Looking at the huge tunnel in front of him, Chengxin had a little problem.

But before he could speak, Manager Zhou seemed to see Chengxin's thoughts, and immediately spoke on the side.

"Boss Zhong, do you think the tunnel is too high?"

"Well, yes, Manager Zhou, the general tunnel is not just six or seven meters to the top."

"But this tunnel is so high, is it necessary to lay a layer of stones or something in it in the future?" Cheng Xin said, pointing to the surrounding tunnels.

"Yes, Boss Zhong, look at this outside, these gravels are all excavated by the shield machine~~"

Manager Zhou explained to Chengxin.

After Manager Zhou explained for a while, the group headed towards the depths of the tunnel.

I don't know if it's like this, or because Chengxin came to check.

Every five meters, there is a sign on the tunnel wall. It says the depth of the tunnel, five meters, ten meters, fifteen meters.

The group walked nearly 200 meters in the tunnel to see the end of the TBM.

"Boss Zhong, I didn't introduce you last time, but since I'm here this time, I'll introduce you to this big guy."

"Okay, then you can introduce me."

To be honest, it was the first time for Chengxin to get close to this big guy.

I've seen this big thing on Earth, that is, on the Internet.

I don't know if this thing is domestic or imported, and he hasn't paid attention to the heavy industry of this world.

So I don't know if this world will be like the rabbits on the earth, who can't get it out by themselves, and is asked by foreigners all over the world.

Chengxin has read a report that when the rabbit can't build a shield machine, he goes abroad to buy a shield machine.

Other foreign manufacturers directly join forces to raise prices by dozens of percent.

For example, a shield machine originally cost 100 million, and the rabbit was directly quoted 120 million, and the price was not allowed to be bargained, and it rose by 10% as soon as it was spoken.

Hey, who told us not to make it?

But then it was more relieving.

After some hard work, the shield machines of various sizes and types are 100% domestically produced.

Then there is a big price reduction, which originally cost 100 million, and directly reduced the price to 50 million, and there is also a profit.

The foreign manufacturers who originally blackmailed the rabbit were directly shut down, and then even the factory was acquired by the rabbit's domestic company.

"Boss Zhong, this shield machine is called ZT1050, with a diameter of 10.5 meters in China, and the factory price is 40 million~~."

Manager Zhou is like a salesman, and began to explain this shield machine, you said that you are a construction manager, which is not a proper job at all.

"So cheap?"

"However, if you buy a car for tens of millions, the operating cost is also relatively expensive, right? Wouldn't it be a bit expensive to dig this tunnel?"

After Manager Zhou finished speaking, Chengxin asked.

This question is a bit contradictory, do you think it is cheap but afraid of high cost?

However, this is also the reason why Chengxin does not understand the reason.

Just imagine, the tunnel outside, with a total length of 3,000 kilometers, is being constructed on both sides at the same time, although the shield machine is not half as fast as the blasting block?

In other words, the TBM can advance less than two kilometers at most.

According to the total of more than 300 million yuan in the two tunnels, the price of one meter is more than 70,000 points.

This is close to 2,000 meters, and the cost of the shield machine alone is more than 20,000 meters, not counting the cost of operation.

The operation of this shield machine is very expensive, and the electricity consumption of a day is calculated by tens of thousands of kilowatt-hours, as well as all kinds of grease and daily maintenance costs.

Not to mention that the granite is still dug here, and the money for the wear and tear of the knives every day must be a large expense, which is calculated in tens of thousands every day.

There is also the pavement after the tunnel is opened, adding pipeline lines, lighting and so on.

Together, these various costs make it possible to make no money from the tunnel built with a shield machine, but it will not make much money.

This is the reason why Chengxin thinks that the cost will not be too high.

"Hehe, it's okay, if we couldn't make it ourselves more than 20 years ago, the purchase price of a unit with such a diameter would be about 150 million."

"As for the cost, to be honest, Boss Zhong, this equipment is left over from one of our projects last year."

"This shield machine has a life span of 20,000 hours, and it took more than half of the last construction."

"By the time this tunnel is completed, the TBM will basically be scrapped."

