Abstract

The invention discloses a multi-source scanning type bored pile enlarging head contour scanning device, comprising a depth encoder and an in-hole probe. The upper shell and the lower shell of the in-hole probe are connected by a calibration communication rod, and the upper shell The bottom of the body is sequentially installed with a conical reflection type fixed support, a laser scanner, a sonar scanner and a conical reflector, a liquid sensor is installed above the lower shell, and an electronic compass and a camera are installed above the liquid sensor in sequence. , the upper shell is connected with the industrial computer through the transmission tension cable and the depth encoder in turn. The invention also discloses a multi-source scanning method for contour scanning of the enlarged head of the bored pile. The invention solves the problem of high-precision measurement of the enlarged head of the bored pile, and simultaneously realizes the three-dimensional measurement of the enlarged head of the bored pile. Intuitive visualization. The method and the device are novel in conception and easy to implement, and are a new method and a new generation device of the enlarged head measurement technology of bored piles, and have broad application prospects.
