EP1749943A2 - Vaulted module - Google Patents

Abstract

The arc module (1) has an arc-shaped wall (2) that has longitudinal sides folded to form supports (4), and a subgrade level (7) formed on one edge. Stiffener ribs (5) with crimping openings (6) are formed on the surface of the arc module. The edges of the support are supported by stiffener fingers (11) against the wall.

Description

The invention relates to a vault module for producing a seepage tunnel, which is formed from an arcuate wall, wherein the wall along its longitudinal edges each having a support edge for the flat support of the vault module on a planum, has in the direction of its longitudinal extension successively arranged stiffening ribs in the form of periodic surveys and is broken by a variety of seepage openings.

Such a vault module is already out of the WO 03/100180 A2 known. In this document, a vault module is described, which can be assembled by means of various connection modules in rows to form a seepage tunnel, the tunnel can also run around curves and corners.

From the European Patent EP 0 705 946 B1 Furthermore, a so-called seeping room is known, which is also a chamber with perforated side walls, which form an arcuate cross-section. It is known from this document that such seepage chambers On the one hand have to have the required stability due to the acting environmental forces and therefore often have ribs reinforced side walls and also are usually open on the bottom side to be stackable. The European patent, the object is to provide a seepage chamber with increased sidewall seepage capacity and at the same time not lose the required sidewall stability. This succeeds in such a relevant trained seepage obviously by the fact that not only the side walls, but also their stiffening ribs are perforated.

In the prior art design, however, the very pronounced external ribbing due to the desired stability of the seepage chamber appears to affect the stackability of the seepage modules, or at least substantially increase the footprint of the stacked seepage modules.

In general, such vault modules, and in particular the seepage tunnels that can be produced therefrom, serve for drainage of land. The rainwater accumulating on roofs, balconies or even concrete or paved areas is usually supplied to the drain by means of the roof slope or a slope provided in the area to be drained, which in turn supplies the water to the sewer.

In the past, this has increasingly led to the rivers feeding a great deal of water, because the water that would normally seep into the land was fed to the rivers via canals. Downstream collects in this way much more water, the more Areas of nature are taken as seepage areas by sealing.

Conversely, it is essential to keep traffic areas clear of water, as aquaplaning vehicles can cause vehicle drivers to lose control of their vehicle and cause an accident. It is also disadvantageous to let the water deposited on a roof flow as a surge through the garden, as this would soften the ground and in the worst case would destroy the planting.

The above-mentioned infiltration tunnels now provide a solution for creating both the space required for infiltration and the traffic areas such as roads and parking lots from the water. In an excavated pit, a planum, ie a flat surface which is formed of gravel, is prepared first. On top of this, the seepage tunnels made up of vault modules are placed and, if necessary, connected to the planum. The vaults created in this way are covered with soil and can then be entered, transplanted and even driven on.

A supply line for filling the tunnel, for example, by a connection to the gutter or a drain. Water collected in the tunnel will now be slowly and continuously released into the soil and will no longer be sent to the sewers and thus to the rivers. The prerequisite for this, however, is that the soil is also able to be infiltrated.

The US 2003/0161685 A1 also describes such a vault module, in particular a method for their preparation. In this case, a wire frame is used according to this method, which works out the vault shape of a block of rigid, air-permeable material with a rotating movement.

Also known is from the EP 0705946 to produce such vault modules whose walls are provided with perforated ribs through which the leachate can penetrate the vault wall.

However, all these vault modules have the disadvantage in common that only a very limited amount of water can seep through the tunnel resulting from such modules. For an increase in the capacity of the known seepage tunnels, it is always necessary to provide a larger area, ie a larger planum. In addition, it brings problems with, for example, produce higher or wider vaults, as they no longer muster enough strength to support the overlying soil.

Against this background, the present invention seeks to provide a vault module, with a much greater efficiency in terms of space requirements for the infiltration of a certain amount of water and at the same time a high degree of stability is ensured.

The solution of this problem is achieved by means of the vault module according to the features of the main claim. Further advantageous embodiments are described in the subclaims.

