UNDERGROUND UTILITIES

Research and mapping of underground utilities

Adastra Engineering is specialized in the identification and mapping of underground utilities buried in the first subsoil. Our systems, which rely on the most advanced technologies, allow to obtain, at reduced costs and with the maximum rapidity, the network graph of utilities to plan interventions or to avoid interference with buried artifacts in the case of excavations (laying of cable ducts, sewers, pipes, etc.).

  • Research on very large areas at reduced costs
  • High resolutive capacity
  • No functional interruptions and costly damages during excavation
  • Integrated reconstruction on digital support of underground utilities

More system for a great result

The georadar methodology allows the identification, with centimeter precision, of pipes, ducts and electric cables up to a few meters of depth. It also allows to discriminate the different types of buried artifacts and to obtain a complete reconstruction of the networks of underground utilities.
The Ground Probing Radar systems can operate in city traffic even in critical conditions without interfering with the circulation of other vehicles.

Operating principle

The operating principle is based on the generation of electromagnetic waves that propagate underground and that are reflected with a different intensity when they encounter buried objects (power lines, pipes, chambers, wells, cavities, etc.).
The reflected echoes are transformed into images through the application of particular calculation algorithms; the images are subsequently interpreted by specialized personnel and the map of underground utilities is draw on a digital GIS / CAD support.
Adastra Engineering uses integrated methodologies that include in sequence:

  • multi-channel wheeled georadar survey;
  • electromagnetic survey;
  • high precision topographic survey with GPS systems or robotic TS;
  • video inspection;
  • monographs of wells;
  • implementation of a GIS / CAD that integrates the set of data collected and known data.

Main instrumentation

  • IDS X-Stream multiarray system (up to 40 antennas);
  • GPR GSSI type SIR with antennas from 75 Mhz to 900 Mhz;
  • C.Scope MXL2 cable avoidance tool with MXT energizer for electromagnetic investigation in the frequency domain;
  • Trimble R7 dual receiver GPS (RTK and VRS mode);
  • Robotic TS Trimble 5600 DR200 +;
  • Inspection cameras;
  • Workstations with dedicated geophysical programs and GIS / CAD.
