United as one, united as one, this is not just a slogan.

The Linghai Reserve Battalion can achieve its current scale only because of the unity of the "shareholding" units. The current combat effectiveness relies on collective wisdom.

Because of this, every time when the construction workers in the Yangliu section took over their shifts for dinner, or when the personnel who went out to perform rescue missions came back for dinner, Han Yu would ask Bureau Ge to take over the "scheduling power", and he would bring his notebook to borrow the officers and soldiers' During the meal, we listened to the opinions of the officers and soldiers participating in the war on the emergency protection work.

Everyone has a task, and the construction machinery is running around the clock. It is impossible and unrealistic to convene a meeting with all the people, so we can only brainstorm in this way.

Director He was sent by his superiors to record the rescue process of the emergency rescue commando. Every time Han Yu chatted with the officers and soldiers participating in the war, he would participate and record it.

The soldiers may have been a little reluctant before, but after two or three chats, they are now very enthusiastic about speaking.

As soon as Han Yu said a few words of encouragement, a soldier raised his hand and said: "Battle Commander Han, since we are building a safe zone now, we should consider all aspects of safety."

"What specific aspects should be considered?"

"For example, the sandbag wall we are building cannot be built until it reaches the top of the embankment."

The little soldier held up his chopsticks and pointed to the "big platform" where three rollers were repeatedly rolling, and said: "The safety zone is more than ten meters high. When we build sandbags on top, we have to tie safety ropes. If people stand on it or stand on the edge, What should I do if I accidentally fall?"

Han Yu nodded: "It makes sense, continue."

"Nowadays, there are woven bags. I think we should fill more and tie more sandbag cages, and build a wall around the safety zone, which is equivalent to a guardrail, but it looks like an ancient city wall. As long as there is a wall to block it, If there is another flood in the future, people nearby will come to the safe area to take shelter, so they don’t have to worry about falling."

"Captain Han, the sandbags on the wall can not only prevent people from accidentally falling in. If there is another flood in the future, and the water level is higher than the second flood peak, embankments will definitely be built, and a large number of sandbags will be needed. When the time comes, you can come directly to the safety area to remove the sandbags on the 'guardrail'!"

"It makes sense. Your suggestion is very good. What is your name?"

"Reporting to Commander Han, my name is Liu Xiaojun."

"And you?"

"My name is Xu Jun."

"Director He, this is a very good suggestion. Please remember it."

"yes."

"Battle Commander Li, since it is a good suggestion, we must adopt it. Please organize its implementation."

"yes!"

…

It is better to have your suggestions adopted by your superiors and have your name recorded by Director He than to do a hundred good deeds. Maybe you will be rewarded and it is not impossible to join the party.

Liu Xiaojun and Xu Junle were so happy that they quickly put down their lunch boxes and saluted Han Yu, Officer He and the battalion commander.

Li Shousong was very happy and proud of his subordinates. He looked at the crowd with a smile and said: "Comrades, we are having a Zhuge Liang meeting right now. If you have any good ideas, please tell us as soon as possible. As long as it is conducive to rescue and rescue efficiency, Han The battalion commander will adopt it, and every officer will write it down."

Du Yuan, who had just returned from grouting, wanted to give advice, but he thought that unlike his comrades, he was on a business trip and had to listen to the head of the "Hong Kong Garrison" and the old squad leaders. If he gave advice to the "Hong Kong Garrison" Will the chief and old squad leaders be unhappy...

There are not many bricklayers.

Han Yu was deeply impressed by him. Seeing that he was hesitant to speak, he pointed at him and asked with a smile: "Du Yuan, do you have any good suggestions?"

"me……"

"What am I? Battalion Commander Han is so busy at work that he doesn't feel ashamed to ask. If you have anything to say, just say it. Don't be coy!"

"yes."

Du Yuan calmed down and said cautiously: "Captain Han, I think we can improve the efficiency of grouting to protect people from danger of cracking. The mud we use is not good."

