As the underground distribution network becomes increasing complex the potential for fatalities, cost to repair damaged utilities and possible fines to recover loss of service can be a potential hazards with drilling and excavating services. Vacuum excavation utilizes a high pressure air or water stream to penetrate, expand and break-up soil. Loose soil and rocks are simultaneously removed by a vacuum. This technique is typically used to create a hole one to two feet square and as deep as required to expose the buried utility. When utilized properly the method is a safe, non destructive means of excavation.
Advantages of Vacuum Excavation:
- Locate and expose underground utilities with no risk
- >High quality vacuum excavation
- Dig effectively in any type of soil
- More productive than open pit/backfill methods
- Clean and self-contained
- Compact applications
- Increased excavation speed
In general, vacuum excavations either expose a utility or remove earth in close proximity to a utility. An example of exposing the utility would be day lighting or potholing a gas main to determine its exact vertical and horizontal position, also known as Quality Level A in the field of Subsurface Utility Engineering. An example of the second general use would be an excavation in preparation for a boring or monitoring well that is within one meter of an existing utility.
Typical Applications:
- Vacuum Excavating/Utility Potholing
- Virtually any excavation job that involves existing utilities
- Quality Level A confirmation of sub-surface utility locations
- Advanced pre-job surveying and utility mapping
- Clearing for boring and monitoring well installation
When excavating in the proximity of buried utilities, vacuum excavation is a safe alternative to hydraulic methods and an efficient alternative to hand digging.
