"I'm going up to the embankment to see what's going on." Fan Heng looked at the scaffolding that seemed to be in the clouds. Said to the entourage.

After hearing Fan Heng's request, both the entourage and the people from the reservoir area construction headquarters were a little panicked, the water storage height here should be more than 100 meters high, so that Fan Heng, a leader who is already in his fifties and has no experience in going out to work, will personally go to the embankment to check the situation, and no one will be sure in his heart.

"Vice Premier Fan, it's too dangerous here, let's go up and take a look at the situation." The entourage said one after another.

The leaders of the reservoir area construction headquarters also discouraged, "Vice Premier Fan, although there are some cracks in the embankment, the problem is not big, and we are using filling materials to carry out a comprehensive repair, so there is really no need to go up and check again." ”

Fan Heng shook his head and said, "I was entrusted by the central government to investigate this matter, since I came, if I don't go up to take a look, how can I be down-to-earth in my heart?" ”

He didn't pay attention to what others said, found a hard hat to put on, and then, accompanied by several bodyguards, got on the scaffolding under construction, and then climbed to the place where the crack appeared in the embankment.

The retaining surface of the dam is close to the middle of the river, and the dam has been poured more than 100 meters, about 80 meters high in the middle of the dam. From top to bottom, a total of more than 20 scaffolding, which the migrant workers call the joint trough, are covered with green protective nets, like a "green centipede" array erected and attached to the middle and lower part of the dam body.

Directly below these "green centipedes", a construction trench hundreds of meters long and tens of meters deep has been excavated along the base of the dam body, and workers are busy working along the base of the dam under the deep trench.

Fan Heng and others climbed a few layers of the seam trough, only to see that there were cracks on the dam wall from top to bottom, and the width of the crack could be inserted into the palm of an adult's hand. After asking the construction workers, these are the cracks that are waiting to be treated after being discovered, because they want to add all kinds of new materials to the grouting, so they use a hand-held cutting machine to scrape off the surface waterproof cement layer next to the crack mouth a few centimeters thick and dozens of centimeters wide, and then cut some of the seams to facilitate construction.

At the top of the "green centipede" is a huge mid-level flood vent, where a scaffolding platform walkway is erected, which is in the middle of the dam and you can see the seams carved out from the top of the dam down the dam body. Those have been processed, the workers say.

A construction worker told Fan Heng that the reason for the cracks was that there was something wrong with the partition material between each pouring section and the section, and there may also be something wrong with the foundation below, but the specific cause still needs to be identified by experts.

The dam has been fully closed since its construction, and the quality of the dam is unknown. This time it was poked out, and it was first spread by the Internet, but it must be difficult for ordinary people to distinguish the authenticity. It's all just rumors.

A deputy general manager of the construction company followed closely behind Fan Heng and explained to him, "This is only a shallow crack on the surface, and it will not affect the safety of the dam." Cracks in dams are inevitable in all hydropower projects at home and abroad. Cracks in large volumes of concrete are difficult to completely avoid in dam pouring. As the dam with the largest amount of concrete poured in the world, cracks in the dam are not immune to continuous high-intensity construction. ”

Another expert who rushed from Beijing in advance also said, "Large-volume concrete pouring, unlike ordinary thin-walled structures, the problem of pouring temperature is quite complicated, because it is very large and high, and the concrete will be heated." Although comprehensive measures have been taken to cool the low-temperature concrete in terms of temperature control, after all, the maximum temperature of the concrete is relatively high, and the minimum temperature of the dam is somewhat low in the case of change, resulting in cracks in the large-volume concrete after the temperature difference. Therefore, we regard the repair of concrete cracks and other repairs in hydropower construction as the last process in concrete construction, which is only a process, and it is impossible to complete the dam without any defects. ”

Fan Heng nodded. On this issue, he also consulted relevant water conservancy experts before he came, but because the entire project has almost included well-known water conservancy experts from all over the country, it is obviously difficult to hear any different opinions at this time.

At the beginning of the feasibility study of the project, the flood control team proposed that in order to achieve the expected flood prevention target, the flood control reservoir capacity should be at least 25 billion cubic meters. The project proposal approved by the National People's Congress has a flood control reservoir capacity of only 22.1 billion cubic meters, which is already less than the requirements of the flood control group.

