Similar to hydro-excavation (without the water), air knifing utilizes high velocity air to penetrate, expand, and break up soil. The soil is then removed from the area using a powerful vacuum. Air knifing (aka potholing or daylighting) includes all of the advantages of hydro-excavation.

2021年4月19日 · Soil excavation by way of air knife enables workers to remain at a safe distance from trench hazards and help prevent cave-ins. Given its softer approach to digging, it also mitigates accidental damage to dangerous underground lines and buried infrastructure. Using an air knife, crews can accurately locate the depth of existing utilities.

An industrial air knife is a pressurized air plenum containing a series of holes or continuous slots through which pressurized air exits in a laminar flow pattern. The exit air velocity then creates an impact air velocity onto the surface of whatever object the air is directed.

PES has added a new service to provide utility clearance using air knifing. The system includes an AirVac compressed air and vacuum unit attached to an AirSpade 4000 air excavation tool for utility potholing. This system can efficiently clear pre-probing locations to a depth of 5 ft. to eliminate damaging utility lines.

Air Knifing is a non-mechanical and non-destructive process that uses high pressure air coupled with our vacuum truck to excavate and evacuate soils. Both processes allow for quick, clean, and precise excavations which require less backfill, less labor force, less restoration, and less environmental impact than conventional methods.

Air knifing utilizes high-velocity air to penetrate, expand, and break up the soil to remove it with a powerful vacuum. The advantage that air knifing has on hydro excavation would result in dry soil waste, reducing the disposal cost for the customer.

Air Knife Excavation is a tool for breaking up soil that uses high-pressure air to penetrate and expand the soil. This method of excavation is non-destructive and quite safe. Once the air knife looses up all the necessary soil, it is vacuumed up.

Air Vacuum excavation is process using high-pressure air to loosen soils. An air vacuum is used to move the loose soil and rocks into a debris tank for later disposal, or back-filling the hole that's been excavated.

2018年10月9日 · MPW’s air knifing excavation offers an environmentally safe digging technique without harming critical underground utilities or structures. Unlike hydro excavation, air knifing utilizes pressurized air to penetrate and fracture soil and sediment without the need for water.

Vacuum excavation/air knifing utilizes a high pressure air to penetrate, expand and break-up soil. Loose soil and rocks are then vacuumed directly into a drum. Upon completion of the borehole, the contents which were removed are then deposited back in the boring.
