Abstract
A device for slicing through soil and simultaneously inserting silt fence into the soil. Silt fence is a synthetic material installed in and above the ground to impede silt erosion from areas disturbed by construction. The device comprises a soil disrupter for slicing thinly through the soil 8 inches to 12 inches deep, and an apparatus, operating at the same depth, for converting silt fence, manufactured on a roll, into a vertical position in and above the ground. The apparatus includes a vertical wheel operating between two parallel panels, acting as a moving pivot point where the horizontal silt fence is converted to a vertical position between the panels. The panels hold the soil open while the vertical wheel simultaneously inserts silt fence into the opening. As the machine progresses, soil collapses against the silt fence, thus securing the silt fence in the desired position.
