The invention concerns a tank for a fluid product, having a bottom (4) and a resistant side wall (10) composed of juxtaposed prefabricated panels (1) each comprising a wall element (2) covered, on an internal face (22), with a continuous sealing sheet (3) extended by three sections (33, 33′, 34) which cover respectively the lateral sides (23, 23′) and the lower side (24) of the wall element (2) and overlap on the outside of the wall (10). Said panels are placed on a slab (4) covered with a sealing sheet (42) and the adjacent overlapping sections of the sealing sheets (3, 42) covering the set of the panels (1) and the bottom (4) are connected together in a sealed fashion.Such a tank which is easy to build and to maintain, can contain drinking water or a polluting product.

1. A tank for a fluid product, having a bottom and a resistant side wall composed of juxtaposed prefabricated panels and covered, on an internal face, by a sealing sheets,wherein each prefabricated panel comprises a wall element having a sufficient thickness to sustain the pressure of the fluid, with two lateral sides, an upper side and a lower side and covered, on an internal face, with a continuous sealing sheet extended by three sections covering respectively the lateral sides and the lower side of the wall element and each extending over a length greater than the thickness of the element in order to extend outside the wall by a overlapping section, in that said panels are applied against one another by their lateral sides and rest, by their lower side on a slab forming the bottom of the tank and covered with a sealing sheet having a peripheral overlapping section extending outside the wall placed on the slab, and in that the adjacent overlapping sections of the sealing sheets covering the set of panels and the bottom are connected together in order to delineate a scaled tank, the lateral overlapping sections of the sealing sheet of each panel being connected in a sealed fashion with the lateral overlapping sections of the adjacent panels and the lower overlapping section being connected with the peripheral section of the sealing sheet covering the bottom of the tank. 2. A tank according to the claim 1, wherein the sealing sheet covering each panel and the bottom is composed of a metal adapted to the fluid (E) and in that the overlapping sections of the sheets of the panels of the wall and of the bottom are connected together by welding or crimping their external edges.3. A tank according to the claim 2, wherein the sealing sheet covering each panel and the bottom is made of stainless steel.4. A tank according to claim 1, wherein the sections of the sealing sheets covering the panels are connected together and with the sheet covering the bottom, by gluing.5. A tank according to claim 1, wherein the overlapping sections of the sealing sheets extending outside the wall are grounded electrically in order to provide cathodic protection.6. A tank according to claim 1, wherein it comprises linking means between the adjacent panels enabling to sustain the pressure of the fluid (E) contained in the tank.7. A tank according to the claim 6, whereof the wall extends in height up to an upper level, characterised in that the linking means between adjacent panels are placed above the upper level of the wall and comprise at least one linking member forming a belt surrounding externally the set of panels at a distance from the internal face of said panels greater than the distance (a) between said internal face and the external edges of the sealing sheets.8. A tank according to the claim 7, wherein each resistant element of a panel is fitted with a section overlapping outwardly from the external face of said element, and in that the overlapping sections of the adjacent panels are placed in the extension of one another and are connected together by at least one oblong linking member counteracting, in operation, the stresses tending to spread two adjacent panels apart from one another.9. A tank according to the claim 8, wherein the linking member between the adjacent panels comprises at least one prestressing cable or bar resting on the overlapping sections of the panels and subject to a traction load for clamping said panels together.10. A tank according to the claim 6, composed of panels extending in height at least up to a maximal level of the reserve capacity, characterised in that the linking means between the panels form a belt extending above said maximal level and fitted with means of interconnection with each of the panels.11. A tank according to the claim 10, wherein the interconnection belt is composed of beam elements arranged behind one another, along the upper section of the wall, each element extending on both sides of at least one jointing plane between two adjacent panels and being interconnected with said panels.12. A tank according to claim 10, wherein the interconnection belt is composed of at least one oblong part having, in cross section, a U-shaped profile and covering the upper section of the panels.13. A tank according to claim 1, wherein the slab is fitted, over its whole contour, with a groove wherein engages at least one overlapping section of the lower side of each panel.14. A tank according to claim 13, wherein the lower side of each panel is widened in order to form a stabilisation foot which engages into a groove with corresponding width, arranged on the periphery of the slab forming the bottom of the tank.15. A tank according to claim 13, wherein the sealing sheet covering the slab is formed according to the hollow profile of the groove in order to emerge from said groove while extending up to an external edge placed substantially at the upper face of the slab and in that the lower side of the sheet covering each wall element goes up along the external face of said element and extends up to an external edge which, after embedding of the panel, lies substantially at the upper face of the slab, in order to be connected to the external edge of the sheet covering said slab.16. A tank according to claim 1, wherein the lateral wall of the tank having a polygonal shape comprising several faces planes connecting at an angle, the wall comprises, at each angle, an elbowed panel having two branches which connect each at a plane panel forming at least one section of the plane face of the wall.17. A method of construction of a tank having a bottom and a lateral wall, wherein the bottom is realised first of all, while casting a concreted slab whereon a continuous sealing sheet having a peripheral overlapping section is applied, in that a set of juxtaposed prefabricated panels are laid on the periphery of this slab to form a wall, each comprising one resistant element covered with a sealing sheet extended by three sections covering respectively both lateral sides and the lower side of the element and extending each over a length greater than the thickness of said side in order to extend outside the wall by a overlapping section and in that a sealed link is realised, on the one hand, at the bottom, between the peripheral overlapping section of the sheet covering the slab and the lower overlapping section of the sheet folded on the lower side of each panel and, on the other hand, in each jointing plane between two panels, between the overlapping sections of the sheets folded on the adjacent lateral sides of said panels.18. A method according to claim 17, wherein the tank is buried, at least partly, in a pit and in that, after realising the bottom and the wall and the welding of the external edges of the sealing sheets, a backfill is placed around the lateral wall, said backfill providing the interconnection of the juxtaposed panels.19. A method according to the claim 18, wherein the overlapping sections of the sealing sheets covering the panels of the wall and the bottom are buried, at least at their lower section, in the backfill made around the wall and which constitutes an electrical ground providing the cathodic protection of the sealing sheet.20. A method according to claim 17, wherein an interconnection belt is realised, at least at the upper section of the panels, above the maximal level of the product contained in the tank.
