Chapter 165 Tactical Diving Rescue
If the accounts of the three geotechnical personnel are correct, the two ministers should have been in the building at all times before the flood broke out.

Then there are only two reasons for their disappearance:
One is to be swept away by the flood while fleeing in a panic, then you have to wait for the flood to recede and look for corpses in the accumulation area downstream;

The other is to escape downwards. As a result, they were trapped in the building just like the three geotechnical personnel. From the descriptions of the three people, it is estimated that there are still many staff members in the building.

That's why Gu Jicai prepared to dive underwater for search and rescue.

But Fatima frowned.

"Vidi, even if the chief minister and accompanying secretary don't understand anything, does the minister of water conservancy not understand knowledge about evacuation and self-rescue in floods?"

"That's a possibility, and we're not all looking for two ministers."

Gu Ji shrugged his shoulders, and then directed the fleet to approach the building.

The height of the high-voltage 500KV electric pole is at least 12 meters, and three government officials hugged it, indicating that the water level has exceeded [-] meters.

In fact, the third floor of the building was indeed submerged for a small part.

In order to prevent accidents, he first tied a safety rope on his body, then replaced the rope cover on the top of the rescue telescopic rod with an iron hook, smashed the glass, and hooked it to the edge of the window frame. After confirming that it was stable, he grasped it with both hands and stepped on the wall with both feet With a push, it easily flips into the room.

This should be a leader's office, and the water probably didn't reach the calf.

Pushing open the door, Gu Ji fixed the safety rope on the fire hydrant in the corridor, and took a look at the structural diagram of the building's fire protection building. It was not until the rope was dropped that Fatima and eight or nine rescuers climbed in with the equipment on their backs.

"Fatima, take someone to see the conference room, and report any problems at any time; Singer, you guys bring your equipment and follow me to the central staircase!"

"Yes!"

Several people should drink and act in teams.

Gu Ji leaned against the wall, walked slowly to the corner, and reminded the three of Singer that the building had been submerged by the stagnant water, so on the surface, the stagnant water in the corridor and the stairwell were the same. It is flat, but if you are not careful, if you take an extra step, you will plunge into the water and hit the stairs.

"Diving suit, walkie-talkie, sonar detection."

Gu Ji waved his hand and asked the rescuers behind him to take out all the equipment.

The so-called underwater diving rescue technology means that rescuers use various scientific and technological means to first detect and determine the location of people, vehicles, and important items in the water, and then divers enter the water to salvage underwater objects and people.

Because natural waters are often not as clear as artificial swimming pools, the environment is very complicated. In addition to turbid water, there are also various undercurrents, hidden reefs, aquatic plants, cracks, etc., which can range from injuries to serious ones.

Therefore, in order to ensure safety, before underwater diving rescue, the water area must be detected first, such as ROV underwater robots, sonar detection and other sophisticated rescue equipment.

Pradhan equipped Team 14 with a multi-beam sonar detector powered by a mobile power supply, 720KHz sonar frequency, equipped with a wireless detector, built-in GPS, a wireless connection distance of 100 meters, and a scanning depth of 80 meters. rice.

Gu Ji quickly took off his waterproof rescue jacket, put on a self-contained diving suit, and put on bone conduction earphones, a safety rope, and underwater rescue tools.

On the other side, rescue technicians also finished debugging the sonar equipment.

Sonar detection is to convert electrical signals into sound signals through the transducer and emit them into the water. When the sound signal is transmitted in the water, if it encounters targets such as people falling into the water or walls, it will be reflected back and then turned into a sound signal through the transducer. electric signal.

He first connected the detector with a fishing line and lowered it bit by bit. After starting up, a horizontal scrolling pattern similar to a three-dimensional map appeared at the bottom of the color screen. The screen displayed colors such as blue, yellow, and green. The color of the wave image is reconstructed by the chip algorithm and gradually transformed into a three-dimensional image.

Gu Ji took the screen and glanced at it. The screen image was very blurry, just like a 3D modeling apprentice who just started. There are still many specks in the space, which should be mud in the water, magazines, etc. Yes, fortunately, after he had seen the building's fire-fighting architectural diagram and matched the walls one by one, he gradually got a better idea.

