Definitions

  • the invention relates to a process for the production of inspection shafts for pipes laid at different depths, in which a shaft bottom and a shaft upper part are formed in a mold with a core and casting mold bottom and after hardening with the upper edge of the inspection shaft lying in the corridor plane in a total height corresponding to the depth of the pipes Area of the pipes to be checked are used, as well as a control shaft manufactured according to the method.
  • the known inspection shafts for underground pipelines consist of a basic element (shaft floor) with holes for connecting or fitting the pipelines as well as a plurality of interconnectable intermediate parts or extensions with plug-in edges and also an upper part which is usually frustoconical in shape to adapt to the smaller shaft cover diameter (upper part of the shaft) .
  • the alignment of the manhole cover to the corridor level i.e. the level of the respective traffic area (street surface, tread) is currently carried out by installing spacer rings between the manhole cover and the conical manhole top.
  • the normal connecting elements built on the base element such as the intermediate elements or also the conical upper part
  • the mold has a mold bottom that forms the lower edge of the element, while the shape of the upper edge is formed by a press die.
  • the bottom of the mold remains adhering to the product until the material has hardened, while the upper edge hardens without a mold, so that out-of-roundness and similar defects can result.
  • connection points between an exactly shaped smooth side, which is also covered with a suitable film, and another side, which is non-round and uneven, and also has a rough surface. Inspection shafts with such connection points do not meet the tightness requirements. In addition, the poor mechanical weight and pressure distribution easily leads to cracks and breaks.
  • control shaft production has not proven to be particularly adaptable to the different heights and installation conditions of each individual inspection shaft, because of the standard sizes of the one-piece shaft upper part, the length grading module of which has a value that is not below the step height the boarding ladder is inside the inspection shaft.
  • the invention is therefore based on the object of designing a method for the production of inspection shafts and control shafts which are subsequently manufactured for underground pipelines in such a way that the effectiveness of the production is improved with the overall depth of the inspection shaft corresponding to the respective depth of the pipelines and with the corridor level being aligned with the upper level of the inspection shaft .
  • the transport and assembly should be facilitated and in the area of the connection between the upper part of the shaft and the bottom a high durability and tightness and a correspondingly long service life should be guaranteed.
  • the task is based on a method according to the preamble of claim 1 solved the way that the manhole tops are prefabricated in different standard heights and the associated manhole bottom is shaped with the help of a height-adjustable mold bottom in a variable height that complements the total height of the control shaft according to the respective depth of the pipes and the parts thus produced in the area of their on the mold bottoms hardened edges are sealed and firmly connected.
  • the basic idea of the invention is that a sufficient number of one-piece manhole tops prefabricated in standard sizes is available and, in accordance with the required total height of the inspection manhole, an associated manhole bottom is produced in a mold with an adjustable mold bottom at an individually adjusted height. This ensures effective manufacture of the inspection shaft exactly at the required height, at which the manhole cover and the road surface or other traffic areas lie on one level.
  • a corresponding seal is attached to the mold base during the manufacture of the manhole bottom and molded or embedded in the edge during the shaping process. This ensures that the seal and its long service life, as well as a good seal in the joint between the shaft floor and the shaft top, are guaranteed after the shaft upper and the shaft floor have been joined together.
  • the upper part of the manhole and the bottom of the manhole are fastened in the area of their connecting joint by a suitable fastening means, For example, a fastening ring attached to the shaft floor and upper shaft part, rigidly connected to one another.
  • a suitable fastening means For example, a fastening ring attached to the shaft floor and upper shaft part, rigidly connected to one another.
  • the fracture resistance and tightness in the area of the connecting joint is also ensured by the fact that the mold bases remain at the edge after the shaping process until they have hardened, and thus well-rounded, flat edge areas at which the top part of the shaft and the bottom of the shaft are joined are achieved.
  • recesses are formed in the upper section of the upper part of the shaft for temporarily hanging in a lathe, so that the upper part of the shaft, but also - due to its rigid connection to the shaft floor - the assembled control shaft during transport and lowering into the Excavation pit can be handled in a simple manner.
