Compared with the visible danger of a breach, the danger of only seeing the pipe outlet but not finding the leakage point is more worrying.

The large-scale piping surge at the Dongfanghong Drainage Station was not originally on the Linghai Reserve Battalion's rescue list. It was only this morning that superiors informed that the collapse of the Anzao embankment was caused by improper rescue and rescue of the piping surge. Linghai Reserve Battalion’s rescue mission list.

At 5:30 in the morning, as soon as Han Yu received the order, he asked 001 to send Yao Gong, Lao Li, a diver from the Linghai Development Zone Underwater Engineering Company, and three divers from the Navy Diving Team to come over for rescue.

I thought I would be able to find the leak soon, but it took me a long time to find it. Even Lao Li, who is experienced 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. Moreover, the number of duct openings increased from three initially discovered to eleven in just half a day!

When Yao Gong and others set out, Secretary Wang specially asked them to bring a big sign.

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

Looking at the eleven "Baotu Springs" with water constantly gushing out, and then looking back at the jingle on the big sign about rushing to protect the springs, Han Yu was anxious and embarrassed. He was so embarrassed that he wanted to find a crack in the ground to get in.

This is a major danger.

The township chief came as soon as he received the report from the militia patrolling the embankments. Vice Mayor Zhong of Shishou City came, as did the head of a certain People's Liberation Army unit who supported Shishou's flood control and rescue operations.

"Carefully check the springs at the foot of the embankment, and they are all hidden in the fields and ponds. Report the occurrence of springs in time, and fill them with pebbles for safety. The springs are moved without panic, and the cofferdams are filtered as they are. Double measures for water storage and pressure reduction, and guarding and reinforcement must be remembered prison."

After reading the propaganda slogan that Comrade Lao Wang asked Lao Chen to write, the chief turned around and asked: "Comrade Xiao Han, we have done everything you asked. Pebble filling, cofferdam filtering, water storage and pressure reduction, although it can't be cured at the beginning. At first, I could barely cure the symptoms, but now I can’t even cure the symptoms, what do you think we’ll do next?”

If the work is not done well, we rush to advertise.

It's okay now, I'm slapped in the face.

Han Yu was complaining secretly, and Vice Mayor Zhong asked eagerly: "Captain Han, how do your commandos usually rescue people in such a situation? I'm talking about the kind that ensures nothing goes wrong."

"Reporting to the two leaders, we have no good solution for this kind of piping danger that cannot be found and is developing and worsening. The only thing we can do is to repair a cofferdam behind the piping group. Even if If the gate breaks or the embankment in front collapses and breaches, the cofferdam can also be used to block the incoming flood water."

"Just like the dangerous situation when 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..."

The most troublesome thing is to rush to protect the danger of pipeline surge, especially the latest notification from the Provincial Defense Directorate and the Yangtze River Flood Control Bureau, which makes the people below dare not let go, because no one knows whether there will be "improper rush to protect" .

There are more and more wells in the pipes. What started out was clear water, but now it cannot be filtered. What comes out is all muddy water containing a lot of sediment.

The leader was so anxious that he looked back at the soldiers who were on standby and said, "What leader? Fang Zhi asked us to listen to you. Now that you are the biggest, you are the leader. Time is urgent, so give the order quickly."

Han Yu realized that the more urgent the situation, the more calm he had to be. He explained: "Two leaders, we were able to rescue the Yangliu section from danger not only because of our equipment advantage, but also because of luck. At that time, we urgently built a 60-meter perimeter. Weir, but the 60 meters is an arc length, in fact it only surrounds a 32-meter dangerous embankment.

Later, a collapse occurred, and it only collapsed 21 meters. If we are unlucky and a chain reaction occurs during the collapse, and the cofferdam collapses outside the protection range, then all our previous efforts will be in vain. "

Vice Mayor Zhong asked in a low voice: "Why don't you make it wider?"

Han Yu took a deep breath and reported: "It's not that we didn't consider it when formulating 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 consider Within 12 hours, we can repair a cofferdam of any length and height based on our existing equipment and on-site emergency construction conditions."

"What about us here?"

"There is a river beach below. If you want to build a cofferdam here, you must first build a dam in front, drain all the water in the river, and clean up all the silt on the river bed and river beach, and then you can build a cofferdam. So we say grab The methods used to protect Yangliu Section in Anggong County are not applicable here."

The leader didn't believe that there was nothing he could do to get rid of the pipes in front, and said loudly: "Add us. Comrade Xiao Han, I have two divisions nearby. If there are not enough, I can transfer more. 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: "Chief, if we rely solely on manpower, it may not be possible to build a cofferdam sufficient to block water in a month."

"Don't your commandos have mechanized equipment?"

"I can't get through, at least not for two days."

"Can't make it?"

"We have a lot of rescue missions." 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 clean up the silt on the river and river beaches. It takes longer to fall off.”

The chief stared at him and asked: "So there is no other way but to let it develop, or to watch it collapse?"

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

"Look quickly, think quickly!"

"yes!"

