Definitions

  • the invention relates to the lower part of a sewage inspection shaft, which is arranged in the private and commercial property drainage on the site or is provided as a transfer structure on a property boundary.
  • Inspection shafts are installed in sewage systems so that inspections can be carried out with video cameras or by inspections.
  • Wastewater inspection shafts are contained in the ground for very long periods of time, whereby they can be exposed to aggressive media from the inside and outside. A high level of corrosion resistance is therefore required.
  • the open inspection channel running in the lower part of the shaft also absorbs the excess media when the shaft is full or when the channel overflows, so that no media penetrate into the ground via the shaft pipe.
  • the layer of concrete that supports the channel body has been clinkered between the channel body and the shaft pipe.
  • the fingers running between the clinker elements and the fingers between the clinker elements and the shaft pipe wall must be sealed.
  • the corresponding area in the shaft pipe is difficult to access and also has an inclination to the horizontal, which hinders the work.
  • the drain plates have a curve that corresponds to the inside radius of the shaft pipe.
  • a maximum of two drain plates are arranged between the channel body and the shaft pipe, so that little or no fingers occur which form sinks for waste water.
  • the drainage plates also cover the edge of the channel body. This ensures that when the wastewater drains away, it completely returns to the channel body. With one or two drain plate (s) for each bank of the channel body, the manhole base can be manufactured with little effort.
  • a drain plate preferably has a shape adapted to the inclination of the drain and its rounding area is vertical and closes flush with the inner wall of the shaft pipe.
  • the sealing effort between the drain plate and the inner wall of the shaft pipe is very low. It is also possible for the drain plate to end vertically with the channel body.
  • the channel body preferably has a U-shape in which the lower half of the channel body is adapted to the shape of the openings in the lateral surface of the shaft pipe and the overall height of the channel body corresponds to the height of the openings.
  • the shaft lower part 10 of an inspection shaft shown in FIG. 1 has a stoneware pipe 12 with a sleeve 14 formed on one end.
  • stoneware pipes or rings can easily be assembled into longer shafts. Stoneware is resistant to corrosion and chemicals.
  • the stoneware pipes can be glazed inside or outside.
  • a concrete filling 18 fills the lower sleeve area adjoining the stoneware slab 16 and forms a flat closure with the edges of the sleeve 14 on the underside of the stoneware pipe 12. It is possible to provide polymer concrete or asbestos concrete 18 for the concrete filling, which counteracts corrosive attacks from the Soil and / or from which liquids in the sewage system are particularly resistant. It is also possible to insert 18 reinforcements, e.g. in the form of a steel grid. The holes for anchoring the reinforcement in the sleeve 14 or in the stoneware pipe 12 must be drilled before the concrete filling 18 is poured.
  • a seal 20 made of polyurethane is provided all around the jacket of the stoneware pipe 12, onto which the socket part of a further stoneware pipe can be placed.
  • the concrete filling 18 in the inner region of the stoneware pipe 12 carries a stoneware channel 24 open at the top.
  • the stoneware channel 24 connects opposite openings 26 and 28 in the stoneware pipe 12.
  • the openings are drilled into the stoneware pipe 12 in the required size and position. This is preferably done before the concrete filling 18 is poured.
  • the sloping surface of the concrete filling 18 between the channel body 24 and the inner wall of the stoneware pipe 12 is covered with a drainage plate 40 made of stoneware.
  • the drain plate 40 is formed in one piece and glazed on its main surfaces.
  • a section along the line VV through the stoneware slab 40 is shown in FIG. 5.
  • the cross section has the shape of a parallelogram, the end faces 41, 42 of which are arranged vertically when the installation is carried out at an angle of inclination a.
  • the lower main surface 44 of the drain plate 40 rests on the concrete filling 18, while the upper side 46 serves as a drain surface for accumulated waste water.
  • the angle between the end faces 42 and the main surfaces 44, 46 results from the difference from a right angle to the angle a.
  • the resulting complement angle to the angle a is between 72 ° and 84 °, preferably between 75 ° and 81 °, preferably 78 °.
  • the drainage plate 40 is optionally glued or applied to the hardened concrete filling 18 as long as the concrete filling 18 has not yet hardened, and is carried by the latter after hardening.
  • the gluing process with a "made-to-measure" drain plate is easy to carry out, despite the limited space inside the shaft pipe.
  • the drain plate 40 can also be integrated into the formwork before the concrete filling 18 is poured. Following the covering of the inclined surface of the concrete filling 18, there is no longer any joint or gap to be sealed.
  • the straight end face 41 is vertically flush with the inside of the side wall of the channel body 24, while the circumferential end face 42 is flush with the inside wall of the stoneware pipe 12.
  • the sealing of the joint between the drain plate 40 and the shaft pipe 12 is omitted or it is at least made significantly easier.
  • the same drainage plate 40 can be used for both inclined surfaces of the concrete filling 18.
  • each of the inclined surfaces of the concrete filling 18 is covered with a pair of two drain plates 40a, 40b, each covering one half of the inclined surface. It has proven to be practical to provide a two-part cover plate 40a, 40b for each of the inclined surfaces, since this is easier to install. Any gap between the cover plates 40a, 40b remains small and can be easily sealed.
  • the adjoining end faces of the drain plates 40a, 40b are arranged vertically. But it is also possible to form them with a slope so that they partially overlap so that the formation of a gap is prevented.
  • Fig. 3 is shown on the right side in dashed lines an excessive drain plate 40, the straight end face 41 is placed on clinker bricks 48 which are bricked up on the side wall of the channel body 24.
  • clinker bricks 48 which are bricked up on the side wall of the channel body 24.
  • a one-piece U-shaped stoneware channel 50 is installed in the manhole base 10 ', the parallel side walls of which extend approximately to the highest point of the Extend openings 26,28.
  • the manufacture of the lower shaft part 10 ' is thereby simplified and accelerated. Only one pouring operation for the concrete filling 18 is required.
  • the concrete filling 18 can, for example on its underside or in the area of the sleeve shoulder, further Stoneware elements, such as slabs, that prevent the passage of aggressive or corrosive media from the floor.
  • the drain plates 40, 40a, 40b and the channel 24, 50 together form an effective barrier against the passage of trace elements of the conveyed waste water or of the groundwater in contact with the foot of the manhole base 10.
