"I want to go up the embankment to see the situation." Fan Heng looked at the scaffolding like in the mist. Said to the entourage.

After hearing Fan Heng’s request, both the entourage and the people in the construction headquarters of the reservoir area were a little panic. Leaders who do not usually have any working experience go to the embankment to check the situation in person, and no one will feel at ease in his heart.

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

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

Fan Heng shook his head and said, "I was entrusted by the Central Committee to investigate this matter. Since I am here, how can I feel at ease if I don't go up and see it?"

When he said that, he ignored what others said, and found a hard hat to put on, and then accompanied by a few bodyguards on the scaffold under construction, and then climbed to the place where the crack appeared on the embankment.

The retaining surface of the dam is close to the heart 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 scaffolds, which are called seam-fixing slots by the migrant workers, were erected, covered with green protective nets, like "green centipedes" erected and attached to the middle and lower parts of the dam.

Directly below these "green centipedes", a construction trench with a length of hundreds of meters and a depth of tens of meters was dug along the edge of the dam body. Workers are busy constructing along the edge of the dam body under the deep trench.

Fan Heng and others climbed up several layers of the seam-fixing groove and saw cracks from top to bottom on the dam wall, the width of which could be inserted into the palm of an adult. After questioning the construction workers, these are all cracks that are currently to be treated. Because of the need to grouting and adding various new materials, they used a portable cutter along the cracks to scrape off the surface waterproof cement layer next to the cracks a few centimeters thick, dozens of centimeters thick. Cm wide, and then cut the seam a little bit to facilitate construction.

At the top of the "green centipede" is a huge middle-level spillway, where a scaffolding platform walkway is built, which is in the middle of the dam, and you can see the strips of the dam cut out from the top along the dam body. Sew. The workers said that those have already been processed.

A construction worker told Fan Heng that the reason for the cracks was that there was a problem with the partition material between each pouring section and the section, and there may also be some problems with the foundation below, but the specific reasons are still needed. The experts discerned.

The dam has been completely closed since the start of construction, and the quality of the dam is unknown to the outside world. This time it was stabbed out, and it was also spread by the Internet first, but it is definitely difficult for ordinary people to distinguish the authenticity. It's all just rumours.

A deputy general manager of the Construction Corporation followed Fan Heng closely and explained to him, “This is just a shallow crack on the surface and will not affect the safety of the dam. Dam cracks, all hydropower projects at home and abroad In the project, it is unavoidable. The occurrence of cracks in large-volume concrete is a problem that is difficult to completely avoid in dam pouring. As the world's largest dam with the largest amount of concrete pouring, it is also difficult to cause cracks in the dam during continuous high-strength construction. Spared."

Another expert who came from Beijing in advance also said, “Unlike ordinary thin-walled structures, the casting temperature of large-volume concrete is very complicated, because it is very large and high, and the concrete is going to be hot. In terms of temperature control, although comprehensive measures have been taken to cool the low-temperature concrete, after all, the maximum temperature of the concrete is relatively high. The minimum temperature of the dam is somewhat lower under the changed conditions. After the temperature difference is caused, the large-volume concrete will inevitably appear to be cracked. So we turn to hydropower Concrete cracks and other repairs during construction are the last process in concrete construction. It is just a process, and it is impossible to finish the dam without any defects."

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

In the feasibility demonstration of the project, the flood control team proposed that the project should achieve the expected flood control goal, and the flood control storage capacity should be at least 25 billion cubic meters. According to the project proposal approved by the National People's Congress, the flood control storage capacity is only 22.1 billion cubic meters, which is already smaller than the flood control group's requirements.

Later, teachers and students of the Department of Water Resources of Tsinghua University recalculated the flood control storage capacity and concluded that the flood control storage 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 storage capacity caused by calculation errors. The threshold of the dam lock is raised.

However, flood control efficiency is an important function of the dam, and it is also the most important project goal of this project. If the flood control efficiency cannot be realized, it is tantamount to admit that this project is a bit disappointing.

The threshold of the dam ship lock needs to be raised, and most of the freight will be interrupted here and rely on mechanical overturning of the dam. The Prime Minister said before his death that the construction of a dam on the Yangtze River would cause the dam to be blown up if shipping on the Yangtze River was interrupted. Although it is unknown whether this is true or false, there is always such a saying. If this problem can be solved, it will be entangled. After all, tens of billions have been spent on the dam, and the investment after the completion of the dam It is even closer to 200 billion. If such a large project is not satisfactory, it is indeed impossible to explain it.

If only considering the issue of electricity, then building a few nuclear power plants is more than adequate. The investment is definitely not that big, and the time, energy, manpower and material resources are definitely not that much.

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

Fan Heng watched carefully on the embankment all morning. At this time, it was sweltering heat and the weather was extremely hot, and the group felt that the heat was too hot. Then he left the embankment. Before leaving, he took a lot of fieldwork pictures on the spot. As a reference, the repair methods and materials provided by the construction headquarters of the reservoir area were registered one by one, and some samples were taken back for future reference.

After returning to the hotel and staying in the hotel, the surrounding local government officials rushed over to cooperate with the guards who had just arrived to implement the safety affairs. 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. When it came time for lunch, he even ordered the hotel to arrange a few banquets to entertain these people. Everyone felt that Vice Premier Fan was very easy to get along with.

During the dinner break, Fan Heng felt a little bit of heat stroke, so she asked Song Qing to take out the heat-repellent medicine that Fan Wuyi had prepared for him to soak in water.

"Preparation for disease-free is very sufficient, all year round. I can always prepare all kinds of medicines that need to be used at home." Song Qing said to Fan Heng.

