Basic direction of the improvement of gate seals in hydraulic structures

Conclusions

• 1. In recent years, a large volume of work has been carried out in connection with the development of new types of sealing for operation under heads of up to 120 m.

• 2. The operation of deep segmental gates at the Charvaksk hydroelectric plant over a period of two years confirmed the satisfactory functioning of the sealing elements of deformable-hydraulic action.

• 3. The operation of deformable seals has been comprehensively studied under laboratory conditions and such seals are now installed at the Nureksk hydroelectric plant.

• 4. For high-head gates operating under heads of 150 m and over, it is necessary to continue with the work relating to the development of new types of sealing elements.
