Definitions

  • the invention relates to a trench body for the production of rainwater storage ridges, the trench body having at least one cavity, the trench body having at least three grid-like, partially water-permeable walls, one wall being designed as a ceiling and two walls as side walls of the trench body, and two being opposite one another Sides of the drain body are open.
  • Rigid bodies of the type mentioned at the outset are mainly used in the area of roof areas and traffic areas, such as streets, parking lots and sealed plots, where normal seepage of the precipitation and thawing water is not sufficient to return the water to the water cycle.
  • An infiltrated storage space is created by means of a drain body and a rainwater storage drain, which can be used to hold back the resulting water and thus, for example, throttled it into the sewage system.
  • the trenches can also be used to store rainwater, for example for irrigation, fire-fighting water, cooling water, process water or the like.
  • a known trench has at least one trench body which is arranged in the ground.
  • a water supply leads to the rainwater storage drainage so that the drainage can absorb surface water supplied.
  • a trench body is characterized by the fact that the water is stored within a cavity can and the stored water can be released to the soil surrounding the drain body, or can be discharged into the sewage system.
  • Rigid bodies can, for example, consist of several elements such as the base part, support columns, ceiling part and side walls and can be installed on site. This gives an increased assembly time on site.
  • a problem with the use of trenches is that fine sediments can be introduced into the trench due to the infiltration or supplied rainwater and this can lead to silting up of the trench. Flushing the trench, for example by means of a high-pressure flushing process, can, owing to the grid-like walls, result in the fine sediments being distributed throughout the entire trench system, so that cleaning of the trench is hardly possible.
  • the invention is based on the object of proposing a drainage body of the type mentioned at the outset, in which sediment distribution is considerably reduced and simple cleaning and time-saving installation on site is made possible.
  • the trench body has at least one cavity, the trench body having at least three grid-like, partially water-permeable walls, one wall being designed as a ceiling and two walls as side walls of the drain body, and with two mutually opposite sides of the Trench body are open, it is essential to the invention that the drain body is in one piece is configured that the drain body has a channel for collecting sediment and for flushing and that the bottom of the channel is designed as a molded, closed, water-impermeable floor pan or that the bottom of the channel is designed as a molded, grid-like, partially water-permeable wall.
  • a drain body for a rainwater storage drain has at least one cavity.
  • the drain body has at least three grid-like, partially water-permeable walls.
  • the drain body can have two mutually opposite side walls, which are designed like a grid.
  • the drain body can have a ceiling that adjoins the grid-like side walls.
  • the ceiling can also have a grid-like structure, so that rainwater can penetrate through the side walls and the ceiling into the cavity which is formed between the side walls and the ceiling area.
  • Two opposite sides of the drain body are open, so that a channel for collecting sediment and for flushing is formed through the open sides and the cavity between the ceiling and the opposite, lattice-like side walls.
  • the drainage body, in particular the canal is closed at the bottom by a canal floor.
  • the floor can be designed as a closed, water-impermeable molded-on floor pan.
  • a trough-shaped channel floor enables fine sediments to be collected. Fine sediments can in particular be fine particles, on the particle surfaces of which, for the most part, the dissolved pollutants can also adhere, which are carried along with the supplied rainwater.
  • a closed floor pan particularly precludes sediments from spreading completely over the entire drainage floor of a rainwater storage drainage canal made up of several drainage bodies and increasingly reducing the infiltration capacity through colmation. Due to the channel floor designed as a waterproof floor pan, this can Sediment can thus be collected and, for example, be flushed out of the rainwater storage canal using a pressure flushing process. This enables easy cleaning of the drainage system.
  • the channel floor can alternatively be formed by a lattice-like, partially water-permeable wall.
  • the drainage floor represents a seepage-effective area.
  • the construction of a lattice-like channel floor enables a modular construction of a rainwater storage drain.
  • trench bodies with a water-impermeable channel bottom and with a water-permeable channel bottom can be arranged one above the other, so that the sediments from a plurality of trench bodies arranged one above the other are collected in a lower trench body with a trough-like channel bottom.
  • drain bodies with closed and lattice-like which have lattice openings, i.e. open, rinsing channel floors, very time-saving installation on site and precise adaptation to local conditions is made possible.
  • the channel has side walls, the side walls of the channel being designed as the side walls of the drain body.
  • the side walls of the sediment and rinsing channel are formed by the side walls of the drain body. This enables a particularly optimized construction of the trench body with a large cross-section for pipe connections as well as cost-effective production.
  • the drain body is produced in one piece in an injection molding process.
  • the formed drain body can be produced inexpensively in one piece in an injection molding process, wherein various injection molding tools can be selected for embodiments with a water-impermeable bottom and water-permeable bottom.
  • the side walls adjoining the bottom of the channel are formed at least in sections like a grid, and the side walls formed like a grid each have grid areas with different grid structures.
  • the side walls adjoining the channel floor are formed at least in sections like a grid.
  • the side walls have areas with different lattice structures.
  • a dividing line that is to say a transition between the different lattice structure areas, can be formed between the different lattice structure areas, wherein the dividing line can be arranged parallel to the channel floor.
  • a side wall can thus initially have a first lattice structure region with a first lattice structure, which is adjoined by a second lattice structure region with a second lattice structure.
  • the various lattice structures prevent the sediment accumulated on a closed trench floor from being distributed to neighboring trench bodies, for example when flushing a trench.
  • the lattice structure area of a side wall adjoining the bottom of the channel has a lattice structure with smaller openings than a lattice structure area adjoining the ceiling area.
  • the lattice structure area adjacent to the channel floor has smaller lattice openings than the lattice structure area adjacent to the ceiling area.
  • the side walls therefore initially have smaller mesh openings, to which an area with larger mesh openings adjoins.
  • the lattice area adjacent to the channel floor can have, among other things, smaller, slit-like lattice openings, while the lattice area adjacent to the ceiling can, for example, have larger lattice openings.
  • the smaller openings in the lower lattice area can in particular prevent it from rinsing a channel with a closed bottom, for example by means of a High-pressure flushing device, in addition, sediments whirled up by the flushing water can penetrate into adjacent drain bodies.
  • the sediment-laden rinsing water can be retained through the small, in particular slit-like grating openings and can be flushed out of the trench into a rinsing shaft via the closed channel bottom.
  • At least one side wall has at least one flushing deflection profile on its side facing the cavity for deflecting a flushing water flow.
  • Flush deflecting profiles are arranged on at least one side wall, preferably on the two side walls of the drain body, on the sides of the side walls facing the cavity.
  • the rinsing deflection profiles can be profile sections which protrude from the inside of a side wall into the cavity.
  • the rinsing deflection profiles are arranged on the side walls approximately parallel to the upper edge of the closed floor pan.
  • the flushing deflection profiles additionally prevent the flushing water loaded with sediment from penetrating into the adjacent trench body when flushing a drainage channel using a flushing device. Thanks to the flush deflection profile, the grille areas of the side walls can be shielded from the swirled flushing water, so that a distribution of the flushing water into neighboring drain bodies is minimized.
  • At least one rinsing deflection profile is arranged between the lattice structure regions and the rinsing deflection profile is arranged parallel to the plane spanned by the ceiling.
  • Flush deflecting profiles can be arranged on the sides of the side walls facing the cavity, which are arranged in particular parallel to the upper edge of the channel of the drain body and thus parallel to a plane spanned by the ceiling, in particular by the upper edges of the drain body.
  • a Flush deflection profile between the two grid areas of a side wall. Additional rinse deflection profiles can be arranged adjacent to the two grid areas.
  • a first rinsing deflection profile can be arranged between the channel floor and the first grille area, a second rinsing deflection profile between the first grille area and the second grille area and a third rinsing deflection profile between the second grille area and the ceiling of the drain body.
  • the first grating area adjacent to the floor has smaller, slit-like grating openings than the second grating area adjacent to the ceiling, which is separated from the first grating area by a flushing profile.
  • the smaller openings in the grating area adjacent to the floor prevent the rinsing water loaded with sediment from passing into an adjacent drainage body.
  • the larger openings in the grating area adjacent to the ceiling enable a complete distribution of a water volume to be absorbed by the trench over all the trench bodies.
  • the drain body has at least one ventilation channel.
  • the drain body has at least one, preferably two ventilation channels.
  • the ventilation channels are arranged in the upper area, in the ceiling of the drain body.
  • the ventilation channels can in this case be open at the top, so that a channel for ventilation can be formed between a ceiling of a first drain body and the bottom of a second drain body arranged above the first drain body.
  • the ventilation channels can be used for ventilation in the longitudinal and transverse directions via a system of trench bodies.
  • a network of ventilation channels can be formed, so that the air volume to be displaced can be removed from a trench with many trench bodies. This enables complete filling, i.e. a full utilization of the available space by absorbing rainwater.
  • At least one ventilation duct is arranged in the ceiling of the drain body.
  • Stiffening elements in particular profile areas, can be formed in the ceiling, in particular in the transition between the side walls and the ceiling.
  • the venting channels can be arranged in these profile areas, which can serve, for example, to stiffen the drain body.
  • a ventilation duct is preferably formed in each profile area between the ceiling and the two side walls. Due to the formation of the ventilation channels in the profile areas, there is no special space requirement for the ventilation channels, so that the spatial volume of the cavity of the drain body is not restricted by the arrangement of the ventilation channels.
  • the drain body has at least one emptying channel.
  • the drain body can have drainage channels. If several drainage trays are arranged side by side and one behind the other, the drainage channels can enable longitudinal and lateral drainage across the entire drainage system.

