Abstract: A block for a retaining wall having a front face forming part of a visible side of a retaining wall, and a support face which supports at least one similar overlying block. The support face is angled with respect to the front face and traversed by a through opening which defines an internal abutment surface placed at a first predetermined distance from the front face. A reference element protrudes from the support face at a second predetermined distance from the front face, in order to abut, in use, against the at least one internal abutment surface of the similar overlying block and thus prevent the displacement thereof in only one of two directions which are transverse to the front face. The reference element includes a flattened engagement portion. An elongate slot is provided on the support face to receive the corresponding flattened engagement portion.

Abstract: A device for twisting plastic wires to form a plastic open mesh net comprises a front twist mechanism and a back twist mechanism which have corresponding pairs of front and back thread-holes for receiving plastic wires to be twisted. Each couple of a front thread-hole and a back thread-hole is connected by a corresponding heat-conductive thread guide, preferably in the form of a pipe, which provides a uniform heating of the plastic wire which is guided therein. A machine for manufacturing a plastic open mesh net comprises a holding device downstream of the twisting device to maintain a uniform shape of the just formed open mesh net.

Abstract: 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 neighbouring 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.

Abstract: A system for metering and adding fibres to a cement matrix comprising means (3) for supplying the fibres and means (5) for conveying the fibres designed to convey them, in use, from the supply means (3) to the cement matrix. The conveyor means (5) are closed with respect to the surrounding environment. The present invention also relates to a method for metering and adding fibres to a cement matrix comprising the stage of supplying predetermined quantities of fibres by means of a supply device (3), and conveying these predetermined quantities of fibres from the supply device (3) to a predetermined position while keeping these fibres isolated from the surrounding environment.

Abstract: 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.

Abstract: A wave-motion reducing structure comprises wave-motion reducing means (30) suitable for being laid on a coastal bed and restraining means (20, 22) suitable for restraining the wave-motion reducing means on the coastal bed. The wave-motion reducing means (30) are arranged so as to be inclined, in use, against the direction of the sea current which strikes them. A wave-motion reducing system comprises a plurality of wave-motion reducing structures arranged in a row lengthwise and in a manner such that the wave-motion reducing means (30) adopt a substantially parallel configuration and oppose the motion of the current.
