Purpose:  

    It is mainly used to check the bore diameter quality of filling pile for the projects of high building, bridge, airport, high-way, seaport and wharf. Package may be used to detect the bore diameter, depth, vertical extend of bore, appearance of the borehole wall, and the dreg thickness on the bottom of bore. Main controller is made up of notebook PC and portable printer. It can display determinating data and curves on time, and store and output for printing. It is convenient to make determinating report. The system realizes digitization of quality determination for bore diameter detecting system for filling pile, it is the exchange product of the "JJC-1A",which has widely used. May improve the efficiency and quality of determination project.

     It has been widely used in architecture, communication, rail way and water conservancy in the past ten years.
