Chapter 165 Tactical Diving Rescue

Chapter 165 Tactical Diving Rescue

If the accounts of the three geological technicians 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 floods while fleeing in a panic. In that case, the only choice is to wait for the floods to recede and search for the bodies in the downstream accumulation area;

The other was to escape downwards, but ended up trapped in the building just like the three geological technicians. And judging from the descriptions of the three people, there were probably many staff members in the building.

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

But Fatima frowned.

"Vidhi, even if the chief minister and the accompanying secretary don't understand anything, does the minister of water resources not understand flood evacuation and self-rescue and other related knowledge?"

"That's not possible, 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 telephone pole is at least 12 meters, and three government personnel are holding it on top, indicating that the water level has exceeded ten meters.

In fact, less than half of the third floor of the building was flooded.

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

This should be a leadership office, and the water is probably up to the calf.

After opening the door, Gu Ji fixed the safety rope to the fire hydrant in the corridor, and took a look at the building's fire protection structure diagram. It was not until the rope was dropped that Fatima and eight or nine rescuers climbed in one after another carrying equipment.

"Fatima, take people to see the conference room and report any problems anytime; Singh, you guys bring the equipment and follow me to the central staircase!"

"yes!"

Several people shouted and moved into groups.

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

"Wetsuit, 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 locations of people, vehicles, important items, etc. in the water, and then the 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 complex. In addition to the turbid water, there are also various undercurrents, reefs, aquatic plants, crevices, etc., which can range from injuries to getting lost and trapped.

Therefore, in order to ensure safety, before conducting underwater diving rescue, the waters must be detected first, such as ROV underwater robots, sonar detection and other high-precision rescue equipment.

Pradhan equipped the 14th detachment with a multi-beam sonar detector that uses mobile power supply, 720KHz sonar frequency, equipped with a wireless detector, built-in GPS, wireless connection distance of up to 100 meters, and scanning depth of up to 80 rice.

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

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

Sonar detection converts electrical signals into sound signals through the transducer and launches 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 sound signals through the transducer. electric signal.

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

Gu Ji took the screen and glanced at it twice. The screen was very blurry, just like a 3D modeling apprentice who had just started to do it. There were many scattered spots in the space, which should be mud in the water, magazines, etc. Fortunately, he had seen the fire protection architectural drawings of the building and mapped the walls one by one, and he gradually felt confident.

So I put on a breathing mask and a bright flashlight.

"Ready, three, two, one! Action!"

Wow!

Unlike ordinary rescue divers, Gu Ji's movement range was very small, and the sound was also very small. After entering the water, he first felt that his body was wrapped in a warm and cool feeling. The front of the mask was turbid, and the visibility was less than half a meter. He swings his feet gently and continues downward. At this time, the ears will feel uncomfortable like flying on an airplane. This is caused by the pressure change in the ear cavity caused by the water pressure. As long as you do more swallowing and breath-holding movements, you can quickly ease.

As soon as he swallowed, the voice of the sonar detector on the third floor came from the bone conduction headphones:

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

Due to a certain delay in sonar detection, when the detector finished speaking, a black shadow appeared in front of Gu Ji and Singer's eyes and "collided" towards them. When they got close to about half a meter, they saw An Indian man with pale skin.

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

Gu Ji had witnessed this kind of scene with his own eyes in the underground building level a long time ago, so he was just slightly startled, raised his hand to push the body away, and then gestured with the flashlight on the left and right sides: "Singh, go to the left and focus on the investigation. A room with a closed door!”

"Okay, Commander!"

Singer nodded, but noticed that when Gu Ji left, he swam very slowly and in a very small range. He was completely using the power of the flippers to "slide" forward. He recalled when Gu Ji entered the water just now. The whole process looked like a "secret invasion" rather than a rescue.

In fact, this is Gu Ji's combat instinct after acquiring close combat skills in maritime operations.

In the tactical diving of special forces and SWAT teams, they often need to perform extremely difficult tasks, such as diving penetration, underwater blasting, etc., which requires carrying a large amount of professional equipment: front-mounted closed rebreathers, buoyancy vests, underwater Communications, diving compasses, weight belts, individual sonar, and more.

The underwater speed of such a fully equipped diver is very slow, only 3-5 kilometers/hour, because swimming for a long time will make people tired, and if it is too far, underwater transport submarines and other vehicles will be used, so it "saves physical strength" Very important for tactical diving.

According to the detector's sonar instructions.