Fan Heng nodded and said, "No disease knows that I am busy at work. I deliberately prepared a lot of tonic drugs and arranged a rich diet. Over the years, relying on his conditioning, my body has never had any major problems. "

"This time things are very troublesome." Song Qing couldn't help mentioning the crack in the embankment.

When Fan Heng heard this topic, he couldn't help but ponder, and then he said with emotion, "Back then, the National People's Congress passed the resolution to build the Three Gorges Dam on the Yangtze River, and the news came. The people in the reservoir area were excited and set off firecrackers to show. Celebrate. Now that several years have passed, the joy of the people in the reservoir area has long gone with the Yangtze River flowing eastward. Many of them may not be able to say whether they should be happy or worried. When the old workers of Fengjie Cement Plant are wonderful In the first explosion, I saw that the factory I built was instantly wiped out. When the peasant woman in Qu Yuan’s hometown had to cut down the citrus tree that was about to bear fruit, when the immigrants in the ancient town of Dachang waved goodbye to the Wen family compound, which had lived for more than a dozen generations, and went away. Maybe they have a lot of expectations. Not only these ordinary people, but also the decision makers, planners, advocates, supporters or unknown people of this project, there are also many who did not expect it."

When Song Qing heard Fan Heng speak like this, she felt the feeling of helplessness in Fan Heng's words.

In the morning, the deputy general manager said quite frankly that in the past few years, the general direction of the project is good, but there are still some defects and 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 entire project, it is only a small amount in part, but it still has an impact on the progress of the project, and it will have a greater impact this year. Since the emergence is relatively early, the processing is basically relatively timely. If the emergence is to be carried out before the closure of the river, there will be no time for processing.

When Fan Heng asked whether the dam had any damage to its tendons and bones, and whether it was possible to overturn it, the chief engineer said that it is impossible to completely avoid cracks on the dam surface. The question is whether it will cause harm to the dam. These cracks that are now present have recently been appraised by experts and are not hazardous cracks. But if it is not handled properly, it may develop into a hazardous crack. At the same time, he also admitted that in terms of forecasting, he did not expect it to expand so quickly.

Another situation is not optimistic. Only a few years after construction started, there was news that the geological disasters in the reservoir area were serious, including more than 3,000 landslides. More than a thousand collapsed and deformed bodies. According to official media, more than 40 major geological disasters have occurred in this area in the past ten years, and there are still more than 1,500 collapses and landslides.

Among these landslides, nearly a thousand are located below the 135-meter water level at the initial stage of the project. According to a report from the Yangtze River Water Conservancy Commission, there are more than 1,300 areas with hidden geological hazards in the reservoir area, and more than 100 areas need to be dealt with.

After Fan Heng got the information, the first thing he thought of was a problem. The decision makers of the project at the time certainly didn't know these conditions. Otherwise, it would be impossible to make such a decision.

And it’s very strange to say that this landslide, collapse and earthquake seem to be deliberately struggling with people. A landslide occurred in the old town of Yunyang, Wulong, and the earthquake in Zigui Xingshan. A few days later, Badong New City was built on the old landslide. After rebuilding in a different place, a huge landslide appeared in the new county town of Yunyang a few days later, threatening the safety of tens of thousands of people, and a few days later Zigui collapsed, this time it really killed people.

"Although the idea is good, the topography of the southwest is complicated and there are many problems. It is obviously not enough to just think about the light. The previous preparations are obviously sufficient, but now it seems that there are still many problems. With the exhibition of the times, our understanding of the environment has improved again." Fan Heng said with some interest.

If you just watched it from the side, or Fan Heng would not have so much emotion, but when he was on the scene, he realized how hard it is to do something.

This is not to say that many people on this construction site are not working diligently, nor that these technicians cut corners and neglect their duties, nor that all the funds for the entire construction operation have been vacated, but that the current It is indeed difficult to build a perfect dam under conditions.

Some problems in the project are not a problem, there is no perfect thing, but when there is a problem, you need to find a way to solve it, rather than blindly cover it up.

This dam can be said to have carried the wishes of the people in the middle and small reaches of the Yangtze River for many years. Everyone hopes that they will no longer suffer from the floods of the Yangtze River in the future. The goal has been achieved, but it is not realistic.

The high-level views on this issue are not very optimistic, so more than 6 billion has been allocated this year for the construction and repair of dikes in various provinces along the middle and lower reaches of the Yangtze River~www.wuxiamtl.com~ This is enough to explain the problem.

"In any case, our goal has been achieved. Now when we return to the capital, no one can say that we have not fulfilled our responsibilities. What will happen in the future? The photos we took and the specimens we brought back are enough to explain the problem. Seeing that Fan Hyung was in a bad mood, Song Qing said comfortingly.

Fan Heng smiled, and then said, "I suddenly remembered what Wuyi said to me. Life is like a cup of tea. It will not suffer for a lifetime, but it will suffer for a while. There is always a gap between ideals and reality. Fortunately, there is still a gap, otherwise, who would still be ideal?"

Speaking of Fan Wubing, Song Qing couldn’t help but smiled, “He’s said too much. Be grateful to the person who hurt you, because he has tempered your mind; grateful to the person who deceives you, because he improves Thank you for your wisdom; be grateful to the person who slandered you, because he has strengthened your personality; be grateful to the person who beats you, because he inspires your fighting spirit; be grateful to the person who abandoned you, because he taught you that you should be independent; Be grateful to the person who tripped you, because he strengthened your legs; be grateful to the person who scolded you, because he reminded you of your shortcomings."

When Fan Heng talked about his son, he felt much better, and then said to Song Qing, "Hehe, the matter is over, I will go home tomorrow. At the Politburo, I must still have a meeting to discuss the matter of my slipping away. "
