Riverside Police.

At 24:[-], Han Yu was woken up by Yang Jianbo.

Although I was still very sleepy, my eyes hurt from sleepiness, but the order came and I couldn't sleep anymore.

"Secretary Han, wash your face. Here are chicken feet with pickled peppers. Mr. Zhang bought them specially for you and Mr. Hao. Eat them to refresh yourself."

"Oh, thank you."

Han Yu didn't care about eating chicken feet, washed his face and walked out of the tent. He suddenly found that the camp was empty, except for the tent he slept in just now, and the other tents were gone.

The head driver drove back the excavator from Luqiao Company, and with the assistance of the assistant driver, he replaced the excavator with the extended arm brought from his hometown.

The main arm is used during normal operations, and the 22-meter extended arm will only be replaced when demolishing buildings, digging rivers, pit foundations, deep wells or dredging.

This extended arm is not from the original factory, but produced by a small Japanese company that specializes in refitting excavators. Brother Hao asked the manager of Linghai Foreign Economic and Technical Cooperation Company to go to Japan to customize this extended arm the year before last.

The arm is longer and the bucket is smaller. Naturally, it is impossible to dig as much soil as with the main arm.

Han Yu raised the walkie-talkie and asked, "Mr. Hao, Mr. Hao, I, Han Yu, what is the mission? I need to change the long arm."

"I'll go over right away, I'll go over and tell you."

"Ok."

Han Yu put down the walkie-talkie, thought about it and asked, "Instructor, where is Mayor Shen?"

Yang Jianbo hurriedly said: "Mayor Shen has gone to Jingzhou City to defend the finger, and Deputy Mayor Xu invited him to go there. The leader of the Jingzhou defense finger may consider that although we are now an emergency rescue force in the Jingzhou section, we are a reserve force and want to give We issued an order to pass through the 105th Division of the 404th Army, a large circle would easily delay the fighter plane, and we couldn’t always bother the head of the military region like yesterday, so we invited Mayor Shen to join the Defense Command with the consent of the superior.”

"Mayor Shen joined the Jingzhou Defense Finger?"

"Well, I left with Vice Minister Li two hours ago. I visited you before I left and saw that you were sleeping soundly, so I didn't wake you up."

"What about the rest?"

"The personnel and small equipment that can be loaded have been loaded on the ship. The first batch of personnel and equipment have crossed the river and are being transferred to the shore. We are the last batch."

Yang Jianbo turned around and pointed to the empty parking lot not far away, and added: "The leaders of Jingzhou City may realize that it is inconvenient to transfer large equipment on shore, so they decided not to trouble the eight large flatbed trucks of the Port Authority. Three hours ago, Shen City Chang Rang’s car from the Port Authority went back first, and Director Liu from the Changhang Sub-bureau also went back. The main reason was that the eight large vehicles did not have license plates, and if they did not go together, they would easily be stopped by the traffic police along the way.”

How many pontoon bridge troops can there be on the North Lake?

Jingzhou City Defense Command can ask the pontoon bridge troops to support once. It is impossible to ask the pontoon bridge troops to do other things and build roads and bridges for the Linghai Reserve Battalion, and it takes time to build roads and bridges. It is far from using various ships on the water. It is convenient and quick to maneuver.

Thinking of so many people and equipment being loaded across the river, Han Yu felt very uneasy, and asked nervously, "Who is in command of the fleet?"

"Director Gu of the Port Authority, he arrived just after you fell asleep. Ge Ju and I wanted you to sleep longer, so we didn't tell you."

"With Director Gu around, I feel relieved."

"Secretary Zheng and County Magistrate Li from Lingjiang also came here to send us silk banners and help us sign and seal the project materials. It is reasonable to take a group photo, but the light is not good in the middle of the night, so the comrades in the main class After a while, they were all outside to assist in emergency rescue, and the comrades in the deputy class wanted to hurry up and sleep for a while, so Mayor Shen didn't let us call."

The emergency rescue of the Linghai Reserve Battalion is divided into two shifts, the main and the deputy. Each shift works for five hours and then rotates.

Han Yu was about to ask Dongdong if he had boarded the boat when Hao Qiusheng ran over from the embankment.

"Secretary Han, the Jingzhou Fangzhi asked us to go to Angong County. The foot of a section of the embankment was emptied by the flood, and there were many pipes on the inside of the embankment. The dangerous embankment is about 25 meters long, and it may happen at any time. Collapse."

"Have you found any leaks in the piping?"

"No, there are no blisters on the river surface. Fangzhi has already requested assistance from the Naval Diving Academy. The navy divers should arrive by tomorrow at the latest. No, they should arrive before [-] o'clock this morning."

"Have rescue measures been taken for the seepage points inside the embankment?"

"He's being rescued."

Piping refers to the phenomenon that soil fine particles form pores along the skeleton particles under the action of seepage, and the soil fine particles are washed away due to the increase of water flow rate in the soil pores, also known as sand drum water.