Later, teachers and students from the Department of Water Conservancy of Tsinghua University recalculated the capacity of the flood control reservoir and concluded that the flood control capacity of the reservoir was less than 20 billion cubic meters. Therefore, the experts also suggested that the flood control limit water level should be lowered from 145 meters above sea level to 135 meters above sea level to compensate for the loss of flood control reservoir capacity caused by the miscalculation, and the measure taken in this way was to raise the threshold of the dam locks.

However, flood control is an important role of the dam and the main goal of the project, and if the flood protection benefit is not realized, it is tantamount to admitting that the project is somewhat disappointing.

The dam locks have to raise the threshold, and most of the freight will be interrupted here, relying on mechanical dam overturning. Before his death, the prime minister said that if the Yangtze River dam is built, if it causes the Yangtze River shipping to be interrupted, the dam will be blown up. Although I don't know whether this is true or not, there is always this kind of saying, if this problem can be solved, if it can't be solved, it will make people very entangled, after all, the dam has spent tens of billions of yuan, and the investment after completion is close to 200 billion, if such a large project can not be satisfied, it is indeed impossible to explain.

If only the problem of power generation is taken into account, then the construction of several nuclear power plants is more than sufficient. The investment is definitely not that large, and the time, energy, manpower and material resources consumed will definitely not be so much.

After all, after the dam was built, many of the original scenery and scenery no longer existed, which is still very regrettable.

Fan Heng looked carefully at the embankment for a morning, at this time it was very hot, the weather was extremely hot, and the group felt that the heat was unbearable, so he left from the embankment, and when he left, he still took a lot of field investigation pictures at the scene as a reference, and registered the repair means and materials provided by the reservoir area construction headquarters one by one, and took a part of the samples to bring back for future reference.

After returning to the hotel to stay, the surrounding local government officials rushed over to cooperate with the newly arrived security personnel to implement the security affairs, and then several important leaders met with Fan Heng and reported on their work.

Fan Heng was very talkative at this time, and his attitude was relatively kind, and when it came to lunch, he specially instructed the hotel to arrange a few tables of banquets to entertain these people, and everyone felt that Vice Premier Fan was very easy to get along with.

When he was resting at dinner, Fan Heng felt a little heat stroke, so he asked Song Qing to take out the summer medicine tea prepared for him by Fan Wuxian to drink it.

"It's very well prepared to be disease-free, all year round. Always be able to prepare all the medicines you need at home. Song Qing said to Fan Heng.

Fan Heng nodded and said, "Wu Xi knows that I am busy with work, so I have specially prepared a lot of tonic medicines and arranged rich recipes. ”

"This time, it's very troublesome." Song Qing couldn't help mentioning the crack in the embankment.

When Fan Heng heard this topic, he couldn't help but groan for a while, and then said with emotion, "When the National People's Congress passed a resolution to build the Three Gorges Dam on the Yangtze River, the news came. The people in the reservoir area rejoiced and set off firecrackers to celebrate. Now that a few years have passed, the joy of the people in the reservoir area has long since gone with the eastward flow of the Yangtze River, and many of them may not be able to tell whether they should be happy or worried, when the old workers of the Fengjie cement factory saw that the factory they had built disappeared in an instant in the first explosion, when the peasant women in Qu Yuan's hometown had to cut down the citrus trees that were about to bear fruit, and when the immigrants in the ancient town of Dachang waved goodbye to the Wen family compound where they had lived for more than a dozen generations and went their separate ways, perhaps they did not expect a lot. Not only these ordinary people, but also the decision-makers, planners, advocates, supporters or unclear people of this project, there are also many people who have not thought of it. ”

Song Qing heard Fan Heng speak like this, and felt the helplessness in Fan Heng's words.

In the morning, the deputy general manager said more frankly, in the past few years of engineering construction, the general direction is generally good, but there are still some defects, accidents, and some accidents are still quite large. If the surface of the diversion bottom hole is uneven, the overhead below has been treated for more than a year. Of course, for the whole project, it is a small amount of locality, but it still has an impact on the progress of the project, and the impact on this year is relatively large. Because it was discovered relatively early, the treatment was basically timely, and if it was discovered before the interception, there was no time to deal with it.

