An excavator was sunk in a deep water pool in a deserted mountain village. This is really incredible. How did the excavator get in and how did it sink into the water
Everyone approached and watched along the shore. The excavator had been in the water for a while, and many places on the fuselage had been mottled and rusted. The glass in the cockpit is intact, and it can be seen that there is no one inside.
"It's weird!"
Zi Yang took off his shoes and socks and wanted to wade closer to watch, but Su Rui grabbed him.
"Be careful, the water is deep here!"
Because the water is very clear, the actual water depth is much deeper than it looks. This excavator does not seem to be far from the surface of the water, but it is actually ten meters deep underwater.
"I discovered this excavator when I first arrived here, and I didn't investigate it carefully. After Professor Zhang took over here, he once seconded a Z-8 heavy helicopter. I guess this is the equipment that Professor Zhang and the others later transported. "Jin Guoqiang said in a deep voice, staring at the excavator in the water.
"I think the surface of the water here is much larger than when we came last year. Could it be that Professor Zhang and the others dug it?" Zi Yang turned his head and asked.
Jin Guoqiang shook his head: "It's not like, there is no excavated earth around. The water level changes because of the rising water level. There are a lot of strange things about this excavator parked here, look there!"
Following the direction of Jin Guoqiang's fingers, you can see that a winch is installed on the front of the excavator. Along the winch there is a steel cable with the thickness of a thumb, which stretches straight to the center of Tanshui. Because the light in the depths of the water is very dark, this black steel cable is integrated with the surrounding water quality, and it is blocked by the huge body of the excavator, it is difficult to find this steel cable without looking carefully.
Su Rui looked carefully and frowned and said: "The excavator seems to have been dragged down."
Jin Guoqiang also nodded: "From the perspective of the soil level below, there is no water in the place where the excavator was originally located. It should have been dragged down for a certain distance, and the water level has risen, so the excavator was submerged in deep water."
Zi Yang took a closer look and found that there were two shallow grooves about ten meters long on the slope behind the excavator, which should be the slip marks dragged by the crawler.
"It's weird, is there anything in the water that can drag a ten-ton excavator so far?"
It can be seen that the original location of the excavator is relatively flat, and it should not have slipped in accidentally.
Jin Guoqiang raised his head and squinted his eyes to look around. There was no other sound except the rustling sound of the wind blowing on the reeds. The east and west rivers of the lake are also as calm as a mirror, and the flow of water is almost invisible.
“Don’t you think it’s strange that there are not many fishes in such a big pool?” Jin Guoqiang said softly, “From the situation of the scene, Professor Zhang and the others should have temporarily terminated the investigation and the excavator was just discarded Being in the water means that they were also in a hurry to retreat."
Zi Yang scratched his head and said, "It's a bit strange indeed, is there something strange in the water?"
Jin Guoqiang stared at Zi Yang: "Do you still continue to detect the waterhole?"
Zi Yang swallowed and looked at Su Rui hesitantly, "I'm here..."
Su Rui nodded and said, "Let’s go to shallow water for tentative exploration. If the situation is abnormal, we will stop diving. I will go down with Zi Yang. Captain Jin, you can monitor it for us, can you?"
Jin Guoqiang sighed and said helplessly, "Well, since you insist, I have no objection."
Su Rui nodded and dragged his equipment to change clothes among the reeds. After a while, Su Rui, wearing a wetsuit and carrying an oxygen cylinder, walked out of the reeds.
Zi Yang also changed into his wetsuit with the help of Jin Guoqiang.
Su Rui handed over a walkie-talkie to Jin Guoqiang, "Our wetsuit has a built-in intercom, which can realize three-way communication. After we go down, let us know if there is any problem on it." Jin Guoqiang nodded, "Check the equipment again, see Are there any omissions."
In order to take care of Zi Yang, a half-sail diver, Su Rui prepared a covering mask this time, which can cover all the human face. Wearing it, divers can breathe with their mouth and nose just like on land, avoiding the incoordination of nose and mouth breathing for beginners like Zi Yang.
Zi Yang and Su Rui checked each other's diving equipment again. After reconfirming that there was no problem, Su Rui told Zi Yang earnestly: "If you need to dive deep, you must abide by a few principles: The first is two. The principle of walking with others, if there is no special situation, we must be together; second, keep in touch at any time, if you are alone, keep calm and wait for me where you are."
Zi Yang nodded, and Su Rui continued: "There is another important point. You can't stay in deep water for too long. If the diving depth exceeds 40 meters, you must decompress. Don't float too quickly. Stay at a distance of 5 meters and try to empty the air in your lungs when you float up, otherwise your blood will boil and foam like beer."
Zi Yang swallowed, looked at Su Rui and Jin Guoqiang with a flustered expression, and already had the thought of retreating in his heart. But I have already reached this point, and it is too late to regret it. Now I have to bite the bullet.
Su Rui saw that Zi Yang was a little nervous, and comforted him: "Relax a little and just listen to my instructions. If the phone fails, we use gestures to communicate: OK, it means I’m in good condition; if you want to remind your teammates to pay attention to something Use your index finger to indicate the direction; float up, make a fist with your right hand, thumb up; dive down, make a fist with your right hand, thumb down."
Zi Yang nodded repeatedly.
"If it's okay, let's get ready to dive."
Su Rui stood in the water and put two cups of water on Zi Yang's face to help him adjust to the temperature of the water.
Both of them are wearing full-body wetsuits, which can maintain their body temperature in deep water without worrying about the rapid drop in temperature in deep water. Diving is a test of technique and physical fitness. However, the most important thing is the psychological factor.
