CONCRETE BLOCKING SIZING PROCEDURE
A. 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
bearing load of the soil as shown in Table 2.
B. CRITERIA
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
Specification 74-2.14.
C. SYMBOLS

1. Problem:
Calculation of the amount ofconcrete 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.
- 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:

- Required Amount of Concrete = (Height x Depth x Length) x 0.03704
