"T-type rescue is a rescue method to rescue people trapped in the sand dunes and isolated islands in the middle of canyons or rivers, which is mainly suitable for situations where the height difference between the two banks is small and the rescue depth is not large!

In the case of mountain streams, we usually use trees as fulcrums at both ends, and cities as pillars.

The second is the displacement system, which is divided into transverse and longitudinal ......"

The process of explaining is very boring.

But, for every firefighter, it's something new, something that saves lives.

To be precise, it's something that saves someone's life.

A new technology may be able to give them access to spaces that they couldn't access before.

However, in the view of Fang Huai, who is knowledgeable, this set of traditional T-shaped rescue still has many defects, although it saves equipment and manpower, but the efficiency is also lower.

Moreover, the safety equipment is outrageously small, obviously a rope is required to be responsible for traversal movement, a rope is responsible for longitudinal movement, and there is no professional metal force component plate, and the rope of traversing and falling is actually a four-bow knot made of a rope to serve as a force component.

Fang Huai was very powerless to complain.

It is necessary to engage in both advanced T-type rescue and this kind of land mine.

If you don't have double rope protection, you have to prevent the rope sleeve from pulling down more and it will be knotted, and you have to use a stretcher to pull someone up below, focusing on Peter Pan, right?

A reasonable rescue system can be replaced with equipment, so it should be replaced by equipment!

However, Fang Huai also knew in his heart that it would probably take many years for these equipment to be perfect, and he could only solve the problem of existence first, and then solve the safety problem.

If something really happens, it's the same as when you can only use three sets of waist knots with grinding crotch to protect you, and you have to use it.

Firefighters in these years, it's hard.

The rope technology of China's fire rescue team started late, and the spiral rope technology of Japan in the last century was introduced around 2000, which began to fill the gap in domestic fire rope technology.

In some exercises, I also began to learn.

But that thing, it's really a spell of technology, the main one is simple, less equipment, less protection, everything is solved by ropes, the proficiency required is very high, and the latest protection method is also based on SRT (single, single rope protection).

Without coordinated protection, you can't make mistakes, otherwise it's hard to spell the eight characters.

It was not until the past two years that Hong Kong took the lead and began to contact Western rope technology, but there was still a lack of experience in DRT (double rope protection) and multi-person collaborative operation.

The concept of rope technology in Japan and the West, just like the comparison between Japanese cars and virtue cars, one is light and fuel-efficient, and the other is safe to carry, you can't say that light is not good, but if you really want to crash, you will still regret not buying more insurance.

The main thing is the lack of equipment.

DRT protection, a lot of equipment, expensive, requires a lot of personnel, however, safe, high fault tolerance.

Don't underestimate those rope equipment, very precise, good things are also very expensive, really to the rescue, a lock is wrong, there will be a big problem immediately, the equipment consumption is also fast, need a lot of inventory.

Moreover, China's rescue rope technology training institutions are complicated and chaotic, with different technical categories, and lack strict specifications for the qualifications of training institutions.

I started late, and most of the things I used were other people's things, and I didn't work to use them, so I had to spend money to hire someone to teach them.

The design ideas are people's, and many of the things in them have patents, and some training fees are not costly.

However, today I didn't suffer to the end, and I brought the rescue belt.

To be honest, as far as the rope is concerned, it is difficult for ordinary people to tie a shoelace smoothly, and if you touch such a complex rope system, it is a problem for ordinary people to understand it, let alone play.

But fortunately, after so many years, after all, it is an important equipment to save life, and it is also an assessment item, everyone touches a lot, and the comprehension ability of the rope is not bad, and soon the whole system is disassembled into protection, traction, braking, and a good T-shaped system, one by one.

Then, take the rope and all kinds of locks, pulleys, and hit them one by one.

When I listened to the class, the pot was full of rat droppings, and when it came to practice, I became a good student.

Fang Huai is different, he is the kind of person who wants to take the Tsinghua exam, and after class, he likes to take a few difficult questions that he carefully selects to embarrass the teacher.

"Raven, make a double-strand figure-eight knot at one end of this conveyor rope, hang it with a safety hook, connect it with the hole below the side of the component rope near the opposite bank, and connect the single pulley with a safety buckle in the hole corresponding to the component rope, right?

