Definitions

  • the invention relates to a well which includes a well bottom and a wall and at least one outlet connection and in the bottom of which well there is provided at least one flow channel at least for the outlet connection.
  • the invention also relates to a well bottom which is provided with at least one flow channel at least for the outlet connection.
  • Wells in particular sewage wells, shall comprise, at the bottom thereof, a flow-guiding channel, by which incoming flow into a sewer is guided to an outlet connection from the well. Thanks to the flow channel impurities flowing in pipes do not block the well.
  • the flow channel may be provided, for instance, by die-casting the well bottom such that it comprises flow channels from an i nlet connection or inlet connections to the outlet connection. If there are several inlet connections, the flow channels meet in the middle of the well bottom.
  • a solution of this kind was disclosed, for instance, in WO 01/96777 . It is relatively expensive to produce the well bottom by die-casting.
  • the locations of the outlet connection and the inlet connections are to be determined precisely in advance, and, in practice, changes are not possible to make on the construction site.
  • Publication FI 76159 discloses a solution, in which there is provided a thick well bottom, the centre of which is formed thinner such that the bottom is like a bowl.
  • the thick bottom is drilled with a special drill to provide a hole and a groove extending to the centre of the bowl-like bottom. In that case the flow channels drilled from different directions meet in the middle of the bottom.
  • This solution is very cumbersome and expensive to implement. In particular, it is cumbersome and difficult to make connections to the well on the installation site, because a special drill has to be used for making them.
  • Publications NL 1000840 and GB 1443052 disclose a well, the bottom of which is like a cup, and in the mid-section of the cuplike bottom there is arranged a flow guide protrusion such that the cuplike bottom and the flow guide protrusion together form a circular flow channel, whereby the flow is guided to circulate along the edges of the bottom.
  • Publication WO 2004/007857 also discloses a solution of this kind.
  • publication WO 2004/007857 discloses that the flow guide protrusion comprises a flow guide bulge that is arranged to guide the flow towards the inlet connection.
  • the object of the invention is to provide a novel well and a novel well bottom.
  • the well of the invention is characterized in that the flow-forming part of the well bottom consists of a plate that is formed sloping towards the centre of the well bottom in other parts except for the flow channel.
  • the well bottom of the invention is characterized in that the flow-forming part of the well bottom consists of a plate that is formed sloping towards the centre of the well bottom in other parts except for the flow channel.
  • the well bottom consists of a plate that is provided with at least one flow channel at least for the outlet connection. In other parts, except for the flow channel, the plate is formed sloping towards the centre of the well bottom.
  • inlet connections holes are drilled in a well wall, when necessary, slightly higher up than where the hole for the outlet connection is.
  • the well bottom is funnel-like and from the centre of the funnel-like bottom starts a flow channel to the outlet connection, whereby the locations of the inlet connection may be selected almost freely.
  • the funnel-like bottom structure guides the flow smoothly to the outlet connection regardless of the location of the inlet connection.
  • the well need not be customized in advance, and the directions of the inlet and outlet connections need not be known until on the installation site, whereby the customization of the well for each particular purpose is simple and easy.
  • the structure of the well is also simple and therefore easy and cost-effective to manufacture.
  • the bottom consists of said sloping part and of a substantially horizontal part resting on the ground, which part resting on the ground is mainly even.
  • the sloping part and the part resting on the ground form together the sturdy structure of the well bottom. Further, as the lower face of the part resting on the ground is mainly even, substantially no voids will be formed under the well, which might cause in the ground changes or stresses that would affect the well, but the lower part of the well may be placed throughout steadily and closely against the ground.
  • the basic idea of a second embodiment is that in the vicinity of the outlet connection the sloping plate is steeper close to the edge of the well than close to the centre of the well bottom, and in other parts than in the vicinity of the outlet connection the slope angle of the sloping plate remains substantially constant. In that case the flow may be guided and turned smoothly and effectively towards the outlet connection and this ensures the smooth flow in the well.
  • Figure 1 shows a well bottom 1.
  • the well bottom 1 consists of a plate 2.
  • the plate 2 is designed such that the well bottom 1 comprises a flow channel 3a towards an outlet connection.
  • the plate 2 is further designed such that the well bottom 1 is funnel-like, i.e. in other parts except for the flow channel 3a the plate 2 is formed to slope towards the centre of the bottom 1.
