8. The interlocking panel of claim 3 , further comprising at least one ring attached to at least one retaining rib.
9. An above ground large capacity tank, comprising:
a plurality of identical, stacked, and interlocked interlocking panels, each of the interlocking panels comprising:
a plate with an outer surface, an inner surface, a bottom edge, a top edge, a first side edge, and a second side edge opposite the first side edge;
a first flange extending from the first side edge of the plate and having at least one fastener hole extending through the first flange;
a second flange extending from the second side edge of the plate and having at least one fastener hole extending through the second flange;
a third flange extending from the top edge of the plate and having at least one fastener hole extending through the third flange;
a fourth flange extending from the bottom edge of the plate; and
at least one guide pin provided on the third flange and configured to extend into at least one guide pin hole of a second interlocking panel positioned above and engaged with a first interlocking panel,
wherein the at least one guide pin is located on the third flange to engage the at least one guide pin hole of the second interlocking panel such that the second interlocking panel is offset vertically relative to the first interlocking panel located below the second interlocking panel, and
wherein the first flange and the second flange comprise a plurality of fastener holes extending therethrough, and wherein bottom ends of the first flange and the second flange include a greater number of fastener holes than top ends thereof to provide additional support against fluid pressure that develops in the bottom of the large capacity tank.
10. The large capacity tank of claim 9 , wherein the plate and each of the third flange and the fourth flange have an arcuate shape.
11. The large capacity tank of claim 9 , further comprising a plurality of retaining ribs on the outer surface of the plate and extending between the first flange on the first side edge of the plate and the opposing second flange on the second side edge of the plate.
12. The large capacity tank of claim 11 , wherein the plurality of retaining ribs are evenly spaced between the third flange at the top edge of the plate and the fourth flange at the bottom edge of the plate.
13. The large capacity tank of claim 11 , further comprising a plurality of vertical support members positioned on the outer surface of the plate and extending between the retaining ribs on the outer surface of the plate.
14. The large capacity tank of claim 13 , wherein the vertical support members extend between adjacent retaining ribs on the outer surface of the plate.
15. The large capacity tank of claim 11 , further comprising a plurality of vertical support members positioned on the outer surface of the plate and extending between at least one of the third flange and one of the retaining ribs and the fourth flange and one of the retaining ribs.
16. The large capacity tank of claim 11 , further comprising at least one ring attached to at least one retaining rib.
17. A method of assembling an above ground large capacity tank, comprising the steps of:
providing a plurality of identical interlocking panels, each of the interlocking panels comprising:
