Abstract

The channel (G) has an outlet (A) and an inlet (Z) comprising a round channel body (1) with an outer delimitation (4), and a flow connection provided between the inlet and the outlet. A ledge (V) is provided over a circumferential region of the body, where the region overlaps at preset, different inlet-tie angles of the inlet. The ledge is adapted to the delimitation. The ledge guides up to the outlet, and is attached to the inlet. The ledge rotates along the entire outer delimitation. The channel body is a plastic or metallic body or made of concrete.

Description

The invention relates to a channel according to the preamble of patent claim 1.

There are manure channels with berms known, especially in faecal wastewater, especially in Germany applicable requirements to meet even in case of heavy wastewater attack or changing directions of supply clear flow conditions. A full mountain is defined under berms, for example, by a substantially U-shaped cross-section, which is consistent throughout the Vollberme up at least with the cross section of the nominal diameter of the inlet or outlet. A full mountain is for example a requirement for greywater and black water. Since a berm is needed in the manhole with berms between each inlet and the outlet, and the tethers of the inlets vary depending on installation conditions, a variety must be made in terms of tying angle of different channels (possibly even shafts with channels) and kept in warehouses. This results in a high logistical effort in the production and storage and expensive each channel or each shaft. In addition, the production costs increase, the more inflows are provided, since for each inflow a separate Berme must be formed and blended with another Berme. As a result, the flow conditions despite a berm or Vollberme but the less favorable, the more feeds are provided, since the intersections of the berms form local cross-sectional extensions that are detrimental to a uniform flow.

Inter alia, channels for so-called Varioschächte or Varioschächte with channels are also known in which the Anbindewinkel the feeds are freely selectable, and each feed as needed, possibly only on site, drilled, formed and sealed. The channel comprises a cup-shaped channel body with an outer boundary and a flat pot bottom. However, the flow conditions in the pot are less favorable than in berms when sewage flows from several inlets, as it creates dead zones and / or flow turbulence. Although this solution is more cost effective and logistically easier to master, but due to the absence of Vollbermen meets the requirements specifically applicable in Germany for gray water and black water not or only conditionally.

The invention has for its object to provide a low-cost producible flume, which is universally applicable for different feed tying angle, and always ensures perfect flow conditions to the process, even if more than one inlet is provided.

The stated object is achieved with the features of claim 1.

The at least over a predetermined peripheral area without interruption to the end of continuous, along the outer boundary circumferential Berme is equally usable for different Anbindewinkel of inlets, which then open laterally into the berm. This facilitates the production of the channel considerably, avoids logistical problems for different inlet tying angles, and above all ensures favorable flow conditions, regardless of the number and tying angles of the inlets. If several feeds or just one feed already formed in the production of the channel body, this can be realized with simple technical measures, since the Berme is always the same. Similarly, can be in the channel with a preformed expiration of or the inlets can be placed as needed later and connect laterally to the berm. It is also possible to preform several feeds blindly, and later to uncover only the used feed (s) as needed.

Although it can indeed form the channel with only one laterally opening into the berm inflow; As a rule, however, at least two inlets under different tying angles open laterally into the berm. Further, an inlet at any point along the circumference can be led into a fully circulating berm except when drained, although in practice feeds are usually needed only within an approximately 180 ° spanning peripheral area which is approximately symmetrical to the axis of the drain and this opposite. In any case, all infeeds use the bermed to the outer boundary, leading to the expiration together, in a full-wrap Berme much like a built between several one-way roundabout. The favorable flow conditions result from the continuous course of the berm.

The berm can be a half-mountain, but is suitably a full mountain, and fulfills as Vollberme the specifically applicable in Germany requirements for gray water and black water. The concept according to the invention is, for example, such that the channel body is produced with the outlet and the berm and then in a special Device (or only locally) each inlet with the required Anbindewinkel is formed so that it opens laterally into the berm, so that thus all feeds share the Berme.

In an expedient embodiment, as mentioned, the berm runs completely along the entire outer boundary, and the continuous internal boundary of the berm is formed by the outer wall of the baffle, which rises like an island in the channel body and cleanly guides the flow in the berm ,

In an expedient embodiment, the full-beak is drop-shaped in a plan view, wherein the tip of the drop points into or to the drain. This leads to an even better flow control to and into the process, regardless of how large the waste water is and from which feed wastewater is introduced.

In one embodiment, the inlets and outlets in the outer boundary open approximately radially into the berm. Incoming sewage seeks in the berm the path of least resistance.

In a favorable embodiment, at least one inlet is guided angled relative to a radial orientation laterally into the berm, preferably at most almost tangentially. In this way, a certain inflow direction is forced into the berms entering the inlet through the inlet, which improves the flow.

