At the water outlet of Bapanxia, ??the water flowed from top to bottom. It should have been unimpeded, but a huge boulder lay across several water outlets. An iron chain was tied under the boulder and was swept into the water outlet. I don¡¯t know where it came from. The corpses of livestock and sundries washed down were all blocked on both sides of the boulder, which directly blocked the water outlet. This is like a blocked toilet, only a thin stream can flow out slowly, and most of the water is blocked. Backlog lived.
Don't say that this kind of thing happens once in a hundred years. I'm afraid that there are people on both sides of the Yellow River who have never heard of it. How big is a boulder tens of meters long? It takes a long time to measure it with a ruler. up.
The head of the Bapanling Hydropower Station rubbed his forehead and said with blank eyes: "Am I crazy or are you crazy? Who can tell me again, what blocked the water outlet? How big is the boulder?" The boulder? Tens of meters, is this possible? Who would believe this? What kind of big joke?"
The two divers looked at each other, and then said with a wry smile: "Station Master, you are not crazy and we are not crazy, it is the stone that is crazy, that stone is indeed blocking the water outlet, we have seen it touched and touched"
"Is it a crazy stone?" The station master sighed, and asked again: "Is there an iron chain on the boulder?"
"Eh" the diver said bravely, "Yes, there is an iron chain tied under the boulder"
"Crazy, crazy, are we all crazy?" The stationmaster's face was tangled for a long time, his hands were trembling, and he waved weakly and said: "Let the engineering department prepare, use a large crane to move the stones, and at the same time organize professionals to come over exploration"
The station master knows that he is not crazy, and the people in the station are not crazy. It may be God who is crazy. 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 storm above, the bottom will not fluctuate much, and corpses or debris can still be blown away by the water. It was washed away, but it is absolutely impossible for a stone weighing more than a ton to be taken away by the current.
"Damn it!" It seemed that he wanted to emphasize his degree of confusion, and the station master repeated this sentence angrily again.
Three 100-ton cranes were urgently transferred to the Bapanxia Hydropower Station. The booms of the cranes were supported on the water surface, and the lifting rings were tied with a steel wire rope with a diameter of two centimeters. Don¡¯t look at the steel wire rope. It¡¯s not too thick, but this The level rope can easily drive a fully loaded Boeing 747 without breaking.
The steel wire rope was sent underwater and then wound around one end of the boulder. When everything was ready, the three cranes were fully powered at the same time, and the steel wire rope was taut in an instant.
"Boom, boom, boom" the cranes slammed the throttle to pull the wire rope with all their strength and then drove the boulder to the water surface. Three hundred-ton cranes worked together. If the wire rope was wrapped around a seven-story building, three booms would It can cut off the building, but the stone under the Bapanxia Hydropower Station is still motionless.
The wheels of the crane gripped the ground, and there was a burning smell under the rapid rotation, and several huge pits were dug out in the ground, and the body of the crane trembled under the huge load, and the engine emitted black smoke.
"Stop, stop, stop." An expert waved his hand to tell the crane driver to stop lifting, and then told the station master very seriously: "This plan will definitely not work. The strength of the crane is not enough to lift the stone. It is too heavy. It will not work at all." "
"What if two more cars are transferred, two or three?" asked the station master.
The expert shook his head and said: "The weight of the stone itself is one aspect. The current water depth is more than 20 meters to less than 30 meters. I don't tell you how much water pressure a stone with a length of tens of meters must bear. The weight of the stone plus the pressure brought by the water pressure, what is the concept of this sum? I don¡¯t think it will work even if you call in ten cars. If once the stone is brought out of the water, only one crane arm can¡¯t bear it. If it breaks due to the weight, all the cranes will be brought into the water, which is even more troublesome.¡±
The station master rubbed his head with a headache and asked: "This plan doesn't work"
"Then implement the second plan." The expert helped his eyes on the bridge of his nose and said, "Let's blast underwater."
The corner of the station master¡¯s mouth twitched, his head buzzed, and he felt a little dizzy. Underwater blasting is not difficult, but the difficulty is that this rock is stuck on the water outlet of the dam. The mistake caused the damage to the hydropower station while blowing up the rocks, and a thunderbolt from the blue can kill all the people involved.
How much is the value of this Bapanxia hydropower station built in the late 1960s, in billions, and it also undertakes most of the electricity and hydropower in Gansu.?If something goes wrong, how many people in Gansu will have to eat in the dark at night?
The station master tremblingly took out the cigarette and lit it, smoking silently. After smoking several cigarettes in a row, he finally made up his mind: "I will report to the government and the Ministry of Water Resources"
A day later, a deputy minister of the Ministry of Water Resources led a team to the Bapanxia Hydropower Station in an emergency. After listening to the report, a special expert group was organized to conduct demonstrations, on-site investigations, and underwater tests.
All kinds of toss!
Two days later, a plan with a success rate of more than 89% after inference was presented.
On the third day, explosives were buried under the boulder, ready to detonate.
The minister of the Ministry of Water Resources, the station master of the hydropower station, and the officials of the local government were all sweaty on their palms, foreheads, and backs. Generally speaking, these people were almost drenched.
Exploding the stone, the hydropower station was not damaged. Their plan was successful, and it was a false alarm.
The stone was blown away, and the plan for damaging the hydropower station was unsuccessful. They almost all had to face their superiors with their heads up. Someone must be responsible for this matter. The pot is back.
However, no one thought of a seemingly outrageous question, that is, what if the stone is not blasted?
"10, 9, 8, 7"
The sound of the countdown came, and several swallowing movements made the atmosphere suddenly tense.
After the countdown to "Boom", the explosives buried underwater under the boulder were detonated, several jets of water tens of meters high were lifted up, and then fell from midair like rain.
After a while of silence, Tao Dehua's neck stretched out from the hydrological monitoring station, and he said excitedly: "Station Master, leaders, the monitoring shows that the dam is not damaged, not at all."
The scene was full of cheers, and the hearts of the people were excited!
The leader of the Ministry of Water Resources shook hands with the on-site construction workers one by one and said: "Comrades have performed well and done well. Under the leadership of the party, we have overcome many difficulties and finally overcome this once-in-a-century problem. Congratulations "
When leading Balabala, several divers waited for the water to calm down and dived into the water to check the situation. When they emerged from the water, they were all stunned.
