[0002] The facing layer of the outer wall of a building is often affected by various factors and will often produce a hollowing phenomenon, which seriously endangers the load-bearing capacity and durability of the building. The current detection methods for the hollowing of the facing layer of the outer wall of a building mainly include visual inspection, hammering and pulling. The visual inspection mainly relies on the experience of the inspector for subjective judgment, and the accuracy is difficult to guarantee. The pulling method is a destructive test, and the sample size is small, lacking representativeness and pertinence. The detection also needs to set up a scaffold or a basket, and the operation is greatly limited, and the efficiency is low. The hammering method is to knock the facing layer and listen to the frequency reflected by the surface of the knocked facing layer to judge the internal defects of the facing layer.
