GENERAL The amount of concrete required to anchor horizontal bends, tees, and dead ends depends on the strength of the soil. The methods of placing concrete to keep the joint accessible is shown in Figure 1. The area in square feet of concrete which must bear against the side of the trench is found by dividing the thrust in pounds shown in Table 1 by the safe bear* load of the soil as shown in Table 2. B. SiI3ilERIA 1. The sizing procedure is for horizontal or downward thrust only. 2. Height of the thrust block must be equal to or less than 1 /2 the depth from the ground surface to the block base. 3. The thrust block bearing face is approximately rectangular. 4. The e concrete blocking shall be as per APWA SYM pacification 74-2.14. C. d = Outside Diameter of Pipe in Feet T = Thrust in Pounds at the Fitting (Table 1) SBL = Safe Bearing Load in Pounds/Sq. Ft.
