Remove the protective cap from the access tube. Disengage the threaded adaptor from the
casing end cap.
2.20
Connect and fix the dummy probe to the threaded adaptor and other end to the operating cable
to pull the probe through the access casing.
2.21
Pass dummy probe to check the correctness of casing jointing after assembling casings of 3 m
each.
NOTE:
Make sure to pass the SS pulling wire through the casings while assembling the same. This
wire shall remain permanently inside the access casing to facilitate pulling of dummy and
main probes.
2.22
Secure the jointed casings on the marked alignment either using a tie wire or nylon cable ties to
the reinforcement cage/horizontal borehole. This securing is essential as the casings might get
shifted in any random direction during pouring of concrete.
NOTE:
Maintain one pair of groove parallel to the horizontal
plane/surface. This would ensure that the major set of groove,
which shall be used for passing the inclinometer probe, is
perpendicular to the base slab. Maintain this orientation all
through the casing alignment.
CAUTION:
Ensure that the orientation of major set of groove remains
perpendicular to the base slab, right from the first casing laid, to
the last one, at the other end of the alignment i.e. it should be maintained perpendicular all
across the diameter of the base slab. This is essential to get correct data.
NOTE:
Prolonged exposure of casing to direct sunlight should be avoided. During assembly,
casings yet not covered under concrete shall always be kept covered with a vinyl cover to
protect from direct sunlight. It should also be protected against any type of impact during the
installation process.
2.23
Keep the ends of the casings covered by using the special protective caps provided. Cover the
ends during the assembly process- if the tubing is being left unattended.
NOTE:
Make sure that during pouring of concrete on the base slab, concrete is not poured directly
over the access casings. This might distort or even damage the casings.
2.24
Flush inside of casing with clean water after concreting. This will wash away any type of dirt,
debris, concrete sap, rivet heads etc.
NOTE:
It is recommended to again flush the hole with water just before commencing the
monitoring. Also pass a wooden ‘dolly’ to check for seepage of concrete sap, if any.
