In this paper,a pile hole size detection method based on laser radar technology is proposed.The ultrasonic sensor and inclinometer,which are mounted on the pendant of the anomaly detection device at the pile hole of the cast-in-place pile,are used to monitor and detect the inclination angle of the pile hole and the lifting rope,respectively.The pile diameter deviation and the verticality of the lifting rope are thus obtained,and an anomaly alarm is generated for deviation values exceeding the threshold.The technology is applied to a bored pile in a construction site,with good effect.
