  • the installation of the device can be done with a few people or from boats or vehicles.
  • the devices may be removed, rolled up, cleaned, and deployed for further use.
  • the devices when fitted with a float, can be routed along the facades of buildings and lift with increasing water levels, thereby preventing the entry of dirt, mud and debris into the buildings. The entry of water can not be prevented; these But damage is significantly lower than those of incoming solids. It can be protected in this way whole street trains or individual houses.
  • the attachment of the device is simple and can be done within a few minutes by the fire department or the homeowner itself.
  • the device If the device is used on banks of rivers or dams, so their installation can take place within the early warning and in a short time.
  • the device not only protects the submergence of the dams and / or banks, but it can also be achieved with it an increase of the dam by 40cm, 60cm or 80cm.
  • the laying is very simple and can be done directly from a vehicle, and the attachment of the device in the bank or in the dam can be done as necessary by piles.
  • the device may be stabilized by flooding chambers therein or by inserting ballast bodies.
  • one or more devices can be placed in the slope and secured by piling.
  • Material of the device is an ingrowth with the substrate or a successive biodegradation done.
  • the slope is protected by the device during growth of the young plants; after growth, the rooted plants serve as slope and slope protection.
  • the water flowing in on the slope can either be led out of the slope area within the tubular body or in the apron designed as a gutter or can be specifically collected and removed.
  • water may be supplied through the tubular body during drying times and may be dispensed drop by drop through small openings for humidification to the substrate, for example an embankment. From a drainage an irrigation system is created in this way.
  • the devices can, if they are provided with buoyancy bodies, similar to oil barriers, used as a propellant barriers for the protection of reed areas or nature reserves.
  • the device shown in Figure 1 shows a finite barrier section 1 of length L, the construction of which is based on those of floating oil barriers, as known for example from CH-A-686685 and FR-A-2 633 274, respectively.

  • a barrier portion 1 is shown, which is to secure a dam 39 or bank embankment on a body of water (flowing or standing) 41, shown.
  • the upper portion of the barrier portion 1 with the solids 5 in the tubular part 3 is located on top of the crown of the dam 39 and additionally increases this by an amount h, which corresponds to the diameter of the solid 5.
  • 5 materials are used as a solid, which have a lower specific gravity than water and, of course, can not be saturated with water.
  • the barrier section 1 is held with safety ropes 43 and mounting posts 45 to the crown of the dam 39.
  • the skirt 7 abuts against the slope 47 and is pressed by the flooded chambers 17 to the latter.
  • tension elements 15 preferably chains with high weight.
  • additional retaining clips or textile loops 49 may be attached to the tubular areas 3. These can also serve as carrying handles when the device is misplaced or packed together.
  • the chambers 17 fill, so that lifting the apron 7 or the additional aprons 7 'is excluded from the bank area by wave or running water.
  • the dam 39 can be protected with a few barrier sections 1 over a shorter or with a larger number of barrier sections 1 over a greater distance against under-flushing and / or flooding.
  • the Block sections 1 can be laid in or out of the water 41 already before the rain event, if this is expected, or even at a later time from the crown of the dam 39 on or from the shore.
  • Temporary below the aprons 7 coming fauna is probably compressed by the pressure of the water; but it is not destroyed, either by leaching, slipping or other foreign interference such as laying stones, plates, etc.
  • the material for the skirt 7 may be permeable to water or impermeable.
  • the barrier sections 1 are used to secure slip-prone slopes, where by heavy rains the protective, rooted by roots surface (turf 55) can slip off.
  • the barrier sections 1 are anchored in this application with stakes 51 or pipes in slope 53.
  • the tubular area 3 is - in contrast to the river bank - below; the skirt 7 extends upwards. This creates a stepped surface.
  • the piles 51 can below the filled with solids 5 tubular areas. 3 lie and support them, or they can as shown in Figure 8, the aprons 7 penetrate, and the tubular portions 3 are then attached hanging.
  • the aprons 7 may be loaded by water-filled chambers 17 or rest by their own weight on the ground.
  • the illustration in FIG. 9 shows the securing or erosion barrier in the region of an erosion crack at the upper end of a slope.
  • the remaining turf 55 is already undermined, and the tubular portion 3 is placed under the undermined turf 55 and with piles 45 and possibly additionally on the tension element 15, which is also secured with mounting posts 45, held.

