Some netizens shared
Shanghai's recent roads, rivers, swimming pools, etc
Icing photos
Netizens took photos of Shanghai's recent frozen roads, rivers, and swimming pools.
Regardless of the river surface of the Shanghai community
The scene where the ice is thick enough to walk away
Whether or not it actually happened
But seeing this picture, I can't help but ask
Is this really safe?
What should I do if I fall?
Sure enough
In Wencheng County, Wenzhou City, Eryuan Town
On the nine peaks of Zhuyang
Something like this really happened...
Woman standing on the ice to take a picture
The ice suddenly shattered......
Recently, a video of "can persuade one to be one, don't go to this icefall in Wenzhou" has been widely circulated on the Internet.
The video shows a woman taking pictures on the ice when suddenly the ice shatters and the woman falls into the icy water. The surrounding tourists let out a burst of exclamations, and her companions quickly reached out to pull her out of the ice water, and the woman finally managed to escape.
After verification, the place of the incident was Zhuyang Jiufeng, Eryuan Town, Wencheng County, Wenzhou City. Compared with the famous Wencheng scenic spot Baizhangyi, Zhuyang Jiufeng is "hidden" in the deep mountains. Recently, the scenic spot has become popular on social platforms because of its ability to shoot blockbusters that look like Nordic scenery, attracting many tourists to check in.
The video publisher "Xu Hammer Wu Lang Lang" was in Zhuyang Jiufeng on December 25, and the accident he saw also happened on the same day. She wrote in the video that as soon as she arrived at the icefall site, the ice shattered.
On the Internet, some netizens said that similar incidents have happened before (falling off the ice), and don't get off the ice at will.
Many netizens said
Be sure to improve your safety awareness
Momo: After all, the ice in the south is weak and weak, and I don't dare to walk on this kind of ice.
Even if the south is frozen, it is not thick enough to stand on people. I can only say that I am joking with my own life.
51m: I'm really glad the water down there isn't deep!
It is reported that a warning sign has been set up at the entrance of Zhuyang Jiufeng, which reads: "This scenic spot has not yet been opened, please do not visit! A staff member replied to the reporter that the scenic spot has been abandoned for a while.
Well, the ice surface that we usually see
Is it really good for walking?
According to @中国Water Conservancy news, when the thickness of the ice layer is greater than or equal to 15 cm, the ice bearing capacity can meet the needs of adults on the ice. However, the load-bearing capacity of the ice surface cannot be observed with the naked eye. Even in the cold winter season, the ice surface is unfrozen and the ice thickness is different, and once people get on the ice, there is a risk of collapse at any time.
In fact, the thickness of the ice is affected by many factors such as air temperature and water depth, water flow speed, etc., therefore, the thickness of the river ice is different, and the seemingly solid ice surface is actually not strong, it is difficult to bear the weight of the human body, even the slightest stepping or vibration may cause the ice to crack, and people are prone to fall and drowning when walking, running or sliding on the ice.
On the other hand, the ice surface that freezes on the flowing river channel will change with the amount of water, and a "vacuum" of 2-3 cm will form under the ice surface, which is very easy to break. If you accidentally fall into the icy water, you may instantly move under the ice, and the rescue will be much more difficult. In some rivers, the ice surface is mixed with aquatic plants, which hides great dangers.
The thickness of the ice surface cannot be confirmed by the naked eye, so it is not small that the risk of blindly icing on the ice is not small.
