my mountain and river space

Chapter 141 The Swamp Anecdote
[Goodbye Ideal], in order to thank you for your reward, I will add a new chapter now, book friend group: [-], welcome new and old friends to leave their footprints.

According to the plan, the piling will be completed today, but these piles are not good, so we must find a way to solve them.They even want to pour it with concrete!Xu Ling thought about it in his heart, and felt that it was wrong, because Longzhu Mountain was not far to the south. If it was the underground river, there would be a big problem.

"Instructor Shen, do you think it's okay to get out of here? Look, you can avoid it by moving five meters in each direction." Xu Ling pointed to the four sunken piles on the drawing, and moved outward in four directions.

"But our steel frame has already been customized. If the foundation is changed, the steel frame above will definitely be useless." Instructor Shen said to Xu Ling.

"The others will not be affected, just these three rows." Uncle Li pointed to Xu Ling.

Xu Ling also scratched his head. He was not a professional in this matter, so he said to them, "Let me ask Mr. Yuan." Unexpectedly, Uncle Li interrupted, "No need to ask, Lao Yuan said that there is either an underground river or something like that down there. It's a cliff-like depression. Once it's penetrated, there's nothing you can do unless you rivet it down one by one." Uncle Li shook his head at Xu Ling, indicating that he had called earlier.

"What should we do now?" Xu Ling asked Instructor Shen.

"Strip foundation! Make use of other complete pile positions to make a strip foundation." Instructor Shen obviously has an idea.

"This method is good, simple and cost-effective." Xu Ling also admired, and looked at Instructor Shen with admiration in his heart.While Xu Ling and the others were talking, suddenly there was a rumbling sound from the four swallowed concrete piles, and the whole place seemed to be affected and vibrated!The workers and soldiers who were working immediately ran back. A worker operating the pile driver may have been too flustered and fell when he fell to the ground. His fellow workers did not dare to go back to rescue him.The ground trembled continuously, and the round piles on the ground also rolled.The two soldiers looked back and saw someone fell, so they went back to help him without hesitation.Xu Ling and the others also loudly told them to come back quickly and stay away from the swamp.

The piling position and the adjacent swamp vibrated more and more violently, and even the watery mud in the swamp splashed like boiling. The pile driver suddenly fell to the ground, and with a bang, two piles were broken. out of shape.There are many birds in the swamp itself, all of them are looking for food or chasing and fighting each other. When the vibration started, they immediately soared into the sky, but they did not fly away, circling and singing at low altitude.

Suddenly, the soil disappeared at the place where the four piles disappeared, and the soil next to it also sank in that direction. Xu Ling and the others were surprised. Fortunately, all the personnel had returned. Unreasonable!
"Ah!", the pile driver worker who had just been helped back by the soldiers turned pale with fright, and would have knelt down on the ground if his legs hadn't been supported.Not grateful but frightened, trembling with fright.When he came back to his senses, he kept thanking the two soldiers and said that he would invite them to dinner tonight, otherwise today's old fate would be an explanation.

Seeing this, other people applauded enthusiastically, and Xu Ling also smiled and extended his thumb. The people's soldiers didn't shout for nothing, and it really depends on them at the critical moment! "Instructor Shen, I can't help but say that today's dinner at the fish restaurant and barbecue restaurant is mine!" Xu Ling said to the soldiers.

"Okay!" With a loud bang, the soldiers were all beaming with joy. They had heard that the food inside was a must. Many people from other provinces would come here to order a table, which shows how delicious it is.

"You bastards, leave my words here. If you can't finish the work on time, I will settle the score with you! Also, be more careful in the future. If you see anyone in the village who needs help or who affects safety, give me a helping hand!", Instructor Shen He also had a happy face, and he didn't dare to eat alone. It would have a bad impact if word spread about it, but Xu Ling treated everyone, so that's another story.Listening to others talk about the delicious food inside every day makes me feel excited.

