3 INSTALLATION PROCEDURE
2.1
Mark the alignment with the help of surveying equipment over the base slab reinforcement cage
or where the inclinometer access casing has to be laid. This alignment has to be a straight line
passing through the centre point of the structure and close to horizontal.
2.2
In a clean work area, collect all material to be
installed along with the required accessories.
2.3
Make sure to clean the casing ends before
inserting the same inside the fixed coupling. Also
make sure that the inside surface of the casings
is free of any dirt/debris while jointing.
2.4
Install the casing with one pair of grooves
oriented vertically, such that there is a top groove
and a bottom groove. Make necessary
arrangement (use of wooden packing etc.) to
make the alignment horizontal wherever
required.
2.5
Mark the outside of each casing as the top
groove and start assembling.
2.6
Pass the threaded adaptor of pull cable reel
through the first access casing (pull cable end)
and coupling.
NOTE:
The pull cable is to pass through all the
consecutive casings and couplings to be
connected.
2.7
Insert casing into the coupling after matching the
access casing ridge to the grooves inside the
fixed coupling. Insert all the way to the central
collar inside the coupling. The casing will stop at
the collar. Ensure not to leave any gap between
the ends of the two casings inside the fixed
couplings. Repeat the same procedure for the
other casing also.
NOTE:
If there is a gap between the two access
casings inside the fixed coupling, the
inclinometer probe wheels are likely to get
stuck in the gap at the time of monitoring.
Pulling out the probe with great force will
lead to loss of calibration/damage of its
sensor as these are sensitive to shock.
