Applications and Setups
This section describes three fundamentals for using the Model
DG813/613 to install gravity flow pipe; they are Grade, Elevation, and
Line otherwise known as G-E-L.
To install gravity flow pipe, the pipe is set to a percentage of Grade that
has been determined by some engineered plans. The gravity flow pipe is
designed to be set to some engineered Elevation. Finally, the gravity flow
pipe will be installed between two designed points, therefore defining
Line.
The process for setting up the Model DG813/613 remains the same. The
laser beam shall be sloped to match the plans. The Elevation of the pipe
or cut to invert is given from the plans at which the laser shall be used to
control that elevation, and finally set the laser on Line to match the
orientation of the pipe run.
After all have been set, installing pipe is accomplished by inserting a laser
target into new pipe sections and then aligning the pipe until the laser
target’s bulls-eye is centered on the beam.