So put on a breathing mask and a strong flashlight.

"Get ready, three, two, one! Action!"

Whoa!

Unlike ordinary rescue divers, Gu Ji's movements in the water are very small, and even the sound is very small. After entering the water, he first feels that his body is wrapped in a warm and cool feeling. The front of the mask is cloudy, and the visibility is less than half a meter. He swings his feet lightly and continues down. At this time, his ears will feel uncomfortable like flying an airplane. This is caused by the pressure change in the ear cavity caused by water pressure. As long as he swallows more and holds his breath, he can quickly recover. ease.

As soon as he swallowed, the bone conduction headset heard the voice of the sonar inspector on the third floor:

"Be careful, there is a large object approaching to your right, the system judges it is a person!"

Due to the delay in the sonar detection, when the investigator finished speaking, a black shadow appeared in front of Gu Ji and Singer and "collided" towards them. When they got close to about half a meter, they saw A pale-skinned Indian man.

Since more than four hours have passed, his body has been swollen and deformed, especially the skin on his hands and feet is completely wrinkled and looks like a woman's skin, and his facial features are even more terrifying, with two protruding eyeballs and bulging cheeks , as if about to explode from the body.

Gu Ji had seen this kind of scene with his own eyes in the underground building checkpoint early, so he was only slightly startled, then raised his hand to push the corpse away, and then gestured to the left and right sides with a flashlight: "Singer, go to the left and focus on investigating A room with a closed door!"

"Alright, Commander!"

Singer nodded, but noticed that when Gu Ji left, his swimming movements were very slow and the amplitude was very small. He was completely using the power of his flippers to "slide" forward. He recalled when Gu Ji just entered the water. The whole process does not look like a rescue, but rather a "secret invasion".

In fact, this is Gu Ji's fighting instinct after he acquired the close-to-hand combat skills of sea operations.

In the tactical diving of special forces and special police teams, it is often necessary to perform extremely difficult tasks, such as diving penetration, underwater blasting, etc., which requires carrying a lot of professional equipment: front-mounted closed rebreather, buoyancy vest, underwater Communications, diving compasses, counterweight belts, individual sonar, and more.

The underwater speed of such a well-equipped diver is very slow, only 3-5 km/h, because long-term swimming will make people tired, and if they go too far, they will use vehicles such as underwater transport submarines, so "save energy" Very important for tactical diving.

According to the detector sonar instructions.

Gu Ji directly passed the first room, because the room with the door open means that the room has already been filled with water. Unless there is on-demand diving equipment, it is impossible to live underwater for more than four hours. Only the door is closed. It may also be like a train, barely living on the remaining air.

"Commander, the door to the fourth room on the left is closed!"

"I also found the third closed room on the right. First check the bottom door crack to see if there is any shelter. Use a flashlight or a hammer to hit the door to send a signal to the room."

As Gu Ji said, he began to approach the door frame, checking the crack of the door with a strong flashlight.

If there were people inside, they would definitely use clothes, foam and other items to find a way to plug any leaks. Sure enough, when he checked the bottom, he found that a finger-wide door gap was stuffed with plastic bags.

"Singer, I have found something here!"

After Gu Ji yelled, he knocked hard on the door. After a few times in a row, there was a sudden "dong dong dong" response from inside. At this time, Singer also swam over, "Pry open the door first."

As he spoke, he pulled out the underwater rescue tool from behind.

It is composed of a shearer, expander, supporter and high-temperature cutter, which can realize shearing, expansion, supporter, cutting and other rescue operations on land and underwater.

Gu Ji first inserted the expander into the crack of the door, twisted the lever, and with a push, the door frame holder instantly loosened.

At this time, there was a rapid and violent knock on the door in the house. Needless to say, water must have leaked in.

"Three, two, one, prepare to open the door for rescue!"

He deliberately gave a few people in the house a time to react. After giving Singer the order, the two continued to insert the demolition tool into the enlarged door crack, stepped on the wall with their right feet, and pulled it out forcefully at the same time.

Click!

