The side surface of the projection plate 14 facing the infrared detection device 2 is kept flat.
The flat-surfaced projection plate 14 facilitates the emission of infrared rays, and also improves the accuracy of detection.
The position of the avoidance groove 21 corresponds to the positions of the first infrared distance measuring sensor 24 and the second infrared distance measuring sensor 27, the first infrared distance measuring sensor 24 and the second infrared distance measuring sensor 27 are aligned up and down, and the first infrared distance measuring sensor 24 and the second infrared distance measuring sensor 27 can penetrate through the avoidance groove 21 to irradiate onto the projection plate 14.

Since the first infrared ranging sensor 24 is located on the first reference plate 23, and the first reference plate 23 is immovable, the value measured by the first infrared ranging sensor 24 is a fixed value, which is used as a reference contrast; since the second infrared ranging sensor 27 is located on the second reference plate 26 and the second reference plate 26 is movable, the value measured by the second infrared ranging sensor 27 is a non-fixed value, and the magnitude thereof depends on the degree of uniformity of the reference surface. When the surface of the foundation to be measured is uniform and flat, the difference between the measured value of the second infrared distance measuring sensor 27 and the measured value of the first infrared distance measuring sensor 24 is zero; when the surface of the foundation to be measured is uneven, the difference between the measured value of the second infrared distance measuring sensor 27 and the measured value of the first infrared distance measuring sensor 24 is large, so that the flatness of the surface of the foundation after settlement can be rapidly judged.
