Are you confident that you will succeed?"

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

When the rig encounters a problem, it can be quickly ruled out. It is impossible for us to drill one well at a time. This is too cumbersome and takes a long time.

We are sure that we are at least half successful, and this is already worth the effort. "

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

The intelligent industrial robot took out a closed metal tube and placed the polystyrene material in the metal tube.

The intelligent industrial robot took out a hollow metal tube and aimed the metal tube at the front metal tube.

They are tightly connected together like a seamless steel pipe.

The intelligent industrial robot once again placed a section of polystyrene material in a metal tube and compacted it down tightly.

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

Why do you just put these metal pipes down just after 500 meters of drilling? This will not affect the rig's transportation of materials.

There was only a small gap left in the metal pipe, and the rig could not get it back after drilling the tunnel. "

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

The rig is originally a disposable product. Once it drills into the mantle, it will be burned by high-temperature magma.

Even if the channel does not collapse, the magma surge will block the channel when the rig drills into the mantle.

The metal pipe must be closely followed by the drilling rig. It contains polystyrene material, which can quickly dissipate heat and maintain the temperature of the metal pipe so that it does not reach the melting point. "

Wang Dashan suddenly realized: "I didn't think about it carefully. It was impossible to wait for the tunnel to be drilled and then put down the metal pipe. After all, it was nearly 3,000 kilometers away, and no one knew what had happened.

There is also an important factor affecting the magma. The metal pipe must follow the rig closely. "

Zhou Yu stared at the location where the metal pipes went down. 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. It will not be crushed directly by the collapse of the channel.

The metal tubes are connected by a strong magnetic field, which can be tightly attached together in a short time.

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

The diffusion of molecules from solid materials is very slow, but liquids and gases are extremely fast. They can fuse together instantly.

However, the material constituting the metal tube has extremely fast molecular diffusion between the same materials, but it is slightly inferior to the liquid. It only takes more than a minute for the molecules at the fracture to complete the diffusion and form a whole.

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

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

Zhou Yu left the geothermal energy base, and Jia Yun directed the engineers to continuously track the status of the rig and metal pipes.

Crustal drilling is a difficult project, and it is not easy to prepare smoothly.

They soon encountered their first difficulty, the channel seeping.

This is an underground dark river branch, and the bottom shell is very rich in water.

The rig smashes the soil in the rock formation, which will turn into mud and directly block the rig.

Jia Yun launched a lot of preplans, but all had no obvious effect. In the end, he made up his mind.

The metal pipe was pushed by the intelligent industrial robot, and the rig slammed the rig down, directly hitting the mud layer.

The second hurdle is the quicksand layer. The fine quicksand is sucked away by the rig and replenished from the surroundings.

They can only delay time and slowly dig in the quicksand.

Jia Yun has been staring at the operation of the drilling rig, continually conquering all the difficulties encountered. He did not even go home during the Spring Festival, looking forward to the successful drilling.

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

Because of the temperature feedback from the polystyrene material, the front of the metal pipe has reached 2000 degrees Celsius, and the mantle layer can be reached within a few kilometers of the tunnel.

The crust is also a hard rock because of the pressure of the mantle layer. This is a rock layer that the rig likes very much. Jia Yun knows that he has a great chance of success.
