摘要
仪器采用双滚筒双排缆绞车及其带绕双根四心铠装电缆，通过双滑轮架井口导问，并定向吊放井下仪器，进行井内检测。其基本原理是利用超声波测距原理，结合计算机等综合性科学检测技术，实现大口径基桩孔的成孔质量检测，即检测其孔径、孔斜和孔底沉碴厚度。
This monitor is equipped with double drum,bicable houble piece and double piece and quardruple corearmored cable and is put down into the hole through the orientation of a double-pulley-racl. Its basic principle is combining uttrasonic distance measuring theory with comprter and comprehensive scientific monitoring technology,to execute quality inspection of large diameter foundation pile hole ;that is to monitor hole diameter,inxlination and the thickness of downhole cuttings sediment.
