Installation
Tape Extensometer
Reference points consist of eyebolts that are secured directly to a
structure or threaded into a groutable or expansion anchor. They
should be positioned to reveal the magnitude and direction of move-
ments. Initial alignment is not critical, because the hook and eyebolt
system can accommodate almost any tape angle. It is important to
protect the eyebolts once they are installed, since any change in their
position or condition will affect the repeatability of
measurements.
Groutable Rebar Anchors
1
Drill hole for anchor. Grout anchor in hole using non-shrinking
grout. Allow time for grout to set.
2
Thread a spare eyebolt into the anchor and pull-test to 130
newtons (30 lbf). If there is no measurable movement, remove the
spare eyebolt.
3
Thread a lock nut onto the eyebolt, and then thread the eyebolt
into the anchor. Tighten the lock nut.
Expansion Anchors
1
Drill hole for anchor. Adjust anchor to fit hole, then insert until
setting bolt is slightly below rock face. Tighten anchor to refusal
point.
2
Thread a
spare
eyebolt into
the anchor
and pull-test
to 130
newtons
(30 lbf). If
there is no
measurable movement, remove the spare eyebolt.