The vault module according to the invention has along its longitudinal edges in each case a support edge on which the vault module can rest on the subgrade. The problem here is the pressure exerted from above through the soil on the open vault module, which would push the vault modules into the planum. The larger the support margins are pronounced, the more pressure can be absorbed thereby. The size of the support edges can not be arbitrarily increased for cost and practical reasons, since the edges tend to break in such a configuration. A corresponding contribution to the strength of the support edges make additional stiffening fingers, which support the support edges in their right-angled arrangement with respect to the wall against them.

Advantageously, the bottom of an initially open vault module is formed by a bottom surface. Due to the resulting smooth floor surface, it is possible to drive the seepage tunnel with a camera and, if necessary, find faulty spots, blockages or other things of interest in the seepage tunnel. The bottom surface is connectable to the support edges, preferably by means of a tapping of the bottom surface with the support edges, so that the flanks of the vault module are additionally held against the pressure of the soil.

The maintenance aspect is further supported by the fact that in the middle of the bottom surface of a channel runs, in which any deposits flow. Such a gutter is Easy to clean with appropriate cleaning equipment.

As far as the vault module is placed directly on the subgrade, it is advantageous to additionally connect the relevant module to the ground by means of a ground anchor driven by one of the support edges. As a result, it is avoided that shifts occur when filling the seepage tunnel. After the seepage tunnels are mostly filled in with construction machinery, a large amount of material may press asymmetrically on one side of the modules and displace the pressure due to displacement. With the aid of the ground anchor, the modules fixed in this way are each held in at least one place.

An effective way to increase the capacity of the seepage tunnel is in the pyramidal arrangement of additional modules. Above two lower seepage tunnels, for example, another seepage tunnel is created in the middle of the convex arches, from which the water contained in them seeps down into the two underlying tunnels. As a result, the storage capacity of the tunnels increases considerably and the rainwater can be continuously discharged over a longer period of time.

Advantageously, the vault module according to the invention is such that it can be combined with a second vault module as needed to form a double volume seepage tunnel. For such an increase in the capacity of the seepage tunnel, an open vault module is first placed on the planum so that the Arch vault to planum points. On the upstanding supporting edges now a second open vault module is placed with its support edges so that a tube, thus a closed vault module is formed. It is also possible to arrange the vault modules offset in the longitudinal direction in order to achieve a greater degree of rigidity. Then, however, the offset must be equalized at both ends of the seepage tunnel. The interconnected support edges additionally avoid pushing apart the Gewölbewände.

Since the vault module first brought into position on the subgrade is not necessarily straight due to the roundness of its wall, which can lead to problems in assembling the seepage tunnels, anti-tipper means are provided on the convex vault side. These are essentially formed of a strut, which forms a straight resting edge, so that the module rests on this edge and is no longer movable on the arc rounding.

As an alternative to pure infiltration, it may be advantageous if the lower vault module has no seepage openings. Such a module can be used as a cistern so that water can be stored for removal.

Generally, no bottom surface is used in a two-shell arrangement. Rather, a bottom plate is inserted into the lower module, which as well as the bottom plate is camera-driven. In addition, this floor plate can if necessary by means of margins to a gutter be reformed, which in turn can be easily cleaned with cleaning equipment.

In an advantageous embodiment, a cistern or a seepage tunnel can also be constructed in such a way that alternating vault modules with individually arranged open vault modules are combined to form an overall arrangement.

In this case, a plurality of analogously structured layers can be combined with each other in this arrangement, wherein for reasons of stability, a staggered position to position arrangement is selected.

The strength against the soil pressing from above can be improved as an alternative or in addition to a bottom surface, that means for cross-bracing between two opposite support edges are introduced so that even with greater pressure, the support edges can not be pushed apart due to the tension of the means for cross-bracing , The transverse reinforcement can be realized both as a material strip connected to the support edges, and also as a chain or band.

