Definitions

  • the innovation concerns an avalanche protection element.
  • Avalanche barriers consist of avalanche arresting devices which are formed from a wire rope network, this wire rope network consisting of a large-mesh network of strong ropes, which is also intended to catch large boulders of rock and ice, and a fine-mesh, thin-wire network placed over it, which To prevent the flow of loose snow avalanches or small pieces of scree.
  • These nets are often so heavy that they can hardly be brought to their installation site by human power without a motor vehicle and thus thwart the actual purpose for which snow fences are formed from nets, namely the lightness and the easy transportability.
  • snow fences for example drift snow walls or snow bridges consisting of beam grids, which are firmly anchored in the ground.
  • Beam gratings only provide the avalanche with a surface perpendicular to the direction of movement, whereby even with slight deviations of the beam gratings from this perpendicular, the avalanche can slide off the beam gratings and thus the effect of the fence is canceled.
  • Beam gratings of this type must have a large width of an endangered in order to be effective Slopes.
  • a snow avalanche protection fence which consists of tubular posts and resilient, light weight suspension devices suspended from them.
  • this fence must also extend over a large width of a slope in order to be effective. This makes passage for animals and also for humans more difficult or impossible.
  • the fence is relatively expensive to manufacture.
  • the innovation has the task of creating an avalanche protection element that is easy to manufacture, transport and assemble and that can be used to implement an avalanche protection system that does not represent a significant obstacle for animals and humans.
  • this object is achieved by an avalanche sheeting element with two plates which are vertical or inclined towards the vertical, which are made of a rigid material and which are arranged at an angle to one another.
  • the avalanche sheeting element according to the invention offers the advantage that avalanches made of snow or debris are cut up, slowed down and finally stopped.
  • An arrangement of the avalanche sheeting elements according to the invention in a network with one another is particularly effective.
  • the avalanche control elements do not block any passages on the slope, but leave openings open so that animals and people can pass through the secured terrain relatively unhindered.
  • the individual avalanche control elements can be arranged in such a way that they disturb the landscape and nature only slightly or not at all.
  • Trees can easily be reforested behind the individual elements, as the elements offer good protection.
  • the parts of the avalanche control elements are preferably hot-dip galvanized and can then be painted as required for the purpose of protecting the landscape and rust. Individual elements are better blown away by the wind than large-area connected structures, such as large fences.
  • the plates of the avalanche barrier element advantageously have openings in order to give small amounts of snow or scree an opportunity to slip through. This reduces the surface load on the panels.
  • the two plates can consist of a single piece of metal or plastic that is bent to achieve the angular arrangement of the two plates. In this way, an avalanche sheeting element according to the innovation is particularly easy to manufacture.
  • the two plates can also be produced separately and connected to one another at the installation site by known types of connection such as screwing, riveting, welding or gluing. You can also make the abutting edges of the plates so that the plates can be hooked together and thus no further connecting elements such as screws, rivets or the like are required.
  • the avalanche control element is advantageously anchored in the ground. This anchoring is often sufficient in areas where experience has shown that avalanches are only emerging. An avalanche control element then prevents the initial movement of a snow or rubble mass, which prevents the formation of avalanches.
  • an avalanche sheeting element has guy devices in order to be able to catch avalanches that have already arisen.
  • a guy are z. B. chains, ropes or rods, which - if arranged at occupied heights - hold the elements and at the same time cause a division in the horizontal plane. Since such avalanches can apply a surface pressure of up to 40 t / m 2 , simply fastening them in the ground is often no longer sufficient to safely catch the avalanche.
  • Another advantage of the guy devices is that they cut and break up avalanches in motion and thus further reduce the possible pressure on the avalanche installation element.
  • a further advantageous possibility for the stabilization and safe installation of an avalanche control element is provided by a support which supports the avalanche control element on the side facing away from the avalanche opposite the ground.
  • An avalanche sheeting element provided with anchoring devices can also be set up in the most difficult buildings, where previous structures cannot be installed.
