BS EN 10223-8:2013EN 10223-8:2013 (E) 4 1 Scope 1.1 Subject This European Standard specifies requirements for the mechanical properties, dimensio
20、ns, coatings, test methodology and delivery conditions of welded mesh gabions products. The general meaning of welded mesh gabion is a metallic box made of welded wire mesh to be filled with stone or other suitable material. Only the characteristics of the metallic cage are subject of this document.
21、 Filling materials, e.g. coarse armourstone, are covered in other standards. This document covers gabions produced from welded wire fabric and accessories coated with a zinc coating, a hot-dip galvanization or a zinc-aluminium alloy, polyvinyl chloride (PVC) or stainless steel. Accessories include c
22、omplementary materials such as spiral binders, rings, lacing wires, tie-rods or spacers. 1.2 Intended use The intended use for the considered construction product is: earth retention, soil reinforcement systems, river training, erosion control purposes, slope retention, sound barriers, fencing, land
23、scaping, covering or cladding as well as architectural purposes. Figure 1 below shows some relevant examples of applications of gabions. Key 1 stepped face retaining structure 2 flush face retaining structure 3 slope protection 4 free standing walls, e.g. sound barrier 5 claddings, e.g. for architec