The above lock, is it a good point to use self-locking? ”

Raven: "Yes, yes, there are self-locking ones, go get them in the car." ”

"Since it is a single rope protection, the force component plate... Component rope, on it, is it possible to add another main lock? ”

Raven: ...

You seem to be a bit of a troublemaker.

"It's mainly about understanding the principle."

Fang Huai: emm...

"In principle, you also talked less about some safety details, one is that ID must add friction lip when releasing the rope, and the other is that each rope must be left when erecting the lifeline, so as to facilitate the movement of the position, this operation is too complicated, there may be more than these, I am not too clear, there are too many safety precautions, I suggest that the construction precautions get a booklet."

Raven: "...... It's okay, you can make a booklet for you. ”

"Well, you've done it and I'll take a look at it for you, add up."

Raven: ???

Aren't you not quite clear?

"Why don't you show it again?"

Hu Peizhou next to him finally spoke: "No. 1 will demonstrate first, I have already set it." ”

Fang Huai looked left and right: "Where is your equipment box?" I'll look for it and see if I can add some protective equipment. ”

The surroundings are so numb.

He instructed the instructor and forget it!

It's such a complicated set of things, let them learn it overnight, without a dozen or twenty operations, it is impossible to fully master it, that's it, he has to add!

……

"I rub, so fast?"

Everyone was amazed.

Fang Huai's operation was not only fast, but also different from what they had just learned.

"I'm rubbing, how can your triple force system be so complicated than ours?"

Fang Huai smiled and tried the rope.

If you don't do something, you won't, how can you pretend to be a B?

"This is a five-fold force system, adding an anchor point, on the basis of three times the force, using a chicken claw rope plus a pulley, 3 plus 2, it is a five-fold, five-fold force is not difficult to play, there are two ways to play, if there are double pulleys, it is much simpler, and the chicken claw buckle also has a mechanical, a full set of machinery, it is not so troublesome to take five times the force."

"What are you doing with such a big deal? Are you afraid that you can't pull it? ”

"The triple force system is less than three times the force, the rope walks through the pulley and ID, the force will have friction loss, and the loss is not small, there are conditions, it is bigger and more convenient."

Fang Huai said, and slowly made a four-set bow, the system knowledge is to use the component plate, this knot is the only thing he has learned.

Soon, all the T-rope bridges were erected, and all the locks were put on the shelves.

"Hmm—" The raven nodded calmly, actually very surprised in his heart.

But, I just want to find fault with him.

"It's fast, it's all right, it's this bow, it's a little ugly."

Fang Huai's mouth was crooked, wanting to curse.

Nima, how do I know you don't even have a special metal force plate?

Hu Peizhou looked at his operation, and he was sure in his heart that this Fang Huai was not just talking on paper, and his practical ability was also very strong, this T-shaped rescue rope system, they had used it so many times, but the operation was not as accurate and fast as Fang Huai.

"Now announce the subject, in the mountain stream, there is a tourist who has fallen, and now his leg is broken, and the person is in a coma, No. 1, get on the rope when you are ready! The others, according to the rope pulling method taught by Professor Raven just now, sent him to the designated location! Give you one minute to prepare, two minutes to rescue, and you have to get people back! The timer begins! ”

After the order, a logistics staff here ran frantically to the bottom of the col, and when he was about to arrive, he immediately limped up, and just like that, ouch oooh screamed.

Old actors.

Others were stunned.

I wipe, pull the rope people are not arranged?

And it began?

Fang Huai found out that something was wrong.

This goods made it difficult for him.

yelled, "What are you doing in a daze? Serial ...... Number 26! Go to the opposite side, pull the horizontal, 20th, 11th, pull the longitudinal, I call it to put it! ”

A group of people immediately rushed to their positions.

Fang Huai looked at Hu Peizhou, who was smiling at the corner of his mouth, and stretched out his hand:

"Broken legs, what about splints? Two minutes, ready-made? ”

This goods are yin, and they also hide a "leg fracture", and they don't take the initiative to provide medical equipment.

