Summary of Wenhe Wenhe Irrigation District

Wenhe Irrigation District in the suburb of Yangquan City is located in the northern suburb, 25 kilometers away from the urban area. It is a small-scale (1) water control project integrating diversion, storage and lifting. The project started in 197 1 year1month and was completed in 198 1 year in October. The main project consists of Youweng Reservoir, Liangchahe High Irrigation Station, main canal and branch canal.

Wenhe River originates from Fangshan in Yuxian County, and is formed by the confluence of seven rivers, including Wuyu River, Xiushui River, Xianghe River, Shidian River, Yinshan River and Charlotte River. Its main stream flows into our region from Nanliu Village and into Pingding County in Xinzhuang. It joins Taohe River in Niangziguan, Pingding County, called Mianhe River, and flows into Hutuo River in Hebei Province. It belongs to Ziya River system in Haihe River basin and belongs to seasonal river. The basin above the dam of Youweng Reservoir covers an area of 600 square kilometers, which belongs to an area without hydrological data, but there are a lot of precipitation data. Therefore, the annual runoff in this area is calculated by using the local annual precipitation data and the annual precipitation-runoff relationship in similar areas.

Through analysis and calculation, the average annual runoff for many years is 22.28 million cubic meters, and the sediment transport model of the control basin is 2372t/ km2. The average annual sediment discharge for many years is140,000 tons.

Youweng Reservoir is located on the main channel of Wenhe River, with an effective storage capacity of 80,000 cubic meters and a controlled drainage area of 600 square kilometers. The dam type is a masonry gravity dam with a bottom elevation of 803.00 m, a top elevation of 82 1.75 m and a top elevation of 60m. The reservoir design standard is once every 50 years, and the check standard is once every 0/00 years.

Liangchahe High Irrigation Station is located about 500m downstream of Youweng Reservoir. The pumping station room is divided into basic machine room, and two 12SH-6 pumps are arranged in a row. The designed pump flow is 760m3/ton, the supporting motor is 300kw, the medium 400 pressure cast iron pipeline is laid 500m, and the total lift is 86.7m..

There are three main canals in Wenhe Irrigation District, of which the main canal from Wenchi Diversion Dam in Yuxian County to the diversion sluice is 9.02km long, with a designed storage capacity of 3m3/s; Nanqianqu, from sluice to suburban water supply company, has a total length of l 7.87km and a design flow of 2 cubic meters per second. The north main canal is 7.59km from the diversion sluice to Longjiang Pool in xinan town, with a designed water conveyance capacity of 1 m3/s. There are 1 l branches with a total length of 27.44km.

The total investment of the project is 8 million yuan, the total construction period is 10 year, the number of workers is10.5 million (excluding the voluntary labor of the masses), and the total engineering quantity is 706,000 cubic meters.

Wenhe Irrigation District is a key water conservancy project built in the suburbs in the 1970s, and it is a fruitful achievement of self-reliance and hard struggle of the people in the whole region. After the completion of the irrigation area, the production and living water of 76 villages, 654.38+ 03 enterprises and 654.38+02 mu of farmland in the northern suburbs were solved, which played an important role in the development of industrial and agricultural production and the improvement of people's living standards in the suburbs.

As Wenhe Water Conservancy Project was a tripartite project of "design, construction and benefit" during the Cultural Revolution, its sequela was gradually exposed after the project was put into operation. In addition, after years of operation, the engineering facilities were aging and disrepair, and were repaired twice in 1988 and 200 1. The maintenance and renovation of 1988 started in August of that year and was completed in June of 1989, which lasted for 15 months with a total investment of 2.08 million yuan. Maintenance channel 1 1.89km, update 10kw high-voltage transmission line 606km, and two groups of pumps; Add and update communication line 38.7 1km. 200 1 maintenance and renovation started at +0 () in June 2000, and was completed at1+0/in June 200 6, lasting 13 months, with a total investment of 4,445,700 yuan. The reconstruction of U-shaped concrete channel was completed for 20.48 kilometers, and the tunnel base and local collapse were treated. After the renovation of the irrigation area, the water utilization rate of the canal system reached 80%, and the effective irrigation area expanded to 20,000 mu. The suburban Wenhe Water Conservancy Project, an "artificial Tianhe" coiled on a steep cliff, is the crystallization of the wisdom and strength of the broad masses of the people.

