At the outlet of Bapan Gorge, water flows from top to bottom. It should have been unimpeded, but a huge boulder was placed across several outlets. An iron chain tied under the boulder was swept into the outlet by the current. I don’t know where it came from.
The carcasses of livestock and debris that were washed down were all blocked on both sides of the boulders, which directly blocked the water outlet. It was like a blocked toilet. Only a thin stream of water could flow out slowly, and most of the water was blocked.
Backlogged.
Not to mention that this kind of thing only happens once in a hundred years, I'm afraid I haven't heard of it since the people on both sides of the Yellow River. It would take you half a day to measure the size of a boulder that is tens of meters long. If it stands there, it will not be several stories high.
.
The stationmaster of Bapanling Hydropower Station stroked his forehead and said with dull eyes: "Am I crazy or are you crazy? Can anyone tell me again, what is blocking the water outlet? What a huge boulder.
A huge boulder? Several tens of meters. Is this possible? Who would believe this? What a big joke."
The two divers looked at each other in confusion, and then said with a wry smile: "Stationmaster, you are not crazy and neither are we. It is the stone that is crazy. That stone is indeed blocking the water outlet. We have seen it."
I’ve touched it and touched it”
"Crazy stone?" The stationmaster sighed and asked again: "Is there an iron chain on the boulder?"
"Uh..." The diver said bravely: "Yes, there is an iron chain tied under the boulder."
"Crazy, crazy, let's all go crazy." The stationmaster looked confused for a long time, waved his hands tremblingly, and said: "Let the engineering department prepare, use a large crane to move the stones, and organize professionals to come over.
exploration"
The webmaster knows that he is not crazy, and the people on the site are not crazy either. The one who is crazy may be God. What the hell, where did that stone come from?
The surface of the river can be described as "turbulent", but the bottom of the river is usually very calm. Even if there is a violent storm above, there will not be much fluctuation at the bottom. Bodies or debris can still be caught by the current.
It is washed away, but it is absolutely impossible for a stone weighing more than a tonnage to be carried away by the current.
"It's really like hell." As if to emphasize the extent of his confusion, the webmaster repeated this sentence angrily.
Three 100-ton cranes were urgently transferred to the Babanxia Hydropower Station. The crane's boom was supported on the water, and the lifting ring was tied to a steel wire rope with a diameter of two centimeters. Don't look at it. The wire rope is not too thick, but it is just this.
This grade of rope can easily move a fully loaded Boeing 747 without breaking.
The steel wire rope was sent underwater and then wrapped around one end of the boulder. When everything was ready, the three cranes started working at full power at the same time, and the steel wire rope tightened in an instant with a "swish".
"Boom, boom, boom." The crane used the accelerator to pull the wire rope with all its strength and then drove the boulder to the water. Three 100-ton cranes worked together. If the wire rope was wrapped around a seven-story building, the three crane arms would
Even the building was cut off, but the stone under the Babanxia Hydropower Station remained motionless.
The wheels of the crane gripped the ground. A burning smell came from the rapid rotation, and several huge holes were dug out on the ground. The crane's body trembled under the huge load, and black smoke emitted from the engine.
"Stop, stop, stop." An expert waved his hand and told the crane driver to stop lifting. Then he told the station manager very seriously: "This plan will definitely not work. The crane is not strong enough to lift the stone. It is too heavy and it will not work at all."
"
"What if we bring in two more cars? Two cars instead of three cars?" the stationmaster asked.
The expert shook his head and said: "The weight of the stone itself is one thing. The current water depth is more than 20 meters and less than 30 meters. You know the water pressure that a stone with a length of dozens of meters has to withstand. I don't even need to tell you.
The weight of the stone plus the pressure from the water pressure
, what is the concept of this sum? I guess it won’t work even if you bring in ten trucks. If once the stone is brought out of the water, only one crane arm cannot bear the weight and breaks, all the cranes will be brought.
If you go into the water, it will be even more troublesome."
The webmaster rubbed his head with a headache and asked: "This plan doesn't work..."
"Then implement the second plan." The expert held his eyes on the bridge of his nose and said, "Let's blast underwater."
The corner of the stationmaster's mouth twitched, his head buzzed, and he suddenly felt a little dizzy. Underwater blasting is not difficult, but the difficulty is that this stone is stuck on the outlet of the dam. If the underwater blasting occurs even a little bit,
The mistake caused damage to the hydropower station while blowing up rocks. A bolt from the blue could kill everyone involved.
The value of the Babanxia Hydropower Station, built in the late 1960s, is in the hundreds of millions. Moreover, it is responsible for most of Gansu's electricity. If there is a problem with the hydropower station, how many people in Gansu will have to eat in the dark at night?
The webmaster tremblingly took out a cigarette and lit it, smoking silently. After smoking several cigarettes in a row, he finally made up his mind: "I will report it to the government and the Ministry of Water Resources..."
One day later, a deputy minister of the Ministry of Water Resources led a team to the Babanxia Hydropower Station in an emergency. After listening to the report, a team of experts was organized to conduct demonstrations, on-site surveys and underwater tests.
All kinds of twists and turns!
Two days later, a plan with a success rate of over 89% was produced.
On the third day, explosives were buried under the boulder and were ready to be detonated.
The minister of the Ministry of Water Resources, the station director of the hydropower station, and the local government officials all had sweaty palms, sweaty foreheads, and sweaty backs. In general, these people were almost soaked through.
The stone was blown away and the hydropower station was not damaged. Their plan was successful and it was a false alarm.
Exploding the rocks, the plan to damage the hydropower station failed, and they almost had to go to the superiors with their heads raised. Someone must be responsible for this matter, whether it is a scapegoat or bad luck, in short, someone has to take this matter
The blame has been taken.
However, no one has thought of a seemingly outrageous question, that is, what if the stone is not exploded?
"10,9,8,7······"
The sound of the countdown came, and several sounds of swallowing saliva made the atmosphere suddenly tense.
After the "Boom" countdown reached one, the underwater explosives buried under the boulders were detonated, and several water columns tens of meters high were lifted up, and then fell from the air like rain.
After a period of silence, Tao Dehua stretched his neck out from the hydrological monitoring station and said excitedly: "Stationmaster, leaders, the monitoring shows that the dam is not damaged, not at all."
The scene was filled with cheers and people were excited!
The leader of the Ministry of Water Resources shook hands with the construction workers on site one after another and said: "Comrades performed well and did a good job. Under the leadership of the party, we overcame many difficulties and finally conquered this once-in-a-century problem. It is gratifying to congratulate...
·····”
When leading Balabala, several divers waited for the water to calm down before diving into the water to investigate the situation. When they emerged from the water, they were all shocked.
