Full-scale strength tests on penstock outlets of the Nurek hydroelectric station
Conclusions 1. Owing to the sucessful hydraulic tests an adequate guarantee was obtained for the safe operation of the unencased downstream ends of the first-stage penstocks of the Nurek hydroelectric station, at service pressure. 2. Based on the results of tests at a pressure of 18kg/cm2 it is expected that at 36.8kg/cm2 there will be an overstress of 20% in the reinforcing plates of the manhole T-piece, if the T-piece is not encased in concrete. As the T-piece will be enclosed in a reinforced-concrete lining designed to carry the full internal pressure with a safety factor of the order of 1 its strength can be regarded as guaranteed. 3. The stressed state of the bend corresponds, in the main, with the computed conditions. 4. The tests disclosed no general beam flexure of the downstream end of the penstock.
