It was a rainy day. Pen "Fun" Pavilion www.biquge.info

At noon, Yang Wenbin did not continue to read, but fell asleep.

stayed up all night in a row, and she was physically and mentally exhausted. Lying on the bed, he slept very deeply, and he didn't wake up until it was almost time for the lecture when the correspondent came to call him.

"Platoon commander, wake up, the company commander called you."

Yang Wenbin got up from the bed with a "Teng", went to the water room to wash his face, and went to the second floor, the company commander's room.

The company commander sat on the edge of the bed, and when he saw Yang Wenbin coming in, he told him: "Inform the officers and men of the whole company that in the afternoon, the first and second platoons will bring saws, axes, and ropes and assemble at the camp assembly ground." ”

Because Yang Wenbin was on duty this week, after receiving instructions from the company commander, he returned to the first floor.

There were still five minutes left until the exercise time, Yang Wenbin, whistled, "Each row, with saws, axes and ropes, prepare to assemble." ”

After hearing Yang Wenbin's shout, the squad leaders went to the warehouse to get saws, axes, and ropes.

After the drill horn sounded, the officers and men of the missile company had already assembled at the battalion assembly site!

Two cars from the battalion headquarters were already waiting there.

After Yang Wenbin gathered the personnel, he reported to the company commander: "Comrade company commander, the officers and men of the whole company have been assembled, please instruct!" Platoon on duty commander Yang Wenbin. ”

After returning the salute, Commander Ji said, "Take a break."

"Take a break!" Yang Wenbin repeated the password and returned to the end of the queue.

"Tell me!" The company commander returned the salute, "This afternoon, we will go to cut wood." To participate in the exercise, our company needed a total of 12 self-rescue trees.

It is required that in the process of logging, all personnel should obey orders and follow commands. Do not act without permission, and ensure absolute safety. ”

Then, two platoons of personnel, each got into a car.

The car left the camp and headed southwest. Slowly from the asphalt road, to the sandy road, and then to the dirt road in the countryside.

After walking for about half an hour, I came to a wooded area by the river.

There, an old man, was already waiting there.

The company commander said that this was the secretary of the party branch in the village.

The regiment had already coordinated, and they cut down twelve self-rescue trees in the village woodland.

The village party secretary shook the hand of Company Commander Ji and said: "We are a co-construction unit, and we unconditionally support the actions of the troops. Go in and find it yourself, and put whatever tree you like. ”

The company commander thanked him, and then, commanding all the officers and men of the company, got out of the car and walked deep into the woods.

Since it was summer, it had just rained two days ago, and the grass in the woods was still wet.

The company commander surveyed the thickness of the trees as he walked.

He came to a poplar tree, pointed to this poplar tree and said to Yang Wenbin and the squad leader in the platoon: "Put this tree first!" ”

And then he drew a chalk mark on the tree.

Yang Wenbin saw that this tree was relatively straight, about 20 centimeters in diameter, not tall or short, and it was really suitable for self-rescue.

Before felling, the company commander asked each platoon commander and squad leader to hold a meeting for everyone.

"Logging is easy to say, but it's actually a technical job, so you have to pay attention to safety," he said.

The method is to hold the large saw, one person holds the handle of the company, and then, at the selected root position, the saw body is sideways, pulling back and forth.

At the same time, the other person pulls on a rope that is tied to the upper part of the tree in advance to prevent the tree from falling in the direction of the tug-of-war.

While the two warriors were felling, they gently pulled in the other direction.

When a tree breaks, the trunk will naturally fall in the direction of the rope.

Then, according to the dimensions of the tracks of the armored vehicle, the trunk is sawn, and then the branches and treetops are removed, and then it is enough to carry it away.

Soon, according to the instructions of the company commander, each platoon was divided into a squad as a group. Everyone started logging.

Yang Wenbin reminded others to avoid the direction of the trees to prevent them from being hit by the trunks when they were fell.

Some time ago, when Yang Wenwu was learning to drive a tank, the instructor only talked about his basic principles and how to use the self-rescue wood, but he didn't really touch it when it was used.

When driving in the soft and muddy swamps of rice fields and forcibly crossing rivers, tracked vehicles often have silting due to poor ground adhesion conditions.

And the most realistic way to save yourself after the collapse is to rely on logs.

Tracked vehicles, after silting, should be self-rescued according to the silting situation, the surrounding environment, the existing equipment and the toilet equipment that can be used.

Log self-rescue is to use logs to improve the adhesion of tracked vehicles.

Logs, hard, uniform in thickness, 250 to 300 mm in diameter, should be about 300 mm longer than the width of the track.

When self-rescue, the log should be fixed to the track with a connecting tool.

Generally, the log is fixed with a traction wire rope connecting ring.

The specific method is to wrap a traction wire rope on the tracked vehicle on the log, and the towing rings at both ends of the rope are connected to the crawler with connecting rings. When installing the connecting ring, the connecting pin should be inserted from the bottom to the top, so that it can be removed, this method is suitable for self-rescue in the forward direction, can withstand greater traction, but is easy to damage the wire rope.

Self-rescue with logs is the most common method of self-rescue of tracked vehicles, in order to make self-rescue can be carried out smoothly, it should be noted when connecting logs:

The first point, before connecting the log, should be according to the situation of the silting of the tracked vehicle, the ground soil that is placed at the place of the logs is leveled, if necessary, the trench should be dug according to the size of the log, so that the logs are basically flush with the ground, so as to increase the adhesion of the tracked vehicle and reduce the resistance of movement.

The second point is that the logs should be placed flat. The two ends of the log should protrude the length of the outer edge of the track is basically equal, if the thickness of the two ends of the log is different, the thick end should be less prominent, so as not to pull the log obliquely, or break the log due to uneven load.

The third point is to tie a long wire rope in the center of the log, and one end of the rope is tied to the towing hook in the direction of self-rescue, so that when the tracked vehicle continues to drive after leaving the silt, the log is pulled out to reduce the difficulty of taking out the log from the silt.

Yang Wenbin saw that the logs selected by the company commander were basically generally thick at the top and bottom, and they were relatively straight, which was the most suitable wood for self-rescue.

I thought: "Don't look at the company commander, I don't usually like to talk much, but I still know a lot about the profession." ”

There were still a lot of people and a lot of strength, and it took about two hours for the whole company of forty or fifty people to cut down twelve logs. Then, take the value of the log, directly according to the length of more than 20 centimeters of the track, according to the leaf tip, and then, instruct everyone, carry the log to the side of the road, waiting to be transported.

The company commander, instead of letting everyone lift the logs into the car, hired a tractor. Then, working together, the comrades lifted the log onto the tractor and fixed it with ropes. Then, all the personnel who participated in the logging returned to the camp in the large trucks of the troops, according to the assignment at the time of arrival.
