Binjiang Police Affairs-Chapter 970 - 643: Brainstorming!

United in purpose and with unyielding determination, this is not just a slogan.

The current scale of the Linghai Reserve Camp relies on the unity of its "stakeholder" units. The current combat effectiveness relies on collective wisdom.

Because of this, whenever the personnel at the Yang Liu section change shifts to eat, or the personnel on emergency rescue missions come back to eat, Han Yu always asks Director Ge to take over the "dispatching rights", while he brings his notebook to listen to the participating soldiers' opinions on rescue work during their meals.

Everyone has a task, and the construction machinery runs non-stop 24 hours a day, making it impossible and unrealistic to convene everyone for a large meeting. This is the only way to gather opinions and intelligence.

Staff He is dispatched by his superiors to record the emergency rescue assault team's rescue process. Every time Han Yu chats with the participating soldiers, he participates and takes notes.

The soldiers were initially somewhat reserved, but after two or three chats, they are now eager to speak.

Just after Han Yu encouraged them a bit, a soldier raised his hand and said, "Camp Commander Han, since we are now building a safety zone, we should consider every aspect of safety."

"Specifically, what aspects should we consider?"

"For instance, the sandbag wall we are building shouldn't just stop at the top of the dam."

The young soldier pointed with his chopsticks to the "large platform" being repeatedly compressed by three road rollers and said, "The safety zone is over ten meters high. We need to tie safety ropes when stacking sandbags upward. What if someone accidentally falls while standing on the edge?"

Han Yu nodded, "Makes sense, go on."

"There are plenty of woven bags now. I think we should fill more, bind more sandbag cages, and stack a wall around the safety zone, like a guardrail, but resembling ancient city walls. As long as there's a wall blocking, if there's another flood in the future, the nearby people seeking refuge in the safety zone wouldn't have to worry about falling off."

"Camp Commander Han, the sandbag wall doesn't only prevent the public from accidentally falling. If there's another flood, and the water level is higher than the second flood peak, a sub-dam will definitely need to be built, requiring a large number of sandbags. At that time, we can directly dismantle the sandbags from the 'guardrail' in the safety zone!"

"Makes sense, your suggestion is very good. What's your name?"

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

"And you?"

"My name is Xu Kejun."

"Staff He, this is an excellent suggestion, please make a note of it."

"Yes."

"Camp Commander Li, since it's a good suggestion we need to adopt it. Please organize and implement it."

"Yes!"

...

Having a suggestion adopted by the superiors and having your name noted by Staff He is better than doing a hundred good deeds, it might even earn commendation or the possibility of joining the Party.

Liu Xiaojun and Xu Kejun were elated, hastily putting down their lunch boxes to salute Han Yu, Staff He, and the Camp Commander.

Subordinates making good progress made Li Shousong very happy and proud, he smiled at everyone and said, "Comrades, we're now holding a Zhuge Liang conference. If you have good ideas or suggestions, speak up quickly. As long as it benefits the rescue efforts and improves the efficiency, Camp Commander Han will adopt them, and Staff He will write them down."

Du Yuan, freshly back from grouting, wanted to offer his suggestions, but considering that he was different from his comrades as he was on official duty and needed to listen to the Hong Kong Garrison commanders and old platoon leaders, he hesitated worrying if his suggestions might upset them…

There aren't many Little Bricklayers.

Han Yu had a strong impression of him; seeing him hesitate to speak, Han Yu pointed and asked with a laugh, "Du Yuan, do you have any good suggestions?"

"I… I…"

"What do you mean 'I'? Camp Commander Han is so busy yet he humbly seeks advice from others. Just say what you have in mind, no hemming and hawing!"

"Yes."

Du Yuan steadied his mind and cautiously said, "Camp Commander Han, I think we can further improve the efficiency of our grouting emergency response to cracking issues. The slurry we're using isn't ideal."

Responding to cracking issues through grouting is a novel thing for Linghai Reserve Camp, before arriving here they had neither handled nor seen this before. 𝑓𝑟ℯ𝘦𝓌𝘦𝘣𝑛𝑜𝓋𝑒𝓁.𝑐ℴ𝓂

The underwater engineering company technicians from his hometown are experienced in the underwater parts of rescue ships and underwater reinforced concrete structures but have never worked with mud. They are not very proficient in grouting emergency responses to cracking dikes.

Every profession has its specialty.

The young man was a bricklayer before joining the army, so he is indeed more professional at this than others.

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

"First of all, the slurry. We're digging on site and mixing it with water right there. The soil has a lot of impurities. Not all soils are the same. Some soils are sticky, while others sandy. Essentially, it's whatever soil we dig, we mix it as the slurry. Slurry mixed from sandy soil, when poured, won't be as effective as that from clay."

Du Yuan licked his lips and continued, "And the cracking issue isn't solved by just one grouting. We might have to grout again today if we did it yesterday, and possibly again tomorrow, with the slurries varying each time. Once it dries, there's a chance they won't bind together; although it looks filled superficially, there might be layers inside which could crack again over time."

This kid has taken mud play to a higher level!

Li Shousong and Staff He instinctively looked at Han Yu, wanting to know how he would evaluate this.

Han Yu was equally surprised and pondered, "Xiao Du, you have a point. How do you think we should solve this problem?"

"Camp Commander Han, back home, when helping people build and lay bricks, we sift the yellow sand before mixing it with cement slurry. I think to effectively grout and make the slurry work, we should find the most suitable soil, sieve it to remove the impurities, and mix it with clean water free of weeds and rotten leaves."