The diameter of the gushing water ranges from a few centimeters to a few meters, and a raised sand ring will be formed around the pores.

If the correct method is not adopted in time to rescue, the dangerous situation will continue to worsen, and a large amount of water gushing over the sand will cause the foundation soil skeleton of the levee to be destroyed, the tunnel will expand, the foundation soil will be emptied, causing subsidence, and causing the embankment to burst!

But now it is not only the piping that needs to be rescued, the foot of the embankment on the water side of the levee has also been swept away by the flood, which means that even if there is no danger of piping, the levee may collapse and burst at any time!

It may seem that there is no gate wall, the gate is cracked, and the inside of the gate is full of irregular "fountains" at the Laomiao gate, but in fact it is far more dangerous than the Laomiao gate that has become a part of the Yangtze River embankment.

After all, the gate of Laomiao gate is poured with reinforced concrete. Although the gate wall and gate plate are cracked, all the steel bars inside are not broken. The overall structure is relatively stable and has a certain strength.

Looking at the No. 1 excavator that was being replaced with a longer arm, Han Yu realized how "Brother Hao" was going to rescue him, and asked: "Find the leak first, then find a way to plug the leak, and then throw it on the river." Stones, use an excavator to push the stones into the foot of the embankment that has been emptied, to see if they can support the embankment first?"

"Equipment cannot go on the embankment, it can only work on water."

"Is there enough stone?"

"Command says yes, but it will take time."

"When will it arrive?"

"do not know."

"Where's the woven bag?"

"There are woven bags, and they are being sent there. The county promises to send [-] bags there before dawn, and the city's defense department allocated [-] bags."

The biggest problem here is the serious lack of emergency supplies!
Hao Qiusheng took a deep breath, and continued: "They really don't have any piles. Fortunately, there are more than 500 piles left when they rushed to protect the gate. Otherwise, they would have to cut down trees and pull up telephone poles."

Just as I was talking, the extension arm of the No. 1 excavator was replaced.

The main arm cannot be thrown here. Excavator No. 1 used the extended arm just replaced, and with the assistance of excavator No. 2, hoisted the main arm that had just been replaced, and slowly went to the river embankment under the command of the safety officer. move.

At 27:001 in the middle of the night, the transfer personnel and the equipment steam ferry came back under the escort of [-] and the supervision boat of Jingzhou Harbor Supervision Bureau, and slowly leaned up to the embankment and lowered the deck.

As soon as the deck rested on the river embankment, several crew members ran up to tie the cables.

The two small tugboats following behind were also under the command of Gu Pengfei, the director of the floating crane wharf of the Port Authority and the sub-leader of the water navigation and anchoring safety unit of the Linghai Reserve Battalion. .

The arm is a key part of the excavator, and it must be hoisted on the ship with care, care and care.

The No. 2 loader that came back with the steam ferry came to assist. More than 10 people worked hard for nearly 1 minutes before safely transporting the main arm of the No. [-] excavator onto the steam ferry.

The danger in the embankment section of Laomiao gate has long been ruled out. This is no longer the command branch of the Lingjiang County Defense Command on the main embankment of the Yangtze River. Deputy county magistrate Wang has long since left, leaving only a few cadres and a dozen backbones The militiamen patrolled the embankment in this area.

Seeing that the last batch of personnel and equipment of the Linghai reinforcements was about to leave, they rushed over from the east and west to see them off.

"Captain Han, thank you. I don't have anything with me. I only have two packs of cigarettes on me. Don't feel bad about it if you show some kindness."

"Commander Han, Commander Hao, I'm Wang Shuwen, the deputy mayor of Laomiao Township. After the flood is over and you're not busy, you are welcome to visit our Laomiao!"

The basic militia guarding the embankment are all nearby villagers, and they have to bring their own food from home.

A militiaman brought a few boiled eggs from home before going up the embankment. Seeing that Han Yu and the others were about to leave, he quickly took them out and stuffed them into Han Yu's hands.

The deputy mayor smokes red plums, which are not very good cigarettes.

He didn't know how long he was going to stay on the embankment, so he gave Hao Qiusheng the only two packs of red plums left.

Han Yu and Hao Qiusheng knew very well that they would be unhappy if they didn't accept them, so they could only accept them with tears in their eyes and waved goodbye to them.

……

At the same time, the Yangliu village section of the Yangtze River embankment in Angong County suddenly became brightly lit.

The power generation room of the communication and power support team has been transferred from the shore to a cargo ship that transported stones to Laomiao Gate last night.

In order to hoist the power generation room converted from the container onto the ship, the Linghai Reserve Battalion exhausted their efforts.

It took more than an hour of night flight to arrive here, and with the help of party members, cadres and militiamen in Angong County, everyone transported the equipment that could be transported ashore.

The "landing site" is about one kilometer away from the embankment where the piping occurred. The reason why we choose to land here is because of safety considerations. If a dangerous embankment collapses and breaches, people and equipment will not be washed away by the flood.

