"Always bring an oxygen cylinder, survival is king, everything else is the result of survival. This is a classic line from the film "The Abyss", which is based on the real experience of the screenwriter Andrew Waite, which tells the story of Issa Ala, the "mother of caves" in Papua New Guinea, who has a rich diving experience.
For diving enthusiasts, Issa Allah, a huge cave that has not yet been fully explored, is exuding a unique charm that attracts them to check outIn Guangxi, China, there is also such a place for diving enthusiasts to check in - "Peach Blossom Jellyfish Skylight".
"Peach Blossom Jellyfish Skylight" is located in Du'an County Disu Underground River Geopark, when its discovery caused the bombardment of diving enthusiasts, from the surface, this "skylight" sparkling is a beautiful landscape, but under this beautiful landscape there is a huge danger, the famous "1115 diving accident" happened here.
On November 15, 2020, five people from the Nanning Diving Club in Guangxi Province came to the "Peach Blossom Jellyfish Skylight" to see the "beautiful face", but this time 4 people were launched, 3 people returned safely, and a female diver from Chongqing was killed at 140 meters.
How did this Chongqing female diver get killed?And how was the body recovered from 140 meters?How deep is this "peach blossom jellyfish skylight"?Why is there such a danger in such a beautiful landscape?
The real name of "Peach Blossom Jellyfish Skylight" is Badin Pond, which is given a romantic name "Peach Blossom Jellyfish Skylight" because of the world's rare ancient creature peach blossom jellyfish.
Badingtan is located in Dongmiao Village, Dongmiao Township, Du'an County, Yao Autonomous Region, Guangxi Province, which is a national geological park with the theme of karst underground river, karst landform relics and paleontological relicsThe total area of the park is 175 square kilometers.
The terrain of Guangxi Zhuang Autonomous Region is complex, mainly karst landform, and soluble rocks have formed many sinkholes, karst caves, deep pools, etc. under the action of groundwater and surface water.
According to the description of the local villagers, the villagers used to like to wash clothes near the Badin Pond, but once a buffalo fell into the Badin Pond, the buffalo is a creature that is good at water, it stands to reason that the buffalo can climb out of the water on its ownBut the buffalo sank to the bottom of the pool and disappeared.
One pass ten, ten pass hundred, people are more and more curious about Badin Pond, and the "mystery" of Badin Pond also makes the expert team's heart itch.
After the expert team came to the location of Badin Pond, they learned some legends about Badin Pond from the local villagers, and then the experts conducted a deeper study of Badin Pond.
In the process of diving, the expert team found some small fish and some shrimp with bright bodies in the Badin Pond, and the expert team did not stay too long and continued to dive.
As the depth of the dive increased, the expert team found that the visibility under the water gradually decreased, and could only rely on the faint light to grope forward.
In this dive, the experts did not dive to the bottom of the pool due to the lack of oxygen in the oxygen cylinder, and could only rely on the only data to analyze the Badin Pool.
Experts said that because of the long-term rainwater erosion caused by the expansion of the sinkhole, coupled with the largest underground river system of the underground river system of the Su underground river cut to form the shape of an inverted funnel, under the influence of karst landforms, there are curved branches and multiple openings under the water, and the whole Badin Lake is bottomless.
The bottomless unknown and complex karst terrain make the mysterious Badin Pond a popular place for many diving enthusiasts.
In mid-June 2011, when the Guangxi special police were conducting diving training in Badingtan, they found the peach blossom jellyfish, a national first-class protected animal, in the skylight near Jiazhutun.
The peach blossom jellyfish is known as the "giant panda in the water", is a kind of shape like a peach blossom on the verge of extinction of the ancient and rare coelenterate, this ancient organism has very high requirements for the environment and water quality, and the peach blossom jellyfish found in the Badin Lake also verifies that the water quality of the Badin Pond is clear and thorough, and the unknown that you can't see the bottom of the pond at a glance also explains the danger of the Badin Pond to some extent.
The Guangxi special police also found that the water quality at the location of the underground river under the waterhole is the clearest, so it is also called "the first skylight of the peach blossom jellyfish".In addition, under the "medium" of the underground dark river, the entire range of several hundred meters is the world of "peach blossom jellyfish skylight".
"Cave exploration is full of unknowns and dangers, but it also stimulates the cells of diving enthusiasts.