"Go on."

"The finer the soil, the better. I've checked the soil quality here; we can't use only clay; once it dries, it needs to integrate with the dike. Camp Commander Han, I'm not very good with words, but essentially, the soil used must be consistent with the dike's soil quality."

This directly involves emergency protection!

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

Including Li Shousong, all the soldiers were shocked, couldn't believe "Little Bricklayer" had a complete set of plans, even General Han was taking notes.

"Alright, continue."

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

Du Yuan thought to himself, what's said is said, no need to hold back anymore, and continued, "Our current grouting holes are directly drilled down, similar to piling. The steel pipe is so thick, drilling it directly affects the dam structure, and every time you drill down you have to pull it out to clean the soil inside the pipe, very troublesome."

"So how to drill the hole?"

"No more drilling, should use a drill bit, use a long small drill bit to drill into the dam, a few centimeters thick is enough. Drill more around the fractures, preferably drill a grouting hole every twenty or thirty centimeters. But I don't know if there are such drill bits, even if there are, how to grout inside is another problem, now the grouting pump is so big, the grouting mouth so thick, where to find small pipes, and how to connect them to the grouting pump mouth."

"Drill bits, grouting pipes, and how to connect to grouting pumps, I will have the repair team figure it out, I believe there will definitely be a way, you continue."

"Once the grout is done, when it dries, all those drill holes and fractures need to be sealed, better add some cement to the sealing grout."

"Sealing is indeed important, Xiao Du, there is another issue, we have done the protection, but how do we know if the grouting protection has been effective?"

"This is simple, any leakage or seepage can be checked easily."

"How to check?"

"Didn't the diving team first block the underwater leaks? After we grouted a few times, when the grout we poured dries, we invite the diving team's commander to go down and clean away the blocking mud, pour several bottles of ink into the water, we observe from the dam and behind the dam, seeing black water indicates some areas didn't get grouted, no black water means the grout worked."

"Even on rainy days it can be checked."

"Yes, just a bit of ink wasted, one bottle definitely not enough, river water is flowing, need to pour a lot of ink."

The masters are among the people!

Han Yu realized he had encountered a talent, smiled at him and asked, "Then how can we improve the efficiency of grouting protection?"

Du Yuan pointed at the boat anchored on the river: "The soil quality of the dam here is about the same, we can dig more nearby, sift more soil, like filling sandbags, grout them into woven bags and load the ship first. There are several cabins on the ship, can load one cabin with soil, one with clean water, one used for mixing slurry."

Han Yu laughed and asked, "Prepare more processed soil and clean water, and mix on site at the emergency protection area?"

"Slurry is actually like cement slurry, if mixed early it dries easily."

"Continue."

"If the grouting pipe could be modified into small pipes, connected to the grouting pump, could bring the grouting pump and Diesel Engine onto the ship too. Sail to the protection area, once the hole is drilled, start the machine on the ship to grout, no need to move the grouting pump and Diesel Engine onto the land."

Du Yuan thought for a while, then stressed: "Han Camp Commander, grouting is not like other things, not done after one session. I estimate for emergency protection of a fracture risk, needs at least three to four sessions, spread over several days to grout, only by doing this can the efficiency be improved."

A talent, must be reused!

Han Yu weighed his options, stood up and said, "Comrade Du Yuan, from now on, you are the team leader of our emergency assault team's grouting team! I will get you a self-propelled ship, a powered ship. Provide you with an experienced driver and a crew member, will also give you a mechanical repair personnel."

"Han Camp Commander, I am a new soldier, I can't be a team leader..."

"I say you can then you can, and you are indeed capable!"

Han Yu walked over and patted his arm, then turned around and asked, "Camp Commander Li, Staff He, what do you think?"

Being the team leader of the Hong Kong Garrison is either a project manager or an official cadre, or a technical expert, how can a little bricklayer be the team leader!

Li Shousong couldn't believe his ears, he didn't know how to answer, Staff He laughed and said, "I have no objection."

"Camp Commander Li?"

"I... I have no objection either."

"Since you have no objection either, then please when organizing loading and packing sandbags, assist Comrade Du Yuan to sift, fill, and transport the soil he needs."

"Yes!"

"Camp Commander Li, as of half an hour ago, Guang'an's dry dam and river dam have shown dozens of fractures, meaning the upcoming protection tasks of the grouting team will be heavy, the soil he needs is a priority, you must ensure its availability."

"Understood."

"Comrade Du Yuan, come, I'll take you to find comrades from the repair team. Hurry to think of a way, see how to complete the modification of the grouting pump quickly."

"Yes!"

...

Have you got it wrong, "Bricklayer" actually became a team leader!

The soldiers of the 132 regiment looked at each other, until Han Yu led Du Yuan far away, they hadn't recovered.

"Comrades, did you see, as long as you have good ideas, methods, superiors will adopt them. Hope everyone uses Du Yuan as an example, while executing the tasks assigned by superiors, use your brain, utilize each other's intelligence and talents, not just work mindlessly."

Staff He waved his arm passionately and said: "Of course, Comrade Du Yuan has his professional advantages, the good ways and ideas he can think of, we definitely can't come up with. But we can think of others, like comrades Liu Xiaojun and Xu Kejun, their suggestions earlier were also good, adopted by superiors too. Let's give a warm applause to congratulate comrades Liu Xiaojun and Xu Kejun!"
