ABSTRACT:
A device for boring tunnels to accommodate electrical cables or conduits in the thickness of an insulative material of a composite wall panel exhibiting a layer of this material covered on one or both sides with a rigid facing sheet made up of a mobile system and a positioning and guiding device for the mobile system. The mobile system incorporates a boring member mounted at the end of a flexible member, and the positioning and guiding device incorporates a removable support featuring means for attaching it to the or one facing sheet, in line with an opening formed in the latter, and a bent guide conduit adapted to be inserted into this opening. This conduit enables the boring and flexible members to penetrate into the insulative material parallel to the facing sheet, in the required direction and to the required distance.