In an expedient embodiment, at least one inlet and the outlet are preformed at predetermined positions, preferably with outwardly projecting pipe sockets. It can be easily connected to a supply line or a derivative. Optionally, even another or further pipe sockets are blind preformed, which are opened only when needed, e.g. for frequently required inlet tying angles.

In order to cope with a single type of channel body requirements with respect to freely selectable numbers of inflows and inlet tethers, in another embodiment, only the flow is preformed and the inlets at selectable positions in the outer boundary, eg by drilling, subsequently formed. For this purpose, even selectively usable Anbindewinkel markings and / or predetermined breaking points for inlets may be preformed, which facilitate the exposure of the respective inlet either at the manufacturer or at the installation, the respective inlet pipe socket or only a pipe can be used with a seal or welded or glued.

The full mountain is approximately U-shaped in cross section. The transition radius in the outer wall of the Vollberme should be expediently smaller than the transition radius in the inner wall. This is not only important for good flow conditions, but facilitates the lateral connection of the respective inlet. It could even be provided an approximately rectangular transition at least in the outer wall.

Conveniently, the outer and inner walls of the Vollberme extend beyond the inlet and / or drainage outlets upwards, so that no wastewater swirls upwards in case of surge-like sewage attack.

The guide body is suitably closed at its top and formed with a non-slip surface. A closed guide body increases the stability of the channel and can be conveniently used during a walk-through. However, it is not absolutely necessary to close the baffle at the top.

In an expedient embodiment, in particular when the channel is a plastic or metal molding, the guide body is a dome ascending from a bottom side of the channel body. To stabilize the channel, and also to its better embedment in the ground or more stable support on the foundation, in the dome from below a stiffening ribs exhibiting insert body can be used, which has a bottom side of the channel body occlusive bottom plate. Alternatively, the dome could also be made more stable with integrated stiffening ribs and, if appropriate, closed at the bottom.

In the Vollberme an expedient above the inner wall and / or the outer wall bearing shoulder is provided. The support shoulder (s) is or can be used to insert additional components of the coagulation.

In an expedient embodiment, a circumferential positioning toothing is provided in the region of at least one support shoulder. The positioning toothing, with or without support shoulder, can also be used for attaching and defining further equipment components of the channel.

In an expedient embodiment of the channel, at least one inflow or outflow mouth, a partition wall extending up to the bottom of the full boilers and / or deflection surface is inserted into the full body on one side. This partition wall and / or deflection surface may be contained in an insert part, which, preferably, on the support shoulders and / or in the respective positioning toothing is fixed. For example, a dividing wall adjacent to an inlet mouth prescribes a certain inflow direction into the full inlet of the outlet. A partition positioned adjacent to the drain port prevents an incoming flow from flowing past the drain port to the other side into the full tank. A deflection surface, either in combination with a dividing wall or at the same time acting as a partition, can improve the flow conditions in the Vollberme or from the Vollberme. With such dividing walls and / or deflection surfaces, it is possible to neutralize, as it were, a peripheral section of the full-berm, which is not required during operation, and therefore remains clean. The partition or deflection is of course also usable when the inlet or the inlets are exposed only later and as needed.

In another embodiment, the Vollberme is completely or partially covered by at least one insertion lid on its upper side. The lid can be removed or moved if necessary. For example, the lid covers an unused portion of the full-bite. A further advantage of the insertion lid is that it, if appropriate in combination with the upper side of the guide body, forms a standing surface during the inspection of the shaft. This stand can be structured for safety and / or stability reasons. The loading lid, which covers, for example, a portion of the full-bough that is not used for the flow, also prevents the falling in of contaminants in this section. It can be used a cover covering the entire whole berme, or it can, depending on requirements, several such lid are inserted, each of which covers only a portion of the open side of the Vollberme.

In one embodiment, the channel body is combined with a wellhead or well, i. attached and sealed. Alternatively, the channel body is integrally integrated into a shaft or shaft section. The channel body may be a plastic injection-molded part, a deep-drawn part, a blow-molded part, rotational molding or the like. Also, a metal molding is conceivable. Alternatively, the channel body is made of concrete or cast iron, or bricked for example of bricks and optionally lined with clinker or tiles.

In the formation of the channel of plastic is particularly suitable for injection molding PE and PP. The channel is either designed so that the prescribed slope is integrated to the drain, or the channel is installed so that the slope arises. For example The bottom of the whole mountain is in a plane inclined to drain below about 2 °. In the event that only a diametrically oriented to the flow inlet is provided, or the channel is designed only for this application, could be formed as Vollberme also a straight puncture through the central guide body, or in addition to a circular course of Vollberme. The puncture can, if not required, be blocked by inserts inserted, or it is shut off the outer bypass in the course of the Vollberme accordingly.

