At the beginning of the fire scene, I was rescuing people, and I was broadcast live as a firefighter

The Ping'an Hotel was instantly stir-fried.

The man who has been working in the kitchen keeps apologizing to everyone.

The diners were also very understanding of the man's feelings, and left the restaurant one by one.

Li Xiao rushed back to the fire squadron non-stop, and the fire squadron was already in a mess at this time.

Due to his late return, the entire squadron was left with one fire engine on standby.

He hurriedly changed his equipment, got on the fire truck and set off in the direction of the Changqing Tunnel.

Inside the fire truck.

Everyone's expressions were very serious, because such a large-scale disaster accident is very rare.

What's more, as they knew, all 6 fire squadrons in the DG city were dispatched.

Furthermore, when I ask for support from the fire squadron of the town below.

They clearly understood how dangerous this catastrophe was.

Zhang Wenxin helped Mo Xingwan and sorted out the equipment on his body, and reminded everyone:

"This time, it is expected that at least 50 fire brigades will be dispatched from the towns below to come up to support.

"With the addition of these six squadrons in our urban area, the number has broken 400 people.

"This mission will be very dangerous, Mo Wanxing and Liu Qiang, you two newcomers, you must be careful and careful. "

Li Xiao, don't act impulsively for me again, you must report to your superiors before doing anything

!" "This, understand!"

in the live broadcast room.

"Oh my God, what are so many firefighters going out to do together?"

"Didn't you hear the news? The Changqing Tunnel collapsed.

"Lie to me, I just passed by there this morning to go to work.

"Now that the news is all over the place, how can it be fake?"

"It's true, there's traffic control over there, and there's no way to get into the nearby roads." "

·····

The fire truck galloped all the way, and thanks to the help of traffic control and traffic police comrades, several people soon came to the vicinity of the Changqing Tunnel.

At this time, more than a dozen fire trucks were parked next to the emergency lane.

Some firefighters who arrived early have already begun to clean up the debris and car wreckage on the perimeter.

Seeing the tunnel that had completely collapsed, Li Xiao was stunned.

The original tunnel entrance was now covered with rubble and traces of various explosions.

The extensive collapse of the tunnel even affected the structure of the mountain.

A large amount of earth has slid down the hillside, and the original retaining wall has lost its proper function.

Large chunks of retaining walls, washed down by the pouring mountain, obscured a small part of the tunnel entrance.

At this time, a large number of firefighters were carrying away the reddish-brown dirt.

Several researchers dressed in white clothes and wearing white engineering hats were rapidly using computers to analyze the situation in the Changqing Tunnel at this time.

The squadron leaders of the various squadrons who had already arrived were whispering behind several researchers.

"This evergreen tunnel is too old.

"The 30-year-old tunnel, even if the maintenance work is relatively good, there are many problems. "

It's troublesome, stuck in the rush hour after work.

"According to the usual traffic here, the number of people trapped inside is not a small number. "

It's another tough battle!"

"It's not easy to deal with our current situation." "

In the whispered discussion of several squadron leaders, several computers made a dripping sound, apparently indicating that the preliminary analysis had been completed.

Several squadron leaders immediately stopped talking, and they approached the researcher, wanting to see the results of the analysis first.

The researchers quickly concluded:

"Based on sonar detections, as well as what we expect through system modeling. The

researcher hesitated for a few seconds, gritted his teeth, and continued

, "It can be very bad, we've simulated it more than 1,000 times with computers.

"The best result, the most stable central area that has ever been reinforced, still retains a safe area of about 100 meters.

"At worst, the 1,120-meter tunnel fell except for the north entrance, which was more than 100 meters away.

"With 85 percent of the simulation results left, there is no complete collapse in the tunnel, no more than 100 meters. Hearing

the results of the study, the hearts of all squadron leaders chuckled.

They knew it was a big deal.

Just listen to the researcher continue:

"The tunnel on the south side 10 10 yuan a truck rear-ended and overturned, and the subsequent explosion directly damaged the main structure of the tunnel. "

The huge explosion caused structural resonance, causing some of the already aging structures to fall apart in an instant.

He pointed to the computer diagram:

"You see, the buildings of normal tunnels are all sectional. "

Segmentation is usually done every 100 or 150 meters to avoid resonance in the main structure.

"However, the construction of the Changqing Tunnel is more than 35 years old, and at that time it was the use of integrated irrigation technology.

"Although the designers have innovatively made mechanical support and protection at some nodes of the tunnel 35 years ago, the effect is minimal.

As he spoke, he drew an oval in the middle of the tunnel, encompassing one of the tunnels.

"Only the middle section of the tunnel was strengthened three years ago. "

It is reinforced with aluminum alloy and RMA engineering plastics, which is very good in terms of strength and extension.

"So we speculate that this section of the reinforced section will not have a high risk of collapse.

"If other people can enter this section of the tunnel in time, then the safety factor is very high. "

As for the rest of the place.....

the researcher pursed his lips and didn't finish his sentence, but none of the people present were stupid.

Everyone understands what the researcher is trying to say.

Those who can enter the middle of the tunnel will survive safely.

The subtext is that those who can't get in are probably going to be very difficult to survive.

Thinking of this, everyone's hands and feet were a little cold.

The length of an ordinary car is 5 meters, due to the accident during the rush hour when the traffic is most intensive.

Therefore, it is very normal for there to be traffic jams in the Changqing Tunnel.

The length of a car, plus the distance between the two cars, adds up to a total of 10 meters.

The total length of the Changqing Tunnel is 1,120 meters, and the north entrance has a distance of about 110 meters without collapse.

In other words, the total length of the collapse of the Changqing Tunnel is about 1,000 meters.

Even in the best-case scenario, the central 150 meters of the tunnel did not collapse.

Then the length of the collapse is also 850 meters.

A simple conversion shows that there are at least 85 cars in one lane.

The Evergreen Tunnel is a three-lane tunnel, which means that at least more than 250 vehicles are trapped inside.

Even with only one passenger and one driver per vehicle, the number of people trapped was more than 500.

After this data, everyone felt a little dizzy.

At this time, a black business vehicle quickly stopped next to the emergency passage from far and near.

Two middle-aged men and an older man got out of the van.

The old man looked a little old, but he was in good spirits.

The three of them walked quickly to the temporary command post, and after learning about the specific situation, the old man's face also became ugly.

"Your fire brigade will immediately start a rescue operation, and I will apply to the military region for emergency resources. "
