摘要： A safety net for rockfall protection barriers includes two outer supports anchored to the slope or rock and at least two inner supports anchored to the slope or rock. Rope guide elements are arranged at the upper and lower ends of the outer and inner supports for respectively two upper net body load-bearing ropes and two lower net body load-bearing ropes. Respectively one of the two upper net body load-bearing ropes runs through a rope guide element of the inner supports and one of the two lower net body load-bearing ropes runs through a rope guide element of the inner supports and is guided past neighboring upper and lower rope guide elements of the inner supports.

摘要： A wire netting, in particular a safety net, includes a plurality of helices which are braided with one another and at least one of which is manufactured of at least one single wire, a wire bundle, a wire strand, a wire rope and/or another longitudinal element with at least one wire, in particular made of a high-tensile steel. The wire is bendable in a reverse bend test in opposite directions, by at least 90° respectively, about at least one bending cylinder having a diameter of maximally 2 d, at least M times without breaking, wherein M may be determined (by rounding down if applicable) to be C·R−0.5·d−0.5 and wherein a diameter d of the wire is given in mm, R is a tensile strength of the wire in N mm−2 and C is a factor of at least 400 N0.5 mm0.5.

摘要： An avalanche control device includes a detonation initiator unit and a bio-degradable linear bag. The initiator unit is elongated and includes an ignition end, an inflation end, and a stepped transition zone in between that gets progressively greater in diameter as it extends from the ignition end towards the inflation end. The inflatable bag is adapted for connection to the inflation end of the initiator unit. The design of initiator unit is fixed and reusable, while the bag dimensions can be tailored to the desired blast strength for the end user, in terms of length, diameter, and mixture ratio.

摘要： The present invention discloses a combined energy dissipation scaffolding structure for preventing falling rock hazards for high and steep side slope during highway construction, which belongs to the field of prevention and cure against highway disaster and post-disaster reconstruction engineering in earthquake area. The combined energy dissipation scaffolding structure mainly comprises five parts: a top surface impact-resistance system closely jointed with the existing slope surface, a top surface support system composed of 3D stereographic steel frame systems, a scaffolding body structure composed of a cross beam and support steel-pipe posts at both sides, a mountain-side anchorage system for anchoring the top surface impact-resistance system and the scaffolding body structure, and an anchoring-type steel-plate concrete composite foundation, wherein a fixed base is welded with the bottom of the steel-pipe post and is driven in the foundation soils using anchor rods. The combined energy dissipation scaffolding structure not only can prevent potential safety hazards caused by dangerous crag falling rock at high and steep slope in a seismic region to highway construction and vehicle travelling, but can effectively improve the stability and anti-seismic capability of scaffolding structures. Compared with the traditional shed tunnel structure, the combined energy dissipation scaffolding structure has the advantage that the construction time is greatly reduced, thereby being beneficial to making road unblocked and improving anti-disaster capability.

摘要： A brake for a rockfall protection net includes a housing, at least three rolling shafts, and a metallic deformed plate. Force exerting sections of the rolling shafts are movably arranged in the housing and parallel with each other. At least one rolling shaft is not located on a same plane where the other rolling shafts are located. A first end of the metallic deformed plate penetrates into the housing from a back end of the housing and stretches out from a front end of the housing. A deformed section of the metallic deformed plate is located in the housing. The force exerting sections of al least two rolling shafts contact a first surface A of the metallic deformed plate, and the force exerting section of at least one rolling shaft contacts a second surface B of the metallic deformed plate.
