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.
Claims10
A machine for installing at least one duct/communication cable in an area comprising a first layer and a second layer, said first layer being a road layer, such as asphalt or concrete, and said second layer being a bearing layer for said first layer and being located below said first layer, said second layer comprising at least one of sand, gravel, stones and dirt;
- said machine comprising:
- a diamond saw blade arranged for sawing a micro trench to a depth of d in said area through said first layer and into said second layer;
- and
- a combined stabilizing and placing device positioned immediately behind said diamond saw blade for stabilizing said second layer in said micro trench while placing ducts/communication cables inside said micro trench by means of at least one guiding means comprised in said stabilizing device so that all said ducts/communication cables are placed below said first layer;
- wherein said machine is able to adjust said depth d;
- and wherein an operating depth of said stabilizing device in said micro trench is less than an operating depth of said diamond saw blade.
