Definitions

  • the present invention relates to a shaft bottom part for a service connection shaft, wherein the shaft bottom part has a cup part with at least one drain port and at least one inlet port. Moreover, the invention relates to a house connection shaft provided with such a shaft bottom part.
  • Shaft bottom parts or house connection shafts with such a shaft bottom part are used in particular for property drainage in the private but also in the municipal area.
  • such shaft bottom parts are provided with a plurality of inflows and for this purpose have a plurality of inlet nozzles, which are formed radially on the cup part, and at least one opposite the inlet nozzle arranged drain pipe for discharging the introduced from the inlet nozzle into the cup part wastewater.
  • the inlet nozzle in a common horizontal plane with the outlet nozzle and at a common level with a cup base of the shaft bottom part. Due to the fact that the cup part with the nozzle formed on it geometrically from a variety of cylindrical bodies is composed, the cylinder axes intersect in the region of the cup base, the cup base a fachtermino utilizat often referred to as "flume" topography with burr-shaped surveys in the cup base, which form flow resistances, so that can accumulate on these surveys in the wastewater existing solids.
  • the present invention is therefore based on the object to propose a shaft bottom part, which requires a reduced maintenance.
  • the shaft bottom part according to the invention has the features of claim 1.
  • the discharge nozzle is arranged on a cup base of the cup part, and the inlet nozzle is arranged at a vertical distance from the cup base on the cup part.
  • a gradient in the shaft bottom part is formed between the inlet and the outlet, so that the inlet is designed as a "free gravity" inlet, with the result that in the cup part on the inlet inflowing wastewater with increased potential energy impinges on the base of the cup and possibly removes existing deposits, which can then be transported away through the outlet connection. Furthermore, it is achieved by the relative increase of the inlet nozzle relative to the cup base that a Stutzenwandung the inlet nozzle does not continue in the cup base, so that the surface or topography of the Becher grounds is not affected by the Stutzenwandung and a corresponding channel formation in the cup base is avoided.
  • the cup base is formed as a spherical cap, so that a smooth spherical surface in the cup base is made possible, which does not form any flow resistance.
  • a neck wall of the drain neck is arranged in a common plane with a cap tip of the cup part on an underside of the cup part, a drain of the waste water from the area of the cup base is made possible, which takes place at the same level as the cup base, so that even in the transition from the cup base No flow obstacles are formed to the outlet nozzle.
  • the inlet nozzle is arranged in a cylindrical portion of the cup portion formed above the cup base, so that the end cross-section of the inlet nozzle, with which this attaches to the cylinder portion of the cup portion, arranged in a single curved plane, namely the shell plane of the cylinder is, and thus over the cross-sectional height of the inlet identical flow transitions between the inlet nozzle and the cup part are formed.
  • the formation of deposits is counteracted in the region of the inlet.
  • cup part is provided on its convex outer side with support feet, a defined arrangement of the shaft bottom part is facilitated on a substrate.
  • a manufacturing technology particularly simple and at the same time integral design of the support legs is possible if they are formed by integrally formed on a surface of the cup part support webs.
  • the support webs on supporting edges which in a common support plane with the neck wall of the drain neck are arranged so that a particularly stable arrangement of the shaft bottom part is achieved by the combined effect of the support edges and the Stutzenwandung.
  • the house connection shaft according to the invention is provided with a shaft bottom part according to the invention and is therefore characterized by a reduced maintenance.
  • Fig. 1 shows a service connection shaft 10 which is formed in several parts and substantially as independently manageable components a shaft bottom part 11, a connectable by means of a plug connection with the shaft bottom part 11 riser 12 and a connectable by means of a plug connection with the riser 12 manhole cover 13.
  • the individual components of the service connection shaft 10 are preferably made of plastic. However, it is also possible to combine components made of different materials.
  • Fig. 2 shows, the shaft bottom part 11 a cup portion 14, to which in the case of the illustrated embodiment, a drain pipe 15 and three inlet nozzles 16, 17 and 18 are arranged.
  • the discharge nozzle 15 is located on a cup base 19 designed as a spherical cap and opens into the cup portion 14 such that a nozzle wall 20 of the discharge nozzle 15 is arranged in a common plane with a cap tip 28 of the cup base 19, this level simultaneously forming a support plane 21 , in which lower support edges 22 of supporting webs 23, 24, 25 are arranged, which are integrally formed on the underside of the cup base 19 to the cup base.
  • the inlet nozzles 16, 17, 18 are in the case of the present embodiment in a common inlet level, wherein the inlet nozzles 16, 17 and 18 are arranged in a cylinder portion 27 of the cup member 14 at a distance .DELTA.H to the cup base 19, so that a so-called “freestanding "-Base is formed and incident through the inlet nozzle 16, 17, 18 in the cup part 14 liquid flowing with a determined by the distance .DELTA.H to the cup bottom drop height on the cup base 19 and then flows without further height offset from the cup base in the outlet pipe 15.
  • the "free-flowing" inlet ensures that liquid flowing into the cup part strikes the cup base 19 with increased potential energy and, if appropriate, removes existing deposits and can then be transported away through the outlet connection piece 15.
