| CONTINUOUS FLIGHT AUGER
The continuous flight auger consists
of a hollow stem with flighting which extends the full
length of the stem. This tool is used to install continuous
auger cast piles by drilling the tool to required depth
and withdrawing the tool while inserting grout into
the resulting shaft.
This tools is usually mounted on a top drive drill
rig with an integral computer system which controls
the grout input to match the stem withdrawal to insure
complete filling of the drilled hole.
