This invention relates to the field of pile foundation testing, and more particularly to a pile foundation testing device and method for civil engineering construction. The device includes a tamping apparatus for testing the pile body and testing components. In this invention, when the pile body tilts, the light spot undergoes vertical and / or lateral displacement on the receiving plane. If the tilt causes the light spot to move upward or downward, it may partially or completely enter the light aperture range of adjacent adjustment apertures. For example, when the top of the pile tilts to the right, due to the clockwise rotation of the transmitting end, the projection point of the 45° beam moves upward on the receiving end plane. The light spot originally illuminating the middle adjustment aperture may simultaneously cover the edge of the light aperture of one or two upper adjustment apertures. If the tilt angle is large, the center of the light spot may completely move out of the original aperture and into the adjacent aperture area, or even cross multiple apertures. Therefore, the tilt amount of the pile body can be determined by monitoring the number of infrared receivers that have sensed infrared radiation.
