Element in sheet form, as a network, particularly for geotechnical applications

摘要

An element in sheet form (1), such as a net, particularly for geotechnical applications, comprising a body of extruded polymer in sheet form (2) formed by overlapping at least two sets of filaments (2a, 2b) in order to provide a structure shaped grid, characterized in that said shaped body sheet (2) is provided with a first polymer, defining said shaped structure reticle, and a second polymer, which is coextruded mutually with said first polymer to form said body of extruded polymer in sheet form as a single element, and the second polymer being such arranged in regions (10) of at least one face of said body in sheet form (2), these regions being (10 ) of said second polymer formed by a plurality of mutually parallel linear strands that are arranged on and extend only along a set (2a) of said two sets of f ilamentos, said first polymer physical and mechanical characteristics of compressive strength and tensile strength so that said network has functional strength and durability required by the network, said second polymer having a high coefficient of friction.
