Abstract

The storage body (10) has a fluid storage derived partly on the horizontal fluid level (12) with the storage body. An inclined to wavy surface of the storage body is provided with a sealing. A surface sealing is anchored for protection against lifting force in the underground.

Description

The The invention relates to a storage body or a formed thereof Volume expansion of conventional Storage body for storage, or temporary retention of liquids, especially for Rain drainage systems, the own memory space, or an additional usable memory space conventional Storage body too below inclined surfaces by adjusting the storage body to the surface course enable should.

Out The prior art are from the last few years various possibilities become known liquids and rainwater below green areas or buildings, or in whole or in part within surface coverings of roads and / or courts stowing in this way storage bodies of gravel, gravel, lava, or the like, or modular storage blocks made of latticed plastic boxes or Other industrially produced cavity-forming packing, too create.

So is from the European patent EP 0 938 615 a multi-layered bottom surface for the disposal of, inter alia, rainwater known, wherein the built-in a Bodenabdichtungswanne hochtragfä higen and pore-rich gravel is supplied via at least one resting on the drainage drainage water and discharged again.

Out the European Application 01913561.5 a seepage system is known that largely in the superstructure of traffic areas to integrate and that over Drainage pipes initiated Water in particular over the large sole of the infiltration system seeps into this underlying soil.

Out the European Patent Application 00904802.6 a water pipe is known in which the formed from gravel storage layer without further channel components directly serves as a water conductor.

U. a. from the company Franconian Tubes is one of many cuboid plastic lattice boxes too forming Füllkörperrigole (Rigo-Fill), in which the over Pipe introduced water and some of the water underlying soil layers, or to another part of the faces the trench is seeped.

From u. a. The company Euroecuperator are semicircular plastic bowls or clay for gravel overburdening combined formation of once-volume increased Rigolenkörpern known.

From Mall-Beton are cisterns made of concrete with one in the upper area as infiltration system perforated concrete wall known in the lower cistern area service and / or extinguishing water stockpiled by continuous storage.

Alles these many different water storage and / or drainage systems have in common that the water stored in it only horizontally Stowing up to a maximum filling level is. Is the storage body under a sloping or downhill course is the lateral and / or longitudinal profile difference between the horizontal stowage in the conventional storage body and the transverse and / or longitudinally inclined surface not usable as storage space.

This usually requires a deeper installation of the conventional storage body, what with considerable additional Earth excavation and its disposal as well as deeper lying pipelines can go along.

Of the Invention is the object of a private storage body form or the aforementioned from the prior art liquid storage to extend to the memory according to the invention, that also in the area between the known horizontal liquid level and one across and / or along inclined, or wavy up to arbitrarily shaped surface of the inclined to wavy congestion of liquid at least partially can be realized.

Around the task of the invention a partial to largely non-horizontal Storage volume, or additional Storage volume to meet are the following types of construction, or additions particularly suitable.

Around liquid inclined to be able to collapse the surface of the storage body in these additional To perform area in sealed form.

was it at one exclusively horizontal storage does not require sealing the memory on the surface, so this is on inclined surfaces from the previous horizontal level to the upper additional inclined to wavy level of unavoidable, if one leaks a liquid expertly from the store wants to counteract.

If this additional sealing edge were simply extended further upwards, this would generally have the disadvantage that the material, which is located inside the storage body below the upper level of the suppression, does not belong to the storage body lien also be jammed during the storage process, what for z. B. surface structures of traffic areas is not allowed.

Consists this restriction not a higher one drawn edge seal without surface sealing sufficient be.

To the Protection of adjacent components is accordingly preferable a parallel to the inclined to wavy surface extending upper seal on, the exit into the adjacent, in particular resting Soil layers at the same time prevented by the sealing effect of the to allow inclined to wavy congestion below the surface first.

disadvantage This construction is next to the additional resting on the memory Sealing requirements of the profile depth between Einstauoberkante and lower edge of the additional Gradual levels increasing hydrostatic pressure with increasing congestion in the additional Storage space, which in case of non-observance in the planning phase to a later Damage by lifting the materials resting on the seal through the hydrostatic buoyancy forces can lead.

Therefore is such a designed additional Storage space above the upper seal to secure against these forces.

This can in particular in two ways such. B. by back anchoring the sealing layer in the underlying components and / or Soil layers or in a simpler form by appropriate Support weights, or combinations thereof.

at a back anchoring the hydrostatic pressure forces are compensated by the buoyancy forces over her Dead weight insufficient counteracting surface seal over ground anchor or comparable fastening materials in the underlying substrate anchored. Does the surface seal in such cases an elastic material is also a surface stabilization of the seal if necessary advantageous, since these otherwise between the Anchor points at elevated Bulge out would.

Also For this reason, a compensation of the buoyancy forces on counterweights, or Auflager, usually the better way, sometimes because in the Verkehrsflächenbau fast big weights at low coverages due to the heavy materials from z. Gravel, gravel, sand, paving stones, Concrete and / or bitumen coverings can be achieved.

Already From these examples above can also be the diverse design of the surface sealing detect.

These can depending on the application either only as a web of films, Tile / film combinations, geotextile sealing membranes (eg bentonite membranes) Foam sheets and / or self-sealing sealing materials of Road construction such as bitumen or concrete coverings but also from plate-shaped seals, z. B. be formed from sheets. In addition, all sealing variants can be combined with each other.

But no matter how the buoyancy forces is compensated, is dependent from the maximum possible hydrostatic pressure an increasing effort to its compensation operate, with the safety factors reducing efficiency to take into account are.

