Today, thanks to the use of military research for peaceful purposes, we have the opportunity to enjoy one of the most unique and modern geophysical instruments ground penetrating radar ( GPR) , which provides a unique opportunity for all who are willing to apply their knowledge and skills in a challenging and previously inaccessible areas. The possibility of ground penetrating radar ( GPR) to buy and effectively apply it in practice little is available due to its relatively high cost and the high level requirements of specialist training .
It’s no secret that the lion’s share of success in solving any , from the simplest to the most complex tasks , it is necessary for the owner of a certain knowledge , equipment and resources . But the possession of any means for improperly using all the opportunities provided by modern science and the latest developments of science and technology and industry can make a spent force and wasted investment.
ground penetrating radar ( GPR) can fully justify its uniqueness , because with this device trained operator can do quality research , and as a magician. “See” through the earth , stone and water. It is difficult to find an environment that is able to hide from the all-seeing ground penetrating radar ( GPR) their innermost secrets, such as voids and foreign bodies , internal structure , changes in the density and structure. All that is carefully hidden from our eyes , almost any anomalies under the ground – all ground penetrating radar ( GPR) reads like an open book .
The range of the successful use of the device affects the scale . In geology and mining , inspection and repair of roads , inspection of reinforced concrete structures and pipelines , with historical and archaeological research , search, mapping and exploration of underground communications , research and restoration of bridges , the environmental assessment of soil and water space , finding groundwater and underground tanks , ponds bottom study , studying the characteristics of snow and ice , finding treasures , inspections of railways , construction, agriculture and forestry, trenchless technology , particularly in horizontal directional drilling , indispensable practical application of GPR .
Research ground penetrating radar ( GPR) actively and successfully conducted in the field of security, where the device can successfully search and discovery , not only of unexploded ordnance , but other explosive devices . In the midst of fighting with ground penetrating radar can detect hidden and camouflaged buildings. Indispensable use of ground penetrating radar in the fight against terrorism and smuggling activities . Ground penetrating radar was in demand , and in the work of the ministry of emergency situations when the agency experts are using it to carry out the research, such as checking the technical condition of hydraulic structures , bridges, embankments, railways and roads . He became indispensable in the search for and rescue people trapped under the rubble . Opportunities ground penetrating radar studies are widely used in forensic science . Investigative agencies actively used ground penetrating radar to find hidden clues in large areas
Of course, you can do without ground penetrating radar in all the above areas , and to the old, traditional methods but is useless to deny or ignore the opportunities provided to us by scientific and technological progress. It is unlikely that anyone would want for room illumination light kindling or kerosene lamp , when you can use electricity. So is the case with the ground penetrating radar is safe to say that all who value time and money , who needs accuracy and reliability of the information , this device would be a good helper.
So, why is this device has become so popular in the world and won the undoubted respect of all who use it in your work?
The main advantages of using ground penetrating radar for engineering research – a little time spent on field work , efficiency issuing the final result and economy. Furthermore, georadar sensing requires a minimum of space required for the deployment apparatus, which often is a significant advantage when used in dense urban and industrial buildings.
Unlike other detectors (eg Locators ) ground penetrating radar shows not only the desired object , but also the environment around the target object and the characteristics of the containing object environment.
Georadar sensing provided a detailed investigation of the subsurface structure of the soil or of man-made structures, significantly reducing the costs of drilling instrumentation wells. In this case, the resolution of the spatial coordinates obtained in this method is much greater than the existing geophysical survey methods (eg , engineering seismology ), which reveals the fine structure of the structure of the cut.
The essence of the method consists in ground penetrating radar sensing radiation pulses of electromagnetic waves and recording the signals reflected from interfaces between layers probed medium having different electrical properties .
Using the ground penetrating radar can be productively explore any non-metallic environment – soil , water, air cavities , building construction – reinforced and not reinforced , structural layers of the pavement , and more. The result is a highly reliable , continuous incision probed medium , called GPR profile, or radiogram .
As required objects in ground penetrating radar ( GPR) advocate and non-metallic objects of different geometric shapes , the boundaries of layers in the ground or in another test medium , a place with high or low humidity, decompressed , fractured or contaminated zone – that is, any areas that differ in their electro-physical characteristics of the host medium .
Let’s start with the fact that conducting qualitative research , using ground penetrating radar in their work non-destructive method , called GPR . Through the use of this device manufacturing costs and research costs may be reduced to dozens, sometimes hundreds of times , which significantly affects the economic viability of the project and does not call into question the rationality of its use ! When dealing with historically significant objects using ground penetrating radar eliminates useless and detrimental to the destruction of the building or limits the production of excavation to the minimum necessary . Find treasures and historical values using GPR is truly indispensable !
The use of ground penetrating radar scan is presently the most promising for the successful and precise definition of the different characteristics of the object , which was made possible thanks to the unique high resolution and noise device . In comparison with other previously used methods of research work is characterized by the performance of ground penetrating radar in combination with both low- energy and resource-intensive , so the device has gained popularity in public services, when you want to search and examination of communications or finding groundwater.
Using ground penetrating radar requires no additional equipment to accommodate larger areas and powerful sources of energy does not depend on the quality of facilities and access roads . For this device are not important location and size of the object . He is able to study highly of both horizontal and vertical or sloping surfaces. Conduct research ground penetrating radar can be whatever the structure of the soil – sand, soil , clay , stone , ice , snow. Ground penetrating radar can run on different artificial surfaces such as brick, concrete, concrete, and so on.
And compact and quiet device creates minimal inconvenience to others when carrying out work in densely populated areas and densely built-up areas where communications are searched or damage to utilities . When ground penetrating radar survey excludes the earth moving , is not harmful to the environment and ecological balance is not disturbed .
In addition, using the construction of three-dimensional models , ground penetrating radar provides the opportunity to obtain a complete , detailed information on the object of interest .
Another important factor is that the ground penetrating radar is served by one or two operators , device Increase the capacity and reliable.
So, we become acquainted with the benefits of ground penetrating radar intended for research facilities located in shallow water to get detailed information about the object. The basis of the ground penetrating radar is the principle of the emission and reception of high-frequency electromagnetic pulse reflection from the boundaries of the objects in the environment different from their electrical characteristics .
