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
SYMBOpSpecification 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.
Hm = Maximum Height of the Thrust Block in feet
Dc = Depth of the Concrete Thrust Block

Lm = Maximum Length of the Thrust Block in Feet

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.
- 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 = 3 feet
With the above assembled information,
we proceed to the final calculations:
Thrust __ 21,360
Area of Concrete (A) = Safe Bearing Load 3,000 = 7.12 sq ft.
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
Maximum Length of Thrust Block (Lm) = Area of Concrete
Height of Concrete
= A _ 7.12 = 3.56 ft.
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.
