Sealing cover for landfill sites

摘要

Sealing cover for landfill sites, for example refuse landfill sites, consisting of two sealing layers (1) and (2), an intermediate control filter layer (3), an injection line system (4) and a second line system (5), both of which are arranged within the control filter layer (3), a grid-shaped area division the individual areas of which are partitioned off with respect to one another by sealing connection (11) between (1) and (2), a collection shaft or a tunnel in which the lines (4) and (5) terminate, a drainage layer (9) with a drainage line system, which drainage layer is arranged above (1) and a sealing layer (10) above (9). In the event of failure of the sealing (1) the control filter layer (3) is filled with a curing and sealing material via the injection line system (4) and the impermeability thus restored. <IMAGE>
