If the "water ghost" on the construction site doesn't come up, the oxygen will be cut off. Why? Why didn't the people up there pull him?

Diving salvage is now a form of company, which means that professional salvage companies are registered and generally participate in some underwater operations, such as salvage, cutting and dredging, such as dredging and drainage. Many times, they have to undertake some tasks of salvaging bodies. Some drilling rigs on the construction site are broken, and the project can't be connected by itself, so they will contact these professional teams for salvage at a high price.

Of course, underwater operation is dangerous, so every time you go into the water, it is actually a test. Ordinary fishing is nothing, but this kind of on-site drilling fishing, because it is mud, has no visibility at all. No one knows the following situation except the structure of the drilling rig. Divers can only discredit the fishing bit. Of course, he can only go down when he is fully armed. The diving suit he is wearing is connected to the oxygen supply pipe.

Generally, it is not pure oxygen, but high oxygen air. The purpose of this is not only to let divers breathe, but also to create a balanced air pressure environment for underwater divers through high-oxygen air, so that divers can maintain stable pressure and avoid physical injury. To put it bluntly, it is to avoid occupational diseases such as decompression sickness.

This kind of diving, with heavy equipment and oxygen pipes, is very troublesome to work underwater. Because the following situation is complicated, it is easy to have some accidents, so it is normal to carry a knife with you. Generally, if you catch something, you can cut off the place you caught with a knife and then run away.

Of course, will the team on the ground directly cut off the oxygen supply pipe? This reality does not exist at all. It's all legends. If you cut off the oxygen supply pipe on the ground, it is a criminal offence, no different from intentional homicide, and you need to bear criminal responsibility. Normal people know this. Because oxygen is the guarantee of the life of underwater workers, if the oxygen supply above is cut off, people will die. This is intentional homicide.

So, there is no such thing. In fact, the diver was stuck in the underwater oxygen pipe and could not take it out. At this time, the diver cut the pipe himself and escaped, but people on the ground could not cut the pipe unless they wanted to bear criminal responsibility and go to jail. Generally, the cut pipes are cut by divers themselves when they are in danger. Later, people on the ground pulled the pipe and rope and found it broken, which made some people think it was the illusion that the people above cut it.
