What did Xie Wanying say she knew?" Several former high school classmates chirped.
I don’t quite believe that Mr. Xie has a magic solution. How to remove the stone slab is not a medical problem.
Who said the slabs must be moved.
"Use a jack to raise the height of the stone slab." Xie Wanying said.
This is obviously a way. If you can't remove the obstacles and want to make space, you can change your mind. Raising the obstacles or lowering the ground height are other ways to make space.
Dr. Guan hit his thigh with his fist again, and responded at the speed of light: "I think her method will work."
Some people are in favor and some are against it.
Dr. Guan's approval was accompanied by a lot of doubts. For example, people had different opinions on bargaining in the vegetable market and kept arguing.
"Fuck you."
"How many jacks can the stone slab be lifted up with such a heavy weight?"
"If I could hold it up, I would have been able to pull the wounded person out of the stone slab long ago. How can we drag him until now and there is nothing we can do?"
"The crane, forklift and cutting machine are here. Do you think these things are inferior to jacks?" Jacks can lift heavy objects. It is said that they can lift "heavy" things. In theory, a jack with unlimited load capacity can be designed. Jacks
The only problem is that there is only one support point for the jack's operation process. For example
Ballet dancers are most afraid of falling when dancing on pointe. They are not afraid of insufficient strength, but are afraid of losing their sense of balance.
For a large-area object at a support point, the result of the unequal support force and force-bearing area will cause the object to lose its balance instantly when it is stressed and tip over in mid-air.
It's equivalent to being unable to stand up.
In order to solve this problem, when using jacks to support objects with a large area, multiple jacks are required to work at the same time, giving the object multiple support points to evenly distribute the force.
At present, part of the stone slab that flew out obliquely is pressed inside by other landslides, and jacks cannot be used to support these invisible parts. People can only use jacks to support the exposed stone slab parts. In this case
The biggest fear is that other accidents will happen halfway through. The consequences of the force transmission are unpredictable. Maybe there will be another landslide later and directly kill the patient.
Buried.
The concerns of other professionals on site were entirely valid.
"You can tell me more." Dr. Guan didn't believe this evil and pointed out that he wanted to thank his classmate for continuing.
Now, as usual, he bets all his money on classmate Xie. He doesn't believe he can make a wrong bet.
Chang Jiawei glanced at him dissatisfiedly: Please don't compete with me to praise others, okay?
Xie Wanying added about her plan: "There is no need to prop it up too high, there is no need to prop up the entire stone slab, it only needs to be propped up a few points to open up the operating space for the patient to perform surgery."
After hearing her follow-up words, the scene started shouting again, and the two groups had somewhat irreconcilable opinions.
"What she said is not that it is completely impossible, but it is very likely that it cannot be done."
"If it can be done, wouldn't it be possible to hold up a few points and pull the patient out from under the stone slab?"
This needs to be carefully investigated on site to check whether Xie's words are feasible in concrete practice. The professional firefighters quickly lay down again, re-observed and evaluated the situation under the stone slab, and finally raised their hands and reported to their superiors and other on-site personnel: "
I thought the plan she mentioned might be feasible. The injured person’s right leg
There is room to raise it slightly." At a large disaster site like this, the landslides are all-encompassing...