The danger of cracking in grouting protection is also a new thing for the Linghai Reserve Battalion. Before coming here, not only had I never experienced emergency protection before, I had never even seen it.

The technicians from the underwater engineering company who came from their hometown have rich experience in protecting the underwater parts of ships and underwater reinforced concrete buildings, but they have never played with mud and are not very good at grouting and protecting cracked embankments.

Industry specializing in surgery.

The young man was a plasterer before joining the army. He is indeed more professional than others at this job.

Han Yu looked at him with a smile and said, "Be specific."

"First of all, it's mud. We dig it on site and mix it with water on site. There are a lot of impurities in the soil. Soil is different. Some soil is sticky and some is sandy. Anyway, we dig and mix whatever soil we have. The slurry is mixed with too sandy soil, and the effect will definitely not be as good as that of clay soil."

Du Yuan licked his lips and continued: "And to protect the risk of cracking, it is not enough to pour grout once. It was filled the day before yesterday and it will be filled again today, and it may be continued tomorrow. The grout used is different every time. After it dries, It’s very possible that it won’t stick together, and the cracks may appear to be blocked on the surface, but there will be faults inside, and they will crack again over time.”

This kid is really good at playing in the mud!

Li Shousong and Director He subconsciously looked at Han Yu, wondering what Han Yu would say.

Han Yu was also surprised and said in deep thought: "Xiao Du, what you said makes sense. How do you think we can solve this problem?"

"Captain Han, I help people lay bricks and build houses in my hometown. When mixing cement slurry, I have to sift the yellow sand first. I think if you want to really pour the slurry and let the poured mud work, you must First find the most suitable soil, sift it through a sieve to remove all impurities, and then mix it with clean water that is free of aquatic plants and rotten leaves."

"Go on."

"The finer the soil, the better. I've seen the quality of the soil here, and you can't use all clay. After all, when you pour it in, it will become one with the embankment when it dries. Camp Commander Han, I'm not very good at talking, anyway. The soil used must be of the same quality as the soil used in the embankment.”

This directly involves emergency rescue!

This is much more important than building a "wall" around the safe zone.

All the officers and soldiers, including Li Shousong, were shocked. They couldn't believe that the "little mason" was doing the same thing. Commander Han was taking notes.

"Okay, continue."

Han Yu put down his pen and looked at Du Yuan with encouraging eyes.

Du Yuan said everything he wanted to say, there was no need to hide it anymore, and continued: "Our current grouting holes are drilled directly, which is similar to piling. The steel pipe is so thick, drilling it like this will affect the structure of the embankment, and Every time I hit it, I have to pull it out and clean the soil in the steel pipe, which is very troublesome.”

"Then how to make a hole?"

"You can no longer drill holes. You should drill holes. Use a long small drill bit to drill into the embankment. A hole of two or three centimeters is enough. You need to drill more holes around the cracks. It is best to drill one every twenty or thirty centimeters. Grouting holes. But I don’t know if there is such a drill. Even if there is, how to grout it is another problem. Today’s grouting pumps are so big and the grouting holes are so thick. Where can I find a small pipe? How can I pump grouting holes if I find a small pipe? Orally.”

"I'll ask the mechanical maintenance team to find a solution for the drill bit, grouting pipe and how to connect the grouting pump. I believe there will be a solution. You continue."

"After the grout is filled, the holes and cracks must be sealed after the grout dries. It is best to add some cement to the sealed grout."

"Sealing is indeed very important, Xiao Du. Now there is another problem. We have rushed to protect it, but how do we know whether the grouting and rush to protect it has worked?"

"It's easy. As long as there is water leakage, it's easy to check."

"How to check?"

"Didn't the diving team seal the underwater cracks first? After we have filled the grout a few times and the grout has dried, we will ask the leader of the diving team to go down and clean out the mud from the cracks and pour water into the water. Pour in a few more bottles of ink and look on the embankment and behind the embankment. As long as there is black water, it means there are still places where grout has not been filled. If you don't see black water seeping out, it means the grouting has worked."

