Thank you for the reward!

[233] The five major reservoirs created the Weishi Hangzhou Irrigation District

After listening to Xiaoqiang's words, Qian Zhengying no longer doubted that he had said it so professionally that he had clearly explained the key points in the newly issued book "Water Conservancy Project Reinforcement".

Qian Zhengying said: "We are now doing this way, in the past, we did not have a vibroflotation machine, all rely on migrant workers to use earth to mop the dam, and then the migrant workers use stones to tamp the scattered soil, the efficiency is really low." Now that we have enough reinforced concrete and construction machinery, and even vibroflotation machines and cement reinforced piles, I feel that we are completely sure that we will survive the once-in-a-decade flood season predicted by the central government. However, I have a question, weishenme, don't we build the Runheji dam according to the design of this Runhe water conservancy project? Weishenme should choose the design scheme of Wangjiaba? Since the experts chose the Wangjiaba scheme, Weishenme still has to spend a lot of effort to get the Soviet experts to design a scheme for the Runheji dam? ”

Xiao Qiangxin said, in order to let you understand and not repair the Runhe collection and distribution sluice by mistake, I specially bought this plan of the Soviet experts selected in history from the national engineering database. However, the main design of the Runheji Dam project designed by Soviet experts was problematic, and the final consequences were very serious. In 1954, when the Huai River basin flooded, the 40-year flood of the Huai River basin, which was more violent than the 10-year flood in 1950, completely washed away the dam of Runheji, and the Huai River burst its embankment, killing more than 2,000 people! The Soviet expert's plan for the Runheji dam was nothing short of a rush, and only the project of the flood gate was still of some value.

The Runheji dam project has taught New China a painful lesson. After several years of serious investigation, it was only the Soviet experts who came to inspect what they came up with two or three months later, and it was a painful lesson for the new China that was completely superstitious about "foreign crutches." The most taboo in water conservancy projects is that the dam is located in the wrong location, and the site is selected wrong, can there be good results? In the end, under the hard and down-to-earth research of soil experts for several years, New China decided on its own Wangjiaba plan. The small scale but eventually known as the first gate of the Huai River, not only can block the flood storage, but also open the gate 15 times in history to release water into the flood storage area, successfully achieved the original design intention of preventing floods.

Xiaoqiang fooled: "I think there is something wrong with the plan of the Soviet experts. Compared with Wangjiaba, Runheji is a little too downstream, and the dam cannot withstand the impact of the catastrophic flood, and the amount of work is too large. In my opinion, there may be a larger, once-in-40-year flood in the Huaihe River basin in 1954, and then the congenitally inadequate Runheji dam will become a failed design and will probably collapse. Therefore, the expert group finally decided to build a small dam and a diversion flood gate in Wangjiaba, further upstream, and to add a diversion flood gate in Runheji at the same time for the sake of safety, but not to build another dam in Runheji. We can learn from the designs of foreign experts, but we must not rely on "foreign crutches", because if we do not throw away the psychological "foreign crutches", we will not be able to walk out of the road of self-reliance and independence. ”

After listening to this, Qian Zhengying looked at Xiaoqiang more eagerly and said: "These experts of the 491 project are really amazing! This kind of comprehensive dam drawings, which can only be designed after several years of research, have been done as soon as the committee has been established, and they can analyze the shortcomings of the Soviet plan by looking at the drawings. Comrade Xiaoqiang, you must convey the respect of all our engineers on my behalf, xiexie you! ”

Cao Xiaoqiang cheekily agreed: "Although Jihua is good, it can only be implemented, and when the flood season is over this year, the comprehensive management of the Huaihe River Basin will really begin." ”

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

Xiaoqiang said according to the information compiled by the 491 project: "Compared with the flood season and the dry season of the Huai River, the increase in water volume is very large, which is imagined by Soviet experts from the alpine region of the extreme north, so it cannot be done with a dam and a flood gate as imagined by Soviet experts."

After the flood season, we should start to rectify the tributaries in the upper reaches of the Huai He, and build five key reservoirs, namely, the Foziling Reservoir, the Meishan Reservoir, the Mozitan Reservoir, the Xianghongdian Reservoir, and the Longhekou Reservoir, to manage the Huai He from the source and to enclose and store the floodwaters in the Dabie Mountains in the upper reaches of the river from the source. Once these five key reservoirs are completed, the Huai River will be controlled by us from the source.

This Foziling Reservoir has an annual power generation of 93.5 million kWh after it is completed, Meishan Reservoir has a power generation of 160 million kWh a year, Mozitan Reservoir has a power generation of 58 million kWh, Xianghongdian Reservoir can generate 150 million kWh, Longhekou Reservoir has a power generation of about 10 million kWh, and the power generation of the five reservoirs together has 470 million kWh. From the perspective of flood control alone, the Foziling Reservoir is the most important, which can be described as the first dam of the Huai River. ”

Vice Premier Dong was surprised: "Now the annual power generation of the whole country is only 4.3 billion kilowatt-hours of electricity, and these three reservoirs can generate 470 million kilowatt-hours of electricity!" Can it be more than 10% of the country's total power generation last year? ”

Xiao Qiang nodded and continued: "In cooperation with these five major reservoir projects, other tributaries in the middle and upper reaches of the Huai River will also build a series of supporting small reservoirs and flood gate diversion canals, and irrigate them during the flood season. I have a picture here that I can show you. ”

As he spoke, Xiaoqiang took out a map of the distribution of water conservancy projects in later generations with clear water system labels and handed it to Qian Zhengying.

The more Qian Zhengying looked at it, the more surprised he became, and said: "The experts of the central government have already completed the survey, and all the site selections have been completed?" This...... Here's how to get there! ”

Xiao Qiang smiled and thought with admiration, this is the final result of you new China water conservancy workers holding crutches with dry food and measuring the whole river basin inch by inch with iron feet, I just returned the results of your decades of work to you in advance.

In particular, after the completion of the construction of these five major reservoirs, New China will have an additional "Weishi Hangzhou Irrigation Area", adding 10 million acres of irrigated fertile land to China.

Inspired by the inscription of the chairman "must repair the Huai River"! The people of Anhui burst out with the greatest enthusiasm and wanted to present gifts to the great leader.

In Anhui, which is nicknamed the hometown of beggars, Zeng Xisheng, the first secretary of the Anhui Provincial Party Committee, who is known as the "beggar leader", led the general mobilization of the military and civilians in Anhui to 400 million working days! Under the conditions of economic difficulties, lack of materials, backward equipment, and no construction machinery, 600 million cubic meters of earth and stone were excavated with pickaxes and wheelbarrows. You must know that the total amount of earth and stone excavated in the Three Gorges Project and the total amount of concrete used in later generations were only 150 million cubic meters, but the Chinese people led by the chairman actually completed four Three Gorges projects purely by hand! This is the liliang obtained by relying on the people, and it is also the liliang that can only be mobilized by a party that is completely rooted in the people. In today's view, such a miracle is simply impossible to replicate!

After the construction of this Hangzhou irrigation area, more than 30 countries in the United Kingdom, the United States and France came to observe, and it was very simple, because I didn't believe it...... But the facts are in front of us. Among them, the Longhekou Dam is a clay core wall sand shell dam, which is completely built by earth method, and Zuihou is praised by UNESCO as the largest artificial dam on Shijie.
