lower hold type mattress for protective structures coating applicable to superifici of land subject to erosion

摘要

A mattress-type gabion for ground stabilization is formed from a base sheet of wire mesh by providing the sheet with folds from spaced apart transverse ribs and having the panels of the folds tied together at transversely spaced locations along each rib. Cuts in the base sheet flanking each rib zone can define other folds which can be tied to the ribs when edge strips of the sheet are folded up, thereby forming stably upwardly open compartments which can be filled with ballast and then closed by a mesh cover.
