METHOD FOR PLACING AT LEAST ONE DUCT/COMMUNICATION CABLE BELOW A ROAD SURFACE IN AN AREA |
摘要 |
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. |

1. A machine for placing at least one duct/communication cable below a road surface in an area, said 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 machine comprising:
a saw blade arranged to saw a micro trench in said area through said first layer into said second layer, wherein said micro trench has a depth d; and a stabilizing device positioned immediately behind said saw blade and being arranged to place a plurality of ducts/communication cables in said micro trench by means of guiding means comprised in said stabilizing device so that said plurality of ducts/communication cables are placed below said first layer; wherein said machine is arranged to continuously adjust the depth d while in operation. |
