•Strapping <br />• Use only Fluid Containment fiberglass anchor straps. <br />• <br />• Place anchor straps between the arrows (►•) on the tank <br />sides over each designated rib location. <br />• Use anchor straps specifically designated for each diameter <br />of tank. Curvature of strap matches each tank diameter. <br />• Properly space anchor points: <br />❑ The proper distance between anchor points is: <br />• Tank diameter plus one deadman width for con- <br />crete deadmen. <br />• Tank diameter plus 12" to 24" for concrete <br />anchor pad. <br />❑ Place anchor points on both sides of tank. <br />❑ Anchor points must be aligned with designated ribs <br />(►•) +1"• <br />• For double-wall tanks, <br />❑ Anchor straps must be placed in the strap guides <br />on each designated rib (►�). <br />• For single-wall tanks, <br />❑ Anchor straps must be placed on top of each <br />designated rib (D-4). <br />Wire Rope ,� FRP Strap <br />Triple Syme E <br />Clamp Double Wall /aeegeu�i <br />\ Tank <br />0, OEM WMA <br />Dead Man Anchor Pad System <br />Anchor System <br />Tank End View <br />Fiberglas Strep <br />Strap A/ <br />Eyelet <br />Galvanized <br />Steel �� T <br />F G <br />D <br />E --)- <br />Strap <br />►Strap Eyelet <br />Detail A <br />Tank Diameter <br />Nominal H D E F G <br />4' <br />21" <br />9/16" <br />13/8" <br />1 1/8" <br />2 1/16" <br />6' <br />34" <br />1 1/8" <br />2 7/8" <br />2 1/2" <br />4 1/4" <br />8' <br />38" <br />1 1/8" <br />2 7/8" <br />2 1/2" <br />4 1/4" <br />10' <br />52" <br />1 1/8" <br />2 7/8" <br />2 1/2" <br />4 1/4" <br />• All anchor straps must be uniformly tightened with turn- <br />buckles or come -a -longs. Straps should be snug, but not <br />cause tank deflection. <br />• Measure tank deflection by measuring tank diameter be- <br />fore and after snugging straps. <br />• Use standard nonmetallic gauge stick. <br />• See Installation Checklist for specific measurement in- <br />structions. <br />•Triple clamp wire rope. <br />• If deflection occurs, loosen straps to allow tank to go <br />back into round. <br />Note: Do not use straps between ribs! <br />(Exception 4' diameter tanks.) <br />Concrete Anchor Pad <br />The weight of the overburden on the concrete pad and tank <br />provides anchoring force. The anchor pad information pro- <br />vided below is strictly for buoyancy: <br />• Anchor Pad should be at least 8" thick, with #6 rebar at <br />12" on center each way. <br />• Poor soil conditions may require increased reinforcement <br />and anchor pad thickness.

The maximum bedding is 24". <br />• Attach anchor points to the ends of anchor straps with <br />turnbuckles or wire rope. <br />• Refer to Anchoring Hardware Section for hardware in- <br />formation. <br />• Triple clamp wire rope. <br />Deadman Anchors <br />• The weight of the overburden on top of the deadman and <br />tank provides the anchoring force. <br />• Deadmen are made with reinforced concrete (246 rebars <br />centered vertically). <br />7 <br />R <br />/Triple Clamp <br />l� <br />Bed <br />a o Minimum <br />Height <br />oo <br />#8 Rebar <br />o <br />o 00 <br />00 <br />14— Width <br />7 <br />
