Abstract
A method of making a storage tank system comprises forming a cylindrical-shaped inner tank with integral support ribs and forming a series of interior wall sections which are at least partially separated from the tank's walls between each set of support ribs. Each wall section is preferably bonded to the side walls of adjoining ribs. The walls of the storage tank are strengthened by the support ribs and wall sections.
Claims17
A method of building a strengthened ribbed underground storage tank system from a storage tank formed of a fibrous reinforced resinous material, said storage tank having a cylindrical-shaped main body, end caps and a set of substantially evenly spaced support ribs along the length of the main body which extend circumferentially around said main body and are integral therewith, further wherein said storage tank's interior wall is generally contoured with rib recesses, the improvement comprising bonding a series of wall sections circumferentially around the interior wall of the storage tank to substantially cover interior wall areas between the rib recesses, said wall sections being at least partially separated from the interior wall areas.
A strengthened ribbed underground storage tank system, comprising:
- (a) a fibrous reinforced resinous storage tank having a cylindrical-shaped main body, end caps and a set of substantially evenly spaced support ribs along the length of the main body which extend circumferentially around the main body and are integral therewith, further wherein said storage tank's interior wall is generally contoured with rib recesses;
- and
- (b) a series of wall sections extending circumferentially around the interior wall of the storage tank to substantially cover interior wall areas between the rib recesses, said wall sections being at least partially separated from the interior wall areas.
