Digital Pile Caliper Detecting System for Borehole Concrete Pile Diameter Measuring Equipment
GDC-1EG Detecting System for Borehole Concrete Pile
GDC-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 GDC-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.
This system is developed base on mode JJC-1D detecting system. It has characteristics:
- The measuring probes underground are totally digitized.
- The measuring probes underground are stainless steel materials.
- Equipped with a automatic cabling winch.
- The caliper/inclinometer measuring probe and sediment/inclinometer measuring
- The hole diameter measuring bias reduces to 5mm.
- The control case adopts industrial computer, it is easy to operate and has strong anti-interference ability, it also can judge the model of the probe underground automatically.
- The operation software is suitable for WIN XP/WIN VISTA/WIN 7.
- It is the upgrading product of JJC-1D which is accepted and popular among the customers. It improves the work efficiency and quality.
