Abstract: A saw blade for a sawing machine for cutting micro trenches for receiving at least one duct or cable. The saw blade includes coding elements such as holes, depressions or protrusions. The holes, depressions or protrusions form at least one code symbol representing a unique identity (ID) for the saw blade.

Abstract: A method for placing at least one duct/communication cable below a road surface in an area. The area comprises a first layer and a second layer, the first layer being a road layer, such as asphalt or concrete, and the second layer being a bearing layer for the first layer and being located below the first layer. The method comprising the steps of cutting a micro trench in the area through the first layer into the second layer, placing at least one duct/communication cable in the micro trench so that that duct/communication cable is placed below the first layer, and filling the micro trench so as to restore the road surface.

Abstract: The present invention relates to a machine arranged for sawing micro trenches and placing ducts/cables in micro trenches, said machine comprising a saw blade arranged for sawing a micro trench in an area; said machine further comprising: a stabilizing device arranged for stabilizing the walls of said micro trench when placing ducts/cables into said micro trench, said stabilizing device being positioned immediately behind said saw blade in said micro trench, and said stabilizing device comprising guiding means for guiding at least one duct/cable when placed into said micro trench; said saw blade and said stabilizing device are arranged to be lowered and elevated independently of each other.

Abstract: The present invention relates to a control method in a system comprising —a server unit having computer means, communication means and a first data base, said first data base including positioning data and a plurality of work orders, wherein said work orders are related to said positioning data; and —a sawing machine having computer means and communication means, and being arranged for sawing trenches in an area; said method comprising the steps of: —transmitting, by said server unit, a first data flow A comprising a first work order to said sawing machine; and —controlling said sawing machine by means of said first work order. Furthermore, the invention also relates to a system thereof.

Abstract: The present invention relates to a method for placing at least one duct/communication cable below a road surface in an area, said area comprising a first layer (L1 and a second layer (L2), said first layer (L1) being a road layer, such as asphalt or concrete, and said second layer (L2) being a bearing layer for said first layer (L1) and being located below said first layer (L1), said method comprising the steps of: cutting a micro trench in said area through said first layer (L1) into said second layer (L2); placing at least one duct/communication cable in said micro trench so that said at least one duct/communication cable is placed below said first layer (L1); and filling said micro trench so as to restore said road surface.

Abstract: A machine arranged for sawing micro trenches and placing ducts/communication cables in micro trenches. The machine comprises a saw blade arranged for sawing a micro trench in an area. The machine further comprises a stabilizing device arranged for stabilizing the walls of the micro trench when placing ducts/communication cables into the micro trench. The stabilizing device is positioned immediately behind said saw blade in the micro trench. The stabilizing device is configured to guide at least one duct/communication cable when placed into said micro trench.
