Drill Pipe and Equipment
1.
Assemble at least 20’ (6 m), but not more than
30’ (9 m), of drill rod.
2.
Install drill bit to the cutting end of the drill string.
3.
Put drill string in approach trench.
4.
Move tractor to the approach trench and align the drilling attachment with the intended bore path.
5.

IMPORTANT: The approach trench should
be at least:
•
deep enough for pipe to lay flat and
enter soil at correct angle
•
20’ (6 m) long
•
4” (100 mm) wide
IMPORTANT: The actual length of the target trench depends on soil conditions and length of pipe
sections. Make it deep enough for drill bit to enter slightly above the trench floor.
NOTICE: More than 10-15’ (3-4.5 m) of drill
rod out of the trench increases the
tendency of drill rod to bend.
