If you want to drill a hole in a super-thick steel plate with a thickness of more than 15 cm, and the steel plate is still vertical, the easiest way is to use an armor-piercing rocket, which is definitely more reliable than any electric drill - this steel plate is not an ordinary industrial homogeneous steel plate, and the hardness is almost comparable to a drill bit!

The method of "peaceful use" of rocket drilling is not Xiang Weirong's invention, but the ingenuity and ingenuity of the technical personnel of the Huaxia scrapped weapons and ammunition destruction unit. Pen % fun % Pavilion www.biquge.info

Beginning in the early 60s, especially during the 10-year special period, China produced astronomical quantities of conventional arms and ammunition. When Xiang Weirong participated in the self-defense and counter-attack war against Vietnam, many munitions were almost reaching the limit of their shelf life, and many of them had already exceeded their scrap life, such as detonators that normally only had a shelf life of 10 years.

When teaching the Vietnamese monkeys a lesson, when the Chinese artillery was preparing for fire, they often fired shells more than three times the procedure, because those shells were almost close to their expiration date: if they were not knocked out, they would be scrapped in a year or two, and the cost would be more expensive than making new shells!

The recovery of large shells is so costly, and small things like the draw-on detonators used on grenades are even more troublesome.

Stacked together to fry in one pot?

Digging up old artillery shells from the Anti-Japanese War period can do this, but the amount of scrapped ammunition pulled out of the arsenal is too large to be so brutal: at first glance, it seems that the whole artillery shell can also recover high-quality copper materials and reduce point losses.

In fact, the problem of contamination is taken into account - if a large amount of explosives is destroyed by detonation, it will also cause serious environmental pollution.

Because there are too many of them, and there are too many copper detonators, and they need to be processed quickly, safely and efficiently, the guys in the scrapping unit came up with a solution: drill a hole in a thick steel plate, and make a small steel plate on top as a movable cover.

The person sits at this end, like a worker on an assembly line: the copper detonator is thrown into the hole, and the movable cover automatically falls under the action of gravity, and the person pulls the thread.

With a "bang", a detonator was destroyed.

Take another one from the table next to you and repeat the same action......

The speed at which the journeyman destroys the detonator is not slow, and the line in the workshop is quite spectacular - the local method, the clever method, and that's what the guys did.

Xiang Weirong had been to such a destruction unit to deliver goods, and he still felt that this method was fresh.

However, there is a problem - in order to ensure safety and save costs, the thick steel plate is made of the armor plate of the scrapped tank, which is strong!

However, it is said that a large number of people were involved in drilling holes in the top, and if they moved to a large factory to drill holes, the labor, freight and processing costs would be a large amount.

Even if you don't care about the budget, this destruction site is still relatively remote, and a large machinery factory that has not been able to move the armor plate of a tank within a radius of hundreds of kilometers cannot find the temple gate with a pig's head.

At this time, Xiang Weirong took an M72 bazooka and said, "... As a result, a technician came up with the idea of a rocket that could pierce a tank, and the scrapyard was piled up.

They dismantled the warhead of the rocket, laid the steel plate flat on the ground, fixed the armor-piercing warhead vertically at the optimal detonation height with a rebar bracket on top, and connected the fuse to the wire to detonate it electronically. This bombing is a hole, and it is said that this matter also won the third prize of the equipment department, waste utilization. ”

A group of people can be regarded as a long-term insight: drilling holes can still be drilled like this, I don't know if in more than 20 years, if any military technician dares to do this, will he be rewarded or punished?

After listening to this, Zhang Nan asked, "Shall we use the beating directly?"

Xiang Weirong nodded, "The door is vertical, you can't do it like those stupid and bold people, and it's not easy to dismantle the warhead and connect the wires." This kind of rocket theoretically has a depth of 300 millimeters for the armor penetration of vertical homogeneous steel armor, and it should not be much of a problem to deal with 200 millimeters in practice. ”

Just do it, this Randy will operate, but first the lights inside must be removed, so as not to collapse the gas waves.

A cheap miner's lamp was left at the door to illuminate it, and the others all left the tunnel, and Randy crouched down 25 meters from the door. The M72 rocket launcher could have been launched in a large room, and there was no problem in the tunnel.

But to be on the safe side, the guys helped Randy get a stainless steel table in the dining room and put it down in front of him.

In addition to the "useless" gold, the supply of materials for the little devils in the late Pacific period is tight, thinking that the dog day should not put a pile of bombs behind the blast door, and when he is ready, Randy pulls out the inner barrel of the bazooka, aiming and firing the defence.

A dull "bang" is followed by a loud bang from the tunnel almost at the same time, and Randy is soon seen running out.

The big man covered his ears, "Mr. Xiang, you should hit the bull's-eye." ”

25 meters aiming at a fixed target to launch, if this still misses, it can only be said that Randy's "seal" is estimated to be a fake and shoddy product.

It's just a small armor-piercing explosion, and there is no need to wait for a while to go in, and everyone immediately starts to get busy: racking wires for wires, and moving gas for gas welding.

As soon as he walked in, Zhang Nan felt a strange smell in the tunnel, similar to the indescribable smell of gunpowder smoke after the steel plate was cut by gas welding.

Luckily, the blower was running again, and the smell was quickly washed away.

Chen Haocha first checked the situation of the explosion-proof door, and then used a mineral water bottle to cool down the broken down position on the door, and then used a portable industrial endoscope to check the situation inside: there was no combustible material near the door inside.

The steel plate of the door is 15 centimeters thick, and it is still a little hot around the hole that has been penetrated.

Zhang Nan also leaned in to take a look: there was no imaginary piece of gold inside the door, it seemed that the space inside should be very large, and the gold was not placed near the explosion-proof door.

A few cameo gas welders began to wreak havoc, because there was already a burned-through hole, and after using equipment borrowed from the repair shop of the US military base, they were finally able to gnaw on the extra-thick blast door.

"the groove, the steel plates are so thick, these four sides are at least 40 centimeters thick, I don't know if I can open it when I go in. ”

The cutting speed was very slow, and Zhang Nan couldn't help but complain on the side.

Thomas on the side said: "As long as people can enter, this door will be easy, and it is generally not difficult to break the fast locking mechanism from the inside." ”

"That's good, otherwise if there are really thousands of tons of gold, and we dozens of people will be moved out with their arms and legs, everyone will have a short life of ten years. ”

A few idle people on the side laughed: Ten years of short life?

Luck gold, we also admit it for a short life!

Zhang Nan is really afraid of relying on manpower to transport gold, this thing is different from other things, it is really dead: as the old saying goes, a strong laborer can pick 200 catties of rice, and he can walk several miles in an hour.

If you pick 200 catties of gold, you can walk for a few miles to make people vomit blood and pick out internal injuries.

The proportion of gold is so evil.

The blast door is square and large, and the bottom opening and closing position is already parallel to the tunnel floor. But not big enough to drive directly into it, Zhang Nan guessed that the Japanese may have used a cargo-carrying battery car or a small trailer, similar to the one used to carry luggage in the airport.

Seeing that there was still no big hole that could enter for a while, Zhang Nan left the tunnel and went outside to breathe.

Chen Hao estimated that it would take at least two hours.

A few guys who can gas weld are busy inside, and those who can work harder, and those who can't hide outside the tunnel mouth to blow a cool breeze - although this is a volcano, the tunnel is still quite cool, and the wind blowing out is cool and cool.

It wasn't until 3 o'clock in the afternoon, with a heavy steel crash, that a large piece of thick steel weighing at least six or seven hundred pounds was cut, and the passage was finally opened.

Watering to cool down, Chen Hao was the first to get in.
