The lower portion comprises side walls (12) extending on both sides of the discharge channel and laterally spaced from the discharge channel, particularly parallelly extending next to the drainage channel. A filling space (13) is provided, which partially surrounds the drainage channel for laterally delimiting the filling of the concrete. An independent claim is included for an arrangement for removing of surface water.

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.

In the prior art, the lower parts usually consist of concrete drainage channels. In order to be able to mount these in the underground stable and in the desired orientation, great care and thus a lot of effort is required.

The object of the invention is to provide an easy-to-install flume of the type mentioned above.

This is inventively achieved by the lower part on both sides of the gutter and laterally spaced from the gutter, preferably in parallel, next to the Drain gutter extending side walls which laterally define a, the gutter at least partially surrounding, filling space for the filling of concrete.

By the invention, the lower part and thus the gutter can be relatively easily installed in the ground. After placing the lower part on a corresponding surface or support of the ground, the limited by the side walls of filling space with concrete, possibly polymer concrete, poured out, which in a simple manner a stable and permanent attachment of the base is achieved in the ground. The formwork required for the concreting process for limiting the filling space is already present in the form of the side walls on the lower part in the desired geometric matching to the gutter. In this context, it is advantageous if the side walls are fastened by means of connecting webs or connecting plates to the gutter.

In addition to the channel per se, the invention also relates to an arrangement with a plurality of successively arranged channels according to the invention, wherein it is provided that the gutters of the channels are connected to a continuous channel with each other and cast into a common concrete body. To connect the gutters or lower parts of the channels to a continuous channel, the channels may have at their end faces connecting flanges for attachment to the connecting flanges of gutters of other channels. If the individual lower parts of the channels are connected to one another via their connecting flanges, for example by screwing, riveting or welding, then a continuous concrete body can be cast by filling the filling spaces, which, in addition to the simple assembly, has the advantage that it is easy to do a complete seal of the continuous channel of the arrangement achieved without the need for separate sealing measures must be taken.

Based on Fig. 1 First, problems occurring in the prior art are exemplarily explained. 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 conventional manner on the support layer 29. The accumulating on the surface of the cover layer 30 surface water passes through a 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 away, 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 sum, cracking and destruction in the drainage channel 3 'or in the lower part 2', which are illustrated here in the form of the cracks 26 and 27, frequently occur due to the loads 24 and the side loads 25 in the prior art. Another problem of the prior art is the relatively complex structure in the ground 16. Thus, the executed in the prior art as concrete gutters bottoms 2 'individually aligned and secured in each case on lateral abutment eg concrete in their orientation.

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 principle, it should be pointed out that the upper part 2 and the lower part 2 can also be embodied in one piece and / or arranged directly resting on one another. In this, as well as other preferred embodiments, it is provided that the upper part 4 and the lower part 2 are separate components of the channel 1, which in the operating position separately from each other on the ground 16 are supported or supported. 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 moves relative to the lower part 2 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. It is, however, favorable if at least one upper side wall 5 and at least one gutter side wall 6 assigned thereto are aligned parallel to one another.

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 laterally limited from the side walls 12 filling 13, can be filled in the concrete. 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 embodiments shown are provided in the connecting flanges 18 connecting holes 38 through which the connecting flanges 18 adjacent mutually arranged channels 1 can be screwed together or riveted. 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 13 in a simple manner that the front ends of the adjoining gutters 3 adjacently arranged channels 1 are completely enclosed or encapsulated at least in its lower part in the common concrete body 33, causing leaks are also prevented in the connection region of adjacent channels 1. 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 at Lower part 2 at least the gutter 3 metal, preferably steel, or have 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. Conveniently, the connection of the successively arranged channels 1 with each other takes place initially via 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. As a result, at least the lower part of the respective gutter 3 is surrounded by the concrete during the filling of the concrete in the filling space 13, resulting in a simple but reliable Sealing the entire, composed of the various gutters 3 channel of the arrangement leads, without the need for additional sealing elements between the individual gutters 3 of the individual channels 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 pouring the concrete into the filling 13 are on the indentations 28 filling concrete and additional direct connections of concrete between two adjacent Einfüllräumen 13 created in terms of a common or continuous concrete body 33.

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 is a method for installing a channel 1 for the removal of surface water into 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 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, 13 filled in the filling space concrete becomes.

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, only from the corresponding prepared substrate 16 exist 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 part side walls 5 overlap in the already described manner between the gutter side walls 6 and the upper part pressure plates 7 of the upper part 4 rest 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.

In the 15 to 18 Now, a preferred alternative is shown, as at least two, preferably a plurality of lower parts 2 and their connecting flanges 18 can be interconnected to form a continuous groove. While it has already been mentioned at the outset that this is possible by screwing, riveting or welding or the like, the variant according to FIG FIGS. 15 and 18 how this connection can also be realized by inserting a connecting pin 41 in a connecting pin receptacle 42 and preferably clamped there. Fig. 15 shows a detailed view of a portion of a connecting flange 18 which is connected to the underlying non-visible connecting flange 18 by means of the connecting bolt 41 and the connecting pin receptacle 42. Fig. 16 shows the whole in a sectional view along the section line AA Fig. 15 , Here, the two adjacent to each other to be connected connecting flanges 18 of the lower parts 2 to be joined together are clearly visible. Fig. 17 shows the, preferably at least partially wedge-shaped, connecting pin 41st Fig. 18 shows the connecting bolt receptacle 42. The connecting bolt receptacle 42 may, as shown in this embodiment, be formed as a separate part which is inserted through corresponding recesses 45 in the connecting flanges 18 to be joined together and is supported with its support shoulders 43 on one of the connecting flanges 18, while on the other side of the connecting pin 11 is inserted so far into the recess 44 of the connecting pin receptacle 42 until a clamping connection between the connecting pin 41 and connecting pin receptacle 42 and thus between the connecting flanges 18 is reached. As an alternative to the exemplary embodiment shown here, it may of course also be provided that a corresponding connecting bolt receptacle 42 is fixedly arranged on one of the connecting flanges 18. Then only the other of the connecting flanges 18 must have a recess 45 through which the connecting bolt receptacle 42 can be inserted therethrough and then in turn a connection as shown in FIG Fig. 16 is shown by reaching the connecting pin 41 in the recess 44 of the connecting pin receptacle 42nd inserts. In principle, connecting pin 41 and connecting pin receptacle 42 may, of course, be formed very differently to the embodiment shown here. The connecting pin 41 and the connecting pin receptacle 42 may be preassembled in the variant shown here but also at a corresponding point of a respective connecting flange 18, to then be removed for connection of the connecting flanges 18 of this preassembly position to the in the FIGS. 15 and 16 make connection shown.

For the sake of completeness, it is noted that in the FIGS. 15 and 16 additional ribs 40 are also arranged in the upper region of the respective connecting flange 18. In this case, the connecting bolt 41, as in Fig. 16 shown to be able to push into the recess 44 of the connecting pin receptacle 42, recesses 46 are provided in these ribs 40 in the corresponding areas. Of course you could just as well omit the ribs 40 completely in this area.
