NOTE: WHEN THRUST BLOCK BEARING AREA IS NOT SPECIFIED ON THE PLANS OR DETERMINED BY THE ENGINEER, USE THE FOLLOWING PROCEDURE TO DETERMINE REQUIRED BEARING AREA.

1. Determine thrust (T) for type of fitting or joint and size of pipe from Table. 2. Determine Design (Test) Pressure from Standard Specifications or Special Provisions. 3. Determine Table Pressure from Table. 4. Determine Soil Bearing Capacity (B) of soil from Table. 5. Determine required bearing area (A) in sq. ft. as follows: A = Example: Design (Test) Pressure = 150 PSI From Table, T = 272.3 PSI Pipe = 14" From Table, B = 14 PSI Fitting = Tee Soil = Sand A =

GENERAL NOTES FOR ALL DETAILS:

1. Contractor to provide blocking adequate to withstand full test pressure.

2. Divide thrust by safe bearing load to determine required bearing area (A in sq ft) of concrete to distribute load.

3. Adjust bearing areas (A) for other pressure conditions. (See "Determination of Thrust Block Bearing Area" equation.

4. Pour concrete blocking against undisturbed earth.

5. All concrete shall be commercial grade concrete.

6. Wrap pipe and/or fittings with 2 layers of polyethylene film where in contact with concrete

7. Keep concrete clear of all joints and accessories.

8. Stirrups shall be deformed galvanized cold rolled steel AASHTO M31 (ASTM A615), Grade 60. Coat with coal tar epoxy after installation.

NOTE: All material and workmanship shall be in accordance with

the current Oregon Standard Specifications

1. When pipe is shorter than 18’, no joints allowed. Use mechanical joint retainer glands. Two 3/4 " galvanized tie rods may be used in lieu of thrust blocks for installations less than 18’ long. Coat tie rods with two coats of coal tar epoxy. 2. When pipe is longer that 18’ retainer glands not required. 3. There shall be a minimum of 18" horizontal clearance around hydrant. 4. When placed adjacent to curb, hydrant port shall be 24" from face of curb. 5. Concrete thrust blocks shall be constructed as per thrust blocking Std. Drg. RD250. Do not block drain holes 6. Extensions required for hydrant systems shall be installed to the manufacturer’s specifications. 7.
