摘要:
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.

A production plant for a ground covering structure (6) comprises a plant inlet zone and a plant outlet zone for a grid reinforcing member (10). The plant further comprises movement means (4) designed in operation to move the grid reinforcing member (10) along a predetermined path from the inlet zone to the outlet zone, supply means (11) for the supply of plastics material in the fluid state in the form of threads (7) to the reinforcing member (10) disposed along the predetermined path, and cooling means (2, 3) for cooling the plastics material in the form of threads (7) which are tangled on the grid reinforcing structure. The inlet zone and the outlet zone are disposed opposite one another along the predetermined path with respect to the supply means.

A reinforcing device for earthworks comprises at least one reinforcing base element (3) from which extend a front wall (9) and a containment wall (15) which are spaced from each other to delimit, in an operative configuration in which they are erected with respect to the reinforcing base element (3), a facing region which is to be filled with filling material, such as stones or the like. The device also comprises bracket means (23) which can be coupled, in use, to the front wall (9) and to the containment wal (15) It is also possible to produce a second front wall which extends from the reinforcing base element (3) on the side opposite the first. A method for the production of a reinforced earthwork provides for laying on the ground a device of the type indicated.
摘要:
A lightweight protection element and filter of the mattress type comprises an external containment structure (10, 20) , a three-dimensional internal structure (30) with a high cavity index and a granular filler material which is inserted inside the containment structure. Engagement means (50, 52) of the mechanical type are distributed over the external containment structure in order to engage predetermined portions of those structures with each other.
摘要:
A modular greened sound-absorbing structure is formed by one or more containment sections (2, 4, 6, 8, 10, 12) for filling material in which plant material can be cultivated. Each containment section comprises frame means (20), connecting means (30, 32) engaged with the frame means in order to connect those frame means to one another, and a plurality of wall means (40) engaged with the frame means in such a manner as to define at least one pair of lateral walls of one of the above-mentioned containment sections. Finally, the containment sections are filled completely with the filling material.

A soil-covering structure comprises layers (10) of geocomposite which enclose a reinforcing element (20) and which are engaged with the latter at predetermined positions only.
摘要:
A process for the manufacture of a protecting and immobilising element of the mattress-like type consists in providing containing means (2, 20) and a layer of flexible material (3, 21) inside them, with the peripheral edges (4, 22) of the flexible layer (3, 21) protruding from the containing means (2, 20). Anchoring means (5) and a first netting structure (6, 23) are also arranged inside the containing means (2, 20) so that the netting structure (6, 23) is in direct contact with the flexible layer (3, 21) and the anchoring means (5) pass through the netting structure at predetermined positions (12, 25). The containing means (2, 20) are then filled with a filling material (7) comprising solid and/or fluid elements, and a second netting structure (8) is superposed on the filling material. Finally, by superposing, at least partially, the peripheral edges (4, 22) of the flexible layer (3, 21), a closed cover is produced from which the ends (11, 27) of the anchoring means (5) protrude.
