Problems solved by technology

The water intake of the hydropower station is usually set at the lower part of the water retaining dam, resulting in the discharge of low-temperature water to the downstream, which reduces the temperature of the water flow measured downstream of the dam, which in turn has a certain adverse effect on the growth of downstream aquatic organisms

Abstract

The invention discloses a sectional curtain water barrier structure. The sectional curtain water barrier structure comprises a horizontal inhaul cable structure and a multi-section curtain water barrier structure, wherein the horizontal inhaul cable structure comprises concrete anchorage piers and a horizontal inhaul cable; the concrete anchored piers are arranged on two sides of the river bank; two ends of the horizontal inhaul cable are anchored on the concrete anchorage piers respectively; the horizontal inhaul cable is higher than the maximum water level of a reservoir; the multi-section curtain water barrier structure is formed by a plurality of curtain water barrier structures which are connected with each other in parallel. The sectional curtain water barrier structure is capable of effectively preventing low-temperature water in the lower part of the reservoir from flowing to a water intake of a power plant, so that the surface water of the reservoir is frequently taken when in water taking; the discharging water flow temperature of a hydropower station is increased; the influence of power generation discharging water flow on the temperature and the content of oxygen of the downstream river channel is reduced; growth and development of downstream aquatic organisms are facilitated; the structure is also capable of adjusting the curtain water barrier range according to different water depths, thus ensuring that the surface water can pass through the curtain water barrier structure.

Description

technical field [0001] The invention belongs to the technical field of dam construction, and relates to a water-retaining structure using a screen to block low-temperature water in the lower part of a reservoir, in particular to a segmented screen water-retaining structure. Background technique [0002] The water body temperature of deep-water large reservoirs generally has obvious temperature stratification along the depth direction, that is, the temperature of the surface layer is high, and the temperature of the bottom layer is relatively low. Especially in summer, the temperature difference between the surface water temperature and the bottom water temperature of the reservoir can reach 20 degrees Celsius. The water intake of the hydropower station is usually set at the lower part of the water retaining dam, resulting in the discharge of low temperature water to the downstream, which reduces the temperature of the water flow measured downstream of the dam, and has a cert...
