The ground penetrating radar, otherwise known as GPR, is a handy form of technology that many construction companies use. Mostly used in concrete and core drilling applications, ground penetrating radar is excellent at allowing professionals to work safely without damaging things like conduits or rebar that run deep inside of concrete. It can collect data underground and through concrete while also being able to analyze the data. Read on for an essential guide for ground penetrating radar!
The Main Idea of Operation
Essentially, the main idea of ground penetrating radar is that it does precisely what the name implies. But how does it do this? A high-frequency radio signal is shot into the ground and bounced back up to its receiver. Stored through digital means, the data is then recorded by a computer. This computer will then measure how long the signal is pulsed to travel back to the receiver from its main target. The pulse’s travel time will reveal how deep it went and where it went to its target. This system will capture and interpret the data from the signals and present it on an LCD screen for the users, which will usually be concrete cutters, drillers, and other construction-based contractors.
Underground Data Collection through Ground Penetrating Radar
To find targets underground, multiple types of GPR are required. The type will depend on how deep and how big the target is. Once the target has been located, the signals from the GPR unit can then be sent down to it. Signals can bounce back and forth around a thousand times a second. Once the signals have returned the data, the user can attempt to analyze it in the field or save it for later use. Saving it for later will allow for more time and more analysis if required.
Concrete Data Collection
Specific targets require a different kind of GPR. Conduits, rebar, and post-tension cables are usually buried under concrete. GPR could then be used to not only find these targets but also to scan them. Scanning these targets can help determine the thickness of the concrete and where the targets are. A map is then created, and virtual slices of the image can then be used to create a second, more detailed 3D map of the same image.
Data Analysis with Ground Penetrating Radar
Data analysis is affected by a few factors, like soil and material the signals are moving through. A more experienced user from G&M Services can help in interpreting this type of data.
