"I, grass" Tao Dehua pouted his ass and looked at the hydrological monitoring of the computer screen.
Hydrological monitoring is not only to monitor the depth of water, but also includes changes in water, quality and other changes, the hydrological monitoring of the Bapanxia Hydropower Station has monitored the water conditions of the hydropower station, every 100 kilometers or so upstream, there are several monitoring points, the total length is about 500 kilometers 。
In the computer monitoring in front of Tao Dehua, the hydrological monitoring is continuing to rise, I don't know when it has been approaching the warning water level from just after the critical point, this situation only occurs in the flood season in May, and has not appeared for a month now.
And the water quality has also changed, and it is unusually turbid, showing a lot of debris.
"The weather forecast didn't say that there had been heavy rain recently?"
Tao Dehua turned his head to look at the night sky outside the office with a confused expression, and the stars were winking mischievously at him.
The door of the office was slammed open, and a woman in her fifties asked anxiously, "Xiao Tao, what's going on with hydrological monitoring?"
” Tao Dehua still didn't come out of the blindfold, pointed to the computer, and said in confusion: "It seems to be about to explode?"
” The woman turned her head to look at the screen and said anxiously: "Oh no, no, I don't know what's going on, the flood outlet and the power station outlet are blocked, and the waterway is blocked and the waterproof is very slow."
Tao Dehua asked in surprise, "How can it be blocked?"
I wonder how the water level can suddenly continue to rise since there has been no heavy rain reported recently."
"Oh, you're still weird, hurry up and call the stationmaster, if the water level rises again, it will overflow the dam, and something big will happen," said the middle-aged woman, jumping to her feet.
Tao Dehua hurriedly picked up the phone to report, and it didn't take long for the stationmaster of the Bapanxia Hydropower Station and several other main leaders to crawl out of the bed and quickly arrive at their posts.
The stationmaster furrowed his brows and asked very puzzled, "What's the matter?"
How come the flood outlet and the water outlet are suddenly blocked, is it possible that they are all blocked?
” "Stationmaster, it's not all blocked, but there may only be one or two openings left, so I hurriedly reported to you" The stationmaster pointed to Tao Dehua and asked, "What is the current situation of the water level?"
” "The water level at the hydropower station has already begun to reach the warning level, and the water level is still rising 200 kilometers away, the rise is flat for 300 kilometers, and there is nothing abnormal at the monitoring point for 500 kilometers," Tao Dehua said.
"How to do it, how to do it······" The stationmaster anxiously walked back and forth in the office, a little undecided, and the cigarette in his hand was broken.
"Stationmaster, you have to order the water to be released, and if it's too late, the dam will overflow," someone reminded.
The stationmaster pursed his lips and said with a slightly pale face: "Hurry up and contact the management personnel of the water station in the middle and lower reaches, and say that the Bapanxia Hydropower Station is overflowing, and I will report to the leader."
Hydropower stations are not just open and release water, which involves a very cumbersome process, and it is easy to cause big problems if you are not careful.
Except for when there is a big flood or drought, the flow speed of the Yellow River and the Yangtze River, including the water level, has a standard, and the standard regulations are very strict, neither allowing the water level to be too low, nor allowing the water level to approach the warning level, and has been maintained a stable direction.
Except, of course, natural causes.
For example, according to the current situation, the Bapanxia Hydropower Station is upstream, if the water level suddenly rises and needs to release water, the river in the middle reaches will quickly be full of water If the downstream is now cut off, the middle and upper reaches will be released at the same time, and if someone is in the river at this time, it may suddenly be washed away by the flood.
This is just the simplest situation, the whole Yellow River does not know how many projects, such as hydropower stations, sluices, flood control measures, etc., if you suddenly release water, God knows what will happen, no one can predict it.
Therefore, there is an emergency situation in Bapanxia, but they absolutely do not dare to release water without authorization, at least they have to contact all the water stations and some engineering facilities from the upstream to the middle reaches and get their permission.
Human life is at stake, property loss, no one dares to take it lightly!
For a time, the Bapanling Hydropower Station was full of rumors.
"Let's release the water" After about ten minutes, the hydrological monitoring on the computer has exceeded the warning water level, and the stationmaster spit out three words after a long sigh.
The flood outlet and the outlet were opened at the same time, but there was no surprise only that the water level was still high, and looking out from the office window, the water flow at the outlet was like a child urinating, very small and uniform.
"What is the cause of the blockage, have you found out?"
asked the stationmaster Tie with a blushing face.
"Lots of sediment and a lot of debris ······" Tao Dehua said with some uncertainty: "Many of these debris are the carcasses of livestock, many, many, but what I can't figure out is that there is a very obvious blockage zone in the middle of the sluice gate, and the volume is very large The water is too muddy and sandy, and there are all the debris piled up there, and I can't see what it is, but it's a little, a bit like ······" "Don't ramble, say," the stationmaster said with a frown.
"It's a bit like a ship, and it's definitely over 100 meters," Tao Dehua said.
"What are you kidding, even a sunken ship can't be blown over" Tao Dehua whispered: "I only said that it was like a ship, who knows what it is" The stationmaster asked, "Can't figure it out?"
” "The water is too mixed and the water level is high" "The gates are all open, and we are trying to release the flood water, and if we delay it, the dam will be flooded, and we are all waiting to take the blame and resign," the stationmaster said helplessly.
An hour later, engineers and water conservancy experts were in place, and finally two more gates were opened at dawn, and the water level began to drop slowly, which was considered to temporarily keep the hydropower station from being washed away by the flood.
But the blockage zone in the middle of the dam that Tao Dehua mentioned earlier still exists, and there is no way to solve it.
After daybreak, the water level dropped to the most dangerous situation, and then two boats sailed to the middle of the river to salvage the accumulated debris in the water, and several divers sank under the water to investigate the situation.
Half an hour after the divers entered the water, the situation was temporarily clarified.
"A boulder of more than 100 meters was across the outlet of the dam, and an iron chain was caught in the boulder and wrapped around the gate" The stationmaster, Tao Dehua and all the people were stunned in disbelief: "How could such a large stone be washed over······"
