Yun Yang said: "You see it." He pointed at a spot in the photo with his hand, and then said: "Only this circle can be preserved. However, this is the most even force. The situation, that is to say, as long as there is a deviation, then the four floors will collapse except for the load-bearing wall. It is impossible for them to collapse at the same time, but faster here and slower on that side. In this case, the load-bearing wall will collapse The wall will also produce a linked collapse with the effect of this collapse. Of course, the load-bearing wall on the first and second floors... may still stand. After all, the upper part is offset and may break, but the first and second floors The stress on the layer will then stop and lighten. Thus it will be preserved."
Du Shengli nodded beside him at this time. He and Jiang Bin were both from the engineering battalion in the army. Don't underestimate the engineers. When people think of engineers, they may clear mines or blow up bridges. In fact, in addition to these, engineers need to master many skills and even some basic construction principles. Therefore, engineers are definitely a technical branch.
Moreover, these two people are good at blasting and bombing. Why? Maybe you can provide some raw materials for the bomb, and ordinary soldiers can detonate it. But if you want to be proficient, you need to understand other things, such as a house. What are the key points? Ordinary demolitionists may not understand this and can only blow up the house by increasing the amount of explosives.
But Jiang Bin and Du Shengli knew exactly where to place the bomb at a glance, and they could destroy the house with very little explosives. If you don’t know some architectural knowledge, you will never be able to do this.
When they heard Yun Yang's explanation, the two of them immediately understood what it meant. Du Shengli said: "In other words, in fact, we do not need to destroy the central load-bearing wall around the stairs. As long as these eight load-bearing columns are blown up, then the outer wall of the building alone will definitely be damaged. If the building cannot support it, the entire building will collapse completely.”
"Yes." Yun Yang nodded and said, "That's the situation."
Fan Keqin actually understood it, but in a rigorous attitude, he asked again, "What is the probability? There won't be any surprises, right?"
"Oops. An accident..." Yun Yang carefully considered his words in order to achieve a more precise description, and said: "How should I put it... Sir Fan, it's like I accidentally cut a cut on my hand. But, After you go to the hospital and get stitches, the doctor still won't give you a 100% guarantee that nothing will be the same for you. However, nearly a thousand people with such wounds have undergone the same treatment. In fact, accidents are only rare cases. There are 999 cases where the injury will be completely recovered."
After Yun Yang finished speaking, he clicked the photo again with his hand and said: "What I said is the same as the case of blowing up eight load-bearing columns. I can't say that there is no possibility of accidents. But the probability is very, very very low."
Fan Keqin smiled and nodded, saying: "That's good. This is more convenient."
It is indeed convenient. The load-bearing wall is really difficult to explode. If it is of a certain length, you can't just place a bomb at one point. Instead, press and release a bomb every once in a while. Otherwise, the effect of landslide will not be achieved at all.
Next, Yun Yang told everyone the specifications of the load-bearing columns and load-bearing walls, and marked them on the photos with a pen. Jiang Bin and Du Shengli asked Yun Yang in detail about technical issues.
Qian Jinxun then pressed the buzzer and said, "Xinran, please come in."
Kong Xinran came in after a while, and Qian Jinxun said: "Take Mr. Yun to the General Affairs Department and ask them to arrange a dormitory with a better environment. Mr. Yun will live here for a while."
Kong Xinran nodded and said, "Yes." Then he looked at Yun Yang and said, "Mr. Yun, please follow me." The two of them left immediately.
Fan Keqin said: "I suggest that we make several load-bearing pillars according to specifications, proportions, materials, etc., and then Jiang Bin and Du Shengli, you two, do some practical research as soon as possible to see what kind of explosive is more convenient and the best It would be nice to have a sticky bomb, the kind that sticks to the wall."
Qian Jinxun said: "Well, I'll find the place." Then he looked at Jiang Bin and Du Shengli and said: "You two have been here recently. My intelligence department also has all kinds of blasting materials. If you need anything, just ask .”
After that, Qian Jinxun looked at Zhao Hongliang again and said, "Old Zhao, go find a secret place in the suburbs, and then ask the brothers to build the load-bearing pillars according to what Yun Yang said, and be quick. You can bring Yun Yang with you when you do it. When it's done, take Jiang Bin and Du Shengli with you immediately and start studying how to explode it."
"Yes." Zhao Hongliang stood up and answered, "I'll go to my humble position now." Then he said hello to Fan Keqin, turned around and walked out of the office door.
Jiang Bin looked at Du Shengli and said: "Actually, the best way to blast this kind of load-bearing column is to drill holes, and then put explosives in and detonate. Only in this way can the kinetic energy of the explosion achieve the best effect. But drilling holes will take a long time. Impossible to consider.”
"Yes." Du Shengli said: "If you don't mind it, you can also use sticky bombs like the one mentioned in the chapter. For example, how about using butter? This thing needs to be made in a factory workshop, or a place like a car repair shop. It's relatively easy to get there. When the time comes, put it in a bucket during the operation, and then, before releasing it, you just need to dip the bomb in the bucket, take it out and stick it to the wall."
"Yeah. This is a good method." Jiang Bin said: "Put the bag on your back, carry it with your left hand, take out the bomb and dip it in... I think it will work. It won't take much effort."
"It's just..." Du Shengli said: "Brother Jiang, I have a concern. You see, as you said, we can't drill holes. How can we fully utilize the kinetic energy of the bomb? If the bomb is attached There’s so much wasted energy on the surface of the wall.”
Jiang Bin frowned and thought for a while, then said, "What if we explode on both sides of the load-bearing column at the same time."
"At the same time..." Du Shengli thought for a while, nodded and said, "I think it will work. The front and back sides are exploded at the same time, which is equivalent to the two bombs giving each other kinetic energy. The load-bearing column is in the middle, so the power of the explosion will be doubled. Time fuse...how about using one?”
"Yes." Jiang Bin smiled and said: "Yes, use one. This way there will be no time error and it can be guaranteed to detonate at the same time..."
