Description

DRAINAGE-SYSTEM CHANNEL

description

The invention relates to a system for draining traffic areas, which has a flat gutter system with a plurality of gutter inlets. Known drainage channels essentially consist of a channel body with one or more covering grates, the surface water is taken up by the covering grates locked on the channel body and removed by means of the channel body. The collected water or other liquids are transferred from the gutter system to a conventional sewer pipe. The gutter system is thus only an intermediate station for draining the surface water into the already necessary sewer pipe.

Different requirements are placed on the gutter body. On the one hand, it should be sufficiently stable together with the cover grate, for example, to allow traffic areas to overrun vehicles, and on the other hand, the gutter system should be easy to clean and inexpensive to produce. In the known gutter systems, the rust must be removed for thorough cleaning of the gutter body. In order to ensure the necessary traffic safety, especially in case of overruns, the grate must be stably fixed in the gutter body. On the other hand, it should be easy to remove, to allow easy cleaning.

To derive the surface water in the gutter system a sufficient channel cross-section is required, which is usually achieved by appropriate heights of the channel body with slender gutter walls.

In order to guarantee the stability of the channel walls, especially against horizontal forces from traffic and physical influences (thermal expansion). In addition to the foundation, expensive backrests are required during installation, which in turn affect the connection of paved or asphalt traffic areas.

The invention has for its object to provide a shallow gutter system that can handle a high water supply despite flat design even at the usual width of the system and easy to clean at high traffic safety, inexpensive to manufacture and install.

This object is solved by the features of claim 1. The essence of the invention is to provide an elongate flat receiving inner element is provided, which is integrally formed and thus has both a traversable rust-like upper side, and arranged below this basin-like receiving area, which receives the collected water and this via a drain on the drained bottom point in a drain pipe element.

The actual drainage channel is formed by the assembly of a plurality of elongate female interior elements. By draining each of these elements independently of the adjacently located element into a drainage piping system via said drain, with adequate sizing of the piping system, a very large amount of water can be handled despite the slender design. Since the top of the female member is formed with webs rust-like, no separate cover grate is required. That is, problems caused by the traffic-proof locking and unlocking of the grating are completely avoided. Nevertheless, a simple cleaning of the gutter system can be ensured because due to the fact that each element is provided with its own drain, trapped between the webs dirt and other objects are easily solved by suitable cleaning elements such as high-pressure cleaner or mechanical cleaning equipment with Absaugmöglichketen. Suspended or fines are flushed through the drains of the receiving element in the pipe system and disposed of by flushing, if necessary.

Advantageously, the receiving inner element and / or the drain piping element is provided with a connecting piece which is connected to the drain or can be connected. Such a nozzle provided on the receiving element or drain pipe element may also be telescopically formed, or a separate telescopic nozzle may be placed on one of these nozzles in order to be able to easily compensate for height differences between the receiving inner element and the drain pipe element. Suitably, the diameter of the nozzle are coordinated so that they can be inserted into each other. By such a design of the nozzle, the distance between receiving inner element and drain pipe element may vary. This is of great importance, especially if larger traffic areas are to be drained, where there is little or no slope. In this case, the drainage channel, which is formed from a plurality of receiving inner elements, have no or only a very slight slope. Nevertheless, in order to be able to cope with a high water supply, it is necessary that the drainage piping system below, which is also composed of a multiplicity of drainage pipe elements, be provided with a sufficient gradient, which is in principle not a problem, since it moves below the surface becomes. Due to the different slopes thus resulting over the length of the overall system different distances between the receiving inner element and the drain pipe element, which can be easily bridged in the manner described.

To bridge different distances accordion-like neck can be provided, which can be extended to different lengths. In order to connect the elongated female elements easily at their ends together, guides can be provided. Advantageously, these guides ensure a connection of adjacent elements in both the vertical and in the horizontal direction. According to the design selected in the specific embodiment, the guides are realized by projections, of which there is a first projection in the middle of the end face of the elongated receiving inner member, and on the opposite side two provided in the outer region second projections. The said first central projection thus engages in the juxtaposition of the receiving inner elements between the two further mentioned second projections. The projections engage in recesses, over which in the vertical direction, a portion of the receiving inner member is formed. Thus, not only in the horizontal but also vertical direction results in a definition and exact alignment of the adjacent receiving inner elements. This design is described in detail with reference to the specific embodiment and further has the advantage that it can be produced in a casting process without core or lost molds.

It may therefore be advantageous to provide an overflow on end walls in an upper region, so that above a certain level of liquid, a receiving inner element can drain into the adjacent one.

A roadworthy anchoring of the female elements is particularly ensured for high and fast traffic load through the anchoring elements. These can advantageously be provided directed vertically downwards on the outer longitudinal sides of the receiving inner element and provided with horizontal projections and Eckaussteifungen for load distribution. The projections should ensure anchoring in the concrete foundation. Furthermore, recesses may be provided on these support elements. The webs on the top of the receiving inner element, which allow entry or driving only, are advantageously designed as longitudinal webs in the longitudinal direction of the element. Advantageously, these are arranged offset, which improves the ability to drive over with narrow tires, such as racing bikes or strollers. The webs can be arranged offset in the longitudinal and in the transverse direction. The longitudinal webs can have different lengths. The arrangement of the webs can be provided so that fields result in the longitudinal direction, wherein the longitudinal webs can be arranged offset from field to field in the transverse direction. In principle, the distance of the webs can be varied, but this is generally not preferred. In the preferred specific embodiment, the longitudinal ribs of different length are arranged such that, viewed from above, one field alternates in O-shape with an adjacent field in X-shape. In a so-called O-field, the longest longitudinal ridge is located in a central region, whereas in the adjacent X-field the shortest ridge is provided here. Furthermore, the longitudinal webs are provided at the same distance, but offset from field to field in the transverse direction to improve the trafficability, to prevent track formation to ensure traffic safety. This configuration will be described in more detail with reference to the preferred embodiment.

