After entering the hydropower station, the air became relatively drier. Liang Jian and the others quickly took off their raincoats. The hydropower station employees brought them work clothes to change into. After changing out of their soaked clothes, they finally felt better.
Liang Jian took a sip of the hot tea sent by the staff, and then gathered in a small conference room with Deng Dawei, the hydropower station director, Yan Guoqiang and others. In the center of the conference room, there was a sand table with green dragon plates surrounding it.
Picture of nearby rivers and mountains. Liang Jian also didn’t expect there to be a sand table here, and was surprised. However, he was surprised. The most important thing at the moment is to find a way to solve the problem of the river. On the sand table, each river channel is very clear.
, Liang Jian took a glance and found that more than half of the river downstream of Qinglongtan had red flags. The rest, many of them were yellow flags, and only a few were green. Liang Jian asked: "What does this red flag mean?"
The webmaster replied: "The red flag means that the river will not be restored in the short term."
When Liang Jian heard this, he frowned. On the sand table, none of the major rivers had red flags. The other minor rivers were also covered with red flags. Those without red flags basically had yellow flags.
, the green period is only a handful. Liang Jian pointed to the yellow flag, and the stationmaster hurriedly explained: "This means that the river is blocked, but it is not very serious. The green period means that the current situation is not bad."
Liang Jian glanced at the few greens among the full reds and yellows, and felt annoyed. He couldn't help but glance at Yan Guoqiang again. Yan Guoqiang lowered his head, and the stationmaster of the hydropower station also lowered his head.
Liang Jian snorted and turned to ask Deng Dawei, director of the Water Conservancy Bureau: "Let's see if there is any way to solve two problems first to relieve the water level pressure."
Deng Dawei nodded and came forward to study the sand table carefully. Liang Jian also took a closer look. The downstream rivers were complicated, and there were several underground rivers that passed through the mountains and turned to the ground. Liang Jian looked at it for a while,
He turned around and asked the director of the hydropower station: "Do you have any on-site pictures of the areas where these major rivers have been washed away?"
When the hydropower station director heard this, he immediately nodded and replied: "Yes, I'll get it right away."
He quickly brought the computer and found the pictures. Liang Jian looked around and found that most of them were seriously blocked because the nearby mountains were rocky and lacked soil and vegetation. Most of these rivers were on natural foundations.
It was slightly processed. The washed away place was either a huge boulder that fell from the mountain and stretched across the entire river, which could not be moved without a crane, or trees, rocks and sand gathered together in one place, or even worse, both sides of the river collapsed.
Blocked, the river water overflowed from both sides, flooding the adjacent farmland, washing away the vegetation and soil on the farmland, and causing blockage of the downstream river. In short, it was like a butterfly effect, causing a chain reaction and paralyzing the entire river.
After looking around, Liang Jian had to realize that if he wanted to restore the flood discharge capacity of those major rivers, he would probably have to bypass the washed-out area and build another river next to it. But this project is very large, and now
The road conditions are so bad that it is difficult for construction vehicles to drive in at the moment, so we basically have to rely on manual labor. As a result, it will definitely not be completed in a short time.
Undoubtedly, this direction has reached a dead end. Liang Jian once again turned his attention to the sand table and looked up. Since the downstream was not possible, he would look for a way upstream.
In addition to rain, the bigger reason why the water level in Qinglongtan is getting higher and higher is because the water from the mountains on both sides is constantly collecting and flowing into Qinglongtan. If you can find a way to temporarily block this water, maybe try to
Let Qinglongtan relax for a while.
Liang Jian squinted his eyes and searched carefully upstream of Qinglongtan. Suddenly his eyes lit up and he pointed at two locations upstream of Qinglongtan and asked, "Can you think of a solution at these two places?"
The valley where Qinglongtan is located is like a gourd. The difference is that there is an extra mountain in the middle of the second half of the gourd. It is long and strip-shaped. One end is right at the waist of the gourd, and the other end is slightly behind the middle of the second half.
Location.
The place Liang Jian pointed to happened to be the place where the waist was divided into two halves by the long mountain.
The director of the hydropower station looked at Liang Jian with a blank look on his face. Liang Jian asked: "Is the water level in this place deep?"
The head of the hydropower station replied: "Usually it's not too deep, it's probably only as high as a person, but now the water level has risen a lot compared to usual. The water level here is now at least two meters."
The water level of two meters is not very deep, let alone not deep. Once a person goes in, there is no end. Liang Jian hesitated and continued to look up. At the end of the gourd, the mountains on both sides joined together.
, there was nothing to consider. Liang Jian thought for a while and decided to use his previous idea. He said, "I have an idea. You guys should listen to it and see if it's feasible." As he said that, he clicked on what he had just clicked.
He said: "I think we can find a way to build a temporary dam at these two locations to separate Qinglongtan and divide it into two parts, the front and the back. In this case, the pressure of the front dam will be relatively
Reduction. After the pressure is reduced, we may consider opening a small gate to discharge floods. In this situation, it is no longer possible to completely preserve the surrounding farmland. We can only abandon the car to save the troops. First, we must
Ensure the safety of people nearby."
