Tuanjie Reservoir is located at the southernmost tip of Muling County, in towns and villages, and in the upper reaches of Muling River, with a control basin area of 445 square kilometers. It is a comprehensive reservoir for irrigation, flood control, power generation and fish farming. These key projects include dams, spillways, water tunnels and power stations. (1) The dam is an earth-rock dam with clay core, with a total length of 240m, a maximum dam height of 35.5m and a crest width of 5m, making it the highest earth-rock dam in the province. (2) The spillway is opened on the river bank, with a clear width of 30 meters at the top of the weir, and the steep slope dissipates energy, with a maximum flow of 922 cubic meters per second. (3) The water conveyance tunnel is a reinforced concrete circular tube with a diameter of 3.7m. The upper, middle and lower ends are provided with three-hole flat steel gates and three hoists, with the maximum flow rate of1.47m3/s.. (4) The power station is behind the dam, and the diversion tunnel is a reinforced concrete circular tube with a diameter of 2m and a diversion flow of 5m3/s. ..
Tuanjie Reservoir is a self-reliance project of 1969 Muling County, and 1972 is included in the national capital construction plan. Designed by Mudanjiang Water Conservancy Bureau, Muling County organized the county's strength construction. It was originally designed according to the 50-year flood, and checked by the 500-year flood. Later, it was changed to the once-in-a-century flood design to check the possible maximum flood, with a total storage capacity of 65.438+0.25 billion cubic meters. After being included in the capital construction project, the national investment was1/kloc-0.02 million yuan, which was completed in June 1983. * * * Earthwork works 93 1 10,000 cubic meters, concrete works1.20,000 cubic meters. The designed irrigation area of the reservoir1.2000 mu, and the compensated irrigation area 1.982 is 220000 mu. Flood control benefits come once in a hundred years, reducing flood peak by 94%; The power station has three units with an installed capacity of 750 kilowatts; 1985 generates 345000 kwh; Fish culture water surface is 6240 mu.
