It is VITAL that personnel responsible for the
installation and use of Inclinometer Casing READ and
UNDERSTAND the manual, prior to working with the

1.1 Applications

®
Geosense QJ (Quick Joint) Inclinometer Casing is for use with inclinometer
systems for monitoring stability & movement of:-
•
Slopes
•
Embankments
•
Diaphragm & sheet piled walls
•
Deep foundations
•
Tunnelling operations
•
Piles
•
Pre-loads
•
Deep excavations
Manufactured from high impact virgin ABS material, it has four internal grooves formed at
90 degrees into the internal surface into which inclinometer probes (Portable or In-Place)
can be inserted to carry out profile monitoring of the casing which will deform with any
ground movement.
It is available in standard 3 & 1.5 metre lengths with QJ (Quick Joint) flush couplings at
each end which can be easily pushed together to provide a watertight self locking joint
while maintaining precise groove alignment and high collapse resistance.
®
Geosense QJ Inclinometer Casing can be installed vertically, inclined or horizontally in
boreholes, embedded in fill material, cast into concrete or attached to structures.

1.2 Advantages

QJ Inclinometer Casing requires no special tools, glues or rivets for installation resulting
in much faster installation, especially in deeper installations.
As it is flush coupled it can be installed in smaller boreholes and utilised in combination
with magnetic settlement systems.
