"Hey, this person is really good, just do it, he doesn't rest when he gets out of the car, he has a lot of energy," Officer Tian saw that Yang Zijiang got off the car at the beginning, regardless of the fatigue of the long journey, he actually came down to work, which was really rare, and he couldn't help but admire it very much.

Seeing him skillfully moving again, climbing up and down to find leakage points, I was even more appreciative,

"Hey, I've found the right person this time, I'm so familiar with the situation in the cave!" He hurriedly told Yin,

"You can keep an eye on it, I'll go to the director to report, see what he needs, and provide it to him quickly. In addition, the top is too high, pay attention to safety, it is best to use your car below to pick him up to avoid danger, so high places must not fall, Yang Gong is now our No. 5 baby! ”

"Okay, don't worry, I'm here to keep an eye on it, and I promise that there will be no problems!" Yin readily agreed.

Secretary Tian waved his hand and left, he wanted to report Yang Zijiang's situation to the leaders, and he had to go back to the data room and file it. It will also take time to sort out these materials, and even if he is a civilian, he will not be able to interfere here.

Seeing that Secretary Tian was gone, Yin stood in the car and tilted his head to listen to Yang Zijiang's movements.

"Hey, why is there no sound, nothing will happen, right?" remembered Secretary Tian's advice,

"No, I've got to go check it out!" Yin was not at ease, so he also took a flashlight and went up.

"Ho!" It didn't matter if he went up, he found that the top of the cave and the bottom of the cave were completely two worlds, the bottom was resplendent and the top was primitive.

"How dare you love this?" He was very disappointed, not only was it damp and cold, but it was also covered with dust, why was it so rotten? It's not just dirty!

He spit out the dust in his mouth and shone it with a flashlight, only to see Yang Zijiang sitting there with a dirty face, pondering something?

"Hey, you can really stay in such a place. Let's go down after the survey, right? What does a person think here? ”

"Hey, how did you get in? It's too dangerous here, don't come in, just stay at the entrance of the cave, with you, not only is the light here poor, but there are snakes and scorpions or something, it's too dangerous to be bitten," Seeing Yin, Yang Zijiang hurriedly told him.

"Then you're so happy, huh? I don't wear protective clothing, I heard that the poisonous scorpions here are powerful, but it's a pity that I haven't seen them,"

"Hey, do you want to see it? I'll get you one? Yang Zijiang and Yin joked, "They are all lying under the stones, I just turned over the stones, good guys, more than a dozen, saw the light, swished and ran,"

"Mom, it's too embarrassing," Yin hadn't experienced it after all, and was a little timid in his heart, "I'll go down, you should hurry up!" ”

"Okay, I've basically found a place, look at me and go down!" Yang Zijiang agreed.

Looking at this place where work had been done, Yang Zijiang was very emotional. Because there is really not much change on the top of the cave. All of a sudden, he remembered the days and nights in this cave.

"At that time, how hard it was,"

Two shifts at 24 o'clock, it can be day and night, hard construction! Especially when working at height, it is seven or eight meters high. It's not just standing there. Instead, he worked with nearly 100 pounds of machinery. At the beginning, it was to use the drilling rig to hit the blast hole, not only to hold the machine with your hands, but also to use your shoulders or chest to push inward, with the strong vibration brought by the high-speed operation of the drilling rig, there is really no concentration is really not good, you have to be careful at any time, otherwise, you have to fall down if you are not careful.

At the beginning, I still tied a safety rope, but later I was too troublesome and secretly untied it. At that time, I relied on that tiger energy, and now I am panicked when I think about it.

Moreover, the roof of the cave above the head is uneven, and those are the granite with wolf teeth and jagged teeth, which can be bumped into if you are not careful. Think about it, "There are trembling planks under your feet, which will break at any moment, and your head is a cold blue-black rock", to be honest, people who are a little brave can't do it at all.

At that time, there were only a few hours of standing here, even if it was convenient, I couldn't come down, so in order to hurry up, I could only stand at a high altitude for convenience. To be honest, it was a really uncomfortable feeling, wearing bulky overalls, holding a heavy rig, and almost falling off a few times.

In addition to the harsh sound of the drilling rig in the cave, there is also a violent vibration of the drilling, no matter how thick the wooden board is, it is trembling and whirring, and the "creaking" sound is constant when walking, and the general Rao heart really can't bear it. These are those strong-willed and skilled old comrades to do it, and naturally Yang Zijiang is also in Zheng

After the cave is finished, it will be reinforced with concrete. Although the intensity of the work is not so high, the work is more tiring. There are those who are in charge of mixers, and there are those who are specialized in transporting cement, sand, and gravel. These materials are poured into the concrete mixer according to the proportion. When the machine is mixed, it becomes sticky concrete, and they do the pouring task.

The machinery in the cave could not be used, and the pouring of concrete had to be done manually. But in any case, the cave is also several meters high, and it has to be poured up in several layers, with two people on each floor, throwing concrete up in shifts. To be honest, that's really a lot of effort, and each spade is less than 30 pounds.

Think about it, except for the 30 minutes of each break, how tiring it must be to lift up and down and do monotonous movements there?

So, as soon as the rest time came, the young warriors immediately collapsed beside the pile of rubble, lay down and fell asleep.

"At that time, it was really hard!" Yang Zijiang sighed.

He has basically completed the investigation, and he basically knows the phenomenon of leakage on the roof of the cave.

"If the guess is correct, this should be a capillary leakage phenomenon," he said to Yin patiently after he came down. Recommended reading: sm. s..

After the arch of the cave roof is completed, a lot of stones are pressed layer by layer, so that the vault and the mountain can form a whole.

"It's good, but in this way, there is a disadvantage, as long as the rock leaks, it will cause water to accumulate on the roof of the cave, and once it cannot be discharged, it will corrode a place for a long time. Over time, this place will cause water seepage,"

"Is there any good way to plug the leak?"

"Yes, there is, but some materials are needed,"

"This is easy to do, let's go outside to purchase leak-proof spirits!" When he was working on the pool, Yin saw that the workers had used it, so he immediately proposed, and he was a little excited to think that he could go outside.

"No, you can't go out and buy it!" Yang Zijiang poured a basin of cold water on him.

"Why?" Seeing that his suggestion was rejected, Yin was a little discouraged.

"The waterproof materials sold outside are all big road goods, and they are almost waterproof for baths and swimming pools, but our situation is the leakage of the roof of the cave, especially the concrete vault, once the capillary phenomenon is formed, it is difficult to put an end to it. The first thing to do is to find the cracks or holes that are causing the water seepage, as well as the silt spots. So, it's best for us to mix it ourselves! ”

"Okay, what materials do you want? I'll get it for you outside, I'm good at this! Yin was excited again...... read3;
