Description

The present invention relates to a channel for the removal of surface waters with at least one lower part, which has at least one drainage channel, and at least one upper part arranged in an operating position above the lower part.

In general usage, flumes are natural or artificial, open-top containments of effluent small bodies of water. In this case, it is artificially produced, upwardly open drainage channel body with which surfaces such as parking lots, depots, roads, pedestrian walkways, pedestrian areas and the like can be drained after rainfall. The channels can be installed in asphalt, concrete, masonry, paved surfaces and other surface coverings or substrates. The upper edge of the built-in flume is usually flush with the surrounding surface to be drained. The lower part of the channel has the gutter, in which the surface water is collected and transported away. In the prior art, the upper part, which often carries or has a grid or the like, lies directly on the lower part. Practice shows that known in the prior art channels are damaged or destroyed by heavy traffic relatively quickly. By such loads, it comes in the prior art in particular to cracks in the gutter of the channel.

The object of the invention is to improve a channel of the type mentioned above so that it has a higher durability even under heavy loads.

This is achieved in a flume of the above-mentioned type according to the invention by the upper part and the lower part are separate components of the channel, which are supported or supported separately in the operating position on a substrate.

In other words, the invention thus provides that no or at least no significant direct load-transmitting connection between the upper part and the lower part of the channel is present. This prevents that when driving over the channel by heavy vehicles applied to the upper part of the load is discharged directly to the lower part of the channel. As a result, the lower part is relieved and it no longer comes to the breaking phenomena occurring in the prior art in the gutter. According to the invention, it is thus provided that upper part and lower part are supported in a load-transmitting manner, individually and separately from one another, in the substrate surrounding the installed channel. This makes it possible for the upper part and the lower part to be able to perform a relative movement with respect to one another during the load by means of heavy traffic and the like, without any impairment or destruction of the channel. It is preferably provided that the upper part and the lower part in the operating position exclusively indirectly, e.g. over the underground, are interconnected.

Particularly preferred embodiments of the invention provide that the upper part in the operating position has downwardly facing upper side walls and the gutter in the operating position upwardly facing gutter side walls and the upper part side walls and the gutter side walls in the operating position overlap each other. By this overlap on the one hand, a telescopic relative movement between the upper part and lower part with appropriate load is possible. On the other hand, the overlap can also ensure that all the surface water flowing into the top of the channel is also directed into the gutter. In this context, it is particularly favorable if the upper side walls facing downwardly protrude in an interior of the gutter arranged between the gutter side walls.

It is also favorable in this context, when the upper side walls project freely downwards in the operating position and / or project freely up the gutter side walls in the operating position.

In addition to the flume per se, the invention also relates to an arrangement with a substrate and a built according to the invention in the subsurface channel, wherein it is provided that the upper part has Obererteildruckplatten with which the upper part is supported on a support layer of the substrate, and the lower part has contact surfaces , with which the lower part stands on a support of the ground, and the support layer on another material, preferably on backfill material, supports the subsurface.

As a result, with a corresponding load, the upper part can move particularly well relative to the lower part a bit, without the load being transferred directly from the upper part to the lower part.

Preferred embodiments of such an arrangement provide that the support is made of concrete or of compacted, preferably originally present, material of the substrate. It can also be provided that a cover layer, preferably in the form of fine asphalt, is applied to the base layer and to the upper part pressure plates of the upper part.

Based on Fig. 1 First, the problems occurring in the prior art will be explained by way of example. Shown is in a vertical section known in the prior art channel 1 ', which is installed in the substrate 16 and on a support 23, which may be, for example, a concrete layer, rests. The upper part 4 'of this channel 1' according to the prior art is directly and thus load-transmitting on the lower part 2 'on. The lower part 2 'is formed in the prior art essentially by the gutter 3', which is often designed as a concrete body. The cover layer 30, which may be, for example, an asphalt surface, is flush with the upper edge of the upper part 4 'of this channel 1' and lies in a manner known per se on the support layer 29. The surface water accumulating on the surface of the cover layer 30 passes over corresponding, not shown here and in the following figures slope through the grid 10 'of the upper part 4 in the gutter 3' and is transported therein, for example, in a corresponding shaft, channel or the like. Now drives a heavy vehicle or the like on the channel 1 'and its upper part 4' and its grid 10 ', the loads shown by the arrows 24 are transmitted from the upper part 4' directly to the lower part 2 '. In addition, lead directly to the chute 1 'in the ground 28 launched loads 24 also to side loads 25, which press laterally against the gutter 3'. In total, it comes through the loads 24 and the side loads 25 in the prior art often to cracking and destruction in the gutter 3 'and in the lower part 2', which are illustrated here in the form of cracks 26 and 27.

