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 Il by the safe bearingloadof the soil as shown in Table 2. B. 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 concrete blocking shall be as per APWA SYMBOLS Specification 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. (Table 2) h = Depth of Trench in Feet W = Width of Trench in Feet A = Area of Concrete which must bear against the Side of the Trench in Sq. Ft.

Problem Calculation of the amount of concrete required to block a 90' bend in an 8" C.I. water main; the normal operating pressure in the pipe will be 65 psi and the soil condition in the area indicates sand and gravel. 2. Solution: - Maximum testing pressure (See Table 1) = 300 psl. = 0,75 ft. - Outside diameter of 8 pipe = 9.05 in. = 9.05/12 - Go to Table 1: The testing pressure of 300 psi, we sPe that the thrust on a 90' bend is 21,360 pounds. 1 /4" EDGED GROOVE / 0.02 FT/FT WWF 4" CEMENT CONCRETE SIDEWALK 2" CRUSHED ROCK BASE VARIES NO : 1. CEMENT CONCRETE SHALL BE CLASS B. 2, DUMMY JOINTS CONSISTING OF 3/16" BY 2" PREMOLDED JOINT MATERIAL SHALL BE PLACED AT 15 FOOT INTERVALS. - Go to Table 2: Table 2 gives the safe bearing load for sand and gravel: 3,000 lbs./sq, ft. - Go to Figure 1: figure 1 indicates the position of the concrete for blocking the 90' bend. - Go to the specifications of the project and find depth of trench (h) = 4 feet - Width of trench (W) = 3 feet With the above assembled information, we proceed to the final calculations: - Area of Concrete (A) = Thrust = 21,360 = 7,12 sq ft. Safe Bearing Load 3,000 Maximum Height of Thrust Block (Hm) = Depth of Trench in Feet 2 h 4 2 = 2 = 2.0 ft, - Depth of Concrete Thrust Block (Dc) Width of Trench in Feet (W) - Outside Diameter of Pipe (d) 2 3-0.75 =1.13ft. 2 Area of Concrete - Maximum Length of Thrust Block (Lm) = Height of Concrete A Hm _ 7.12=3.56fL _ 2.0 - Required Amount of Concrete = (Height x Depth x Length) x 0.03704 = (Hm x Lm x Dc) x 0.03704 = (2.0 x 3.56 x 1.13) x 0.03704 = 0.30 cu. yd.
