Containment sheet and relative containment structure comprising said containment sheet

Abstract

Containment sheet (1) comprising a flexible weave (2) defined by a plurality of reinforcement strips (3) interwoven with each other in a warp and weft pattern. Each reinforcement strip (3) comprises:—a polymeric coating capsule (4) surrounding a plurality of longitudinal channels (5) extending parallel to a longitudinal extension direction of the reinforcement strip (3) and arranged as aligned in a direction perpendicular to the longitudinal extension direction, and—a plurality of longitudinal reinforcement fibres (6) arranged within the longitudinal channels (5). The containment sheet (1) further comprises at least a connecting portion (7) connected to the flexible weave (2) and suitable for connecting the containment sheet (1) to a further containment sheet (1) and/or to an external structure (E).

         34 . The containment sheet according to  claim 29 , wherein said plurality of longitudinal reinforcement fibers are high tenacity city synthetic yarns. 
     
     
         35 . The containment sheet according to  claim 29 , wherein said polymeric coating capsule is made of polyethylene. 
     
     
         36 . The containment sheet according to  claim 29 , further comprising a layer coupled at least partially to the flexible weave. 
     
     
         37 . The containment sheet according to  claim 36 , further comprising a waterproof membrane interposed between the layer and the flexible weave. 
     
     
         38 . The containment sheet according to  claim 29 , wherein said reinforcement strips have a tensile strength between 1 kN/m and 1000 kN/m. 
     
     
         39 . The containment sheet according to  claim 29 , wherein said reinforcement strips have a width, measured between opposite side edges with respect to the longitudinal extension direction of between 10 mm and 200 mm, and wherein said reinforcement strips have a thickness, measured perpendicularly to the width, of between 0.1 mm and 50 mm. 
     
     
         40 . The containment sheet according to  claim 29 , wherein said reinforcement strips extending in a warp direction of said flexible weave are slidable relative to said reinforcement strips extending in a weft direction of said flexible weave. 
     
     
         41 . A containment structure comprising:
 at least two containment sheets according to  claim 29  and placed side by side, and   connectors configured to connect said at least two containment sheets at least at said connecting portions.   
     
     
         42 . The containment structure according to  claim 41 , wherein the connecting portions are defined by peripheral joint strips obtained by welding free terminal ends of said reinforcement strips, and wherein said connecting portions are at least partially overlapping with each other at overlapping areas, said connectors comprising fasteners engageable to said at least two containment sheets at such overlapping areas to connect them. 
     
     
         43 . The containment structure according to  claim 41 , wherein the connecting portions are defined by free terminal ends of the reinforcement strips folded and fixed to the reinforcement strips themselves to form connecting through cavities, and wherein said connectors comprise connecting elements insertable at least partially within the respective connecting through cavities to connect said at least two containment sheets. 
     
     
         44 . The containment structure according to  claim 41 , wherein said connectors further comprise connecting elements at least partially insertable within respective flexible weaves straddling adjacent reinforcement strips.
