Correct Direction
Correcting direction is a skill operators gain with experience and knowledge of equipment and soil
conditions. These instructions cover only basic procedures. For information about specific equipment or
jobsites, contact your Ditch Witch
®
dealer.
To track progress and make corrections, one crew member locates the drill head and sends instructions to
the operator. Corrections are made by tracking the drill head, comparing current position to bore plan, and
steering drill head as needed.
Basic Rules
•
Steering ability depends on soil condition; bit, drill head, and nozzle used; roll of drill head; and
distance pushed without outer rotation.
•
All corrections should be made as gradually as possible. See “Recommended Bend Limits” on
•
Over correcting will cause “snaking.” This can damage pipe and will make drilling and pullback more
difficult. Begin to straighten out of each correction as early as possible.
•
Do not push an entire piece of drill pipe into ground without rotation. This can exceed bend radius and
cause pipe failure.
Procedure
1.
When drilling has stopped/paused, locate drill head. Take readings available with your beacon and
locating equipment such as:
•
depth
•
pitch
•
left/right information
•
temperature
•
beacon roll
2.
Compare position to bore plan. Determine direction drilling should go.
3.
Position drill head.
4.
Push in drill pipe as needed to change direction.
5.
Rotate in remaining length of drill pipe.
