Super Technology Extractor

In Qin Shiqi's impression, Liang Yueke's usual performance is still very good, capable but also very interesting, knowing what he can and cannot do.

The warning range of the core experimental building cannot allow employees below level 5 to enter. Liang Yueke's level is sufficient, but she never crossed the yellow warning line drawn on the ground, even if it was a step.

Therefore, when the broadcasting system said that Liang Yueke was waiting around the door, Qin Shiqi felt that the company should have a problem.

Looking at the other elevator leading upstairs, Qin Shiqi reluctantly chose to walk towards the door.

"Oh!" The heavy security door lowered.

"General Qin, something went wrong and the experimental building collapsed! The city just called and the company's experimental building at the foot of the mountain collapsed. No, there was a large pit on the ground with the experimental building and the workers inside It all fell into it. "

Before Qin Shiqi asked, Liang Yueke hurriedly said something briefly.

"You wait!" Qin Shiqi murmured in his heart, then immediately turned and ran towards the experimental building, high heels rattled continuously.

After a while, Fang Hao's figure appeared at the door, frowning. "Assistant Liang got into the car and said as he walked."

The commercial vehicle configured by the company drove over quickly. After the three of them got on, they drove directly to the Shanjiao factory in the western suburbs.

Liang Yueke didn't know much. She re-narrated to the Fang Hao what the city government told, and when they did, a vigilance belt was already around the scene.

Dozens of police cars stopped at the intersection, several fire engines flashed with warning lights, and the roar of the motor rang continuously. On the hook at the rear of the car, a cable was stretched and the other end went directly to Inside the pit.

Fang Hao's car just stopped, and two business cars also quickly drove next to the car. An emergency brake stopped directly at 5 meters beside the pit.

A group of people on the bus quickly came down. They brought professional tools. Two of them, Fang Hao, had met in college before and were a professor of geology at Jiangnan University. The other is a professor at the School of Civil Engineering.

The scene was a bit messy, with people shouting, the mechanical operation of the engine, and the sound of various equipment.

The three Fang Hao were called in by a police officer, and a built warehouse was used as a temporary command room.

After entering, Mayor Zheng Chengbu was next to the two professors who had just arrived, and there were a few students who should be professors. A group of people were watching the video screen transferred from the drone.

"General Fang, you are here." It was Hu Xingguo who spoke.

"Sorry, late, deputy mayor, are there any casualties inside?"

"Fortunately, we just ended the call. Two workers broke their legs and the others were minor injuries. No one is currently dead."

Although Fang Hao wondered how the experimental building would all collapse into the pit, how did that pit form?

But human life is greater than heaven.

Listening to Hu Xingguo's words, Fang Hao lowered his heart slightly.

As long as the people inside are fine, the experimental building will be rebuilt.

Hu Xingguo continued to say what he knew: "It happened at 9 am. According to what we have now, 33 workers were in the laboratory building at that time.

It happened very suddenly, the people at the scene only felt the ground shake, and then the whole experimental building fell down. "

But neither he nor the construction team who worked on the site before. No one can tell exactly what happened at the time. Everything was too sudden and too fast. The workers in the experimental building simply did not have enough time to run. come out.

When introducing the situation, Fang Hao had gathered in the crowd and squeezed in.

"China's carbonate strata are distributed in about 1/3 of the country's land area, and it has significant solubility. In areas with strong rainfall and groundwater activity, it is prone to ground subsidence geological disasters."

The professor pointed at the screen and said, "Mayor Zheng, look here, here you can see the intrusive quartz diorite porphyry, and here the erosion is obvious. It should be a karst collapse."

Karst collapse, its unique karst hydrogeological conditions is an important reason for the formation of karst ground collapse.

The flat shapes of karst collapse include circular, elliptical, elongated, and irregular shapes, which are mainly related to the opening shape of underlying karst caves and the uniformity of the distribution of properties of overlying rocks and soils on the surface.

The size of the collapse is characterized by the size of the individual collapse pits, which mainly depends on the degree of karst development.

