Zhuang looked at them from a short distance and nodded, but he didn't rush anyone.

The group drove directly to the construction site.

Seeing the sinking shaft, busy workers and all kinds of hoisting materials, Lao Bang stopped Zhuang not far away and said: "Owner, it's not safe down there, I'll go down and take a look." ”

"Will it work?" Zhuang asked Lao Bang not far away.

"I've just seen a lot of pictures of the EPBM, so I know what it looks like." Old Rumble.

Lee Ming-che: "......"

Seen a lot of photos? Just look at the photos to understand the shield machine? Sure enough, it's a layman!

"Director Hong, I'll take you down." The first minister hurriedly said.

The minister actually has respect for the old bangbang in his heart.

At the first sight of Lao Bang, he recognized that this was the so-called "farmer who saved people" on TV.

Farmer? Is your farmer a director?

But the director of your family can't risk his life and run to save people.

Because of this, he has more respect for Old Bang.

Only those who are on the front line of construction know how dangerous the situation will be at that time, and how powerful it is to be able to rescue people.

Lee Ming-che also put on a hard hat and followed.

I went down the engineering elevator to the bottom of the shaft, walked along the excavated tunnel, and soon saw the shield machine in front of me.

"See you at last, sweet little one!" The old man stroked the inner wall of the shield machine, affectionately like an old man who had seen his grandson.

Just now he was obsessed with looking at the various construction sites hanging in the conference room.

Almost every scene was a photo of a large group of people standing in front of a huge shield machine. Seeing it with my own eyes now is much more shocking than in the pictures.

"Little one?" Lee Ming-che looked at the huge shield machine with a diameter of more than ten meters, this behemoth as big as a tunnel would be called a "little guy"?

Kook!

Shield machine, tunnel boring machine, etc., in fact, are the same kind of construction tools, the emergence of the shield machine, can be said to be a revolution in tunnel engineering construction, but also the largest and most powerful construction machinery, the old boom obsessed with this, is not surprising.

"It's the knives that have the problem, and it's the front." Old Bang Bang looked left and right, and soon walked through the passage and came to the front of the operation room, behind the cutter head.

The Sunrians' talent for machines is unparalleled.

One of the ministers hurried to follow, and when he saw the cutterhead, the other ministers gasped.

The situation was more serious than what his subordinates reported to him, and the cutterhead in front of him was even distorted.

"There is a spherical tooth hob on the left side of the cutterhead that is damaged, and the construction personnel did not find it, and continued the construction, resulting in a scraper stuck in the rock, which distorted the drive shaft......" The construction personnel in charge of the on-site command turned pale, this is a big accident!

A shield machine is so expensive that a company like Xucheng Tunnel Construction cannot afford it, so it can only be rented.

The cutterhead, cutter, and drive are the most expensive of them.

If there is such an accident, you can't afford to pay for selling him.

"At the moment, it is only a twist, and if it is not stopped in time, it may even break ......"

The drive shaft still has a certain toughness, and a slight twist can be handled, but if it breaks......

It's a pity that now there is a huge rock stuck in the cutterhead, and the stuck angle is very tricky, no matter how you operate, it may cause the transmission shaft to break.

Lee Ming-che's brow furrowed.

It shouldn't be!

In front of the shield machine, the rock is not like tofu, but it is not much harder than foam, and the loss of the cutter head is just that, but the cutterhead is stuck and almost distorts the transmission shaft?

"Poor little one......" Old Rumble reached out and gently stroked the propeller shaft.

His eyes were slightly closed, as if he could feel the angle of the propeller shaft twisting just by using his hands.

It is said that skilled old workers can sense a trace of error with their hands, and the so-called trace is 0.01 mm.

In fact, this is beyond the limits of human touch, and they rely on experience, eyesight, judgment, and a certain peculiar intuition.

But there is no doubt that the old bang can feel more.

"This little guy has been overworked for too long." Old Rumble caressed the propeller shaft lovingly, then took another step forward and leaned in front of the cutterhead through the hole in the cutterhead.

The cutterhead was visibly tilted and slightly deformed, and he looked at the stuck part and leaned in to get in.

"Director Hong, it's dangerous inside!" A minister hurriedly grabbed the old boom, "I'll ask someone to bring tools, drill in and break the stuck rock, and stop the machine for maintenance." ”

This kind of construction space is small and the environment is dangerous, not only is it a problem of collapse, but if the rock is broken, the twisted spindle returns to the normal squeezing force, which is also fatal.

"Don't worry, I can handle it." Old Rumble nodded to the head of the department, and then took a small hammer from his pocket.

The hammer was not large and looked rusty, as if it had been idle for years.

But when I looked at the handle, I found that it was shiny and shiny, and I don't know how long it had been rubbed.

Hammer?

A small hammer not much bigger than a claw hammer?

Lao Bang carried the hammer, drilled into the back of the cutterhead, raised his hand, suddenly paused, and said to the minister: "You stay away, danger." ”

Dangerous? You say that little claw hammer is dangerous?

"Really, I don't lie to you, stay away." Old Rumble waved his hand again.

The Minister took a few steps back in a daze, and then he heard a loud bang!

It's like someone detonates an explosive, and the rocks fly!

The stones hit the cutterhead of the TBM with a clanging sound, like a messy percussion.

The next second, the propeller shaft made a slight "creaking" sound.

The deformation of the cutterhead has been restored, and the propeller shaft that was twisted and stuck has returned to normal.

The first minister was a little confused.

What the hell is that hammer? Mjolnir?

"Who's that, come and see!" A minister cautiously probed out, and Old Bang Bang saw him and beckoned him over.

Lee Ming-che also cautiously drilled through a hole in his head.

From the front, three cutter heads are damaged, one ball disc cutter is completely shattered, one wedge disc cutter is also damaged, and one scraper is even completely twisted.

Lee Ming-che is also an old engineer, and at a glance, he feels that the damage to these things is very abnormal.

The shield machine's scraper is so hard that it is impossible to twist it like a noodle.

"The records of tool changes and the maintenance of the EPB are given to me." Lee Ming-che stretched out his hand to the staff behind him, flipped it over, and suddenly his face sank like water.

"Come on, remove these three heads!" The first minister also frowned, and before he finished speaking, he saw that Lao Bang directly removed the knife from the card slot with his hands!

Tear it down!

If you didn't see it at the scene, you didn't know how shocking that scene was!

This is a shield machine, not a precision machine.

Although they are all called knives, they look completely different!

The hob is like a stone grinder with countless metal teeth on it, and when it comes to the movie, it can probably crush all the vehicles on the street to pieces.

The scraper, which is about the size of the door panel, is also a few centimeters thick at the thinnest point, which is not like a knife at all.

"Knock, knock, knock!"

In the dazzling action of the old boom, two hobs larger than tires, and a scraper the size of a door panel, were thrown to the ground with a crisp crashing sound.

The minister of the ministry looked at the old boom blankly, this thing weighs several tons, to say the least!

Then Lao Bang carried one in one hand and another under his arm, and brought the three dismantled knives back to the back of the shield machine.

I'll go, is this the rhythm of dismantling the Gundam with bare hands?

Damn! Monsters!
