CONCRETE BLOCIONG SIZING PROCEDURE A. GENERAL The amount of concrete required to anchor horizontal bends, tees, and dead ends depends on the strength of the soft. 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 skis of the trench is found by dividing the thrust In pounds shown In Table i by the safe bea___riny_load of the sell as shown in Table 2- B. S.BlIE61A 1. The sizing procedure Is for horizontal or downward thrust only. 2 Height of the thrust block must be equal to or le® than 1/2 the depth from the ground surface to the block bass. 3. The thrust block bearing face In approximately rectangular. 4. The concrete blocking shall be ae per APWA SYMBOLS _ Specification 74-2.14.
