Chapter 670 Dead Horses as Living Horse Doctors
Compared with the visible danger of a breach, the danger of only seeing the spout but not the leak is more worrying.

The large-scale piping hazard at the Dongfanghong electric platoon station was not originally on the rescue list of the Linghai Reserve Battalion. It was reported by the superiors this morning that the collapse of the embankment was caused by improper rescue of the piping hazard. List of rescue tasks for the Linghai Reserve Battalion.

At 5:001 in the morning, as soon as Han Yu received the order, he asked [-] to send Yaogong, Lao Li, a diver from the Linghai Development Zone Underwater Engineering Company, and three divers from the Navy Diving Team to rescue him.

I thought the leak would be found soon, but after searching for a long time, even Lao Li, who has rich experience in underwater construction, went into the water, but he couldn't find the leak!

The pipe outlet is 21 meters away from the electric drainage station, which can be said to be at the foot of the embankment at the junction of the electric drainage station and the embankment.And the number of pipe outlets has grown from three to eleven in just half a day!
When Yao Gong and the others set off, Secretary Wang specially asked them to bring a big sign.

As soon as they arrived here in the morning, they hurriedly inserted the big sign.

Looking at the eleven "Baotu Springs" gushing out, and looking back at the jingle on the big sign about emergency rescue, Han Yu was anxious and embarrassed, so embarrassed that he wanted to find a crack in the ground.

This is a serious danger.

The mayor of the town came as soon as he received the report from the militia patrolling the embankment to check for danger. The deputy mayor of Shishou City, Zhong, also came, and the head of a certain PLA unit who supported Shishou in fighting the flood also came.

"Carefully inspect the springs at the foot of the embankment, and they are hidden in the Tianzhong pond. When there are springs, report them in time, and fill them with pebbles to ensure safety. The transfer of the springs is not in a hurry, and the cofferdams are filtered as they are. The double measures of water storage and decompression, guards and reinforcements must be remembered prison."

After reading the propaganda slogan that Comrade Wang asked Lao Chen to write, the chief turned around and asked: "Comrade Xiao Han, we have done everything you asked. Although the cobblestone filling, cofferdam reverse filtration, and water storage and decompression cannot be cured at the beginning. Originally, it could barely treat the symptoms, but now it can’t even cure the symptoms, what do you think is going to be done next?”

If the job is not done well, I am in a hurry to advertise.

Well now, you've been slapped in the face.

When Han Yu was complaining secretly, Deputy Mayor Zhong asked eagerly: "Captain Han, in such a situation, how do your commandos usually rescue and protect them? I'm talking about the one that ensures everything is safe."

"Reporting to the two leaders, we can't find any leaks like this, and we have no good way to deal with the ever-growing and worsening piping danger. The only thing we can do is rush to repair a cofferdam behind the piping group. If the sluice gate breaks or the levee in front collapses and breaches, the cofferdam can also be used to block the incoming flood.”

"Just like the dangerous situation where you rushed to protect the Yangliu section of Angong County?"

"Yes."

As soon as Han Yu finished speaking, the head of the army said: "Then what are you waiting for, let's organize and implement it."

Han Yu said with a bitter face: "Chief..."

Rescuing and protecting the dangerous situation of the pipeline is the most troublesome thing, especially the latest bulletin of the Provincial Defense Command and the Yangtze River Defense Command, so that the people below dare not let go, because no one knows whether there will be "improper rescue and protection" .

There are more and more outlets in the pipes. At the beginning, what gushes out is clear water, but now it cannot be filtered, and what gushes out is muddy water with a lot of sediment.

The chief was very anxious, looked back at the soldiers who were waiting for orders, and said: "What chief, let us listen to you, you are the biggest now, and you are the chief. Time is urgent, so hurry up and give orders."

Han Yu realized that the more urgent the situation, the more calm he should be, and he explained: "Both leaders, Yangliu Duan was able to rescue the dangerous situation not only because of our superior equipment, but also because of luck. At that time, we rushed to build a 60-meter cofferdam However, the 60 meters is the arc length, and in fact only a 32-meter dike is surrounded.

