The typical use for the considered products is retaining of unstable slopes, controlling and preventing rockfalls and loose debris flow along roads, highways and railway, urban areas, mines and quarries,and for snow avalanche protection.
Wire ring net panels are ring panels where each ring is made by several loop bindings, each one obtained by looping a single steel wire. Each ring is connected with four or six contiguous rings in order to create a net as shown in Figure 2.
For the connection of the panels, shackles or wire rope shall be used. The strength of the connection formed shall be equal to or greater than the tensile strength of the ring net panel.
The wire of the ring net panel is protected with a metallic coating. Depending on the corrosivity of the environment for which the wire ring mesh is installed (see ISO 9223), possible options for metallic coating are presented in Table A.1.
NOTE Working life (product) 一the period of time during which the performance of a product will be maintained at a level that enables a properly designed and executed works to fulfil the essential requirements (i.e. the essential characteristics of a product meet or exceed minimum acceptable values, without incurring major costs for repair or replacement. The working life of a product depends upon its inherent durability and normal installation and maintenance.
A clear distinction has to be made between the assumed economically reasonable working life for a product (also called: design working life), which underlies the assessment of durability in Technical Specifications, and the actual working life of a product in a works. The latter depends on many factors beyond the control of the producer, such as design, location of use (exposure), installation, use and maintenance.
Technical Specification writers will have to take a view about the “normal” working life of the products that they deal with. The assumed working life of a product should take account of the assumed working life of the works, the ease and cost of repair or replacement of the product, maintenance requirements and exposure conditions.ISO 17745 pdf free download.
