Improvement of the mechanical equipment of high-head spillways

  • Published:
Hydrotechnical Construction Aims and scope

Conclusions

  1. 1.

    The wide range of computational, development, and experimental model investigations of the designs of high-pressure emergency-guard gates and main regulating gates, their movable parts and seals, hydraulic lifting gear of large capacity, gate chambers, and schemes of surplusing works performed in recent years showed the real possibility and economic expediency of manufacturing mechanical equipment for regulating large waste discharges at a head of 200 m.

  2. 2.

    Studies showed also the effectiveness of using the effect of swirling of the discharging flow in spillway systems.

  3. 3.

    Further perfection of the mechanical equipment of high-head spillways should improve the layouts, increase the precision and quality of manufacturing gates and drives, operating reliability of the seals, vibration resistance, and protection from cavitation.
