Development course of Xiashan Reservoir

At that time, the main purpose of building this reservoir was to solve the flood disaster, farmland irrigation and coastal people's draught problems on both sides of the lower Weihe River. Historically, the Weihe River was once called the Huaihe River. Because of its frequent breaches, it caused great losses to people's lives and property, so the people on both sides of the lower reaches called it the "bad river". In the past, people in Changyi and Weixian used to say: "The Wu family is full, and Changyi and Weixian also follow. As soon as Hongyakou opened, Changyi and Weixian followed closely. " "Opened the family bay and flooded eastward for half a day. After crossing the Jiaolai River, Sanhe Mountain was flooded. "

The construction of Xiashan Reservoir is directly led by Changyi prefectural committee and agency, and migrant workers from Changyi, Gaomi, Anqiu and wei county are organized to participate in the construction. The Department of Health and the prefectural party committee set up the reservoir construction headquarters and the reservoir engineering party committee, with Deputy Commissioner liuyong as the chief commander and party secretary, and Deputy Commissioner Zhang Xingtang as the deputy chief commander and deputy secretary of the party committee. The headquarters consists of office, engineering department, supply department, equipment and machinery department and relocation department. The Party Committee of the Reservoir Project has a Political Department, and the Political Department has an Organization Department, a Propaganda Department, a Security Department and a Youth League Committee. Zhang Jun is the director of the political department. During the construction of Xiashan Reservoir, the main person in charge of the reservoir engineering headquarters has changed three times, the first is Wang, the second is Wang, and the third is Zhang Jingyie. Wang's term of office was short, and Zhang Jingye's term of office was the longest, until the reservoir was completed.

The reservoir engineering headquarters consists of four counties, and the headquarters was established, which was commanded by the deputy commander at that time. Sheng Yongzheng, then secretary of Changyi County Committee, Fan Xuefa, then member of Changyi County Committee and executive deputy magistrate, Wang Peilin, then deputy magistrate of Gaomi County, and Zhu Tong, then deputy magistrate of Gaomi County, were appointed to Gaomi County Supervision Institute to inspect Liu Yongsen, then member of the Standing Committee of Anqiu County Committee of Chang 'an County and minister of propaganda. Wang Chunwei, deputy magistrate of Wei County, started from 1958 to 10. The county has set up a "regiment", a "battalion, company and platoon" with commune, agricultural area and production team as units, and implemented the management mode of "militarization of organization, combat of action and collectivization of life", and the enthusiasm for construction has never been higher. However, due to the poor tools and the hard life of migrant workers at that time, the progress and quality of the project were affected to some extent, which laid a hidden danger for the future construction management.

From June 1958 to October 165438+ Spring 1959, the main task of construction is to clean up the dam foundation.

From February to the end of 1959, the key point was to build the dam, spillway, power station and sluice simultaneously. The power station and sluice were completed that year, but the hydro-generator could not be installed due to shortage, and the power generation was installed at 1963.

1960 spring, the original river channel was closed, and the river channel was diverted to take the diversion ditch of Nanpeigezhuang in Anqiu.

April 2 1960 dam closure. Three counties participated in the river closure, Wei County in the north, Changyi in the middle, Anqiu and Changyi in the south, which were completed at the earliest. The full closure was completed in June. Then by June 5438+00, the stone slope protection of the dam was basically completed. At this point, the construction of Xiashan Reservoir is basically completed. After that, the spillway stilling basin construction, water conveyance tunnel construction, filter layer restoration and other projects were carried out one after another.

In August 1960 and 12, the inflow of Xiashan Reservoir reached 6830 cubic meters per second. The people on both sides of the reservoir dam and Weihe River are safe and sound.

1September, 960, the reservoir was completed and stored. There are seven drainage tunnels. Anqiu irrigation area takes water from Buwangzhuang drainage tunnel at the southern end of the main dam. The diameter of the drainage tunnel is 2m, and the designed flow rate is 3.5m3 per second. Completed on 1964, mainly responsible for the irrigation task of 35,000 mu in Chaoge Town.

In August 1974 and 13, the Weihe River was flooded more heavily, and the inflow reached 10400 cubic meters per second. The reservoir once again played a role in flood control and saved the day. These two floods, if there is no Xiashan Reservoir, will certainly have a devastating disaster in the lower reaches of the Weihe River. Xiashan Reservoir has effectively protected people's lives and property.

1976 began to use 10 to build a reservoir safety project.

From 65438 to 0986, the reinforcement project was carried out, and all the projects achieved excellent results, which promoted the benefit of the reservoir project.

1992 power station transformation, the first-class 1 500 kW unit capacity increased to 650 kW, and the second-class 1 650 kW unit was added, and the current total installed capacity reached 3475 kW.

1996, in order to solve the contradiction of excessive immigrants in the reservoir area, the Anqiu Municipal Party Committee and the Municipal Government made bold decisions and implemented the beach reconstruction project, with an investment of 2 1 10,000 yuan, a dam of 23,000 meters and a land reconstruction of 2130,000 mu. Planting fish (lotus root) in forest (grain) in the transformation area has greatly increased economic benefits. Zhaoge Town was named "the hometown of freshwater culture in China" by the Ministry of Agriculture because of its large pond culture area and high quality.
