Method of and apparatus for trenching

摘要

An excavation apparatus adapted for connection to a tool of a construction vehicle comprises a framework having a proximal end and a distal end, the framework including a trenching device positioned intermediate the proximal end and the distal end for digging a furrow in which a silt fence is positioned. The proximal end has a mounting arrangement for clamping the framework to the tool of the construction vehicle and the distal end has a depth limiting arrangement for limiting the digging depth of the trenching device.
