  • the cells are interconnected at their upper and lower ends to permit water flow between the series of cells.

  • the tank shell 2 is lined by a liquid-tight liner 4 fabricated from flexible sheet material impervious to water or other liquid.
  • the liner consists of a peripheral or upstanding wall which conforms approximately to the wall of the shell, and a base sealed relative to the peripheral wall .
  • Baffles 6 of the same or similar flexible material extend between the two longer sides of the liner wall and act as ties between the longer sides , so the baffles perform a similar purpose to the steel baffles previously discussed but instead act to restrict the outward deformation of the sides of the liner when under hydrostatic pressure load.
  • the opposite sides of the tank shell 2 will not be subject to loading tending to cause them to deform outwardly under load.
  • the effect of the baffles 6 is to provide a scalloped shaping at the sides of the liner, the scallop shape being defined by a series of cusps 8 interconnected by portions 10 of relatively large radius .
  • the connection between each end of the baffle 6 and the adjacent face of the liner is a welded connection, details of which are shown in Figure IA.
  • one face of the baffle 6 at its end portion is welded to the inside face of the liner at one side of the cusp 8 which is created by the baffle, and a reinforcing strip 12 of the same plastics material is welded to the other face of the baffle 6 and the inside face of the liner at the opposite side of that cusp .
  • the tank shell itself does not require to be constructed with side walls which are reinforced to carry the hydrostatic pressure loading.
  • the arrangement can include contact between the liner 4 and side walls of the tank shell 2 , provided the contact is such that a substantial part of the hydrostatic pressure loading is carried by the liner.
  • the tank can therefore be transported in prefabricated sections assembled on site .
  • the liner is fabricated from flexible sheet plastics material which is folded into a compact flat pack form for transportation and is then fitted into the outer shell.
  • Figure 2 shows an alternative in which the liner is constructed from a series of separate cylindrical cells 20 of a diameter slightly less than the width of the tank shell 2 whereby each cell will, as a result of its shape, carry the hydrostatic pressure loading uniformly around its periphery without subjecting the side walls of the shell to substantial, if any, loading which tends to cause them to deform.
  • the cells 20 are interconnected at their upper and lower ends to permit liquid flow between the series of cells .
  • Figure 3 shows the basic configuration of preferred embodiments of the invention. This configuration can be achieved with a number of alternative constructions as will be described subsequently, but first the basic configuration itself will be described.
  • the configuration consists of a cell 30 at each end of the liner and which is supported against the adjacent curved end of the shell 2 , and one or more intermediate cells 32 between the end cells 30. As shown, there are three intermediate cells 32 but there may be more than or less than three intermediate cells 32 depending on the overall length of the tank shell .
  • the configuration of the liner is such that when the liner is installed and filled with water or other liquid and under hydrostatic pressure loading, the end cells 30 will be braced against the curved end walls of the shell and will cause the intermediate cells 32 to be compressed into the general shape illustrated in which the cell is elongated transversely to the longitudinal axis of the shell.
  • the engagement of the end cells 30 with the rounded ends of the tank shell will result in some of the hydrostatic pressure loading being taken by the rounded ends and as will be understood, by reason of their shape they are inherently able to take that loading without deformation .
  • This arrangement is essentially self-supporting.
  • the overall peripheral shape of the liner is broadly similar to that: shown in Figure 1 the rounded ends of each cell 32 are deformed to a smaller radius than that shown in Figure 1.
  • This reduction in radius which also occurs in the portion of the end cells 30 adjacent the next intermediate cell 32 , results in a reduction in the skin tension of the liner when under load which provides constructional advantages as will be described.
  • the resulting radius reduction reduces the amount of unusable or wasted space within the tank shell as may be seen by comparing the configuration of Figure 3 with that of Figure 2.
  • Figure 4 shows a practical embodiment of the present invention utilising the concept.
  • the liner is formed from a series of separate cells 30, 32 each closed at the base and possibly also at the top.
  • the peripheral wall of each cell is formed by fabricating sheet material into tubular form and then welding that to a base.
  • a separate base may be provided for each cell or alternatively the cells may be welded to a common base.
  • a separate base for each cell has advantages in terms of facilitating packing and transporting the liner as a compact flat-pack. This is an important consideration .
  • the shape of each base is selected to be the shape required for the base when the cell is installed in the tank shell and filled with water .
  • the base and the peripheral wall of each cell can be connected together by any suitable means.
  • One particularly suitable option is to heat weld the components together where the components are formed from suitable materials.
  • forming the separate base for each cell from a rigid of semi-rigid material has advantages in terms of installing the liner in a correct position in the tank shell initially and thereafter maintaining the liner in the correct position over time as the liner changes shape as water is supplied into and is discharged from the tank. In this regard, the applicant has found that maintaining the liner in position in the tank shell is an important consideration.
  • forming the separate base for each cell from a rigid or semi-rigid material is advantageous in allowing easier replacement of a liner. Instead of closing the cells by a base, the cells can be closed at the bottom by welding together their lower edges.
  • the adjacent cells of the liner are connected by sealed ports at least at their lower ends to permit liquid flow between the cells .
