Now Lin Yi understood that the reason was this huge stone.
It is impossible for the embankment to be strong with soil alone. It must rely on the grass growing on it to maintain the stability of the embankment.
Even though the grass on the embankment is only tens of centimeters high, their tiny rhizomes are already densely distributed in the ground. It is precisely because these rhizomes can firmly lock the soil that the embankment will not be carried away by the river water.
The biggest reason why water and soil erosion is so serious in the Loess Plateau is that the ground vegetation has been destroyed too much, and the grass roots cannot hold the soil. When the water washes away, the soil will naturally follow it.
The grass roots are so powerful that they cannot penetrate into the boulders. This means that although the soil here is thicker, the grass roots cannot connect the upper and lower parts of the dam into a whole. It is like a rootless tree, very fragile.
.
Strong on the outside and dry on the inside is the best word to describe this section of the dike. Naturally, this is also the most disadvantageous terrain.
The fire squadron is now beginning to suffer a loss. No matter how hard the sandbags are thrown, the sandbags will be squeezed out by the flood because the friction brought by the stones is too small. As for the fire fighters standing on the boulders, the reason why they stand more stable is because
The boots they wear are more suitable for flat ground.
In addition, they held hands to form a human wall, and they were already one unit, so this wall was far stronger and sturdier than the one made by sandbags.
The squadron leader also saw this problem and immediately shouted: "The next class we go to, the sandbags can't block it, so we use our bodies to block it. I don't believe it. We still can't fix this place."
But the people who were blocking the embankment couldn't hear the squadron leader's words. Their various senses had been depleted by the impact of the flood, but their bodies could feel people jumping down from below. This
They mistakenly thought that their mission was completed, so the strength to rely on willpower was gone, and they drifted downwards with the flood.
As a steady stream of people jumped into the breached embankment, a steady stream of people were swept away by the flood.
Manpower was overwhelming. When people from three classes jumped into the breach, the number of sandbags finally piled up. In more than an hour, the fire squadron once again completed the feat.
Lin Yi's side was also extremely busy. Although the rocky area was covered with young branches, the force of the flood was too great. Even with the obstruction of young branches, the impact was greatly delayed, but it was washed down.
Firefighters still suffered scratches on their limbs, and one soldier even had a gash in his leg ripped open by rocks, and blood could not stop flowing out.
But even so, the soldier who was almost fainted by the flood could not feel any pain. It was not until he was rescued by Lin Yi and sprayed with alcohol for disinfection that the soldier recovered.
But before the pain spread all over his body, Lin Yi had already bandaged him with extremely fast techniques and said: "Don't move yet. You can't do strenuous exercise because of your injury. I will arrange for you to move to a private house later."
Rest. This is an order and must be carried out."
Lin Yi usually wouldn't give orders to suppress anyone, but these soldiers' desire for disaster relief was above all else. Sometimes, without giving orders, he was afraid that he wouldn't be able to suppress them.
When the fire fighter heard this, he suddenly lost his expression, "Company Commander Lin, am I considered a deserter?"
Lin Yi was very surprised when he heard this, "You are injured like this, who dares to say that you are a deserter? I am the first one not to want to. Don't have these burdens in your heart, what you have done is enough for everyone."
You are so proud, take good care of yourself now and return to the squadron as soon as possible is the most important thing."
The fourth squad leader ran over at this time and pulled Lin Yi aside, "Captain Lin, I have just checked that these soldiers who were washed down by the flood all have varying degrees of abrasions and bruises on their bodies. This has to be done."
Take it seriously.”
Lin Yi nodded, then picked up the walkie-talkie and shouted: "Squadron leader, I am Lin Yi. I am requesting a change of guard so that these injured soldiers can be repaired here. Our fourth squad will go up to carry the sandbags."
Soon the news came back from the squadron leader, "Company Commander Lin, thank you for your hard work on the rescue. I just got the news that the water volume in the reservoir has dropped to 80% of its capacity. Now the water release volume is slowly reducing, and our pressure can be reduced."
.
It is expected that the flood gate will continue to be fully discharged until noon today. We now have a morning to reinforce it, so those injured soldiers can stay there to rest and wait until noon to come back."
When Lin Yi heard this, his brows relaxed a lot. The Meteorological Bureau's overall weather forecast is definitely more accurate than his own meteorological skills. The Meteorological Bureau can definitely predict the weather conditions that he can see. Then the Emergency Management Office
The most scientific method will be used to control the speed of flood discharge.
Since we now have a whole morning of breathing time, it means that the pressure is much less, so we immediately asked: "Do you still need people on the embankment? Our three reserve squads can go up."
The squadron leader knows that the reserves are also very busy. Although they are not in immediate danger, the things they do are still quite physically demanding.
Now that the reserves are brought up and the three squads of the fire squadron are put down, there is basically no merit except that it will consume more energy.
So he refused: "Captain Lin, thank you for your kindness. Let's each perform our duties. But I still have to trouble you. You must help me take care of the injured soldiers. We are on the embankment and there is really no room for us."
Space and manpower are gone.”
Lin Yi immediately agreed: "Okay, please don't worry, I will take good care of the personnel for you."
Then Lin Yi looked at the fourth squad leader and said, "Be careful here, in case there is a dike breakage. There is too much water here and it is too tidal. I have to move the injured to private houses first."
The fourth squad leader immediately agreed, but then whispered: "Company Commander Lin, did you know there are fish farmers in our reservoir?"
fish?
Lin Yi was a little confused when he asked, "Isn't it normal to raise fish in the reservoir? It can not only generate income but also protect the ecology. Is there any problem with this?"
The fourth squad leader looked around and found that no one was staring at him. Then he took out a fishing net, which contained several big fish. "Captain Lin, the continuous discharge of floods these days has caused most of the fish in the reservoir to escape."
, and the gravel and twig area we spent all night building last night has become the best hiding place for fish.
When I went to rescue people just now, I just passed by this area and stepped on several fish. I thought, since this is a wild place, these fish are naturally ownerless, so why not stew fish soup for the wounded?
Drinking, it shouldn’t be a violation of discipline.”
Lin Yi saw the little thought of the fourth squad leader and put his hand out to put the fish into the rubber boat, "I understand. After the fish is ready, come over in batches to eat. I have been busy all night and my energy has been exhausted several times. Yes
