Definitions

  • the invention relates to an infiltration system, namely a trench to be laid underground, with one or more hollow bodies which are intended to keep a volume free in the ground into which a fluid to be infiltrated, preferably rainwater, can be introduced for intermediate storage and infiltration, with a Channel or one or more flushing hollow bodies that form a channel, and with a settling device for settling suspended matter contained in the fluid.
  • the invention can also be used in a storage system, in which case the volume is not covered with permeable material, but with dense film.
  • trenches that contain distribution pipes and are filled either with gravel or with infiltration devices are often used to temporarily store and infiltrate rainwater.
  • Modern storage and infiltration systems now often contain modular hollow plastic bodies, which together form the static support of the container (corset) and, depending on the application, are covered with nonwovens (infiltration system) or foil (storage system). Due to their design, these hollow bodies contain a variety of different struts that are used to absorb or dissipate force. They are often designed as boxes that can be placed or fastened together and on top of each other, which together form the supply channels and the required cavity for the water. They are usually so stable that the area above them can be used as a roadway or parking lot.
  • the partially filtered or unfiltered rainwater drains reach the actual container via a connecting line (pipe socket or internal shaft). There, the incoming rainwater can be distributed almost freely in the container in one, two or three dimensions. However, this also applies to the registered dirt cargo.
  • An integrated infiltration device in which a settling device for settling the suspended solids is provided in a channel.
  • the settling device there consists of a fluid-impermeable trough or channel on the bottom of the channel and openings (holes, slots) on the sides. This causes suspended solids to settle to the bottom and can later be removed by rinsing.
  • the disadvantage of this is that the existing dirt load is constantly kept in motion by inflowing rainwater, is broken down due to constant friction processes and is then ultimately - for example in heavy rain - discharged through the openings into the actual trench. This leads to colmation of the nonwovens at the transition between the storage elements and the soil, which limits the ability of rainwater to seep away.
  • This device forms the preamble of claim 1.
  • the DE 202005 010090 U1 describes a trench element for the infiltration of surface water with at least one of the liquid-permeable side walls of the trench Hollow chamber for temporarily absorbing the seeped surface water, this hollow chamber being stiffened with column elements that are at least essentially vertically arranged when installed as intended and the trench element having a continuous inspection channel.
  • the EP 2 385 178 A2 describes an arrangement that has spatial areas between support pillars, with the support pillars being arranged next to each other in a predetermined direction.
  • the WO 2005/040501 A1 relates to a drainage container with at least one water-permeable wall and a pipe projecting into the container, the pipe wall of which has a lower shell section and an upper section which is provided with through openings.
  • the EP 2 687 642 A1 describes an irrigation and/or drainage assembly comprising a box body having a base wall provided with perforations and body side walls provided with perforations that extend vertically and are integrally connected to the base wall.
  • the US 4,145,157 A relates to a modular drainage panel section and a method of manufacturing a drainage panel section with upper and lower housings connected together to form each drainage panel section.
  • the object of the invention is to improve such an integrated infiltration or storage device in such a way that the dirt load is kept more safely away from the actual cavity and is easier to remove.
  • a fluid-permeable film a cloth, a fabric, a membrane or a fleece is used, which extends over long distances within the volume and which preferably runs under and next to a channel. Fluid permeability does not have to be present everywhere; it can be sufficient if it exists at least in sections.
  • the channel can be formed in one piece as a type of tube or from several parts.
  • the channel is preferably composed of a plurality of hollow flushing bodies which are aligned uniformly so that together they form the channel which extends over a longer distance in the volume. This channel can then be used for inspection or to flush and remove the deposits.
  • the film can be made up of individual pieces or larger areas.
  • the hollow flushing bodies are covered with foil/membrane at the bottom and on two vertical sides. This can preferably be pre-assembled or done during installation, so that the hollow flushing bodies forming the settling device are simply covered with film/membrane.
  • the individual film sections do not necessarily have to be connected to one another in a sealing manner, since the pieces of film are held in the right place by the neighboring hollow bodies. The pieces of film thus form a channel that is permeable to the fluid, usually rainwater.
  • the films are impermeable to the solid suspended matter, sediments, abrasion particles or dirt and act like a filter that retains the solids.
  • channel elements are simply covered with foil/fleece on the two vertical walls and at the bottom (U-shape), settling spaces remain between the channel opening and the underside of the elements as well as on the sides of the elements thanks to the many struts, in which, thanks to the lower flow speed Particles can settle and sediment.
  • the hollow flushing bodies that form the channel and are covered are connected directly or indirectly to the connection of the inlet line. This can also be done via an internal shaft or via a section of pipe inside the container.
  • One channel or several channels can be provided, which then run perpendicular to one another or parallel to one another.
  • the length of the channels can be freely selected. If they do not end at the end of the volume at the soil fleece, it must be ensured that a (solid or liquid-permeable) barrier is also provided at the end of the channel for the still contaminated rainwater.
