Definitions

  • the invention relates to a trench unit according to claim 1, which is formed substantially as a hollow body and a base wall and a plurality of connecting walls which protrude from the base wall, wherein at least a part of these walls is permeable to liquid, and wherein these walls at least one Limit fluid intake volume.
  • EP-A-0 943 737 has proposed a trench assembly composed of a plurality of trench units.
  • This trench assembly forms an underground water basin, which is connected upstream with at least one gully, so that it the rainwater collected on the sealed surface through the at least one gully and optionally on it subsequent feed system can be supplied.
  • the bottom surface of the trench assembly is liquid-permeable, so that the rainwater supplied to it can seep into the underlying soil.
  • the trench assembly can be connected to the sewage system in order to be able to prevent backflow to the surface when the accumulated rainwater quantity exceeds the absorption capacity of the soil and the trench arrangement.
  • a soil treatment device is disclosed in US-A-3220194.
  • the known device is used for aerating, humidifying and fertilizing a soil for the treatment of soil and consists of a substantially solid-walled box, which has in its walls openings through which the surrounding soil air, fertilizers, water or the like are supplied.
  • the device has a box passing through, substantially full-walled tube, in the wall a number of holes are provided for the passage of the liquids. Except for the interior of the tube, the entire interior of the box is filled with a spongy material.
  • EP-A-0787865 discloses a trench unit for a drainage system which consists essentially of a parallelepiped cavity in which a plurality of columns perpendicular to the bottom surface of the trench unit are provided. For the exchange of water between adjacent trench units, these have openings in respective opposite side walls, which in each case oppose an opening of an adjacent trench unit.
  • DE-A-19705824 also describes a drainage system consisting of coupled trench units filled with a pore-forming material. Also, these trench units have for feeding and draining to percolating water in their side walls Openings on.
  • a trench unit according to the preamble of claim 1 is known.
  • the walls of the trench unit enclose two cavities for receiving wastewater and have openings through which the water can reach the surrounding soil.
  • the water supply of the known trench unit via a continuous channel whose lower bottom wall arranged at a greater distance, extending perpendicular to the channel grooves, which introduce the guided water in the channel through openings in the channel wall in the cavities of the trench unit.
  • a disadvantage of the known trench arrangement is the fact that the rainwater introduced into it carries all kinds of debris, in particular dirt, dust, earth particles and leaves, carelessly discarded waste, for example cigarette butts, and the like. Also, the presence of screen baskets in the gullies as well as the provision of gullies in the feed system can not prevent a significant portion of this garbage from getting into and contaminating the trench assembly, especially the seepage openings at the bottom of the trench assembly. Since there is no possibility for cleaning in the known trench arrangement, the known trench arrangement is gradually rendered inoperative.
  • the infiltration system Juncus Duobox REWATEC This is formed by a package of perforated plastic corrugated sheets, which is penetrated approximately at half the height of a perforated plastic pipe. Due to its design as a corrugated iron core, this infiltration system has a high stability in terms of passing on or driving on. However, this design hampers the even distribution of the supplied water over the entire seepage soil area. At least that can be added Do not spread rainwater in the silt box as quickly as needed during a downpour. In addition, the perforations in the drainage pipe and the corrugated sheets increase relatively quickly if no suitable filter is connected upstream of the infiltration system. Although a cleaning lance can basically be introduced into the drainage pipe. However, the water ejected from this cleaning lance can at best clean the perforations of the drainage pipe. On a cleaning of the entire Sickerbox, but especially the infiltration effective bottom surface, is due to the corrugated iron execution in any case.
  • an inspection device for example a camera dolly, and / or a cleaning device, for example a high-pressure lance discharging water or a rinsing vehicle, can be introduced into the trench unit from time to time by the inspection channel provided according to the invention.
  • the open at both longitudinal ends training the inspection channel ensures that when putting together a plurality of such rigging units to a trench assembly, the cleaning device can move from rigging unit to rigging unit, so as to clean the entire trench assembly.
  • the inspection channel extends over a large part of the height of the trench unit.
  • the inspection channel may extend over substantially the entire height of the trench unit.
  • the inspection channel is bounded laterally by at least two connecting walls, it can be ensured that the inspection device moves in a targeted manner along a predetermined path in the trench arrangement.
  • the two connecting walls take up relatively little volume, so that the liquid receiving volume of the trench unit according to the invention essentially corresponds to that of a single-chamber trench unit.
  • the connecting walls delimiting the inspection channel practically do not hinder the uniform distribution of the liquid over the entire base area of the hollow body forming the trench unit, since they are at least partially formed as a lattice structure.
  • they increase the stability of the trench unit so that it is easily accessible and passable.
  • a base surface of the inspection channel can be arranged adjacently to an envelope of the base wall.
  • the base surface of the inspection channel may have a predetermined distance from the envelope, within which, for example, stabilizing or stiffening ribs may be provided.
  • the base surface may be formed by a portion of the step-shaped base wall.
  • the base surface of the inspection channel is formed substantially over the entire surface, i. if necessary, it is perforated by a small proportion of the total area of this base area, preferably slot-shaped openings.
  • the preferably slot-shaped openings ensure that the water stored in the trench unit can also seep through the base surface of the inspection channel. If the longitudinal direction of these slots is substantially orthogonal to the longitudinal extent of the inspection channel, they may assist the traction of the wheel-based inspection device as it moves along the inspection channel.
  • the inspection channel may preferably be arranged approximately in the middle of the transverse extension of the trench unit.
  • At least one of the free ends of the inspection channel may be formed for connection to a pipeline or to a pipeline adapter.
  • the pipe to be connected to the inspection channel may also be only a short piece of pipe for connecting the trench monolith to a shaft running vertically in the ground.
  • This shaft can be, for example, an inspection shaft through which inspection and cleaning device can be introduced into the inspection channel.
  • the shaft can also be provided a sinking volume, in which at least a portion of the rainwater entrained debris can settle before the rainwater in the Trench arrangement is initiated. In this sinking volume but can also be flushed out by the cleaning device from the bottom of the trench assembly messed up and debris. The sink volume of the inspection well can then be cleaned in a conventional manner.
  • the shaft can also be an overflow shaft, which in turn is in turn connected to the sewer system. Therefore, the uppermost layer of trench units is preferably connected to this overflow shaft so that liquid from the trench assembly only flows into the overflow shaft when the storage volume of the trench assembly is exhausted.
  • At least one of the free ends of the inspection channel may further comprise an insertion slope facilitating the passage of examination and / or cleaning equipment, for example wheel-supported equipment, from trench unit to trench unit.
  • this instruction slope allows a higher tolerance when laying the trench units.
  • the trench unit comprises two base walls which run essentially parallel to one another.
  • one of the base walls form a bottom wall of the trench unit, while the respective other base wall forms the top wall thereof.
