There is a shortage of emergency materials in Jingzhou, especially sand and gravel to seal breaches and protect slopes. This is indeed a headache.

"Everyone, Secretary Han is right. It is unrealistic to bring materials there. It seems that we can only rely on sandbags."

"Mr. Hao, woven bags and straw bags are good to carry. They are not heavy and do not take up space when stacked, but they are troublesome to fill. It takes at least 30,000 to 40,000 square meters of soil to seal a breach. We don't have to do anything else. It’s too busy just filling sandbags.”

"Not only are we too busy, but we have to race against time to seal the breach. How can we have so much time to fill sandbags!"

Sun Youyi paused, then continued: "Filling sandbags requires sand and gravel, digging, shoveling one by one, shoveling into the woven bag, sewing it, and after sewing it, it needs to be tied with lead wire (iron wire). If you want to put it on It is not easy to tie the ton-weight sandbags firmly, and the lead wire cage tied with lead wire must not be hoisted and can only be thrown with a loader."

Lu Wei from the Waterway Engineering Bureau reminded: "Worker Sun, we don't necessarily have to tie it with lead wire. Didn't Secretary Han say that we can weld the steel cage?"

"The cost of the steel cage is too high, and it takes time to process the cage. We don't have many steel workers in the whole camp!"

"That's true."

"Secretary Han, why don't you ask Huang Chu if the materials can be purchased from Jingjiang?"

"There's no need to ask anymore. He may not even know the situation in Jingzhou as we do. I called Xi Gong and Yao Gong on the way back. It doesn't matter what they want there now. You may not believe it, Sandbags are needed for Leizi Embankment, but the local government does not have woven bags and straw bags, so people can only bring them from home.”

Han Yu took a deep breath, looked around at the crowd and said: "If you want to drive piles without piles of wood, you should first pull out the nearby telephone poles. When the telephone poles are used up, cut down the trees of nearby villagers' houses. Without the sand and gravel needed to protect the embankment, we can only demolish the houses of ordinary people." . It is said that the cadres there have another job, which is to collect flood prevention fees from door to door."

Mr. Hao couldn't believe this was true, and asked in surprise: "There is no flood prevention funds over there?"

"Beihu's economic development is not as good as ours. Xi Gong and Xugong said that the salaries of many local cadres and teachers cannot be paid on time. There is no flood prevention funds at the county and township levels, let alone any flood prevention material reserves. The state The flood control funds allocated by the province and the province seem to be a lot, but since more places are affected by the disaster, it can be said to be a drop in the bucket."

"No wonder they mobilize donations every day."

"Let's not talk about this anymore, let's think about how to deal with emergency materials."

Speaking of which, they all have diplomas and are engineers.

Don’t you just think that tying sandbags with lead wire is troublesome and not strong?

Zhang Erxiao raised his head and said: "There is no need to use lead wire to tie sandbags, and there is no need to find a steel barman to make a steel cage. We can purchase more iron straps, and then purchase two pneumatic iron strapping machines to tie them with other people's factories. Just like the wooden box that contains the equipment, first use iron belts to hoop the sandbags, then clamp and tighten them with a baler, and then clamp the iron sheets at the interface. It is automatic, fast and very strong!"

Doing engineering is different from running a factory.

On the construction site every day, it is difficult to see how the products produced in the factory are packaged. Naturally, I would not have thought of such a thing as an iron belt baler.

Lu Gong was stunned for a moment and looked at Han Yu subconsciously.

Han Yu suddenly reacted and murmured: "I have seen many wooden boxes packed with iron belts, but I have never seen the process of tying wooden boxes with iron belts. Mr. Zhang, you have made another great contribution."

"What kind of work is this? We have several factories with iron belt balers in our development zone. Whether the baling is fast and the knots are strong, you will know if you go and take a look."

"Is it available in our development zone?"

"As long as there are factories that produce machinery and equipment, there are also small factories that produce industrial sewing machines. There are also some factories that produce equipment that is not heavy and packed in cartons. People don't use iron belt balers, but use plastic belt balers for packaging. The interface It's not clamped, it's attached with some kind of hot melt glue, the kind of white plastic tape used to package TV sets."

"I'll know it as soon as you say it. It's a good idea to tie the sandbags with iron belts. Go next door and call them and ask where they bought the iron belts and iron belt balers they use."

"Okay, I'll go out and call and ask."

"Everyone, this leaves only the issue of filling. Let's think about how we can improve the efficiency of filling sandbags."

Zhang Erxiao opened up Zhang Jiangkun's thinking.

He immediately raised his hand and said with a smile: "It's easy to improve the filling efficiency. Use thicker steel to weld a hopper, install a screw conveyor inside, twist and push the sand forward, and put it under the head of the screw conveyor. Install a splice port, put the woven bag on top of the splice port, and you can fill a bag in two seconds at most.”

This principle is not complicated!