A flume G for a shaft S is in the Fig. 1 to 3 For example, a plastic injection-molded part and integrally formed with the shaft S or a manhole section. Alternatively (not shown), the channel G could be formed separately from the shaft S or a shaft element and attached to this subsequently. The channel G has in the embodiment shown, for example, a cup-like round channel body 1, in the outer boundary of a sequence A in the form of a molded pipe socket 2 is formed. Further, a preformed inlet Z may also be formed in the form of a pipe socket 2, for example, offset by about 120 ° to the sequence A. Finally, a second inlet Z may in turn be provided offset, for example, approximately is formed radially later in the outer boundary 4, that a circular orifice 3 is present. The mouths of the inlets and outlets Z, A are in the circumferential outer boundary 4 to the inside a Berme V, preferably a Vollberme V, nestles, which in the Fig. 1 to 3 approximately follows a full circle and has an inner boundary 9, which is formed by an outer wall 8 of a here approximately circular guide body K. The guide body K is island-shaped upward from a bottom side 12 of the channel body 1, so that the circumferential berm V or the full berm with the laterally opening inlets Z and the outlet A defines a circular traffic-like system. The guide body K may be closed at its top 6 and has in the berm V a circumferential support shoulder 7. The outer boundary 4 may also have a circumferential support shoulder 5 in the berm V, which preferably lies at the same height as the support shoulder 7.

In Fig. 2 is the circumferential berm or Vollberme concentric to the center of the approximately circular channel body. 1

In Fig. 3 It can be seen that in the guide body K, which is upwardly from a bottom side 12 of the channel body and hollow with a lower opening, a stiffening ribs 15, 16 having insert body 13 is inserted, which has a bottom plate 14, which is the bottom side 12 of the channel body 1 complements and closes the opening of the guide body 6.

The Berme or Vollberme V has according to Fig. 3 a U-shaped cross section, with an approximately semi-circular base 11 and approximately vertical inner and outer walls 18, 20 formed by the outer and inner boundaries 4, 9 of the channel body 1, wherein the inner and outer walls 18, 20 after extend above the side mouths 3 of the inlets and the outlet out to the support shoulders 7, 5. Conveniently, a transition curvature 17 is formed in the inner wall 18 with a larger transition radius, as a transition curvature 19 from the base 11 in the outer wall 20. Alternatively, the transitions could also be formed approximately at right angles, so that the Berme or Vollberme V to the bottom in possessed approximately constant cross-section. The lower mouth edge is approximately flush with the base 11, while the upper edge of each mouth 3 at a distance below the support shoulder 5 is located. The flow cross section in the Vollberme V corresponds at least to the cross section of each orifice 3 and the cross section of each pipe socket 2 corresponding to the nominal diameter.

Fig. 4 illustrates an embodiment in which the course of Vollberme V drop-shaped, to achieve in the sequence A more favorable flow conditions. The inner boundary 9, as well as the outer boundary 4 of the berm or Vollberme V in sections 4 ', 9' aerodynamically designed to define the drop shape, the tip of which is indicated at 22, for example in alignment with the center of the mouth of the process A. In Fig. 4 no inlets are indicated. Optionally, each feed is formed only as needed. The number of feeds can be arbitrary, as well as their tying angle to the Vollberme V.

In the Fig. 1 to 4 the inlets Z and the outlet A are oriented approximately radially to the center of the channel body 1. It would alternatively be possible, at least to select the orientation of inlets Z deviating from a radial orientation to a maximum of a tangential orientation in order to force a certain inflow into the berm or Vollberme V, such as in Fig. 8 shown. There, the pipe socket 2 of the sequence A is similar to a funnel, while the pipe socket 2 of the inlets Z Pipe Bend 36 have to force an angled, almost tangential lateral inflow.

In the embodiment of Fig. 5 are alternatively or in addition to the support shoulders 5, 7 extending in the circumferential direction of the positioning teeth 23, 24, for example in the form of upstanding tabs with intermediate distances, provided that can be used to position inserts E in the channel G. In the embodiment in FIG Fig. 7 are the positioning teeth 23, 24, so to speak, as a lying tooth profile with a finer pitch than in Fig. 5 designed to be able to selectively position and fix insert parts E.

In Fig. 5 For example, an insert E on the support shoulders and / or the positioning teeth 23, 24 is fixed on one side of an orifice 3 of a formed inlet Z, which defines a the Vollberme V-filling partition 25 and a guide surface 28. The partition 25 separates the in Fig. 5 Overlying area of the berm opposite the inlet Z. The guide surface 28 directs from the mouth 3 in the Vollberme V entering wastewater Fig. 5 to the left to drain A to. In an alternative, not shown, only the partition wall 25 could be provided or only a guide surface 28 with partition wall function.

