CONCRETE BLOCKING SIZING PROCEDURE
A. %IENEMI
The amount of concrete required. to am Uor hcP,IZtsl ►ends, tees,
and dead ends depends on the strength o/ [ha sett (_ TM se[bN of
placing concrete to keep the Joint accessible Is shorn In Figure I.

of the [ranch is found by dtvidi nq the thrust In pounds sMwn In
Table 1 by the safe Mari ng load of the soil as show. In Table 2.
B. CRITERIA
I. Thesizing procsdure, is for horizontal or dowrwerd thrust only.
Z. Might of the thrust block must be equal to or Isms than 1/2
the death from the around surface to the block base.
3. The thrust block bearing face is approximately rectangular.
4. The concrete blocking shall be as per A►VA Specification 74-2.14.
