A Draining Mesh Module and a Method of Operating a Draining Mesh in a Construction

A draining mesh module for building into a construction, such as a tunnel wall, to provide draining channels in said construction, comprising at least one semi pipe of a flexible material, wherein said draining mesh module has a longitudinal direction and a cross direction extending crosswise to the longitudinal direction, said at least one semi pipe constituting at least a part of a channel extending from one longitudinal end to an opposite longitudinal end of the draining mesh module, and the longitudinal ends of the draining mesh module is provided for interconnecting longitudinal ends of two adjacent draining mesh modules, whereby a channel in one of those two draining mesh modules is connected to a channel in the other of those two draining mesh modules.

• wherein at least two adjacent channels are extending from one longitudinal end to an opposite longitudinal end of the draining mesh module said two adjacent channels extending in a wave like manner and in a mutual 180° phase displacement whereby the two adjacent channels are interconnected at junctions where troughs and crests of the respective waves meet, and
• wherein at least two channels, different from said adjacent channels, are mutually disconnected throughout between said longitudinal ends of the draining mesh module.
