"What did Xie Wanying say she knew?" several former high school classmates chattered.
I don't quite believe that Mr. Xie has a magic solution. How to move the stone slab is not a medical problem.
Who says the slabs must be moved?
"Use a jack to raise the height of the stone slab." said Xie Wanying.
This is obviously a solution. If you can't move the obstacle and want to make room, you can change your thinking. Raising the obstacle or lowering the ground are other ways to make room.
Doctor Guan hit his thigh with his fist again and responded at lightning speed: "I think her method will work."
Some people are in favor and some are against.
Along with Dr. Guan's voices of approval were a number of doubts, just like the endless arguments and divergent opinions in the vegetable market.
"What the hell."
...
...
"Can a slab this heavy be lifted with just a few jacks?"
"If we could hold it up, we could have pulled the wounded out from under the stone slabs long ago. How could it have been delayed until now and there was nothing we could do?"
"Start the crane, forklift and cutter here. Do you think these things are not as good as the jack?"
A jack can lift a lot of things. It is said that it can lift any weight. In theory, a jack with an infinite load capacity can be designed. The only problem with a jack is that it has only one support point in its operation process. For example, when a ballet dancer dances on pointe, the most fearful thing is falling. It is not because she is afraid of not having enough strength, but because she is afraid of losing her sense of balance.
For a large object, the inequality between the supporting force and the area under force at a supporting point will cause the object to instantly lose balance and fall in mid-air when the force is applied.
It's like being unable to hold up.
To solve this problem, when using jacks to support objects of large areas, multiple jacks are needed to work simultaneously to provide the object with multiple support points so that the force can be evenly distributed.
At present, part of the stone slab that flew out obliquely is pressed inside by other landslides, and the jack cannot enter to provide support for these invisible parts.
People could only use jacks to support the exposed slabs, but the biggest worry was that something unexpected might happen halfway through. The consequences of the force being transmitted were unpredictable, and a subsequent landslide might bury the patient.
The concerns of other professionals on the scene are completely valid.
"Tell me more." Doctor Guan didn't believe it and pointedly asked Xie to continue.
Now he is placing all his bets on Xie as usual, not believing that he can make a wrong choice.
Chang Jiawei glanced at him with dissatisfaction: Please don't compete with me for praise.
Xie Wanying added her plan: "It doesn't need to be raised too high. It doesn't need to prop up the entire stone slab. It only needs to be raised a few points to make room for the patient to undergo surgery."
After hearing her follow-up words, there was another commotion at the scene, and the two factions had opposing views.
"It's not that it's not possible, but it's very likely that it can't be done."
"If we can do that, can't we also support a few points and pull the patient out from under the stone slab?"
This requires further careful on-site investigation to check whether what Xie said is feasible in practice.
The professional firefighter quickly lay down again, re-observed and assessed the situation under the stone slab, and finally raised his hand to report to his superiors and other on-site personnel: "I think the solution she mentioned may be feasible. There is space on the side of the injured person's right leg that can be slightly raised."
At a large-scale disaster site like this, the landslides are all-encompassing.