When Fan Heng asked whether the dam had broken its muscles and bones, and whether it was possible to tear it down and start over, the chief engineer said that it was impossible to completely avoid cracks on the dam surface, and the question was whether it would cause harm to the dam. The cracks that have been discovered now have recently been identified by experts as not hazardous cracks. But if it is not dealt with properly, it may also develop into a harmful crack. At the same time, he also admits that in terms of forecasting, he did not expect it to develop so quickly.

Another situation is not optimistic, and only a few years after the start of construction did it come to the news that the geological disasters in the reservoir area were serious, including more than 3,000 landslides. More than 1,000 collapsed and deformed bodies. According to official media sources, there have been more than 40 major geological disasters in this area over the past 10 years or so, and there are still more than 1,500 landslides and landslides.

Nearly 1,000 of these landslides are below the 135-metre water mark at the initial stage of the project. According to a document from the Yangtze River Water Conservancy Commission, there are more than 1,300 areas in the reservoir area that are hidden from geological disasters, and more than 100 need to be dealt with.

After Fan Heng got these materials, the first thing that came to his mind was a question, the decision-makers of the project must not have known about these situations, otherwise, it would not have been possible to make such a decision.

And it's also very strange to say, this landslide, collapse and earthquake seem to deliberately can't get along with people, for a while there was a landslide in the old county town of Wulong Yunyang, and there was an earthquake in Zigui Xingshan for a while, and in a few days the new city of Badong was built on the old landslide body and had to be rebuilt in another place, and after a few days there was a huge landslide in the new county town of Yunyang, threatening the safety of tens of thousands of people, and after a few days there was a collapse in Zigui, this time it really killed people.

"Although the idea is good, but the southwest terrain is complex, there are many problems, just thinking about the light is obviously not enough, the previous preparation work is obviously very sufficient, but now it seems that there are still many problems, it can only be said that with the development of the times, our understanding of the environment has improved." Fan Heng said with some interest.

If he just watched from the sidelines, Fan Heng would not have felt so much emotion, but when he was there, he felt how difficult it is to do a little thing.

It's not that many people on the site didn't work diligently, or that the technicians cut corners and neglected their duties, or that the entire building operation was emptied of funds, but that it was difficult to build a flawless dam under the current conditions.

Some problems in the project are not a problem, there is no perfect thing, but if there are problems, we need to find a way to solve them, rather than blindly covering them up.

This dam can be said to carry the wishes of the people of the entire provinces in the middle reaches of the Yangtze River for many years, and everyone hopes that they will not have to suffer from the floods of the Yangtze River in the future, but from the perspective of Fan Heng, it is unrealistic to announce that this goal has been achieved at this time.

The high-level view on this issue is not very optimistic, so this year it still allocated more than 6 billion yuan for the construction and repair of embankments in the provinces along the middle and lower reaches of the Yangtze River, which is enough to explain the problem.

"In any case, our goal has been achieved, and now when we return to the capital, no one can say that we have not fulfilled our responsibilities, that is, what will we say in the future, the photos we took and the specimens we brought back are enough to illustrate the problem." Song Qing saw that Fan Heng was in a bad mood, so she comforted her.

Fan Heng smiled, and then said, "I suddenly remembered what I said to me without disease, life is like a cup of tea, it will not be bitter for a lifetime, but it will always be bitter for a while." There is always a gap between the ideal and the reality, fortunately there is still a gap, otherwise, who is still rare and ideal? ”

Speaking of Fan Wuxi, Song Qing couldn't help but smile and said, "He has said a lot, you have to be grateful to the person who hurt you, because he has tempered your mind; Be grateful to him who deceives you, for he has increased your wisdom; Be grateful to the one who slandered you, for he sharpened your character. Be grateful to the one who whipped you, for he stirred up your fighting spirit; Be grateful to the one who forsaken you, for he taught you to be independent; Be grateful to the one who stumbles over you, for he strengthens your legs; Be grateful to the person who rebuked you because he reminded you of your shortcomings. ”

Fan Heng talked about his son, and his mood was much better, and then said to Song Qing, "Hehe, the matter is over, I will go home tomorrow." On the Politburo side, there must still be a meeting to discuss the matter of my own slip away. ”

There are no pop-ups
