.

With such strength, there are still times when one is "extremely lagging behind"?

Seeing Chen Nian's unbelievable expression, Qiu Mai nodded slightly and replied:

"Yes, otherwise what do you think?"

"I am originally engaged in machinery, so I am more concerned about this area. The last report I saw showed that more than 80% of domestic shield machines now rely on imports."

"Moreover, according to market forecasts, this number will continue to rise in the next few years, and may reach a peak in 2009, which is more than 98%."

"If that's the case, it will be really difficult for us to make a comeback."

Good guy, 98%

In essence, the entire country's TBM market is controlled by others.

Chen Nian couldn't help but frowned.

Based on historical experience, he knew that this situation was temporary.

Just like the dilemma of rare earths being controlled by the West, it is also temporary. The top management always has various ways to mobilize various resources to fight a turnaround in these key areas.

But it is undeniable that this is a "turnover" after all.

Turning over means that we have indeed been suppressed, and we have indeed lost significant benefits because of the other party's oppression.

If such a loss could be saved, how much would it be?

Chen Nian asked:

"Approximately how large is our current shield machine usage scale?"

Qiu Mai shook his head and replied:

"We don't know the scale of use, but according to predictions, by next year, we will have a demand for at least 200 units."

"If we still consider the high-speed rail project, we probably won't be able to supply even 300 units."

"At the current average import price, a shield machine costs at least 100 million yuan. Calculated in this way, the annual sales volume is about 30 billion yuan."

30000000000!

This does not seem to be a big number, but Chen Nian knows that this number is a conservative guess based on the existing situation.

After all, neither Qiu Mai nor those economists could predict the true development speed of China in the future.

By around 2008, due to the knock-on effects of the Olympic Games and other factors, a large number of developed cities began to build subways and high-speed railways were fully rolled out. Coupled with the development of certain expressways and undersea tunnel projects, the demand for this thing could be

Definitely not just 300 units.

He remembered a data: in 2020, the domestic demand for TBMs was 650 units.

Moreover, this number has declined.

In fact, the demand for TBMs has remained high since 2011. In 10 years, the internal output alone should be above 5,000.

"That's a lot of money."

Chen Nian couldn't help but sigh.

"Yeah, this thing costs money. Hey, it's built, don't you want to build a mechanical exoskeleton? This shield machine is a large mechanical exoskeleton, why don't you just do this?"

Wang Jiancheng rolled his eyes and replied:

"It's not the same thing at all, okay?"

"If we really want to build a shield machine, we might as well let the guys from the Sky Whale do it."

"The design of the cutter suction cutter unit of the Sky Whale is actually closely related to the shield machine. It is estimated that there will not be a big generation gap in technology."

"In addition, wasn't it previously advertised that the Tianjing used the ship's integrated power system? It is the same if it is directly transplanted to the shield machine."

Upon hearing this, Chen Nian's eyes lit up.

yes!

The design of the Sky Whale is really similar to the design of the large shield machine.

No, we shouldn’t say they are similar. We should say that the basic technologies they involve are actually interoperable.

In this case, if you want to build a shield machine, it shouldn't be too difficult, right?

Thinking of this, he immediately clicked on the system page in his mind.

Then, he entered an analytical entry into the system.

"Zhenxing super large shield machine."

The results were quickly fed back from the system.

[Zhenxing Super Large Shield Machine]

[Analysis requirements: 4 source points]

really!

Chen Nian's spirit was greatly boosted.

This thing is really cheap.

The 4 source points, compared to the 16 source points I have on hand, are really nothing but water——

However, Chen Nian would certainly not be so impulsive and analyze it immediately.

He must be responsible for the entire Spark team and the entire country.

The regular meeting of the Spark Team is tomorrow. At tomorrow's meeting, he can put forward his own suggestions and let other more professional people judge whether it is feasible.

Thinking of this, he picked up the chopsticks again and put a piece of mutton into his bowl.

Others also came to their senses one after another and moved their eyes from the TV to the pot.

"I hope everyone is okay."

Li Xiang sighed and said.

"It'll be fine for sure."

Chen Nian answered without thinking.

He just remembered that this accident was actually quite famous in his time.

This was a highly successful rescue under extreme conditions, and it can be regarded as one of the few advanced cases among mine and tunnel rescue cases in the world.

Based on the experience of this rescue, we actually did better than other countries in many subsequent accidents.

——

However, even so, Chen Nian still has an expectation in his heart:

I hope that such an accident will never happen again in the future
Chapter completed!
