Chapter 269: Bottomless
It is really unbelievable that an excavator sank in the deep pool of the deserted mountain village, how did the excavator drive in, and how did it sink into the water?
Everyone approached the shore to watch, the excavator had been sunk in the water for some time, and many parts of the fuselage had been mottled and rusted. The glass of the cockpit of the pen www.biquge.info Pavilion was intact, and it could be seen that it was empty.
"It's weird!"
Ziyang took off his shoes and socks and wanted to wade into the water to get closer to watch, but was pulled by Su Rui.
"Be careful, it's deep here!"
Because the water is very clear, the actual water depth is much deeper than it seems. The excavator looked not far from the water, but was actually at a depth of about ten meters.
"I found the excavator when I first got here, and I didn't look closely. After Professor Zhang took over here, he once seconded a Z-8 heavy helicopter, which I guess is the equipment that Professor Zhang and his team later transported. Jin Guoqiang stared at the excavator in the water and said in a deep voice.
"I see that the water surface here has expanded a lot more than when we came last year, could it be that Professor Zhang and his people dug it?" Zi Yang turned his head and asked.
Jin Guoqiang shook his head: "No, I didn't see the excavated earthwork around, and the change in the water surface was due to the rising water level." There's a lot of weirdness about this excavator parked here, you see there! ”
Following the direction of Jin Guoqiang's finger, you can see that a winch is installed in the front of the excavator, and there is a thumb-thick steel cable along the winch, which stretches straight to the center of the pool. Because the light in the depths of the water is very dark, the black steel cable blends in with the surrounding water, and it is blocked by the huge body of the excavator, so it is difficult to spot this steel cable without looking closely.
Su Rui looked at it carefully, frowned, and said, "The excavator seems to have been dragged down." ”
Jin Guoqiang also nodded: "Judging from 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 distance, and the water level rose, so the excavator was drowned in deep water." ”
Ziyang looked carefully, and sure enough, he found that there were two shallow grooves about ten meters long on the slope behind the excavator, which should have been dragged out by the tracks.
"It's strange, what's in the water that can drag a ten-ton excavator that far?"
It can be seen that the original position of the excavator is relatively flat, and it should not have "accidentally" slipped into it.
Jin Guoqiang raised his head and squinted his eyes to look around, except for the sound of the wind blowing the reeds, there was no other sound. The east and west rivers of Tanshui are also as calm as a mirror, and the flow of water is almost invisible.
"Don't you think it's a little strange that there aren't a lot of fish in such a big pool?" Jin Guoqiang said softly: "Judging from the situation at the scene, Professor Zhang and the others should have temporarily terminated the investigation operation, and the excavator was discarded in the water like this, indicating that they were also in a hurry to retreat." ”
Ziyang scratched his head and said, "It's really a little strange, is there something strange in the water?" ”
Jin Guoqiang stared at Ziyang with two eyes: "Do you still continue to insist on detecting the waterhole?" ”
Zi Yang swallowed his saliva and looked at Su Rui hesitantly, "It's all here......"
Su Rui nodded and said, "Let's go to a shallow place to explore it tentatively, and if the situation is abnormal, we will stop diving." I'll go down with Ziyang. Captain Jin, you can help us monitor it above, is it okay? ”
Jin Guoqiang sighed and said helplessly, "Okay, since you insist, I have no opinion." ”
Su Rui nodded, dragged his equipment to the reeds to change clothes, and after a while, Su Rui, who was wearing a wetsuit and carrying an oxygen tank, walked out of the reeds.
Ziyang also changed into a wetsuit with the help of Jin Guoqiang.
Su Rui handed a walkie-talkie to Jin Guoqiang, "There is a built-in walk-in in our wetsuit, which can realize three-way communication, and after we go down, we will be notified in time if there is any problem on it." Jin Guoqiang nodded, "Check the equipment again to see if there are any omissions." ”
In order to take care of Ziyang, a half-baked diver, Su Rui prepared a covered mask this time, which can cover all faces. With it, divers can breathe with their mouths and noses as if they were on land, avoiding the problem of uncoordinated mouth-nose breathing for beginners like Aprisa.
Zi Yang and Su Rui checked each other's diving equipment again, and after confirming that there was no problem, Su Rui seriously told Zi Yang: "Wait a minute, if you need to dive deeply, you must abide by several principles: the first is the principle of two people walking together, if there are no special circumstances, the two of us must be together; Second, stay in touch at all times, and if you're alone, stay calm and wait for me. ”
Zi Yang nodded, and Su Rui continued: "There is another important point, you can't stay in deep water for too long, if you dive deeper than 40 meters, you must decompress, don't float too quickly, stay at 10 meters and 5 meters respectively, and try to empty the air in your lungs when you float, otherwise your blood will boil like beer and foam." ”
Zi Yang swallowed his saliva, looked at Su Rui and Jin Guoqiang with a little panicked, and already had a little retreat in his heart. But they have already come to this point, and it is too late to regret it, and now they have to bite the bullet.
Su Rui saw that Zi Yang was a little nervous, and comforted him and said, "Just relax and listen to my instructions." If the intercom fails, we communicate with gestures: OK, which means that I am in good condition now; If you want to alert your teammates in a certain direction, use your index finger to indicate it; Float up, make a fist with your right hand and thumb up; Dive down with your right hand into a fist and thumb down. ”
Ziyang nodded repeatedly.
"If it's okay, let's get ready to dive."
Su Rui stood in the water, bowed twice and wiped it on Ziyang's face to help him get used to the temperature of the water.
