"It's because of the complex geological structure and the lack of technical conditions, so I will go thousands of miles to the big leaders for help," Hearing that the tall and tall political commissars were embarrassed, Director Dong knew that this project must be difficult to shoot in real time!

"I don't know it's so complicated? At the beginning, I heard Liu Li on the phone, you are digging caves in the desert, the longest is several kilometers long, and the construction team is led by the political commissar Fang. Thinking that you must have been very experienced in fighting caves for a long time, so I volunteered to ask for help, so I know that there will be so many things in the project? Hearing them say that the structure of the mountain is so complex, he was also worried.

"Hehe, you also know that you are worried?" Seeing Director Dong frowning, Fang Bojing smiled, "There are so many of us, not to make it difficult for you, but to let you know the complexity of the geological structure here, so that you can have a mental preparation, this is not braised pork, swallow it in one bite, this is a hard bone, and it is a particularly difficult bone to gnaw, understand, old man?" ”

"What do I mean, you don't want to do it?" Director Dong asked,

"Haha, my Doctor Dong, do you think that we are going to go home when we come here in such a big way, and it is difficult to make a sound? Then you look down on us too much? What do we do? An order from above, a vigorous action below! There are certainly difficulties, and they are difficult enough, but don't worry, they won't scare us away! Honestly, if it weren't for the fact that this bone was hard to gnaw, why did you go all the way to call us over? ”

"How do you know it's so complicated?"

"Complexity is complexity, and whether you can do it or not, these are two different things," Yangtze Zijiang said in a serious tone, "The difficulty is that it is placed there, and it cannot be moved." But there is no doubt that since we have arrived, there is no way back. Don't be a tunnel, there is a mountain of swords and a sea of fire in front of us, we have to break in, otherwise I'm sorry folks, and I'm even more sorry for you? ”

"Yang Zi's right, I like such fighters. No matter how complex its geological structure is, in order to allow the villagers to drink a sip of clean water, and for future generations not to get this mountain disease again, there is no condition, and we have to create conditions, which is Wang Tieren! Fang Bojing was half joking and half serious.

"You are the iron men of modern times!" Director Dong expressed his appreciation, "I am down-to-earth as soon as you two are like this, just now I thought you were going to pick a son and quit?" Alas, if you can't do it equipped with modern tools, then the folks even more want to do it, look at the primitive tools in their hands, don't know yet? ”

"No matter how complex the geological structure is, there is a way, isn't it Yangzi?" Political Commissar Fang was full of confidence, "Don't look at him!" ”

"Then you, what are the tricks to deal with such a complex geological structure, by the way, also learn and learn, and when you open the road next time, I will understand,"

"Haha, you're really ambitious, what? Don't want to be a doctor? Fang Bojing joked with him,

"I'm half-medical, half-working, in case the political commissar leaves, I can also help the command!" Director Dong is witty, but from the bottom of his heart, he also wants to understand.

"The specific construction steps are as follows: first open the working surface, then hit the blast hole, blast, clean up the gravel, and gradually push inward. The first few steps are fine, and with the equipment in our hands, the construction progress should be fast at the beginning, and there will be no problems. The body surface of our mountain is on the bright side, and the key problem is inside! Yang Zijiang said in detail,

"I have told you just now, our construction principle is to disturb, diligent support, and use scientific and reasonable excavation methods. Especially when the working face is blasted, it is necessary to grasp the specific situation of geology, scientifically and reasonably arrange the operation, so that the section of the excavation is very close to the drawing design, and the construction data must be measured uninterruptedly at any time, and it is strictly forbidden to over-dig and under-excavate! ”

Yang Zijiang is very professional. When Director Dong heard it, he asked rhetorically, "What do you mean by over-digging and under-digging?" ”

That is to say, for the main body of the tunnel, it is necessary to constantly measure and master the construction data, and it is not possible to dig big, and it is not possible to dig! The construction design must be strictly implemented. Moreover, the support works will have to follow! Yang Zijiang told him in detail.

"I see you've brought in a lot of tubular facilities, are they for support? What exactly does it do? Director Dong saw that the equipment piled up on the side of the road was all pipes one by one, which was very fresh.

"Hehe, that's not a pipe, it's a jack specially used for support. Its main purpose is to prevent stones from falling or debris from collapsing. There is also a cave wall support! ”

"It's no fun for so many people to work and be hit by falling stones! Safety is important! ”

"Safety is naturally important, but that's only one of the roles of support. The main purpose of doing support is to be afraid of accidents. Why can't you overdig or underdig? Do you want to do a good job of support at any time? It is the fear that the stone will fall, causing a large area of the cave wall to collapse, especially from the pressure above the cave wall. If you can't do a good job of support at any time, or over-digging or under-digging, it will inevitably cause landslides or water gushing. So, those modern support equipment you just saw make a big difference! Yang Zijiang explained carefully and deliberately emphasized the key points.

"Understood, the support equipment you brought is awesome, 100% confident!" Director Dong expressed his satisfaction, "Since the safety is guaranteed, let's start working hard!" What else are you worried about? ”

"Hey, Director Dong, you can't say this," Hearing this, Fang Bojing immediately interjected, "Steady and steady, step by step, diligent support, disturbance, this is the principle, no one can forget it?" "Fastest update s.. sm..

"You're right," Yang Zijiang expressed his support, "we must stick to our principles." Director Dong, don't you see that in the face of nature, any advanced tools are pale and powerless! We've suffered big losses, do you remember that, commissar? ”

"Why don't you remember, that time was that the gravel fell more and more, and then the landslide area became larger and larger, and the big stones were piled up all over the roadway, because it was too late to run out, and everyone was blocked inside, Wang Xingcai was not sacrificed that time? But there were no casualties that were caused! ”

"Yes, if you don't do a good job of support, blindly advancing, it is easy to cause large-scale collapse or water gushing, and at that time, what kind of advanced equipment is useless!" When it comes to these, the two of them are still a little afraid!

"Yang Zi, let's talk to Director Dong so much first, right? Remember, the principle must not be forgotten! Let's prepare today, and start work tomorrow! ”

Fang Bojing looked at Director Dong's expression and knew that he couldn't understand it just by talking about it. Therefore, it is recommended that Yangzijiang stop explaining, and he will understand when he does it.

But what Fang Bojing didn't expect was that even if such a careful arrangement was made, an accident finally happened because of the intricacies of the geological structure...... read3;
