Definitions

  • the invention relates to a channel according to the preamble of patent claim 1.
  • 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.
  • channels for so-called VarioMchte or Varioclothchte 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.
  • 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.
  • 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 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.
  • 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.
  • 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 ,
  • 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.
  • 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.
  • 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.
  • 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.
  • only the flow is preformed and the inlets at selectable positions in the outer boundary, eg by drilling, subsequently formed.
  • 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.
  • 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.
  • the guide body is a dome ascending from a bottom side of the channel body.
  • a stiffening ribs exhibiting insert body can be used, which has a bottom side of the channel body occlusive bottom plate.
  • the dome could also be made more stable with integrated stiffening ribs and, if appropriate, closed at the bottom.
  • the support shoulder (s) is or can be used to insert additional components of the coagulation.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the channel body is combined with a wellhead or well, i. attached and sealed.
  • 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.
  • the channel body is made of concrete or cast iron, or bricked for example of bricks and optionally lined with clinker or tiles.
  • 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.
  • the bottom of the whole mountain is in a plane inclined to drain below about 2 °.
  • 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
  • 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.
  • 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.