But it is also possible, in the tubular portion 3 through the volume body 5 through a pipe 57 to pass through which fastening piles 45 can be performed. As a result, the barrier section 1 can be held directly by the fastening pile 45 (FIG. 11).
  • the vegetation may continue to thrive through the skirt 7, or plants may be planted through the skirt 7, eg pastures or other fast-growing shrubs or grasses.
  • the skirt 7 then serves as a reinforcing grid.
  • a decomposable or biodegradable material be it natural fibers or man-made fibers that are biodegradable, can be used as the apron material.
  • a slope and slope protection is shown, which consists of a single barrier section 1, which is secured with continuous mounting posts 45. With this device, a local break-off point can be secured, wherein the upper barrier portion 1 protects the tearing area at the end of the turf 55; the lower barrier section 1 serves as a collector for slipping material 59.

  • short skirt portions 61 are provided on both sides of the tubular region 3, to which additional skirts 7 ', as shown in FIGS. 2-4, can be fastened if required.
  • additional aprons 7 'eyelets 23 are provided for the attachment of the additional aprons 7 'eyelets 23, as already described above.
  • the solids 5 have different properties, which depend on the art the barrier sections 1. For use as erosion protection in waters and dams closed-cell foams are preferably used, which can not absorb water and swim with increasing water on this. For use as erosion protection in slopes, there are materials that can not absorb or flow through water. For definitive slope stabilization, materials are used which rot over one, two or more years and become overgrown and / or ingested by the root system. It is therefore also possible to introduce 5 seeds in the solids, which can sprout plants whose roots contribute to the slope protection.
  • the solids 5 may be formed as a solid body ( Figure 14) or tubular.
  • connection means for FIG. 1 for connecting individual barrier sections 1, it is of course possible to provide all connection means be as they are for oil barriers in use.
  • erosion and flood barriers can be combined with oil barriers. It can be seen that the handling of the erosion and flood barriers is related to that of the oil barrier and also in the same manner on reels are transportable.
  • the barrier portions 1, as shown in Figures 1 to 3, can be used to protect buildings in flood.
  • the barrier sections 1 are attached to the floor along house walls at the lower edges of the aprons 7. With increasing water level, the solids 5 in the tubular areas 3 lift the barrier sections 1 upwards and thus prevent the entry of solids (scree, mud, stones) into the interior of the houses.
  • These made of very tear-resistant material barrier sections 1, which are also reinforced by the tension elements 15, at high tide in stagnant water, or if the aprons 7 consist of networks, are introduced into flowing waters to shore areas, reed areas or nature reserves from driftwood and to protect the like.
  • hose-shaped area 3 and possibly the subsequent apron 7 floated on the water floating oil as is usually done with the floating oil barrier known type. However, they are not trained to stop driftwood.
  • a cavity 61 is formed in the tubular body or region 3 in the area of the lower vertex, into which water enters through holes or loops 63 and can be discharged along the tubular body or region 3 from the slope or embankment area , Alternatively, water may be added during dry times for irrigation of newly planted slopes or reclamation of washed-out slopes and discharged dropwise through the holes 63.
  • a water-bearing channel 65 can also be formed with the skirt 7 (FIGS. 17 and 18). Along the free edge 67 of the skirt 7 means, such as eyelets 69 or rope loops 71 are attached, with which the skirt 7 can be raised.
  • two tubular body 3 serve as boundaries of a crown of a dam.
  • the two bodies 3 may be connected to each other on the crown by a skirt 7.
  • Additional aprons 7 can protect the slope 73 at least in the crown area against erosion.
  • Through the fine holes 63 can dropwise water to moisten the embankment in Dry times are delivered.
  • the side edges 9 are formed by tubular or rod-shaped stiffening elements 81, which extend substantially between the two tension members 15.