Similarly, an insert E is installed on one side of the drain A, although consisting of a partition wall with guide surface or only of a partition, so that the in Fig. 5 overlying and over more than 180 ° extending area of the berm or Vollberme V is separated, and only the lower area in Fig. 5 used for wastewater. The upper area could be covered by an insertion lid 31, which is supported for example on the support shoulders 5, 7 and, preferably, together with the top 6 of the guide K forms a suitably non-slip trained floor space when walking the shaft.

In the Fig. 5 and 7 For example, the inlet Z is formed by drilling as required. The channel body 1 could at its outer boundary 4 prepositioned Anbindewinkel markings 29 and 30 have predetermined separation points to form feeds with different attachment angles as needed can. The in the Fig. 5 and 7 shown inserts E can be removed at any time or implemented depending on the selected Anbindewinkel. In Fig. 7 the insert parts E are formed with overhead plates. The example usable insert parts E are in detail from the Fig. 6a to 6c refer to.

In Fig. 6a is in the insert E, the partition 25 combined with the guide surface 28. An end 26 matches the positioning toothing 23 of FIG Fig. 5 while an outboard end 27 is insertable into the locating tooth 24. The lower ends of the guide surface 28 and the partition 25, which are blended together along a line 34, are formed scoop-like or wing-shaped, as indicated in the areas 32, 33, to ensure a favorable and turbulence poor flow deflection. The insert E in Fig. 6a is symmetrical, for example, so that it can be placed on either side of an orifice 3 and the drain A.

The insert E in Fig. 6b is on the other hand designed to be in the channel G of Fig. 7 can be used. The end 26 'serves to abut on the positioning toothing 23 and to rest on the support shoulder 7, while the end 27' can be brought into engagement with the outer positioning toothing 24. The insert E here combines the function of the partition wall 25 and the guide surface 28, but is not symmetrical, but so that it can be placed only on one side of an orifice, in contrast to the insert E of Fig. 6a ,

Fig. 6c illustrates a very simple embodiment of an insert E, which is formed only as a flat partition 25, with an upper support plate 35 which is fixed to the ends 27 ", 26" on the support shoulders 5, 7. Optionally fit the inserts E with a slight sliding fit in the berm or Vollberme V, or they are along their edges equipped with sealing elements, for example in two-component technology. To fix the respective Insert E could also serve not shown fasteners, such as screws or the like.

The in Fig. 7 The insertion lid 31 shown either adjoins the inserted inserts E, or rests against them in order to secure them. Also, the insertion lid 31 could be fixed by fasteners, not shown.

In the event that the channel G is not integrally formed with the shaft S, but is connected to this, an outer flange 21 may be provided, in the region of the channel G is connected to the lower edge of a shaft or shaft portion and sealed thereto. The channel G need not necessarily have a circular shape, but may have any geometric shape, but, suitably, the berm or full mountain at least approximately follows a circle or approximately the drop shape of Fig. 4 has.

As a rule, feeds Z are formed within an approximately 180 ° spanning circumferential region of the channel body 1, which is opposite to the outlet A and z. B. is symmetrical to the drainage axis. The berm or full berms V could therefore extend (not shown) only over this peripheral area and then on only one side to the outlet A, similar to the Fig. 9, 10th shown.

For channels G where inlets Z are to be formed only between about 9:00 am and 12:00 pm positions based on a 6:00 am position of expiration A, or only between about 12:00 pm and 3:00 pm positions, (not shown) the berm or Vollberme V also extend on only one side over a limited peripheral area to the outlet A and be nestled inside the outer boundary 4. These principles could also be combined, e.g. with a respective section Berme or Vollberme V, which is nestled on each side to the outer boundary 4 and leads to the process A.

An example of this show the Fig. 9, 10th for a channel G with fixed and diametrically opposite inlets and outlets Z, A, between which a puncture 37 (also suitably a Vollberme V) through the baffle K and a clipped to the outer boundary 4 Vollberme V over a little more than 180 ° extends. There Walweise further feeds Z can be formed laterally einmündend.

The channel G according to the invention is first with a fixedly positioned sequence A and the berm or Vollberme V against the outer boundary 4 without inlets Z. (or with a maximum of one inlet Z). Then, subsequently, either already at the manufacturer, or only at the installation, feeds Z depending on demand formed with the desired connection angles in the outer boundary 4 so that they open laterally into the Vollberme V, eg by drilling and gluing or welding of pipe socket, or optionally by Inserting pipe sockets or feed pipes into feed-through seals which are inserted into an inserted bore.

The channel in almost every case use several lateral Berme or Vollberme V inflowing inlets Z, the directly to the outer boundary 4 or optionally with an intermediate distance Berm or Vollberme V together for transferring the wastewater (gray water or black water) in the sequence A ,