Han Yu was amused and said by analogy: "Keep track of the size and install a conveyor belt under the material receiving opening. When the bag is full, it will be sent to the side to be sewn, and the bag mouth will be put on the other side and the filling will begin again."

Zhang Jiangkun nodded with a smile and added: "It is too slow to use the small sewing machine in Zhang Er's small factory to sew. You can buy a sewing machine like the one used in cement plants and fertilizer plants and install it in the filling machine." On the edge of the mouth, the operator can hold the bag mouth over and sew it directly.”

It's really a specialization in the art.

I can only do engineering, but others know mechanical technology.

Hao Qiusheng asked with a smile: "Manager Zhang, according to you, it's almost like an assembly line?"

"It's a filling line. All large companies that use woven bags to fill products have such equipment."

"Secretary Han, can you buy one?"

"This is special equipment. The one that fills flour is different from the one that fills fertilizer. It is unrealistic to use it to fill sand and gravel. The design is not difficult, but it takes time for manufacturers to produce it."

As soon as Han Yu finished speaking, Zhang Jiangkun raised his hand again: "We can make one ourselves. It's very simple. It mainly consists of three parts: transportation, vibration and seam. Composite rubber spring, rubber spring, chain, conveyor belt, spiral Conveyors, belt conveyors, vibration motors, and reducers can all be purchased.”

It is really difficult to make common machinery, but it is not difficult for those who know how to do it.

Han Yu has full confidence in his brother-in-law, because he is not just a mechanic. When the Port Authority followed suit and produced cars, his brother-in-law was the technical backbone of the Port Authority's automobile manufacturing plant!

However, the main purpose was to purchase chassis and engines and assemble them. The Port Authority Automobile Manufacturing Plant only made shells, but they did make a few minibuses, which made a sensation all over Binjiang. It was just because the quality was not very good that it was always easy to run. Breakdowns occurred, production costs became a bit high, and it eventually closed.

In fact, it was not just the Binjiang Port Authority that produced cars. The seven districts and counties in Binjiang once had their own car manufacturing plants. Later, like the Port Authority's car manufacturing plants, they all went bankrupt for one reason or another.

It is easier to purchase steel materials, mechanical equipment and spare parts to build a semi-automatic sand and gravel filling and seaming machine than to piece together a car.

Han Yu said with a smile: "Brother-in-law, I leave this task to you. Hurry up and place the order, and go shopping when the order is given!"

Hao Qiusheng asked curiously: "Is it too late?"

Before Han Yu could speak, Zhang Jiangkun said confidently: "We have so many people and machine processing equipment, so four or five days are enough. Besides, we just need to build one that can be used, and it doesn't have to look good."

"But if the order really comes, we can't wait four or five days!"

"It can be done on the ship. When the fleet arrives in Jingjiang, the filling machine will definitely be ready."

In the camp, not only my brother-in-law and his few mechanics, but also the mechanics and sailors on floating cranes, steam ferries and tugboats almost all know how to do machining.

Han Yu believed that it could be done with the existing technical capabilities, and said by analogy: "Brother-in-law, I don't know how much the iron belt baler in Zhang Er's novel weighs. Let him ask later. If it is heavier, do you still need it?" Solve the problem of efficiency of tying sandbags with iron belts.”

"If it's heavier, weld a bracket, install a slide rail or a movable arm on the bracket, hang the baler on it, and pull it over when it needs to be tied and packed, so it doesn't have to be as strenuous as lifting it."

"That's what I think. In short, you have to use your brains. Everything revolves around efficiency. Do it as quickly as possible!"

"knew."

"Manager Zhang, if there is a filling and sewing machine, how long does it take to fill and sew a sandbag?"

Zhang Jiangkun thought for a while and said with a smile: "Three to four seconds."

Lu Gong picked up the calculator and said while calculating: "If we fill one bag in four seconds, we can fill and pack 900 bags in one hour. Each bag of sand and soil is about 80 kilograms, which means that it can be filled in one hour." Thirty-six tons of sand can tie up thirty-six iron belt cages.

If the personnel work in three shifts and fill and tie non-stop 24 hours a day, more than 800 iron belt sand and soil cages weighing about one ton can be processed in a day and night. Calculated at 0.4 cubic meters per ton of sand, it is equivalent to processing 345 cubic meters of stone a day and a night. "

After hearing Lu Gong's calculation, Mr. Hao was no longer as happy as before. He frowned and said, "More than three hundred square meters is enough for what you can do. It's only equivalent to a shipload of stone."

"Mr. Hao, Gong Lu, I can think of a way to make two or three discharge ports to increase the filling efficiency by two to three times."

"Increase it to 24 hours to fill the equivalent of 1,500 tons of stone?"

"Um."

"Although it won't solve the big problem, having these 1,500 tons is definitely better than nothing."

"Everyone, I still have a question. Where does the sand and soil come from?" Han Yu said, holding his chin: "If you want to fill it into the hopper, you must first have materials."