Standing in the distance, you can occasionally see the soil rolling down in the sunken place, but you can't hear the sound of falling.When almost everything calmed down, Xu Ling took the lead and walked forward slowly. This time, he didn't know whether it was a ground subsidence or something until he approached.

When they reached the edge of the subsidence, everyone looked at the bottomless black hole ahead in shock!Just in the middle of the four piles, there is a black bottomless round hole at the bottom of a pit similar to the bottom of a pot. Now there is water vapor rising from it, and the soil next to it is falling down. But there is no sound!

"God, how did this come about? What's underneath? Why is there such a big space." Uncle Li also found it inconceivable.

"I have seen tiankengs in the southwestern mountainous area, and I have also gone down from the tiankengs into collapsed potholes. But this collapsed hole made me feel very uncomfortable." Instructor Shen said with a frown.

Xu Ling moved forward to approach the collapsed hole, and a cold breath came over him. Along with the water vapor, goose bumps appeared on his body.Looking at the bottomless black pothole again, a terrifying aura pervades.Xu Ling mentally probed down, but unfortunately, within a detection distance of 20 meters, there was only soil on the cave wall, and nothing was found.It's just that the lower the temperature is, the lower the temperature is, and the water vapor is also abnormally cold.

Everyone looked at each other. This strange hole appeared. What should we do?Xu Ling looked at instructor Shen. They were mainly responsible for this matter. It was up to them.

Instructor Shen thought for a while and said to everyone: "Take a break first, I'll make a call." After speaking, he took out his mobile phone and dialed Professor Sima and the others.

After a while, Professor Sima and Professor Zhang all came, and they were quite surprised when they saw this collapsed hole.Professor Jetson came later, and even brought a set of wired detection equipment: a miniature camera and receiving equipment, and a battery.All the lights are ready, a few channel steels are built on the upper part of the pit, and then a thick plank is laid, and the person stands on it and controls the electric switch with his hand to slowly lower the camera.

The first dozen meters are fairly bright, so most of it is relatively clear. The cave walls are full of pits, and loose soil is still falling down. In some places, swamp mud is pouring out, but the sound of falling is not audible, even if The same goes for camera machines with sound collectors.

Going down to about 20 meters, only the lighting range of the machine can be seen, and the rest are all black. The soil turns from black to black and yellow, which should be the humus part.However, there was not much mud gushing out, and some fell on the camera, blocking part of the line of sight.

After descending more than ten meters straight, suddenly something appeared in the line of sight, it was a stone, it should be a collapsed stone, uneven, with teeth and sharp corners, not thick.Xu Ling speculated that it might have been broken after the piling was shaken just now, and the cave could not bear the weight of the top, so the cave collapsed.But what happened to the shock before the collapse?It stands to reason that there will not be such a big movement.

The camera did not go down quickly, but slowed down while spinning. Professor Jetson wanted to know some information about the structure of this swamp, hoping to find something from here.

Gradually, everyone found that the camera became less and less clear. After a closer look, it turned out that a thin layer of ice had formed on the mirror in front of the lens, blurring the picture. The operator looked at Professor Jetson and asked what to do.

Jetson gestured helplessly to come up.Xu Ling went over to catch it and found that the entire small machine was bitingly cold, with a layer of white frost on the outside. There was no way around it, as there was no insulating lens!

Uncle Li thought for a while, and suggested a solution with Jetson, "When we are cold in winter, we usually turn on a high incandescent lamp to heat up quickly. But if we need to pull electricity, the battery power is definitely not enough at this point." Jetson agreed Today, the cave must be probed.The incandescent lamp is very dangerous without protection. Uncle Li used a large wire with a similar hardness as a support to let the incandescent lamp shine in front of the camera.This will work.

Sure enough, there was no problem in descending to the position just now. After such a short period of time, the dripping mud was also reduced, which made the operator much more relaxed.But this cable is only 50 meters long, I don't know if it is enough.

When we descended to about 40 meters, the black-yellow soil began to change again, turning black.This is too strange, and Xu Ling is also puzzled. It stands to reason that the further down it should be, it should turn yellowish or turn to red clay or gravel.