According to statistics, the diameter of soil subsidence pits generally does not exceed 30m, of which the majority are less than 5m, accounting for 63% -71%, 5-10m account for 10% -20%, and some large ones can reach 60-80m. The visible depth of collapse pits is mostly less than 5m, which can account for 84% -97% of the total.

However, there are exceptions. There has been a giant karst collapse pit with a depth of more than 100 meters.

The drone continued to fly downwards, and the water flowing outward between several rock layers in the picture, Professor Zhou's face became increasingly ugly. "Trouble, the karst collapse caused the underground river to change course."

really!

As the drone descends, more and more water penetrates outward from the gaps in the rocks, and the gaps are getting larger and larger. Several gaps have become water columns, and the building covered with cracks and faults on the surface. Sink it out.

The drone carefully avoided the water column and approached the building.

The camera was pointed between the faults, and the dense steel bars were exposed to the air, bending at a speed that was visible to the naked eye.

After making a circle, the drone could not find the entrance to the experimental building, nor could it pass through the building that was tilted down there to check the condition under the building.

"You must save people immediately! Judging from the pictures taken, this experimental building is not yet complete. Now we don't know what is blocking the bottom, but the experimental building is falling further." Professor Zhou quickly gave a professional Judge.

It was very clear that everyone present understood.

No one can judge how deep the karst pit is now. However, the state of the building now shows that it must not be able to withstand the second impact.

There is a more serious problem. As more groundwater is poured into the building, the weight of the building will increase, leading to unpredictable changes.

Once the balance between the experimental building and the potholes is changed, the workers trapped inside are basically hopeless.

"Tutor! I remember!

I've seen detailed exploration data here in the school's archives! "

A student from Professor Zhou suddenly shouted aloud, and then hurriedly asked the students in the college to send surveying and drawing paper and geological surveying data.

After Professor Zhou saw the data sent, he no longer knew what to say.

"Mayor Zheng, we are ready."

Professor Zhou's face was sore and painful. At that glance, he knew what this sentence meant.

Give up?

…………

Outside the command post, several pile-driving machines were operating at overload, and the ground piles were driven into the ground. Several firefighters were carrying heavy steel ropes around their arms to cover the exposed ground piles.

Then the steel rope was thrown into the pit. They were going to use the steel rope to fix the experimental building below the ground first. In case of the second collapse, the steel rope can bear a little weight, and try to ensure the safety of the personnel inside.

At the intersection, another car stopped quickly, and it was Zhou Zhuo who got off.

Because the construction of the industrial park was affirmed by Fang Hao, the construction here is also responsible for them.

The first time he heard the news, he rushed over, got out of the car, a gust of wind passed, and UU read a book www. Uukanshu.com blows him with a shiver all over.

Now it's winter, today the highest temperature is only 2 °, but Zhou Zhuo is sweaty and even his back is soaked.

"Comrade, I belong to the Heavenly Group. The project here is done by us." Zhou Zhuo and the policeman in charge of guarding the cordon explained it to him before being put in.

Seeing the group of people standing, Zhou Zhuo's heart was completely cold.

The city leaders came in person, Mr. Fang was also on the side, and there were several professors. He knew both professors and had not asked them for help before.

Even they are here, Zhou Zhuo knows that this matter has made a big deal today.

Running hurriedly, when he came to Fang Hao, he said bitterly, "Fang ... I ..."

"This is not to say at this time, wait for someone to come up and talk." Fang Hao set off.

Fang Hao listened to the discussion at the command post just now.

The main reason for the underground collapse of the experimental building is due to geological problems. The ground conditions in this area are very special, and it is completely supported by a raised point of a rock formation.

If there is no one to move, due to the geological situation of Anlin City, the possibility of collapse is not too great, but it is bad or bad. Here you need to build a factory. There are many supporting experimental buildings, warehouses, and workshops.

How could Fang Hao not think that the situation in the underground would be so complicated, let alone that he had stayed in such a place for nearly a year before.

According to Professor Zhou, this area used to be the geological disaster prevention area of ​​Anlin.

So when the city was built, it was excluded from planning.

And even if it doesn't collapse now, there will be a little shock in the future, this place will collapse!

Fang Hao was shocked. He was just standing outside the gate and chatting with the ghost inside!