  • the innovations can be in any width, for. B. from 1.0 - 4.0 m width and heights, z. B. up to 3 m, so that a good adaptation to the local conditions is possible.
  • the avalanche control element 1 shows an avalanche sheeting element 1 from the side facing an expected avalanche. This page is common certainly uphill.
  • the avalanche control element 1 consists of two plates 2, 3, which are made of metal, plastic, wood or another rigid material.
  • the plates 2, 3 have openings 4 through which a small amount of snow or debris can reach the side of the plates 2, 3 facing away from the avalanche, thereby reducing the pressure on the avalanche barrier element 1.
  • the two plates 2, 3 are vertical or they are inclined with respect to the vertical. They are arranged at an angle 6 to each other. This angle 6 opens in the direction from which an avalanche can be expected.
  • This arrangement can be achieved in that a plate 2 is screwed together with a plate 3 at an edge 10.
  • Other types of connection such as welding, riveting or gluing, are also conceivable.
  • Another possibility is to bend a single slab, the total area of which is equal to the sum of the areas of the two slabs 2, 3, at the edge 10, so as to obtain the avalanche barrier element 1.
  • Such an avalanche sheeting element 1 is particularly simple to manufacture and the connection of the two plates 2, 3 has a high strength.
  • guy devices 5 On the mountain side of the avalanche barrier element, that is the side on which the angle 6 is enclosed by the two plates 2, 3, one or more guy devices 5 are attached. In the illustrated embodiment, four guy devices 5 are shown. The guy devices 5 are arranged in the vicinity of the vertical edges of the avalanche barrier element 1.
  • the guy devices 5 can be designed as chains or ropes. Other devices, such as tension bars, are also possible.
  • the avalanche sheeting element 1 has connecting devices 7 which mate with counterparts 8 of another avalanche shoring element 1 can be brought into engagement. This makes it possible to create a system of avalanche barriers which are connected and braced to one another by means of the connecting devices 7 and the counterparts 8. As a result, the avalanche barriers 1 can support and secure one another.
  • the connecting devices 7 and the guy devices 5 can have turnbuckles in the usual way.
  • F ig. 2 shows an avalanche sheeting element 1 from the other side, ie from the side facing away from the avalanche to be expected.
  • a support device 9 supports the avalanche sheeting element 1 from the side facing away from the avalanche. In the illustrated embodiment, only a single support device 9 is shown. However, any number of support devices 9 are possible. These support devices 9 are attached to the avalanche barrier element, for example by screwing, welding or riveting. It may be expedient to merely wedge the support devices 9 with the avalanche sheeting element 1.
  • a guying device 5 or a support device 9 is used for fastening and stabilizing the avalanche control element on the slope depends on the operating condition of the avalanche control element. In principle, both safety devices are possible, and can also be used together.
  • Fig. 3 shows the use of several avalanche barriers 1 on an avalanche-prone slope, the direction of movement of the avalanches being indicated by downward-pointing arrows.
  • the snow or rubble masses do not collide head-on with one that is transverse to the direction of movement Surface, but are broken on the outer edges of the avalanche building element 1. This reduces the initial pressure surge on the avalanche barrier element 1.
  • the impacting snow or rubble masses are held in the following by the plates 2, 3 of the avalanche sheeting element 1 arranged at an angle to one another, so that an alignment of the avalanche sheeting element 1, which is not exactly perpendicular to the direction of movement of the avalanche, does not include the risk of the avalanche slipping .
  • the avalanche shoring elements shown in FIG. 3 have a plurality of plates 2 and 3, one above the other, which can optionally be provided with holes 4. If further masses of snow or scree follow, a wedge of snow or scree is created above the avalanche barrier element 1, on which the avalanche splits and splits itself. The interaction of several avalanche barriers 1 can be achieved by gradually braking the avalanche.
  • the avalanches are also generally cut and slowed down by the connecting devices 7, with which individual avalanche construction elements can be connected to one another.
