Engineering Investigation
Engineering Survey: Widely used in geotechnical investigations for railways, bridges, and urban projects, as well as archaeological surveys and underground pipeline detection, supporting both detailed and preliminary exploration.
Geological Survey: Applied in detecting mined-out areas, groundwater hazards, dam risks, fault zones, collapse columns, and slope instability, for both detailed and regional hydrogeological investigations.
The system is equipped with a self-developed APP based on the Android operating system, providing high levels of intelligence and smooth interaction. It is compatible with most Android and HarmonyOS devices, including smartphones, tablets, and the company’s professional intelligent control hosts. From parameter settings and data collection to mapping and imaging, the entire process is visually guided, greatly reducing reliance on operator experience and providing efficient and convenient support.
The system adopts the latest circuit design, combining automatic noise reduction with analog and digital filtering. It effectively extracts weak, real signals even in high-interference environments, ensuring that the data collected is stable, pure, and repeatable. This provides a solid foundation of trust for your decision-making.
The system simultaneously acquires multiple parameters such as VP, IP, SP, RO, M, TH, Z, and D. It also supports polarization decay curve results. The cross-validation of multiple parameters significantly reduces ambiguity in geological interpretation, making the judgment of subsurface anomalies more accurate.
The system features a lightweight design for easy field transport. It includes ten different mode types, such as four-electrode depth measurement, intermediate gradient, and joint profile. The system is adaptable to various tasks, from profile scanning to 3D area exploration, allowing a single device to handle a wide range of scenarios.
The system can be paired with a line-borrowing remote control system, easily upgrading to low-density, deep-exploration configurations. The device’s capabilities can grow alongside your business, effectively protecting the initial investment while meeting future, more demanding exploration challenges.
