(4) When the pole has sunk to the desired depth, shut off the water and remove the hose.
(5) Face and straighten the pole.
(6) Fill the hole with the overflow of sediment around the pole. Tamping of this backfill is
usually not necessary. The detailed plans will specify the type of swamp fixture that may be necessary
to hold the pole permanently erect.
PART D - RAISING AND SETTING THE POLE
Pole derrick method. Setting poles by means of a truck-mounted derrick is the simplest and
safest method in most cases. (See Figure 1-4.) The boom of the earth borer can also be used as a pole
derrick. The boom must not be subjected to any appreciable lateral strain. This method will be used to
set poles which do not exceed 45 feet in length.