Both of them wear full-body covered wetsuits, which can maintain 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, but the most important thing is the psychological factor.
"Hey, we've started climbing, where are you?"
The sound came from Ziyang's backpack on the shore, and it was Lao Wang greeting them.
Zi Yang walked over and took out the walkie-talkie, "We're also at the foot of the mountain-don't talk if it's okay, it's a waste of electricity!" Zi Yang put the walkie-talkie back in his bag and looked at Su Rui and Jin Guoqiang, "Let's go!" ”
The two put on their masks and walked slowly into the pool, and after a while they were submerged in the water.
Xiao Hei stretched his neck to look at the water, and then looked at Jin Guoqiang, the expression on his face was confused and worried.
Jin Guoqiang patted Xiao Hei on the shoulder and motioned for him to relax, and the two sat on the shore, staring at the two black figures in the water swimming towards the excavator.
Zi Yang and Su Rui swam to the side of the excavator, looked at the hollow cab, the steel cable mounted on the front winch had turned to the bottom, Su Rui pulled the straight steel cable that collapsed with his hand, and found that the steel cable did not move at all, and it seemed that something heavy had fallen below.
The other end of the steel cable goes straight into the middle of the pool, where the water quality has turned blue-black because the sun does not shine, forming a black disc at the bottom of the pool, and I don't know how deep it is below.
Su Rui tied the yellow guide rope to the excavator and said in the intercom, "We're going to dive deep down the tightrope." ”
"Okay, stay safe." Jin Guoqiang on the shore said.
The two swam along the steel cable to the center of the pool, as the depth increased, Ziyang obviously felt that the water temperature dropped rapidly, Su Rui turned on the light on the wetsuit, which could illuminate a few meters in front of him, and the center of the pool was still bottomless.
"Following me, we descended slowly. If there is a problem, say it promptly. Su Rui said softly.
"Okay, OK, no problem." Zi Yang gestured, trying to calm down his voice to hide his nervousness.
When the steel cable reached the center of the pool, it began to descend straight, and the two slowly dived down along the steel cable, Ziyang stared at the water pressure gauge on the diving suit, which showed 15 meters, 18 meters, and 21 meters......
Following the light on the wetsuit, you can see the steep cave walls all around, and the depths of the waterhole are actually straight cylindrical shapes.
When I descended to more than 30 meters, it was still dark and I couldn't see the bottom, and when I looked up, there was only a white shiny disc left on the surface of the water.
When the counter showed 40 meters, Su Rui stopped: "This depth is already the limit for you, if it is deeper, you need to do phased decompression, the operation is more complicated, you stay here, I will take a look at the situation." ”
"Otherwise, let's go back now, I look like it's still very deep below, and I can't see the bottom for a while." Ziyang was a little flustered.
"Su Rui, safety first, don't be reluctant." Jin Guoqiang also said in the intercom.
"It's okay, I'm professionally trained, so it's okay to have a little depth. Ziyang, wait here. After Su Rui finished speaking, he went downstream without waiting for the two to answer, and after a while, the light on the wetsuit disappeared in the deep water.
"Su Rui, what's next?" Zi Yang couldn't see Su Rui's figure, and couldn't help but feel nervous again.
"Relax, breathe slowly." Jin Guoqiang heard the strangeness in Ziyang's voice and said slowly on the walkie-talkie.
In this kind of underwater space, which resembles a closed waterspace, it is easy for a person to feel suffocated, and Ziyang's breathing has begun to become rapid.
"I'm okay" Su Rui's voice finally came from the intercom again, "The water depth here has reached 68 meters, strange, I still haven't seen the bottom - hey......"
There seemed to be a murmur in Su Rui's intercom, and it suddenly broke off after a few sounds.
"Su Rui, Su Rui!" Ziyang shouted involuntarily.
"What's going on?" Jin Guoqiang also said on the shore.
"Su Rui's call is broken, there may be an unexpected situation, I, I'm going down to find her!" Ziyang almost shouted.
"No, you're not trained to dive! Further down there will be danger! Jin Guoqiang ordered from the shore.
"But...... So what about Su Rui? Zi Yang looked at the black waterhole under his feet and said anxiously.
"Wait a little longer, maybe it's just a malfunction of the intercom." Jin Guoqiang tried his best to comfort Ziyang with a calm voice.
Zi Yang looked at the diving watch in his hand anxiously, 1 minute, 2 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.
Ziyang finally couldn't wait any longer, and said into the intercom: "I'm going down!" ”
As soon as I released my hand from the guide rope and was about to dive, I saw a flash of light suddenly appear below. The light below the waterhole gradually became clearer, and Ziyang saw Su Rui slowly float up from underwater.
When he arrived in front of Ziyang, Su Rui clenched his right hand into a fist, his thumb pointed upward, and made an upward gesture.
The two of them slowly ascended, and after stopping at different depths to decompress, they finally slowly surfaced.
The two took off their masks, and Jin Guoqiang and Xiao Hei came over to help the two of them ashore.
"Su Rui, you, are you okay? Why did the communication suddenly break just now? Zi Yang looked at Su Rui's face and said.
Su Rui tilted his head and wrung out the water from his wet hair, "I'm fine, the intercom is malfunctioning." When I dived about 70 meters deep, I seemed to see the ground, but I was running out of gas cylinders, so I had to come back first for safety. ”
Jin Guoqiang nodded: "Well, the further down you go, the greater the consumption - by the way, before the call was disconnected, you seemed to have a question, did you find anything?" ”
Su Rui nodded, and said with a solemn face: "I saw the end of the tightrope. ”