The second is that the levee here is relatively wide and strong, ships can berth, and construction machinery such as excavators and loaders can disembark from here.

Han Yu and Hao Qiusheng were behind, and it would take an hour and a half at the fastest to arrive.

Zou Xiangyu, the project manager of the Road and Bridge Company, became the commander-in-chief of the front line without hesitation, and Xu Gong continued to communicate with the leaders of Angong County who were directing the emergency rescue on the river embankment as the flood control expert of the Yangtze River Defense Command.

Sun Youyi, the chief engineer of the Road and Bridge Corporation, led several team leaders to investigate the dangerous situation on the spot, and seized the time to study and formulate a more specific emergency construction plan.

Yao Lirong didn't care about making engineering materials, and according to the plan, the personnel who did not have emergency construction tasks were temporarily organized into six embankment inspection teams to conduct a carpet-like investigation within a radius of one kilometer of the "landing site" to see if there were any water leaks here. Even manage dangerous situations to ensure the safety of the "landing field" and the new camp area to be built.

"Xugong Xugong, I, Zou Xiangyu, where is the soil collection point? I have to hurry up and level the site, and when the excavator arrives, I will take soil and fill it with sandbags. How can we rescue without sandbags!"

"Received, County Magistrate Huang will arrange for someone to take you there."

"Xugong, please ask the county leaders to arrange three more guides for us. Mr. Zhang and Secretary Qiu are not familiar with this place, and they need two guides to take them to purchase logistics supplies. Ge Ju will go to the regiment headquarters with Staff Officer Dai after dawn, and they also need guides .”

"Got it, arrange it immediately."

"Wait, isn't there a woven bag in the county? Tell them to send the woven bag to the soil collection point as soon as possible!"

"Manager Zou, the danger here was just discovered in the middle of the night. In order to resist the flood peak, we used up all the available woven bags."

"Didn't the city guard say it was there when they gave us the order?"

"Yes, people are trying to raise it. It takes time to raise it, and it takes time to transport it here!"

"Let them hurry up."

"I know."

The Jingjiang embankment on the other side of the river is more important than the dry embankment here, because behind the embankment is the Jianghan Plain.

Although the dike here is not as "important" as the other side, the severity of the disaster on this side is far greater than that on the other side.

There are already several dikes and embankments abandoned here!
The homes of tens of thousands of people were flooded. Those who had relatives went to relatives, and those who could not find relatives were either placed in schools or warehouses in nearby towns and towns, but more victims could only live in tents or sheds propped on the embankment. .

In the face of natural disasters, the power of individuals is limited, and the power of local governments is also limited.

The county leaders had done everything they could. XCMG couldn't bear to urge the county leaders any more, and told the county leaders about the soil collection points and guides, and went down the embankment with a flashlight to monitor the infiltration of pipes.

For emergency rescue in dangerous piping situations, the best way is to intercept and back-guid, conduct pressure at the same time, reduce seepage pressure, prevent seepage from bringing out sediment, directly blocking seepage is not only useless but dangerous.

Led by an engineer from the County Water Conservancy Bureau, he went to a rice field about 30 meters away from the embankment and found that the rescue measures in the county were quite appropriate.

The two-level village cadres organized the nearby villagers to carry the sandbags from the leizi embankment down from the levee, and built a circle around the six water holes to build six surrounding wells of different sizes, and the bottom of the well wall and the ground were also tightly pressed.

The well was also covered with straw as a filter material in accordance with the requirements of three-layer reverse filtration, and several drainage pipes were installed at the well head to guide away the seeping water to prevent the overflow from collapsing the well wall.

"XCMG, there is only so much we can do. We also want to plug the leak as soon as possible, but now we don't know where the leak is! Before you came, there was no electricity on the embankment, so you could only use a few flashlights for lighting. The situation is unclear.”

The old engineer of the County Water Conservancy Bureau has been "fighting fires" since the end of June. He has not returned home, bathed, changed his clothes, or even brushed his teeth for more than ten days.

With disheveled hair and dirty body, at first glance he doesn't look like an engineer at all, more like a beggar.

Knowing his bad breath, he was afraid of tainting XCMG, covered his bearded mouth, and said solemnly: "Hong Feng is gone, but the water level is still high, the river is so deep and the flow is so fast, if we just arrange people to go down to touch it, who can guarantee it?" Can those who go down come up?"

If you don't arrange people to go down and touch it, how will you know where the leak is?

001 has an underwater surveying and mapping system, but it can only survey and map the condition of the riverbed and the embankment below the water surface, and no leaks can be detected.

Xu Gong was about to say that the Municipal Defense Bureau had asked the superiors to arrange for naval divers to come to assist, but the old engineer choked up and said: "Our An Gong has lost too much, and our An Gong can no longer die."

Xu Gong was stunned for a moment, not knowing what to say next.