Wenhe water conservancy project is the largest project in farmland water conservancy capital construction since the liberation of our city. Including main canals and branch canals with a total length of 120, aqueducts with a total length of 1000 meters, 54 tunnels with a total length of more than 20, inverted siphon 19 and 3 reservoirs with a storage capacity of more than 3 million cubic meters. After the completion of all the projects, eight communes in the suburbs will benefit. In addition to meeting the water demand of people and livestock, 50,000 mu of land can be irrigated.

The Wenhe River, which originated from Fangshan in Yuxian County, is the largest river in the northern suburb of our city. In the evil old society, people on both sides of the Wenhe River can only watch the Wenhe River flowing at their feet, but the mountains are "barren hills and bare mountains, and the water is as expensive as oil, planting crops every year and failing to harvest every year". An old man who was over 60 years old in Huoshiyan Brigade of Sanjiao Commune told us about the miserable life of poor and middle peasants before liberation: 1920, Huoshiyan didn't drop a drop of rain for 890 consecutive days, the water cellar dried up and the river dried up. People are struggling on the death line of drought. Every day before dawn, people pick up buckets and climb mountains to find water eight, ten or even fifteen miles away. It takes half a day to carry a load of water. Draught water is so difficult, where did you get the irrigated land? The cruel exploitation and oppression of the landlord class and the threat of drought forced poor farmers to sell their children and leave their homes. At that time, there were only 70 or 80 people in Huoshiyan village, 36 people starved to death and fled, and more than 20 families were forced to sell their own flesh and blood. At that time, people circulated such a ballad: "The warm river bends, and the people on both sides of the strait are really tired; The landlord was forced to rent debts, and it was harder to eat water than oil. The poor have no way to live, and selling children and selling women is broken. "This is a true portrayal of people's lives at that time!

For many years, people on both sides of the Wenhe River have been looking forward to one day "Qinglong" going up the mountain to solve the draught of people and animals and irrigate ten thousand mu of fertile land. There is an old poor peasant named Zhao Hulai in Han Zhuang Brigade, who is over 60 years old. In the old society, I herded sheep for the landlord for half my life, and I have been running around on both sides of the Wenhe River. He always thinks that on that day, the warm river will be taken up the mountain and the crops will no longer be at the mercy of drought? Every day when he was herding sheep, he let them eat grass, and he sat watching Wen He and used his head. Finally, he thought of a way: measure a water diversion line, poke through the bottom with porcelain pots burned by Petunia Town, cover them one by one, and lead the water back to Han Zhuang. He came to Yuxian Wenchi with dry food on his back, made a level with a sheep whip, measured it back to Han Zhuang with a whip and a whip, and measured a temperature-inducing canal line. He has no education and doesn't understand the drawing principle. He only drew a temperature sensing circuit diagram with patterns he can understand. This is not a simple blueprint for water conservancy, but it is entrusted with the strong expectations of suburban120 thousand people for water!

After the people's commune, the people in the suburbs made plans and reports many times to draw warm river water to irrigate the land. However, due to the interference and influence of the counter-revolutionary revisionist line and the idea of equality, dependence and importance at that time, the project has never been launched and the situation of water shortage has never changed.

1970 After the Northern Peasant Association, the masses in the suburbs once again asked the district committee to bring warm water to water the land. Such a big project needs investment, technology and materials. Can we do it ourselves? Most comrades believe that self-reliance and hard struggle are the teachings of Chairman Mao and the spirit of Da Zhai. If we follow this policy, there will be no insurmountable difficulties, and there will be no Yamakaji. The construction of Wenhe Water Conservancy Project can't wait, rely on and need. We must work hard on our own. The district committee earnestly studied Chairman Mao's teaching that water conservancy is the lifeblood of agriculture, severely criticized the counter-revolutionary revisionist route of "government-run water conservancy", unanimously passed a resolution, and put forward "a set of precious books and two hands to draw a new map by self-reliance. Introduce warm river water, irrigate 100,000 mu of land, strive for three to five years, and turn the suburbs into Jiangnan ",relying on the people in the whole region to complete the warm river water conservancy project.

