He was reborn and became a firefighter again?

Chapter 510 The man who wants to die is here

Rumble.

One, two, hey.

chug chug.

Four days.

News came from the bottom of the mountain last night: A family member of a miner called the underground miner, but they only heard the sound of coughing. They hung up after a while and could not get through again.

This news, whether it is true or a lie made up by the family because they are afraid that the command will give up on the rescue, is exciting.

Therefore, under the continuous work of the three sounds of explosions, labor horns, and drilling rigs, the mountain of landslides in this ravine became increasingly empty.

Fang Huai felt like he was like Takeuchi Renshan in "My Captain, My Group". He dug out large and small holes in the mountain and then drilled them himself.

Now it seems that the job of digging out mountains is not easy.

The depth of the earth and rock accumulation reached more than 40 meters. The geological conditions were very complex and much more difficult than imagined.

Experts, who initially played no role, gradually took over.

Fang Huai's knowledge also increased dramatically: it turned out that he had to dig a deep trench, but there were so many things to pay attention to.

The top must be sloped outward to prevent water from entering and causing landslides; overexcavated earth must be dealt with in a timely manner to prevent collapse; the support plan must be constantly adjusted based on the site, and the control piles and elevations must be checked; construction cannot be performed on the same vertical surface at the same time.

It doesn't work if the soil is too soft.

A mountain that had only been formed for a few days could still lock in so much water, and some would seep out from the wall from time to time.

The construction plan was changed again and again, backfilling after excavation, and the direction changed. Every geological problem made Fang Huai anxious.

The target is the only source of water in that mine, the "water drain" not far from the water outlet.

Fortunately, the Mi-26 also arrived this morning.

Three excavators from the Hydropower Corps were hoisted into the site one after another. The elites from the Hydropower Corps, who had been digging out stones and soil with pickaxes in the past few days, finally got on the excavator and dug hard into the deep foundation pit. With a heavy hammer, the cleaning speed was as fast as a horse, and a 20-ton large drilling rig also came in, and the construction speed suddenly accelerated.

The most tiring ones are the technicians.

Every time you dig deeper, the technician who controls the geological radar will be hoisted down together with the radar car to detect it again. This is also the most anxious moment for everyone.

Geological radar can detect all media such as underground pipelines and cave materials by releasing radio pulses and receiving return signals.

However, the technology is not very mature. The detection depth depends on the face, ranging from a few meters to a maximum of more than 20 meters. In short, the closer you are, the clearer the detection.

Now, it’s time for the lottery draw again.

This time the technician was holding the detection monitor and frowning for a longer time than before.

Everyone was so nervous that they held their breath.

The technician suddenly raised his head and shook the monitor in his hand, with a surprised expression.

"Yes! Maybe there is!"

"La La La! Pull him up!"

Fang Huai said hello, and the safety harness on the technician's body suddenly tightened, and he lifted off the ground like a sling.

The technician was horrified.

"Hey, hey, slow down, slow down! Equipment, equipment!"

The equipment also came up suspended in the air.

As soon as the technician came up, everyone quickly gathered around him.

"What's going on? What's going on?"

Been digging for three days! I have been using instruments to continuously detect it since yesterday, and this afternoon, I heard a message for the first time! Can everyone not be excited?

"Wait a minute, don't panic!"

The technician operated the display screen in his hand, adjusted it for a long time, and handed it to Fang Huai.

"Look, does this structure look like the water channel in the drawing?"

Fang Huai frowned as he looked at the various K-lines on the instrument that looked like stock charts.

The technician quickly turned off the lines describing various media.

This time, the image is clear.

Like a long and narrow passage.

Fang Huai also nodded: "Yes, it's a bit like it! Where is it?"

The technician changed several interface diagrams and said hesitantly: "8 to 10 meters! Dig a few more meters and I'll take a look!"

Fang Huai suddenly felt excited and waved his hand:

"dig!"

Determine the location of the horizontal tunnel again. There is a location connected to the passage just below. As long as you see the concrete reinforcing the mine, you can break it and enter.

Two hours later, a clay figure came up from the gradually narrowing passage.

"Commander Fang! Water is seeping again! It's raining too! It's hard to handle! Why don't we follow the experts' advice and fill in clay first, seal the seepage opening, lay slopes to widen the passage, and make pedestrian stairs!"

Fang Huai narrowed his eyes and pointed to the watch on his wrist: "It's difficult to do it? It's been four days! It's already the fifth day! How long can they survive? No matter how difficult it is, we have to do it! After digging so deep, we have to dig again. We have to dig somewhere again! It’s too late! I hope we go down a few hours earlier and they can hold on!”

The surrounding soldiers swallowed.

Experts have said that water seepage channels must not be left alone and must be backfilled, as the chances of landslides are high.

In the current situation, there may be a collapse on the way down to continue excavation!

Moreover, the hole is now two meters square, which can accommodate two people. It has already gone down six to seven meters from the extension surface. It should have been widened and graded long ago. Otherwise, the excavator and large drilling rig will not be able to reach it, and it will have to be dug entirely manually. dig.

Fang Huai was a little excited just now. After thinking about it calmly, he knew that it was dangerous below.

So, I picked up the walkie-talkie and tuned it to the command channel.

Now, the soldiers of the Second Squadron who have undergone extensive search and rescue training are basically the commanders leading the peripheral search and rescue teams, and they are basically all in this channel.

"Guiyang Special Service Second Squadron."

Fang Huai pondered for a moment and continued: "Now we have a dangerous task. We have to go down to a passage about 7 meters deep in the well. We will continue to manually dig four or five meters down and enter the leveling tunnel. However, the passage may collapse from any position at any time. "Whether you come back or not depends on your luck. Who wants to go with me?"

This time, the intercom exploded.

"What a horse? Found it??"

"I go!"

".also go!"

"Team Fang, I am Wang Peng! I have just woken up and have the strength to go with you!"

".Pressed the intercom? Fang Huai, I'm Hao Chengbin! I'm going! I'm going!"

Walkie-talkies came and went, all calling for battle. Some refused to let others speak, holding down the talk button on the walkie-talkies and talking a lot.

Fang Huai waited for the call channel to open and immediately pressed the call button.

"If you want to go, come here and wait at the top of the slope."

At this time, several soldiers and commanders of the surrounding water and electricity troops panicked.

"Team Square, Professor Liu said that we can't let outside search and rescue people come in to dig, they don't know the dangers inside!"

"That's right! You are the deputy commander-in-chief of the front line, how can you go down? We didn't say not to go! So, you watch here, and two of us go down!"

Fang Huai waved his hand and walked up the winding pedestrian staircase, saying as he walked:

"It's okay. I'm aware of the danger. If you go and don't come back, I won't be able to explain it to your leader."