In the Fig. 2 to 6 Now, a first embodiment of the invention is shown. Fig. 2 shows a frontal view of the channel 1 and its end face 17. The support 29 and cover layers 30, as they are commonly encountered in normal road construction, are shown only for completeness with and are not attributable to the channel 1. The support layer 29 and the cover layer 30 are thus not part of the channel. In Fig. 3 is the upper part 4 of the channel 1 from Fig. 2 detached from the in Fig. 4 shown lower part 2 of the channel. Fig. 5 shows a view obliquely from above on the channel 1, Fig. 6 a perspective view obliquely from below, wherein one of the side walls 12 is removed. In this embodiment, it is provided that the upper part 4 and the lower part 2 are separate components of the channel 1, which are supported or supported separately in the operating position on the ground 16. The upper part 4 and the lower part 2 are not directly but exclusively on the ground 16, in which the channel 1 is installed, connected to each other. Thus, it is possible, for example, as shown here, that the upper part 4 by means of its shell printing plates 7 on the support layer 29, as is well known in the asphalting of squares and streets, supported while the lower part 2 with its contact surfaces 15 on a suitably suitable Support 23 stands and is supported by this. The support layer 29 and the cover layer 30 are part of the substrate 16 and store on the other material or the other layers of the substrate 16, here the backfill material 35. The support 23 may be a separately built-in support layer such as concrete. However, the support 23 may also be a corresponding, optionally compacted material of the originally present substrate 16. Ultimately, the support 23 is in any case also part of the underground 16.

Fig. 2 shows the operating position. In this figure, it is easy to see that the upper part 4 is not stored directly on the lower part 2. Rather, there is a possibility that, with a corresponding load 24, the upper part 4 relative to Lower part 2 moves a piece, without the load is transmitted directly from the upper part 4 on the lower part 2. As a result, the in Fig. 1 illustrated occurring in the prior art cracks 26 and 27 in the gutter 3 of the lower part 2 avoided.

This telescopic possibility of movement between the upper part 4 and lower part 2 of the channel 1 can be achieved in preferred embodiments as shown here by the upper part 4 in the operating position downwardly facing upper side walls 5 and the gutter 3 in the operating position upwardly facing gutter side walls 6 and the Top side walls 5 and the gutter side walls 6 overlap each other in the operating position.

This also ensures that the surface water passing through the upper part 4 is completely introduced into the gutter 3 of the lower part 2. For this purpose, it is particularly favorable, as also realized in the exemplary embodiments shown here, when the upper part side walls 5 are located in the region between the gutter side walls 6. The shell side walls 5, as shown here, cantilever freely in the operating position, as well as the gutter side walls 6 can freely project upwards in the operating position.

Looking now at the in Fig. 3 shown upper part 4, it is to be noted that preferred, as the embodiments shown here provide that the upper part 4, seen in the illustrated operating position, at least one laterally, preferably in the horizontal direction, projecting Oberteildruckplatte 7 for vertical support of the upper part 4 the background 16 has. In the preferred embodiments, as shown here, two upper-side printing plates 7 protrude from the respective upper part 4, in each case on opposite sides. The shell side walls 5 can extend vertically in the operating position, as shown here. Of course, it is also an inclination of this shell side walls 5 conceivable. Of course, the same also applies to the gutter side walls 6. However, it is favorable if at least one Upper side wall 5 and at least one, this associated gutter side wall 6 are aligned parallel to each other.

Preferred, as the embodiments shown here, provide that the upper part 4 has at least one grate support 9 for mounting or inserting at least one grate 10 of the channel 1 on or in the upper part 4. Through the grid 10, the surface waters can then pass through the upper part 4 into the gutter 3 of the lower part 2. However, the grid 10 prevents according to its mesh size and the ingress of stones and / or contaminants in the gutter 3. The grate holder 9 is preferably bounded by lateral boundary webs 8 of the upper part 4. Furthermore, the upper part 4, as also shown here, vibration-damping elements 11 as an intermediate layer between the upper part 4 and on or in the upper part 4 up or inserted or inserted or inserted grating 10 of the channel 1 have.

In preferred embodiments, such as the embodiments of the flumes 1 shown here, it can be provided that, viewed in the operating position, the drainage channel 3 has, at least in sections, a downwardly tapering cross section. This ensures a drainage speed in the drainage channel 3 that is as high as possible, even at low gutter inclines, so that as little sediment deposition as possible occurs in the drainage channel 3.

In the second embodiment according to Fig. 7 , which is otherwise constructed as the first embodiment, the gutter 3 for this purpose a sectionally V-shaped cross-section.

