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 000inst the side of the trench is found b dividing the thrust in pounds shown in Table 1y by the safe B. RI A bearin food of the soil as shown in Table 2. 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. he concrete blockingg shall be as per APWA -5YM,Secification 74-2.14.

Maximum Length of Thrust Block (Lm) = Area of Concrete - A Maximum Height Hm 5. Required Amount of Concrete (Cu. Yd.) = (Height x Depth x Length) x 0.03704 = (Hm x Lm x Dc) x 0.03704 E. EXAMPLE 1. 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 psi. = 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 see that the thrust on a 90' bend is 21,360 pounds. D - 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 = 712 sq ft. Safe Bearing Load 3,000 - Maximum Height of Thrust Block (Hm) = Depth of Trench in Feet 2 h 4 = 2.0 ft. 2 2 - Depth of Concrete Thrust Block (Dc) Width of Trench in Feet (W) - Outside Diameter of Pipe (d) 2 _ 3-0.75 = 1.13ft. 2 Maximum Length of Thrust Block (Lm) Area of Concrete Height of Concrete = A _ 7.12 = 3.56 ft. Hm 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.

Joint Restrainer System Components: Installation: Install the joint restraint system in accordance with the Manufacturer's instructions so all joints are mechanically locked together to prevent joint separation. Tiebolts shall be installed to pull against the mechanical joint body and not the M.J. follower. Torque nuts at 75-90 foot pounds for 3/4" nuts. Install tiecouplings with both rods threaded equal distance into tiecouplings. Arrange tierods symmetrically around the pipe. Where a Manufacturer's mechanical joint valve or fitting is supplied with slots for "T" bolts instead of holes, a flanged valve with a flange by mechanical joint adaptor shall be used instead, so as to provide adequate space for locating tiebolt. Where a continuous run of pipe is required to be restrained, no run of restrained pipe shall be greater than 60 feet in length betwee fittings. Insert long body solid sleeves as required on longer runs to keep tierod lengths to the 60 foot maximum. Pipe used in continuously restrained runs shall be mechanical joint pipe and tiebolts shall be installed as rod guides at each joint. Where poly wrapping is not required, all tiebolts, tienuts, tiecouplings, tierods shall be galvanized. All disturbed sections will be painted, to the inspector's satisfaction, with ATCO #2221, or approved equal. Where poly wrapping is not required, all tiebolts, tienuts, tiecouplings, tierods, and tiewashers may be galvanized, as specified above, or plain and painted in their 4-97 EDIT TEXT DCV DT DATE REVISION BY APPR'D SURVEYED: - DESIGNED: J.E.
