What Does Vibratory Plow Mean?
A vibratory plow is an attachment to a tractor or other prime mover that cuts a slit in the ground as it lays a small-diameter utility cable or pipe.
The oscillation of the blade makes the excavation faster and more efficient than a static blade. It is considered a trenchless method because the slit is so narrow and does not require a wide excavation as in traditional trenching.
Trenchlesspedia Explains Vibratory Plow
The use of a vibratory plow is a good choice for workers laying small cables or pipes for utility companies. It is also an effective method for landscaping contractors. Vibratory plowing is a quick process. It is efficient and minimizes restoration because no trench is dug.
The blade of the plow is attached to a shaker box, and the resulting vibration remains separate from the operation of the vehicle. HDPE pipe less than 8 inches in diameter may be used, and the vibratory plowing can lay pipe at the rate of 35-feet per minute under good conditions.
The resulting groove does not require backfilling and does little damage to the ground surface. The excavation can easily be restored by running a tractor tire over the slit.