In both embodiments shown here, it is provided that the lower part 2 on both sides of the gutter 3 and laterally spaced from the gutter 3, preferably parallel, next to the gutter 3 extending side walls 12 having a, the gutter 3 at least partially surrounding, 13 Einfüllraum for the Limit filling of concrete laterally. As a result, the lower part 2 has a filling space 13 laterally delimited by the side walls 12, in FIG the concrete can be filled. This may be, for example, common site concrete or even a polymer concrete. Through this so created filling 13 results in a simple way of permanent attachment of the base 2 in the ground 16 or soil, which also favors a particularly simple and rapid installation of the channel 1. Preferred variants such as those shown here provide that the side walls 12 are fastened by means of connecting webs or connecting plates 14 to the gutter 3. The side walls 12 and / or the optionally present connecting webs or connection plates 14, connecting flanges 18 and / or end walls 19 can also comprise contact surfaces 15 for setting up the lower part 2 on the base 16 or on the support 23. Generally, it is advantageous if, as also realized here, the channel 1 at its end faces 17 of the gutter 3 connecting flanges 18 for attachment to connecting flanges 18 of the gutters 3 other channels 1 has. In the exemplary embodiments shown, connecting holes 38 are provided in the connecting flanges 18 through which the connecting flanges 18 adjacent channels 1 can be screwed or riveted together. Furthermore, it is favorable if the channel 1 at the end faces 17 of the gutter 3 end walls 19 to the end face of the filling 13 has. These end walls 19 may preferably be embodied in the form of the connecting flanges 18. In the exemplary embodiments shown, this is realized in a preferred embodiment in such a way that the connecting flanges 18 or end walls 19 which are respectively arranged on the end faces 17 of the channel 1 also act as connecting plates 14 between the drainage channel 3 and the side walls 12. It is particularly favorable in terms of an optimal seal and prevention of leaks when, as shown in the embodiments shown, in the connecting flanges 18 and end walls 19 each at least one passage opening 37 is arranged for concrete, which the gutter 3, in the operating position seen, at least in a lower region of the gutter 3 surrounds. This is achieved by the filling of the concrete in the filling chambers 13 in a simple manner that the front ends of the adjoining gutters 3 adjacently arranged channels 1 at least in its lower part completely are enclosed or cast in the common concrete body 33, whereby leaks in the connection region of adjacent channels 1 are prevented. In the Fig. 2 and 4 are also provided in preferred embodiments notches 39 can be seen, which can serve to mount assembly tools on the channel 1, for example, the channel 1 in the in Fig. 8 lower trench 31 shown. The notches 39 can, as shown, be carried out together with the passage opening 37 or separately.

In terms of a simple transport of the tops 4 and bottoms 2 of the channel 1 to the site is, as also realized here, a modular structure low. For this purpose, the channels 1 are preferably composed of prefabricated, a certain length having lower and upper parts 2 and 4. Each may be solid steel or other suitable material. In this sense, it is thus preferably provided that the upper part 4 and / or the lower part 2, at least the gutter 3 metal, preferably steel, or made of metal, preferably steel. In the embodiment shown here, the upper part 4 and the lower part 2 are each designed as a one-piece body made of steel. Of course, such one-piece body can also be made of a suitable plastic or other material, in particular another metal. The grid 10 is conveniently not fixed to the upper part 4, but removable from the grate 9, which does not necessarily have to be so.

In order to achieve a required in local circumstances length of a total clot, an arrangement with a plurality of successively arranged channels 1 may be provided, in which the gutters 3 of the channel 1 are connected together to form a continuous channel and poured into a common concrete body 33. The lower parts 2 of the channels 1 of such an arrangement, which are already inserted into the trench 31 and are connected to one another at their connection flanges 18 and via the common concrete body 33, are shown in plan view Fig. 14 shown schematically. The connection of the successively arranged channels 1 is carried out together Conveniently first of all about the connecting flanges 18. These can be screwed together or riveted together, for example by means of the connecting holes 38. Gluing or welding together is possible. After connecting the various channels 1 via their connecting flanges 18, the common concrete body 33 can be poured by filling the filling spaces 13 by means of concrete. The height of the side walls 12 also indicates the height of the concrete body 33. In this context, it is again favorable if the side walls 12 laterally delimiting the filling space 13 in the operating position each have lower edges 20, which are each arranged at a level below the lower end 21 of the gutter 3 and each have upper edges 22, respectively are arranged at a level above the lower end 21 of the gutter 3. In this way, at least the lower part of the respective gutter 3 when filling the concrete in the filling space 13 surrounded by the concrete, resulting in a simple but reliable sealing of the entire, composed of the various gutters 3 groove of the arrangement, without requiring additional sealing elements between the individual gutters 3 of each channel 1 must be installed. The waterproof substructure realized in this manner provides in a simple manner a permanent seal of the entire continuous channel. In this context, it is also advantageous if the gutter 3 at least 30%, preferably at least 40%, of their vertical extension in the area between the upper edge 22 and lower edge 20 of the side walls 12 and thus into the then finished cast concrete body 33 protrudes. At the connecting plates 14, connecting flanges 18 and / or end walls 19, as in Example Fig. 6 shown, angled ribs 40 may be arranged. These can serve as additional stiffening or a simple attachment of the side walls 12. The ribs 40 and also the contact surfaces 15 can be formed by forming or bending over corresponding marginal regions of the connecting plates 14, connecting flanges 18 and / or end walls 19. But they can also be welded or otherwise secured there.