The suburban Party committee established the Wenhe Water Conservancy Project Headquarters. Liu Shuhuan, former party secretary and deputy director of the Revolutionary Committee, personally led the designers of Wenhe Water Conservancy Project to climb mountains and wade, and conducted a comprehensive and serious investigation. After more than a month's efforts, the preliminary design scheme of Wenhe Project has been worked out.

197 1 year1kloc-0/month, the Wenhe Water Conservancy Project is about to start. News, such as spring thunder, resounded through the sky, shaking the rushing warm current; The news is like a horn, inspiring us to take part in this great battle.

Letters of determination and invitations to party committees at all levels, full of revolutionary pride, flew like snowflakes. There is a poor old farmer named Li in Liugou Brigade of the commune, who is nearly sixty years old. Hearing that the Wenhe River project was to be built, he repaired the shovel overnight, made up the basket and prepared to go to the construction site. He heard that the brigade sent his son to the construction site, so he found the brigade cadre and said, "It is my wish for many years to bring the warm current back to the suburbs. I am almost 60 years old now. I have worked hard for decades and I have not done it on the construction site. I will die peacefully. "

When I first arrived at the construction site, it was a lot of difficulties. Without housing, 300 officers and men of Southwest Fen Commune Company were crowded into a village with only 80 people.

Water conservancy projects need a lot of stones. Pilots use local materials and climb mountains tens of meters high to get stones. At first, one shot can hit several stones, which is far from meeting the engineering needs. Liang Yusuo, the company commander of Li Jiazhuang Commune, dared to think and do it, and adopted a bold blasting method. He dug a cave more than ten meters deep halfway up the mountain, which contained 700 kilograms of explosives and smashed a thousand cubic meters of stones with one shot.

Throughout the construction site of Wenhe Water Conservancy, there are sparks of mass wisdom everywhere. There are all kinds of earth hoists, earth cranes and overhead conveyor lines that improve work efficiency several times or even dozens of times than manual operation; There are simple and labor-saving blasting and drilling methods created by the masses themselves. However, what best embodies the wisdom of the masses is the aqueduct flying overhead on the main canal.

The No.2 aqueduct of the main canal built by Southwest Fen Commune Company is 70 meters long and 30 meters high. It has a double-arch reinforced concrete structure and a single hole with a clear span of 24 meters. Building such a water pipeline is not an easy task. What should I do if I want to hang a girder weighing five or six tons into the air of more than ten floors and combine it with the designed dragon? Comrade Guo Zhongxiu, the head of the engineering headquarters, went deep into the masses and held many "Zhuge Liang" meetings to mobilize the masses to find ways. He carefully considered opinions and suggestions from all sides. Finally, it is decided to adopt wire rope hoisting method. They first got off two ground anchors, hoisted two steel ropes to more than ten floors, and made several sets of pulleys for hoisting. However, due to the complex terrain, there is no flat place on both sides of the river, and the girder is heavy, the anchor hoisted for the first time was pulled out. They are not discouraged, not discouraged, seriously sum up the reasons for this failure, fight for two days, repair the ground anchor and carry out the second hoisting. This time, they adopted the method of combining high-altitude pulley hoisting with grinding machine and stable car hoisting. When there is electricity, they use electricity to lift it, and when there is no electricity, they mobilize the masses to lift it manually. Finally, the four girders were successfully placed on the pier. A modern reinforced concrete double-arch aqueduct spans a deep mountain canyon.

Yuxian, where Wenjiang passes, is a towering mountain. Walking on the narrow path halfway up the mountain is really scary. Looking up, I saw a blue sky; Looking down, it is an abyss. But who ever knew that in this high mountain, the temperature-inducing soldiers had a tenacious struggle with the rocks in order to get through the tunnel!

