Geo Detection Ground Penetrating Radar

Share to:
TBT-GPR is an powerful addition to the utility surveyor’s toolkit which displays an image map of underground features and help the technician see a pipe or cable in itstopographical context that granting it ideal for locating and excavating utilities. Comparing with traditional electromagnetic locator TBT-GPR can see non-conductive materials including plastic pipes.

Application:

TBT-GPR is used to detect or identify the information of metal or non-metal targets in a certain depth underground for such as engineering surveys, municipal pipelines, roads bridges and tunnel inspections

1, Engineering survey: identify the information of bad underground geological bodies such as karst, collapse, broken zone, etc.

2, Municipal pipelines: identify the distribution of underground metal or non-metal pipelines in the process of urban construction.

3, Tunnel inspection: used for tunnel forecasting, tunnel construction quality inspection, etc.

4, Road and bridge: make geological body survey for road or bridge siting process. The geological radar can detect all kinds of pavements showing the thickness of each layer but without layer material details, the Radar distinguish the interface of different layers according to the dielectric constant of each layer of materials.

Relative Service:

Provides multi-parameter verification of spectrum induced polarization for detection abnormality at a certain depth.


Main features:

1, Optional multi-band antennas allows wide application range. This Radar acquisition system can be formed as diversified frequency center through multiple groups of transmitting & receiving antennas equipped in one system, it can acquisition up to 8 groups of frequencies at the same time. For example, a dual-frequency pipeline detection radar can be equipped with two antennas of 400M+200M, which can obtain high-resolution shallow information and low-resolution deep information in one acquisition.

 

2, The integrated all-in-one compact design, light weight 23kgs (50lbs) and durable, weatherproof materials offers a comfortable & easy-to-steer Radar which can be operated in almost any terrain, can be assembled on site in 2 minutes and fast dismantled for easy storage& transportation.

 

3, The modular design allows easy to service and to be repaired.

 

4, Outstanding location performance with good resolution up to 1mm, real-time data collection and display . The powerful DSP core allows sub-surface map real-time display on high-contrast LCD, integrated digital color and gain enhancements maximize the location quality.  Advanced digital filtering eliminates unwanted signals and provide greater accuracy.  

 

5, Unique Location Mode is activated simply by reversing the cart, which provides an accurate snapshot of underground conditions with a cursor indicates the depth and location of buried utility.

 

6, Operating is simple, LCD with keypad and menu easy for user to access the DSP core. One-touch image recording helps easy data storage, images can be saved to flash cards and copied to a PC through third-party card readers.

 

7, The flashcard interface allows the Radar firmware being upgraded once it available.

8, Built-in super-capacity battery grants long battery life.


Software Applications:

1, Display mode: Real-time color rendering, color/Gray-scale row scan,Variable Area/Waveform display, can be used in linear scanning mode 256A color source to indicate the amplitude and polarity of the signal.

 

2, The Radar packages enriches the application of system, in addition to equipped with a dedicated radar data processing software, user can choose software module to perform data processing on PC.

The Modules available as:

2.1 Highway surface layer automatic tracking software: specially used for highway detection, removal of interference automatically.

2.2 Highway structure can be stratified and automatically tracked to show the pile number, layer thickness and thickness deviation in spreadsheet.

 

3, Structure Scan Toolkit: 3-dimensional depth profile, reinforcement mesh perspective, pipeline positioning, building holes, cracks showing.

 

4, Structure analysis software: Steel bar distribution depth positioning display, municipal pipeline distribution positioning.

 

5, Bridge structure and rust analysis software: Bridge steel bar distribution and corrosion judgment analysis software.
