ground penetrating radar scanning method
Analysis of the passage of electromagnetic waves emitted by the ground penetrating radar through the thickness of the ground and underground utilities can scan through the ground penetrating radar to see what is hidden under a layer of rocks to a depth of 100 m By changing the frequency of the wave penetrating radar can capture small objects at depths up to 10 m and extended by GPR survey over large pits depths.
The possibilities of the ground penetrating radar survey.
Ground penetrating radar can detect metallic and non-metallic objects , voids and irregularities sizes :
At a depth of 5 cm to 2 m, used ground penetrating radar with a frequency of 250-600 MHz.
10-20 cm depths of 3-5 m, the antenna unit is used GPR 150-250 MHz.
2.1 m at a depth of 20-60 m , suitable ground penetrating radar VINE series with a frequency of 50-150 MHz.
2.4 m at depths of 60-100 m, ground penetrating radar is indispensable VINE -H1 at a frequency less than 25 MHz and the antenna length 6.12 m
Finding GPR scanning of gas pipelines, oil pipelines , water pipelines , unauthorized tie-in pipelines is easy.
Ground penetrating radar can detect sources of soil moisture , leaking water pipes , sewers , hidden places of the overflow water .
GPR detection of plastic and metal pipes, cables , mapping hidden communication is done by computer processing of the results of ground penetrating radar surveys .
Determining the status of concrete structures. Ground penetrating radar to determine the presence of voids and cracks , the location of reinforcement, the bearing capacity of soils.
Being old and new foundations assessment , mapping of buried foundations.
Mapping of soil contamination .
A survey of roads, runways (determination of pavement layer thickness determination of the nature of reinforcement , detection of defects , areas of flooding ).
Determining the status of dams , bridges and dams. GPR scans soil around the perimeter of the structure and foundation.
Survey landslides and karst structures , tectonic disturbances .
The study of the geological structure of the territories.
Identification and mapping of mineral resources , exploration areas and quarries.
How to commission a ground penetrating radar survey.
Fill out an application on georadar survey .
Then together we define goals GPR scanning , choose a suitable ground penetrating radar antenna unit with the optimal solution out of GPR survey.
Draw up the terms of reference . Sometimes require the use of the TK several models of GPR .
Agree on the timing and cost of GPR scans.
Signing a contract for a GPR survey.
After conducting an advance payment Georadar scan indicated in the TOR GPR .
Preparing a report on the results of GPR scans. To report the verification certificate ground penetrating radar .
The results are presented in print and electronic form, in the form of a report ground penetrating radar survey.
