Definitions

  • a floor covering arrangement according to the preamble of claim 1 which aims to reduce soil compaction.
  • This document suggests covering the tree slice with eight rectangular, hollow concrete elements that are open at the bottom. The top of the elements is formed by a reinforced grid connecting the side walls. Below this grid, the soil should not be compacted and the grid should provide sufficient water and air. It ever happened However, it has been shown that the stress on the elements concentrated on the lower edge of the side walls of the elements leads, just below this edge, to the same soil compaction as grass pavers laid on the ground. Soil compaction is only superficial, but not reduced in the root area. In addition, this known floor covering arrangement also has all the other disadvantages of grass pavers mentioned above.
  • the invention has for its object to eliminate the disadvantages mentioned. This object is achieved by the characterizing features of claim 1.
  • a floor covering arrangement for sidewalks is known. It consists of prefabricated concrete support elements with a U-shaped cross section. At a distance of the length of the elements, a number of elements stacked in pairs on top of each other are laid as foundations. Further elements are placed on these foundation elements with their longitudinal ends laterally next to each other and abutting one another in the sidewalk axis. This allows you to create a sidewalk with prefabricated elements.
  • this arrangement is not intended for covering tree trunks from street trees. It has not established itself for the production of sidewalks. Normal road surfaces are preferred here.
  • the arrangement shown is square in plan and comprises four foundation beams 2 made of reinforced concrete arranged radially around a tree trunk 1 along the square diagonals.
  • the inner end faces 3 of the opposite foundation beams 2 are spaced apart.
  • the foundation beams 2 are supported on two piles 7 each.
  • the piles 7 are produced, for example, by drilling holes in the ground and filling them with concrete.
  • Two adjacent carrier elements 4, 5, 6 abut one another at their ends with their leg ends.
  • the innermost support element 4 is narrower than the other two and has a rectangular cross section, while the other two support elements 5, 6 have a U-shaped cross section.
  • the carrier elements 4, 5, 6 are laid on a smooth line to compensate for any inaccuracies in height. Between the smooth line and the elements 4, 5, 6 there is still a separating film which prevents the elements from connecting with the smooth line. This way, they can be easily removed later for any work. When the tree grows and the trunk 1 becomes thicker, the inner support elements 4 can be removed.
