At night in Zambia, the temperature is as low as ten degrees, which is in sharp contrast to the high temperatures of more than thirty degrees during the day.

Lying in the temporary tent, Zhao Guoyang felt a chill on his body.

There is no way, because after just arrived in Zambia the day before yesterday, his speech shocked the audience. In the past two days, Zhao Guoyang was pestered by Minister Toulouse every day and could not go back to the embassy to rest.

After Zhao Guoyang waved his hand and determined the optimal rescue plan, the rescue operation at the mine disaster site had officially started.

In the past two days, the on-site staff successfully opened four small-diameter life-saving holes, and found some trapped people underground through holes 2 and 3.

The operation had achieved such remarkable results at the beginning, and it was no wonder that Minister Toulouse was very fond of Zhao Guoyang.

However, after the small-diameter life-saving hole was opened, new problems arose.

In the past two days, because the geological structure of the mine here is very complex, 300 meters from the surface to the top plate of the underground tunnel are topsoil layers, limestone layers, sandstone layers and gypsum layers.

Except for the topsoil layer, the other three layers are mixed with limestone and have two aquifers, which has caused drill bits to be stuck many times in the drilling rescue, which seriously affects the progress of the operation.

It is easy to open the small-diameter life-saving hole at present, but if you want to do it in the same way, open a large-diameter hole that is enough to put into a life-saving cage and rescue the trapped people below one by one, the difficulty will be greatly increased.

At present, the two drilling rigs that have arrived at the rescue site in advance, the two drilling rigs of the American "Caterpillar" company and the German "Liebherr" company, the kbr360 and the lbh200, have been proved that they cannot complete the task of opening a large-diameter life-saving hole.

Among the support teams of most African countries, including Zambia, Zaire and Nigeria, there is no product comparable to these two drilling rigs.

In this way, the rescue work fell into trouble.

Just during the day today, the Minister of Toulouse, who was sweating profusely, personally called the "African National Mutual Aid and Rescue Organization" and asked them to provide urgent support.

But unfortunately, drilling rigs that meet the requirements are hard to find on the African continent. Even the "African National Mutual Aid Rescue Organization" is nothing more than a "African National Mutual Aid Rescue Organization".

As for the powerful rescue teams, they are also a little helpless.

Needless to mention the two teams in the United States and German, "kbr360" and "lbh200" are already the best performance among the drilling rigs in the two countries.

But even so, they have been proven that there is no way to play a role at the mine disaster site.

As for the two products of Komatsu Productions in the island country, although they are particularly unique in some aspects, in terms of comprehensive performance, they are still far from the two drilling rigs.

Therefore, when the "Joint Command" discussed this issue during the day, Ichiro Matsushita did not mention this.

Several powerful countries were helpless about this, which made Toulouse anxious.

After several rescue team leaders from America, England and France begged for grandpa and sued their grandma, Toulouse could only ask for permission to Zhao Guoyang again.

Thinking of Toulouse's sad look when he begged for him in the morning, Zhao Guoyang had no choice but to agree to think of a solution for him.

Seeing that Zhao Guoyang agreed, Toulouse suddenly became a little alive, and even helped him arrange the tent next to the joint command center so that he could contact the outside world through the command center's phone number at any time.

At this time, Zhao Guoyang and Huaxia's rescue team lived separately, which is for this reason.

After recalling what happened during the day, Zhao Guoyang silently thought about what to do next.

The current situation is already quite clear.

My own rescue plan is definitely not a problem, and it has been recognized by rescue teams such as America and Germany.

Now the small-diameter life-saving hole has been opened and contacted with the trapped people underground. The next step is definitely to find a way to save people.

According to the analysis of relevant geological experts, there is a large amount of groundwater below this mine disaster site.

The height of his position is dozens of meters higher than that of the trapped survivors.

In this case, if a large drilling rig cannot directly penetrate the limestone layer, sandstone layer and gypsum layer, or vibrates too much, it will easily cause damage to the sandstone layer, causing loosening of the surrounding groundwater, thereby causing serious consequences.

Therefore, the biggest problem before Zhao Guoyang is to find a suitable drilling rig.

This drilling rig not only needs strong power, but also has sufficient stability to ensure the smooth and smooth implementation of the construction process.

It is really difficult to find a drill rig with such high requirements in a short period of time.

Even the technicians of the "Caterpillar" company, one of the world's top engineering machinery companies, will have to be redesigned at least two months before they can come up with products that meet the requirements.

