Construction process of Qingshan reservoir

1967 started construction in winter, 1974 completed the early supporting works of the hub and passage, 1985 completed them all. The rain area is 44 1 km2, the length from the dam to the reservoir tail is about 1 2km, the widest point is about1km, and the maximum water depth is about 59m. The main dam with clay core wall is 383m long, 6m wide and 59m high. East auxiliary dam110m, with a height of 24.5m; The west auxiliary dam is 230 meters long and 33.5 meters high. The total storage capacity is 448 million cubic meters, and the effective storage capacity is 208.4 million cubic meters. The clear width of the three-hole spillway is 24 meters, and three arc steel gates with a height of 7.8 meters and a width of 8 meters are installed. The length of reinforced concrete pipeline for power generation is 15 1.8m, the diameter is 3.5m, and the design flow is10.3-75m3/s. The breeding area of the reservoir is 6.5438+0.2 million mu. A bird's eye view of Qingshan Reservoir, shaped like a dragon, runs through North China, Gushi, Gaojian and Daqing in Tongcheng. The county has 60,000 mu of flood control, and 6.5438+0.2 million mu (76,000 mu) can be irrigated with water. Qingshan Reservoir is a large-scale backbone water conservancy and electric power project for flood control, irrigation, power generation, aquaculture and comprehensive utilization of drinking water supply in Tiancheng County. The east-west main canal is dug, with a length of 57.6 kilometers, designed irrigation area of 6.5438+0.5 million mu and flood control area of 6.5438+0.3 million mu. There are 5 cascade power stations with installed capacity of 12225 kW. From 1974- 1985, Qingshan first-class hydropower station generated 3 1 10,000 kwh, and generated income of18.8 million yuan, which played an important role in the development of industrial and agricultural production and the improvement of people's living standards in Chongyang County. Today's young people can hardly imagine the hardships of building Qingshan Reservoir and digging main canals. In 1960s and 1970s, without mechanization, earth and stone were transported to Shi Quan by migrant workers. In addition, the location of earthwork is generally 1 km away from the dam site. A person must carry 25 goods for four or five miles, and a standard worker must walk more than 65,438+000 miles. It's hard to talk about it.

/kloc-in the winter of 0/969, the dam entered the stage of large-scale construction, and mobilized migrant workers from Tongcheng, Puyin, Sun Yicheng and Chongyang counties to form a huge construction team, which was commanded by Zhou Fatian, the former deputy commander (Major General) of a group army of China People's Liberation Army, and fought for a winter. 1970, seven districts in the county employed nearly 30,000 people, and large-scale construction continued. 197 1 winter, 9,000 laborers were put into Shaping, Shicheng, Heping, Sutang and Lukou to continue backfilling the dam. In February 65438, the dam reached the design elevation and the reservoir began to store water.

Qingshan Reservoir was built in 1967, and the project was completed in 1985. A total of 3,537,900 cubic meters of earthwork, 288,400 cubic meters of stonework, 54,700 cubic meters of concrete, 0,8400 cubic meters of masonry and 28.3 million standard workers were completed. State appropriation 17928600 yuan, self-raised 1448700 yuan.

In the process of building Qingshan Reservoir and digging power tunnel, 22 comrades including Shu Shenghou gave their precious lives, and their names and deeds will go down in history with the reservoir project! On the slope of the East Auxiliary Dam, the words "Qingshan Reservoir" written by Mao Zedong are shining in the sun. Someone wrote a poem saying:

The majestic dam is located in the mountains, and purple smoke rises from the sunset lake.

A monument reflects the sky.
