Micro Trenching is one of the installation methods being utilized by contractors to bring fiber networks to consumers. Micro Trenching is an installation method in which a narrow and relatively shallow trench is cut, usually on an asphalt roadway. Trench dimensions can range from .75 to 2.24 inches wide and 8 to 16 inches deep. While cutting, a vacuum system connected to the cutter wheel cleanly diverts and transports debris away from the worksite. Once the conduit is laid, the trench is backfilled with a grout compound.
Advantages of Micro Trenching include minimal cutting width that boosts installation production and reduces costs of backfill, shallow depth placement which helps avoid encounters with existing utilities and jobsite cleanliness thanks to the vacuum spoil that removes debris.
David Donohue of Vermeer Mid Atlantic says “The Vac-Tron LP 533 SGT is the ideal vacuum for micro trenching, the high cfm’s and low noise output made communication and productivity simple.” David and Pfeiffer Enterprise Inc were demonstrating Vermeer’s micro trenching equipment and Vac-Tron’s LP SGT high cfm unit in Glen Bernie, MD in this photo.