It takes at least three months to design, plus production and transportation.

Even if there is a life-saving hole now, it is impossible for the underground personnel to survive for so long.

After all, the air content below is definitely insufficient. When the carbon monoxide concentration is too high, it is likely to cause large-scale casualties.

According to life experts' speculation, the air underground can last only a little more than a month according to the demand of seventy or eighty people, which is still under the condition that the life-saving hole is kept ventilated.

The difficulty is now obvious, so let’s see how to solve it.

Of course, Zhao Guoyang dared to agree to Toulouse, but he had some confidence.

His confidence lies in the brand new "sms company".

In fact, what many people don’t know is that “sms Engineering Machinery Group”, as early as last year, had already acquired 60% of the shares of “Daewoo Heavy Industry” and became the actual controller of “Daewoo Heavy Industry”.

The chairman Zhao Guoyang, the chairman, owns up to 55% of the shares, and is the largest shareholder of "Dayu Heavy Industry".

Therefore, many of the products of "Daewoo Heavy Industry" are actually products of "SMS Company" in terms of affiliation.

As the parent company, the technical interaction between "SMS Company" and "Daewoo Heavy Industry" has not stopped.

Just like the crane transported from Zaire before, it was jointly designed and researched by the two companies based on a heavy crane from Daewoo Heavy Industry.

In the past year, the two companies have designed as many as five or six new products, and each has a very good sales volume.

But for drilling rigs, in the past year, no new products have been brought out, whether it is "SMS Company" or "Daewoo Heavy Industry".

If you want to come up with a suitable product in such a short time, you can only rely on the old products of "Daewoo Group" to improve it.

I originally planned to think about it carefully and call Jin Xiuzhu. But Zhao Guoyang thought about it and asked some things clearly first.

So after tossing and turning for a while, he still felt like getting up and going to the joint command center next door to make the call.

Zhao Guoyang had just gotten up and went out when he met the dusty Toulouse.

Minister Toulouse was stunned when he noticed the coat Zhao Guoyang was wearing.

"Uh, Mr. Zhao, I'm thinking about whether I want to wake you up. I didn't expect you to wake up by yourself. It's so great!"

After a little stunned, Toulouse hurriedly held Zhao Guoyang's hand, afraid that he would run away.

Zhao Guoyang smiled and said, "Mr. Toulouse, don't worry, we Chinese people have the most important promise and will never be a 'deserter'! I will definitely do what I promised you!"

"Ah, that's great!" Toulouse nodded repeatedly.

After talking to this person for a few words, Zhao Guoyang explained his purpose.

"That's right, Mr. Toulouse, I just thought about it carefully and still have to get the big drilling rig done first, so I decided to call my business partner and ask her for help!"

Toulouse didn't expect Zhao Guoyang to take the initiative to mention this matter, and he was overjoyed at the time.

He pulled Zhao Guoyang's arm and shook his mind, "That's great, it's great, Mr. Zhao! You want to make a long-distance call, right? Then come into the house and call me quickly. I'll help you stay outside!"

Seeing that the minister wanted to help him guard the gate himself, Zhao Guoyang was a little ridiculous.

He shook his head helplessly and said, "Mr. Toulouse, you can stay in the house. My phone call with my friend is nothing shameful!"

"No, no, I didn't mean that!" Toulouse touched his smooth forehead awkwardly, but did not move anymore.

Zhao Guoyang smiled at him gently, and then walked to the place where the telephone was placed.

After picking up the phone, Zhao Guoyang quickly dialed Jin Xiuzhu's number.

"I am Kim Soo-joo, who are you?"

When Zhao Guoyang heard Miss Jin's lazy voice coming from inside, he looked a little gentler.

"Miss Xiuzhu, I went to bed so early. It's not eight o'clock yet?"

"Ah, Guoyang?" Jin Xiuzhu was obviously a little happy when she heard Zhao Guoyang's voice.

"Yeah, it's me!" Zhao Guoyang smiled and replied.

"Guoyang, why do you have time to call me today? Oh, I understand. You bribed any subordinates around me. Do you know that I will go to your China next month?"

Zhao Guoyang knew nothing about Jin Xiuzhu's plan. He smiled slightly and denied: "No, Xiuzhu. I called you, there is something important to tell you, I want to ask you for help!"

When Zhao Guoyang said solemnly, Jin Xiuzhu was stunned.
Chapter completed!
