Definitions

  • the invention relates to a reinforced vegetation layer according to the preamble of independent claim 1.
  • WO-A-88/02419 discloses a mixture of soil and discrete fibers, gravel, sand, floating sand or loam being provided as soil. Such a mixture is not suitable as a vegetation layer and for greening it would have to be covered with a vegetation layer.
  • JP-A-55 36 576 a method has become known in the prior art from JP-A-55 36 576, according to which a network is stretched over the surface of this slope in order to stabilize a steep slope.
  • a layer of sludge reinforced with coconut fibers is first sprayed onto this net and another layer of water and an artificial earth material is sprayed onto it to form an artificial layer of soil.
  • the application of two different layers is complex and the layer obtained may be difficult to green.
  • the invention has for its object to provide a reinforced vegetation layer, which enables a simpler method for securing and greening steep and rocky slopes and which is characterized by high dimensional stability and cohesion with improved resistance to many types of erosion and also a safe and faster Greening guaranteed.
  • the object is achieved by the invention according to claim 1.
  • the plastic microfibers link the organic substance and thus form a rotting-free reinforcement and linkage of the vegetation layer.
  • the admixed dried sea plants form a binding colloidal mass due to the connection with water, which creates a point connection in the capillaries of the vegetation layer.
  • the clay minerals and the micro and macronutrients provide the vegetation with the necessary nutrients.
  • a single-layer structure is sufficient, that this single layer can be applied hydropneumatically and seeds can be introduced in the same operation.
  • a layer thickness of 5 to 15 cm is sufficient.
  • the plastic microfibers are preferably a mixture of fibers of different lengths with lengths between 2 and 20 cm, preferably between 3 and 8 cm.
  • the fibers are preferably branched and made from UV-stable polyester. The fine hairs of such fibers result in a felt-like concatenation and contribute significantly to the stabilization of the applied vegetation layer.
  • Fig. 1 shows a steep slope with a base 5 of weather-prone rock or stable loose rock.
  • This unstable steep slope is secured by a static network 6 made of plastic, a suitable metal or natural fibers.
  • This network is fixed with anchors 4, which have a length of, for example, 2 to 4 m, and with claw plates 3.
  • anchors 4 which have a length of, for example, 2 to 4 m, and with claw plates 3.
  • a vegetation layer 1 is applied to the secured slope surface. In the earth-moist state, this is pneumatically transported by means of tubing using suitable equipment, and water is passed through immediately upon exiting the spray nozzle. The water content of the vegetation layer 1 can thus be easily and precisely adapted to the local conditions.
  • the armored vegetation layer to be sprayed consists of an organic substance based on a compost soil with a high skeletal content, plastic microfibers, organic plant fibers with a length of about 5 to 7 cm, dried seaweed, broken opaline expanded clay balls as structuring agents, clay minerals in various forms, and Micro and macronutrients of organic origin.
  • the plastic microfibers are preferably made of UV-stable polyester and link the organic matter, thereby forming a rot-free reinforcement and linkage of the vegetation layer.
  • the dried seaweed forms a cohesive colloidal mass due to the connection with the water added when it emerges from the spray nozzle, which creates a point connection with the capillaries of the vegetation layer.
  • the Opalinus expanded clay balls on the one hand form structure donors and on the other hand increase the water storage capacity.
  • the seed is sprayed on in the same operation, which leads to an organic seed layer 2 after a short time.
  • depressions 8 with a depth of, for example, 1/2 meter in the surface 10 of the embankment substrate 5
  • these are filled with a material 7 before application of the vegetation layer, which is also reinforced with fibers, but consists of less expensive material.
  • the reinforced layer 7 can be mixed with sand, for example.
  • a static network or base fabric may be required if the surface is very unstable. As a rule, however, such a prior mechanical stabilization of the slope is not necessary. It has even been shown that the vegetation layer according to the invention can also be used to green embankments that are comparatively strongly susceptible to slipping without any further safety measures.