The dignified general is not commanding from the command post, but he comes here to cause chaos.

Han Yu's head got bigger and he climbed up the embankment in one breath. He 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. Can you tell me what to do now?"

"I'm not an expert in internal medicine. The current situation is indeed very difficult. I guess XCMG won't be able to do anything about it."

"Secretary Han, how about we go down and touch it again."

"Captain Li, you have exhausted too much physical strength, and the current is getting faster and faster. It is too dangerous to go into the water again, and you probably won't be able to find anything if you go into the water again."

Lao Li from the Linghai Development Zone Underwater Engineering Company turned around and looked at the navy divers who were sorting out their 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 bubbles, you can't see it. "

Yao Lirong took out his mobile phone and asked in a low voice: "Why don't you report it to the manager?"

"How to report?"

"I can only tell the truth. You just said that you treat surgery and I treat internal medicine, but we only treat diseases that we can treat. We really can't cure difficult and complicated diseases like this."

"Don't rush to report yet."

Han Yu looked back at the bottom of the embankment and said solemnly: "I'm not worried about smashing the sign. The problem now is that if we can't cure it, who can cure it? If we don't take measures quickly, the water will continue to carry sediment. If it surges into the embankment, the tragedy of An Zaoyuan is likely to happen again here."

Yao Lirong put down his cell phone: "How about I suggest Mayor Zhong organize the evacuation of the people below."

"We can make suggestions, but it is easy for us to say it, but it is not so easy for others to do it. Moreover, the water level is so high. If people under the embankment evacuate, should people on the embankment evacuate? Should this section of the embankment continue to be strictly guarded?"

"What should we do?"

"If I had my way, I could still be standing here!"

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

Han Yu subconsciously asked: "What kind of native method?"

Yao Lirong gritted his teeth, pointed to the river below the embankment and said, "We have more than two thousand tons of stone left. Transport all the stone and throw it in!"

More than two thousand tons of stone may seem like a lot, but in fact it is only two large ships. It is not enough to just throw it away. Unless you are lucky enough, there are rocks that can plug the leak.

Han Yu was silent for a moment and shook his head: "Our task is not just to protect this pipe surge, but the more than two thousand tons of stone will be of great use in the future. If we just pull it and throw it into the river, it will be equivalent to carpet bombing ants. And it won’t necessarily kill the ants.”

Captain Li was convinced. He raised his head and said, "Even if there are stones thrown at the leakage point, they may be washed away. The current below is very fast, and we can't stand even if we go down."

"This won't work, that won't work either. We can't just waste our time here just staring."

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

"All right."

…

The three of them took the iron boat back to 001, and the troop leader and Vice Mayor Zhong climbed up 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 can't worry about so much now, let's do business first."

"oh."

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

Yao Lirong hurriedly took the intercom and raised it to his mouth to call the communications and power support team.

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

"The gate is not facing the river, but is built at the mouth of an abandoned river. The mouth of the river is about 80 meters wide. Due to sedimentation, the gate and the mouth of the river are exposed to the water in the dry season. The river beach facing the Yangtze River has high It is so low that the water flow situation is very complicated. There are six whirlpools that can be seen with the naked eye..."

After Han Yu and other workers from Yao reported the situation, they took the intercom and said, "Comrades, this is basically the situation. The outlet of the pipe is constantly expanding, and more and more water is being brought in, and it is becoming more and more turbid. Conventional methods have solved the problem. We can’t get it down. There are hundreds of thousands of people under the embankment. The situation is urgent. Please use your brains together and think about how to get protection together!”

“Can’t we build the cofferdam?”

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

"Secretary Han, conventional methods are not working, we can't find the leak, and we can't repair the cofferdam. Even you can't do anything. What can we do?"

"Yes, Secretary Han, we really can't let local leaders organize people to evacuate."

…

Listening to the officers and soldiers' replies, Han Yu realized that he was in a bit of a quandary.

Just when I was thinking that the doctor would probably be blinded here, the voice of the bricklayer suddenly came from the radio: "Secretary Han, since there is no good way, then let's treat the dead horse as a live doctor."

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

"Drill more holes and drill deeper. The outlet of the pipe is at the foot of the embankment, so we can definitely drill into the seepage layer."

"Xiao Du, you mean grouting?"

"Add more cement to the slurry, increase the pressure of the grouting pump, and pour it directly into it. Maybe it can be blocked."

This is a piping, not a crack. Even if you are lucky enough to get 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, we can only treat a dead horse as a living horse doctor.

Han Yu weighed it up and agreed: "Okay, come here quickly."

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

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

Regardless of whether grouting and rushing to protect it can work, it is at least better than doing nothing. Han Yu paused and then said: "And there are many army officers and soldiers on and under the embankment. I will ask them to dig holes, dig more, dig deeper, etc." You can go down and drill holes when you arrive.”

"Secretary Han, we are assisting in the rescue operation."

"Don't worry about it over there. I'll ask the person on duty to arrange for someone to take over for you. Come here quickly and move quickly."
