Anchorage for11-1/4°, 22-1/2° & 45° Upper Vertical Bends

Concrete Notes:1) Fc=3000 PSI AT 28 DAYS.2) Carry all bearing surfaces to undisturbed earth or firm subgrade.3) The anchorage dimensions shown are based on design water pressure of 150 psi. Where a higher pressure specification is required, the volume of the concrete (L x W x D) shall be adjusted proportionally according to the design pressure used.

Reinforcing Bar Notes:1) Reinforcing Bars shall be hooked at each end and embedded minimum 8" into concrete. Exposed portion of all bars shall be painted with a minimum two coats of bituminous paint.2) Where 3 bars are used, they shall be arranged as shown on the detail above.3) Where 4 bars are used, 2 bars shall be located at each of end of the bend, symmetrically located on either side of the fitting.

Buttresses forTees, Plugs and Caps

Notes:1) FC = 3000 psi at 28 days.2) Buttress block dimensions are appropriate for design water pressure less than or equal to 150 psi.3) Where design water pressure exceeds 150 psi, block dimensions shall be proprtioned based on actual design pressure.4) All bearing surfaces shall be extended to undisturbed earth or firm subgrade.5) Tapping assemblies and sleeves shall be buttressed as comparably sized tees.
