Shielded draining pipe mesh

Abstract

The invention relates to a shielded draining pipe mesh ( 1 ) for mounting on a surface and for being covered by shotcrete ( 7 ). The pipes ( 2 ) are U-shaped in cross section with an open side facing the surface. The pipe ( 2 ) is provided with a shield ( 6 ) that covers the open side. The pipe remains enclosed while applying shotcrete, but the shield ( 6 ) allow water to flow through it into the interior. In one embodiment the pipe ( 2 ) is provided with side bands ( 3 a - b ) extending along either side of the edges of the pipe at its open side, where the shield is attached to the side bands giving additional mechanical strength.

1 . A shielded draining pipe mesh adapted for mounting on a surface and for being covered by a substance, where at least one pipe in cross section is essentially U-shaped with an open side intended to face the surface, characterised in that said pipe is provided with a shield that covers the open side, and where the shield is constituted by a net like structure. 
     
     
         2 . A shielded draining pipe mesh according to  claim 1 , characterised in that said pipe is provided with side bands extending along either side of the edges of the pipe at its open side, and where the shield is attached to the side bands.