  • a transition area between the bottom of the channel and the adjacent side walls is designed as a profile area and the profile area forms at least one emptying channel.
  • profile areas can be formed, for example to stiffen the drain body.
  • drainage channels can be designed to discharge the rainwater that accumulates in the cavity of the drain body, without restricting the volume of the cavity of the drain body.
  • a complete emptying of a trench to the bottom of the trench is thus possible, for example with a retention trench for throttled discharge into the sewage system or into a receiving water.
  • the drainage channels in particular when a plurality of trench bodies are arranged to form a trench system, enable transverse and longitudinal drainage of the trench system.
  • the drain body has connecting elements for connection to at least one further drain body.

  • the channel 5 is formed by a cavity in the drain body 1 and is bounded at the bottom by a channel floor 6, which in this embodiment is formed by a closed, water-impermeable trough.
  • the closed channel floor 6 enables sediments to be collected, which are introduced into the drain body 1 by inflowing rainwater.
  • the accumulation of the sediments on the trough-like channel floor 6 prevents the sediments from being distributed into the entire drainage system consisting of a plurality of drainage bodies 1, and removal of the sediments by rinsing is made possible.

  • the grille area 7, which adjoins the channel floor 6, has a plurality of and smaller grille openings than the grille area 8, which adjoins the ceiling area 4, in order to minimize the penetration of flushing water laden with sediment into adjoining drain bodies.
  • the drainage body 1 has drainage channels 9, 10 for draining the cavity.
  • the drainage channels 9, 10 are arranged in the profile areas 11, 12, which are formed in the transition area between the side walls 2, 3 and the channel floor 6.
