once the sting is over, the spring scenery can't stop, and people can't calm down. They always want to jump into nature. It happened that my wife had a primary school classmate who hadn't seen each other for decades in Lu 'an, and this classmate happened to know a teacher's college classmate of his wife, so they made an appointment to go around the mountainous area of Lu 'an, where the classmates met and took pictures of the mountains and rivers, killing two birds with one stone.
My wife and they agreed to meet in front of Lu 'an Chinese Medicine Hospital. Before our car arrived, her classmates suddenly saw a sign saying "No parking offenders taking pictures" and drove into the hospital in a roundabout way. When I came out, I saw that my wife and her two classmates were already talking and laughing together. Then everyone got on the bus and went to Sujiabu.
my wife's two classmates are a man and a woman. The woman's name is Xia Haiyan, who is one year older than her wife. Her father is a soldier, and she is at home all over the world. Xia Haiyan also moves around with her. In 1971, her father came to Hefei to support Zuo, and his family settled in the small garden of Changjiang Road. Xia Haiyan also transferred from Nanjing to his wife's first primary school. At that time, my wife's family was in the courtyard of the Provincial Science and Technology Commission in the east of Changjiang Road Bridge. It was very good for them to go to school and go to school together, and also to play at home with each other. Two years later, Xia Fu transferred to Taizhou, Zhejiang Province, and Xia Haiyan transferred to another school. Since then, the two have never met again. Recently, I wandered around the classmates in the WeChat circle, and the two of them unexpectedly connected their heads.
It turns out that Xia Haiyan's father moved to Lu 'an when he graduated from high school, and his natural home also settled in Lu 'an. In the college entrance examination, in order to avoid being too far away from home, the old comrade-in-arms of his wife's father came forward and admitted his wife to Lu 'an Teachers College. But my wife and Xia lived in the same city for two whole years, and they were unaware of each other. Maybe they met in the street but they didn't know each other. Regarding their friendship, my wife wrote a beautiful article "Growing Small" a few days ago. If you are interested, you can go and have a look.
The male student's name is Zhang Ming, and he is a photo friend with Xia Haiyan. He is very familiar with the photo group. When my wife interacted with Xia Haiyan's WeChat, she learned about this relationship and made an appointment for two people to travel together. Zhang Ming, a middle school teacher, has made great achievements in teaching, good photography and excellent articles. But the child is ill, and for decades, their main energy has been on the child. Fortunately, the situation is stable now, and family life is full of interest. Flowers, birds, insects, fish and tidbits of life have become the subjects of Mr. Zhang's photography and literary protagonists, and the family of three is happy.
I am a driver and escort on this trip. My wife and I agreed on the general direction of going to Sujiabu Old Street, and I will arrange the specific itinerary. I did a little homework before I left, knowing that there is a Hengpaitou water control project near Sujiabu. I have always been interested in the Pishihang project, so I decided to go to Hengpaitou first, then to Sujiabu, and then go home.
Hengpaitou is the name of a village in Sujiabu Town, Lu 'an City. It was originally penniless. Because of the Shi-Hang Project, Hengpaitou became famous all over the world. Sixty years ago, on August 19th, 1958, Pishihang Project broke ground in Hengpaitou Village and was fully completed in 1972. The hub project consists of five parts: intake sluice, scouring sluice, overflow sluice, earth dam and ship lock. It can retain and regulate the discharge water from Mozitan, Foziling and Xianghongdian reservoirs and the water from the upper section of Hengpaitou dam, and introduce it into the main canal of Pi River, with a designed irrigation area of more than 6.6 million mu. The main canal starts from the head of Hengpaitou canal in the west, ends at the end of Xinminba canal in Gaoliu town of Feixi county in the east, and is connected with Wadong and Chuhe main canals, with a total length of 14.5 kilometers. It was opened to water in 1959 and fully reached the standard in 1987. I won't talk about the enormity and difficulty of the project here. Anyway, Dongpu Reservoir in Hefei is enjoying the grace from Dabie Mountain.
briefly talk about Pei Shihang. Shihang River is the three rivers in western Anhui, all of which originate in Dabie Mountain. From north to south, Shihe River, Shihe River and Hangbu River are in turn. Shihe River flows into Huai River, and Hangshui River flows into the nest and injects into the river. Since ancient times, there have been ten years and nine disasters in western Anhui, and the people in Dabie Mountain are in dire straits. In the early days of liberation, four reservoirs, Foziling, Xianghongdian, Mozitan and Meishan, were quickly built in Daxing Water Conservancy in Anhui Province, which played an important role in flood control and flood control. However, Ceng Xisheng, then the first secretary of the provincial party committee, was not satisfied. He wanted to build another large reservoir below the intersection of the East-West Pi River, that is, the horizontal row head, to lead the landscape to the middle of Anhui and supply Hefei, and to form a vast irrigation area to change the agricultural dilemma of Anhui in one fell swoop. However, this idea is too costly and extremely difficult to submerge Huoshan County. Therefore, Lu 'an put forward a compromise method to build the Longhekou Reservoir and then communicate with several major reservoirs to adjust the water storage capacity. Later, after several repetitions, the Pishihang irrigation scheme was formed. At first, the scheme was named Shihai Hang in the order of rivers, and Zeng Xisheng decided to change it to Shihai Hang according to the engineering quantity.
