Simple, cheaper, more damage=proof tunnel sealing web

摘要

A method for fixing web or plates (1) for sealing purposes in underground workings (2) of civil and hydraulic engineering and tunnel construction uses strips of hook-shaped fasteners (5) fixed to the web etc. and a fleecy layer (3) with a surface (3a) formed for pull-proof attachment to the fasteners. The sealing web (1) is pressed onto the fleecy layer and because of the penetration of the hooks (5) a mechanical fastening is achieved which can be opened and closed again.
