Abstract
A method of exposing a buried utility under a roadway by cutting an access hole in the roadway, vacuuming away dirt surrounding the buried utility, and spraying at least one of pressurized water or compressed air into the dirt to loosen the dirt. A vacuum device having a vacuum nozzle, a compressed air nozzle, and a pressurized water nozzle.
Claims10
A vacuum device for removing dirt surrounding a utility buried under a roadway comprising:
- a vacuum nozzle having a diameter of about 2 to about 24 inches;
- a spray device connected to the vacuum nozzle, the spray device having at least one pressurized water nozzle or compressed air nozzle, and the spray device being configured for spraying at least one of pressurized water from the pressurized water nozzle or compressed air from the compressed air nozzle into the hole to loosen the dirt surrounding the buried utility;
- a compressed air manifold at least partially surrounding the vacuum nozzle, and at least one air nozzle connected to the compressed air manifold wherein the compressed air manifold is movable in relation to the vacuum nozzle so that the compressed air manifold can be positioned along a length of the vacuum nozzle;
- and
- a pressurized water manifold at least partially surrounding the vacuum nozzle, and at least one pressurized water nozzle connected to the pressurized water manifold, wherein the pressurized water manifold is movable in relation to the vacuum nozzle so that the pressurized water manifold can be positioned along a length of the vacuum nozzle.