Advantageously, this means for cross-bracing is connected by means of a tapping with the support edges. This type of connection is on the one hand very durable, as by the use of solid, possibly metal, pin a long life is achieved, on the other hand, it is easy to open, should take place once a conversion or about an extension of a seepage tunnel.

It has proven to be useful to provide a tongue and groove connection for connecting rigid components. In particular, this is also advantageous in the vault module according to the invention, since this is a very simple connection. The vaults, which are firmly embedded in the soil in the course of their construction, do not require a particularly complex, but a simple, strong connection, since the seepage tunnel should not fill with soil over time.

It has proven to be advantageous if the tongue and groove joints used for connection with other modules are sealed watertight using sealants. This is of course especially recommended in connection with such modules, which are set up as a cistern.

The bumps distributed periodically over the vaulted ridges of the module, from which the stiffening ribs are formed, are also internally supported by means of stiffening means. Since these directly oppose the pressure by their highlighted position, so a yielding of the wall is avoided.

For the manufacturer and the buyer, it is of great interest to have the lowest possible expenses for warehousing and transport. Therefore, it has proved to be advantageous if the vault modules are stackable. As far as possible, an overhead module rests with its inner wall surface on the module below. Where this is not possible, it rests on the stiffeners of the periodic elevations, which are perpendicular stand on the lower surface and thus can absorb the greatest pressure.

Advantageously, vault modules, for example terminal modules, can be closed with an end wall, which is preferably also equipped with a tongue and groove connection.

In the front wall recesses, for example, provided for cleaning or camera handling of the seepage tunnel, which are preferably initially closed. Depending on requirements and purpose, the required recesses can be opened only when installing the end wall. Likewise, the recesses can be used as inlet or as overflow of the modules. The modules are usually fed by water infiltrating from the surface of the earth and by water introduced from gutters or traffic areas, for example. While the former penetrates by itself through the vault walls, the latter must be introduced into the seepage tunnel by means of pipes and hoses.

For a simplified transport, it makes sense if the housing module engages over an area which corresponds approximately to the transport surface of a Euro pallet. Alternatively, it is advisable to choose the surface so that an integer multiple of the surface corresponds to the surface of the pallet. This ensures efficient transport of the vault modules.

In another alternative arrangement also two vault modules can be laid one above the other stacked. This can be on site in a structurally simplest way double-walled seepage tunnel with correspondingly increased load capacity can be created.

The invention described above is explained in more detail below in an exemplary embodiment with reference to a schematic drawing.

FIG. 1 shows a vault module 1 for forming a seepage tunnel, which is formed from an arcuate wall 2. The vault module 1 is reinforced by means of stiffening ribs 5, which better support the pressure of the surrounding soil. The wall 2 is penetrated by a plurality of seepage openings 6 through which the rainwater to be seeped through the wall 2 can pass. A seepage tunnel is created by juxtaposing vault modules 1, which are connected together in series by means of a tongue and groove system 10.

To build a seepage tunnel, the area to be dewatered is first dug out and a subsurface 17 is created. This is fixed with gravel and carries the seepage tunnel. The vault modules 1 are placed on the planum 17 and optionally with anchored to this. For this purpose, the vault wall along its longitudinal edges supporting edges 4, which are supported with the vault module 1 with its surface. Then the soil is filled up and compacted on the seepage tunnel. The pressure of the soil from above is additionally supported by means of the support edges 4.

By sprinkling the surface, the rainwater to be seeped passes either via the seepage openings 6 or through supply lines into the seepage tunnel. There it can be stored first and then gradually released to the surrounding soil.

Figure 2 shows how a vault module 1 can be greatly increased by assigning a second, along its longitudinal axis rotated by 180 °, vault module. The doubled capacity of the seepage tunnel is suitable for larger areas or larger amounts of water. The stability of the housing modules is ensured by means of anti-tilt device 7, which hold the modules 1,1 'in an upright position. The strength of the arrangement is additionally increased by means of transverse stiffening 8 in that the pressure of the soil from above, which would normally lead to a squeezing apart of the vault flanks is collected. The means for transverse stiffening 8, in this case a metal strip, which is connected by means of a tapping with the support edges 4, prevents the pressing apart of the vault flanks and thus ensures a solid arch shape.

