ABSTRACT:
A hydraulic pump/turbine discharge ring leveling, supporting and anchoring apparatus is disclosed which includes a prestressed anchor stud (21) connected between an upper foundation ring (28) and a flange portion (17') of a pump/turbine discharge ring (14) to secure the discharge ring (14) to the upper foundation ring (28). Prior to prestressing the anchor stud (21), a jack-bolt (43) mounted beneath the flange portion (17') is moved upwardly into engagement with the flange portion (17') of the discharge ring (14) to effect a leveling of the discharge ring (14). Thereafter the anchor stud (21) is prestressed by turning down a nut (54) engaging an end of the stud (21) projecting upwardly through the flange portion (17') of the discharge ring (14). The upper foundation ring (28) is anchored to a lower foundation ring (22) embedded in a concrete foundation structure (12), by a plurality of prestressed anchor bolts (23) each extending through the upper foundation ring (28), through a sleeve (24) between the upper and lower foundation rings (28, 22) and through the lower foundation ring (22). The sleeves (24) are also embedded in the concrete foundation structure and have an internal diameter larger than the outer diameter of the anchor bolts (23).
