Steel wire mesh main components: Bolt: general use Φ25 / 28 common thread steel bolt end (exposed section) with a processing thread, may also Φ25 finishing rebar (eg GEWI anchor), and according to the need for Redu Zinc corrosion treatment, can be difficult to enter into the hole from the time hollow bolt; boundary line: optional part. When considering the complex terrain boundary or boundaries need to improve the effect of the choice of closure, Φ12 or Φ16 galvanized steel wire, single length of not more than 40M, with one at each end of each length of 2-3M of double-stranded wire rope anchor 2Φ16 . Auxiliary anchor: optional part for making the grid in the local low-lying or better tight boundary posts slope, the same configuration with the main anchor, but slightly smaller diameter, usually 20-25mm, length is generally used in a -1.5M; Driven anchors: selection of pieces for soil slope to the grille in the local low-lying live better tight boundary posts slope, it is appropriate Φ16 steel, length is generally 0.3-0.6M, end Welding hook. Design parameters and material configuration: protection areas: general should extend existing or potential damage area at least 1m above; bolt spacing a and b: 2-4m, standard spacing of a = 3.3m; b = 4m; prestressed P : There is regional instability press 30-50KN slide design, tighten the nut so that only protective grille slope close as possible to the time weathering or rockfall; bolt length L: According to the need to design, but not less than 2.15 m, and generally 2.15-3.65m (exposed length of 10-18cm), should anchor slip boundary less than 1m long, and to ensure that no small pullout less than 40KN or 1.3P; bolt diameter D: According to the need to design, general To 25-28mm, ensure a single rod breaking force is not less than the anti-100KN or 3P; bolt inclination: general should be dry drilling, aperture should be larger than the bolt diameter 12mm or more; suture wire or rope: Portrait grid connection between blocks long using the same type of knitting with the grid wire Corrugated suture silk suture, lateral connections between the blocks 8 mesh galvanized wire rope or wire grid woven with the same model, the path length of about suture line length of about 1.2 times. Matting board: the number of identical number of anchor roots, and with special nut. Optional components: according to the design needs to be configured.
