PJC8000 Geological Radar - Municipal Pipeline Detection and Environmental Protection Hidden Pipe Location, equipped with a 25-1200MHz stepped frequency antenna, can achieve full depth coverage of 0.5-8 meters without replacing hardware - cracks as shallow as 10cm on the road base, and caves and goaf areas as deep as 8 meters can be accurately detected. In the exploration of karst areas in Southwest China, PJC8000 penetrated a 6-meter thick clay layer and clearly identified underground caves with a diameter of 1 meter, which increased the coverage area by 60% compared to traditional equipment (detection depth ≤ 5 meters).

The PJC-8000 series ground penetrating radar is centered around advanced ultra long pseudo-random coding and ultra wideband antenna technology, and adopts a fully digital design controlled by software to achieve all the functions of a general ground penetrating radar. It also adds functions such as wireless transmission, hardware and software filtering, time-varying gain, software delay, software adjustable sampling, standard IEEE802.11 communication protocol, GPR parameter automatic setting, etc., making it more convenient to use without adjustment. At the same time, the PJC-8000 series wireless ground penetrating device is a system with wireless data transmission function, which can use any device with WLAN function as display, processing, and storage, such as laptops, iPads, and even mobile phones, with a continuous working time of more than 15 hours.


The geological and hydrological conditions in tunnel construction are complex, with many unforeseeable factors, and the main part is concealed engineering, making it difficult to inspect the quality of the project. Due to the advantages of intuitive abnormal images, high work efficiency and resolution of ground penetrating radar method, this method can be applied in short distance (15-60m) prediction, tunnel quality inspection, and retaining wall disease detection in advanced geological prediction of tunnels. It provides a basis for tunnel excavation and support design and construction, and proposes construction suggestions for dynamic tunnel construction to reduce construction blindness, ensure construction quality, progress and safety, and reduce project costs.
