Zhuzhuang reservoir is located near Zhuzhuang village, Qicun Town, Shahe City, Hebei Province. It is a large (II) type water conservancy project on Shahe River, a tributary of Fuyang River in Ziya River system of Haihe River Basin, which is mainly for flood control and irrigation, and also for comprehensive utilization of power generation and urban water supply. The control basin area is 1220km2, and the engineering grade is grade II. At the same time, the beautiful scenery and fresh air around the reservoir make it a good place for tourism.

Basic information

Zhuzhuang reservoir is located in the west of Zhuzhuang village, Shahe City, Xingtai. In the upper reaches of Nanli River, it receives water from dozens of rivers and valleys in Xingtai, Shahe and Neiqiu counties, with a control area of more than 1200 square kilometers. It is a large reservoir for comprehensive utilization of flood detention, irrigation and power generation. The whole reservoir can store 700 million cubic meters of water, with a total water surface of 24000 mu. It can safely store the flood with a return period of 20 years, so that the eastern counties will be free from the harm of flood. Two main canals, North and south, are led from the reservoir to irrigate the 380000 Mu "wangtiantian" in Shahe and the mountainous and hilly areas of Xingtai County. Power stations are also built at the head of the two main canals, which can generate 7.4 million kilowatts per year. In addition, 10000 mu of breeding area will be opened up in the reservoir, and 1.5 million fry will be put in each year. It is estimated that the annual output of fresh fish can reach more than 200000 Jin.

Engineering construction

Zhuzhuang reservoir is designed by Hebei water conservancy and Hydropower Survey and Design Institute. The construction started in October 1971. After the installation of the sluice gate was completed at the end of 1976, the flood storage began. By the end of 1981, the main works had been completed according to the approved design. In July 1982, the Provincial Department of water resources and Xingtai Regional Administration jointly formed an acceptance team to carry out the preliminary inspection. In April 1985, the project was officially completed and accepted. During this period, a total of 1.16 million cubic meters of soil and gravel excavation, 642900 cubic meters of stonework excavation, 450900 cubic meters of mortar masonry, 626800 cubic meters of concrete and reinforced concrete, 22200 cubic meters of curtain grouting, 10800 cubic meters of deep hole consolidation grouting and 9800 cubic meters of drainage hole were completed.

Main body design

Dam: it is a concrete masonry gravity dam with a total length of 544m and a height of 95m, of which the height above the riverbed is 65m. The upstream is provided with masonry wave wall. This type of dam is the first in the province.

Spillway tunnel: 1800 discharges can be discharged in flood season. Each spillway tunnel has a gate 14 meters high and 12 meters wide, weighing 24 tons, made of high-quality steel plate. The gate is closely matched with the gate slot, and the gap is not more than 2mm. The bottom spillway is a three hole non pressure tunnel, the tunnel body is gate shaped, and the inlet is a radial steel gate; the water discharge tunnel is a horseshoe shaped non pressure tunnel, and the radial steel gate is set in front of the tunnel.

Overflow dam: 6 radial steel gates and 6 hoists are set on the overflow dam weir; two stilling basins are set at the downstream.

The total storage capacity is 416.2 million cubic meters, the flood control storage capacity is 282.2 million cubic meters, the Xingli storage capacity is 228.5 million cubic meters, the dead storage capacity is 34 million cubic meters, the dead water level is 214.0 m, the starting and regulating water level is 243.0 m, the flood limit water level is 243.0 m, the normal water level is 251.0 m, the design flood level is 255.3 m, and the check flood level is 260.24 M.

major function

Hydropower station: the total installed capacity is 4200kW. Among them, the capacity of low turbine assembly is 3200kW (1 set), the design head is 30.5m, and the design power generation flow is 12.4m3/s; the capacity of high turbine assembly is 2 × 500kW, the design head is 16.0m, and the design power generation flow is 7.84m3/s.

Reservoir inundation treatment: the land acquisition elevation of Zhuzhuang reservoir is 255.0m, the inundated farmland is 6001 mu, the resettlement elevation is 261.5m, and the migration population is 6327.

Irrigation and water supply: the original designed irrigation area of Zhuzhuang reservoir is 380000 mu. Due to the limitation of the supporting capacity of the downstream water diversion hub, the annual actual irrigation area of Zhuzhuang reservoir is about 140000 Mu since its establishment. However, the water supply from the north main canal to Xingtai City has not been realized, and the average water supply of the reservoir for many years is 40.3 million cubic meters. At present, Zhuji Xingtai water diversion project has been completed, which can supply 53 million cubic meters of water to Xingtai City every year.

Flood control: the original design standard is 100 year return period flood and the check standard is 1000 year return period flood (10000 year return period checking calculation); according to the current relevant specifications, the reservoir design standard is 100 year return period flood and the check standard is 2000 year return period flood; the dam safety check shows that the flood control standard reaches 10000 year return period. The flood in 1996 was intercepted and the peak discharge was reduced.

Watershed characteristics

Zhuzhuang reservoir is located on Shahe River, a tributary of Fuyang River in Ziya River system. It controls four mountains and rivers about 30km in length, with a drainage area of 1220km2 and a total storage capacity of 4162 million cubic meters. The average annual rainfall is 639mm, the average annual water surface evaporation is 1170 mm, the average annual land surface evaporation is 450 mm, the average annual runoff is 240 million cubic meters, and the average annual sediment discharge is 740000 t. The historical maximum inflow peak discharge is 9760 m3 / S (equivalent to 200 year return period), which occurred on August 4, 1996. The historical maximum flood level is 258.79m (Dagu elevation, the same below), which occurred on August 4, 1996.