As shown here, the side walls 12 may be grids in order to keep the total weight of the lower part 2 as low as possible in terms of good transportability. But it can also be provided without recesses continuous walls.

Also in the sense of a simple stackability of the lower parts 2 indentations 28 may be provided in the connecting plates 14 and connecting webs, connecting flanges 18 and end walls 19 at the lower end seen in the operating position. These indentations 28 advantageously have a width which is greater than the distance between the freely projecting upper ends of the gutter side walls 6 of the gutter 3. When the concrete is poured into the filling chambers 13, additional direct connections made of concrete between two adjacent filling spaces 13 in the sense of a common or continuous concrete body 33 are created via the concrete filling the indentations 28.

Based on Fig. 8 to 13 In the following, a method for installing inventive channel 1 in the ground is explained. It should be noted that the lower part 2 of the channel 1 is shown here only simplified and schematically, but in general can be designed as in the embodiments shown above.

Before discussing the more detailed steps of the method explained in detail, it should be noted that two essential core ideas of such methods are also conceivable in combination with other more detailed embodiments of the overall method. The first of these aspects provides a method for installing a channel 1 for removing surface water in a substrate 16, wherein the channel 1 at least one lower part 2, which has at least one gutter 3, and at least one in an operating position above the lower part 2 arranged upper part 4, wherein the upper part 4 and the lower part 2 are designed as separate components of the channel 1 and each supported separately on the ground 16. Another core idea provides a method for installing a channel 1 for the removal of surface water in a substrate 16, wherein the channel 1 at least one lower part 2, which has at least one gutter 3, and at least one arranged in an operating position above the lower part 2 upper part 4, wherein the lower part 2 on both sides of the gutter 3 and laterally spaced from the gutter 3, preferably parallel, next to the gutter 3 extending side walls 12 which define a, the gutter 3 at least partially surrounding the filling space 13, wherein in the filling space 13 concrete is filled.

In detail, such methods, as exemplified below, can be realized. Thus, for mounting the channel 1 in the ground 16, first a dug from the side edges 32 and the support 23 trench dug. The support 23 may, as already stated, consist only of the correspondingly prepared substrate 16 or be designed as a separate layer, for example made of concrete. On the support 23 then the lower part 2 can be placed with its contact surfaces 15 in the trench 31. In order to form a continuous channel, comprising a plurality of such channels, the individual lower parts 2, which are arranged successively in the trench 31, are connected to one another by means of their connecting flanges 18, for example by screwing, riveting or welding. This can be done before or after setting up the lower parts 2 on the support 23. Subsequently, the filling spaces 13 are filled with concrete, whereby a common, the individual parts 2 of the channels 1 interconnecting concrete body 33 forms in the manner described above. This is in Fig. 9 and in plan view in Fig. 14 shown. Following that, the in Fig. 10 shown cover 34 are placed on the upwardly open end of the gutter 3. Subsequently, the rest of the trench 31 is filled with backfill material 35, which can be compacted in a manner known per se. This state is then in Fig. 10 shown. As a next step, the support layer 29, for example, of an asphalt surface can then be applied to the backfill material 35 and the substrate adjacent thereto, as shown in FIG Fig. 11 is shown. As a next step, the cover 34 is then removed and the upper part 4 of the channel 1 is inserted so that the Upper side walls 5 overlap in the already described manner between the gutter side walls 6 come to rest and the Oberteildruckplatten 7 of the upper part 4 on the support layer 29 and are supported by this. Is this in Fig. 12 shown step completed, so then the cover layer 30 may be applied, for example in the form of fine asphalt, where it then comes to rest on the support layer 29 and also on the Oberteildruckplatten 7. It can, as in Fig. 13 shown between the cover layer 30 and the boundary webs 8 still seals 36 are introduced, which prevent ingress of water in this area. If the grid 10 is then inserted into the grate receptacle 9 of the upper part 4 of the channel 1 and, if appropriate, fastened therein, then the ready-to-use final state is as it is in Fig. 13 is shown reached.
