Micro trench sawing device and method for sawing a micro trench

摘要

Micro trench sawing device (100) comprisinga supporting frame (110);a saw blade holding means (120), holding a saw blade so that it is horizontally adjustable within a vertical adjustment plane (AP), between a forward (125) and a backward (126) position;a saw blade driving means (130), driving the said saw blade for sawing a micro trench (21,22) in the ground (10);a main motor (140), fixedly mounted in said frame and driving the saw blade driving means; andwheels (151,152,153,154), defining the corners of a polygon (155) on said ground.The invention is characterised in that the vertical adjustment plane intersects the said polygon but does not intersect the main motor.
