CONSTRAINTS
1. SOIL CONDITIONS AND BEARING CHARACTERISTICS ARE
TO BE DETERMINED BY THE CITY.
2. THIS STANDARD DETAIL IS FOR HORIZONTAL THRUST
RESTRAINT ONLY.
3. CONCRETE BLOCKING SHALL BE PER APWA SPECIFICATION
7- 11.3(13)1984.
4. CONCRETE THRUST BLOCKING FOR FITTINGS LARGER THAN
16' SHALL BE AS SHOWN ON THE PROJECT PLANS.
5. MAINTAIN 18" MINIMUM GROUND COVER OVER THE TOP
OF ALL CONCRETE BLOCKING.
6. WRAP FITTINGS WITH 8 mil THICK POLYETHYLENE
SHEETING PRIOR TO POURING CONCRETE.
PROCEDURE
1. DETERMINE BEARING FACTOR IN TABLE 1 CORRESPONDING TO
APPROPRIATE PIPE SIZE AND TYPE OF FITTING.
2. MULTIPLY THE BEARING FACTOR DETERMINED IN TABLE 1 BY THE
MULTIPLICATION FACTOR IN TABLE 2 FOR THE APPROPRIATE
SOIL CLASSIFICATION.
THE RESULT IS THE REQUIRED AREA OF CONCRETE (IN
SQ. FT.) WHICH MUST BEAR AGAINST UNDISTURBED SOIL.
3. USING TABLE 3 LOCATE THE MINIMUM DEPTH OF CONCRETE
(Dmin) CORRESPONDING TO THE REQUIRED BEARING
AREA.
4. USING Dmin, THE HEIGHT- D LENGTH OF THE THRUST
BLOCKING CAN BE DETERMI FROM THE DIMENSION
