measurement method
for the plate under test, Measure whether there is exposed
reinforced, through type (, frosting) between the sight
distance of about 0.5m; use steel ruler to measure the length,
dimple hole, missing angle data of the plate surface crack
key, read to 1m, enlarge the scale slowly to measure the
width of the crack key, and record the number of blocks
6.3.1 measuring tool
steel tape precision 1mm vernier caliper 0 ~ 150mm;
Accuracy of steel ruler is 0.5mma, internal and external error,
feeler gauge is 0 ~ 10mm, guiding rule is 2m
6.3.2 measuring method
6.3.2.1 length
measuring three places
one plate edge two places: within the range of 100 mm near
two plate edges, parallel to the plate edge
one place in the plate: passing through the midpoint of two
plate ends, as shown in Figure 2
