【233】The five major reservoirs created the Pishihang Irrigation District

After listening to Xiaoqiang's words, Qian Zhengying no longer had any doubts. He spoke so professionally, and he had clearly explained the key points in the newly released "Water Conservancy Engineering Reinforcement".

Qian Zhengying said: "We are doing it in this way now. Before we didn't have a vibrating machine, we relied on migrant workers to build the dam with soil, and then the migrant workers' team used stones to compact the loose soil. The efficiency is really low. Now we have enough reinforced concrete and construction machinery, and even vibrating machines and cement piles, I feel completely confident that this year’s flood season predicted by the central government will be once in ten years. But I have a question, why don’t we The scheme design of the water conservancy project is used to build the Runheji Dam? Why did you choose the design scheme of Wangjiaba? Since the experts chose the Wangjiaba scheme, why did they have to spend a lot of effort to ask the Soviet experts to design a Runheji Dam scheme? Woolen cloth?"

Xiao Qiangxin said, in order to let you see clearly, so as not to make a mistake in repairing the Runhe diversion sluice, I also bought this plan from the National Engineering Database, which was selected by Soviet experts in history.However, the main design of the Runheji Dam project designed by the Soviet experts was problematic, and the final consequences were very serious. When the Huaihe River flooded in 1954, the 1950-year flood in the Huaihe River, which was more severe than the once-in-10-year flood in 40, completely broke down the dams in Runheji, causing the Huaihe River to burst. More than 2000 people died!The Soviet expert's Runheji dam plan was simply a hasty project, too big and unreasonable. Only the water diversion and flood discharge sluice project has some value.

The lesson that this Runheji dam project has brought to New China is painful.Without several years of serious research, it was only something that Soviet experts came to inspect two or three months later. For New China, it was a painful lesson of superstitious "foreign crutches".The most taboo thing about water conservancy projects is the wrong site selection of the dam. If the site selection is wrong, can there be good results?In the end, New China settled on its own Wangjiaba plan after several years of hard work and solid research by soil experts.It is small in scale but eventually known as the first gate of the Huaihe River. Not only can it block and store floods, but it has also been opened 15 times in history to release floodwater into the flood storage area, successfully achieving the original design intention of preventing floods.

Xiaoqiang fooled: "I think there is a problem with the plan of the Soviet experts. Compared with Wangjiaba, Runheji is too downstream. The dam cannot withstand the impact of a severe flood at all, and the project volume is too large. In my opinion, the Huaihe River The river basin may have a larger-scale flood in 1954 years in 40. By then, the inherently deficient Runheji Dam will have become a failed design and is likely to collapse. Therefore, the expert group finally decided to Wangjiaba, which is further upstream, will build a small dam and a water diversion and flood discharge sluice. For the sake of insurance, a water diversion and flood discharge sluice will be added in Runheji, but another dam will not be built in Runheji. We can learn from the design of foreign experts , but we must never rely on "foreign crutches", if we do not lose the psychological "foreign crutches", we will not be able to walk out of the road of self-reliance and independence."

After hearing this, Qian Zhengying looked at Xiaoqiang even more eagerly and said, "These experts of the 491 Project are really amazing! This kind of comprehensive dam blueprint, which can only be designed after several years of research, was completed when the Huaihe River Control Committee was established. You can still analyze the disadvantages of the Soviet plan by looking at the drawings. Comrade Xiaoqiang, you must convey the respect of all our engineers on my behalf, thank you!"

Cao Xiaoqiang agreed cheekily: "Although the plan is good, it can only be done if it is implemented. After this year's flood season is over, the comprehensive management of the Huaihe River Basin will really start."

Qian Zhengying asked: "I don't know what other projects the central government has planned?"

Xiaoqiang said according to the information compiled by the 491 Project: "Compared with the dry season in the flood season of the Huaihe River, the increase in water volume is very large. Just add a floodgate to the dam and it will be done.

After the flood season, we will start from the upper reaches of the Huaihe River. We will build the Foziling Reservoir, Meishan Reservoir, Mozitan Reservoir, Xianghongdian Reservoir, and Longhekou Reservoir. These five key reservoirs will manage the Huaihe River from the source. Contain the flood from the upstream Dabie Mountains from the source.Once these five key reservoirs are built, the Huaihe River will be under our control from the source.

After the Foziling Reservoir is completed, the annual power generation capacity will be 9350 million kWh. After the Meishan Reservoir is completed, the annual power generation capacity will reach 1.6 million kWh. The Mozitan Reservoir will generate 5800 million kWh. 1.5 million kilowatt-hours, the Longhekou Reservoir generates about 1000 million kilowatt-hours, and the combined power generation of the five reservoirs is 4.7 million kilowatt-hours.From the perspective of flood control alone, the Foziling Reservoir is the most important, and it can be said to be the first dam of the Huaihe River. "

Vice-Premier Dong said in surprise: "Now the country's annual power generation is only 43 billion kilowatt-hours, but these three reservoirs can generate 4.7 million kilowatt-hours! It's more than [-]% of the total power generation of the country last year?"

Xiaoqiang nodded and continued: "Cooperating with these five major reservoir projects, a series of supporting small reservoirs and flood gate diversion channels will be built in other tributaries of the upper and middle reaches of the Huaihe River to prevent disasters during the flood season and to irrigate in normal times. I have a picture here for everyone to see one time."

As he said that, Xiaoqiang took out a map of the distribution of water conservancy projects in later generations with clearly marked water systems, and handed it to Qian Zhengying.

Qian Zhengying became more and more surprised as he watched, and said: "The experts from the central government have actually completed the survey, and all the site selections have been completed? This...how is it possible!"

Xiaoqiang smiled and thought full of admiration, this is the final result of you water conservancy workers in New China carrying dry food and walking sticks in your hands, and measuring the entire river basin inch by inch with iron feet. I just return the results of your decades of work in advance. That's all for you.

Especially for these five reservoirs, after the completion of the construction, New China will have an additional "Pishihang Irrigation District", adding 1000 million mu of irrigated farmland to China.

Inspired by the chairman's inscription "We must repair the Huaihe River"!The people of Anhui burst out with the greatest enthusiasm and wanted to present a gift to the great leader.

Anhui, nicknamed the hometown of beggars, Zeng Xisheng, the first secretary of the Anhui Provincial Party Committee, known as the "beggar leader", led the military and civilian mobilization of Anhui to 4 million working days!Under the conditions of economic difficulties, lack of materials, backward technical equipment, and no construction machinery, they used picks and wheelbarrows to carry them on their shoulders and hands, and excavated 1.5 million cubic meters of earth and stone.You know, the total excavation volume of the Three Gorges Project plus the total amount of concrete used in later generations is only [-] million cubic meters, but the Chinese people led by the chairman actually completed the four Three Gorges Projects purely by hand!This is the power gained by relying on the people, and it is also the power that can only be mobilized by a party that is completely rooted in the people.From today's perspective, this kind of miracle is simply impossible to replicate!

After the completion of the Pishihang Irrigation District, more than 30 countries from the United Kingdom, the United States and France came to observe it. It is very simple because they don't believe it...but the facts are in front of them.Among them, the Longhekou Dam is a sand shell dam with a clay core wall, which was built entirely by earth methods, and was finally honored by UNESCO as the world's largest artificial dam.
