Definitions

  • the invention relates to a well with a flow channel at the bottom; see for example GB-A-1 443 052 .
  • Wells especially drain wells, should have a flow channel at the bottom so that impurities flowing in the pipes do not block the well.
  • the flow channel is a chute at the bottom of the well that leads from an inlet connection to an outlet connection.
  • the flow channel can be made for instance by injection-moulding the bottom of the well so as to have flow channels from the inlet connection(s) to the outlet connection. If there are several inlet connections, the flow channels join in the middle of the bottom of the well. This type of solution is described in WO publication 01/96777 , for instance. Making the bottom of the well by inject-moulding is quite expensive.
  • the locations of the inlet and outlet connections should be exactly determined in advance and making changes on the installation site is, in practice, not possible.
  • FI publication 76,159 describes a solution, in which a thick well bottom is formed with a thinner mid-section so as to have a bowl-like bottom.
  • a special drill is used to drill into the thick bottom a hole and a groove extending to the middle of the bowl-like bottom. Drilled flow channels from different directions then join in the middle of the bottom.
  • This type of solution is very difficult and expensive to implement. Making connections to the well on the installation site is especially arduous and difficult, because the connections require the use of a special drill.
  • the well of the invention is characterized in that the bottom of the well is cup-like and in the mid-section of the cup-like bottom, there is a flow guide protrusion so that the cup-like bottom and the flow guide protrusion together form a circular flow channel that directs the flow to circle along the edges of the bottom.
  • the essential idea of the invention is that the well has a cup-like bottom and in the mid-section of the cup-like bottom, there is flow guide protrusion so that the cup-like bottom and the flow guide protrusion together form a circular flow channel that directs the flow to circle along the edges of the bottom.
  • the idea of one embodiment of the invention is that the flow guide protrusion is arranged detachable from the bottom of the well.
  • the idea of a second embodiment is that a preform for an output connection is formed at the bottom of the well.
  • the idea of a third embodiment is that the flow guide protrusion has a flow guide bulge that is arranged to direct the flow towards the output connection.
  • the idea of a fourth embodiment is that the flow channel is inclined in such a manner that the flow is towards the output connection.
  • the invention provides the advantage that the drain well is simple and inexpensive to make. Forming connections to the well is fast and easy. Further, liquid and waste flow easily at the bottom of the well and the well is not easily blocked.
  • the connections are easy to form anywhere on the well circumference, i.e. it is not necessary to know the locations of the connections in advance when the well is made, but connection points can be made in the well on the installation site. This way, the well is especially well suited for renovations and retrofittings. By making the flow controller detachable, it is easy to clean and, if necessary, replace during maintenance.
  • Figure 1 shows a well bottom 1.
  • the well bottom 1 is cup-like, i.e. shallow, even in the middle and curves upward on the edges.
  • the bottom 1 can be made of a plate by thermoforming, for instance. It is also possible to make the bottom 1 by injection-moulding or rotational casting, for example.
  • An outlet preform 2 for an outlet connection is also formed to the bottom 1.
  • the bottom 1 and naturally the entire well can be made of polyolefin, such as polyethylene PE or polypropylene PP.
  • the bottom 1 and well can also be made of polyvinyl chloride PVC, for instance.
  • a flow guide protrusion 3 is mounted in the middle of the bottom 1.
  • the flow guide protrusion 3 is preferably made of the same material as the bottom 1. It is also possible to make the flow guide protrusion 3 from a plate by thermoforming, injection-moulding or rotational casting or in some other suitable manner.
  • the flow guide protrusion 3 can be fixed to the bottom 1 or it can be detachably mounted in the middle of the bottom 1.
  • the cup-like bottom 1 and the flow guide protrusion 3 together form a circular flow channel 4. This way, fluid flowing to the well flows along the circular flow channel 4.
  • the circular flow channel 4 is designed so that the flow rate of fluid in the flow channel 4 is sufficient to prevent the well from blocking.
  • the flow guide protrusion can for instance be a dome in shape.
  • a flow guide bulge 5 extending to the flow channel 4 is formed on the flow guide protrusion 3 at the location of the outlet connection. This way, fluid flowing along the circular flow channel 4 hits the flow guide bulge and is smoothly directed out through the outlet connection
  • an ascending pipe 6 is welded to the bottom.
  • an outlet connection 7 is welded at the location of the outlet preform 2.
  • the well is ready for transport to the installation site.
  • An outlet pipe is connected to the outlet connection 7. If desired, the outlet pipe can be directly connected to the outlet preform, in which case the above outlet connection 7 is not needed.
  • the term outlet connection refers to an outlet preform 2, outlet connection 7 or outlet pipe.
  • inlet connections 8 can be fastened to the well as shown in Figure 4 . It is thus possible to determine the locations of the inlet connections 8 on the installation site. This way, the well is extremely versatile and well suited for use in renovation and retrofitting.
  • the inlet connections 8 can naturally also be fastened in the factory before the well is transported to the installation site.
  • Inlet pipes are connected to the inlet connection 8. If desired, the inlet pipes can be directly connected to the well, in which case the inlet connection 8 is not needed.
  • the term inlet connection refers to either an inlet unit or inlet pipe.
  • the inlet connection is preferably located higher than the outlet connection. Fluid then flows from the inlet connection along the flow channel 4 to the outlet connection.
  • the flow channel 4 is preferably inclined towards the outlet connection. Fluid then flows easily to the outlet connection.
  • the flow guide protrusion 3 is made detachable, it is possible to detach it during well maintenance work to facilitate cleaning and servicing.
  • the flow guide protrusion 3 can also be made to be in the same structure with the bottom 1 by forming the bottom 1 and at the same time the flow guide protrusion 3 to it from a plate by thermoforming, for instance. The manufacture of the well is then simple and inexpensive.
  • the flow guide protrusion 3 is located in the middle of the bottom 1, but if desired, the flow guide protrusion 3 can also be located asymmetrically in the mid-section of the bottom 1 in such a manner that the flow channel 4 is narrower in part.
  • the well is especially well suited for use in sewer systems and rainwater systems.
