Definitions

  • the present invention relates to avalanches, stone chipping or logging with at least one net fastened with its upper edge to a suspension cable and with its lower edge to a floor cable guided near the ground, with supports supporting the suspension cable at a distance from the ground and with a predetermined distance Cable pulling force the extension of the suspension cable and the floor cable, with energy absorption, in the network area lying cable brake elements, at least two suspension cables (8, 9) having at least two suspension cable areas and at least two floor cables (12, 13) having at least two floor cable areas are provided and that Net (18) is successively fastened to another suspension cable (8, 9) in each of the row of suspension cables arranged in a row and successively connected to a different floor cable (12, 13) in each of the row of floor cables arranged and for each Au Suspension rope (8, 9) and cable brake elements (14, 15, 16, 17) provided for each floor rope (12, 13) on suspension rope areas of the suspension ropes (8, 9) free of the net (18) and on floor rope areas free of the net (18) the floor cables (12
  • a safety fence of the type mentioned above is already in use. With this safety fence, both the two suspension ropes and the two floor ropes intersect between two adjacent supports. The crossing ropes are brought together at the crossing points. The attachment of the net changes from one to the other suspension rope and from one to the other bottom rope at each successive crossing point in the row.
  • the suspension rope areas of the suspension ropes that are free of the network and the floor rope areas of the floor ropes that are free of the network are guided on the supports and carry cable brake elements.
  • This safety fence is usually used to secure traffic routes, such as roads, railways or waterways, but can also be used outside the areas of traffic routes to protect people, animals or buildings. If the well-known safety fence is very steep and high mountain slopes with an above-average drop height or in general in places where masses with above-average kinetic energy have to be collected, this safety fence cannot fully fulfill its task.
  • the ropes carrying the net are namely at the intersection where the net is attached to each other and not on fixed supports. For this reason, large rope extensions can occur, which cause the tensioned net to collapse not only in the stressed collection area, but also in the neighboring unstressed areas.
  • a safety fence with a plurality of rectangular nets held in a row on supports on the valley side is known.
  • the edge meshes of each net are attached to an edge rope that frames the net.
  • the four corners of the edge rope are coupled to net holding ropes that slide over the adjacent two supports at the top and bottom.
  • the net holding ropes are braced on the mountain side from the supports with the interposition of cable brake elements on floor anchors.
  • the floor anchoring point and the cable brake elements are located in the mountain-side danger zone of the safety fence. If a rope hits, the cable brake elements run out, so that the net curtain immediately loses its protective height. If the rope hit even breaks the rope, the protection fails completely.
  • the object of the present invention is to develop a safety fence that can safely absorb avalanches, rockfalls and long wood slides with above-average kinetic energy, which can easily be made operational again after catching avalanches, stone chips or logging and is economically advantageous.
  • both the two suspension ropes and the two floor ropes each run parallel to one another and are longitudinally displaceable independently of one another on each support and the suspension rope areas of the suspension ropes and the floor rope areas of the floor ropes lie between two adjacent supports, within the individual suspension and bottom rope areas, the network is attached to ropes without cable brake elements and the cables carrying the network have cable brake elements directly in the next adjacent areas.
  • the spacing of the supports can also be chosen larger, which on the one hand reduces the likelihood of the supports directly falling due to falling masses and on the other hand achieves economic advantages. It is also advantageous in terms of the assembly of the safety fence if the suspension cable areas of the suspension cables and the floor cable areas of the floor cables are located between two adjacent supports.
  • the floor cables can be guided on the foot parts of the supports.
  • floor-anchored guide elements can be provided for the floor cables connected to the network than supports are available.
  • the floor cable connected to the network can be guided near the floor between two supports by means of floor anchors.
  • a rope can be inserted between the floor rope and the floor anchor Cable brake element can be arranged.
  • a safety fence is shown schematically in the front view.
  • Fig. 2 shows this safety fence in a simply indicated steep slope from the side.
  • the fir trees shown schematically in this figure have a purely symbolic character and, in particular, do not provide any information about the scale relationships with the safety fence.
  • the supports 1, 2, 3, 4 lead at their upper end region at a distance from the floor two suspension cables 8, 9 which are braced laterally on the floor anchors 10 and 11.