The No.1 hole passed by the main canal is a famous and important project of the whole canal, with a total length of more than 270 meters. Its difficulty lies not only in the length, but also in the fact that the geological structure is full of Benxi strata, which is very difficult to fight. The vast number of officers and men of Yin Ying Corporation, which undertakes the construction task here, are not intimidated by difficulties. Under the leadership of company commander Shi Liting, they studied Chairman Mao's great teaching, "I agree with this slogan and call it' I am not afraid of suffering, and I am not afraid of death'", and firmly said: "Shi Hu is not as hard as our bones, and we dare to touch it!" They beat the rocks with hammers and drills. Zhang Bianying, a young woman, started to hit only a dozen centimeters a day. When others finished their work, she aimed at a fixed point on the stone and continued to insist. It only took four or five days to learn hammer drill, and now she can hit three or four hundred strokes in a row. Shi Aiying, a young woman, can catch two brazing rods by herself. On one occasion, a sledgehammer hit her hand, and blood flowed, but she gritted her teeth and couldn't get out of the line of fire. In front of these brave soldiers, Shi Hu finally lost the battle. After the tunnel entered several meters, new difficulties came again. After the rocks in Benxi were blown away by the wind, they quickly weathered, causing serious landslides, reaching more than 100 at a time. The shower water also fell like a light rain. When describing the scene in the cave, Wen Youbing said: "Look around the cave, drop bombs everywhere, choose a good foothold, and race against time." Although the landslide was serious and there were heavy showers, the commanders and soldiers did not take the difficulties to heart. They organized a commando team of more than 20 people, set up tents and piled up bricks. Shower water poured down from everyone's head, and there was no dry place all over, but everyone didn't complain or get tired, so they wrung out their clothes and went on working. In this way, within two months, they managed to get through the cave of 120 meters with good quality and quantity.

At the northern end of a series of dangerous peaks, it is a famous dangerous work area of the whole canal. The mountain is a cliff surrounded by white clouds, and it is a warm current that runs day and night. How difficult it is to split a passage with a width of four or five meters, a height of one meter and a length of six hundred meters on this hundred-meter-high mountainside!

Danger sharpens heroes, and heroes conquer danger. Ren Genyin, deputy company commander of Hedi Commune Company, said: "Difficulties are before us, and there are no difficulties before us. The harder it is for Ren Yangcheng in Linxian County to learn, the more he moves forward. " He has a big rope tied around his waist and a hammer and steel drill in his hand. He climbed halfway up the mountain, stopped working, made holes, shot guns and collapsed mountains. It was the middle of winter and it was freezing. The biting northwest wind rolled sand on his face, which hurt like a needle, and his hands were bloody, but he had to work 14 hours every day, hitting stones in all directions. "Cadres dare to go to the sea, and the masses dare to catch dragons." The next day, more than 20 young people followed Ren Genyin's practice, tied ropes and climbed halfway up the mountain to make holes and shoot. Within two months, they opened a 600-meter-long canal in the mountains.

"Decorate this mountain, it looks better today." After more than four years of hard work by cadres and the masses, more than 250,000 pieces of earth and stone were moved, and more than 40 miles of sewers, 4/kloc-0 tunnels, 4 aqueducts, a million-ton reservoir and 6 inverted siphons were completed. A beautiful grand plan of "all channels turn around the mountains, reservoirs reflect the blue sky, high irrigation stations build ditches, and the suburbs become smaller in the south of the Yangtze River" will soon be presented to people. At present, inspired by Chairman Mao's two poems, New Year's Day editorials in two central newspapers and the spirit of the National Dazhai Conference on Agricultural Sciences, the vast number of commanders and soldiers in the Wenhe water conservancy construction site are riding the east wind, making every effort to prepare enough stones and dig tunnels, striving to achieve ice water removal in March and Dazhai District in three years, and turning the suburbs into a thriving society with the heroic spirit of "catching the moon in nine days".
