At the outlet of Bapanxia, the water flow flows from top to bottom, which should be unimpeded, but a boulder is across the top of several outlets, and an iron chain is tied under the boulder and is swept into the outlet by the water, and the carcasses and debris of the livestock that have washed down from nowhere are all blocked on both sides of the boulder side, directly causing the water outlet to be blocked, which is like a flush toilet blocked only a thin stream of water can flow out slowly, and most of the water is backlogged.
Not to mention this kind of thing once in a hundred years, I'm afraid that people on both sides of the Yellow River have not heard of it since there were people, how big the boulder is dozens of meters long, you have to measure it for half a day with a ruler, and even if it is not a few stories high, it is not a few floors high.
The stationmaster of the Bapanling Hydropower Station stroked his forehead and said with blank eyes: "Am I crazy or you are crazy, can anyone tell me again, what is the water outlet blocked?"
Boulders, how big boulders?
Tens of meters, is this possible?
Who will believe this?
What to open Big joke" The two divers looked at each other with a wry smile: "Stationmaster, you are not crazy, we are not crazy, it is the stone that is crazy, the stone is indeed blocked at the water outlet, we have seen and touched it."
"Crazy stones?"
The stationmaster sighed and asked again, "Is there still a chain on the boulder?"
” "Forehead ·······" The diver stubbornly said, "Yes, there is an iron chain tied under the boulder."
"Crazy, crazy, let's all go crazy" The stationmaster's face was entangled for a long time, his hands trembled, and he waved weakly and said: "Let the engineering department prepare, use a large crane to move the stones, and organize professionals to come over to explore" The stationmaster knows that he is not crazy, and the people in the station are not crazy, and the one who is crazy may be God, what the hell is this, 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 it is a violent storm above, the bottom of the rain will not fluctuate much, and the corpses or debris can be washed away by the current, but the weight of a piece is in tonnage The stones on it could never be carried away by the current.
"What the hell is alive and hell" seemed to want to emphasize his degree of confusion, and the stationmaster repeated this sentence again angrily.
Three hundred-ton cranes were urgently transferred to the Bapanxia Hydropower Station, the crane boom was supported to the water, and the ring was tied to a wire rope with a diameter of two centimeters, you don't see that the wire rope is not too thick, but the rope at this level can easily drive a fully loaded Boeing 747 It won't break.
The wire rope is sent underwater and then wound to one of the boulders, and when everything is ready, the three cranes are running at full power at the same time, and the wire rope is instantly tightened.
"Boom, boom, boom" crane boom throttle to pull the wire rope and then drive the boulder to the water surface, three 100-ton cranes together to exert force, if the wire rope is wrapped around a seven-storey building, three booms can cut off the building to lazy waist, but this stone under the Bapanxia Hydropower Station But his head remained unmoved.
The wheels of the crane grabbed the ground, and a scorched smell came under the rapid rotation, and several huge pits were directly dug out of 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 applied very seriously and said to the stationmaster: "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 can't be three?"
The stationmaster asked.
The expert shook his head and said: "The weight of the stone itself is one thing, the current water depth is less than twenty meters, and the water pressure that the stone is tens of meters long has to bear is what I don't know, the weight of the stone plus the pressure brought by the water pressure, this sum is."
What is the concept?
I don't think it will work if you bring ten trucks to the surface, and if only one of the booms breaks if the stones are brought out of the water, all the cranes will be brought into the water, which will be even more troublesome."
The stationmaster 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: "Underwater blasting" The corners of the stationmaster's mouth twitched, his head buzzed, and he was suddenly a little dizzy, there is no difficulty in underwater blasting, but the difficulty is that this stone is stuck in the outlet of the dam, if there is even a slight mistake in underwater blasting, it will damage the hydropower station while blasting the stones A thunderbolt on a sunny day can kill everyone involved.
How much is the value of this Bapanxia hydropower station, which was built in the late 60s, in the hundreds of millions, and it also bears most of the electricity in Gansu.
The stationmaster took out a cigarette and smoked it silently, and 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 vice minister of the Ministry of Water Resources led a team to rush to the Bapanxia Hydropower Station, and after listening to the report, a special expert group was organized to conduct demonstrations, on-site investigations, and underwater tests.
All kinds of tossing!
Two days later, a program with an inferred functional rate of more than 89 percent was taken out.
On the third day, explosives were buried under the boulder and were ready to detonate.
The minister of the Ministry of Water Resources, the head of the hydropower station, and the local government officials were all sweating with their palms, their brains, and their backs.
Blowing up the stones, the hydropower station was not damaged, their plan was successful, a false alarm.
Blowing up the stones, the plan to damage the hydropower station was not successful, and they almost all had to go to the superiors with their heads up, and someone had to be responsible for this matter, whether it was a scapegoat or bad luck, in short, someone had to carry the pot.
However, no one thought of a seemingly outrageous question, that is, what if the stone was not blown up?
“10，9，8，7······” The countdown sound came, and several spitting movements made the atmosphere suddenly tense.
After the countdown to the "boom" arrived, the explosives buried under the boulder were detonated, and several columns of water tens of meters high were lifted, and then fell from mid-air like rain.
After a period of silence, Tao Dehua's neck stretched out from the hydrological monitoring station and said excitedly: "Station master, leaders, the monitoring shows that the dam is not damaged, not damaged at all."
The scene was full of cheers and people's hearts were excited!
The leaders of the Ministry of Water Resources shook hands with the construction workers on the site in turn and said: "The comrades have performed well and done well, and under the leadership of the party, we have overcome many difficulties and finally overcome this once-in-a-century problem, which is gratifying and congratulating·······."
When leading Balabala, several divers waited for the surface to calm down and then dived into the water to check the situation, and when they emerged from the water, they were all stunned.