  • the circumferential size of each of the intermediate cells 32 is less than that of the two end cells 30 (but may alternatively be the same as the end cells) and the sizes of the cells 30 , 32 in relation to the size of the tank shell is such that with the liner placed within the tank shell and filled with liquid, the configuration shown in Figure 3 will be obtained.
  • the liner also comprises clips (not shown) or other suitable members at upper ends of the walls of the cells that are formed to hook over the rim of the tank shell or otherwise connect the liner to the tank shell to facilitate hanging the liner in a selected orientation within the tank shell.
  • the use of this clip assembly avoids the liner collapsing to the bottom of the tank when the liner is empty. This is an important consideration given that the liner will hold different amounts of water over time.
  • the liner is also advantageously formed with water inlet and water outlet openings , and appropriate fittings for connecting water inlet and outlet assemblies to the liner when the liner is installed in a tank shell are connected to the inlet/outlet openings . It can be appreciated that the liner, so formed, can be conveniently transported to an installation site and unfolded and positioned in a tank shell .
  • adjacent cells may be constructed from separate panels of sheet material welded together so that a single panel forms a wall common to two adjacent cells, that wall being a substantially straight wall extending transverse to the side wall of the tank shell .
  • Alternative arrangements for achieving this are shown in Figures 5 and 6.
  • the individual panels are designated 40a to 4Oe
  • the zones of the welded connections between the panels are designated 42
  • the transverse walls common to adjacent cells are designated 44.
  • the cells formed by the assembled panels are closed at the bottom by a base layer of sheet material welded to the panels.
  • the individual panels in the zone of the walls 44 common to two adjacent cells may remain unsealed to the base panel to permit passage of water, and the lower edge of the panel in this zone may be profiled to provide a large area flow port.
  • the peripheral configuration of the liner with a scalloped shape of tight radius as shown in Figure 3 can be induced by welding baffles between the opposed sides of the liner . See Figure 7.
  • the difference between this and the configuration shown in Figures 1 and IA is that the tighter radius allows the baffle 6 now to be welded to a part of the liner wall which is directed transversely to the side wall of the shell so that the welded connection is now under a shear loading rather than the tensile loading subject to failure by peeling inherent in the configuration of Figures 1 and IA.
  • the tighter radius also results in a reduction in skin tension and a consequent reduction in the loading applied to the welded connection .
  • the end of the baffle 6 is welded to the internal face of the liner at one side of the cusp 8 , and at the other side of the cusp 8 a reinforcing strip 12 of the same material is welded to the other side of the baffle and the internal face of the liner.
  • the end of the baffle 6 is welded through the two layers which define the cusp 8 thereby bonding the two layers and avoiding the need for the reinforcing strip present in Figure 7.
  • Figure 9 shows a variant of a scalloped shape induced by welding baffles between the opposed sides of the liner and, in effect, represents an intermediate configuration between that shown in Figure 1 and that shown in Figure 3.
  • the scalloped shape is to a tighter radius than that shown in
  • FIG 10 shows an embodiment in which the baffles 6 extend horizontally in the lengthwise direction of the liner and are vertically spaced.
  • the baffles extend along the length of the opposite sides of the liner and possibly also into part of the end zones of the liner and provide a scalloped shaping in vertical cross-section as is clearly shown in Figure 10.
  • the baffle spacing reduces towards the bottom of the liner and the scallop curvature becomes tighter towards the bottom and this maintains an even skin tension along the height of the liner despite the increasing pressure towards the bottom.
  • the liner is supported from the shell by suspending from the top of the shell, and fabric panels or straps 50 extending vertically are secured to the external faces of the cells to maintain them at the correct height when the liner is empty.
  • the liner may be open or closed at the top.
  • a variant of the configuration shown in Figure 10 can be produced by a series of separate, but interconnected, tubular cells arranged with their axes extending substantially horizontally. Although reference has been made herein to welded, connections between various components forming the liner, the connections may alternatively be glued connections and to an extent this will be determined by the nature of the fabric used.
  • the walls of the liner and the baffles are fabricated from flexible sheet material of appropriate characteristics to ensure it has sufficient strength to withstand the hydrostatic pressure loading to which it will be subjected in use.
  • the fabric must be able to support tension loads over a prolonged period of time without stretching while having resistance to abrasion and to temperature to withstand solar heating via the shell of portions of the liner above water level .
  • Suitable materials may be composed of a scrim or woven fabric having an impervious coating on one or both sides and such materials are already commonly used for tarpaulins and tank liners of other types. In situations where the tank is to be used for storing water, the impervious coating should be a food grade quality material .
  • Mien a base is used to close the cells, as it is not subject to the same tension loading as the walls and baffles, it may not necessarily need to be fabricated from the same material as the walls of the liner . Similar considerations apply for a top closure (if present) at the upper ends of the cells .
  • the base may alternatively be of a semi-rigid material and which may be cut to the same shape as the shell , thereby making it easy to drop the liner into the shell and self-locate, as described above in relation to the Figure 4 embodiment.
  • a liner in accordance with the broad principles of the invention could also be fabricated for use with an elongate shell having squared or any other shaped ends provided that the ends are of a size and/or construction such that they will not deform outwardly when subject to hydrostatic pressure loading.
