Referring to fig. 2, grouting holes 2 are distributed above the grouting joints 1 of the bin body, exhaust holes 3 are distributed above the grouting holes 2, and the ultrasonic testing probe moves along a preset scanning direction.
It should be noted that, the number of the exhaust holes is plural, and only one exhaust hole needs to be selected arbitrarily to inject compressed air, and other exhaust holes and grouting holes are plugged for testing, and the test is performed without injecting compressed air into each exhaust hole one by one.
