Conclusions

  1. 1.

    The hydraulic testing of the turbine penstock permitted the elimination of several defects detected in its shell. Of the two types of bulkhead flanges used in the tests, the erection of the plane flange is considerably simpler.

     
  2. 2.

    The installation of a drain ahead of each line of the penstock permits the water leaking through the gate seals, when the gate is closed, to be intercepted and discharged through outlet pipes into a ditch. The use of such drains can be recommended at similar hydroelectric stations.

     
  3. 3.

    Because the removal of the internal bracing of the transition chambers in the penstocks was carried out by oxygen flame cutting, which causes local heating of the lining and its peeling away from the concrete, the number of braces should be reduced to a minimum and external ribs of sufficient stiffness adopted instead.

     
  4. 4.

    In addition to by-pass pipes connecting the draft-tube chambers, it is also desirable to provide pipes for the direct communication of the draft tubes to the tailwater, for the equalizing of water levels before raising a maintenance gate, regardless of whether or not there is water in the other pipes.