  • the suspension cables 8, 9 are guided in the supports 1, 2, 3, 4 in a longitudinally displaceable manner.
  • On the foot parts of the supports 1, 2, 3, 4, two floor cables 12, 13 are guided in a longitudinally displaceable manner near the floor.
  • Both the suspension cables 8, 9 and the bottom cables 12, 13 are equipped with cable braking elements 14, 15, 16, 17.
  • the safety fence shown in FIGS. 1, 2 and 3 is equipped with two suspension ropes (8, 9) having three suspension rope areas and with two floor ropes (12, 13) having three floor rope areas.
  • the suspension rope areas and the floor rope areas lie between the adjacent supports 1 and 2, 2 and 3, 3 and 4.
  • a network 18 of wire rope is provided, which is intended for catching avalanches, stone chips and logging.
  • This net 18 is fastened to a different suspension rope 8, 9 in each successive suspension rope area and is connected to a different floor rope 12, 13 in each successive floor rope area. So it is fixed between the supports 1 and 2 and 3 and 4 with its upper edge on the suspension cable 9 and connected to the lower cable 13 at its lower edge. Between the supports 2 and 3, the network 18 is attached to the other suspension cable 8 and connected to the other floor cable 12.
  • the cable brake elements 14, 15, 16, 17 are inserted into the suspension cable 8, 9 or floor cable 12, 13 which is free of the network 18. So the cable brake elements 14 and 16 are inserted between the supports 1 and 2, or 3 and 4 in the suspension cable 8 and in the bottom cable 12. Between the supports 2 and 3, however, the cable brake elements 15 and 17 can be found in the suspension cable 9 and in the bottom cable 13.
  • the most accurate possible ground adaptation is sought for the net 18.
  • This precise floor guidance is generally achieved by providing more floor-anchored guide elements than supports 1, 2, 3, 4.
  • the network 18 is additionally guided between the two supports 2 and 3 via the floor cable 12 by a floor anchor 19.
  • a cable brake element 20 is arranged between the bottom cable 12 connected to the network 18 and the bottom anchor 19.
  • the safety fence works as follows: It is assumed that a large stone falls into the net 18 between the supports 2 and 3. In this case, the net 18 will extend downward in this area and take along the ropes, the suspension rope 8 and the bottom rope 12, which hold the net 18 in this area. These ropes have to give way and absorb the impact of the stone by absorbing energy.
  • the ropes carrying the net 18 Suspension rope 8 and bottom rope 12 are not stretched between the supports 2 and 3 when the stone mentioned is caught in the catchment area, as a result of which possible network tears can be avoided.
  • the rope attached to the ground anchor 19 is connected via the cable brake element 20 to the bottom rope 12 carrying the net 18, so that the bottom rope 12 can also expand downward at this point and does not tear.
  • the cable brake element 20 also draws energy from the network 18 and contributes to damping the impact of the assumed stone. Since the pivotable supports 1, 2, 3, 4 are attached to the floor anchors 6 via cable brake elements 7, these cable brake elements 7 will also respond to energy absorption when a large, high-energy mass hits the network 18 and allow the retention cables 5 to be extended. The restraint ropes 5 thus also contribute to damping the impact of the assumed stone.
  • the processes are similar when masses with high kinetic energy strike one another or between several supports 1, 2, 3, 4.
  • the safety fence can cause avalanches, stone chips and catch logs with above average kinetic energy. It is essential that the cable brake elements are arranged in the immediate vicinity of the cable parts carrying the net, in order not to unnecessarily stress the supports and power packs located outside the catchment area.
  • the masses collected by the safety fence must be removed from the network 18 at the latest when the cable brake elements are fully extended.
  • the ropes stretched when collecting a large mass, suspension ropes 8, 9, floor ropes 12, 13, retaining ropes 5 must be tensioned again and the extended cable brake elements 7, 14, 15, 16, 17, 20 must be replaced.
  • the replacement of the extended cable brake elements 7, 14, 15, 16, 17, 20 is particularly simple because these elements are connected to exposed cables, mostly via easily detachable cable coupling elements. The operational readiness of the safety fence can therefore be easily and inexpensively restored.
  • a safety fence with the claimed features can also be designed with rigid instead of pivoting supports.
  • the restraining cables are generally not required.
