  • Technical Specification

JJC-1EG Detecting System for Borehole Concrete Pile is a kind of special equipment for detecting the pore-forming quality of bored piles. It goes through the development of JJC-1A, JJC-1B, JJC-1C and JJC-1D. It takes the construction environment and requirements on site into consideration, being easy for operation and having a higher accuracy.

This system is composed of model JJC-1EG control case, model JJY-6 caliper /inclinometer measuring probe, model JNC-2 sediment/inclinometer measuring probe, model JC-100 automatic cabling winch, pulley and so on.