After Liang Jian finished speaking, he looked at Deng Dawei and the others. A few seconds later, Deng Dawei was the first to speak. He asked the hydropower station director: "What is the total length of these two positions?"
The head of the hydropower station replied: "According to the usual water level, the total width of the water surface is about two hundred meters, but now the water level has been more than two meters higher, and it must be more than that."
After hearing this, the station manager of the hydropower station thought for a moment and said to Liang Jian: "We are short of manpower now. It may be difficult to cut off the length of more than 200 meters."
Liang Jian said: "I have just asked my secretary to notify the city and ask the city to organize manpower to come over. It should take at least three hours to reach the outside of the valley. If the road outside the valley can be opened..." said
At this point, Liang Jian suddenly stopped. His brows gradually furrowed, and he caught the flash of light that just flashed in his head. He suddenly raised his head and asked the stationmaster of the hydropower station: "In addition to the incoming road in the valley here,
, there’s nothing else, right?”
The station manager of the hydropower station was stunned for a few seconds. After a few seconds, he came to his senses and replied: "No more, there is only one exit."
Liang Jian suddenly laughed and said: "We don't block the inside, we block the outside. We block the mouth of the valley and expand Qinglongtan. The flood discharge channel has been basically destroyed, so if we discharge the flood, most of the water will pass through.
This valley leads to the outside, and only a small part of it leads to the outside through the destroyed river channel. In this case, if we block the entrance of the valley, will there be less water flowing outside?"
A group of people stood there, frowning and thinking about Liang Jian's words. Liang Jian waited patiently. After a while, Deng Dawei nodded and said: "This method is OK."
After the words fell, the director of the hydropower station objected: "This won't work. If this happens, almost all the crop land in the valley will be destroyed."
Liang Jian glanced at him and asked: "Let me ask you, if the rain doesn't stop, how long can the Qinglongtan dam last?"
When the station manager of the hydropower station heard this question, his face suddenly turned ugly. He hesitated for a while before replying: "If the rain doesn't stop, Qinglongtan will have to open the floodgates to release water no later than tomorrow morning, otherwise the dam will be flooded."
It will be dangerous." After finishing speaking, he paused and added: "At that time, I am afraid that at least five gates will have to be opened. Moreover, the impact brought by the five gates will also have a certain impact on the dam.
I...can't guarantee the impact."
Liang Jian originally just wanted to convince him, but when the answer was placed in front of him, his heart sank. Liang Jian sighed and then continued: "If we don't take measures now, then by tomorrow morning, it will be very difficult."
What may be destroyed is not just a little cultivated land in this valley, but it may also affect the lives and safety of many people, which is something you and I cannot afford!"
The head of the hydropower station lowered his head and said nothing. Liang Jian shook his head and sighed: "Let's make it this way. I will ask the secretary to inform Comrade Hong Wei and others outside now to organize the villagers to help before the city personnel arrive.
, block the entrance of the valley. In addition..." Liang Jian looked at the hydropower station director: "You should inform the outside immediately that Qinglongtan may need flood discharge at any time, and ask Changqing District Government personnel to quickly arrange for the evacuation of surrounding villagers to avoid flooding.
Casualties.”
The director of the hydropower station looked guilty. After listening to Liang Jian's words, he immediately prepared to go out to make arrangements. As he was about to go out, Liang Jian stopped him and said, "The matter has reached this point, and I don't want to hold anyone responsible now. But this dam
, we must keep it no matter what.”
Upon hearing this, the director of the hydropower station suddenly gritted his teeth, straightened his body, and shouted: "Yes! Secretary, don't worry, I swear, I will find a way to save it. If I can't save it, I will be washed away by the water together with the dam!"
"
Liang Jian waved his hand: "It's useless to say these cruel words. If we flush you away, we won't be able to save those people. Okay, hurry up and do what you need to do."
As soon as the station manager of the hydropower station left, Shen Lianqing walked in. Liang Jian suddenly wanted to know the time, so he asked Shen Lianqing: "What time is it now?" He had forgotten that he had a watch on his hand.
Shen Lianqing replied: "It's six o'clock." Liang Jian was stunned and asked again: "What time did we set off from the city?"
"It's less than one o'clock at ten o'clock." Shen Lianqing said.
Liang Jian suddenly remembered that he had not even eaten during this busy day. When he thought of it, he immediately felt hungry. When he felt hungry, he immediately felt hungry, and his chest pressed against his back, and he heard a grunting sound.
.
Liang Jian touched his belly. Deng Dawei didn't eat either. When Liang Jian was hungry, he also felt the same. Yan Guoqiang had eaten, but he also heard the sound. He hurriedly said: "I'll go out and take a look.
See if there are any dinner arrangements in their canteen."
Liang Jian stopped him and told him: "Time is tight, so just make some. It's best to have steamed buns or something that you can take away."
Yan Guoqiang was stunned for a moment, then nodded and said yes, and went out.
There were no steamed buns in the cafeteria, but there were rice dumplings. Yan Guoqiang asked them to boil some eggs. Each person was given two rice dumplings and two eggs.
