16 Utility AirSpade Technical Applications Bulletin
Across the modern landscape, the proliferation of underground utilities
has grown significantly as we have come to appreciate the improved
visual aesthetics. While undergrounding is initially expensive, utility
providers benefit from increased reliability and protection from the
elements. However, the potential for service interruptions due to
accidental strikes when uncovering underground lines for maintenance
or during construction, is a growing concern. Per this illustration, as
underground utilities continue to proliferate, the potential for accidental
strikes on adjacent utilities increases.
Dry excavation in conjunction with the Utility AirSpade facilitates the
safe excavation of underground utilities and minimizes the chance of a
service interruption. Unlike mechanical excavation techniques, airspading
efficiently removes or loosens soil without damage to underground
facilities. Underground utilities where accidental strikes commonly
occur include:
Irrigation Lines: Water for lawns, shrubs and trees
Street Lighting Lines: A/C power for street lights
Traffic Signal Lines: Low voltage lines providing traffic signal synchronicity
Storm Drainage: Runoff from curbside storm drains
