Abstract
Abstract A reservoir, for example, for liquids capable of being immersed under water and being formed of prestressed concrete. The reservoir has a cylindrical body closed at its ends and lying with its axis horizontal. The reservoir is provided with two partitions which extend from the interior of the body outwards and each of which presents a support foot such that the reservoir can be supported on an emplacement under water at only two points along its length, the partitions inside the body are provided with access openings to permit liquid flow past the partitions and the body may also include other partitions which do not extend out of the cylindrical body and which are also provided with openings for liquid flow.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
169 words
A process for producing and locating an assembly of immersible reservoirs formed of prestressed concrete, each of which reservoirs comprises a cylindrical body, at least two partitions integral with said cylindrical body and perpendicular to the axis thereof and projecting beyond the exterior of the cylindrical body, together with support feet for supporting said reservoir on an emplacement, which process comprises the steps of forming a plurality of said reservoirs independently of one another, partially immersing said reservoirs in calm water so that they float at the same level, locating said reservoirs side by side with the partitions therein in alignment, passing tie means into the holes in said partitions to interconnect the different reservoirs, tensioning said tie means, forming a concrete interconnection between the partitions of adjacent reservoirs, floating the resulting assembly of reservoirs to a position above a foundation on which it is to be permanently located, and completing the immersion of said reservoirs by filling them until said support feet come to rest on said foundation.
Claim 2
Dependent Claim
169 words
A process for producing and locating an assembly of immersible reservoirs formed of prestressed concrete, each of which reservoirs comprises a cylindrical body, at least two partitions integral with said cylindrical body and perpendicular to the axis thereof and projecting beyond the exterior of the cylindrical body, together with support feet for supporting said reservoir on an emplacement, which process comprises the steps of forming a plurality of said reservoirs independently of one another, partially immersing said reservoirs in calm water so that they float at the same level, locating said reservoirs side by side with the partitions therein in alignment, passing tie means into the holes in said partitions to interconnect the different reservoirs, tensioning said tie means, forming a concrete interconnection between the partitions of adjacent reservoirs, floating the resulting assembly of reservoirs to a position above a foundation on which it is to be permanently located, and completing the immersion of said reservoirs by filling them until said support feet come to rest on said foundation.
Claim 3
Dependent Claim
25 words
A process according to claim 1, in which, before tensioning of the cables or tie rods, blocks are located between the partitions of different reservoirs.
Claim 4
Dependent Claim
16 words
A process according to claim 2, in which the different partitions are continuously interconnected by concreting.
Claim 5
Dependent Claim
17 words
A process according to claim 1, in which a plurality of rows of superimposed reservoirs are interconnected.