Later, a collapse occurred, and it only collapsed 21 meters.If you are unlucky and a chain reaction occurs during the collapse, and the protection range of the cofferdam collapses, then everything we have done before will be in vain. "

Deputy Mayor Zhong asked in a low voice, "Why don't you make the circle longer?"

Han Yu took a deep breath and reported: "It's not that we didn't think about it when we formulated the rescue plan. But the situation was urgent and we didn't have much time left. We had to consider our earthwork construction capabilities, that is, we had to take into account Within [-] hours, with the existing equipment and on-site rescue construction conditions, we can repair the cofferdam of any length and height."

"Then where are we?"

"There is a river beach below. If you want to rush to build a cofferdam here, you must first go to the front to build a dam, drain all the water in the river, and clean up all the silt on the river bed and river beach, and then build the cofferdam. So the rush The methods used to protect Yangliu Section in Angong County cannot be applied here."

The chief didn't believe that there was no way to use the spouts in front, and said loudly: "Add us. Comrade Xiaohan, I have two divisions nearby. If there are not enough, I can transfer them. I will give you as many troops as you want. I can take the lead myself!"

Han Yu could understand the chief's mood, and said helplessly, "Sir, if you rely on manpower alone, you may not be able to build a cofferdam that is enough to block the water in a month."

"Don't your commandos have mechanized equipment?"

"I can't make it through, at least within two days."

"Can't come?"

"We have a lot of rescue tasks." Han Yu thought about it and pointed to the river in front of him and said, "Even if we can come here, it will take at least a day and a night to drain the water in this river, and to clean up the silt on the river and the river beach." It takes longer to drop."

The chief stared at him and asked: "So there's no way, we can only let it develop, and we can only watch it collapse?"

"Chief, don't worry, let me take a look and think again."

"Look quickly, think quickly!"

"Yes!"

The dignified general, who is not commanding in the command post, actually came here to add to the chaos.

Han Yu's head grew big, and he climbed up the embankment in one breath, and asked in a low voice: "Yao Gong, I am a surgeon, and I don't know how to treat this kind of internal disease. You are an internal medicine expert, what do you do now?"

"What kind of internal medicine expert am I? The current situation is really difficult. I guess there is no good way for XCMG to come here."

"Secretary Han, why don't we go down and touch it again."

"Captain Li, you've exhausted your energy too much, and the current is getting faster and faster. It's too dangerous to go into the water again, and you won't be able to feel anything if you go into the water again."

Lao Li from the underwater engineering company of Linghai Development Zone turned around and looked at the naval divers who were sorting out equipment on the 001 deck, clenched his fists and said, "The main reason is that the water flow here is too complicated, even if it is bubbling, you can't tell it. "

Yao Lirong took out his mobile phone and asked in a low voice, "Why don't you report to Xi Gong?"

"How to report?"

"I can only tell you the truth. You just said that you are in surgery and I am in internal medicine. But we only treat diseases that we can treat. We really can't cure such intractable diseases."

"Don't rush to report."

Han Yu looked back at the embankment and said solemnly: "I'm not worried about smashing the signboard. The problem now is that we can't cure it. Who can cure it? If we don't take measures quickly, we will let the water carry the sediment continuously. If it rushes into the embankment, the tragedy of Anzuo embankment is likely to repeat itself here."

Yao Lirong put down his mobile phone: "Will you suggest that Mayor Zhong organize the evacuation of the people below?"

"We can make suggestions, but it's easy for us to say, but it's not so easy for others to do. Besides, the water level is so high, people under the dike should evacuate, should people on the dike evacuate? Should we continue to guard this section of the dike?"

"What should I do?"

"If I have a way, I can still stand here!"

"Secretary Han, if it doesn't work, we can use local methods."

Han Yu subconsciously asked, "What local method?"

Yao Lirong gritted his teeth, pointed to the river below the embankment and said, "We still have more than 2000 tons of stones left, so transport all the stones and throw them down!"

