Mechanical equipment of spillways of the Charvak, Nurek, and Toktogul hydroelectric stations

Conclusions

• 1. The use of high-head gates similar in dimensions and purpose but differing in design for testing under actual conditions was a useful and justified measure of the Central Asian branch of Gidroproekt — the general designer of the hydroelectric stations — and Mosgidrostal', having greatly broadened experience in their design, manufacture, and assembly.

• 2. To determine the most reliable and expedient mechanical equipment of new high-head hydroelectric stations it is necessary to study thoroughly the results of the operation of experimental gates under actual conditions and to eliminate known defects and troubles in their designs.

• 3. The experience of operating high-head gates indicates the need to make the requirements imposed on the manufacture and assembly of such gates more stringent in order to improve their still inadequate reliability.

• 4. Determination of the most reliable and promising designs of the service and emergency-guard gates for new high-head hydrostations will make it possible to obtain a considerable economic effect.
