THE GROUT LINE
nary experience proved to be reliable
with good and dependable results
comparable with the results obtained
with a “conventional” system.
The apparatus was practical to use and
did not cause any delay in the execu-
tion of the tests simultaneously with
the “conventional” system (despite
the initial doubts of the contractors
involved in the tests). The level of
the data presentation and analysis can
elevate the standard of the testing of
micropiles and anchors considerably.
An additional
advantage, subject
to further study by
the writer, is that the
instrument can be
used for long term
monitoring tests in
order to understand
the behaviour of the
micropile/anchor
in say, 1 day -or more- test, without
unnecessary waste of resources and it
can be economically advantageous.
Additional research and testing of
small discrepancies between displace-
ment data and pressure recorded shall
be carried out as “work in progress”.
A final question to the participants of
the workshop: Can the level of QA/
QC in the micropile/anchor industry
be increased using simple devices
which can also simplify the life of
Engineers and contractors?
