Definitions

  • the invention relates to a device for protection against masses which slide off from a higher point, in particular against avalanches or mudflats, with a retaining device provided in the path of the mass flow, which comprises at a distance in the direction of the mass flow lined-up, transversely to the mass flow, water-permeable barriers ,
  • the invention is therefore based on the object, a device of the type described above to protect against sliding off of a higher point bodies, especially avalanches or muds, so that the particular associated with the clearance of successive locks difficulties of restraints can be avoided.
  • the invention solves this problem by the fact that the locks are at least gradually brought from a blocking position into a downstream open position.
  • the advantageous condition is created to clear the restraining device from below sections of lock to lock, without running the risk that put all the collected by the retainer masses in motion, because only the each lowermost barrier is opened so that the overlying locks maintain their supportive effect.
  • the clearing of barriers in the region of a channel is supported by flushing out of the accumulated masses of feinkörnigerem material that can be discharged through the open lock with the help of the channel.
  • the spaced-apart barriers also allow a dynamic collection of the mass flow, if the individual locks are provided with different levels of retention fuses.
  • the blocking positions of the locks can be secured by predetermined breaking points, which have different breaking loads if necessary.
  • the individual barriers can be adapted with regard to their retention behavior to the composition of the respectively expected mass flow, for example by an appropriate choice of the mesh size of grids or nets.
  • the barriers may have side parts which extend inclined from a middle section in the flow direction, so that the overflow over these side parts has a pronounced flow component towards the center of flow, which relieves the flow of the bank areas and thus one lower risk of erosion for the embankments.
  • the barriers arranged one behind the other can be opened from the lowest beginning one after the other in order to facilitate the clearing of the barriers, wherein finer-grained attachment parts are washed out of the accumulated material by the channel.
  • the locks may have a central section which can be opened downstream for itself and which, after its opening, causes a collection of the channel and thus an increased discharge of the material due to the then lower flow resistance in this central section.
  • the barriers may but need not extend the full width of the mass flow path. If the barriers, which are arranged one behind the other at a distance in the direction of flow, protrude only partially into the path of the mass flow, then this becomes under a retention of a part of its flow Masses reversed and / or distracted, which creates depending on the given conditions advantageous conditions not only for the diverting or the gradual interception of the mass flow, but also for the evacuation of the barriers. In this context, it should be noted that, for example, by redirecting the mass flow with a simultaneous retention of each partial mass, a considerable part of the energy of such a mass flow can be reduced. In addition, the discharge of finer-grained mass fractions is supported before the barriers are opened for evacuation purposes. A channel remains a meandering bypass of the barriers open.
  • the protection device which is arranged, for example, in a channel 1, has a retaining device comprising a plurality of water-permeable barriers 2 arranged in series in the course of the channel 1 in the form of a grid, a net, a rake or the like.
  • This anchored by means of anchors 3 in the underground barriers 2 are held by traction cables 4, which are braced over embankment anchor 5, in a blocking position.
  • the mass flow moving along the channel 1 is absorbed by the barriers 2 which are connected in series in the direction of flow, whereby a part of the mass flow is retained by the barriers is, while the rest of the mass flow pours over this barrier 2 away to the next downstream barrier until the residual mass can be completely absorbed by a barrier 2 or the bottom lock 2 overcomes.
  • This stepwise interception of the mass flow occurring in the event of an event can be supported by a dynamic support of the barriers 2 via the traction cables 4.
  • the traction cables 4 can be connected for this purpose, for example via predetermined breaking points 6 for different breaking loads with the slope anchors 5.
  • the barriers 2 are to be evacuated after a Mur Francisco or an avalanche, this can be carried out advantageously from the lowest progressive to the top of the barrier 2 by the blocking position of the respectively to be cleared barrier 2 is opened downstream.
  • the connection points 7 of this lock 2 can be achieved with the tension cables 4, so that the barrier 2 to be cleared can be swung against the channel bottom, as indicated in FIG. 1 by the arrow 8.
  • the limited mass accumulated between the open barrier 2 and the upstream barrier 2 can thus be removed downstream in a comparatively simple manner, without having to fear that the masses retained by the remaining barriers 2 will slide off.
  • the subdivision of the barriers 2 in a central portion 9 and two side parts 10 also brings with it the advantage that initially only the central portion 9 can be opened when 9 corresponding closures 13 are provided in the region of the central portion.
  • the ability to initially open the central portion 9 allows a large flushing out of smaller accumulated parts from the accumulated mass, because the channel can be collected in this central portion due to the lower resistance to flow after the opening, depending on the extent of the opening also in different layer heights. It then only need the remaining coarse parts of the accumulated masses to be removed.
  • Fig. 4 it is indicated that the barriers 2 need not extend over the entire width of the expansion of the mass flow in order to fulfill an effective protective function can.
  • the mass flow sliding downwards, for example, along a channel 1 is forced into a deflection by a barrier 2 protruding only in part into the flow path, as is illustrated by the flow arrow 14. Since at the same time part of the mass flow is retained by the barrier 2 and accumulates upstream of the barrier 2, the energy of the mass flow is correspondingly reduced.
  • the effect is further enhanced until the mass flow is reduced at least to a harmless level or is diverted from the areas to be protected down to the valley.
  • the gutter can after the interception of the mass flow his way according to the flow arrows around the barriers 2 outside and while doing away with smaller bedding parts, so that the washed-out bedding parts no longer have to be considered in the clearance of the barrier 2.
  • the evacuation itself can be carried out in sections from lock to lock starting with the lowest lock 2, as has been described in connection with FIG.
