On the huge monitor, the digital models of the concrete blocks were scanned line by line.
The messy concrete fragments suddenly turned into a digital virtual three-dimensional image. This made Zhang Zhitong and the police officers widen their eyes in disbelief.
When had their technical department ever dealt with such advanced equipment?
Ten seconds later, the modeling was completed.
Just as the police were wondering what the next step would be, these messy concrete models flew up on the big screen.
"Model calculation in progress …"
"5%... 55%... 100%..."
As the progress bar moved quickly, these broken models miraculously combined together.
It was like a digital wall that had been shattered and restored. When the progress bar reached 100, the originally messy and broken virtual model had turned into a square virtual concrete wall full of cracks. The whole process took less than a minute.
The policemen's eyes widened even more. After the virtual wall was reassembled, they could clearly see an irregular deep hole the size of a potato chip bucket in the center.
Around the deep hole, there were many fragments that could not be restored. However, this did not prevent people from intuitively determining that this was a deep circular hole.
The cracks in the concrete spread out from around the deep hole in the form of a network. It was like the crack in a car window when it was hit by a bullet.
"Hiss …"
The police sucked in a breath of cold air. Could it be that this wall was shattered by armor-piercing bullets?
How big of a commotion, and how daring?
"If it was a high-speed collision, then the tunnel the criminal created in the wall should be circular. But the passage left behind at the scene is clearly a square. " A policeman in the trace inspection room expressed his opinion in a low voice. "And we did not detect any traces of gunpowder on the concrete fragments."
"It's not a high-speed collision." Ye Qing carefully looked at the restored 3D simulation and explained, "If I'm not wrong, this should be the principle of static blasting."
"It's not the kind of explosives that everyone understands. It's a mechanical explosion."
"Rocks and concrete have extremely high compressive strength on the outside, but the tensile strength on the inside is pitifully low. If the external compressive strength is 100, then the internal strength is only 2 to 10. "
"Hydraulic splitter, I don't know if anyone has seen it before?"
"For mining stones, you only need to drill a few small holes and put a splitter into the holes. In two minutes, you can break a piece of granite weighing more than a hundred tons in half from the inside."
"There is such a thing?" It was an eye-opener for Zhang Zhitong today. "So you're saying that this concrete wall was damaged by a hydraulic splitter?"
"The principle is similar, but it's not a hydraulic splitter."
"The splitter is only suitable for breaking rocks and pure concrete, but that factory building is made of reinforced concrete. As an example, this type of equipment is more widely used. "
Ye Qing took out a piece of paper and said as he drew, "After you restore the fragments collected from the scene, there must be some missing parts that have turned into dust particles."
"There should be four to eight small holes drilled around the concrete. It's just that the diameter of these small holes is too small, probably about the size of a pencil. After the explosion, the traces were covered up. "
"They should have used a more advanced hydrostatic blasting machine. The large round hole in the center was used to place the blasting machine. A few small holes were drilled around it so that the shattering of the concrete would always be within the range of the small holes. "
Every time Ye Qing said a word, the eyes of these police officers lit up a little.
"Then … is the sound of this equipment loud?" Zhang Zhitong asked excitedly.
"The sound of the blasting machine is very low. The hydraulic pump that provides hydraulic pressure to it is divided into a diesel engine and a motor. The diesel engine is louder, but if it works in a car, the sound is not a problem."
"After the reinforced concrete is broken by the pressure of the expansion from the inside, it is still connected to the steel bars. As for the steel bars inside, you have already detected that they were cut by fire cutting. Ordinary steel bars are not much stronger than cream in front of fire cutting. "
"You can go and purchase this kind of equipment and come back to simulate it."
Zhang Zhitong's beautiful eyes bloomed with indescribable joy. "Little Wang, contact the bureau immediately and ask them to purchase a hydrostatic blasting machine. The model will be bought according to the size of the round hole in the middle of the concrete after the restoration. After confirming the model, we will also visit the equipment suppliers in the city. Find out who this kind of equipment has been sold to in the past month. "
The other police officers were full of admiration and envy. So that's how it is.
They had never even heard of hydrostatic blasting machine. But after Ye Qing introduced its working principle. This group of technical police officers immediately felt a sense of enlightenment, as if they were suddenly enlightened.
"Ye Ye … Boss, I don't know where to buy this kind of software that can automatically put the broken objects back to their original state?"
"Your software is too strong. It can restore the broken concrete in a few seconds."
A male policeman wearing glasses said embarrassedly, "Our technical department often encounters criminals who smash and destroy the objects involved in the case. Sometimes it can be restored, and it can torture people to want to hit the wall. "
"It's no problem to give you the software for free."
"But …" Ye Qing's next sentence made this group of police officers want to hit the wall.
"But the software can't run on your computer. This software is the most rude and most accurate exhaustion algorithm."
"The more broken objects there are, the more hardware the exhaustion algorithm eats." Ye Qing pointed to the ground. "Under your feet, there is a super server cluster composed of tens of thousands of server units."
"The super server cluster cost billions to build. It was this super server that was calculating the software just now."
"…"
"…"
A server that cost one billion to build. Even if the Zhongyun General Administration Bureau was sold together, it would not be able to sell for so much money.
Monster Heavy Industries and Mr. Ye were really awesome, not bragging.
What else was there to say? They just honestly praised Mr. Ye in their hearts.
"If you encounter similar problems in the future, you can contact the person in charge of the laboratory." The expressions of this group of police officers made Ye Qing very happy.
"Okay, let's start the next test."
Several male police officers quickly nodded and pushed the bulky safe over like a truck.
The cover plate inside the safe door had been removed by the police, revealing the password turntable structure inside and the mechanical locking structure.
The internal gaps of the three wheel discs had overlapped, and the horizontal lever on the latch fell into the gap.