The claimed dewatering system does not have a separate cover grate nor does it have any edge protector, making it inexpensive and has a number of advantages already described. The arranged below the actual gutter element drain piping system can be inexpensively made of plastic, a connection with the drain of the gutter elements can be made via recesses on the top, which can be drilled only during installation, so that initially a conventional simple plastic pipe can be laid, and only corresponding recesses are drilled out during the installation of the receiving element elements, which are then connected to the outlet of the receiving inner elements. However, prefabricated pipe elements are advantageous to the construction site minimize. At least one face of the entire finished drain pipe can be used for inspection shafts and maintenance openings.

The invention will be described in detail with reference to a concrete embodiment.

In the preferred embodiment explained in more detail, it is a receiving inner element 1 of ductile cast iron, which is connected to a drain pipe element 10 made of plastic. Fig. 1 shows the element in plan view. Good to see are differently long running longitudinal webs 2 and the bottom 3 of the gutter element. Furthermore, the central drain 6 can already be seen, as well as flow openings 7 between the longitudinal webs 2, which ensure drainage between the longitudinal webs 2 to the drain 6.

Horizontal and vertical guides 4 and 5 can still be seen on the end faces of the element. However, guides will be described in greater detail in particular with reference to FIGS. 9 and 10.

Figure 2 shows the marked cross section through the receiving inner element according to the invention 1. Good to see the central drain 6 and in the outer area bearing and anchoring tabs 8, which have Eckaussteifungen 12. These support and anchoring tabs 8 are better seen in Fig. 3, from which the recesses 9 of the support and anchoring tabs 8 are easy to remove, which ensure a secure anchoring of the receiving inner member 1, for example, when using a concrete foundation. The support and anchoring tabs 8 are provided with lower horizontal projections 11, which are further illustrated in Figures 5 and 6 and ensure the anchoring of the receiving inner member 1 and improve support. The bottom 3 of the receiving inner element 1 is slightly inclined towards the central drain 6 in order to ensure the most complete possible drainage of the element.

The connection of the receiving inner element 1 with the underlying drainage pipe element 10 is well shown in FIG. 4 can be seen. The drain piping element 10 is provided with a bore 14 into which a Drain 6 surrounding nozzle engages. In this variant of the embodiment, the longitudinal ends of the receiving inner element 1 are designed so that they are laying aids 15 and 16, as shown in FIG. 3, which facilitate joining of adjacent elements.

Variants with and without slope of the bottom 3 and different pipe diameters can be seen from the cross sections 5 and 6. In principle, the bottom 3 can be designed with a slope in the transverse direction and optionally in the longitudinal direction in order to improve the drainage.

Alternative configurations of the surface of the receiving inner element 1 are shown in FIG. 7. It can webs of different shapes straight, kinked or find use in waveform, suitable webs of different lengths are used. Advantageously, the webs are arranged so that in no direction of travel results in a longer uninterrupted gap. For example, in combination with the web distances, the gaps should prevent the intervention of slender tires.

The design shown in Fig. 1 can therefore be improved by displacing the longitudinal webs in the transverse direction. Such a variant is shown by way of example in FIG. 8. In this variant, only straight longitudinal webs are used, which however have different lengths and are offset in the transverse direction. As a result of the design, as viewed from above, fields result from longitudinal webs which are separated from one another by distances which result in recesses substantially in the transverse direction. In this design, fields which basically have an o-shaped form and adjacent fields with a substantially x-shaped form are created. The longitudinal webs have a constant distance in the transverse direction, but are offset from field to field to each other. In the so-called O-fields, the longest longitudinal ridge is arranged in a central region, whereas in the so-called O-fields. X fields in this area the shortest bridge is arranged. This design has proven to be extremely beneficial.

Figures 9 and 10 show a variant of the design of the longitudinal end faces, so to speak, the end faces of the receiving inner element. In a lower region of the receiving inner element 1, a central projection 24 is provided on one side, whereas in each case a second projection 25 is provided on the opposite side in the outer region. When nesting of adjacent elements of the central first projection 24 between the two second outer projections 25 is arranged. Between these two second projections 25, a recess 26 is thus arranged, which corresponds to the shape of the first central projection 24. Accordingly, two recesses 27 are arranged on both sides of the central first projection 24, which correspond to the shape of the second projections 25. The recesses 26 and 27 are chosen so that an end wall 28 of the front end of the receiving inner member 1 is arranged over this. Thereby, it is achieved that two adjacent mated female inner members 1 are fixed not only in the transverse direction by the insertion of the central first projection 24 into the recess 26, but also in the vertical direction, since both the central first projection 24 and the second projections 25 are vertical are blocked upwards, so that an exact alignment and definition of adjacent receiving inner elements 1 is ensured.