Pass the anchorages and / or counterweights of the surface covering alone no longer out of the buoyancy forces it is still to be resisted possible the deepest areas of the extra Storage space further into the superstructure (eg gravel and / or frost protection layers protrude into it to gain more counterweight, up to the sole of the inventive or conventional storage body is reached in total. This point with its overlapping counterweights is due to its support forces after deducting the security surcharges usually the maximum possible Specify the level of accumulation.

No later than must start from the maximum level on continuation of the storage body be decided whether from here only horizontal stowage in this one storage body done or an additional storage area same height next to and / or above next to and / or above previously described storage area is to be provided, so as a series arrangement and / or cascade of at least two or even more equal in height and / or offset in height storage areas to build.

are the storage body offset each other is usually a lateral seal inevitable to an uncontrolled leak of liquid to prevent.

The Shape of the storage volume according to the invention is dependent from the selected storage medium or its combination (bulk goods and / or filler) free selectable and is usually subject only to the aforementioned implementation recommendations to be able to work permanently safely.

The filling and emptying the storage space according to the invention is done either over the underlying memory space with - or, if one not available, about the well-known Be and drainage system of the prior art, in particular from drainable materials such. B. Drainage pipes and / or Drainage areas and / or Formed filler can be.

is the storage body Below most airtight surface coverings is also a ventilation with provided.

As already be taken from the full texts to the prior art can the memory of the invention also with lateral and / or underlying water permeable and / or impermeable Layers of films, fleece / film combinations, geotextile sealing membranes (eg Bentonitbahnen) foam tracks and / or self-sealing Traffic road construction sealing materials such as bitumen or concrete coverings but also from plate-shaped Seals, z. B. from sheets or dense pending soil layers to be self-educated. In addition, all sealing variants are mutually exclusive combined.

In The drawings are several embodiments of the invention shown. they show

1 shows a trench in cross-section

2 shows a water tank in longitudinal section

3 shows another water tank in longitudinal section

4 shows a water tank as a cascade in longitudinal section

In 1 is a largely in the road superstructure ( 15 . 16 integrated trench infiltration, whose inflow into the water via a trench ( 20 ) installed drainage pipe ( 19 ) he follows. The rising in it and then in the water reservoir ( 18 ) and the planum ( 32 ) seeping rainwater could according to the prior art so far only up to the horizontal liquid level ( 12 ).

The enlargement of the retention space according to the invention ( 35 ) to the storage body according to the invention ( 10 ) takes place via the horizontal liquid level ( 12 ) to just below the paving bedding ( 14 ).

So that the water does not flow laterally into the superstructure ( 15 - 16 ) can emerge in addition to the higher edge seal ( 31 ) a surface seal ( 11 ) essential.

In order to ensure the ventilation under the surface seal is a ventilation pipe ( 27 ) provided that is connected to a shaft, not shown, with perforated cover.

Since the additional storage body according to the invention ( 38 ) only very little height difference between horizontal liquid level ( 12 ) and surface sealing ( 11 ) allows a buoyancy protection by the resting paving bedding ( 14 ) and paving stones ( 13 ) in total.

In 2 is a in road superstructure ( 15 . 16 ) and grown soil ( 30 ) integrated water storage ( 18 ) made of ballast as an alternative to a stagnant channel formed from pipes for rainwater caching.

The water retention takes place via a lateral inflow pipe ( 23 ) and a drainage pipe ( 19 ) into the very cavernous gravel of the water reservoir ( 18 ). As already in 1 here too, the water can be represented above the horizontal liquid level ( 12 ) to below the paving bedding ( 14 ), because the net weight of paving bedding ( 14 ) and paving stones ( 13 ) provide sufficient counterweight to the buoyancy forces.

Again, just below the seal a ventilation pipe ( 27 ) provided that over the adjacent shaft ( 26 ) ensures the required ventilation. The rainwater drain itself also takes place via the drainage pipe ( 19 ) and a drain line ( 24 ) to the shaft ( 26 ) throttled in normal operation via an outflow throttle ( 29 ), or in the case of heavy rain events via an overflow device ( 28 ), that also has the task of preventing a hydrostatic overpressure in the storage body according to the invention, in a drain line ( 25 ).

The in 3 illustrated water storage is off 2 very similar. Only in the surface design of the storage body ( 10 ) there are differences.

Thus, only a portion of the surface is below the maximum level, the Rieselschutzvlies ( 33 ) and does not have to be sealed because of its horizontal position.

Only the subjacent area ( 18 . 35 ) of the storage body ( 10 ) is to be sealed, whereby again on the surface seal ( 11 ) paving ( 13 . 14 ) enough Ge against the maximum buoyancy forces.

On a final and final ventilation can be omitted here, since the large with Rieselschutzvlies ( 33 ) occupied surface of the storage body ( 35 ) sufficient ventilation through the superstructure ( 15 . 16 ) and paving ( 13 . 14 ).

In 4 , is one too 3 shown comparable water storage in which the water storage of several largely identical successively arranged cascade stages ( 10 . 34 ) is formed.

Due to the large height difference between horizontal liquid level ( 12 ) and the Rieselschutzvlies ( 33 ) surface is the low point of the surface seal ( 11 ) so far below the traffic area ( 17 ) that their paving ( 13 . 14 ) and superstructure ( 15 . 16 ) generated counterweight can superimpose the buoyancy forces occurring with its own weight.

The deviating from the upper of storage body ( 10 ) formed first cascade stage channel components for supply and discharge and ventilation are in the following cascade stage ( 34 ) not shown.