"You can check it even on a rainy day."

"Yes, it's just a bit of waste ink. One bottle is definitely not enough. The river water is flowing, so a lot of ink needs to be poured into the water."

The masters are among the people!

Han Yu realized that he had met a talented person, looked at him with a smile and asked: "Then how can we improve the efficiency of grouting protection?"

Du Yuan pointed to the boat anchored on the river: "The soil quality of the levees here is almost the same. We can dig more and sieve more soil near here, and fill it with woven bags first like filling sandbags for loading. There are several people on the boat. The cabins can be filled with soil in one cabin, clean water in another cabin, and mud mixing in the other cabin.”

Han Yu smiled and asked: "Prepare more deeply processed soil and clean water, and then mix it at the rescue site?"

"Mud is actually the same as cement slurry. It dries easily if mixed too early."

"continue."

"If the grouting pipe can be changed into a small pipe and can be connected to the grouting pump, the grouting pump and diesel engine can also be moved onto the ship. Drive to the place where grouting is needed and wait for the hole to be drilled. Then start the machine on the ship for grouting. Use There’s no need to move the grout pump and diesel engine ashore.”

Du Yuan thought for a while and then emphasized: "Captain Han, grouting is different from other things. It is not just done once. I estimate that to protect a dangerous situation of cracking, it will take at least three or four times. It must be divided into several parts." After a few days of irrigation, this is the only way to improve efficiency."

Talents must be reused!

Han Yu weighed it up, stood up and said: "Comrade Du Yuan, from now on, you are the leader of the grouting team of our emergency rescue commando team! I will find you a self-propelled boat, that is, a powered boat. I will equip you with one An experienced driver and a crew, and a mechanic for you.”

"Captain Han, I am a new recruit, I can't be the squad leader..."

"I say you can do it, you can do it, and you are indeed good at it!"

Han Yu walked over and patted his arm, then turned back and asked, "Battle Commander Li, what do you think of Director He?"

The team leader of the "Hong Kong Garrison" is either a project manager or a formal cadre, or a technical master. How can a little plasterer be a team leader!

Li Shousong couldn't believe his ears and didn't know how to answer, so Director He smiled and said, "I have no objection."

"Captain Li?"

"I...I don't have any objection either."

"Since you have no objection, please help Comrade Du Yuan select, fill and even move the soil he needs when organizing the filling and packing of sandbags."

"yes!"

"Battle Commander Li, as of half an hour ago, there were dozens of cracks on the dry embankments and river embankments on Guang'an Gong's side. This means that the grouting team's next rescue mission will be very heavy. The soil he needs is It’s a priority, and you must ensure it is in place.”

"clear."

"Comrade Du Yuan, let's go, I'll take you to find the comrades from the mechanical repair team. Take the time to find a way to see how we can complete the modification of the grouting pump as soon as possible."

"yes!"

…

Is there any mistake? The "mason" actually became the squad leader!

The officers and soldiers of the 132nd Regiment looked at each other in shock. They didn't come back to their senses until Han Yu took Du Yuan away.

"Comrades, have you seen that as long as you have good ideas and good methods, your superiors will adopt them? I hope everyone will follow Du Yuan's example and use their brains and talents when performing the tasks assigned by their superiors, and not just look at stupid things. Dry."

Director He waved his arms and said in a measured tone: "Of course, Comrade Du Yuan has Comrade Du Yuan's professional advantages. The good methods and ideas he can come up with are definitely beyond our imagination. But we can think of other things, such as Comrade Liu Xiaojun and Xu Xu Comrade Jun, the suggestions they just put forward are also very good, and the superiors have also adopted them. Let us congratulate Comrade Liu Xiaojun and Comrade Xu Jun with warm applause!"