A huge crack was pulled open in the upper part of the door in an instant. With Gu Ji's continuous force, the door was completely separated from the broken door frame, and all the accumulated water poured into the house, submerging the house in the blink of an eye.

"Commander! The sonar shows that there are three people in the room!"

"Singer, you take one, and give me the other two! Go back the same way, I'll go first!"

Gu Ji decisively assigned the task, and swam into the house while using a strong flashlight to attract attention. When he turned his head, he saw two black shadows approaching him. He didn't have time to pay attention to the other person, because it was Singer's task. , under the premise of not knowing the water quality of the three people and the oxygen content in their lungs, all he can do is race against time to bring them out of the water.

So Gu Ji grabbed the waist of the two of them, like carrying a chicken, swung his flippers, and quickly swam towards the central stairwell.

And the two of them seemed to understand that someone was saving them, and they hugged his waist obediently.

At this moment, it reflected the benefits of Gu Ji's previous saving of physical strength underwater, coupled with the improvement brought by the endurance mark, even with two trapped victims, his speed was still not affected.

Whoa-!
A splash of water suddenly sprang out from the stagnant water on the third floor, and Gu Ji successfully surfaced with two victims.

"Quick! Give me a hand!"

"Beware of stepping on the empty stairs!"

Seeing the rescuers rushing up, Gu Ji hurriedly took off his breathing mask and shouted, while not forgetting to pay attention to Singer who was underwater: "Singer! How is your situation over there? Answer quickly!"

"Wow! Commander, I brought the man up!"

As soon as he finished speaking, Singer and another disaster victim appeared behind him.

After the three were pulled to sit on the window sill, the accompanying medical emergency personnel rushed to check whether the three were injured, perhaps because they were trapped in the dark for four hours, which left a deep shadow on them, even if they were rescued , Several people still stared at the water on the ground with their feet shrunk.

"Don't worry, you are saved now. I will arrange for someone to send you safely to the disaster evacuation center, but I still need to ask you a few questions. Is there anyone else trapped in this building? In addition, have you Have you met the Chief and the Minister of Water Resources?"

Facing Gu Ji's question, one of the long brown-haired female government workers shook her head, took two deep breaths, suppressed the panic in her heart, and said, "There should be more than a dozen people. When we entered the building, we heard a lot of screams. When we realized that we wanted to escape, the water had reached the second floor. It was difficult to open the door. Block the door, stand on the desk and wait for rescue, as for the minister... we don't know, we only know that the chief minister is in the conference room!"

"Singer, you take the man away first, and then two divers come down with me."

"Commander, you should also take a break, after all, you swam up with two people!"

"Don't worry, this amount of work won't exhaust my energy."

Gu Ji shook his hand and put on the oxygen mask again.

Singer was panting slightly, and seeing that his breathing was indeed steady, he led the three staff members away from the window tied with safety ropes.

In this way, under Gu Ji's command.

Team 14 swept the entire building of the Geological Monitoring Bureau and rescued 11 people in total. One of them was a well-known geological survey expert in Assam. Find the figures of the two ministers.

On the other hand, Fatima searched all the rooms on the third floor of the building, including the conference room, but found no valuable clues.

"It seems that they may have been washed away by the flood. No matter, everyone leave here first and continue to the next target point..."

The minister is important, but it is impossible for Gu Ji to be around them all the time.

Just when he turned around to retreat, he happened to catch a glimpse of the geological survey expert, who seemed hesitant to speak. This guy was in his forties, with silver hair, black-rimmed glasses, dark brown skin, and white clothes. Big Gua, a typical Indian scholar dress.

During the rescue conversation, Gu Ji already knew his name.

"Professor Nandeo, do you have anything to say?"

"I……"

Nandeo hesitated for a moment, but finally made up his mind and said: "I don't know if it is appropriate to say this. Before the flood, the Chief Minister once approached me to ask about the geological activities in the Himalayas. I heard He and the minister of water conservancy seemed to have had a big fight, and the emotions on both sides were very agitated, so the accompanying secretary asked me to leave temporarily and come back later, who knows, the disaster happened right after..."

Did the two have a dispute?

Gu Ji and Fatima looked at each other, and couldn't help raising their eyebrows.