FIG. 3 shows a sectional view of a single arch module 1, which is under attack by a bottom surface 14. The bottom surface 14 is camera accessible, so that the state the seepage tunnel is conveniently visible from outside the tunnel buried in the ground. Along the central axis of the bottom surface 14, a groove 15 is arranged so that flushed into the tunnel leaves, sand or the like when emptying the tunnel is preferably flushed into the channel 15. The channel 15 itself can be cleaned from the outside by means of cleaning devices which are pushed through the tunnel. To improve the stability of the arch, the bottom surface is connected on both sides with the support edges of the vault module by means of a tap 9. The tapping 9 in contrast to about a screw has the advantage that it can be produced without tools.

FIG. 4 shows a vault module 1 to which an end wall 16 is assigned. The end wall 16 limits the tunnel in its longitudinal extent so that on the one hand no soil can penetrate, but on the other hand, an orderly introduction of a camera or cleaning agents is possible. For this purpose, the front wall is associated with a maintenance opening 19, which is initially closed, but easy to open by means of a perforation. At this maintenance opening 19 pipes or hoses for feeding a camera or cleaning agents can be connected. In addition, the end wall has inlet openings 20, through which, also by means of pipes or hoses, water collected on the site to be drained water is fed into the tunnel. Such inlet openings 20 are likewise arranged in each case on the vaulted back of the seepage tunnel between two stiffening ribs 5.

FIG. 5 shows an arrangement of a plurality of seepage tunnels 3 into a pyramidal shape. Several side by side Seepage tunnels 3 are supplemented by a series of seepage tunnels arranged laterally offset. Thus, a simple and effective increase in capacity can also be achieved. By means of taps 9 the overhead vault modules are firmly connected to the modules below.

FIG. 6 shows a Euro pallet 18, on which a multiplicity of vault modules 1, 1 'are mounted. The fact that the modules are stackable, they can be stored in a small space. At the same time, the vault modules 1, 1 'have the same base area as the Euro pallet 18, so that the most efficient use of space is guaranteed.

Figure 7 shows a sectional view through a vault module 1, which is connected by means of ground anchors 13 with a flat 17. The Planum 17 is prepared prior to the assembly of the seepage tunnels and consists of a surface as flat as possible of gravel. The vault modules placed thereon, which are assembled by means of their tongue and groove joints to form a seepage tunnel, can then be fixed using the ground anchors 13 in the planum 17, so that they can not move during the cover with soil.

FIG. 8 shows an open vault module 1, to which a second, vault module 1 ', which is rotated by 180 ° along its longitudinal axis, is assigned. The two open vault modules 1, 1 'are accordingly to a closed, here largely oval vault module. In this case, only the upper open vault module 1 has seepage openings 6 through which water enters the seepage tunnel can penetrate. The stability is enhanced by means of transverse stiffening 8 so that the seepage tunnel is not forced apart due to the weight of the surrounding soil or the water accumulated in the tunnel. In this compilation, the tunnel can be used as a cistern, which can also be filled or emptied by a submersible pump as needed.

FIG. 9 shows a double-walled drainage tunnel which consists of at least two open vault modules 1, 1 '. In this case, the open arch modules 1, 1 'stacked one inside the other, that the stiffening means of the stiffening ribs 12 of the above vault module 1 is largely perpendicular to the outside of the wall 2 of the underlying vault module 1' touches. By this double-walled design, a considerably higher stability is achieved, whereby a greater load on the lying above the seepage tunnel ground surface is possible.

Figures 10 and 11 show a special possible arrangement of the open vault modules 1, seen in cross section in alternation with closed vault modules 1 and 1 'laid. To increase the absorption capacity and the swallowing capacity of the overall arrangement, a plurality of correspondingly constructed layers can also be arranged one above the other, but each offset by a vault module.