Looking at this super project, it is necessary to build a canal head hub under several major reservoirs, excavate the main canal, and then form a "long vine and melon" irrigation system through branch canals, reservoirs and ponds, so that more than 8% of the farmland in the irrigation area can realize self-flow irrigation. Now, this goal has been achieved. The key projects such as Hongshizui at the head of Shihe Canal, Hengpaitou at the head of Pi River Canal and Longhekou Reservoir at the head of Hangbu River Canal have been completed one after another. The main, main and branch canals have been built one after another, which not only connects the three major water systems in Shihe and Hangzhou, but also spans the two major river basins in Jianghuai, irrigating tens of millions of mu of farmland, ensuring the water supply for production and life of millions of people, and realizing the scientific utilization and large-scale rainwater resources. I think, as far as Anhui water conservancy is concerned, Ceng Xisheng is indeed far-sighted and has made great contributions.
We came out from Lu 'an City and went south along the main canal of Pi River, crossed the main canal at Hengpaitou Village Bridge and entered the scenic spot. I first drove the hub up and down for a week, overlooking Fengyuan Lake (a reservoir blocked by a dam) at Longwang Temple, and visited Xu Xiangqian Statue, Sujiabu Campaign Memorial Hall and Qingyuan Building, before parking in front of the management office building, and everyone went down to have free activities.
It's the dry season in early spring. Under the 1-meter dam (61-meter retaining dam and 5-meter overflow dam), the riverbed is exposed, the plants are not turning green, and everything is yellow and white. It is said that in June and July, the water here is full of grass and fertilizer, herons and birds are flying, the sky is blue and the land is green, and it is full of vitality. Today, although the grass is not green and the birds are not flying, the sky is blue. We leisurely took many photos and got on the bus to Sujiabu for dinner.
cross hengpaitou village, and Sujiabu is 4 kilometers ahead. When I was looking for a restaurant on the street, I saw a street sign indicating that it was 4 kilometers away from Jiugongzhai Scenic Area, so I proposed to go to Jiugongzhai and come back for dinner. But the car ran for 1 kilometers to get to the place. I thought it was a scenic spot like a manor, but I didn't expect it to be a mountain. The village under the mountain was called Jiugongchong Village, Shibanchong Township. Since I'm here, let's go in. 35 yuan is the only ticket. Xia Haiyan and I have a photo association membership card, so we bought two tickets to enter. Halfway up the mountain, I saw a farmer's restaurant on the roadside. Everyone discussed eating first, so they chose a farmer named Shancun Hotel to enter. Ordered dry pot roast chicken, miscellaneous fish and tofu pot, stir-fried fresh bamboo shoots and stir-fried vegetables. After the dishes were served, the aroma was overflowing, and the appetite increased greatly. Everyone enjoyed themselves. They all felt that if they were on Sujiabu Street, they might not enjoy such green, organic, delicious and inexpensive food.
after coming out of the hotel, everyone has lost the interest in climbing mountains, and they have no plans to go into the mountains, so they are not suitable for mountain roads. After a lot of arguments, I decided to go to xianghongdian reservoir to shoot the scenery.
xianghongdian reservoir is 3 kilometers away from Jiugongzhai, and it will arrive soon. In front of an observation deck on the mountain, we stopped to take pictures. From this position, you can see the whole picture of the dam. On the head-on dam, the big red letter "Be sure to repair the Huaihe River" across the dam is very eye-catching, and the arc dam arched into the reservoir is very spectacular. Looking at the scenery under the dam with a big gap, we all felt the foresight of the project promoters and marveled at the ingenuity of the project builders.
xianghongdian reservoir is located in the upper reaches of Xipi River, and the basin is located in the Jianghuai watershed, with the terrain high in the south and low in the north, with an average elevation of 5 meters. The reservoir hub project consists of four parts: reservoir dam, spillway tunnel, diversion tunnel and power plant. The dam is the first concrete gravity arch dam with equal radius and concentric center designed and constructed by China. Construction started in April 1956 and was completed in July 1958, and water storage began at the same time. The maximum dam height is 87.5 meters, the arc length of the dam crest is 367.5 meters, and the width of the dam crest is 5 meters; A grouting gallery with a width of 2.25m and a height of 2.75m is built in the dam body for drainage and observation and inspection. The spillway tunnel is located on the right bank of the reservoir dam, with a length of 33.9 meters and a diameter of 7 meters. The diversion tunnel is located between the dam and the spillway tunnel, basically parallel to the spillway tunnel, with a total length of 216.5 meters, a main tunnel with a diameter of 8.7 meters, and four parallel branch tunnels with a diameter gradually changing from 3.6 meters to 2.8 meters at the end, which are connected with steel pipes and enter the power plant. The power plant was built in April 1958, with a total installed capacity of 4, kilowatts, and all power was generated in April 1961.
xianghongdian reservoir has beautiful lakes and mountains. It was approved as a national water conservancy scenic spot in July 24, and there are many places to play. But it was a temporary idea, and my wife and her classmates who worked in the reservoir didn't get in touch with each other, so they took a short walk up and down the dam and didn't go further.
On the way back, I turned into Sujiabu Old Street. The old street here has a long history, a large volume, and many ancient buildings, especially the old house in Liu Mingchuan pawnshop, which is quite well preserved. We stood in the middle of the old cross street and looked around. Most of the houses we saw were dilapidated, and the narrow streets were sparsely populated. It seems that the protection and development of Sujiabu ancient town is also difficult.
my wife and I politely declined the hospitality of her two classmates because we were too old to drive late. After dropping them off in downtown Lu 'an, they returned to their homes in Hefei before dark. It seems that this way of playing early and returning late is very suitable for my wife and me, and we can develop more such lines in the future.
