A multi-source scanning type bored pile expanding head contour scanning device and method

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.

Description

technical field [0001] The present invention relates to the field of quality detection and measurement of the hole-forming quality of the data bored-in-situ pile, in particular to a multi-source scanning type bored pile expansion head contour scanning device, and also to a multi-source scanning type bored-in-situ pile expansion head contour scanning method It is suitable for the detection and measurement of the expansion head in the borehole of the cast-in-place pile in various engineering fields, to obtain the geometric shape and surface image information of the expansion head, and to realize the accurate measurement and three-dimensional visualization of the expansion head in the dry hole and wet hole environment. Background technique [0002] The rapid development of my country's economy has driven the rapid development of my country's construction industry. The deepening of foundation problems and the significant increase of deep foundation pit projects have also increas...
