Definitions
- the present invention relates to a shielded draining pipe mesh according to the introductory portion of the independent claim.
- EP2160505 discloses a trellis like arrangement of drainage conduits that is intended to be mounted on a wall.
- the drainage system is then typically covered by shotcrete that is left to set.
- shotcrete there is a risk that the conduits, that in cross section are U-shaped with the open side facing the wall, receive shotcrete that fully or partially fills the conduits.
- An object of the invention is therefore to provide a shielded draining pipe mesh with an improved resistance to influx of shotcrete.
- the invention relates to a shielded draining pipe mesh 1 adapted for mounting on a surface and for being covered by a substance 7.
- At least one pipe 2 is in cross section essentially U-shaped with an open side intended to face the surface.
- the pipe 2 is provided with a shield 6 that covers the open side, and preventing shotcrete to flow across it. This has the advantage that the pipe interior does not fill up with shotcrete, but lets water enter into the pipe interior.
- the pipe 2 is provided with side bands 3a-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.
- the shield 6 may be constituted by a metal net.
- Fig. 1 shows an overview of the shielded draining pipe mesh
- Fig. 2 shows a cross section of a draining pipe along A-A mounted on a surface
- Fig. 3 shows the cross section of a draining pipe during shotcrete application
- Fig. 4 shows the cross section of a draining pipe when shotcrete application has been completed
- Fig. 1 shows an overview of the shielded draining pipe mesh 1.
- the mesh is constituted by a trellis like structure of draining pipes 2a-b, one set of which extends downwards at an angle to the left 2a and another set which extends downwards at an angle to the right 2b.
- the pipes allow water that leaks through the wall surface to efficiently be drained.
- 3a-b which are aligned against the surface that the shielded draining pipe mesh 1 is fixed to.
- the pipes cross each other at regular intervals and at these intersections attachment elements are provided.
- One of these intersections is provided with an intersections box 5 giving access to the interior of the pipes if necessary.
- a line A-A indicate where the cross section shown in the proceeding figures are made.
- Fig. 2 shows a cross section of a draining pipe 2 along A-A mounted on a surface 8, typically a rough stone wall.
- the side bands 3a-b extending along each side of the pipe are also shown.
- a like shielding net 6 extends from one band to the other and covers the open lower side of the U- shaped pipe 2.
- the shielding net extends along a flat surface slightly above the stone wall below the pipe and prevents any debris from entering into the pipe.
- the net may for example be made from metal or plastic and is mesh like with a sufficiently fine structure to prevent shotcrete from passing through it.
- Fig. 3 shows the cross section of a draining pipe during shotcrete 7 application, and in the figure shotcrete has built up to a layer extending about halfway to the top of the pipe. A minor amount of shotcrete has seeped in under the net 6 near the edges of the side bands 3a-b, but the net has otherwise prevented the shotcrete to enter the pipe.
- Fig. 4 shows the cross section of a draining pipe when shotcrete application has been completed and the pipe is fully covered by hardened shotcrete. The net 6 has prevented the shotcrete from entering the mesh, leaving the interior of the pipe almost fully free of concrete so that there is no risk of clogging.
