Definitions

  • the invention relates to a sewer shaft for drainage channels and pipes.
  • Such sewage shafts are essentially known as manholes.
  • a known sewage shaft of this type which is said to be particularly resistant to chemicals, consists of stacked stoneware manhole rings glazed on both sides with an upper reinforced concrete manhole cover with a manhole, and with a manhole base which is formed from a stoneware manhole ring glazed on both sides with a folding sleeve pointing downwards. which is closed at the bottom with a soleplate made of tempered concrete. Above the soleplate, there is a concrete base layer inside the upper part of the shaft as a substructure for a built-in channel.
  • the weak point of such sewage shafts is not the glazed stoneware, but the hitherto usual construction of the manhole base, which does not guarantee that aggressive media cannot penetrate the bottom end of the manhole bottom during the service life of such manholes.
  • All proposed change designs, e.g. Special manhole bases made of plastic or branch cement have also not brought a satisfactory solution.
  • the object of the invention is therefore to develop a sewage shaft consisting essentially of glazed stoneware manhole rings on both sides so that the manhole base has an improved chemical resistance, which is guaranteed for the entire service life of the sewage shaft.
  • the sole plate is no longer made from hardened concrete as before, but from an at least bottom-glazed stoneware plate, special design measures being provided to ensure that the new stoneware sole plate withstands the ground pressure of the installed sewage shaft .
  • these special measures provide that the soleplate is inserted into the seam sleeve of the stoneware manhole ring used as the manhole base and is essentially flush with the floor-standing edges of the seam sleeve overlapping the soleplate and sealed against the seam sleeve with a permanently elastic putty, whereby the sole plate lies flat against the concrete base layer worked into the inside of the manhole base.
  • the concrete base layer has a circumferential shoulder stop which lies together with the sole plate in the rebate sleeve of the manhole base.
  • an expedient embodiment of the invention provides that the soleplate is glazed on both sides.
  • the stoneware soleplate proposed according to the invention is highly resistant to chemicals, in particular also against chlorinated hydrocarbons.
  • the glazing of the soleplate which is directed against the grown soil or, as is often the case, against a clean layer of lean concrete, protects it against any aggressive soil water.
  • the glazing of the soleplate which is expediently also provided on the inside, protects it against aggressive media in the drainage ducts and lines, should this be necessary in the event of a leak in the channel.
  • the proposed stoneware soleplate lies with its edges according to the invention in the rebate sleeve of the manhole base. This ensures that no larger surface pressures can occur on the more sensitive edges of the stoneware soleplate, as can be expected in the region of the bottom edges of the manhole base.
  • the new stoneware sole plate lies against the full surface of the concrete base layer, which is incorporated into the shaft ring that forms the lower part of the shaft.
  • the full-surface contact with a very rigid concrete base layer ensures that the soleplate does not suffer any deflections despite its considerable diameter. It is optimally supported by the full-surface system and can absorb forces without damage, such as those e.g. can result from subsidence.
  • the concrete base layer mentioned has a circumferential shoulder stop which lies together with the soleplate in the rebate sleeve of the manhole base. This creates an immovable and permanent bond between the concrete base layer and the stoneware soleplate.
  • the new stoneware soleplate as well as the encircling shoulder stops of the concrete base layer, which are embedded in the rebate sleeve, are sealed against the inner rebate surface of the manhole base with a chemical-resistant putty, e.g. Asplit, a two-component cement based on phenolic resin from Hoechst. Permanently elastic properties of the putty used are also expedient in order to permit slight expansions and movements of the stoneware soleplate against the overlapping rebate sleeve of the manhole base.
  • a chemical-resistant putty e.g. Asplit, a two-component cement based on phenolic resin from Hoechst.
  • Permanently elastic properties of the putty used are also expedient in order to permit slight expansions and movements of the stoneware soleplate against the overlapping rebate sleeve of the manhole base.
  • the sewage shaft shown is on a grown floor or a cleanliness layer 2.
  • the lower shaft part 3 is made of a stoneware manhole ring 4 glazed on both sides
  • the bottom-facing rebate sleeve 5 is manufactured and has connecting pieces 6 molded into the side walls and an integrated channel 7 with a substructure 8 on the inside. This basic structure of the manhole bases is known.
  • the upper end of the sewage shaft shown as an exemplary embodiment is formed by a reinforced concrete manhole cover 10 with the manhole 11. This is also well known.
  • the lower shaft part 3 has an at least bottom glazed stoneware sole plate 12, which is inserted into the seam sleeve 5 of the lower shaft ring 4 and is essentially flush with the floor-standing edges 13 of the seam sleeve 5 which overlaps the sole plate.
  • the sole plate 12 is sealed against the inner fold surfaces with a chemical-resistant cement 14.
  • the sole plate 12 shown is in full contact with a concrete base layer 15 which is incorporated into the lower part of the manhole.
  • the concrete base layer has a circumferential shoulder stop 16 which, together with the circumferential edge of the soleplate 12, lies in the joint 5 of the manhole base.
  • an additional seal 17 made of a chemical-resistant cement, e.g., between the concrete base layer 15 and the substructure 8 of the channel 7. Asplit.
  • the corrosion protection of the upper reinforced concrete manhole cover 10 which is preferably made in one piece from glazed stoneware and protects the upper concrete cover against rising and condensing aggressive gases.
  • the result is a new sewage shaft that is consistently chemical-resistant from its sole to the top cover.
