Geological Instrument----JJC-1B Detecting System for Bored Concrete Pile

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 PIC SCM. It can display determination data and curves on time, and store and output for printing. It is convenient to make determination 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.
