ABSTRACT:
Closure elements uniformly spaced at the periphery of a concrete plug are each applied at one end against the top face of the plug and at the other end against the corbel of a prestressed concrete pressure vessel. Each closure element is constituted by a hydraulic jack whose closed extremity is coupled to a first articulated bearing shoe. Adjustable mechanical means within the jack body maintain this latter in contact with an annular shoulder of the jack piston in all relative positions, the emergent extremity of the piston being coupled to a second articulated bearing shoe.
