Definitions

  • the present invention relates to a method for attaching a vegetation subfloor serving for vegetation to an embankment and / or to a wall according to the preamble of claim 1, to an implementation of the method and to an embankment and / or wall with vegetation soil applied by the method .
  • a first procedure relates to not very steep unpaved slopes. After a slope correction, for example when creating a new road, there is no longer any humus on the corrected or newly created embankment that would allow plants to grow.
  • the application of humus is not easy due to the risk of flooding in heavy rainfall. It is known, therefore, before applying the humus So-called three-dimensional grids are attached to the ground with pegs. Three-dimensional grids are flat structures with elements protruding from the base. Such grids are laid covering the embankment and give the subsequently applied humus layer a hold against washing out or slipping. This method is suitable for slopes with a slope angle of up to approximately 50 °.
  • the steep support wall 1 the surface of which the vegetation subfloor is inclined by at least 10 ° with respect to the vertical, consists of reinforced shotcrete and is provided with ground nails 9 anchored in the ground 2.
  • the grids are fastened to the supporting wall 1 with fastening elements 4.
  • the latter are, for example, nails, screws or pins.
  • they serve to provide the freshly applied vegetation sub-soil 5 with a first initial hold. Furthermore, they reliably prevent washing out and / or slipping of the vegetation underbody 5 in adverse weather conditions.
  • the vegetation sub-soil 5, the composition of which is described in detail further below, must offer the seed 6 applied to its surface the possibility of good rooting after germination. As in known and proven methods, the seed 6 is mixed with an adhesive and then the vegetation underbody 5 is sprayed with this pretreated seed.
  • the freshly applied seed is covered, for example, with straw mats 7 for protection until germination.
  • the vegetation underbody 5 is applied with a thin layer of at most 25 cm, but preferably only about 8-15 cm.
  • the layer thickness of the vegetation subsoil essentially corresponds to the dimension of the parts of the three-dimensional grid protruding from the wall. So that the thinly applied vegetation underbody not drying out disproportionately quickly, recesses 8 are provided in retaining walls 1 or walls, which allow the natural moisture of the soil 2 to access the vegetation underbody.
  • water collecting devices 10 are arranged in these recesses, which store water in particular after a precipitation and gradually release it to the roots of the plants. Worn-out car tires, for example, can serve as the water collecting device.
  • the vegetation underbody is prepared as a mixture of a substrate, a soil stabilizer and water.
  • Humus and / or compost are essentially suitable as substrates.
  • a preferred substrate is manufactured by the Ricoter company in Aarberg. It contains approx. 35% by volume of dried beetroot, approx. 25% by volume of compost from tree bark and organic waste from agriculture and the food industry, approx. 20% by volume of rice fur and approx. 20% by volume of white peat. The percentages represent a recommended mixing ratio.
  • the individual components can be varied within wide limits between 0 and 70%.
  • the well-known product Hüls Terravest 801 from Hydrosaat in Bern has proven to be suitable as a soil stabilizer.
  • the soil stabilizer is admixed with 0.1 to 20, preferably 8, percent by volume.
  • the above-mentioned soil stabilizer is a liquid plastic that, after application of the vegetation subsoil, depending on the temperature, under the influence of atmospheric oxygen cures for a few hours and connects the substrate in itself and with the three-dimensional grid. No skin forms on the surface of the vegetation subsoil, so that the soil's absorbency for rainwater is fully preserved. Therefore germination and plant growth are not affected.
  • the soil stabilizer gives the substrate the necessary resistance to withstand strong winds and downpours. It has proven to be advantageous to add 1 to 20 percent by volume of water to the substrate, in particular when applying the vegetation underbody with a spraying device.
  • a vegetation sub-floor can also be retrofitted in a relatively simple manner to a concrete wall that has existed for years.
  • the method according to the invention for attaching a vegetation sub-floor is not only distinguished by significant price advantages, but also makes a contribution to environmental protection.
  • the vegetation sub-floor can also be attached to long-standing retaining walls or walls without any significant additional space requirement.
