5.2 End caps
Before installing the
QJ Inclinometer Casing
a bottom
cap should be fitted. Various options are available as
follows:-
5.2.1 QJ standard end cap (A)
To be used where no problems with uplift are expected
and a separate external Tremie tube is to be used.
5.2.2 QJ grout valve cap (B)
Used in small boreholes where there is no room for
external Tremie pipes.
The cap has a non-return valve and perforated pipe
fitted to the end cap (1).
The grout pipe fitted on the bottom with a female
Quick-Connect coupling (2) is lowered through the
inclinometer Casing and couples to a male
Quick-Connect coupling (3) in the cap.
Grout is pumped through the pipe into the base of the
borehole filling it from the base.
The grout pipe is removed after grouting completed.
