The cylindrical gabions are cylindrical structures made from double twist 8×10 cm hexagonal wire mesh with mechanical properties greater than those specified in UNI-EN 10223-3, certified in accordance with the “Guidelines to draw up specifications for the use of double twist wire netting” issued by the National Public Works Council – Central Technical Service (Certified Product No. 226/001).
These elements are adopted for the protection of banks and embankments, for the construction of gravity support works, for retaining unstable slopes which have a “substantial structural importance” and, as such, must have the requirements specified in the Technical Standards for the Works under Ministerial Decree 14 September 2005 and subsequent amendments.
The cylindrical gabions are filled with stones on site to create a flexible and permeable structure to be used for river bank protection works and emergency works. The cylindrical gabions are fitted with reinforcement bars inserted in the mesh during manufacture to facilitate the closing during installation.
