"What did Xie Wanying say she knew?" Several former high school classmates chattered.
I don't quite believe that classmate Xie has a panacea. How to remove the slate is not a medical problem.
Who said the slate had to be removed.
"Use a jack to raise the height of the stone slab," Xie Wanying said.
This is obviously a way. If you can't move the obstacles and want to get out of space, you can change your thinking. Raising obstacles or lowering the ground level are other ways to make room.
Dr. Guan hit his thigh with his fist again, and responded at the speed of light, "I think her method will work."
Some are in favor and some are against.
Dr. Guan's approval was accompanied by a lot of doubts, such as bargaining in the vegetable market, with different opinions and endless quarrels.
"Go to hell."
"Can the weight of the stone slab be lifted with several jacks?"
"If it could stand up, the wounded could have been pulled out of the stone slab long ago. There is no way to drag it until now?"
"I started a crane, a forklift and a cutting machine here. Do you think these things are not as good as jacks?" Jacks can lift heavy things. The only problem with jacks is that there is only one point of support for the jack's working process. like
Ballet dancers are most afraid of falling when they dance with their toes. It is not because they are afraid of insufficient strength, but because they are afraid of losing their sense of balance.
A support point For a large-area object, the unequal result of the support force and the force-bearing area will cause the object to lose its balance instantly when the force is applied, and it will fall in mid-air.
It is equivalent to not being able to stand up.
In order to solve this problem, multiple jacks are required to work at the same time when using a jack to support a large-area object, so that the force can be evenly distributed by giving the object multiple support points.
At present, some of the stone slabs flying obliquely are pressed in by other landslides, and jacks cannot enter the site 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 halfway through. The consequences of power conduction in the past are unpredictable. Maybe there will be another landslide in the future, and the patient will be taken away directly.
buried.
The concerns of other professionals in the field are entirely valid.
"Tell me more." Dr. Guan didn't believe in this evil, and pointed out that he wanted to thank his classmate and continued.
Now he is a normal classmate who bets all his treasures on Xie, and he can't believe he can make a mistake.
Chang Jiawei glanced at him dissatisfiedly: Don't compete with me for compliments, please.
Xie Wanying added to explain her plan: "There is no need to prop up too high, and there is no need to prop up the entire stone slab. It is only necessary to prop up a few points to remove the operating space for the patient to perform surgery on."
After listening to her follow-up words, there was another clamor at the scene, and the opinions of the two factions were somewhat at odds.
"She's not saying it's impossible, but it's highly unlikely."
"If it can be done, wouldn't it be possible to support a few points to pull the patient out from under the stone slab?"
This requires a careful site survey to check whether Xie's words are feasible in practice. The professional firefighters quickly got down on the ground again, re-observed and evaluated the situation under the stone slab, and finally raised their hands to report to their superiors and other on-site personnel: "I thought the plan she said might be feasible. The side of the injured person's right leg
There is room to raise it slightly. "Like a large-scale disaster site like this, its landslides are all-encompassing.