  • not only a single strand of hollow bodies is covered with film/membrane, but also the hollow bodies arranged vertically above the strand. Then their sides also form a kind of higher filter space, so that when there is more rain, significantly more water can be filtered than in the "flatter" version.
  • the film/membrane can also only be arranged over partial areas (horizontal/vertical). This can vary depending on the project and is usually intended to handle peak hydraulic flow situations.
  • the inlet channels can also be equipped with other installation elements that optimize flow and sedimentation. These can be, for example, flow separators, baffles, diving or mud walls. These installations serve for hydraulic and qualitative optimization in the channels.
  • a grid-like element is used which is located within a channel. This grid runs along the channel and divides it into an upper flow space and a lower settling space. Suspended particles fall through the grid and collect at the bottom. This collecting effect is improved by the fact that structures are arranged on the bottom of the canal that form obstacles and inhibit the flow speed. These can be grooves, elevations, depressions or similar roughness between which the solids can settle. These special characteristics of the flow bottom can form a kind of mud chambers that can later be flushed out.
  • Fig. 1 shows schematically an infiltration system 1 according to the prior art (Fig. 2 the DE10 2005 006 202 A1 ), in which rainwater from a house roof is introduced into the cavity 2 to seep away after a cleaning stage.
  • a settling device 3 which here consists of a channel made of fluid-impermeable material that is open at the top but closed at the back in the direction of flow and has a row of openings 4a at a certain height and a second row of openings 4b above it.
  • Rainwater remains in the gutter and only flows out through the rows of openings 4a and 4b. This ensures that dirt settles on the bottom of the gutter and does not flow into the actual volume 2.
  • Fig. 2 shows a top view of an infiltration system according to the invention 1.
  • Section AA is shown above. It can be seen that the volume 2 was created underground and is now filled with hollow bodies 5.
  • These can be, for example, ENREGIS ® /X boxes, which are so stable that they keep volume 2 free and allow rainwater to flow through. The boxes are covered with water-permeable fleece towards the bottom, on the outside and at the top - i.e. where the volume comes into contact with the ground - which allows the water to seep away slowly.
  • a fluid-permeable fleece is now provided as the settling device 3, which is located below the hollow flushing bodies 6 and to the side of the hollow flushing bodies 6. It encases, so to speak, the channel 7 formed by the row of hollow flushing bodies 6 in a U-shape. Rainwater introduced passes through the channel 7 and - since the fleece is permeable to fluid - can flow into and fill all the hollow bodies 5 underneath and next to it. Since the fleece retains solids, suspended matter, dirt and abrasion remain reliably within the fleece 3 and are deposited there on the sole and in the lower area.
  • the fleece is arranged outside the structural elements of the hollow flushing bodies 6, the solids collect in the undercuts, in holes and on struts of the hollow flushing bodies 6, i.e. in the settling spaces 8, which are in Fig. 3 are easier to recognize and can sediment there. These solids can be removed again by regular flushing of channel 7.
  • Fig. 3 shows the section BB of the infiltration system 1 at the top Fig. 2 and below a detailed enlargement.
  • the settling device 3 i.e. the fleece, is drawn in exaggerated thickness as a “U”. It includes the channel 7, which is formed by the row of hollow flushing bodies 6.
  • the settling spaces 8 are located within the fleece 3. Possible inlets 9 of sizes DN 110, DN 160, DN 200 and DN 315 can be seen within the channel 7.
  • Fig. 4 shows a further embodiment of an infiltration system 1 according to the invention, in which not only the hollow flushing bodies 6, which form a channel, but also the hollow bodies 5, which are located in a row above the channel, and the hollow bodies 5, which are one row further up are surrounded by the fleece that acts as a filter.
  • the fleece is again U-shaped, but has significantly longer legs. In the case shown, the fleece extends over two, even three layers of hollow bodies 5 and 6 to the upper edge of the volume 2 and abuts directly on the telescope cover 10. Can be seen are again the channels 7 and, in an enlarged detail, the fleece acting as a settling device 3 - strongly drawn in a U-shape - and the settling spaces 8.
  • Fig. 5 finally shows a detail of yet another variant of an infiltration system, in which no fluid-permeable fleece, but a fluid-permeable grid 11 is provided in an inlet channel 7.
  • the separation of floating particles and liquid occurs here in that the liquid flows through the channel 7 (essentially a pipe) and floating particles or dirt particles fall down through the grid 11 and onto the bottom of the channel 7 on or between specially applied structures settle and get stuck.
  • the grid 11 is preferably arranged in the lower region of the channel 7 and extends essentially over the entire length of the channel 7.
  • the channel 7 can, as previously described, be assembled from several hollow flushing bodies. However, it can also be inserted into the volume in one piece or in prefabricated lengths. It can be arranged in front of the actual trench, but also within it.
