Trenching System

摘要

A system for uncovering and sealing a narrow trench. The system comprises several subsystems, including a work machine, a frame for providing a seal with the surface to be trenched, a saw blade, a vacuum system, a system for placing product, and a resealer. The blade includes rotatable tooth bits, which may be rotated and secured to create a blade for narrower or a wider trench. A removable cover and the blade are easily changeable. A surface engaging member on the frame is manipulated to maintain a seal with changing ground surfaces. Additionally, the vertical location of the blade within the frame is adjustable to create a deeper or shallower trench.

1. A method for cutting a narrow trench in a surface using a rotatable blade moveably attached to a frame and disposed within a cavity defined by a hood assembly, the hood assembly comprising a surface engaging member, the method comprising:
adjusting the blade relative to the surface engaging member to achieve a desired trench depth; rotating the blade to cut a trench; positioning the surface engaging member on the surface adjacent the blade; and applying a downpressure greater than the weight of the hood assembly to the surface at the surface engaging member to stabilize a portion of the surface adjacent the trench.
