this situation, it is generally measured with following methods:
1)
To locate stirrups.
2)
To select a scanning line in the middle of large space
stirrups.
3) To select one direction for scanning and mark the
rebar location.
4)
To scan for a second time in reverse direction and
mark the rebar location.
5)
If the two scan results are same, the measurement is
over.
6)
If not, repeat the step 3 and 4. If the two sets of
measurement are in line with following features: the
first scanning can determine A, B and C rebar, then in
reverse direction, D, C and B will be identified.
Therefore, almost certain that there are 4 steels in this
object.
Figure 3-38 Dense rebar measurement
2. Minimum thickness of cover measurement
It is mainly used for following situations:
1)
After removal of moulding board, to test whether rebar is out or
not.
2)
Quick check of whether thickness of cover meets the minimum