The "bottomless" of Badin Pond has made it a veil of mystery, the water quality is clear, the discovery of peach blossom jellyfish makes Badin Pond the first choice for diving enthusiasts, but the occurrence of diving accidents also increases with the increase of diving enthusiasts, the famous "115 diving accident" occurred in the "second window of peach blossom jellyfish".
On November 15, 2020, five diving enthusiasts from the diving club in Nanning, Guangxi Province, brought their diving equipment to the beautiful landscape "Peach Blossom Jellyfish Skylight", which has always been the most desirable diving spot for their diving enthusiastsToday, they also want to see what the most beautiful scenery in this world looks like.
At around 12 o'clock in the afternoon, five divers decided that four of them would dive, and the remaining one would take care of the equipment on the shore, and the "mystery" of Badin Pool made them excited, thinking that they would soon be able to enter the water, and all five of them were extremely excited.
At the same time, they also kept in mind that this mysterious myth could only be explored at a height of more than 100 meters, so they set a position at 34 meters of Badin Pond and turned back to shore.
Ten minutes later, the two divers turned back to the shore, and the moment they surfaced, the two looked at each other in shock, only the teammates who took care of the diving equipment on the shore, and the remaining two divers did not surface.
After two diving enthusiasts went ashore to adjust their diving equipment, and then there was a dive into the water to search and rescue two other diving enthusiasts, at about 13 o'clock in the afternoon, two diving enthusiasts surfaced with another companion, four people looked at each other, realizing that another diving enthusiast was killed, at 14 o'clock, the four people dialed the ** of the Guangxi Police Department.
Four divers said that the other diver who did not surface was a Chongqing girl, who was an extreme diving enthusiast who followed her teammates to Bading Lake to see the beauty and experience the excitement of Bading Lake.
On the same day, the famous diving master Li Xudong (Gao sir) and the Du'an Blue Flag rescue team participated in the search and rescue of the female diver in Chongqing.
The Doan Blue Flag rescue team quickly put on their diving suits and dived to the air chamber in the underwater cave of Badin Pond, the first search and rescue site, which is a space where air exists in the underwater cave if the diver encounters danger underwaterIf you hide in the air chamber, you may survive, so the air chamber of the underwater cave is called a "shelter".
However, the Blue Flag rescue team searched in the gas chamber of the underwater cave for a long time and did not find the Chongqing girl, in other words, the Chongqing girl was more likely to be killed.
It was November in winter, and the visibility under the water was very low, and there were unknown holes and ravines at depths of 110 to 160 meters, which made it dangerous for even experienced diversFor this reason, the Du'an Blue Flag rescue team could only look for the Chongqing girl at a position of more than 90 meters above Badingtan.
On the 16th, after a night of search and rescue, the Du'an Blue Flag rescue team did not find the Chongqing girl who was killed, and it was obvious that the Chongqing girl who loved diving had met with an accident.
At this moment, the task of rescuing the Chongqing girl also turned into salvaging the body of a female diver in Chongqing, and the old cat with a depth of 202 meters in the Chinese cave also participated in the salvage mission that dayThe old cat is a well-known diver, and his joining gives hope to the rescue team again.
From November 16th to November 19th, the Blue Flag rescue team continued the rescue mission the night before, and the rescue team members took turns to go into the water 90 meters to find the figure of the Chongqing girl who was killed, but the rescue team searched all the areas above 90 meters, and did not find the Chongqing girl who was killed, so they could only hope for the underwater robot.
On the night of November 19, the underwater robot entered Badingtan to look for the Chongqing girl who was killed, and sure enough, the underwater robot dived to 143 meters of Badingtan and found the body of the Chongqing girl who was killed.
Next, the task of the Blue Flag rescue team is to successfully salvage the body of the Chongqing girl who was killed, but the water depth is 143 meters, and the underwater danger factor is higher.
The members of the Blue Flag rescue team believed that the risk factor of underwater salvage was too high, and in case of an accident, not only would the body not be recovered, but the rescuers would also dieTherefore, for the sake of safety, the body of the Chongqing girl who was killed can be recovered through an underwater remote-controlled robot.
However, there is a limit to what the underwater robot can do, the Chongqing girl who died is located in Bading Lake at an underwater depth of 143 meters, the higher the underwater depth, the higher the pressure, but the gas entering the body will be dissolved in the diver's blood, and then excreted with the blood circulation.
But judging from the current situation, the Chongqing girl has been killed, and the gas in her body will not be discharged from the body, 143 meters is equivalent to 15 atmospheres, in other words, the air pressure in the body of the Chongqing girl who died will expand to more than 15 times due to going ashore, and the body will also occur because of excessive air pressure**.
