МULTICHANNEL GPR SYSTEM
Determination of thicknesses and composition of structural layers of railways embankment Delimitation of subsidences in layers of ballast section and soil foundation Determination of roof geometry for soil foundation Mapping of underground utility lines crossing railway еmbankment Check of railway embankment structure for compliance with project documentation
Features and Advantages
Several aerial units allow inspecting all width of railway bed: endwise, along the left and right roadsides; thus, the speed of the railway monitoring raises essentially Replaceable aerial units with various frequencies from 400 MHZ (in standard version) to 1,700 MHZ can be used for detailed study of the top of the ballast section The system allows working with all types of sleeper grid
Specifications
The system provides for connection of up to 4 aerial units (if necessary up to 8)
Recording speed on each of 4 channels - 200 lines per second that provides no less than 6 lines per 1 m at a speed of 120 km/h
