The idea of the two companies is obvious, after receiving the report of the two Booths, their judgment of Huaguo is that the Chinese people are probably playing exaggerated routines, and they want to use this matter to publicize it, and their technology is definitely not so good.

When they thought that it was a large shield machine with a diameter of 20 meters, the executives of the two companies laughed, they had studied it themselves for so many years, and it had only reached about 15 meters, which was almost the technical limit, what qualifications did this small company in Huaguo have to say that they could make a large shield machine with a diameter of 20 meters?

There is no doubt about it, it must be that the Chinese people have made a big machine to put there to make a show, even if there is a certain excavation ability, but it can only be the kind of weak chicken-type machinery that I have seen before, and the excavation of the soil layer is estimated to be okay, but to excavate the hard rock layer, their technology is still not good.

So, after instructing the two for a while, the executives of both companies waited to slap the Chinese people in the face.

Booth then exclaimed, "Our TBM is hard rock, and we need to look at the rock formations here." ”

Akihito Wada also said: "Yes, if it is just an ordinary layer, it is not difficult to excavate, ordinary shield machines can do it, and we are the best shield machine, the rock layer excavated is very hard, if you want to compare, you have to use the hardest rock layer to compare! Also, if there is a hole or something in it, then it will be counted separately." ”

Geng Daming also smiled and said, "Okay, you can check it." ”

The two immediately summoned their subordinates to inspect the rock formation.

After a long while, the two looked at Geng Daming and said, "Now you can start." ”

"Even if you delay me for most of the day, I won't mind. Geng Daming said to the reporters.

An expert from China said at this time: "I think we will start the calculation from the start of the shield machine, what do you think?"

Naturally, the crowd will not have any opinions.

With the roar of the machine, I saw that the shield machine had already started construction.

Geng Daming didn't worry about anything, after all, the technology of this shield machine was not the best among all his technologies, and it was just an ordinary technology.

Those experts in China are far more worried than Geng Daming, they are more than than their eyes on the construction site, listening to the sound that is not loud, and then seeing the automatic movement of the shield machine, everyone is guessing whether this shield machine can work.

Wada Akihito was also apprehensive, and when he stepped forward to see the situation of the excavation, his face changed slightly.

As soon as the shield machine produced by Geng Daming and his team was running, they saw that the shield head kept moving forward, and a large amount of cut out gravel came out of a conveyor belt.

In just an hour, what you can see with the naked eye is a large amount of gravel transported to a car in the back, and when you look at the ore, you can see that it is completely a hard stone.

What does this mean?

Booth also understood in his heart that this showed that the other party's tunneling layer had encountered the hardest rock layer, and if it was their own shield machine, it was estimated that the speed of progress would be hindered, but looking at the situation of Geng Daming's shield machine, it was not affected much at all, and cutting rock was like cutting soil.

How is this possible!

Booth was also stunned, he never thought that Huaguo's shield machine was not a pretentious product as he imagined, but really very powerful.

Let's hope the machine has a problem after running for a while!

Akihito Wada naturally has the same psychology as him.

Unfortunately, no matter what they thought, the EPB continued to run slowly and without any problems.

In addition, the two also observed that the speed of the excavation was really fast.

That's a speed of more than one meter an hour!

After a little calculation, Wada Akihito's face became even more difficult to look at, such a tunneling speed was not comparable to their shield machine.

He even saw that the shield machine of the Chinese people seemed to be still retracting its strength, and if it let go of the speed, it was estimated that it would be faster.

Geng Daming didn't stare here, he went back to sleep by himself.

Geng Daming has also been very tired recently, but he didn't expect to be so tired from engaging in engineering.

When I woke up, it was the next day.

After eating something, Geng Daming walked towards the construction site again.

As soon as he arrived here, Huang Congping said excitedly: "Mr. Geng, it's very powerful!"

Geng Daming naturally knows that it is very powerful, at least compared to the best shield machines in the world.

"Well, nothing wronged, right?"

Huang Congping was a little speechless, this is a major matter related to the reputation of Geng Daming's machinery factory, but it seems that this Geng boss doesn't care too much.

After cleaning up his mood, Huang Congping said: "Since the construction began yesterday, most of the time has passed, and we have calculated the situation of the excavation, and it is already twenty meters!"

Without waiting for Geng Daming to speak, he continued: "The average tunneling speed is a maximum of ten meters per day, but you have now excavated twenty meters, which is twice as high as theirs!"

"I am naturally confident in the shield machine produced by my factory, and it is not very difficult to be able to dig 20 meters. Geng Daming said indifferently.

Huang Congping couldn't be indifferent, and said: "Mr. Geng, if that's the case, in one day, it's the concept of twenty-five meters, do you know what this represents? That means that the shield machine you produce is far better and more powerful than the shield machine produced by those Western countries!"

As the two spoke, they had already walked to the construction site.

When he looked at Booth again, Geng Daming found that the shield machine produced by his company could not be compared with the shield machine produced by Geng Daming and others.

How can this make you sell in China?

The two thought for a while, couldn't hold back any longer, and hurriedly went over to make a phone call, this matter is a big deal for their company, and if it is not handled well, their company may be wiped out.

"Are they all hard rock layers?" Looking at the cut out stones, Geng Daming also frowned slightly, he didn't expect to encounter such a big mountain, and there was not even a space in it.

"yes, I didn't expect to gnaw on the bones as soon as I came!"

Geng Daming checked the situation of the shield machine again, and then said with confidence: "If it is such a speed, it is estimated that the time is shorter than I said." ”