"Hey, we have started climbing, where are you?"
The voice came from Zi Yang's backpack on the shore, and it was Lao Wang greeting them.
Zi Yang walked over and took out the walkie-talkie, "We're at the foot of the mountain too-don't talk anymore, it's a waste of electricity!" Ziyang put the walkie-talkie back in his bag, looked at Su Rui and Jin Guoqiang, "Let's go. !"
The two of them put on face masks and walked slowly into the pool, before being submerged in the water after a while.
Xiao Hei stretched his neck and looked at the water, then at Jin Guoqiang, the expression on his face was confused and worried.
Jin Guoqiang patted Xiao Hei on the shoulder and motioned him to relax. The two sat on the shore, staring at two dark figures in the water and swimming towards the excavator.
Zi Yang and Su Rui swam to the side of the excavator and saw that the cab was hollow. The steel cable mounted on the front winch had been turned to the bottom. Su Rui used his hand to pull the straight steel cable that collapsed and found that the steel cable did not move. It seems that something heavy has fallen below.
The other end of the steel cable plunged straight into the center of the pool, where the water quality had turned blue-black because of the lack of sunlight, forming a black disc at the bottom of the pool, and it was unknown how deep it was below.
Su Rui tied the yellow guide rope to the excavator and said in the intercom: "We are going to dive deep down the steel rope."
"Okay, pay attention to safety," said Jin Guoqiang on the shore.
The two followed the steel cable to swim towards the center of the pool. As the depth increased, Zi Yang obviously felt that the water temperature dropped rapidly. Su Rui turned on the light on the diving suit to illuminate a few meters ahead. The center of the pool was still deep. Not bottomed out.
"Follow me, we slowly descend. If you have any questions, please tell me in time." Su Rui said softly.
"Okay, OK, no problem." Zi Yang made a gesture, trying to calm down the voice to conceal his nervousness.
When the cable reached the center of the pool, it began to descend straight. The two slowly dived along the cable. Zi Yang watched the water pressure gauge on the diving suit, which showed 15 meters, 18 meters, 21 meters...
Following the lights on the diving suit, you can see the steep walls of the cave all around, and the depth of the pool is actually a straight cylinder.
When it descended to more than 30 meters, the bottom was still dark and invisible. Looking up, there was only a white shiny disk on the water.
When the counter showed 40 meters, Su Rui stopped: "This depth is already the limit for you. If it is deeper, you will need to perform periodic decompression. The operation is more complicated. You stay here and I will look down. It depends on the situation."
"Or, let's go back now, I think it looks like it is still deep below, and I can't see it for a while." Zi Yang was a little panicked.
"Su Rui, safety first, don't force it." Jin Guoqiang also said in the intercom.
"It's okay, I have received professional training, and this depth is okay. Zi Yang, wait here." After Su Rui finished speaking, he went downstream before the two of them could answer. After a while, the light on the diving suit was in deep water. Disappeared.
"Su Rui, what's next?" Zi Yang couldn't see Su Rui's figure, and couldn't help but feel nervous again.
"Relax and breathe slowly." Jin Guoqiang heard the strange voice in Zi Yang's voice and said slowly on the walkie-talkie.
In this kind of closed underwater space, a person is prone to suffocation, and Zi Yang's breathing has begun to rush.
"I'm okay." Su Rui's voice finally came from the intercom. "The water depth here has reached 68 meters. Strangely, I still haven't seen the bottom-Huh..."
There seemed to be a noise in Su Rui's intercom, which suddenly cut off after a few sizzling noises.
"Su Rui, Su Rui!" Zi Yang shouted involuntarily.
"What's the matter?" Jin Guoqiang also said on the shore.
"Su Rui's call has been interrupted. An unexpected situation may have happened. I, I have to go down to find her!" Zi Yang almost shouted.
"No, you have not received professional training, you can't dive deep! There will be danger further down!" Jin Guoqiang commanded from the shore.
"But... what about Su Rui?" Zi Yang said anxiously, looking at the black puddle under his feet.
"Wait a second, maybe it's just a malfunction of the intercom." Jin Guoqiang tried to comfort Zi Yang with a gentle voice.
Zi Yang looked anxiously at the diving watch in his hand. One minute or two minutes passed, and there was still no movement below. In Zi Yang's heart these two minutes seemed to be as long as several hours.
Zi Yang finally couldn't wait any longer, and said to the intercom: "I'm going down!"
Just loosening the guide rope, when I was about to dive, I saw a ray of light suddenly appeared below. The light below the pool gradually became clear, and Zi Yang saw Su Rui slowly floating from the water.
When he reached Zi Yang, Su Rui made a fist with his right hand, thumb up, and made an upward gesture.
The two slowly ascended, and after staying at different depths and decompressing them, they finally slowly surfaced.
The two took off their masks, and Jin Guoqiang and Xiao Hei came over to help them ashore.
"Su Rui, you, are you okay? Why did the communication suddenly break off just now?" Zi Yang said while looking at Su Rui's face.
Su Rui tilted her head and wrung out the water on her wet hair. "I'm fine, the intercom is malfunctioning. When I dived to about 70 meters just now, I seemed to see the ground, but my gas cylinder was about to run out. Safety can only come back first."
Jin Guoqiang nodded: "Well, the more you go down, the more consumption it will consume — by the way, before the call was disconnected, you seemed to have a question, did you find anything?"
Su Rui nodded, and said solemnly: "I saw the end of the cable."
