Multi-source scanning type cast-in-situ bored pile expanded head contour scanning device and method

Abstract

The invention discloses a multi-source scanning type cast-in-situ bored pile expanded head contour scanning device which comprises a depth encoder and an in-hole probe, and an upper shell and a lower shell of the in-hole probe are connected through a calibration communication rod. A conical surface reflection type fixing support, a laser scanner, a sonar scanner and a conical reflector are sequentially installed below the upper shell, a liquid sensor is installed above the lower shell, and an electronic compass and a camera are sequentially installed above the liquid sensor. The upper shell is connected with the industrial personal computer through a transmission tension cable and a depth encoder in sequence. The invention further discloses a multi-source scanning type cast-in-situ bored pile expanded head contour scanning method, the problem of high-precision measurement of the cast-in-situ bored pile hole expanded head is solved, and three-dimensional visual visualization of the cast-in-situ bored pile hole expanded head is synchronously achieved. The method and the device are novel in conception and easy to implement, are a new method and a new-generation device of the technology for measuring the expanded head of the cast-in-situ bored pile, and have wide application prospects.
