摘要:
An anchoring member (15) capable of being integrated into a facing element (10) for the creation of stabilised earth structures, comprising a shell (21) that defines a recess (18) with a mouth (13). An anchoring bar (20) extends transversely within the recess (18) in such a way that, in use, an elongated stabilising member for stabilised earth structures, such as a strip or similar, can be made to pass around it by inserting it into the mouth (13).

A protective metal netting comprises a plurality of longitudinal metal wires or cables (10) side by side, each interwoven with at least one adjacent longitudinal wire or cable (10) in an interweave portion (24), in which at least one of the metal wires or cables (20) has an almost rectilinear development, or in any case with loops that are less pronounced than the lower-strength neighboring cables. A machine for manufacturing interwoven metal nettings comprises a cylindrical drum (50), on the outer surface of which a plurality of pins (52) protruding radially and arranged in axial rows at equal angular intervals is fixed, with an equal pitch in all the rows. Some pins (54) present on the cylindrical drum (50) are fitted out-of-alignment with respect to the above-mentioned pitch.
摘要:
A reinforced gabion comprising two adjacent walls with a common edge manufactured using a single sheet of double twisted metal mesh fabric formed from metal wires which have two different diameters respectively corresponding to the two walls. Preferably the metal mesh fabric has a mesh with at least one twisted side formed from at least two metal wires woven together in which each twisted side is aligned in the direction of the common edge between the two walls.
摘要:
A mould for constructing a protection and securing element of the mattress type comprises an upper frame (10), a lower frame (30) and a plurality of dies engaged in the lower frame and particularly suitable during use for receiving cement material. The upper and lower frames are modular structures which each comprise a plurality of carrier elements which are selectively connected to each other, the number and/or length of the carrier elements being variable, during use, so as to vary the length and/or the width of the mould.
摘要:
Procedure for the creation of mattress gabions for soil revetments, designed to halt erosion and/or to consolidate the soil, characterised by a protective vegetable revetment consisting of the structure within the mattress which retains the soil (7) inside each individual cell. The invention allows each cell of the container to be filled with earth (7) or another earth mixture, encouraging the growth of vegetation inside the mattress in order to afford a natural protection to the soil of banks or escarpments, etc. After it has been filled, the mattress is closed by a top cover (9) in double twist steel mesh, after laying a geosynthetic (8) sheet between the two to keep in fine materials.
摘要:
An energy dissipation device with a friction rope for a protection structure comprises a plate with a plurality of through-holes and a rope which passes sequentially through the plurality of holes alternately at one side and the other of the plate in order to take up a sinuous configuration. At least one of the holes has an inclined axis with respect to the perpendicular to the plane of the plate. Additionally or alternatively, at least one of the holes is provided with a sliding bush made of a material having a friction coefficient less than that of the material of the plate. Additionally or alternatively, the plate comprises at least three holes, in which at least a pair of adjacent holes has a spacing which is different from another pair of adjacent holes.