However, you think I'm deaf and can't hear?

Hu Peizhou's smile disappeared at this time, and he waved behind him, and a logistics officer brought a barrel of splint and threw it to him.

"Next!"

Fang Huai took it, a little speechless, and stretched out his hand again.

"Bandages! Bandage! What to play? Take the same thing? ”

The bandages were thrown over.

Over there, even the order has arrived.

Fang Huai immediately raised his hand: "Okay!" ”

"Start the rescue!"

Hu Peizhou shouted, and Fang Huai rushed out holding the stretcher fixed on the rope.

"26, pull the rope! Fast! ”

A wave of traction came immediately.

"Vertical, follow along! … Slow down, slow down! Hurry up laterally! Make sure you land in the area! ”

Fang Huai roared, leaning towards the wailing logistics soldier as if he were playing Wia.

Everyone ran to the edge of the mountain col to observe Fang Huai.

Falling down, it is only a few meters, but on the horizontal side, there are more than ten meters, Fang Huai is afraid that the landing area is not right, and constantly speaks out to guide the rope.

"Number 26! Horizontally, a little faster! Hurry up! Vertical first stop! … Okay, okay, put it away! ”

Fang Huai's landing area was only half a meter away from the man.

Run to the man.

But, I can't squat down.

The slope of the col blocked the view, and the two who pulled the longitudinal rope could not see him now, and they did not dare to put the rope completely, so they left some strength.

However, on the 20th and 11th, the two runners-up in the national competition, plus a five-fold force system that Fang Huai could not live by himself, the two of them only used a little force to lock him firmly.

The stretcher can't be pressed to the ground.

Fang Huai squatted down desperately, and he couldn't squat down, not to mention Hu Peizhou, even Lin Chong laughed.

"Release! I'll rub, I'll tell you all to go! ”

Fang Huai let out a speechless howl, and the rope was finally loosened.

The man on the ground was still laughing wildly just now, and as soon as Fang Huai approached, he immediately began to scream.

"Oops... Oops......"

Fang Huai angrily grabbed his leg, clamped the splint, and the bandage swished around a few times, tying a dead knot.

"Get on the stretcher!"

The man also didn't cooperate: "Can't get on!" I hurt my leg! Oops..."

I'll rub it, Lao Tzu can't handle the two earth cows above, and he can't handle you?

Fang Huai picked up the "wounded" with both hands, picked him up directly, and threw him into a stretcher.

"Bang".

"Oops! No way! ”

Now, that person is really ouch.

"Lalala! Ascent and lateral traction together! ”

Fang Huai fixed the safety buckle of the stretcher, and with a loud roar, the height went up with a whoosh.

The horizontal hadn't pulled him far, the vertical had already pulled him to the top, and even flicked it, which shocked Fang Huai.

Nima, it's a force component made of rope sleeve on top! It's going to collapse in a while, and it's four or five meters high when it falls, so don't really make a wounded person tonight!

Hurriedly shouted: "Okay, okay! Don't pull it in portraits! ”

"Whew! Oh! I'm going to fall! "That guy on the stretcher is howling so much.

But there was laughing: "This five-fold force is really bull B!" I just used a little force to pull him up! ”

When I came back, I was swaying all the way, and everyone was applauding.

"Cow B!"

The first one went down, the rope bridge was successfully built, and the task was completed on time, and everyone was very convinced.

Fang Huai is a black line.

Damn, I didn't pretend to be, I'm so frightened!

"Squadron Hu, how much time?"

Hu Peizhou glanced at the stopwatch in his hand and said to the onlookers.

"Hmm... One and a half minutes! Perfect demonstration! Pay attention to what just happened! Logistics untie! Next, get ready to go! ”

As he spoke, facing Fang Huai, he pointed to a tent that had been set up: "Follow me!" ”

Fang Huai knew that he was going to talk about business, so he untied the protection, took off his harness, and followed him to the tent.

The buddy on the ground was shaken back by a stretcher all the way, and finally landed at this moment, sat up and began to howl:

"Report! He abused the wounded! ”

(I finally finished writing, and I won't write it in the middle of the night anymore, and my eyelids are about to drop)
