The other is a single-sided detection detector, which detects the thickness of the concrete by attaching the detector to the concrete layer. However, in the actual use process of the single-sided detector, there are still some deficiencies, one is that the single-sided detector cannot well detect the thickness of the concrete at different height positions when working; two is that when detecting the thickness of the concrete at a high position, the detector at the high position cannot be quickly adjusted in angle according to the slope of the wall; three is that when detecting the ground or the high wall with slope, when multiple positions need to be detected, the position of the detector needs to be constantly adjusted, and the detector needs to be held or lifted to move, which is more troublesome, time-consuming and laborious, greatly increases the labor degree, and the overall adaptability is poor.
