INTRODUCTION The Detector Duo is an innovative system capable of detecting tubes and both metallic and non metallic cables buried underground.  Following  standard  radar  principles,  the  Detector  Duo  uses  a  high performance  electromagnetic  sensor  equipped  with  e.m.  transmitters and receivers. The fundamental characteristic of this system is the simultaneous use of two frequencies, permitting the identification of both shallow and deep utilities at the same time. The groundbreaking control unit is extremely compact and lightweight at just 1Kg , and is compatible with 2 ATS antennas with frequencies of 700MHz and 250MHz located in a single container. The simplicity of  this  instrument  means  that  a  brief  training  course  is sufficient  to permit it to be used correctly.   I.D.S.

HOW TO USE THE DETECTOR The  main  targets  when  performing    utilities  investigations  with  the DetectorDuo consist of either extended structures (such as an interface between  layers,  pipes  parallel  to  the  investigation  direction  etc.)  or quite small structures (such as pipes perpendicular to the investigation direction, cavities and rocks etc.). Fig. 7.1 shows how a flat  interface gives rise to a flat trace while  a small  structure  such  as  a  pipe  produces  a  hyperbolic  trace.  This  is because the echoes form the flat plane at different values of x take the same time to reach the DetectorDuo. For the pipe, however, the echoes from  its sides  take  a  longer  time  to  reach  the  DetectorDuo  than the echoes from its top surface.

All rights reserved o As the propagation speed in the medium increases (vm), the ratio between  the  flight  time  of  the  outwards  and return  signal twt relative  to  echoes  originating  from  lateral  points  and  the twt relating to the top surface of the target decreases. Therefore the hyperbola widens with higher propagation speed, vm. o With  increasing depth of the target, the ration between the twt relating to the echoes from the side points and the twt relating to the  top  surface  of  the  target  decreases.  Again,  the  hyperbola widens with increasing target depth. o For  equal  propagation  speed,  depth  and  type  of  target,  the hyperbola  will  be  wider  for  geometrically  larger  targets  (for examples for wider diameter pipes). When interpreting the maps, it is therefore a good  idea to remember that the width of a hyperbola does not just depend on the geometrical size and shape of the target. Fig. 7.2 shows two maps featuring echoes of  an  irregular  interface  between  two  layers with  different  dielectric properties  (asphalt)  and  six  pipes  situated  perpendicularly  to  the direction of investigation.

All rights reserved As can be seen in Fig. 7.2, the echo of a target doesn’t simple consist of  a  single  dark  band,  it  consists  of  alternate  dark  and  light  bands. These derive from the signal minimums and maximums reflected back from the target (in fact, the black and white bands represented in the figure  correspond  to  maximum  and  minimum  signal  amplitude respectively). A hyperbolic echo can be used to convert the ordinate of the map from time (nanoseconds = ns) to depth (meters= m). To do this, the hyperbola traced in ns ordinates is compared with a family of hyperbolas  traced with  ordinates  in  meters,  obtained  from  that  in  ns ordinates with various values of vm. The best vm approximation to the real  value  is  that  with  the  most  similar  aperture  to  that  of  the  one traced in time ordinate. Once vm has been identified, the depth of the target corresponding to the hyperbolic section can be found. There are no definitive criteria for interpreting diagrams and often you have to depend  on  experience.  In  any  case,  it  is  best  to  collect  the  largest possible  amount  of  information  for  an  area  under  investigation,  and use it to help choose the most appropriate equipment and investigation parameters. To conclude, we have an example below of a real situation featuring two pipes side by side (Fig. 7.3). This example is significant in that  it shows the diagrams of the same structure (the pipe) placed perpendicularly then parallel to the direction of investigation.

All rights reserved APPENDIX A -  THE PRELIMINARY INVESTIGATION  The  first  fundamental  phase  for  any  field  survey  consists  in  the preliminary  investigation:  its  scope  is  to  acquire  all  the  necessary information for the logistics of the operation, taking  into account the objectives to be performed. In  the  specific  case  of  a  georadar  investigation  for  underground utilities searching, the first thing to consider is the accessibility of the site, in terms of taking into account the space available for the passage of the antenna trolley and considering any architectural obstacles that could cause an obstacle to the data  acquisition phase. Often, in fact, the  investigation  is  performed  in  streets,  squares  and  on  pavements with  a  relatively  high  level  of  urban  traffic,  and  above  all,  in  the presence of randomly parked cars. The  main  points  to  be  considered  during  this  phase  are  described below:  Specific  permissions  must  be  obtained  (access  to  pedestrian zones, permission to interrupt the traffic flow, etc.);  Any difficulties in accessing the site must be considered;  The space available;  The presence of parked cars;  The level of traffic;. It is the task of the user to take these points into consideration when programming the work. APPENDIX B -  THE TECHNICAL MAPS Technical  maps  of  the  existing  utilities  are  produced  by  the  various utilities companies. These give general indications in a schematic way about the type and position of the utilities that are managed and/or have been constructed by them. These maps can be requested by faxing or writing to the cartographic or planning office of the companies, specifying clearly the streets and areas of interest.

All rights reserved The  most  important  types  of  utilities  (which  may  be  managed  by different agencies) to be considered are:  Public Street Lighting  Low, Medium and High Voltage Electricity Cables  Water supply  Gas  Telephone Cables  Sewers Even  though  they  may  be  very  generic,  these  maps  represent  an important support during the extraction and data interpretation phases, since they give the user a first  idea,  if not an exhaustive one, of the utilities that are present. For this reason, it is  important that the user activates the procedures for obtaining these maps well  in advance to make sure that they will be available during the data extraction phase. APPENDIX C -  OPENING MANHOLES This phase is normally performed once the acquisition phase has been completed,  and  consists  in  opening  the  manholes  present  in  the investigated site.  The  data  regarding  the  depth,  diameter,  and  direction  of  the  utility should be saved on the work sheet: this will provide you with further reference  data  during  the  interpretation  phase,  and  will  allow propagation  velocity  estimates  to  be  performed  in  order  to  calculate the depth of the identified utility as precisely as possible.
