PURPOSE:To make the setting of a servomotor attainable without any damage to a hydraulic turbine installation building and related machinery and equipment, by embeddedly setting up plural numbers of supporting blocks so as to support the weight of structural parts altogether. CONSTITUTION:Plural numbers of supporting blocks 20 are embeddedly set up in annular form on a floor inside a lower assembling room in and around a reversible pump-turbine. Each of them is installed so as to support the weight of a casing 1, a stay ring 2 and an outward turnover vane 5 and simultaneously made up as a setting block for a lower stage guide vene 6 and a lower stage servomotor 18. The top of each supproting block 20 is firmly locked by a bracked metal device 23 projected from those of casing 1, stay ring 2 and outward turnover vane 5, While the lower part is locked with an iron reinforced rod or foundation bolt, etc. |