！

！ I thought it was a new guy, but I didn't expect it to be an old one.

This may be why the second bureau gave itself a suggestion, saying that the shield machine was used to excavate outside.

As the saying goes, what you buy doesn't sell well!

After the last construction of this shield machine, it was idle by the second bureau, and there was no way, the remaining life was too short.

The other tunnel projects in the hands of the Second Bureau either do not need to be so large in diameter, or are too small, or the construction length is relatively high.

With this old one, you can't complete the task at all, and you have to order one, so you have to delay for a long time, and the gains outweigh the losses.

After receiving the tunnel project in Dashan Village, the personnel who formulated the construction plan immediately thought of this idle shield machine.

Therefore, there is this shield machine that has been put into the cold palace and is ready to be placed to sell scrap iron for a while, and there is no problem of high cost at all.

Without calculating the cost of the shield machine itself, its operating costs are much cheaper than the blasting method.

It looks like he's been pitted, but then again, this guy does dig a little faster.

Continuing to walk inside, I took a look at the structure of the shield machine, and it didn't stop until the big winch of the shield machine was approached, there was no way, there was no way ahead.

Looking at the sign not far from the side, two hundred and seventy meters, counting the head of the shield machine, two hundred and eight is about the same, and there may be more.

Therefore, the group did not stay long, returned the same way, and walked out of the tunnel.

"Boss Zhong, after reading it outside, then let's go to the mountains to have a look?"

As soon as he got out of the tunnel, Manager Zhou asked like Chengxin.

Although Chengxin doesn't think they can lie, they still have to take a look.

So Chengxin nodded and responded to Manager Zhou.

Then Cheng Xin, Manager Zhou, Director Li, and Li Gong left the other escorts who had been following, and headed towards the helicopter that had stopped not far away.

No way, this helicopter is not the kind of professional transport helicopter, so it can't pull so many people.

Under the transportation of the helicopter, Chengxin followed Manager Zhou and several people to survey the construction progress of the three places in the mountain in turn.

As from the outside, there are signs every five meters.

However, the height of the tunnels in the three places is not as large as that of the shield machine, and the width is the same, but the height is only more than seven meters.

Moreover, the walls on both sides of the tunnel are not as smooth as the shield machine, and they are relatively rough.

There is no way, this is all with a diesel rotary machine to punch holes, and then canned explosives for blasting operations.

When the granite is blasted down, forklifts and transporters are used to clean up the rubble, and finally the tunnel is repaired with a roadheader.

I have to admire these people who play with explosives, explosives are not ordinary people!

Through some calculations, you can blow up as much as you want, and you are not afraid of blowing up the tunnel.

After this round of inspection, when I returned to the project department, it was almost eleven o'clock in the morning.

"Boss Zhong, how is it, are you satisfied with the progress? It's almost noon, let's go to town for a meal, we've already booked the meal."

As soon as he returned to the project department, Manager Zhou asked.

Cheng Xin also understood the content of the other party's words, and Manager Zhou didn't say anything about the progress at all.

Instead, I'm asking Chengxin, we didn't lie about the progress, right? You see, can this project money be transferred?

"Well, okay, I'm hungry all the way."

"But Manager Zhou, let's finish the business first."

"It's only eleven o'clock, and there's still an hour before the bank closes."

"In this way, let's settle the project payment first and then eat, okay?"

Needless to say, of course Manager Zhou said that there was no problem.

Then the group didn't talk much nonsense, got into the business car of the project department, and headed towards the CCB in the town.

When they arrived in the town, the group split into two ways.

Some went to the hotel first, and only Manager Chengxin Zhou, Director Li, and a driver went to CCB.

For depositors like Chengxin, who have deposits of hundreds of millions, it goes without saying that it is definitely a VIP among the VIPs in the bank.

Although the other party didn't know, Chengxin and his party went to the CCB in the town and went directly to the lobby manager, saying that they wanted to transfer 40 million.

The other party immediately invited them into the VIP room behind the bank, and it didn't take long for the transfer to be done, and the attitude was very enthusiastic.

Chengxin collected the bank's transfer slip and the receipt issued by Director Li after receiving the transfer, and the group headed towards the hotel.
