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.