Gu Ji passed by the first room directly, because the room with the door open means that it has already been filled with water. Unless there is on-demand diving equipment, it is impossible to survive underwater for more than four hours. Only the door is closed. The room may be like a train, barely surviving 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. I first checked the bottom door seam to see if there was any obstruction. Then I used a flashlight or hammer to hit the door to send a signal to the house."

As Gu Ji said this, he began to approach the door frame and inspect the cracks in the door with a strong flashlight.

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

"Singh, I've discovered something here!"

After Gu Ji shouted, he knocked hard on the door. After several consecutive knocks, there was a sudden "dong dong dong" response from inside. At this time, Singer also swam over and said, "Pry the door open first."

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

It is composed of shears, expanders, pushers and high-temperature cutters, and can carry out shearing, expansion, push-up, cutting and other demolition operations on land and underwater.

Gu Ji first inserted the expander into the crack of the door, twisted the lever, and with a little force, the door frame retainer became loose instantly.

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

"Three, two, one, prepare to tear down the door and rescue!"

He deliberately gave several people in the room time to react. After giving the order to Singer, the two of them continued to insert the demolition tools deep into the enlarged crack in the door, stepped on the wall with their right feet, and pulled outwards with force at the same time.

Click!

A huge crack opened in the upper part of the door in an instant. As Gu Ji continued to exert force, the door was completely separated from the broken door frame, and all the water poured into the house, flooding the house in the blink of an eye.

"Commander! Sonar shows there are three people in the room!"

"Singh, take one with you and leave the other two to me! Return 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 people. When he turned his head, he saw two black figures approaching him. He had no time to pay attention to the other person because that was Singer's task. , without knowing the water quality of the three people and the oxygen content in their lungs, all he could do was race against time to bring them out of the water.

So Gu Ji grabbed the waists of the two of them, like carrying chickens, swayed his flippers, and quickly swam towards the central stairwell.

The two of them seemed to understand that someone was saving them, and they held his waist honestly.

At this moment, Gu Ji's benefit of saving energy underwater was reflected. Coupled with the improvement brought by the endurance mark, his speed was not affected at all even if he was carrying two trapped victims.

Wow——!

A splash of water suddenly burst out of the water on the third floor, and Gu Ji successfully surfaced with two victims.

"Quick! Help me!"

"Be careful of missing the stairs!"

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

"Wow! Commander, I brought people up!"

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

After the three people were pulled to the window sill and sat down, the accompanying medical emergency personnel hurriedly checked whether the three people were injured. Perhaps it was the four hours of being trapped in the dark that left a deep shadow on them. Even if they were rescued, , several people still stared, shrank their feet, looking at the water on the ground in horror.

"Don't worry, you have been rescued 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, are you there?" Have you met the chief minister and the two ministers of Water Resources?"

Facing Gu Ji's question, one of the female government workers with long brown hair shook her head, took two deep breaths, suppressed the panic in her heart and said: "There should be more than a dozen people. They were filled in soon after the flood." When we entered the building, we heard a lot of screams. By the time we reacted and wanted to escape, the water had already reached the second floor. It was difficult to open the door. Water kept pouring in from the cracks in the door. In desperation, we could only Block the crack in the door and stand on the desk waiting for rescue. As for the minister... we don’t know, we only know that the chief minister is in the conference room!”

"Singh, you take the people away first, and then two divers will come down with me."

"Commander, you should also take a rest. After all, you swam up here with two people!"

"Don't worry, this little workload won't drain my energy."

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

Singer panted slightly, and seeing that his breathing was indeed steady, he led the three staff members and left through the window tied with a safety rope.

Just like that, under Gu Ji's command.

Team 14 swept the entire Geological Monitoring Bureau building and rescued a total of 11 people. One of them was a well-known geological survey expert in Assam. The only regret was that there were no trapped people or bodies floating in the water. Find the two ministers.

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 what, everyone leaves here first and continues to the next target point..."

The minister was important, but it was impossible for Gu to hang around them all the time.

Just as he turned around to retreat, he accidentally caught a glimpse of the geological survey expert, who seemed to be hesitant to speak. This guy was in his forties, with silver hair, black-rimmed glasses, dark brown skin, and a white suit. Da Gua, a typical Indian scholar's 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 whether it is appropriate to say this. Before the flood, the chief minister once approached me to ask about the geological activities in the Himalayas. At that time, I heard outside the door He seemed to have had a big quarrel with the Minister of Water Resources, and both parties were very emotional. The accompanying secretary asked me to leave temporarily and come back later. Who knows, disaster happened right after..."

Did the two of them even have a dispute?

Gu Ji and Fatima looked at each other and couldn't help but raise their eyebrows.
