8.0 INSTALLATION - VERTICAL FILL
Inclinometer Casing is often installed in vertical fills such by adding lengths of Casing as
the filling progresses for applications such as embankments and dams.
It is recommended to use 1.5m lengths for this application.
In these applications settlements are expected and the use of telescopic joints or a
corrugated external sleeve (see GXM-300) should be used.
Joining of the Casing is generally as shown in section 7.0.
A typical installation procedure is as follows:-
8.1 Excavate a small pit or drill a shallow borehole into solid ground.
8.2 Fit the bottom cap to the first length and place into the pit/borehole.
8.3 Check for verticality
8.4 Backfill with grout.
8.5 Once grout has set carefully place finely graded selected fill and compact manually
taking care not to damage the Casing or affect its verticality.
8.6 Where necessary place telescopic joints.
8.7 Continue adding lengths of Casing and fill as required.
ALWAYS PROVIDE PROTECTION TO AVOID DAMAGE OR CHANGE IN
VERTICALITY