  • the flow channel 3a is slightly inclined towards the outlet connection.
  • the bottom 1 of the well is illustrated from above.
  • the plate 2 is designed such that, in addition to the flow channel 3a arranged towards the outlet connection, the well bottom 1 comprises a second flow channel 3b, which is arranged from the inlet connection towards the centre of the bottom 1. Except for the second flow channel 3b, the well bottom of Figure 3 is similar to the well bottom of Figures 1 and 2 .
  • the second flow channel 3b is slightly inclined towards the centre of the well bottom 1.
  • the inlet connections shall be arranged clearly, i.e. typically a few centimetres, higher up than the outlet connection.
  • one of the inlet connections need not be placed substantially higher up than the outlet connection. So, if the well is arranged in an even ground, it is not desirable for the sewer line to substantially lose in height in the well, i.e. to arrange the outlet connection substantially lower than the inlet connection, and therefore the solution of Figure 3 is well applicable in cases like this.
  • the solution of Figure 3 may be the bottom of an inspection well, which only receives one inlet connection.
  • the inlet connection and the outlet connection are arranged on the opposite sides of the well, whereby the first flow channel 3a and the second flow channel 3b are arranged in alignment, and consequently, in practice, one continuous flow channel runs through the bottom of the well. Hence the flow from the inlet channel is able to flow smoothly to the outlet connection.
  • Figure 4 shows the lower part of the well 3.
  • the well 3 may be a sewage well, in which the disclosed solutions are particularly useful, because smoothness of flowing is of utmost importance in the sewage wells.
  • the disclosed solutions may also be used, for instance, in connection with drain wells or some other wells.
  • Wells are used, for instance, when several inlet connections are to be joined to one outlet connection, i.e. for instance several inlet sewers to one outlet sewer. Further, wells are used for changing the direction of underground pipework. Wells are also used as inspection wells in direct pipelines. When the well is used as a drain well, it does not necessarily involve a single inlet connection. In that case water runs into the drain well through its cover or set of covers.
  • the well bottom 1 is attached to the well wall 4. Attachment of the bottom 1 to the wall 4 may take place, for instance, by gluing or welding or by using some other suitable attachment method. Further, it is possible to provide the bottom and the wall of the well to be an integral structure, for instance, by means of die casting or rotational casting or by using some other solution producing an integral structure. Further, Figure 4 shows an outlet connection 5, into which the flow from the flow channel 3a is directed.
  • the bottom 1 also consists of a substantially horizontal part 6 resting on the ground, in addition to the sloping plate 2 that provides flow.
  • the lower face of the part 6 resting on the ground is mainly even, whereby it fits closely against the ground below.
  • the part 6 resting on the ground and the plate 2 are interconnected by means of side walls and connection walls 7. It is also possible to use ribs or support poles or other corresponding structures for connecting the part 6 resting on the ground and the plate 2.
  • the connection walls 7 are formed such that an aperture 8 is provided in the middle thereof. In that case the bottom 1 is easy to manufacture, for instance, by rotational casting or blow moulding.
  • the proportion of the apertures 8 of the total surface area of the part resting on the ground is so small, however, that the surface is mainly even.
  • the proportion of the apertures 8 of the total surface area of the part resting on the ground is less than 40%, particularly advantageously less than 20%.
  • the bottom 1 such that the plate 2 is formed to be a separate piece and the part 6 resting on the ground is a separate piece, and these pieces are interconnected, for instance, by welding or gluing. In that case it is also possible to use injection moulding technique and nevertheless result in an even lower face of the part 6 resting on the ground.
  • the plate 2 is formed in the vicinity of the channel 3a leading to the outlet connection 5 to be more sharply sloping close to the edge of the well 3 than close to the centre of the bottom 1. In other parts than in the vicinity of the outlet connection 5 the slope angle of the sloping plate 2 remains substantially constant.
  • the bottom 1 comprises only a flow channel 3a leading towards the outlet connection.
  • the sloping plate is also formed to be steeper close to the edge of the well than close to the centre of the well bottom 1.
  • the slope angle of the sloping plate 2 is substantially constant in all other parts except for in the vicinity of the channel 3a.
  • the inlet connections are arranged on the opposite side of the well with respect to the outlet connection, i.e. in the area of 180 degrees which is furthest away from the outlet connection and where, for instance in the case of Figure 8 , the slope angle of the sloping plate 2 remains constant.
