Background
In the building engineering, the air in the original wall and the plaster layer can cause hollowing, particularly, hollowing phenomena can easily occur between the ground, the wall surface and the ceiling decoration layer and the structural layer in a house due to adhesion and infirm combination, and although the hollowing phenomena can not cause the stress quality problem of the house, the phenomena such as peeling of the wall skin, bubbling and the like can be caused after the time is long, so that the building is quite unattractive.
The existing tool for detecting the hollowing is usually manually knocking the ground or the wall surface through a knocking hammer, if the wall surface or the ground is provided with the hollowing, a 'clattering-noise' sound can be heard, so that whether the wall surface is hollowing or not is judged, but the mode has the following defects:
1. when the hollowing detection of the wall surface is carried out, a detector can knock a higher place on the wall surface by using a ladder, and when the ladder is placed once, the detection range of the detector is only in a circular area formed by taking the body of the detector as the center and taking the length of an arm as the radius, so that when the wall surface is detected once, the detector is not required to continuously climb the ladder underground, move the ladder and then climb the ladder, and the wall surface hollowing detection device is very labor-consuming and extremely low in efficiency;
2. when the bottom surface is knocked, a detector needs to bend down or squat on the ground, and continuously moves the body of the detector to an area which is not detected along with the knocking position, so that the workload is very large.
