What did Xie Wanying say she knew? ” Several former high school classmates chirped.
I don’t quite believe that Xie Xie has a magic solution. How to remove the stone slab is not a medical problem.
Who said the slabs had to be moved.
"Use a jack to raise the height of the stone slab." Xie Wanying said.
This is obviously a solution. If you can't move the obstacle and want some space, you can think differently. Raising obstacles or lowering floor height are other ways to free up space.
Dr. Guan hit his thigh with his fist again and responded at the speed of light: "I think her method will work."
Some were in favor and some were against.
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 loads". In theory, a jack with unlimited load capacity can be designed. The only problem with the jack is that there is only one support point for the jack's operating process. like
Ballet dancers are most afraid of falling when dancing on pointe. It's not just a lack of strength, it's a fear of losing their 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 diagonally is pressed inside by other landslides, and the jack cannot be used to support these invisible parts. People can only use jacks to support the exposed stone slabs. In this case, they are most afraid of other accidents happening halfway through. The consequences of the power 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.
"Tell me more." Dr. Guan didn't believe this and pointed out that he wanted to thank his classmate for continuing.
Now, as usual, he bets all his money on Xie, and he doesn't believe he can make a wrong bet.
Chang Jiawei glanced at him dissatisfied: Don't compete with me to praise others.
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 were somewhat at odds with each other.
"She's not saying it's completely impossible, but it's very likely that it won't be possible."
"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 requires careful on-site investigation to check whether Xie’s words are feasible in concrete practice. The professional firefighter quickly lay down again, re-observed and evaluated the situation under the stone slab, and finally raised his hand and reported to his superiors and other on-site personnel: "I thought the plan she mentioned might be feasible. The injured person's right leg side
There is room to raise it slightly. "In a large-scale disaster scene like this, the landslides are all-encompassing. .
