Entry Pitch
Entry pitch is the slope of the drill frame compared with the slope of the ground. Determine entry pitch one
of two ways:
1.
With Pitch Beacon
•
Lay pitch beacon on the ground and read
pitch.
•
Lay pitch beacon on drill frame and read pitch.
•
Subtract ground pitch from drilling unit pitch.
2.
With Measurements
•
Measure from the ground to front end of drill
frame (H1).
•
Measure from the ground to back end of frame
(H2).
•
Subtract (H1) from (H2). Record this number.
•
Measure the distance between front and back
points (C).
•
Divide (H2-H1) by (C), then multiply by 100.
This is your pitch.
Minimum Setback
Setback is the distance from the entry point to where
pipe becomes horizontal (B1).
IMPORTANT:
A shallow entry pitch (A1) allows you
to reach horizontal sooner and with less bending.
Increasing entry pitch (A2) makes bore path longer
and deeper.
NOTICE:
If setback is too small (B2), you will
exceed bend limits and damage the pipe.