  • the one-piece upper shaft part A is in a known manner with an upper truncated cone-shaped part and a cylindrical part of minimal height or also in one or more module (s) M, i.e. dimension constant, increased height of the cylindrical part by standardized, graded total heights H1 Obtain shaft upper part A, manufactured.
  • the size of a module M corresponds to the distance between the rungs S, which are attached to the inside of the frustoconical part and the cylindrical part of the one-piece manhole top part A.
  • the upper shaft part A is manufactured according to a known method in vibro-compression casting, the casting mold base 2 remaining on the casting after molding, so that an exact shape of the edge 1 is ensured after curing.
  • the one-piece upper shaft part A thus differs from the previously known similar parts by the two recesses 3 and 4 and in terms of the manufacturing process by leaving the mold bottom 2 on the edge of the upper shaft part until the material has hardened.
  • the shaft bottom B is produced by vibro-compression molding in a casting mold formed from a core 11 and a mold shell 12.
  • the height of the shaft base B is determined by the positioning of a mold base 13 arranged within the mold, which, as can be seen from FIG. 2, over a plurality of spacer rings 14 is supported, for example, on a work surface 15.
  • the mold base 13 is brought into position with a spacer ring 14f, a number of further spacer rings 14a, 14b, 14c, 14d and 14e being placed arbitrarily around the core 11 in order to achieve the intended height H2 of the shaft base B.
  • the addition or omission of spacer rings 14 leads to a variable height H2 in the manufacture of each individual manhole base B according to the respective requirements.
  • the spacer rings can also be replaced by oil-hydraulic devices for moving the mold base 13 or fixing it in a specific position.
  • the mold base 13 can also be handled with mechanical, oleodynamic or pneumatic devices which are connected to the core 11, thereby, as shown in FIG. 3, the mold base 13 for the production of manhole bases B with a predetermined height H2 or any changes in height to bring h1, h2, h3, h4 etc. into its specific position.
  • the shaft bottoms B have to be used despite fixed height dimensions are ordered and manufactured according to the respective application, specifically because of the different diameters and angular positions of the connection holes C ', D' for the pipes C, D due to the angular position and size of the pipes C and D to be checked.
  • shaft bottoms B are thus produced which, in addition to the diameters and angles of the connection holes C ', D', which are matched to the respective pipelines, also have a height H2 which can be adapted to the depth of the pipelines and a corresponding sealing system with a seal 17, so that ultimately inspection shafts can be made available which adapt to any position of the pipelines to be checked.
  • the parts which are plugged into one another in the edge area and already provided with a seal 17 - shaft bottom B and shaft upper part A - are attached via one (or more) fastening ring (s) 19 which are (are) attached with dowel screws 20 or other suitable means, connected so that the inspection shaft can be handled in one piece.
  • the mounting ring 19 also has the advantage that it centers the upper shaft part A and the shaft bottom B to each other and counteracts the side pressures caused by the Traffic loads are transmitted via the manhole cover and arise at the connection point between the manhole bottom and the upper part.
  • the recesses 3 and 4 provided according to the invention in the frustoconical part.
  • the recesses 3 and 4 allow the introduction of a cross member 5, which is preferably provided with a centrally arranged eyelet or crank 5 'for hooking in the load hook of a hoist.
  • Attaching the seal during the manufacture of the shaft floor B ensures its quality and operational safety over a long period of time.
  • manhole tops A in standard heights H1 and the manufacture of manhole bottoms B in a specific height H2 to order allows at any time to achieve the desired total height H with one of the shaft tops A in stock and to achieve short delivery times for a complete inspection shaft.
  • the invention is not limited to the exemplary embodiment described, but can also be used for other types of shaft upper parts and floors A and B, for example for square parts or those with inverted edges 1 and 16 with a seal 17 still attached to the floor. These and similar adaptation measures and changes are within the scope of the invention.
