GT-30 Geotech model

The GT-30 Geotech model of the transient electromagnetic instrument is a transient electromagnetic instrument device developed and manufactured by Shenzhen Saiying Ground and Air Technology Co., LTD. This model is mainly applied in scenarios such as urban engineering investigation, underground pipelines, underground cavities, and dam leakage

Product Features

1

Small in size, light in weight and convenient for construction. The receiver is a flat plate made of light metal material, which is lightweight and easy to carry, and features touch screen operation. Sturdy and waterproof.

2

The coplanar equivalent anti-flux transmitting and receiving integrated coil is easy and convenient to operate, and it also has the ability to detect large depths without blind spots.

3

High performance and low power consumption. The CPU is equipped with a 2.24ghz quad-core processor and a 32-bit AD conversion chip, featuring no operation delay, high measurement accuracy and wide dynamic range.

4

Our self-developed technology overcomes the "blind spot" problem inherent in transient electromagnetism, enabling effective ultra-shallow detection and precise measurement of shallow anomalies as shallow as one meter.

5

Advanced interpretation and processing software system. A full-space interpretation software system for underground work (such as underground tunnels, shafts, etc.), with user-friendly operation, one-click filtering and one-click mapping.

6

Universal transient electromagnetic receiver, which can be matched with different transmitters and coils, meets the requirements of transient electromagnetic detection in explosion-proof environments in underground coal mines, advanced prediction of tunnels and surface environments.

7

It can be interconnected with the online processing and interpretation system for advanced detection data to achieve real-time upload, storage, interpretation and mapping of geophysical exploration data.

Application direction

Engineering inspection

Detect geological diseases such as voids, fractures, karst and weak layers in the subgrade and base of expressways, airport runways, urban roads and railway and highway tunnels;

Detect potential safety hazards such as leakage, voids and ant holes in the foundations and bodies of reservoirs, river-blocking DAMS, tailings DAMS, etc.

Engineering investigation

Detect shallow karst and evaluate the scale, morphology and water content of karst, etc.

Determine the scale, occurrence and water content of the shallow fracture zone, etc.

Detect the three-dimensional characteristics such as the distribution range, burial depth and occurrence state of shallow goaf areas;

Exploration of permafrost layers, the thickness, burial depth and other occurrence characteristics of permafrost layers;

Metal ore exploration

Rapidly evaluate the mining rights prospects of metal mines, explore the scope and occurrence of metal ore bodies;

Others

In archaeological research, explore the distribution range and burial depth of ancient tombs;

Detection of metal products in ancient tombs in archaeological research;

Functions

The GT-30 is mainly applied in urban engineering investigation, ultra-shallow investigation of urban road voids, pipelines, etc., and has strong anti-interference ability. As well as dam seepage, ant holes and cavities, etc.
