If you didn't know better, you'd think the suspect's family owned a switch wholesale business, and that all the switches they couldn't sell were installed on this bomb!
Furthermore, the bomb's outer shell structure is clearly a sandwich shell.
It's still the most complicated kind of sandwich crust..."
A fully functional bomb actually only has two core structural elements—
Warhead and fuse.
The warhead is a special loading device that carries explosives or increases lethality.
The fuse is the "brain" of the bomb, responsible for detonating or igniting the warhead charge.
Therefore, the simplest way to defuse a bomb is to sever the connection between the fuse and the warhead.
For a bomb with its warhead and fuse exposed, defusing it is naturally the easiest task.
To increase the difficulty of bomb disposal, bomb manufacturers often integrate the warhead and fuse into a closed structure.
For example, in this case, the bomb structure was encapsulated in a sturdy metal box.
To further increase the difficulty of bomb disposal, the metal box itself could be designed as an explosion triggering device.
The most typical example is the bomb disposal police, using the "sandwich" structure metal box mentioned earlier—
Metal – Insulating Layer – Metal!
Any drilling or cutting of this structure, which would create a connection between the inner and outer metal layers, would trigger an explosion.
The metal casing in this case uses this design.
Furthermore, the suspect went a step further in the sandwich structure.
Two armed police officers who were handling the bomb disposal had just tried to loosen the screws on the metal casing.
As a result, after turning it about 1/5 of a turn, we found that there was a problem with the resistance.
The screw appears to be connected to other parts.
This is a bomb, what else could it be connected to?
It must be the fuse inside the metal box!
The two special police officers were immediately drenched in sweat and stopped.
Fortunately, both players were skilled and had a good feel for the ball.
Otherwise, if the screw were turned any tighter, the bomb might detonate.
Those people in the mine have long since ascended to heaven.
Therefore!
The two armed police officers who handled the bomb disposal determined that the design of the bomb was completely beyond their ability to disarm it.
"If it's just this sandwich-like exterior, the messy wires, and the misleading buttons..."
The armed police officers, firing their weapons separately, spoke with hoarse voices.
"We can try to take it apart and see what happens."
Cutting wires, testing circuits—no matter what, there's always a procedure.
"But look at the size of that bomb, it's about the size of a water tank, far exceeding the size of a typical bomb."
Especially the sandwich shell, it's so neat, the seams are so precise.
It wasn't one of those crudely made homemade bombs we dealt with before.
Inside the outer shell... there's definitely a more complex structure.
The crew-cut bomb disposal officer picked up the conversation, his tone carrying an almost desperate helplessness:
"Levels, buoyancy switches, these are things that this bomb will likely use."
We even suspect that there are pressure sensors on the inner wall of the casing.
In short, there are too many ways this bomb could be detonated—
Cutting the wrong wire, moving it at too large an angle, slightly squeezing the casing, or even changes in ambient temperature...
Any of these could trigger it.
He raised his head, looking at Shen Ting, who had been listening silently not far away, and said helplessly:
"We don't even dare to touch the sandwich shell now."
They were afraid that a single mistake might disrupt the micro-balance inside the bomb, causing it to explode.
"If you don't dare touch it, then you can't defuse the bomb..."
Lin Guorui also found Shen Ting and said in a heavy tone:
"Team Leader Shen, these two are already the most skilled bomb disposal experts in our armed police force."
But the level of this bomb far exceeds their capabilities.
"Do you think we should have the investigation department send over a more senior bomb disposal expert?"
