Abstract

Process for establishing a sound-proofing wall (4) along a traffic road or the like according to which branches are planted close to one another in the soil and are made to grow, in such a way that they can grow into and against one another so as to form a closed wall. Panels (5) being positioned between two rows of branches to obtain an almost closed wall immediately after the planting of the branches, said branches previously being connected to one another by means of threads or ropes to form a sort of weave.

Description

  • The invention relates to a process for establishing a sound-proofing wall along a traffic road or the like wherein woody plants, either already having roots or not, are planted close to one another in the soil and are made to grow in such a way that at least partly they grow into and against one another so as to form a substantially closed wall.
  • Such a process is known from the document "POLYTECHNISCH TIJDSCHRIFT - GELUID EN TRILLING", vol. 35, nr. 4, August 1980, pages 101-108.
  • A disadvantage of this known process is, that no closed wall is obtained immediately after the planting of the plants. In view of the irregular shapes of the plants there will be free spaces between them which will influence the effect of the wall negatively.
  • Now the invention aims to remove this drawback by providing a process for establishing a sound-proofing wall, which process is easy to carry out and provides a wall with a natural aspect and good sound-proofing properties, and the wall also occupies little space. The process according to the invention is characterized in that two rows of plants spaced at a small distance from one another are planted in the soil, that panels are provided between said two rows of plants are are connected to these to obtain a closed wall immediately after the planting of the plants, a number of plants situated on opposite sides of the panels being connected with one another by means which extend through holes in the panels.
  • In this way a totally closed wall is obtained directly after the planting of the plants and besides' this the strength of the wall will be improved by the means connecting plants at either side of the panels.
  • In order to enable the planting of the plants close to one another in a simple way, so that also after the planting the plants will be in one single, essentially vertical, plane, it may be provided, according to a further embodiment of the invention, that a number of plants, before being planted into the soil, are connected with one another by means of threads, ropes or the like, which are provided at a right angle to the longitudinal direction of the plants and at a distance from one another, and which are wound in such a way around the consecutive plants that a sort of weave is obtained.
  • The manufacture of this woven product can take place, if desired, in a factory hall, so that the work in the open air and along the traffic road takes as little time as possible. In this way, optimal use can also be made of the time that the weather conditions are favourable for planting the plants.
  • Because of the transportation of the woven product and the handling thereof at the planting of the plants, the woven product will be manufactured in certain lengths, so that it can be wound e.g. into a roll which is easy to handle.
  • In order to prevent untavourable retlections of sound between two walls set up at both sides of a road, it may be desirable to let the plants, seen in a plane at a right angle to the longitudinal axis of the traffic road, form an angle with the vertical plane, in such a way that the tops of the plants are directed away from the longitudinal axis of the road. The reflection of the sound by the walls then does not take place approximately parallel to the plane of the road, but more obliquely upwards, so to the area above the road.
  • As observed above, it is necessary to provide means to obtain a closed wall immediately after the planting of the plants as well, as, because of the irregular shapes of the plants, there are already free spaces between the plants, which would influence the effect of the wall negatively.
  • According to an embodiment of the invention, the means for obtaining a closed wall consist of panels of metal, synthetic materials or a similar material.
  • So the plants actually form the foundation for the panels concerned.
  • As material for the panels, use will be made of course of a non-oxidizing material, and especially a corrugated panel of glass-fibre-reinforced polyester is thought of.
  • The means for connecting with one another the plants situated at both sides of the panel may consist in particular of a strip which lies against the outside of two juxtaposed plants and which is connected, by means of a threaded rod passing between the plants and through the panel, with a similar strip, which lies against two plants at the other side of the panel.
  • By providing such a connection between the two rows of plants, also the bending resistance thereof will be increased, so that the wall will resist better to wind loads.
