Abstract: A method for producing helices for a chain-link net, said helices for forming the chain-link net being interconnected, and rotated into one another, wherein the helices are produced from at least one longitudinal element, in particular a single wire, a wire bundle, a wire strand, and/or a wire rope, with at least one wire being partially implemented from a high-tensile steel, and wherein the helices are bent so that they include a plurality of first legs, a plurality of second legs, and a plurality of bending regions that interconnect a first leg and a neighboring second leg, wherein the helices are bent, by a braiding knife assembly comprising at least one braiding knife, in such a manner that at least the center points of the first legs and/or at least the center points of the second legs of a completely bent helix each lie substantially in one plane respectively.

Abstract: A corrosion protection device, in particular a corrosion protection adapter, at least for a protection against corrosion at least of an end region of a geotechnical anchor element, which is in particular realized of a corrosion-sensitive metal or of a corrosion-sensitive metal alloy, for example of a construction steel or a concrete steel, includes at least one sleeve element which is configured at least for a mounting on the geotechnical anchor element, encompassing the end region of the geotechnical anchor element at least in a circumferential direction of the geotechnical anchor element, wherein the sleeve element is made at least largely of a corrosion-resistant metal and includes at least an outer thread.

Abstract: A protective device, in particular an erosion protection device and/or a drainage device configured as a geotextile, includes a mat element, which is at least intended to be spread flat over a surface to be protected and which is formed at least to a large extent from a three-dimensional, nonwoven-like, and tangled nonwoven-like, composite with a multiplicity of fibres.

Abstract: A sensor-network-based analysis and/or prediction method for protection from natural hazards includes: receiving and collecting electronic sensor data from distributedly arranged sensor modules of an outdoor sensor network in an external analysis and/or prediction unit, the sensor data including at least outdoor corrosion measurement data, impact sensor data and/or rope force sensor data, the sensor data including at least tropospheric measurement data, and at least one tropospheric measurement dataset being, in particular geographically, allocated to each outdoor corrosion measurement dataset; storing the received sensor data of the outdoor sensor network in a memory unit of the external analysis and/or prediction unit; analyzing the received sensor data for a determination of a natural hazard risk in respective application areas of the sensor modules by the external analysis and/or prediction unit; and providing the natural hazard risk determined by the external analysis and/or prediction unit to an authori
