Definitions

  • the invention relates to a device for protecting the central root area of trees, consisting of a molded body made of concrete surrounding the root area and provided with openings and having an upper cover with an opening for the passage of the tree trunk.
  • DE-A-29 20 873 describes a device for planting trees and the like, in particular in traffic areas, which consists of a trough which can be lowered into the ground, on the edge of which a multi-part plate projecting above the trough and having a recess for the tree trunk is put on.
  • the known device has the disadvantage that the trough does not have an upper cover directly connected to it, but that the multi-part plate is retrofitted, i. H. after planting the tree on which the trough must be placed. Apart from the fact that there are always several parts to be kept in stock, the known device has disadvantages with regard to its static strength. In addition, it is not possible to adjust the diameter of the upper opening provided in the cover according to the wax state of the tree with simple means.
  • DE-U-86 08 185 describes a precast concrete shaft for planting pits of trees, large shrubs and the like, which consists in the shaft being composed of vertical wall elements which have a horizontally angled pedestal at their lower edge. No integrated top cover is provided for this precast concrete shaft either.
  • the shaft itself also does not consist of one piece, so that disadvantages may also arise in the static case of the previously known shaft. Furthermore, it is impossible to carry out a subsequent transplanting of trees with this prefabricated shaft without the shaft being destroyed.
  • the EU 87 05 377 relates only to a support device for tree grate segments, which consists in that a Support ring extends approximately to the inner edge of the tree grate segments and that at least along the outer edge of the tree grate segments support beams are arranged on the support ring to support the tree grate segments.
  • This is not a molded body which has openings and surrounds the central root region of the tree.
  • the present invention has for its object to provide a device of the type mentioned that does not affect the living area of the tree even during and after the attachment of the square or road system and that remains as a unit in the root area and possibly together with the tree can be moved.
  • a device of the type mentioned which is characterized in that the shaped body has a trapezoidal longitudinal section with oblique side walls that form a larger opening at the bottom and is made in one piece including reinforcement and upper cover, and that in the opening in the upper cover a plurality of semicircular, mating disc rings are inserted or removed to change the diameter.
  • the payload and traffic loads are not discharged into the ground above, but through the walls of the molded body below the root system. Furthermore, the living area of the young tree in the humus bed and the subsequent wing substructure are clearly separated from each other. It has an installation-related shaking and stabilizing the area around the tree has no influence on its growth area. Road construction and planting measures can thus be carried out at completely different times and completely undisturbed.
  • the young tree with its root ball can easily be planted through the existing, large installation opening at the top of the shaped body.
  • the space available is sufficient for a protected and protected root development during the first years.
  • the roots will gradually penetrate through the openings provided in the side walls, which can be circular, for example, and thus allow the tree to continue growing.
  • Another important advantage is that the loads are transmitted into the ground when the device is driven below the root system, with the trapezoidal longitudinal section of the concrete body, which is produced in one pour, achieving particularly good stability.
  • the rectangular or square, trapezoidal, hollow molded body on the lower edges of the sides have circular segment-shaped recesses.
  • the corners of the shaped body forming the lower edges can form supports for foundations, soil or underlying slabs, which likewise results in an improvement in stability with regard to the load transfer into the soil without impairing the root system.
  • Fig. 1 is a perspective view of an embodiment of the device according to the invention.
  • Fig. 2 shows a section through a device inserted into the ground with a tree according to the invention.
  • the device for protecting the central root area of trees consists of a trapezoidal, hollow molded body made of concrete material which is open on the underside.
  • the molded body has four side walls 1 and an upper cover 2, in which there is a circular opening 3.
  • the diameter of the opening 3 can be enlarged or reduced by a plurality of disc rings 4 which fit into one another and which, for example, are semicircular and are provided with corresponding annular shoulders 5.
  • a plurality of disc rings 4 which fit into one another and which, for example, are semicircular and are provided with corresponding annular shoulders 5.
  • Recesses 7 in the form of circular sections are provided on the lower edges of the side walls 1.
  • the corners 8 of the shaped body forming the lower edges form supports for plates 9 inserted into the ground, each under the corners 8 in the ground are arranged.
  • the young tree initially designated 10, with the ball of earth 11 is introduced from above through the opening 3 into the shaped body and transplanted with it in the ground.
  • so many semicircular washers 4 are placed on the top that protection of the trunk and the root ball located underneath is ensured.
  • the roots pass through the openings 6 and anchor themselves in the ground.
  • the respective inner ring disks 4 are removed accordingly, so that an adaptation to the development of the tree trunk can be made.
  • the pressure loads emanating from the adjacent surface area are discharged into the ground on the outer walls of the sides 1 via upright corners, in-situ concrete foundations or the plates 9, so that the central root area is protected from such loads.
  • Fig. 3 the possibility of stacking the device according to the invention in the form of a trapezoidal structure is shown.