  • For obtaining the required plants, use can be made of woody fast-growing plants, such as willow, oak, black alder, maple, hornbeam, hawthorn and the like.
  • It is well-known that especially willows grow very fast, so that especially this material qualifies. In the choice of the material, however, attention will have to be paid also to the local soil condition and vegetation and to other factors such as the sensitivity of the material used to illnesses and plagues. Because thereof, it may also be desirable to use several types of material next to one another or to use a mixed composition of plants.
  • Furthermore it will be obvious that, although in the above there has been question in particular of a sound-proofing wall, such a wall can also be used for establishing partitions which do not have a negative effect on the environment.
  • The invention will be described in the following by means of an example of an embodiment shown in the drawing, in which:
    • figure 1 shows a lateral view, partly at an enlarged scale, of a number of plants which have been united into a strip of weave,
    • figure 2 shows a section of a part of a sound-proofing wall obtained by using two strips of weave of figure 1, immediately after the erection of the wall,
    • figure 3 shows a section similar to the one of figure 2, but after a period of one to two years after the erection of the wall,
    • figure 4 shows a section similar to those of figures 2 and 3, but after a number of years have passed since the erection of the wall, and
    • figure 5 shows a vertical section of a traffic road with a sound-proofing wall according to figures 2-4 provided along that road.
    • Figure 1 shows the weave 3 which can be planted into the ground and which consists of plants 1 and connecting threads 2. Possibly the one end of the plants may already have roots, so that the plants will grow faster after the planting.
    • Figure 2 shows, at a larger scale than figure 1, a cross section over a part of a sound-proofing wall 4, which consists of two weaves 3 and a corrugated panel 5 therebetween, which corrugated panel may consist in particular of glass-fibre-reinforced polyester.
  • For connecting with one another the weave strips 3 situated at both sides of the corrugated panel 5, use can be made of two strips 6, which are connected with one another by means of a threaded rod 7, on which nuts 8 are screwed, as is shown schematically in figure 2.
  • It may be observed that with the strip of weave in figure 1 the connecting threads 2 are always wound entirely around a plant and are therefore situated alternately in the one outside surface and the other outside surface, whereas figure 2 shows the possibility that in fact there is a binding thread in both surfaces, in which case the two binding threads are wound around one another between two plants.
  • Figure 3 shows the wall as shown in figure 2, but about one or two years after the plants 1 were planted, this in dependence on the material of the plants. The plants 1 will then have come to lie against one another over almost their entire length, so that the corrugated panel 5 will then have lost its function for the greater part.
  • Figure 4 shows the wall after more years have passed and the plants 1 have grown into one another, so that a very firm wall has been obtained. Parts of the corrugated panel 5 may now have been enclosed entirely by the plants 1, so that a firm support of the corrugated board 5 has been obtained.
  • In the situation as shown in figures 3 and 4, the connecting threads 2 can either be enclosed entirely by the plants grown into one another, or such a material can be used which will disappear by natural influences after some time.
  • Figure 5 shows the erection of a sound-proofing wall 4 along the one side of a traffic road. As appears in particular from this figure, the corrugated panel 5 will extend itself to a point slightly under the surface when the plants are planted, whereas furthermore the plants are planted somewhat obliquely in order to prevent the reflection of the noise over the road itself. In general a rather sharp limitation of the twigs at the upper side of the wall will be necessary, as otherwise too much dispersion of the noise might occur, which means that the noise might be reflected downwards again, which in general is undesirable.
  • In general it will be desirable that the sound-proofing wall is interrupted locally, such as for making passages for pedestrians and cyclists. In that case a second wall will be erected parallel to the first wall, immediately behind the passage, in such a way that the noise passing through the passage is caught by the second wall. The second wall, of course, only has to have a very limited length. To begin with, the ends of the walls can be supported by thicker plants or posts, whereas of course also supports can be used and this not only at the ends of the wall, but also at other places for supporting the plants as long as these are not yet rooted in the soil sufficiently.
  • All these possibilities, however, will be obvious to the expert and therefore need no further explanation.