More than 2000 tons of stone materials seem to be a lot, but in fact they are only two large ships, so it is not worthwhile to just throw them down like this.Unless you are lucky enough, there are rocks that can plug the leak.

Han Yu was silent for a moment, then shook his head: "Our task is not only to rescue this piping, but the 2000 tons of rocks will be of great use in the future. If we just pull them over and throw them into the river, it is equivalent to carpet bombing ants, and It doesn’t necessarily kill the ants.”

Captain Li thought it was true, raised his head and said: "Even if there are stones thrown on the leak point, they may be washed away. The current below is very fast, and we will not be able to stand when we go down."

"This doesn't work, that doesn't work either, we can't just sit here and stare blankly."

"Get on the boat first, and hold a meeting with Zhuge Liang."

"Ok."

……

The three returned to 001 by iron boat, and the head of the army and Deputy Mayor Zhong climbed onto the embankment.

Captain Li had never seen such a big official before, and asked anxiously: "Secretary Han, is that general worried about us running away?"

"I don't care about so much now, let's do business first."

"Oh."

"Yao Gong, you know the situation best, you tell the big guy." Han Yu walked into the command cabin, turned on the high-frequency radio, and handed over the communicator.

Yao Lirong hastily took the communicator, held it up to his mouth, and called the communication and power supply team.

When Yan Gong heard the call, he immediately connected the signal of the high-frequency radio station to the repeater of the walkie-talkie, so that as many officers and soldiers as possible could hear it.

"The gate is not directly facing the river, but is built at the mouth of an abandoned Tongjiang River. The mouth of the river is about 80 meters wide. Due to sedimentation, the gate and the mouth of the river will be exposed to the water in the dry season. The river beach on the side of the Yangtze River is high. Low, resulting in very complicated water flow, there are six eddies that can be seen with the naked eye..."

Han Yu waited for Mr. Yao to report the situation, and took over the intercom: "Comrades, this is basically the situation. The mouth of the pipe is constantly expanding, and the water brought up is getting more and more turbid. Conventional methods have already There are 10,000+ people under the embankment, and the situation is urgent, please use your brains and think about how to rescue them together!"

"Can't repair the cofferdam?"

"The site does not have the construction conditions to repair the cofferdam, and it is impossible for us to bring all the equipment to repair the cofferdam now."

"Secretary Han, the conventional method doesn't work, we can't find any leaks, and we can't repair the cofferdam. Even you can't do anything about it. What can we do?"

"Yes, Secretary Han, it is really impossible to let the local leaders organize the masses to evacuate."

……

Listening to the officers and soldiers' quick-talking replies, Han Yu realized that it was a bit embarrassing for the big guy.

Just thinking that Mr. Xi would probably be blinded here, the voice of the little bricklayer suddenly came from the radio: "Secretary Han, since there is no other way, let the dead horse be a living horse doctor."

"Tell me, how can a dead horse be a living horse doctor?"

"Drill more holes and drill deeper. The pipe outlet is at the foot of the embankment, and it will definitely reach the aquifer."

"Xiao Du, you mean grouting?"

"Add more cement to the grout, increase the pressure of the grout pump, and pour it directly, maybe it can be blocked."

This is a pipe, not a crack. Even if you are lucky enough to pour the slurry in, it will be brought out by the water.

But the current situation is that there is really no better way. In the words of the little bricklayer, he can only be a dead horse as a living horse doctor.

After weighing it up, Han Yu agreed, "Okay, come here quickly."

Du Yuan didn't expect Han Yu to actually adopt his suggestion, and hurriedly said: "Secretary Han, our drill bit is not long enough to drill that deep!"

"It's next to the gate, and the embankment is very wide, at least seven or eight meters."

No matter whether the grouting and rescue work is effective or not, at least it is better than being helpless. Han Yu paused, and then said: "Besides, there are many army officers and soldiers on the embankment and below the embankment. When you arrive, you can drill down into the pit."

"Secretary Han, we are assisting in emergency rescue."

"Don't worry about it over there. I'll ask the attendant on duty to arrange someone to replace you. Come here quickly and act quickly."