The only way to recover the whole body is to do a puncture work in the water area away from the shore, and release a large amount of gas in the body through the puncture, so that the complete body of the Chongqing girl who died can be recovered ashore.
On November 21, the Blue Sky Rescue Team decided to rely on underwater robot lighting to salvage the body of the Chongqing girl who was killed.
Mr. Liu Yi's experience in diving between 140 and 200 meters, coupled with many years of rescue work experience and more than 20 experience in skylight diving, is the most suitable person to salvage the body of a girl who died in Chongqing.
On the same day, Mr. Liu Yi, a member of the Blue Sky Rescue Team, dived to 143 meters to salvage the body of the Chongqing girl who was killed, and the body of the Chongqing girl was hung on a steep slope of more than 70 meters.
Fortunately, the salvage mission was successfully completed, Liu Yi punctured the body of the deceased Chongqing girl at a distance of 105 meters from the surface, and waited for a large amount of gas to be released, and Mr. Liu Yi successfully brought the intact body to the shore.
According to the description of the other four diving enthusiasts, they agreed to return to the shore at a depth of 34 meters, and the blue sky rescue team learned from the diving watch in the hands of the Chongqing girl who was killed that the Chongqing girl had been separated from the other three teammates 3-6 minutes after the four hobby divers divedAt this time, the depth of the water was exactly 34 meters as they had agreed.
Strangely, according to the diving rules, if the diver is unfortunate enough to get separated from his teammates, he should wait for a minute, and if he does not wait for his teammates and should return to shore, then why did the Chongqing girl not return to shore after being separated from her teammates but kept diving to 143 meters?
There are two situations analyzed by the blue sky rescue team, one is that the Chongqing girl may have encountered some strange creature, she was extremely frightened in her heart, and she wanted to find her teammates urgently, and she forgot the diving rules for a while, so she kept diving north.
The other is a physiological phenomenon - nitrogen intoxication, at a pressure of 3-4 atmospheres, the nitrogen in the high-pressure cylinder will enter the human blood, dissolve with the nerve tissue, and the nerve conduction and central structure in the human body will also be weakened.
At this time, the diver may be overexcited, and the physical skills cannot give a normal response, once the situation of nitrogen drunkenness should be rescued in time, otherwise there will be a danger of death.
The girl killed in Chongqing may also have been slow to react due to nitrogen drunkenness, made a wrong judgment, dived deeper and deeper, and died because she did not receive timely rescue.
The Blue Sky Rescue Team also found that the diving watch was in a state of continuous increase in depth for a long time, at this time the Chongqing girl was almost in a state of natural fall, even if she struggled for a few minutes, she finally hung on a steep slope of 70 meters in 22 minutes and stopped divingIn other words, the Chongqing girl was already dead at the time of 22 minutes.
Epilogue
Diving enthusiasts feel the ocean and enjoy the thrill of diving in the bottomless caves, but danger also looms over them at all times, so be sure to check all the equipment before diving to ensure your safety.
It is undoubtedly a pity that a young life has ended.
So, in the face of the unfortunate death of fellow teammates, should the rest of the team members be held liable?
In fact, there are similarities with the cases of drinking at the same table that have been hotly discussed in previous years.
If a companion dies due to overconsumption at the table, or if an accident occurs on the way home after drinking, the other guests at the table are not liable.
In the face of similar cases, there are many controversies in the academic community and **, but with the increase in similar cases, there are mainly two points in the actual precedents.
One is the actor's behavior, and the other is the subjective intention and conduct of others.
In this case, if the incident was an accident, then the accompanying team members naturally did not have to be responsible for it after fulfilling their due responsibilities.
So, although the victim is a woman, she is a vulnerable group from the perspective of the general public and needs to be taken care of, but as diving enthusiasts, both of them already have diving experience.
At this time, it is no longer possible to ask others to do more to take care of the woman because she needs to take care of her.
In addition, for the whole process of diving, several people are determined in advance, and the deceased is not forced by others, and the deceased, as a person with full capacity for behavior with diving experience, can predict the danger of the behavior.
And after the accident, the rest of the team members also took corresponding measures at the first timeTherefore, there is no longer any need to be responsible for the accident of the deceased.
Everyone has only one life, and when faced with risks, we can't put our safety problems on others, but more often we have to rely on ourselves.