Hao Qiusheng said thoughtfully: "When we arrive in Jingzhou, we will first find a place where we can get soil, use two excavators to dig more soil and pile it there, and dig it as long as we have time. But we can use manpower to dig out the soil one by one with spades. It is unrealistic to shovel sand and soil into the hopper, and our loader needs emergency construction. Secretary Han, can you think of a way to recruit another loader."

Vice Mayor Qin just said that if there are not enough vehicles and construction machinery, feel free to bring them, and he will contact the city leaders of Gaoru and Changzhou to help solve the problem. But this construction machinery is limited to ordinary machinery. It is unrealistic to want an excavator. After all, people may not have one themselves.

However, loaders are not particularly rare construction machinery.

Han Yu smiled and said: "No problem. Considering the transportation problems after the iron sandbag cage is tied, I think we should find another way to find a forklift."

Sun Gong said inferences: "Secretary Han, the iron belt sandbag cage cannot be thrown by the loader alone. The iron belt can only play a binding and fixing role. Should we combine it with the steel cage and use steel bars or steel wire rope hoops to hoop it? In this way, it is not only convenient for hoisting and loading, but also can be thrown using a floating crane during rescue operations.”

"Okay, you guys hurry up and think of a way to save costs and improve efficiency. I'll take a call first."

"good."

As soon as Han Yu walked out of the exhibition hall, he saw Huang Yuanchang running over from the camp. Judging from his expression, there should be good news. But this call was from the manager. He had to answer the phone first and didn't bother to ask Huang Yuanchang what was going on.

"The mat worker, I'm Han Yu."

"Xianyu, the order has come down. Liu Gong from our Yangtze River Commission Design Institute just called me and told me. He is now the flood control expert of the Yangtze River Control Center and has the best information!"

"real?"

"He even saw the order to mobilize your battalion!"

Han Yu was overjoyed and asked eagerly: "What does the order say?"

"wait."

Xi Gong picked up the phone call record he had just made and read: "Commander Zhu Weihui and Political Commissar Miao Baokun of the Jiangnan Military Region transferred to Commander Wang Shengpeng and Political Commissar Tian Fang of the 105th Army of the Guangzhou Military Region: Due to continuous heavy rains in the Yangtze River Basin, flood control in the Jingjiang section of the Yangtze River The situation is serious. At the request of the Yangtze River Defense Command, the Binjiang Flood Control and Rescue Battalion of the Jiangnan Army Reserve Division is ordered to immediately go to Angong County, Jingzhou City, Beihu Province to accept the command of the 404th Division of the 105th Army and cooperate with the 404th Division in carrying out rescue missions. W, Y Army, July 1998 June 6th.”

Han Yu thought he heard wrongly and asked in a low voice: "Just these few words?"

Xi Gong asked with a smile: "You are only a battalion-level unit, or a reserve battalion. What do you want the Chinese Y Army W to say?"

"That's true." Han Yu thought for a while and asked: "But Huang Chu from the China Changhang Aviation Bureau said that we were going to report to the Jingzhou Military Division and accept the command of the Jingzhou Military Division. Why did it change again?"

Xi Gong looked up at the excited Yao Gong and Xiao Chen who were gearing up, and explained: "I was surprised at first, but later I asked Liu Gong and found out that the superiors were worried that you would cause chaos to the Jingzhou Military Division, so they changed the command of the 404th Division to you."

"Does the 404th Division understand flood prevention and emergency rescue?"

"Don't worry, people won't let laymen command experts. I almost forgot to tell you that I was transferred to the Yangtze River Prevention Command and responsible for guiding the flood control in the Jingjiang section. On the issue of how to rescue, people respect my opinions and those of the local water conservancy department. "

Han Yu finally relaxed and was about to ask when this order would be delivered to Binjiang. Xi Gong smiled and added: "The 105th Army is an airborne army, and the 404th Division is the recruit instructor of the 105th Army. It can be seen that the superiors take great care of you. Yes, treat you as new recruits. If the logistics supply of the long-range voyage system cannot keep up, they will definitely take care of your livelihood."

"They're airborne troops!"

"Um."

"They are professionals when it comes to parachuting and fighting, and we are indeed recruits. But when it comes to flood prevention and rescue operations, we are professionals, and they are the recruits."

Thinking of the situation outside, Xi Gong stopped laughing and said solemnly: "Xianyu, the situation here is different from Jiangnan. The problem cannot be solved by controlling a few major dangers in time, nor can a few executions be blocked in time. I can sit back and relax if my mouth breaks."

Han Yu asked in a low voice: "So serious?"

The bench worker took a few deep breaths, frowned and said: "As for dangers, there are dangers everywhere here. Every section, every meter, as long as we can see it is a danger! Have you ever been a fire fighter in Changhang Binjiang Branch? The deputy captain of the detachment is still the secretary-general of the Binjiang Water Fire Fighting Association. I suggest you be mentally prepared to be a 'flood prevention and rescue fire brigade'!"
